Document structures can be looked at in terms of layout and formatting features such as pages, columns, and so on. Despite the wide diversity of document structures, authors intentions are not taken into account. The concept of intentions is considered here as the effects that authors intend to have on their readers. It includes the reasons that led the authors to write the document and to select certain features instead of others. Intentional structures are a set of relations between document fragments that make explicit authors’ intentions. Intentional structures are generally implicit. We want to help authors to make some of their intentions more explicit. This paper presents a new model based on speech act theory dealing with intentional structures and arguments of how it can be used to enhance written communication."

The usual approach is either to bookmark an entire page when perhaps only one element is relevant, or to copy information from the page and paste it into a second application, such as a text editor. Neither approach is sufficient. Bookmarks over capture data; copying and pasting components implies that users must shift task focus from search tasks to information management tasks. This forced divided attention [8] between knowledge discovery and information management generally compromises both tasks. In this paper, we look at our iterative process to determine requirements for a tool to support the gathering process. In particular, we consider how these requirements have raised other issues about this interactive process, and how, by further evaluation, we hope to develop a richer Web-based design heuristics for within-page collections."

A study of magazine articles, television documentaries and Web sites by the National Geographic Society reveals that in spite of linking, the Web sites make just as linear reading experiences as the older media, although less creative. The study gives nuance to conceptions of linearity and nonlinearity by studying what linearity really is, thus setting nonlinearity in relief. A number of techniques to tie gaps in the reading line together are identified in films and articles. It is argued that by using these techniques in linking, both better reading experiences and less linearity in Web sites could be achieved."

Our fundamental premise is that when people encounter the same document, each may interpret the information it contains differently. Usually, the interpretations are not available to future users of the same information. HyperContext permits users to make these interpretations explicit, and provides support to structure hyperspace around interpretations of documents, rather than around the documents themselves. When a user browses through hyperspace, a document’s context is used to determine which interpretation to present to the user. We also derive a user model of the user’s short-term interests, by first representing the user’s interest in the current document as a salient interpretation before combining it with the salient interpretations of other documents accessed by the user on the same path of traversal. This paper describes the adaptive features of the HyperContext framework, and presents the results of an initial evaluation of one of the features."

In this paper we document the motivation for developing the tool and describe its operation and novel features. Since usability and technology adoption issues are critical for software and hypertext tool uptake, our approach has been to develop a system that is highly usable and sufficiently “pliant” to support and integrate with a wide range of working practices and styles. We discuss some industrial application experience to date, which has informed the design and is informing future requirements. We draw from this some of the perhaps not so obvious characteristics of hypertext tools which are important for successful uptake in practical environments."

In addition, it is potentially easier to understand and apply; these two important factors can contribute to the successful adoption of estimation methods within Web development companies. We believe therefore, analogy-based estimation should be examined further. This paper compares several methods of analogy-based effort estimation. In particular, it investigates the use of adaptation rules as a contributing factor to better estimation accuracy. Two datasets are used in the analysis; results show that the best predictions are obtained for the dataset that first, presents a continuous “cost” function, translated as a strong linear relationship between size and effort, and second, is more “unspoiled” in terms of outliers and collinearity. Only one of the two types of adaptation rules employed generated good predictions."

However, it is difficult for end-users to compose new integrated tools of both existing Web applications and legacy local applications such as spreadsheets, chart tools and database. In this paper, the authors propose a new framework where end-users can wrap remote Web applications into visual components called pads, and functionally combine them together through drag & drop-paste operations. The authors use, as the basis, a meme media architecture IntelligentPad that was proposed by the second author. In the IntelligentPad architecture, each visual component called a pad has slots as data I/O ports. By pasting a pad onto another pad users can integrate their functionalities. The framework presented in this paper allows users to visually create a wrapper pad for any Web application by defining HTML nodes within the Web application to work as slots. Examples of such a node include input-forms and text strings on Web pages. Users can directly manipulate both wrapped Web applications and wrapped local legacy tools on their desktop screen to define application linkages among them. Since no programming expertise is required to wrap Web applications or to functionally combine them together, end-users can build new integrated tools of both wrapped Web applications and local legacy applications."

The core idea of our approach is the use of an organized list of Abstract Tasks to guide the inspector’s activity. An Abstract Task specifies a pattern of inspection operations that the evaluator is required to perform on some specific features of a hypermedia. Abstract Tasks capture our expertise in usability inspection, and express it in a precise and understandable form, so that it can be easily “reproduced”, communicated, and exploited. They help transferring usability expertise from experienced to inexperienced inspectors, and sharing know-how among different evaluators. Thus, different inspectors who systematically apply the same set of Abstract Tasks are more likely to come up with consistent results, and the overall quality of their inspection (in terms of completeness and accurateness of the findings) is greatly improved.####The paper briefly introduces the background of our approach and explains the rationale of Abstract Tasks. It also provides some examples of Abstract Tasks (out of the 43 currently defined) and of inspection results achieved by applying them to inspect WWW sites and commercial CD-ROMs."

(A most radical example of this is Lather and Smithies, Troubling the Angels: Women Living with HIV/AIDS. ) Yet despite such congruneces between feminism and poststructuralism and between hypertext theory and poststructuralism, there have been no examples to date, in theory or practice, of convergence between post-feminist research in the social sciences and a poststructuralist hypertextuality. This paper describes such a hypertextual experiment, a reinscription of Troubling the Angels with additional materials. The point of this experiment is to inquire into the conditions of such writing and reading, and therefore to set an agenda for a future poetics of a poststructuralist feminist research hypertextuality. The paper explores such issues as associative linking, intertextual and intratextual juxtapositions, the unfixing of textual hierarchies in a “rhizomatic” text, non-sequential polylogic, multigeneric collage, and the role of the reader as textual agent."

RNA (Relationship Navigation Analysis) provides a systematic way of identifying useful relationships in application domains. Developers can then implement each relationship as a link.

The purpose of this paper is to describe a study that replicates and extends earlier work that defines and validates two objective navigational metrics [5]. Results of this study confirm the empirical significance of these metrics, support the reliability of their relationship to hypertext comprehension, and provide indirect support for a model of reading comprehension that postulates greater demands on higher-level processing in hypertext compared to traditional print."

As research in the hypermedia field has progressed, the pace at which structure evolves has increased. While the rise in diversity of hypermedia structure has generally been regarded as a positive development, as with many phenomena, it is important to examine structural diversity carefully to avoid the problems that excessive diversity can bring, and to ensure the complete spectrum of potentially beneficial forms of diversity is considered. This paper introduces a diversity space that can serve as an important tool in the study of structural diversity in hypermedia. The purposes of the diversity space are manifold including: to serve as a description space in which the structural diversity of a specific computing environment can be completely and concisely described, to highlight and assist in reconciling differences in structural diversity between computing environments, and to serve as a useful design space in which important diversity related decisions can be considered. To demonstrate the usage of the diversity space, it is first used as a tool to examine the way in which structural diversity developed within the hypermedia field. It is then used to characterize and consider the levels of structural diversity found in the class of computing environments that currently exhibit the highest levels of structural diversity: structural computing systems."

Although the early implementations were true to the breadcrumb metaphor of marking the specific path a user had taken [1], over time the Web convention of using a list of links to represent the location of the current node has become commonplace [5]. Popularized by large directories like Yahoo!, breadcrumbs can reinforce that users are indeed in the “right place”, educate them on the website’s structure, and help them interpret the other links on the page which are contextual to the node’s location. If users feel disoriented [11, 12], they can select one of the breadcrumb links to go to “higher ground” and hopefully proceed with accomplishing their goal. Studies by Bowler et al. [3] and Teng [14] suggest that breadcrumbs are most useful for large and hierarchical sites. The study we report here investigated more powerful breadcrumb navigation constructs within the Open Directory Project. We hope to answer the question if these experimental breadcrumbs can improve performance in key navigation tasks."

The project also seeks to identify requirements and specifications for tools which will support the construction of such dynamically evolving ontologies. Major issues are the guidance of knowledge workers towards soundly constructed ontologies with the help of upper level ontologies and an exploration into language issues - in our case the scenario for constructing ontologies, if German is the language of choice for the domain experts. We also investigate the relationship between terminology and ontology, which we view as a bridge between linguistically motivated and IT motivated standardisation of conceptual models. We envisage knowledge workers’ environments of the future to be tightly integrated systems with their hypertextual capabilities being controlled by ontologically sound interaction and navigation models."

FaceSpace eliminates camera registration errors due to dynamic object tracking and user self-image feedback. FaceSpace had two forms of linking that combine spatial hypermedia with ubiquitous hypermedia: Like an exo-skeleton provides an organism with structure from without, exo-spatial hypertext has the spatial structure applied over the ubiquity of the user’s real-world environment. Endo-spatial hypertext has the spatial structure derived from and attached to the elements of the user’s domain.

While this removes impediments to collaboration, it often deters participants who would rather incubate ideas before bringing them to the group. This is especially the case where creative ideas are at stake. Creating additional wikis with restricted access is a costly solution: it requires participants to distinguish between and navigate between wikis; it requires administrators to construct wikis and their access rules; and it does not account for the movement of content from private to public. In this paper, we describe a system that augments the hypertext in order to solve these problems. This system automatically creates and maintains access rules in response to browsing and editing of the wiki hypertext. In doing so, it improves the targeting of documents in the hypertext, and identifies significant collections of documents and participants."

We are developing mechanisms for manipulating the time-based medium of the evolving information space. Interaction design affords linear timeline traversal and non-linear time travel.

Usually, web pages are created without taken accessibility into account and without using HTML markup correctly to express the functional structure of documents. Both facts pose a lot of problems to VI during information seeking in the web. In this paper we discuss problems related to this issue and how the information seeking process in the WWW could become more effective and efficient for the VI.

Systems that have a very formal representation of these semantics are able to manipulate the hypertexts in a sophisticated way; for example by adapting them or sculpting them at run-time. However, hypertext systems which require the author to write in terms of structures with explicit semantics are difficult/costly to write in, and can be seen as too restrictive by certain authors because they do not allow the playful ambiguity often associated with literary hypertext. In this paper we present a vector-based model of the formality of semantics in hypertext systems, where the vectors represent the translation of semantics from author to system and from system to reader. We categorise a variety of existing systems and draw out some general conclusions about the profiles they share. We believe that our model will help hypertext system designers analyse how their own systems formalise semantics, and will warn them when they need to mind the Semantic Gap between authors and readers."

In this paper, we focus on a type of logical information units called “compound documents”. We argue that the ability to identify compound documents can improve information retrieval, automatic metadata generation, and navigation on the Web. We propose a unified framework for identifying the boundaries of compound documents, which combines both structural and content features of constituent web pages. The framework is based on a combination of machine learning and clustering algorithms, with the former algorithm supervising the latter one. We also propose a new method for evaluating quality of clusterings, based on a user behavior model. Experiments on a collection of educational web sites show that our approach can reliably identify most of the compound documents on these sites."

A method for detecting unusual structures would be useful for identifying such structures so that their impact can be studied and ways to improve Web site effectiveness developed. We viewed the Web as a directed graph, and introduced a higher-order rank based on the non-well-founded set theory. We then developed higher-order rank analysis for detecting irregularities, defined as structures which differ from the typical structure of a target site. To test the effectiveness of our method, we applied it to several Web sites in actual use, and succeeded in identifying irregular structures in the sites."

First, the ability to combine basic WEBSS actions allows users to easily define new high-level functions like, for example, the automatic creation of tables of contents and indexes. Secondly, the behavior of the objects that constitute an electronic book can be enriched by writing scripts that will be automatically executed each time a triggering object performs a specific action. The main originality of our scripting model resides in the fact that a script maybe attached not only to an individual object, but also to all objects of a specific class, or to all objects in a certain set."

By strong typing we mean the direct representation of data semantics as object types in an object database as oposed to a “slotted frames” representation. On the other hand, the flexible emergent nature of structure must be considered in the authoring activity and in this sense premature typing and organizing is counterproductive. Reflecting on these apparently contradictory issues and the past proposals to handle the problem, we extend the strongly typed data model of a prototype hypermedia system, WorldView, to support semi-automatic object submission and type metamorphosis. Weak types are also necessary for some constructs, so they coexist with strong types, but these are enforced. We emphasize the benefits available to the presentation layer of keeping a uniform object oriented structure. In particular we implement a dynamic linking capability that uses queries to retrieve the objects related to some object attribute and suggest other improvements. We stress that most object oriented hypermedia systems are frame-based, especially in what concerns user-defined and emergent structure."

This is a deep and many-faceted issue and very hard to be generally solved. One of the current problems involved is that these search engines focus on content search and not on structure search as investigated in hypertext research. A prerequisite of full-fledged structure search would be that links are first-class objects. This is obviously not the case for the representation of links in the WWW. So, we introduce a rudimentary form of structure search that is based upon content search. In our application of this approach to searching the WWW, we combine this kind of structure search with content search in a meta-search engine. In this way, we are able to reduce the number of irrelevant addresses returned. As a consequence, we propose this approach for searching the World-Wide Web."

This concept provides a mechanism for placing the text information related to images in context, that is, the text is placed within the corresponding objects. Prior to DUIS contextualized preview of links was only possible with text links. The following are the advantages of contextualized preview image map links: (1) Readers can benefit from both the text and the image without making visual saccades between the two. (2) The text does not obstruct the image as is the case in the existing techniques. (3) It is easy for the readers to associate the image and its corresponding image since the two are presented close to each other. The text in the image space may also contain links, and for this reason, it is possible to introduce multiple links for image maps."

Another characterization of CoVer is that CoVer integrates state-oriented versioning concepts with task-oriented versioning concepts. While other version models in general support only one of these groups of concepts, we argue that the explicit composition of versions of complex hypertext networks has to be complemented by automatic version creation in the context of tasks or jobs performed while manipulating the hypertext network and vice versa. Regarding the implementation of version models, it turns out that the state-oriented implementation approach—representing every legal state of a hyperdocument explicitly—and the task-oriented implementation approach—computing versions of complex hypertext networks due to changes executed during a task or job—are interchangeable. While the separation of state- and task-oriented concepts at the conceptual level of the version model is desireable to support version creation and selection for different hypertext applications, the implementation of such a dual model can be based on a single implementation approach. This paper discusses both types of implementation with an emphasis to cope with alternative versions that are in particular meaningful for hypertext publishing applications."

A chunk links to another chunk if they are both close in context space. To evaluate the scheme, we conducted a protocol analysis. Six users of the guideline addressing typical cancer pain management tasks made 30 explicit links. The repertory hypergrid using a neighborhood size of 16 captures 24 of these links.

Navigation is not simply traveling freely along a messy set of links nor querying a database using dialog boxes, and buttons. Unfortunately, navigating into the WWW often looks so. Navigating efficiently in an information space supposes that a previous authoring effort has prepared a hypertext structure especially designed to make the information access scheme fit with the cognitive constraints of the various contexts of the reading task. Thus the navigation model cannot be a simple isomorphic copy of the data model of the presented information ! It relies on the one side on the data model and on the other side on the task model. Designing a hypertext leads to define a mapping between these two models.####This position paper briefly describes the design method we have developed and an automatic generation tool that we have implemented in JA V A as part of a working environment based on this method. The tool allows to map a hypertext structure specified by the designer as a generation model onto a set of source information described as a SGML file. The result of generation is a set of abstract description of page class instances. Another simple tool turns these descriptions into WWW pages and stores them into a database. The reader of this paper is supposed to be aware of hypertext design methods such as HDM [2], 00HDM [4] or RMM [3]."

Databases are designed to store information and the World Wide Web has turned out to be the place for the gathering and distribution of information. While these two seem to be made for each other, there are inherent difficulties in linking them together due to quite different technologies. Nevertheless, it turned out that most real-life Web applications need an underlying database [l] to be stable, flexible and scalable. Appropriate design methodologies are hence needed to implement complex functionality. Moreover, there already exist databases which people want to connect to the Web with similar functionality as in classic implementations. Most of them rely on the proven technology of relational databases.####This paper introduces a new design methodology for the integration of databases and the Web: The key idea of this approach is to use links to solicit user selections. Control elements are thus constructed of sets of links grouped together and called Passive HTML Controls (PHC). The links of a PHC are called elements. These links (elements) are a means of user interaction, no crossreferences or links for navigation. Each element has two parts: The anchor tag defining the link of the element and the content of the tag defining the output string of the element. This approach is reasonable for a typical Web application where most user interactions consist of browsing and collecting information from the database. The possible values for user input are predefined in these cases. Forms are only used where user input has to be gathered."

Instead, a network organization of information units of different forms (textual, graphical, pictorial and even auditive presentation modes may be combined) is provided. Documents organized this way are called “hypertexts”. However, two questions arise immediately when an effort is made to build information systems on the basis of this conception: What are the “units” constituting a hypertext? What sort of links between the units will be provided? Most approaches to hypertext systems impose the task of deciding these questions on the authors of hypertexts, thus the systems are hypertext management devices (e.g. CHRISTODOULAKlS ET AL. 86, WOELK ET AL. 86). The approach taken in this paper leaves a more active role to the software by applying knowledge based techniques. The starting point is the automatic content analysis of machine-readable full-text documents which may be downloaded from a full-text data base. The analysis process results in a partitioning of the document into thematically coherent text passages, which are one kind of node of the hypertextual version of this document. Other nodes contain graphics, tables and summarizations. The content analysis is accomplished by a semantic parser, which has access to an explicit model of the discourse domain. The TOPIC-System (HAHN/REIMER 86) comprises prototypical implementations of these components. Due to the semantic modeling relations between the nodes may be formally defined in order to provide content oriented browsing facilities. The graphical retrieval system TOPOGRAPHIC (THIEL/HAMMWÖHNER 87) employs an already implemented subset of them to guide users to relevant text parts. In this paper we outline a structure model for hypertexts based on partial representations of the meaning of text parts. Formal definitions of content oriented relations between such text units are given in terms of a logic specification language."

The problem is difficult because: (i) the textual content of blogs is often noisy, (ii) comments do not always target passages of the posts and, (iii) comments are not equally useful for identifying important passages. We have developed a system for selecting commented passages which takes as input blog posts and their comments and delivers, for each post, the sentences of the post which are the most commented and/or the most discussed. Our approach combines three steps to identify commented passages of a post. The first step is to remove the complexity of processing the contents of posts and comments using heuristics adapted to the language of the blog. The second step is to find useful comments and assigns them a degree of relevance using a model automatically built and validated by an expert. The third step is to identify important passages using relevant comments. We conducted two experiments to evaluate the usefulness and the effectiveness of our approach. The first study show that in only 50% of the posts, the most commented sentence elicited by our approach corresponds to the post extract generated using generic summarization. In the second study, human participants confirmed that, in practice, selected passages are frequently commented passages."

When designing new engines, engineers must obtain knowledge gained from maintenance of existing engines to identify possible areas of concern. We developed a Semantic Web based document repository for transferring front-line maintenance knowledge to design. The Semantic Web is an ideal candidate for this application because of the size and distributed nature of an aerospace manufacturer’s operation. The Semantic Web allows us to dynamically cross reference documents with the use of an ontology. However, during the design and implementation of this project, we found deficiencies in the W3C1 recommended Semantic Web query language SPARQL. It is difficult to answer questions our users sought from the document repository using SPARQL. The problem is that SPARQL is designed for handling textual queries. In industrial applications, many common textual and semantic questions also contain a numerical element, be it data summarization or arithmetic operations. In this paper, we generalize the problems we found with SPARQL, and extend it to cover web applications in non-aerospace domains. Based on this analysis, we recommend that SQL-styled grouping, aggregation and variable operations be added to SPARQL, as they are necessary for industrial applications of the Semantic Web. At the moment, to answer the non-textual questions we identified with an RDF store, custom written software is needed to process the results returned by SPARQL. We incorporated the suggested numerical functionalities from SQL for an example query, and achieved a 21.7% improvement to the speed of execution. More importantly, we eliminate the need of extra processing in software, and thus make it easier and quicker to develop Semantic Web applications."

We describe the communication dynamics by several simple contextual properties of communication, e.g. the number of posts, the number of comments, the length and response time of comments, strength of comments and the different information roles that can be acquired by people (early responders / late trailers, loyals / outliers). We study a “technology-savvy” community called Engadget (http://www.engadget.com). There are two key contributions in this paper: (a) we identify information roles and the contextual properties for four technology companies, and (b) we model them as a regression problem in a Support Vector Machine framework and train the model with stock movements of the companies. It is interestingly observed that the communication activity on the blogosphere has considerable correlations with stock market movement. These correlation measures are further cross-validated against two baseline methods. Our results are promising yielding about 78% accuracy in predicting the magnitude of movement and 87% for the direction of movement."

In this paper, we present a new approach to identifying similar documents based on a conceptual tree-similarity measure. We represent each document as a concept tree using the concept associations obtained from a classifier. Then, we make employ a tree-similarity measure based on a tree edit distance to compute similarities between concept trees. Experiments on documents from the CiteSeer collection showed that our algorithm performed significantly better than document similarity based on the traditional vector space model."

We identify a class of Web tasks - information-gathering - that can be facilitated by providing links to pages related to the page the user is currently viewing. We define three kinds of intentional relationships that correspond to whether the user is a) seeking sources of information, b) reading pages which provide information, or c) surfing through pages as part of an extended information-gathering process. We show that these three relationships can be mined using a combination of textual and link information and provide three scoring mechanisms that correspond to them: SeekRel, FactRel and SurfRel. These scoring mechanisms incorporate both textual and link information. We build a set of capacitated subnetworks, each corresponding to a particular keyword. Scores are computed by computing flows on these subnetworks. The capacities of the links are derived from the hub and authority values of the nodes they connect, following the work of Kleinberg (1998) on assigning authority to pages in hyperlinked environments. We evaluated our scoring mechanism by running experiments on four data sets taken from the Web. We present user evaluations of the relevance of the top results returned by our scoring mechanisms and compare those to the top results returned by Google’s Similar Pages feature, and the Companion algorithm (Dean and Henzinger, 1999)."

Web 2.0 applications such as blogs, bookmarking, music, photo and video sharing systems are among the most popular; and all of them incorporate a social aspect, i.e., users can easily share information with other users. But due to the diversity of these applications—serving different aims— the Social Web is ironically divided. Blog users who write about music for example, could possibly benefit from other users registered in other social systems operating within the same domain, such as a social radio station. Although these sites are two different and disconnected systems, offering distinct services to the users, the fact that domains are compatible could benefit users from both systems with interesting and multi-faceted information. In this paper we propose to automatically establish social links between distinct social systems through cross-tagging, i.e., enriching a social system with the tags of other similar social system(s). Since tags are known for increasing the prediction quality of recommender systems (RS), we propose to quantitatively evaluate the extent to which users can benefit from cross-tagging by measuring the impact of different cross-tagging approaches on tag-aware RS for personalized resource recommendations. We conduct experiments in real world data sets and empirically show the effectiveness of our approaches."

The tool works by adding additional hyperlinks to blogs, links which connect blog entries addressing similar topics.

An evaluative exercise, centred upon the unsupervised labeling of blog articles, confirms the effectiveness of this approach."

A great deal of this content is ideal for incorporation into personalised eLearning experiences. However the discovery, harvesting and incorporation of appropriate educational material have proven to be complex and arduous tasks.####Traditional educational hypertext systems are based upon the generation of links and anchors between content objects [1]. However the dynamic incorporation of open corpus educational content in eLearning requires the generation of a relationship between educational concepts and the hypertext documents. One approach to create this overlay between concept and content is to use a Mindmap interface to allow learners to explore and associate hypertext content with knowledge maps of their own creation.####This paper presents the Open Corpus Content Service (OCCS), a framework that uses the hypertext structure of the WWW to provide methods of educational content discovery and harvesting. The OCCS semantically examines linked content on both the WWW and in digital content repositories, and creates concept specific caches of content. The paper also introduces U-CREATe, a novel user-driven Mindmap interface for supporting the exploration and assembly of content cached by the OCCS, in a pedagogically meaningful manner. The combination of these systems benefits both the educator and learner, empowering the learner through ownership of the educational experience and allowing the educator to focus on the pedagogical design of educational offerings rather than content authoring."

Our first contribution is that we developed an algorithm that incorporates a comprehensive set of heuristics, some of which are novel, in a single unified framework. The second contribution is that we conducted a relatively large-scale experiment, and analysis of our results revealed the characteristics of the problem of finding movedWeb pages. We demonstrated empirically that the problem of searching for moved pages is different from typical information retrieval problems. First, it is impossible to identify the final destination until the page is moved, so the index-server approach is not necessarily effective. Secondly, there is a large bias about where the new address is likely to be and crawler-based solutions can be effectively implemented, avoiding the need to search the entire Web. We analyzed the experimental results in detail to show how important each heuristic is in real Web settings, and conducted statistical analyses to show that our algorithm succeeds in correctly finding new links for more than 70% of broken links at 95% confidence level."

To provide solutions to these issues, this paper presents Knowledge Puzzle, a tool for knowledge construction from the Web. Its main contribution to Web-based learning is the personalization of information structure on the Web to cope with the knowledge structure in the learner’s mind. Self-directed learners will be able to adapt the path of instruction on the Web to their way of thinking, regardless of how the Web content is delivered. The way to achieve that is to provide learners with a meta-cognitive tool that enables them to bring knowledge gained from the Web to the surface and visualize what they have in mind. Once we get the learner’s viewpoint externalized, it will be converted to a hypermedia layer that will be laid over the Web pages visited by the learner. The attached layer adapts the views of Web pages to the learner’s information needs by associating information pieces that are not already linked in hyperspace and attaching the learner’s notes to the page content. Finally, a hypertext version of the whole constructed knowledge is produced to enable fast and easy reviewing."

We therefore propose a generalization of connected components, m-hyperincident connected components. We show that decomposing tagging networks into 2-hyperincident connected components yields a characteristic component distribution with a salient giant component that can be found across various datasets. This pattern changes if the underlying formation process changes, for example, if the hypergraph is constructed from search logs, or if the tagging data is contaminated by spam: It turns out that the second to 129th largest components of the spam-labeled Bibsonomy dataset are inhabited exclusively by spam users.

HyWrite is backed by an elaborate didactic design based on students’ active participation and all-round involvement in the learning process. The didactic goals pursued are on the one hand the acquisition of a set of primary skills like for instance essay writing and on the other hand getting acquainted with a host of complementary skills not explicitly mentioned by the curriculum yet presupposed by the Information and Knowledge Society. These skills are dealt with in a systematical approach and reflect the actual state of affairs, namely what “every schoolboy and girl should know”.[3] An overview of the above mentioned competences is available in the core skill cluster below. The skill cluster under discussion covers competences pertaining to four ranges of action: writing techniques, media literacy, aesthetic features combined with ergonomic design from the point of view of accessibility and usability, and — last but not least — the social skills imposed by cooperative work."

The evaluation showed how subsequences could be used to understand the information pathways users chose to follow within a website, and that exact and inexact matching provided complementary ways of identifying information that may have been of interest to a whole community of users, but which was only found by a minority. This illustrates how string-matching could be used to improve the structure of hypertext collections."

Here, we suggest a Web based solution for rediscovering these reverse links, and develop a series of experiments to demonstrate our approach. Simply our algorithm involves parsing a Web server’s log file, identifying each Web page viewed and saving an ordered list of referrers within a ‘name-matched’ XML file. This file is then used as a link point within a standard XHTML Web-page using a freely available Javascript library. While we have not performed any comprehensive user evaluation initial qualitative results suggest users are positive regarding our additions and that widespread adoption would increase user satisfaction due to constancy of the browsing experience."

This is done by seamlessly personalizing the support offered to each individual user, as they browse across multiple websites, by modeling the user’s interactions and then augmenting information access points, such as links, on each independent website. Cross-Site Personalization is realized as a third-party API offering Personalisation As a Service to ensure cross-site and cross-device usage. The personalized augmentations are provided through module extensions for the Web-based Content Management Systems (WCMS) Drupal. The approach is non-intrusive and does not limit or alter the user’s information access paradigm. This is done by visually augmenting the existing hyperlinks on webpages. The design of the API ensures user’s privacy by not disclosing personal browsing information to the websites. Rather, this approach recommends how each website may adapt their information and navigation structures to meet user’s information needs. Finally, the approach ensures user control and scrutiny. The user can enable/disable CSP at any time and view any information collected. The evaluation of the approach was conducted with a real-world use case. This paper introduces the architecture, a prototype implementation and encouraging evaluation results."

This form of online collective contagion has provided many benefits to society, such as providing reassurance and emergency management in the immediate aftermath of natural disasters. However, it also poses a potential risk to vulnerable Web users who receive this information and could subsequently come to harm. One example of this would be the spread of suicidal ideation in online social networks, about which concerns have been raised. In this paper we report the results of a number of machine classifiers built with the aim of classifying text relating to suicide on Twitter. The classifier distinguishes between the more worrying content, such as suicidal ideation, and other suicide-related topics such as reporting of a suicide, memorial, campaigning and support. It also aims to identify flippant references to suicide. We built a set of baseline classifiers using lexical, structural, emotive and psychological features extracted from Twitter posts. We then improved on the baseline classifiers by building an ensemble classifier using the Rotation Forest algorithm and a Maximum Probability voting classification decision method, based on the outcome of base classifiers. This achieved an F-measure of 0.728 overall (for 7 classes, including suicidal ideation) and 0.69 for the suicidal ideation class. We summarise the results by reflecting on the most significant predictive principle components of the suicidal ideation class to provide insight into the language used on Twitter to express suicidal ideation."

But in spite of rapid growth of the number of users and projects, a project success rate at large has been decreasing because of launching projects without enough preparation and experience. To solve the problem, in this paper we (i) collect the largest datasets from Kickstarter, consisting of all project profiles, corresponding user profiles, projects’ temporal data and users’ social media information; (ii) analyze characteristics of successful projects, behaviors of users and understand dynamics of the crowdfunding platform; (iii) propose novel statistical approaches to predict whether a project will be successful and a range of expected pledged money of the project; and (iv) develop predictive models and evaluate performance of the models.

Linked profiles can help companies like Disney to build psychographics of potential customers and segment them for targeted marketing in a cost-effective way. Existing methods link profiles by observing high similarity between most recent (current) values of the attributes like name and username. However, for a section of users observed to evolve their attributes over time and choose dissimilar values across their profiles, these current values have low similarity. Existing methods then falsely conclude that profiles refer to different users. To reduce such false conclusions, we suggest to gather rich history of values assigned to an attribute over time and compare attribute histories to link user profiles across networks. We believe that attribute history highlights user preferences for creating attribute values on a social network. Co-existence of these preferences across profiles on different social networks result in alike attribute histories that suggests profiles potentially refer to a single user. Through a focused study on username, we quantify the importance of username history for profile linking on a dataset of real-world users with profiles on Twitter, Facebook, Instagram and Tumblr. We show that username history correctly links 44% more profile pairs with non-matching current values that are incorrectly unlinked by existing methods. We further explore if factors such as longevity and availability of username history on either profiles affect linking performance. To the best of our knowledge, this is the first study that explores viability of using an attribute history to link profiles on social networks."

Understanding how these tactics are operationalised and knowing the situations that bring about such tactics paves the way towards modeling navigation behaviour. Modeling the navigation of users is of utmost importance as it allows not only to predict interactive behaviour, but also to assess the appropriateness of the content in a link, the information architecture of a site and the design of a web page. Current navigation models do not consider the extreme adaptations, namely coping tactics, that screen reader users undergo on the Web. Consequently, their prediction power is lessened and coping tactics are mistakenly considered outlying behaviours. We draw from existing navigation models for sighted users to suggest the incorporation of emerging behaviours in navigation models for screen reader users. To do so, we identify the navigation coping tactics screen reader users exhibit on the Web, including deliberately clicking on low scented links, escaping from useless or inaccessible content and backtracking to a shelter. Our findings suggest that, especially in problematic situations, navigation is not driven by information scent or utility, but by the need of increasing autonomy and the need of escaping from the current web patch."

When an activity expands across different websites, the user is left alone in the effort to aggregate the resources and services required in carrying out these cross-site activities. This results in a lost of focus, and constant switching among websites. The problem is that these webflows tend to be highly personal and hence, difficult to foreseen. Therefore, we advocate for users to be empowered to define these roadmaps upon the websphere. This work introduces CORSET, a Firefox plugin that lets users create their own webflows in the browser side. A corset is defined as a state-transition diagram, and results in “layer hyperlinks” being superimposed upon the participating websites. The expressiveness of CORSET is validated against four webflow patterns: the hub-and-spoke pattern, the guided-tour pattern, the parallel pattern and the interruption pattern. The benefits include (1) mitigation of activity fragmentation, (2) consolidation of webflow knowledge that is now amenable to sharing, (3) reduction in the number of clicks, and (4), alleviation of waiting times through page pre-load."

We demonstrate a correlation between the level of attention that users devote to a story, and the position of the most noticeable graphic element on the side bar.

For that end, we devise a novel behavioral model of authors and readers, where authors try to influence readers by generating “attractive” content, which is both relevant and unique, and readers can become authors themselves by further citing or referencing content made by other authors. The model is realized by means of a content-based citation graph, where nodes represent authors with their generated content and edges represent reader-to-author citations. To find the top influencers for a given topic, we first profile the content of authors (nodes) and citations (edges) and derive topic-based similarity scores to the topic, which further model the unique and relevant topic interests of users. We then present three different extensions of the Topic-Sensitive PageRank algorithm that exploit the similarity scores to find topic-based influencers. We evaluate our solution on a large real-world dataset that was gathered from Twitter by measuring information diffusion in social networks. We show that, overall, our methods outperform several state-of-the-art methods. This work further serves as an evidence that the topic uniqueness aspect in user interests within social media should be considered for the influencers detection task; this is in comparison to previous works that have solely focused on detecting topic-based influencers using the combination of link structure and topic-relevance."

Much remains to be learned about collaborative information seeking within open web social spaces. This paper is an attempt to better understand either implicit or explicit collaboration by studying Twitter, one of the most popular and widely used social networks. We study in particular the complex intertwinement of human interactions induced by both collaboration and social networking. We empirically explore explicit collaborative interactions based on focused conversation streams during two crisis. We identify structural patterns of temporally representative conversation subgraphs and represent their topics using Latent Dirichlet Allocation (LDA) modeling. Our main findings suggest that: 1) the critical mass of collaboration is generally limited to small-sized flat networks, with or without an influential user, 2) users are active as members of weakly overlapping groups and engage in numerous collaborative search and sharing tasks dealing with different topics, and 3) collaborative group ties evolve within the time-span of conversations."

To obtain correct web information and support effective decision making, it is important to enhance searcher credibility assessment and develop algorithms to detect suspicious information. In this paper, we investigate how credibility alarms for web search results affect searcher behavior and decision making in information access systems. This study focuses on disputed topic suggestion as a credibility alarm approach. We conducted an online user study in which 92 participants performed a search task for health information. Through log analysis and user surveys, we confirmed the following. (1) Disputed topic suggestion in a search results list makes participants spend more time browsing pages than ordinary search conditions, thereby promoting careful information seeking. (2) Disputed topic suggestion during web browsing does not change participant behaviors but works as complementary information. This study contributes to system designs to enhance user engagement in critical and careful information seeking."

Our work is guided by the activation equation of the cognitive model ACT-R, which states that the usefulness of information in human memory depends on the three factors usage frequency, recency and semantic context. It is our aim to shed light on the influence of these factors on tag reuse. In our experiments, we utilize six datasets from the social tagging systems Flickr, CiteULike, BibSonomy, Delicious, LastFM and MovieLens, covering a range of various tagging settings. Our results confirm that frequency, recency and semantic context positively influence the reuse probability of tags. However, the extent to which each factor individually influences tag reuse strongly depends on the type of folksonomy present in a social tagging system. Our work can serve as guideline for researchers and developers of tag-based recommender systems when designing algorithms for social tagging environments."

In the current study, we aim to build a recommendation system for businesses to provide suggestions for business collaboration. Based on historical data from Yelp that shows two businesses being reviewed by the same users within a same season, we were able to identify businesses that might attract the same customers in the future, and hence provide them with a collaboration suggestion. Our results suggest that the evidence - two businesses sharing reviews from same users - can provide recommendations for businesses to pursue future collaborative marketing opportunities."

This study uses 279 journal entries from individuals with chronic pain in order to estimate the positive and negative affect scores reported directly by participants. We use Lasso to select the features that are most predictive of affect. Our results indicate that the model combining human coders and ATA accounts for the most variance in self-reported positive affect scores, resulting in adjusted R-squared=0.36. For negative affect scores, we obtain a lower adjusted R-squared=0.30 with the combined model, however, ATA results in significantly higher adjusted R-squared=0.27 compared to the model using only human coders, R-squared=0.14. This suggests that utilizing human coders may be the most beneficial when the focus is on positive affect, but automated text analysis may be sufficient when studying negative affect."

Reddit relies on the Wisdom of the Crowd (WotC) from its community as well as selected moderators to manage its content. We argue that this approach suffers from the cold start in collecting user votes and is at risk of user bias, particularly a group-think mentality. Besides that, managing the large collection of content on Reddit is expensive. In our study, we explore the estimation of relative user expertise through various content-agnostic approaches. We show that it is possible to infer information quality on Reddit using the expertise of the authors.

The focus of previous works has been on analyzing user-generated content such as tweets to infer user interests. Therefore, these previous studies were limited to active users who have been actively generating content. On the other hand, with the percentage of passive use of OSNs on the rise, some researchers investigated different types of information about followees (i.e., people that a user is following) such as tweets, usernames, and biographies to infer user interests for passive users who use OSNs for consuming information from followees but who do not produce any content. Although different types of information about followees have been exploited, list memberships (a topical list which other Twitter users can freely add a user into) of followees have not yet been investigated extensively for inferring user interests.####In this paper, we investigate list memberships of followees, to infer interest profiles for passive users. To this end, we propose user modeling strategies with two different weighting schemes as well as a refined interest propagation strategy based on previous work. In addition, we investigate whether the information from biographies and list memberships of followees can complement each other, and thus improve the quality of inferred interest profiles for passive users. Results show that leveraging list memberships of followees is useful for inferring user interests when the number of followees is relatively small compared to using biographies of followees. In addition, we found that combining the two different types of information (list memberships and biographies) of followees can improve the quality of user interest profiles significantly compared to a state-of-art method in the context of link recommendations on Twitter."

However, such characteristics are not often clearly stated by Twitter users, so researchers must turn to other means to ascertain various categories of identity. In this paper, we discuss the challenge of detecting the nationality of Twitter users using rich features from their profiles. In addition, we look at the effectiveness of different features as we go about this task. For the case of a highly diverse country—Qatar—we provide a detailed network analysis with insights into user behaviors and linking preference (or the lack thereof) to other nationalities."

We present a prototype for contextual knowledge mining that enables federated access and querying of entities across hundreds of enterprise and open datasets pertaining to cities. The proposed system is able to (1) lift raw tabular data into a connected and meaningful structure, contextualized within the Web of Data, and (2) support novel search and exploration tasks, by identifying closely related entities across datasets and models.

Our primary finding is that over the years there are increasing differences with respect to conversation use and information use in Twitter. We studied the interaction network between users to understand whether assumptions about the structure of the conversations hold over time and between different types of interactions, such as retweets, replies, and mentions. While ‘people come and people go,’ we want to understand what keeps people staying engaged with the conference on Twitter. By casting the problem as a classification task, we find different factors that contribute to the continuing participation of users to the online Twitter conference activity.

However not all micro-reviews are equally important, especially since a venue owner should already be familiar with his venue’s primary aspects. Instead we envisage that a venue owner will be interested in micro-reviews that are unexpected to him. These can arise in many ways, such as users focusing on easily overlooked aspects (by the venue owner), making comparisons with competitors, using unusual language or mentioning rare venue-related events, e.g. a dish being contaminated with bugs. Hence in this study, we propose to discover unexpected information in micro-reviews, primarily to serve the needs of venue owners.####Our proposed solution is to score and rank micro-reviews, for which we design a novel topic model, Sparse Additive Micro-Review (SAMR). Our model surfaces micro-review topics related to the venues. By properly offsetting these topics, we then derive unexpected micro-reviews. Qualitatively, we observed reasonable results for many venues. We then evaluate ranking accuracy using both human annotation and an automated approach with synthesized data. Both sets of evaluation indicate that our novel topic model, Sparse Additive Micro-Review (SAMR) has the best ranking accuracy, outperforming baselines using chi-square statistics and the vector space model."

However, social, cultural and political divisions continue to separate users and information into different social media systems. Twitter and Facebook, for example, are strictly forbidden in mainland China. As a result, 21.97% of all world-wide Internet users are thus excluded from participating in these platforms. In this study, we investigate whether the dynamics of information diffusion, modeled as the adoption patterns of topical hashtags, differ between the communities of the mentioned social media sites as a result of this separation. Specifically, we compare Weibo and Twitter, the two largest micro-blogging sites serving respectively the Chinese population and the rest of the world, by exploring the similarities and differences of how their respective users adopt new information. By leveraging sophisticated community detection algorithms and heterogeneous graph mining methods, we investigate and compare how the different characteristics of these communities influence information diffusion and adoption. Experimental results show that while community-specific information influences topic diffusion and adoption in both environments, novel features, extracted from heterogeneous graph based communities, have a greater effect on Weibo information adoption than Twitter. We also find that users sharing hashtags is an important factor in information diffusion on both Twitter and Weibo, whereas user mentions are important for Weibo, but less so for Twitter. Overall, we conclude that Weibo and Twitter differ sharply in how their users adopt information in response to similar factors."

Such noise brings difficulties to improve the accuracy of item recommendations. To eliminate the noise of tags, in this paper we propose to use the multiple relationships among users, items and tags to find the semantic meaning of each tag for each user individually.

In addition, the user and item-based collaborative filtering combined with the content filtering approach are explored. The effectiveness of the proposed approaches is demonstrated in the experiments conducted on real world datasets collected from Amazon.com and citeULike website."

While an explicit social network is not necessarily present in these sites, it is still possible that users influence one another in the process of item adoption through various implicit mechanisms. In this paper, we study how we can capture the implicit influences among the users in a social sharing site. We propose a probabilistic model for user adoption behaviour, where we assume that when user adopts an item, he would pick a user and choose from the set of items that this user has adopted. By using the model, we estimate the probability that one user influences another user in the course of item adoption, based on the temporal adoption pattern of the users. We carry out empirical studies of the model on Delicious, a popular social bookmarking site. Experiments show that our model can be used to predict item adoption more accurately than using collaborative filtering techniques. We find that the strength of implicit influence various across different topics. We also show that our method is able to identify the influential users who are more likely to possess items interested by other users. Our model can be used to study the dynamics in a social sharing site and to complement collaborative filtering in recommendation systems."

To construct a social network among Wikipedians we look to mutual interaction on the user talk pages of Wikipedia editors. As our data set, we analyze the communication networks associated with 3085 featured articles - the articles of highest quality in the English Wikipedia, comparing it to the networks of 80154 articles of lower quality. As the metric to assess the quality of collaboration, we measure the time of quality promotion from when an article is started until it is promoted to featured article. The study finds that the higher pre-existing social capital of editors working on an article is, the faster the articles they work on reach higher quality status, such as featured articles. The more cohesive and more centralized the collaboration network, and the more network members were already collaborating before starting to work together on an article, the faster the article they work on will be promoted or featured."

This is likely due to its popularity and scale, but also to the fact that large amounts of data about its formation and evolution are freely available to inform and validate theories and models of online collaboration. As part of the development of such approaches, revert detection is often performed as an important pre-processing step in tasks as diverse as the extraction of implicit networks of editors, the analysis of edit or editor features and the removal of noise when analyzing the emergence of the content of an article. The current state of the art in revert detection is based on a rather naive approach, which identifies revision duplicates based on MD5 hash values. This is an efficient, but not very precise technique that forms the basis for the majority of research based on revert relations in Wikipedia. In this paper we prove that this method has a number of important drawbacks - it only detects a limited number of reverts, while simultaneously misclassifying too many edits as reverts, and not distinguishing between complete and partial reverts. This is very likely to hamper the accurate interpretation of the findings of revert-related research. We introduce an improved algorithm for the detection of reverts based on word tokens added or deleted to adresses these drawbacks. We report on the results of a user study and other tests demonstrating the considerable gains in accuracy and coverage by our method, and argue for a positive trade-off, in certain research scenarios, between these improvements and our algorithm’s increased runtime."

A particularly interesting approach is link traversal based query execution which proposes to integrate the traversal of data links into the creation of query results. Hence - in contrast to traditional query execution paradigms - this does not assume a fixed set of relevant data sources beforehand; instead, the traversal process discovers data and data sources on the fly and, thus, enables applications to tap the full potential of the Web.####While several authors have studied possibilities to implement the idea of link traversal based query execution and to optimize query execution in this context, no work exists that discusses theoretical foundations of the approach in general. Our paper fills this gap.####We introduce a well-defined semantics for queries that may be executed using a link traversal based approach. Based on this semantics we formally analyze properties of such queries. In particular, we study the computability of queries as well as the implications of querying a potentially infinite Web of Linked Data. Our results show that query computation in general is not guaranteed to terminate and that for any given query it is undecidable whether the execution terminates. Furthermore, we define an abstract execution model that captures the integration of link traversal into the query execution process. Based on this model we prove the soundness and completeness of link traversal based query execution and analyze an existing implementation approach."

These short URLs can then be shared and diffused by users via online social media, e-mail or other forms of electronic communication. When another user clicks on the shortened URL, she will be redirected to the underlying long URL. Shortened URLs can serve many legitimate purposes, such as click tracking, but can also serve illicit behavior such as fraud, deceit and spam. Although usage of URL shortener services today is ubiquituous, our research community knows little about how exactly these services are used and what purposes they serve. In this paper, we study usage logs of a URL shortener service that has been operated by our group for more than a year. We expose the extent of spamming taking place in our logs, and provide first insights into the planetary-scale of this problem. Our results are relevant for researchers and engineers interested in understanding the emerging phenomenon and dangers of spamming via URL shortener services."

Lastly we provide a predictive model for the quality of any given web page title in terms of its discovery performance.

We identify a power law distribution in browser metrics comprising “outclicks” and tab switches, which signify the degree of parallel browsing. We find that users switch tabs at least 57.4% of the time, but user activity, measured in pageviews, is split among tabs rather than increasing overall activity. Finally, analysis of a subset of the logs focused on Web search shows that while the majority of users do not branch from search engine result pages, the degree of branching is higher for non-navigational queries. Our findings have design implications for Web sites and browsers, search interfaces, and log analysis."

Unfortunately, changes on the application normally also require updates to the addressing patterns. This raises pattern robustness as a main concern. This papers focuses on the (semi) automatic generation of change-resilience XPath patterns. Two different categories of changes are addressed, i.e. in space (e.g., different personalizations of a page) and in time (e.g., site upgrades), by exploiting two different techniques: induction and simulated annealing. These techniques permit to obtain XPath patterns “resilient-enough” to a “controlled set of page designs”. SiSy, a tool that assists the user in obtaining resilient XPath expressions, was born out of this approach. The approach is tested for two websites (www.yahoo.com and www.elmundo.es), identifying 23 updates to which XPath expressions were resilient to 62% of the undertaken changes."

It leaves users defenseless against various spamming or “shilling” attacks. Other social Web-based systems, however, allow users to self-select peers and build a social network. We argue that users’ self-defined social networks could be valuable to increase the quality of recommendation in CF systems. To prove the feasibility of this idea we examined how similar are interests of users connected by self-defined relationships in a collaborative tagging systems Citeulike. Interest similarity was measured by similarity of items and meta-data they share and tags they use. Our study shows that users connected by social networks exhibit significantly higher similarity on all explored levels (items, meta-data, and tags) than non-connected users. This similarity is the highest for directly connected users and decreases with the increase of distance between users. Among other interesting properties of information sharing is the finding that between-user similarity in social connections on the level of metadata and tags is much larger than similarity on the level of items. Overall, our findings support the feasibility of social network based recommender systems and offer some good hints to the prospective authors of these systems."

A popular way of associating such descriptions to content is tagging as can be found in popular sites such as Flickr (for images) or Delicious (bookmarks). This method allows users to associate tags to media, richly describing its content and may help in its retrieval at a later time. However, the process is mostly unstructured, leading to several problems. Nothing guarantees that the tags used are the most appropriate or the same tags are used in similar situations, making retrieval difficult.####Our approach relies on narrative-based interfaces which use stories as an organizing principle for tagging media. Given that humans have used stories to communicate since the dawn of time, narrative is a natural form of interaction. By inter-relating bits of information into a coherent whole, stories convey data in a rich, structured way. A study carried out with 40 users over a period of three months shows that users convey almost six times more information when using narratives to describe their media than what is typical of traditional methods. Furthermore, our pilot study saw narratives increasing tag reuse to 94%. Finally, other problems found in tagging such as synonyms and polysemy were notably absent from story-generated tags."

In this paper we study the problem of understanding the importance of messages in Twitter. We approach this problem in two stages. First, we perform an extensive characterization of a very large Twitter dataset which includes all users, social relations, and messages posted from the beginning of the service up to August 2009. We show evidence that information overload is present: users sometimes have to search through hundreds of messages to find those that are interesting to reply or retweet. We then identify factors that influence user response or retweet probability: previous responses to the same tweeter, the tweeter’s sending rate, the age and some basic text elements of the tweet. In our second stage, we show that some of these factors can be used to improve the presentation order of tweets to the user. First, by inspecting user activity over time, we construct a simple on-off model of user behavior that allows us to infer when a user is actively using Twitter. Then, we explore two methods from machine learning for ranking tweets: a Naive Bayes predictor and a Support Vector Machine classifier. We show that it is possible to reorder tweets to increase the fraction of replied or retweeted messages appearing in the first p positions of the list by as much as 50-60%."

This motivates the use of graph and Web based metrics for ranking storylets and some other tasks. A dataset, termed childif, based on printed books from three series popular with children and young adults and its characteristics are described.

Unfortunately, there is evidence that hashtag growth is not keeping pace with the growth of the overall real-time web. In a random sample of 3 million tweets, we find that only 10.2% contain at least one hashtag. Hence, in this paper we explore the possibility of predicting hashtags for un-annotated status updates. Toward this end, we propose and evaluate a graph-based prediction framework. Three of the unique features of the approach are: (i) a path aggregation technique for scoring the closeness of terms and hashtags in the graph; (ii) pivot term selection, for identifying high value terms in status updates; and (iii) a dynamic sliding window for recommending hashtags reflecting the current status of the real-time web. Experimentally we find encouraging results in comparison with Bayesian and data mining-based approaches."

We do this by defining a weighted cosine similarity proximity measure that takes into account both the clip vectors and the tag vectors.

Successful population modeling for crowds is critical for many services including location recommendation, traffic prediction, and advertising. However, crowd modeling is challenging since 1) user-contributed data in social media is noisy and oftentimes incomplete, in the sense that users only reveal when they join a crowd through posts but not when they depart; and 2) the size of short-lived crowds typically changes rapidly, growing and shrinking in sharp bursts. Toward robust population modeling, we first propose a duration model to predict the time users spend in a particular crowd. We propose a time-evolving population model for estimating the number of people departing a crowd, which enables the prediction of the total population remaining in a crowd. Based on these population models, we further describe an approach that allows us to predict the number of posts generated from a crowd. We validate the crowd models through extensive experiments over 22 million geo-location based check-ins and 120,000 event-related tweets."

In this paper, we analyze the behavior of mainstream media on Twitter and study how they exert their influence to shape public opinion during the UK’s 2010 General Election. We first propose an empirical measure to quantify mainstream media bias based on sentiment analysis and show that it correlates better with the actual political bias in the UK media than the pure quantitative measures based on media coverage of various political parties. We then compare the information diffusion patterns from different categories of sources. We found that while mainstream media is good at seeding prominent information cascades, its role in shaping public opinion is being challenged by journalists since tweets from them are more likely to be retweeted and they spread faster and have longer lifespan compared to tweets from mainstream media. Moreover, the political bias of the journalists is a good indicator of the actual election results."

It is a common observation that people tend to select friends with similar characteristics or individuals are likely to change their attributes to conform to their friends. In this measurement study we quantify the extension of this behavior on Facebook. We measure the probability with which a friend belonging to a particular group of friends will or will not comment on a post that has already received comments from other friends belonging/not belonging to his own circle of friends. To this end we collected an original data set of Facebook profiles of 50 volunteers. Our data analysis shows that Facebook users are influenced in their choice of posting comments on friends’ wall posts, based on whether or not they are acquainted with the people that left earlier comments. Identification of such behavioral nuances can be helpful in improving the user interface design of online social networks."

The analogy is not with the production of a literary work but with city planning, in particular Christopher Alexander’s iterative model for gradual change. In this model, there is no overall plan for the city; instead there are multiple local interventions guided by local insufficiencies and a library of spatial patterns. Applied to narrative hypertext this model would stress multiple local additions to a growing landscape of nodes and links. The results should provide more kinds of novelty and surprise than with conventional authoring software, but would have to deal with problems of narrative unity and closure."

In this paper, we analyze commonalities and differences between these groups, based on a set of 94,155 public user profiles. The results confirm that such subgroups can be recognized. Further, the average number of connections differs between groups, as a result of differences in intention for using social media. Similarly, within the groups, specific topics and resources are discussed and shared, and there are interesting differences in the tone and wording the group members use. These insights are relevant for interpreting results from social media analyses and can be used for identifying group-specific resources and communication practices that new members may want to know about."

Recently, rating prediction algorithms that are based on matrix factorisation have become increasingly popular, due to their high accuracy and scalability. However, these algorithms still deliver inaccurate rating predictions for new users, who submitted only a few ratings.####In this paper, we address the new user problem by introducing several extensions to the basic matrix factorisation algorithm, which take user attributes into account when generating rating predictions. We consider both demographic attributes, explicitly supplied by users, and attributes inferred from user-generated texts. Our results show that employing our text-based user attributes yields personalised rating predictions that are more accurate than our baselines, while not requiring users to explicitly supply any information about themselves and their preferences."

While these approaches provide a solution for developing new websites, they go past the plethora of existing websites. To address this issue, we present an approach for enhancing existing websites on-the-fly with context-aware features.

We examine how different types of individual behavior affect the decisions of friends in a network. We begin with the problem of detecting social influence in a social system. Then we investigate the causality between individual behavior and social influence by observing the diffusion of an innovation among social peers. Are more active users more influential? Are more credible users more influential? Bridging this gap and finding points where the macroscopic and microscopic worlds converge contributes to better interpretations of the mechanisms of spreading of ideas and behaviors in networks and offer design opportunities for online social systems."

Both are language-neutral and noise-tolerant, guaranteeing high effectiveness and robustness in the settings we are considering. To ensure our approach can be integrated into practical applications with large volumes of data, we also aim at enhancing its time efficiency: we propose alternative sets of features with low extraction cost, explore dimensionality reduction and discretization techniques and experiment with multiple classification algorithms. We then evaluate our methods over a large, real-world data set extracted from Twitter, with the outcomes indicating significant improvements over the traditional techniques."

Exchanging user information across heterogeneous systems has many benefits, particularly in enhancing the quality and quantity of user information available for personalization. One common approach to user model interoperability is the use of mapping tools to manually build rich executable mappings between user models. A key problem with existing approaches is that the mapping tools are often too generic for these specialized tasks and do not provide any support to an administrator mapping in a specific domain such as user models. This paper presents a novel approach to user model interoperability which lowers the complexity and provides support to administrators in completing user model mappings. The domain-aware approach to user model interoperability incorporates interchangeable domain knowledge directly into the integration tools. This approach was implemented in a system called FUMES which is a mapping creation and execution environment that includes two domain-aware mechanisms; a canonical user model and user model mapping types. FUMES was deployed in an integration of existing user models and the domain-aware approach was then evaluated in a user study. The evaluation consisted of a direct comparison with a generic approach to user model interoperability which was applied using the commercial mapping tool, Altova Mapforce. The results of this evaluation demonstrate improvements in mapping accuracy and usability when using the domain-aware approach compared to the generic mapping approach."

In this work, we model users’ preferences, and we match their actual transport use. We use data coming from a mobility platform developed for mobile devices, whose aim is to understand the value of users’ travel time. Our first goal is to characterize the perception that users have of their mobility by analyzing their general preferences expressed before their travel time. Our approach combines dimensionality reduction and clustering techniques to provide interpretable profiles of users. Then, we perform the same task after monitoring users’ travels by doing a matching between users’ preferences and their actual behavior. Our results show that there are substantial differences between users’ perception of their mobility and their actual behavior: users overestimate their preferences for specific mobility modes, that in general, yield a lower return in terms of the worthwhileness of their trip."

That is, even though the online advertising business model has is very successful, nowadays, rising societal concerns regarding the ethics and extent to which such algorithms agree with the laws of different countries are also present. Motivated by the dichotomy above, we here explore how targeted video-ads meet the regulatory policies regarding children advertising in Brazil and Canada. To perform our study, we create synthetic user personas that watch YouTube videos daily. Our personas are tailored to stream children’s content while controlling for several variables (e.g., gender, country, and type of content streamed). With the data gathered, our analyses reveal statistical evidence of algorithmic targeting in videos geared towards children. Also, some of the advertised products (e.g., alcoholic beverages and fast-food) go directly against the regulations of the studied countries. With advertisements being matched to users by machine learning algorithms, it is impossible to state whether regulations are not followed on purpose (e.g., advertisers gaming the system). Nevertheless, our findings and discussion do raise a flag that regulations may not be sufficient, and content providers may still need to audit systems to meet the regulations."

More recently, a few projects demonstrated that personalising the process of information exploration with models of user interests can add value to information exploration systems. However, the current model-based information exploration interfaces are very sophisticated and focus on highly experienced users.

This paper primarily focuses on educational concerns related to that approach: I first review discussions about the challenges surrounding game-based learning approaches and claim that some common points of skepticism in these discussions actually highlight the effectiveness of games for learning about queer representation. I also suggest that, as a genre, choice-based interactive fiction is ideal for exploratory learning about queer representation in comparison to other kinds of games. I then analyze educational uses of video game modification, noting that one of the most common approaches is educators modifying popular games for the classroom. I claim that approach could work especially well as a way to explore problems with representation in video games. I close the article with a short discussion about expanding upon this approach by building an easily-modifiable interactive fiction game to address issues with portrayals of queerness in mainstream games, a method I examine more fully in my PhD dissertation and through an associated digital game prototype. Overall, I argue that interactive fiction works are very well-suited to dealing with issues of representation and that modifiable interactive fiction games are an effective way to learn more about problems with representation in video games."

The visual tags could also be used in the moderate cold start situation when the new video might have been annotated with few tags.

Many users want to gain followers to increase the visibility and reach of their profiles to wide audiences. This has provoked several blackmarket services to garner huge attention by providing artificial followers via the network of agreeable and compromised accounts in a collusive manner. Their activity is difficult to detect as the blackmarket services shape their behavior in such a way that users who are part of these services disguise themselves as genuine users. In this paper, we propose DECIFE, a framework to detect collusive users involved in producing 'following' activities through blackmarket services with the intention to gain collusive followers in return. We first construct a heterogeneous user-tweet-topic network to leverage the follower/followee relationships and linguistic properties of a user. The heterogeneous network is then decomposed to form four different subgraphs that capture the semantic relations between the users. An attention-based subgraph aggregation network is proposed to learn and combine the node representations from each subgraph. The combined representation is finally passed on to a hypersphere learning objective to detect collusive users. Comprehensive experiments on our curated dataset are conducted to validate the effectiveness of DECIFE by comparing it with other state-of-the-art approaches. To our knowledge, this is the first attempt to detect collusive users involved in blackmarket 'following services' on Twitter."

In this work, we study adversarial attacks that are uninformed, where an attacker only has access to the graph structure, but no information about node attributes. Here the attacker aims to exploit structural knowledge and assumptions, which GNN models make about graph data. In particular, literature has shown that structural node centrality and similarity have a strong influence on learning with GNNs. Therefore, we study the impact of centrality and similarity on adversarial attacks on GNNs. We demonstrate that attackers can exploit this information to decrease the performance of GNNs by focusing on injecting links between nodes of low similarity and, surprisingly, low centrality. We show that structure-based uninformed attacks can approach the performance of informed attacks, while being computationally more efficient. With our paper, we present a new attack strategy on GNNs that we refer to as Structack. Structack can successfully manipulate the performance of GNNs with very limited information while operating under tight computational constraints. Our work contributes towards building more robust machine learning approaches on graphs."

In recent years, engineering diversity advocates have taken to social media platforms to raise awareness of the issue and redress this problem. A recurring challenge for their initiatives though is attracting and mobilizing participants efficiently. For a successful mobilization campaign, organizers need real-time information about their users and also need to understand what messaging works to attract and mobilize them. We hypothesize that participants in any given campaign related to engineering diversity will also be interested in other campaigns related to that issue. Furthermore, since the primary signal for a social media campaign is a hashtag, by using clustering patterns of various co-occurring hashtags along with relevant topics and relatable sentiments, we can better understand participation and also mobilize users for the target campaign.####To empirically examine our hypothesis, we study two diversity hashtag activism campaigns on Twitter (#ILookLikeAnEngineer and #WomenInEngineering) using a real-time predictive analytics framework. We design and evaluate the framework with a set of novel features that uses retweetability as an indicator of participation.####Our result analysis for topical features found that monetary gain and advertisement-oriented content were less likely to be propagated in the campaigns whereas messaging aligned directly with the issue at hand such as breaking stereotypes in engineering was deemed more retweetable and engaging.####In terms of sentiments, informal tone in the messages were considered desirable whereas short-form messaging were not very popular in either movements.####These analytical insights can inform activists in effective resource mobilization through message content design, in order to expand the reach of an activism campaign. Our work shows how data-driven techniques can assist in increasing the participation of women in engineering education and the workforce."

In contrast, we propose CrisisBERT, an end-to-end transformer-based model for two crisis classification tasks, namely crisis detection and crisis recognition, which shows promising results across accuracy and F1 scores. The proposed CrisisBERT model demonstrates superior robustness over various benchmarks, and it includes only marginal performance compromise while extending from 6 to 36 events with a mere 51.4% additional data points. We also propose Crisis2Vec, an attention-based, document-level contextual embedding architecture, for crisis embedding, which achieves better performance than conventional crisis embedding methods such as Word2Vec and GloVe."

However, it is currently unclear what personal and contextual factors affect users' privacy concerns about various types of personal information. This paper studies the effect of users' personality traits and preference scenarios ---having a majority or minority preference--- on their privacy concerns regarding location and emotion information. To create natural scenarios of group decision-making where users can control the amount of information disclosed, we develop TouryBot, a chat-bot agent that generates natural language explanations to help group members explain their arguments for suggestions to the group in the tourism domain. We conducted a user study in which we instructed 541 participants to convince the group to either visit or skip a recommended place. Our results show that users generally have a larger concern regarding the disclosure of emotion compared to location information. However, we found no evidence that personality traits or preference scenarios affect privacy concerns in our task. Further analyses revealed that task design (i.e., the pressure on users to convince the group) had an effect on participants' emotion-related privacy concerns. Our study also highlights the utility of providing users with the option of partial disclosure of personal information, which appeared to be popular among the participants."

Prior research shows that inexperienced requesters fail to write clear and complete task descriptions which directly leads to low quality submissions from workers. By complementing existing works that have aimed to address this challenge, in this paper we study whether clarity flaws in task descriptions can be identified automatically using natural language processing methods. We identify and synthesize seven clarity flaws in task descriptions that are grounded in relevant literature. We build both BERT-based and feature-based binary classifiers, in order to study the extent to which clarity flaws in task descriptions can be computationally assessed, and understand textual properties of descriptions that affect task clarity. Through a crowdsourced study, we collect annotations of clarity flaws in 1332 real task descriptions. Using this dataset, we evaluate several configurations of the classifiers. Our results indicate that nearly all the clarity flaws in task descriptions can be assessed reasonably by the classifiers. We found that the content, style, and readability of tasks descriptions are particularly important in shaping their clarity. This work has important implications on the design of tools to help requesters in improving task clarity on crowdsourcing platforms. Flaw-specific properties can provide for valuable guidance in improving task descriptions.####"

Since blind users rely on screen reader audio, interacting with online videos can be challenging due to the screen reader audio interfering with the video sounds. Existing solutions to address this interference problem are predominantly designed for desktop scenarios, where special keyboard or mouse actions are supported to facilitate 'silent' and direct access to various video controls such as play, pause, and progress bar. As these solutions are not transferable to smartphones, suitable alternatives are desired. In this regard, we explore the potential of motion gestures in smartphones as an effective and convenient method for blind screen reader users to interact with online videos. Specifically, we designed and developed YouTilt, an Android application that enables screen reader users to exploit an assortment of motion gestures to access and manipulate various video controls. We then conducted a user study with 10 blind participants to investigate whether blind users can leverage YouTilt to properly execute motion gestures for video-interaction tasks while simultaneously listening to video sounds. Analysis of the study data showed a significant improvement in usability by as much as 43.3% (avg.) with YouTilt compared to that with default screen reader, and overall a positive attitude and acceptance towards motion gesture-based video interaction."

Therefore, distinguishing individuals out of all accounts is crucial when we conduct research such as understanding human behavior based on data retrieved from those platforms. In this paper, we propose a language-independent approach for distinguishing individuals from non-individuals with the focus on leveraging their profile images, which has not been explored in previous studies.

This is quite surprising given that even before the existence of the computer, Information Science visionaries such as Vannevar Bush described more powerful information management solutions. We therefore aim to improve the way information is managed in modern desktop environments by embedding a hypermedia engine offering rich hypermedia and cross-media concepts at the level of an operating system. We discuss the resource-selector-link (RSL) hypermedia metamodel as a candidate for realising such a general hypermedia engine and highlight its flexibility based on a number of domain-specific applications that have been developed over the last two decades. The underlying content repository will no longer rely on monolithic files, but rather contain a user's data in the form of content fragments, such as snippets of text or images, which are structurally linked to form the corresponding documents, and can be reused in other documents or even shared across computers. By increasing the scope to a system-wide hypermedia engine, we have to deal with fundamental challenges related to granularity, interoperability or context resolving. We strongly believe that computing technology has evolved enough to revisit and address these challenges, laying the foundation for a wide range of innovative use cases for efficiently managing cross-media content in modern desktop environments."

Our goal is to show how these social traces (signals) can play a vital role in improving Arabic Facebook search. Firstly, we identify polarities (positive or negative) carried by the textual signals (e.g. comments) and non-textual ones (e.g. the reactions love and sad) for a given Facebook post. Therefore, the polarity of each comment expressed on a given Facebook post, is estimated on the basis of a neural sentiment model in Arabic language. Secondly, we group signals according to their complementarity using features selection algorithms. Thirdly, we apply learning to rank (LTR) algorithms to re-rank Facebook search results based on the selected groups of signals. Finally, experiments are carried out on 13,500 Facebook posts, collected from 45 topics in Arabic language. Experiments results reveal that Random Forests combined with ReliefFAttributeEval (RLF) was the most effective LTR approach for this task."

These stories are selected by an algorithm that chooses from hundreds of thousands of articles published by thousands of news publishers. In our previous work, we identified 56 news sources that contributed 2/3 of all Top stories for 30 political candidates running in the primaries of 2020 US Presidential Election. In this paper, we survey US voters to elicit their familiarity and trust with these 56 news outlets. We find that some of the most frequent outlets are not familiar to all voters (e.g. The Hill or Politico), or particularly trusted by voters of any political stripes (e.g. Washington Examiner or The Daily Beast). Why then, are such sources shown so frequently in Top stories? We theorize that Google is sampling news articles from sources with different political leanings to offer a balanced coverage. This is reminiscent of the so-called “fairness doctrine” (1949-1987) policy in the United States that required broadcasters (radio or TV stations) to air contrasting views about controversial matters. Because there are fewer right-leaning publications than center or left-leaning ones, in order to maintain this “fair” balance, hyper-partisan far-right news sources of low trust receive more visibility than some news sources that are more familiar to and trusted by the public."

In this paper, we consider the task of unsupervised fake news detection, which considers fake news detection in the absence of labelled historical data. We develop GTUT, a graph-based approach for the task which operates in three phases. Starting off with identifying a seed set of fake and legitimate articles exploiting high-level observations on inter-user behavior in fake news propagation, it progressively expands the labelling to all articles in the dataset. Our technique draws upon graph-based methods such as biclique identification, graph-based feature vector learning and label spreading.

Generally, all investigated aggregation strategies performed well in terms of perceived individual and group satisfaction and perceived fairness.

In this paper, we study this problem by investigating a large collection of such narratives from the movie domain. We start by empirically analyzing a dataset containing free-text narratives representing movie suggestion requests from reddit users as well as community suggestions to those requests. We find that community suggestions are frequently more diverse than requests, making a recommendation task a challenging one. In a prediction experiment, we use embedding algorithms to assess the importance of request features including movie descriptions, genres, and plot keywords, by computing recommendations. Our findings suggest that, in our dataset, positive movies and keywords have the strongest, whereas negative movie features have the weakest predictive power.

In countries such as the UK, Twitter has become the platform of choice, with over 85% (553 of 650) of the Members of Parliament (MPs) having an active online presence. Whereas this has allowed ordinary citizens unprecedented and immediate access to their elected representatives, it has also led to serious concerns about online hate towards MPs. This work attempts to shed light on the problem using a dataset of conversations between MPs and non-MPs over a two month period. Deviating from other approaches in the literature, our data captures entire threads of conversations between Twitter handles of MPs and citizens in order to provide a full context for content that may be flagged as 'hate'. By combining widely-used hate speech detection tools trained on several widely available datasets, we analyse 2.5 million tweets to identify hate speech against MPs and we characterise hate across multiple dimensions of time, topics and MPs' demographics. We find that MPs are subject to intense 'pile on' hate by citizens whereby they get more hate when they are already busy with a high volume of mentions regarding some event or situation. We also show that hate is more dense with regard to certain topics and that MPs who have an ethnic minority background and those holding positions in Government receive more hate than other MPs. We find evidence of citizens expressing negative sentiments while engaging in cross-party conversations, with supporters of one party (e.g. Labour) directing hate against MPs of another party (e.g. Conservative)."

The mapping between digital and material artefacts outlines a theory of manuscript “transmediations” identifying where and how manuscripts cues are reflected in digital technologies.

Building on game scholarship that recognizes 'immersion' as a “double-axis of incorporation” [8] consisting of a “complex interplay of actual and virtual worlds as perceived through a dually embodied player” [26,p. 73], we can see how these games achieve powerful moments of coattention through outmersive game design-deliberately alienating the player from an embodied avatar experience. Outmersion,a term coined by Gonzalo Frasca, offers a broader categorization for games that procedurally engender “critical distance” by directing player attention to and outside of the game itself [16]. This article uses close-play to explore how the characters of Jesse Faden in Control and Senua in Hellblade make use of the 'coinhabited avatar' trope-in which the avatar is possessed by non-player entities. This article identifies shared outcomes in the outmersive design of these characters, namely that they: 1) directly invoked the player 2) complicated the player's place in the avatar body 3) deceived the player 4) took agency from the player and 5) referenced game structures directly. Through outmersion, these games created provocative moments of player attention and reflection, simultaneously interrogating assumptions of power, rules, and embodiment. This article advocates for further exploration of outmersive game and interactive narrative design to challenge dominant presumptions about player-avatar interactions."

Now, more than ever, people express themselves online while mainstream news agencies attempt to utilize the power of the Internet to spread their articles as much as possible. To grasp the political coexistence of mainstream media and online social media, in this paper, we analyze these two sources of information in the context of the U.S. 2020 presidential election. In particular, we collected data during the 2020 Democratic Party presidential primaries pertaining to the candidates, and, by analyzing this data, we highlight similarities and differences between these two main types of sources, detect the potential impact they have on each other, and understand how this impact relationship can change over time."

The current literature on hate speech detection leverages primarily the textual content to find hateful posts and subsequently identify hateful users. However, this methodology disregards the social connections between users. In this paper, we run a detailed exploration of the problem space and investigate an array of models ranging from purely textual to graph based to finally semi-supervised techniques using Graph Neural Networks (GNN) that utilize both textual and graph-based features. We run exhaustive experiments on two datasets -- Gab, which is loosely moderated and Twitter, which is strictly moderated. Overall the AGNN model achieves 0.791 macro F1-score on the Gab dataset and 0.780 macro F1-score on the Twitter dataset using only 5% of the labeled instances, considerably outperforming all the other models including the fully supervised ones. We perform detailed error analysis on the best performing text and graph based models and observe that hateful users have unique network neighborhood signatures and the AGNN model benefits by paying attention to these signatures. This property, as we observe, also allows the model to generalize well across platforms in a zero-shot setting. Lastly, we utilize the best performing GNN model to analyze the evolution of hateful users and their targets over time in Gab."

Known-item needs form a particular type of information need and occur when a user has a limited but concrete description of an existing object and would like to (re-)find it. Most studies of know-item needs have focused on the short query representations of these needs as they occur in search engine logs. In this article, we focus on richer, more complex known-item need representations posted to six dedicated Reddit discussion forums in the casual leisure domain. An analysis of 462 known-item requests from these subreddits revealed 33 different relevance aspects of items in a variety of different domains. Some of these aspects are highly domain-specific, while others are broadly applicable across domains. The domain %of the item sought also has a strong influence on the length of the known-item requests. Our findings can be used to prioritize efforts to help existing search engines better support known-item needs, both by highlighting which aspects are easier to classify automatically and by determining which information sources should be added to a search engine's index."

I demonstrate that all three of these works use Scalar to create genre-bending texts that build on and subvert the technological affordances as well as the contextual connotations that Scalar provides. The Scalar Conspiracy parodies the counter-intuitive user interface elements by making the reader investigate the text's different hidden messages. daddylabyrinth: a digital lyric memoir destabilizes the genre of the (auto)biography by promoting documentation and research while continuously showing how these processes fall short during the writing and reading process. Redshift & Portalmetal favors experience over documentation to create a work that is both immersive and theory-building. These Scalar fictions are characterized by the premise that the platform's academic context strengthens the narrative. Researching the multimodality and academic context as integral parts of the narrative structure opens up the opportunity to reckon with the platform-specificity across genres."

A deeper understanding of these users can contribute to the development of a framework for identifying users who are likely to spread fake news. In this work, we study the characteristics and motivational factors of fake news spreaders on social media with input from psychological theories and behavioral studies. We then perform a series of experiments to determine if fake news spreaders can be found to exhibit different characteristics than other users. Further, we investigate our findings by testing whether the characteristics we observe amongst fake news spreaders in our experiments can be applied to the detection of fake news spreaders in a real social media environment."

Specifically, we seek to determine (i) whether an emoji is sufficient to contextualize expressions of grief; (ii) which emojis most accurately represent mourning; (iii) whether only words are used to contextualize mourning; (iv) which words are used to characterize mourning in tweets; and, (v) if there are differences in the expression of mourning in different languages. For this, we use a multi-stage method to conduct a comprehensive analysis of the manifestations of grieving behavior on Twitter, and created machine learning models to classify expressions of mourning in tweets. The main contributions from this work are (1) a gold standard of manually annotated mourning tweets; (2) classification models produced using machine learning ensemble methods and BERT contextual embeddings; and, (3) an extensive analysis of our findings opening up opportunities for new research. The results of this paper reveal emojis alone are insufficient for identifying expressions of mourning in tweets, and the combination of both emojis and words is the most effective strategy for contextualizing mourning online -- the models achieved the 84.8%-97% F1 score in all datasets. Although words alone are capable of characterizing mourning contexts correctly, the English vocabulary is limited, and the contribution of RIP - the abbreviation for “rest in peace” - is highly decisive. Our results have also shown that the most relevant emojis for this context were emotional ones, such as \includegraphics[width=1em]twitter_brokenheart.png, and emojis are used in a uniform fashion in both Spanish and English."

Some sources may be incomplete, less reliable or less relevant for the purpose of recommendation. Thus, each content source or attribute possess different level of informativeness, which should be taken into consideration during the process of recommendation. In this paper, we propose a multiple content alignments extension to the Bayesian Personalized Ranking Matrix Factorization (BPR-MCA). The proposed method incorporates multiple sources of content information in the form of user-to-user or object-to-object similarity matrices and aligns users’ and items’latent factors ac-cording to these similarities. During the training phase, BPR-MCA also learns the relevance weight of each similarity matrix. BPR-MCA was evaluated on the MovieLens 1M dataset, extended by the content information from IMDB, DBTropes and ZIP code statistics. The experiment shows that BPR-MCA can help to significantly improve recommendation w.r.t. nDCG and AUPR over standard BPR under several cold-start scenarios."

Traditional network embedding methods are often inefficient in capturing - (i) the latent relationship when the network is sparse (the network sparsity problem), and (ii) the local and global neighborhood structure of vertices (structure preserving problem).####We propose SENA, a structural embedding and network augmentation framework for social network analysis. Unlike other embedding methods which only generate vertex features, SENA generates features for both vertices and relations (edges) by minimizing a well-designed objective function composed of a loss function and a regularization. The loss function reduces the network-sparsity problem by learning from both the edges present (true edges) and absent (false edges) in the network; whereas the regularization term preserves the structural properties of the network by efficiently considering - (i) the local neighborhood of vertices and edges, and (ii) the network spectra, i.e., eigenvectors of a symmetric matrix representing the network.####We compare SENA with four baseline network embedding methods, namely DeepWalk, SE, SME and TransE. We demonstrate the efficacy of SENA through a task-based evaluation setting on different real-world networks. We consider the state-of-the-art algorithms for (i) community detection, (ii) link prediction and (iii) knowledge graph query answering, and show that with SENA’s representation, these algorithms achieve up to 10%, 9% and (surprisingly) 108% higher accuracy respectively compared to the best baseline embedding methods."

We leveraged text analysis to automatically classify over 32,000 posts shared in these hyper-local forums. Our findings suggest that neighbors use the forums largely for social capital mobilization, requesting both active and passive actions.

Despite the initial enthusiasm of the first wave of MOOCs and the subsequent research efforts, MOOCs today suffer from retention issues: many MOOC learners start but do not finish. A main culprit is the lack of oversight and directions: learners need to be skilled in self-regulated learning to monitor themselves and their progress, keep their focus and plan their learning. Many learners lack such skills and as a consequence do not succeed in their chosen MOOC. Many of today’s MOOCs are centered around video lectures, which provide ample opportunities for learners to become distracted and lose their attention without realizing it. If we were able to detect learners’ loss of attention in real-time, we would be able to intervene and ideally return learners’ attention to the video. This is the scenario we investigate: we designed a privacy-aware system (IntelliEye) that makes use of learners’ Webcam feeds to determine—in real-time—when they no longer pay attention to the lecture videos. IntelliEye makes learners aware of their attention loss via visual and auditory cues. We deployed IntelliEye in a MOOC across a period of 74 days and explore to what extent MOOC learners accept it as part of their learning and to what extent it influences learners’ behaviour.

This suggests that penny auction sites are vulnerable to modeling and adversarial attacks."

In this work, we propose a new adversarial attack specialized for social media data. We further provide a principled way to assess effectiveness of anonymizing different aspects of social media data.

However, recent events in our society proved that they can have important effects on real life as well. Bots have in fact become one of the key tools for disseminating information through online social networks (OSNs), influencing their members and eventually changing their opinions. With a focus on classification, social bot detection has lately emerged as a major topic in OSN analysis; nevertheless more research is needed to enhance our understanding of such automated behaviors, particularly to unveil the characteristics that better differentiate legitimate accounts from bots. We argue that this demands for learning behavioral models that should be trained using a large and heterogeneous set of behavioral features, so to detect and characterize OSN accounts according to their status as bots. Within this view, in this work we push forward research on bot analysis by proposing a machine-learning framework for identifying and ranking OSN accounts based on their degree of bot relevance. Our framework exploits the most known existing methods on bot detection for enhanced feature extraction, and state-of-the-art learning-to-rank methods, using different optimization and evaluation criteria. Results obtained on Twitter data show the significance and effectiveness of our approach in detecting and ranking bot accounts."

This rigidity is unfortunate since it does not allow the integration of the multitude of signals informing effective stance detection. We propose the SCSD model, or Sequential Community-based Stance Detection model, a semi-supervised ensemble algorithm which considers these signals by modeling them as a multi-layer graph representing proximities between profiles. We use a handful of seed profiles, for whom we know the stance, to classify the rest of the profiles by exploiting like-minded communities. These communities represent profiles close enough to assume they share a similar stance on a given subject. Using datasets from two different social platforms, containing two to five stances, we show that by combining several types of proximity we can achieve excellent results. Moreover, we compare the proximities to find those which convey useful information in term of stance detection."

In this paper, we propose a novel framework which first assigns tweets into different situational classes and then summarize those tweets. In the summarization phase, we propose a two stage summarization framework which first extracts a set of important tweets from the whole set of information through an Integer-linear programming (ILP) based optimization technique and then follows a word graph and content word based abstractive summarization technique to produce the final summary. Our method is time and memory efficient and outperforms the baseline in terms of quality, coverage of events, locations et al., effectiveness, and utility in disaster scenarios."

Yet several key issues still remain unresolved, including optimal handling of cold starts and how best to maintain user-privacy within that context. Recent work has demonstrated a potentially fruitful line of attack in the form of cross-system user modelling, which uses features generated from one domain to bootstrap recommendations in another. In this paper we evidence the effectiveness of this approach through direct real-world user feedback, deconstructing a cross-system news recommendation service where user models are generated via social media data. It is shown that even when a relatively naive vector-space approach is used, it is possible to automatically generate user-models that provide statistically superior performance than when items are explicitly filtered based on a user’s self-declared preferences. Detailed qualitative analysis of why such effects occur indicate that different models are capturing widely different areas within a user’s preference space, and that hybrid models represent fertile ground for future research."

Following the theory for meaningful learning, according to which new knowledge is developed starting from familiar entities (anchors) and expanding to new and unfamiliar entities, we propose here an approach to identify knowledge anchors in a data graph. Our approach is underpinned by the Cognitive Science notion of basic level objects in domain taxonomies. Several metrics for extracting knowledge anchors in a data graph, and the corresponding algorithms, are presented.

The value of substitution depends on how well the synonyms preserve semantic meaning, as any attrition in meaning can result in semantic drift of query results. Many synonyms are not synonyms in the traditional, thesaurus sense, but are semantic associations discovered automatically from online data, with the risk of semantic drift in substitution. This discovery of synonyms or other semantic associations arises from different methods applied over web search logs, and in this paper we review the candidate synonym pairs of words or phrases generated from three different methods applied over the same web search logs. The suitability of the candidate synonym pairs for the purpose of query substitution is evaluated in an experiment where 68 subjects assessed the search results generated by both the original query and the substituted query. It was found that two of the discovery methods returned significantly worse results with the substitution than were returned by the original query for the majority of queries, with only around 20-22% of substituted queries generating either improved or equally-relevant results. The third method however returned a very similar level of superior results as the original query, and saw over 71% of substituted queries generating either improved or equally-relevant results. These results indicate that even when candidate synonym pairs are confirmed as being semantically associated using other methods, they still may not be suitable for query substitution, depending on the method of synonym discovery."

For each category, we build a prediction model for consumption decision based on the derived personality features. We experiment with our prediction models under different conditions segmented by both situational factors. Our results suggest that personality’s decisive power on consumer behavior varies significantly among different income levels, but non-significantly between consumer needs. Together, income and needs also have significant effect on the association between individual’s personality and consumption behavior.

In this paper, we tackle this challenge, by identifying coherent topic-dependent user groups, linking those who generate the content (creators) and those who spread this content, e.g., by retweeting/reposting it (distributors).

However, visualizations have shown to be effective in dealing with huge datasets: because they are grounded on visual cognition, people understand them and can naturally perform visual operations such as clustering, filtering and comparing quantities. But, creating appropriate visual representations of data is also challenging: it requires domain knowledge, understanding of the data, and knowledge about task and user preferences. To tackle this issue, we have developed a recommender system that generates visualizations based on (i) a set of visual cognition rules/guidelines, and (ii) filters a subset considering user preferences. A user places interests on several aspects of a visualization, the task or problem it helps to solve, the operations it permits, or the features of the dataset it represents. This paper concentrates on characterizing user preferences, in particular: i) the sources of information used to describe the visualizations, the content descriptors respectively, and ii) the methods to produce the most suitable recommendations thereby. We consider three sources corresponding to different aspects of interest: a title that describes the chart, a question that can be answered with the chart (and the answer), and a collection of tags describing features of the chart. We investigate user-provided input based on these sources collected with a crowd-sourced study. Firstly, information-theoretic measures are applied to each source to determine the efficiency of the input in describing user preferences and visualization contents (user and item models). Secondly, the practicability of each input is evaluated with content-based recommender system. The overall methodology and results contribute methods for design and analysis of visual recommender systems. The findings in this paper highlight the inputs which can (i) effectively encode the content of the visualizations and user’s visual preferences/interest, and (ii) are more valuable for recommending personalized visualizations."

The need is to develop algorithms that can adapt across domains by leveraging labeled data from source domain(s) and efficiently perform the task in the unlabeled target domain. Towards this, we present a novel two-stage neural network learning algorithm for domain adaptation which learns a multi-part hidden layer where individual parts contribute differently to the tasks in source and target domains. The multiple parts of the representation (i.e. hidden layer) are learned while being cognizant of what characteristics to transfer across domains and what to preserve within domains for enhanced performance. The first stage embroils around learning a two-part representation i.e. source specific and common representations in a manner such that the former do not detract the ability of the later to represent the target domain. In the second stage, the generalized common representation is further iteratively extended with discriminating target specific characteristics to adapt to the target domain. We empirically demonstrate that the learned representations, in different arrangements, outperform existing domain adaptation algorithms in the source classification as well as the cross-domain classification tasks on the user generated content from different domains on the web."

Thus, structural skeleton of such documents plays important role in determining the semantics of the data content. Presence of structure sometimes allows us to write simple rules to extract such information, but it may not be always possible due to flexibility in the structure and the frequency with which such structures are altered. In this paper, we propose a joint modeling of text and the associated structure to effectively capture the semantics of the semi-structure documents. The model simultaneously learns the dense continuous representation for word tokens and the structure associated with them. We utilize the context of structures for projection such that similar structures containing semantically similar topics are close to each other in vector space. We explore two semantic text mining tasks over web data to test the effectiveness of our representation viz., document similarity, and table semantic component identification. In context of traditional rule-based approaches, both these tasks demand rich, domain-specific knowledge sources, homogeneous schema for the documents, and rules that capture the semantics. On the other hand, our approach is unsupervised and resource conscious in nature. Despite of working without knowledge resources and large training data, it performs at par with state-of-the-art rule based and other unsupervised approaches."

This type of engagement not only leads to incidental learning of participants but also indicates the added value of corpus enrichment via different types of annotations undertaken by users generating so-called smart texts. Our work focuses on the continuous task of adding new layers of annotation to Classical Literature. We aim to provide more extensive tools for readers of smart texts, enhancing their reading comprehension and at the same time empowering the language learning by introducing intellectual tasks, i.e., linking, tagging, and disambiguation. The current study adds a new mode of annotation-audio annotations-to the extensively annotated corpus of poetry by the Persian poet Hafiz. By proposing tasks with three different difficulty levels, we estimate the users’ ability of providing correct annotations in order to rate their answers in further stages of the project, where no ground truth data is available. While proficiency in Persian is beneficial, annotators with no knowledge of Persian are also able to add annotations to the corpus."

This study analyzes how hypermedia structures can facilitate students’ critical reflection on their papers by using multimodal resources. By converging academic writing, knowledge representation, and multimedia resources, we designed a hypermedia system that enables the visualization and representation of students’ papers using text, images, audio, hyperlinks, and videos. To test the system, we conducted a pilot study in which we instructed 160 undergraduate students to write a paper in the following three-step exercise: First, students submitted an initial draft of their papers. Then, they used the system to translate the papers’ content into different multimodal resources. Finally, they rewrote their papers with insights gained from the process. In a concluding survey, students reported that translating text to multimodal resources deepened their understanding of their papers’ content and improved their topic organization."

Recent research efforts have targeted the optimization of web search to satisfy learning related needs. However, there is little known about how one’s search interactions differ across varying cognitive levels that correspond to one’s learning. In this paper, we address this knowledge gap by investigating how the search interactions of 150 users vary across 6 search tasks corresponding to distinct cognitive levels. We also analyze how users’ knowledge gain varies across the cognitive levels. Our findings suggest that the cognitive learning level of a user in a search session has a significant impact on the user’s search behavior and knowledge gain. Estimating the cognitive level of users during their interactions with search systems will allow us to construct and improve learning experiences for the users. For example, learners can be served content that corresponds to their current cognitive level within their learning process."

This paper proposes an analysis of the diversity of the navigation of users inside a website through the analysis of server log files. The methodology, guided and illustrated by a case study, but easily applicable to other cases, establishes relations between types of users’ behavior, site structure, and diversity of web browsing. Using the navigation paths of sessions reconstructed from the log file, the proposed methodology offers three main insights: 1) it reveals diversification patterns associated with the page network structure, 2) it relates human browsing characteristics (such as multi-tabbing or click frequency) with the degree of diversity, and 3) it helps identifying diversification patterns specific to subsets of users. These results are in turn useful in the analysis of recommender systems and in the design of websites when there are diversity-related goals or constrains."

For example, e-commerce portals can be adjusted to strengthen customer engagement or information sites can be optimized to improve the availability of relevant content to the user. In web navigation, the users goal and whether she reached it, is typically unknown. This makes navigation games particularly interesting to researchers, since they capture human navigation towards a known goal and allowbuilding labelled datasets suitable for supervised machine learning models. In this work, we show that a recurrent neural network model can predict game success from a partial click trail without knowledge of the users navigation goal. We evaluate our approach on data from WikiSpeedia and WikiGame, two well known navigation games and achieve an AUC of 86% and 90%, respectively. Furthermore, we show that our model outperforms a baseline that leverages the navigation goal on the WikiSpeedia dataset. A detailed analysis of both datasets with regards to structural and content related properties reveals significant differences in navigation behaviour, which confirms the applicability of our approach to different settings."

This paper presents a comprehensive study that aims to understand worker moods and how workers react to rejections in microtask crowdsourcing. We experimentally investigate the effect of the mood of workers on their performance, and the interaction of their moods with their reactions to rejection. Finally, we explore techniques such as presenting social comparative explanations to foster positive reactions to rejection. We found that workers in pleasant moods significantly outperform those in unpleasant moods.

We used results from this study to design a prototype prediction game, Fantasy Climate, which helps players move from intuitions and advice to consuming news and analyzing data by supporting a variety of activities essential to gameplay.

Experiment 1 focused on the effect of question, answer, and answer’s opinion. Experiment 2 focused on the effect of the alternative question, i.e., a question related to the solution that can achieve the same goal as a query. The results revealed the following. (i) Participants issued fewer queries and spent less time on a SERP when People also ask were presented. (ii) Participants were less likely to interact with a SERP when they first encounter a belief-inconsistent answer. (iii) We could not confirm the effect of People also ask on beliefs at the current state. The findings suggest that People also ask might not help mitigate confirmation bias as participants are likely to spend less effort on the search process (i.e., issue fewer queries) when they first encounter a belief-inconsistent answer unlike when they encounter a belief-inconsistent document within the search results. An additional experiment is required to validate that participants who first encounter a belief-inconsistent answer are more likely to alter their beliefs as the number of such participants was inadequate."

This matters as different communities are now exploring hypertext, interactive fiction, electronic literature, and narrative games from different perspectives - but lack a common critical vocabulary or shared body of work with which they can communicate. In this paper I attempt to deconstruct the relationship between literary hypertext and narrative games. I do this through two lenses. Firstly, by looking at Hypertext as Games; with a specific set of mechanics based around textual lexia and link-following (but with a tradition of exploring alternative Strange Hypertext approaches) resulting in a dynamic of exploration and puzzle solving depending on whether agency is expressed at the level of Syuzhet or Fabula. Secondly, by looking at Games as Hypertexts; that depend heavily on textual content, use guard fields, patterns, and sculptural hypertext models to manage agency, that experiment with aporia and epiphany, and that take place within a wider interlinked transmedia experience. This analysis reveals that Narrative Games are both more and less than Hypertext, with a wider set of mechanics and interfaces, but possessed of a core hypertextuality and situated within a greater hypertext context. This suggests that there is much value to be gained from interactions between the communities invested in interactive narrative, and significant potential in the cross-pollination of ideas."

We demonstrate this effect using a utility-based framework for evaluating numerical web content popularity prediction tasks, focusing on highly popular items. Additionally, it is demonstrated that gains in predictive and ranking ability of such type of cases can be obtained via naïve approaches, based on strategies to tackle imbalanced domains learning tasks."

Most of the state-of-the-art methods in entity recommendation are limited in the sense that they allow users to search only in the immediate neighborhood of the entity of interest. This is majorly due to efficiency reasons as the search space increases exponentially as we move further away from the entity of interest in the graph. Often, users perform the search task in the context of an information need and we investigate the role this context can play in overcoming the scalability issue and improving knowledge graph exploration. Intuitively, only a small subset of entities in the graph are relevant to a users’ interest. We show how can we efficiently select this sub-set by utilizing contextual clues and using graph-theoretic measures to further re-rank this set to offer highly relevant graph exploration capabilities to end-users."

However, this prior work has been hampered by the assumption that the likelihood of users accepting friend requests from a bot is non-increasing—a useful constraint for theoretical purposes but one contradicted by observational data. We address this limitation with a novel curvature based technique, showing that an adaptive greedy bot is approximately optimal within a factor of 1 - 1/e1/δ ~0.165. This theoretical contribution is supported by simulating the infiltration of the bot on OSN topologies. Counter-intuitively, we observe that when the bot is incentivized to befriend friends-of-friends of target users it out-performs a bot that focuses on befriending targets."

Our approach complements existing content-based methods, and is based on a number of observations regarding article similarity and topicality. First, the popularity of a new article is correlated with the popularity of similar articles of recent publication. Second, the popularity of the new article is related to the recent historical popularity of its main topic.

In this work, we present an approach to efficiently extract structured summaries of news stories by augmenting news media with the structure of social discourse as reflected in social media in the form of social tags. Existing event detection, topic-modeling, clustering and summarization methods yield news story summaries based only on noun phrases and named entities. These representations are sensitive to the article wording and the keyword extraction algorithm. Moreover, keyword-based representations are rarely helpful for highlighting the inter-story connections or for reflecting the inner structure of the news story because of high word ambiguity and clutter from the large variety of keywords describing news stories. Our method combines the news and social media domains to create structured summaries of news stories in the form of hierarchies of keywords and social tags, named SocialTree. We show that the properties of social tags can be exploited to augment the construction of hierarchical summaries of news stories and to alleviate the weaknesses of existing keyword-based representations. In our quantitative and qualitative evaluation the proposed method strongly outperforms the state-of-the-art with regard to both coverage and informativeness of the summaries."

Over the last years, many popular RDF knowledge graphs have grown so large that rankings for the facts they contain cannot be computed directly using the currently common 64-bit platforms. In this paper, we tackle two problems: Computing ranks on such large knowledge bases efficiently and incrementally. First, we present D-HARE, a distributed approach for computing ranks on very large knowledge graphs. D-HARE assumes the random surfer model and relies on data partitioning to compute matrix multiplications and transpositions on disk for matrices of arbitrary size. Moreover, the data partitioning underlying D-HARE allows the execution of most of its steps in parallel. As very large knowledge graphs are often updated periodically, we tackle the incremental computation of ranks on large knowledge bases as a second problem. We address this problem by presenting I-HARE, an approximation technique for calculating the overall ranking scores of a knowledge without the need to recalculate the ranking from scratch at each new revision. We evaluate our approaches by calculating ranks on the 3 × 109 and 2.4 × 109 triples from Wikidata resp. LinkedGeoData. Our evaluation demonstrates that D-HARE is the first holistic approach for computing ranks on very large RDF knowledge graphs.

In this paper, we present the work done in order to prevent and detect account takeovers at mobile.de, an online vehicle marketplace. To tackle the prevention problem, we first present a behavioral analysis of how fraudsters operate, and implemented a mutual two-factor authentication that achieved a reduction of 43% of account takeovers. To tackle the detection problem, we introduce a concept drift sensitive machine learning training approach that was able to improve our baseline methods by 18% in detection rates. The automatic detection reduced the exposure of fraudulent listings by 69%, resulting in a safer marketplace for buyers and sellers."

These pages contain only “lorem ipsum” text, indistinct videos and images, non-functional links, and various font settings. Our findings show that perceived credibility is indeed affected by some purely presentational factors. Specifically, video presence increased credibility, while large fonts and having no images reduced credibility. Having a few, but not too many, images increased credibility for short articles, especially in the presence of large fonts. We also conducted follow-up interviews, which revealed that participants noticed images, videos, and font sizes when making credibility judgments, corroborating our quantitative experimental results."

In this paper, we investigate news media bias in the context of Brazilian presidential elections by comparing four popular news outlets during three consecutive election years (2010, 2014, and 2018). We analyse the textual content of news stories in search for three kinds of bias: coverage, association, and subjective language. Coverage bias has to do with differences in mention rates of candidates and parties. Association bias occurs when, for example, one candidate is associated with a negative concept while another not. Subjective bias, in turn, has to do with wording that attempts to influence the readers by appealing to emotion, stereotypes, or persuasive language. We perform a thorough analysis on a large scale news data set where several of such biases are exposed."

Electronic writing, like previous instances of writing, equally engages the double “mission” of writing: to varying degrees, writing is about a subject, but also about the medium through which it is transmitted. “Transmission,” then, suggests both the circulation of texts and the cross-purpose (“tram” = across or to cross + “mission” = purpose or intention) of inscription."

Multimodality—intended as the coexistence of multiple combinations of modes in the same application-can improve application richness and can accommodate the needs of different categories of users. On the other hand, multimodality increases complexity and may affect usability, since a variety of different interaction styles may be disorienting for the users. Designing an effective multimode hypermedia is a difficult problem. This paper discusses this issue, presenting a taxonomy of different kinds of modes in hypermedia applications and introducing the concept of modal hypermedia interaction. Modal interaction means that the semantics of normal application commands are dependent not only on the application state, as usual, but also on mode setting. We introduce a formal model for modal hypermedia interaction that helps us to analyse more precisely design alternatives and their impact on usability. We illustrate our approach by examples from a museum hypermedia called “Polyptych” that we actually built."

Based on the analysis of these issues, a team-and-role-based access control model is proposed, which describes various aspects of role-based access control in cooperative hypermedia environments. The model has been implemented in CHIPS, a cooperative hypermedia-based process support system. Application examples demonstrate that its organizational context management and access permission authorization retain the simplicity of RBAC. Our extensions provide effective and flexible access control for managing various kinds of shared workspaces, especially shared process spaces, where access control is not only used for managing security, but also for supporting coordination."

In this paper we discuss a model-based approach to the assessment of the development process of hypermedia applications. We propose a hypermedia development process reference model which guides the identification of suitable process quality attributes and subsequent assessment activities. We look at how this process assessment can be applied in improving development processes and hence hypermedia applications. We provide some examples that demonstrate the validity of the approach. The result is a technique which is capable of providing significant improvement in the development process and hence the quality of the applications which result from this process."

The problem is important because it facilitates determining social and market trends as well as efficient information paths among people. We describe communication flow by two parameters: the intent to communicate and communication delay. To estimate these parameters, we design features to characterize communication and social context. Communication context refers to the attributes of current communication. Social context refers to the patterns of participation in communication (information roles) and the degree of overlap of friends between two people (strength of ties). A subset of optimal features of the communication and social context is chosen at a given time instant using five different feature selection strategies. The features are thereafter used in a Support Vector Regression framework to predict the intent to communicate and the delay between a pair of individuals. We have excellent results on a real world dataset from the most popular social networking site, www.myspace.com. We observe interestingly that while context can reasonably predict intent, delay seems to be more dependent on the personal contextual changes and other latent factors characterizing communication, e.g. ‘age’ of information transmitted and presence of cliques among people."

We looked at the weekly polls released by the Associated Press (AP) and USA Today Coaches Poll. Both rank the top 25 teams according to the aggregated expertise of sports writers and college football coaches. For the entire 2008 season (8/2008 – 1/2009), we compared the ranking of teams (top 10 and top 25) according to the polls with the rankings of one to eight URLs associated with each team in Google, Live Search and Yahoo. We found moderate to high correlations between the final rankings of 2007 and the SE ranking in mid 2008 but the correlation between the polls and the SEs steadily decreased as the season went on. We believe this is because the rankings in the web graph (as reported via SEs) have “inertia” and do not rapidly fluctuate as do the teams’ on the field fortunes."

We also propose a vector space model Best of Breed which utilizes appropriate enrichment method based on the type of the query. We evaluate the proposed methods on a large dataset of 27 million resources, 92 thousand tags and 94 million tag assignments. Experimental results show that the enriched vector space models help in improving search, especially for the rare queries which have few relevant resources in the sparse data."

Even though all common web browsers were equipped with a history list and bookmarks early enough to facilitate this need, most users typically use search engines to refind information. However, both bookmarks and search based tools have significant limitations that impact their usability: the former are known to be hard to manage over the course of time, whereas the latter require the user to recall a specific combination of keywords or context. Most importantly, though, both are particularly inappropriate in cases where a piece of information is contained within an unstructured web page. In this paper, we present in-context annotation as a more efficient alternative to these methodologies. To verify this claim, we conducted a study in which we compare the performance of experienced users in all three approaches while revisiting specific pieces of information in the web after a long period of time. The outcomes suggest that in-context annotation clearly outperforms both traditional strategies."

Yet as the number of resources in Collaborative tagging system grows over time, sifting through the large amounts of resources and finding the right resources to recommend to the right user is becoming a challenging problem. In this paper, we investigate a probabilistic generative model for collaborative tagging, explore the implicit semantic connections in the sparse and noisy information space of heterogeneous users and unsupervised tagging. First, a modified Latent Dirichlet Allocation (LDA) model is used to cluster the tags and users simultaneously. The generalization of resource description and user could alleviate the tag noise and data sparseness of recommendation effectively. And then, considering that topic-based recommendation only takes the users’ global interest into consideration without the capability of distinguishing users’ interest in detail, we combine the global interests with the individual interest and community interest. Experimental results demonstrate the topic-based personalized recommendation method, which integrate both the commonality factor among users and the specialties of individuals, could alleviate data sparsity and provide a more flexible and effective recommendation than previous methods."

Chrysant provides general-purpose versioning capability to hypertext systems with an embedded link model. To apply Chrysant for a specific hypertext system, we require the containment model for this system’s data model, the containment model of the version repository for this system, the hypertext role definition, the versioning role definition, and the filesystem mapping definition. Additionally, a specific parser that retrieves the link targets from the hypertext resources is needed. Hypertext versioning is different from versioning an individual resource in the traditional way, in that both the content of a hypertext resource and the relationships between it and other resources related by hypertext links are versioned. In Chrysant, the structure container and the content of a hypertext resource are versioned separately. We describe the architecture of Chrysant, and explain the procedure of the check-in and check-out functions. An AF-BTU algorithm is introduced in the paper to check in the hypertext network of a hypertext resource. As a case study, the application of Chrysant for HTML content is introduced. We create necessary definition specifications for the HTML system and a parser to retrieve link targets from a HTML document. Some examples of HTML versioning with Chrysant are shown."

Our code generator, called Bamboo, is based on a Containment Modeling Framework (CMF) that uniformly describes data models for hypertext systems. CMF employs a lightweight modeling approach in which entities (system abstractions) and containment relationships are used to model hypertext system repositories. Given a description of a system repository data model using CMF, as well as a specification of the mapping between the domain specific roles (link, version history, etc.) and the entity definitions, Bamboo can generate an open hypertext repository that matches the specification. The benefits of this approach include a shorter development cycle, lower design and implementation costs, fewer design faults, a standard repository API, and extensibility for adding new features. We validate our approach by automatically generating repositories in accordance with the models of five existing hypertext systems. We also demonstrate the extensibility of our approach by quickly building a GUI client on top of a repository, and then subsequently adding version control capabilities by altering the containment model and regenerating the system."

Our method is shown to reduce the time spent searching the index, reduce the need to reformulate queries, and also increase the proportion of queries which fulfill the user’s information need. Our work provides a mere glimpse into a new field of study by introducing new types of linking between documents and users’ world views. Such links from world views have never previously been considered content that can be indexed and searched over."

One of the key features of the Web’s URIs is their ability to not only specify a resource, but to also identify a subresource within that resource, by using a fragment identifier. Fragment identification enables user to create better hypermedia. We present a proposal for fragment identifiers for plain text files, which makes it possible to identify character or line ranges, or subresources identified by regular expressions. Using these fragment identifiers, it is possible to create more specific hyperlinks, by not only linking to a complete plain text resource, but only the relevant part of it. Along with this proposal, a prototype implementation is described which can be used both as a server-side testbed and as a client-side extension for the Firefox browser."

Given a definition of similarities between pages, it is intuitive to estimate that any similarity will propagate from page to page, inducing an implicit topical relatedness between pages. In this paper, we extract connected subgraphs from the whole graph that consists of all pairs of pages whose similarity scores are above a given threshold, and then sort the candidates of related pages by a novel rank measure which is based on the combination distances of a flexible hierarchical clustering. Moreover, due to the subjectivity of similarity values, we dynamically supply the ordering list of related pages according to a parameter adjusted by users. We show our approach effectively handles a set of pages originating from three related categories of Web hierarchies, such as Google Directory. The experiments with three similarity measures demonstrate that using in-link information is favorable while using a combination measure of in-links and out-links lowers the precision of identifying similar pages."

Specifically, telephony voice applications offer immense usability and penetration benefits and can act as alternate information access and delivery mechanisms. Connectivity across voice applications poses interesting and novel challenges. In this paper, we define Hyperspeech as a voice fragment in a voice application that is a hyperlink to a voice fragment in another voice application. Further, we present Hyperspeech Transfer Protocol (HSTP) - a protocol to seamlessly connect telephony voice applications. HSTP enables the users to browse across voice applications by navigating the Hyperspeech content in a voice application. HSTP can also be used for developing cross-enterprise applications that allow a user to transact across two or more voice applications."

Huge amounts of data generated by social media users present opportunities and challenges to study these preferences in a large scale. In this paper, we aim to infer social media users’ political views when only network information is available. In particular, given personal preferences about some of the social media users, how can we infer the preferences of unobserved individuals in the same network? There are many existing solutions that address the problem of classification with networked data problem. However, networks in social media normally involve millions and even hundreds of millions of nodes, which make the scalability an important problem in inferring personal preferences in social media. To address the scalability issue, we use social influence theory to construct new features based on a combination of local and global structures of the network. Then we use these features to train classifiers and predict users’ preferences. Due to the size of real-world social networks, using the entire network information is inefficient and not practical in many cases. By extracting local social dimensions, we present an efficient and scalable solution. Further, by capturing the network’s global pattern, the proposed solution, balances the performance requirement between accuracy and efficiency."

Homophily, the theory which states that people who are similar tend to become friends, has been well studied in the setting of online social networks. When we focus on age attribute, based on this theory, online friends tend to have similar age. In this work, we take a step further and study the hypothesis that the age gap between online friends become even smaller in a larger friendship clique. We empirically validate our hypothesis using two real social network data sets. We further design a propagation-based algorithm to predict online users’ age, leveraging the clique-based hypothesis. We find that our algorithm can outperform several baselines. We believe that this method could work as a way to enrich sparse data and the hypothesis we validated would shed light on exploring the proximity of other user attributes such as education as well."

We have proposed a design of an interactive visualization, which provides the user of a social networking site with awareness of the personalization mechanism (the semantics and the source of the content that is filtered away), and with means to control the filtering mechanism. The visualization has been implemented in a peer-to-peer social network, called MADMICA, and we present here the results of a large scale lab study with 163 crowd-sourced participants. The results demonstrate that the visualization leads to increased users’ awareness of the filter bubble, understandability of the filtering mechanism and to a feeling of control over their data stream."

In this paper, we design two computational tasks by leveraging data mining and machine learning techniques to enable the computational understanding of distrust with social media data. The first task is to predict distrust from only trust, and the second task is to predict trust with distrust. We conduct experiments in real-world social media data. The empirical results of the first task provide concrete evidence to answer the question, “is distrust the negation of trust?” while the results of the second task help us figure out how valuable the use of distrust in trust prediction."

Three mechanisms are considered: endogenous stimuli, exogenous stimuli, and a mechanism that dictates the decay of interest of the population in a topic. We propose a model involving two parameters η* and λ describing the tweeting behaviour of users, which allow us to reconstruct the findings of Lehmann et al.

In this work we advance the study of this question by introducing Topic Consensus: a new measure that calculates the quality of a topic through investigating its consensus with some known topics underlying the data. We view the quality of the topics from three perspectives: 1) topic interpretability, 2) how documents relate to the underlying topics, and 3) how interpretable the topics are when the corpus has an underlying categorization. We provide insights into how well the results of Mechanical Turk match automated methods for calculating topic quality.

We found that although English is the most popular language used to tweet during conferences, a significant proportion of people also tweet in other languages. In addition, people who tweet solely in English interact mostly within the same group (English monolinguals), while people who speak other languages interact more with different lingua groups.

However, this approach disregards the question selection behaviour of the answers and how it is affected by factors such as question recency and reputation.

It is imperative to motivate young readers to read by offering them appealing books to read so that they can enjoy reading and gradually establish a reading habit during their formative years that can aid in promoting their good reading habits. However, with the huge volume of existing and newly-published books, it is a challenge for parents/educators (young readers, respectively) to find the right ones that match children’s interests and their read-ability levels. In response to the needs, we have developed K3Rec, a recommender which applies a multi-dimensional approach to suggest books that simultaneously match the interests/preferences and reading abilities of emergent (i.e., K-3) readers. K3Rec considers the grade levels, contents, illustrations, and topics, besides using special properties, such as length and writing style, to distinguish K-3 books from other books targeting more mature readers. K3Rec is novel, since it adopts an unsupervised strategy to suggest books for K-3 readers which does not rely on the existence of personal social media data, such as personal tags and ratings, that are seldom, if ever, created by emergent readers. Further-more, unlike existing book recommenders, K3Rec explicitly analyzes book illustrations, which is of special significance for emergent readers, since illustrations assist these readers in understanding the contents of books. K3Rec focuses on a niche group of readers that has not been explicitly targeted by existing book recommenders. Empirical studies conducted using data from BiblioNasium.com and Amazon’s Mechanical Turk have verified the effectiveness of K3Rec in making book recommendations for emergent readers."

It occurs in many situations such as a company collecting data on competition, a journalist surfing the Web to investigate a political scandal, or an archivist recording the activity of influential Twitter users during a presidential election. In all these applications, users explore a graph (e.g., the Web or a social network), nodes are discovered one by one, the total number of exploration steps is constrained, some nodes are more valuable than others, and the objective is to maximize the total value of the crawled subgraph. In this article, we introduce scalable, generic, and adaptive systems for focused crawling. Our first effort is to define an abstraction of focused crawling applicable to a large domain of real-world scenarios. We then propose a generic algorithm, which allows us to identify and optimize the relevant subsystems. We prove the intractability of finding an optimal exploration, even when all the information is available.####Taking this intractability into account, we investigate how the crawler can be steered in several experimental graphs. We show the good performance of a greedy strategy and the importance of being able to run at each step a new estimation of the crawling frontier. We then discuss this estimation through heuristics, self-trained regression, and multi-armed bandits. Finally, we investigate their scalability and efficiency in different real-world scenarios and by comparing with state-of-the-art systems."

Entity linking (EL) is the task of linking entities in a text to the corresponding entries in a knowledge base, such as Wikipedia. Recently, EL has received considerable attention. EL can be used to enhance a user’s text reading experience by streamlining the process of retrieving information on entities. Several EL methods have been proposed, though they tend to extract all of the entities in a document including unnecessary ones for users. Excessive linking of entities can be distracting and degrade the user experience. In this paper, we propose a new method for evaluating the helpfulness of linking entities to users. We address this task using supervised machine-learning with a broad set of features. Experimental results show that our method significantly outperforms baseline methods by approximately 5.7%-12% F1. In addition, we propose an application, Linkify, which enables developers to integrate EL easily into their web sites."

One problem to which researchers are confronted to when they study such cooperation is to build an intuitive representation of what is happening. Many tools and metrics exist to study the results of the cooperation, but sometimes, these metrics can be misleading if one doesn’t really observe what the cooperation process really looks like. The main proposition of this paper is a visualization of the cooperation flow. The novelty of our approach is to represent the internal structure of the cooperation in a longitudinal perspective. Through examples, we present how one can form a rich understanding of what form the cooperation takes in a given context, and how this understanding can help to formulate hypothesis which can consequently be studied with appropriate tools such as statistical analysis."

Due to the sheer volume of information generated during a disaster, a key challenge is to filter tweets from the crisis region so their analysis can be prioritized. In this paper, we introduce the task of identifying whether a tweet is generated from crisis regions and formulate it as a decision problem. This problem is challenging due to the fact that only ~1% of all tweets have location information. Existing approaches tackle this problem by predicting the location of the user using historical tweets from users or their social network. As collecting historical information is not practical during emergency situations, we investigate whether it is possible to determine that a tweet originates from the crisis region through the information in the tweet and the publishing user’s profile."

For example, a variation in the delivered Quality of Services (QoS) can frustrate buyers and they leave the e-marketplace, causing revenue loss. The inherent uncertainties of open marketplaces motivate the design of reputation systems to facilitate buyers in finding honest feedback from other buyers (advisers). Defining the threshold for acceptable level of honesty of advisers is very important, since inappropriately set thresholds would filter away possibly good advice, or the opposite - allow malicious buyers to badmouth good services. However, currently, there is no systematic approach for setting the honesty threshold. We propose a self-adaptive honesty threshold management mechanism based on PID feedback controller. Experimental results show that adaptively tuning the honesty threshold to the market performance enables honest buyers to obtain higher quality of services in comparison with static threshold values defined by intuition and used in previous work."

In this article we present our research in the identification and characterization of user sentiment profiles in online social media. By analyzing a dataset of more than 36,000 users, we identify several distinctive groups, according to similarities in their sentiment behavior. We study differences and similarities between these profile clusters and present detailed statistics. We found that a large number of Twitter users can be grouped in nine distinct profiles according to the strength and polarity of their sentiment.

Some evidence indicates that for educational purposes, the disadvantages of personalized search are not justified by its benefits. The potential issues with search personalization, especially in an educational context, include loss of serendipity and capability, commercialization of education and the “Filter Bubble” effect where users are denied information if search engine algorithms decide it is irrelevant to them. The majority of students in higher education make use of general-purpose search engines to find academic information, however we have little knowledge about the effects of personalization on learners’ experience and achievements. This observation motivates the research in this paper. First, we surveyed 120 university students to investigate which research sources, including search engines they predominately use and how much they depend on each for educational purposes. We learned that the majority of students prefer Google to other search engines; indeed sometimes it is their primary or only information-seeking tool. Additionally, about 80% of them use search engines for educational purposes on daily basis. Second, we measured the difference between personalized and non-personalized search results for 120 academic search queries divided equally into four categories: Education, IT, Health sciences and Business. Our results showed that on average only 53% of links appear, not necessarily in the same order, in both personalized and non-personalized search results. Interestingly, we observed only slight differences in the extent of personalization based on academic topics."

Unfortunately, the methods in which Twitter selects data to disseminate through the stream are either vague or unpublished. Since Twitter maintains sole control of the sampling process, it leaves us with no knowledge of how the data that we collect for research is selected. Additionally, past research has shown that there are sources of bias present in Twitters dissemination process. Such bias introduces noise into the data that can reduce the accuracy of learning models and lead to bad inferences. In this work, we take an initial look at the efficiency of Twitter limit track as a sample population estimator. After that, we provide methods to mitigate bias by improving sample population coverage using clustering techniques."

Meanwhile, automatic lexicon building methods are overly dependent on seed words but neglect the effect of emoticons which are natural graphical labels of fine-grained emotion. In this paper, we propose a novel emotion lexicon building framework that leverages both seed words and emoticons simultaneously to capture emotion distributions of candidate words more accurately. Our method overcomes the weakness of existing methods by combining the effects of both seed words and emoticons in a unified three-layer heterogeneous graph, in which a multi-label random walk (MLRW) algorithm is performed to strengthen the emotion distribution estimation. Experimental results on real-world data reveal that our constructed emotion lexicon achieves promising results for emotion classification compared to the state-of-the-art lexicons."

Therefore, the usability and the overall design quality of an application can determine its success or failure. In this paper, we analyze the conceptual model of CMS-based web applications in terms of the incorporated design fragments that support the various user interaction processes. We consider these fragments as recurrent interaction patterns occurring in the application model, consisting of a configuration of front-end interface components that interrelate each other and interact with the user to achieve certain functionality. We have developed a methodology that automatically extracts the conceptual model of a web application and subsequently performs a pattern-based analysis of the model in order to identify the occurrences of all the recurrent interaction patterns. Finally, we calculate evaluation metrics revealing whether these patterns are used consistently throughout the application design. By utilizing these patterns, developers can produce more consistent and predictable designs, improving the ease of use of web applications."

We also constructed a classifier that separates reviews of documentaries from reviews of feature films with an accuracy of 71.32%. However, as our goal with this paper is not to improve the accuracy of predicting the rating and type or genre of film reviews, but to advance our understanding of the perception of documentaries in comparison to feature films, we also identified commonalities and differences between these two types of films as well as between low versus high ratings. We find that in contrast to reviews of feature films, comments on documentaries are shorter but composed of longer sentences, are less emotional, contain less positive and more negative terms, are lexically more concise, and are more focused on verbs than on nouns and adjectives. Compared to low-rated reviews, comments with a high rating are shorter, are more emotional and contain more positive than negative sentiment, and have less question marks and more exclamation points. Overall, this work contributes to advancing our understanding of the impact of different types of information products on individual information consumers."

Many contagion dynamics models that have been used to model Twitter, Facebook, and blog information transmission are polynomial-time computable, and hence can be efficiently simulated on networked populations. Game-theoretic models of collective action (i.e., coordination problems that require common knowledge among agents), however, have dynamics that are controlled in part by specific network structures such as cliques and bicliques. Contagion dynamics with these models cannot be efficiently computed because finding all bicliques in a graph, for example, is an NP-hard problem. We investigate a recent model of common knowledge dynamics that represents information spread on Facebook in which the biclique is the characterizing structure and convert the model into an efficiently computable one by using an approximation. We demonstrate this through experiments on seven different graphs for a total of 168 sets of conditions, including a 4-order of magnitude span in dynamics parameter values. Our approach speeds computations in two ways: (i) it obviates the need to find all bicliques in a social network, which is a very time-onsuming task (computations can take 30 to 120 hours or more of wall clock time), and (ii) it reduces the time of simulation computations, in some cases by well over an order of magnitude.

OpenStreetMap is one of the most successful examples of such paradigm, where the goal of building a global map of the world is collectively performed by over 2M contributors. Despite geographic information being intrinsically evolving, little research has so far gone into analysing maintenance practices in these domains. In this paper, we perform a preliminary exploration to quantitatively capture maintenance dynamics in geographic crowd-sourced datasets, in terms of: the extent to which different maintenance actions are taking place, the type of spatial information that is being maintained, and who engages in these practices. We apply this method to 117 countries in OSM, over one year of mapping activity. Our findings reveal that, although maintenance practices vary substantially from country to country in terms of how widespread they are, strong commonalities exist in terms of what metadata is being maintained and by whom."

For example, an account posting general news information is a non-targeting account, while an account posting announcements to members of a specific organization is a targeting account. An account posting information on very specific minor topic, and an account used for communication with friends, are also targeting accounts. Our method finds some properties that are common to most followers of a given account, and calculate how much a user set with such a consistency deviates from a random sample from the given universe of users (e.g., the set of all Twitter users in some country). If it largely deviates, the account is a targeting account. We use two types of properties of followers: (1) terms in their metadata and (2) their followees. The result of our experiment shows that one of our methods, which computes two scores based on these two types of properties and combines them using SVM, achieves the accuracy 0.944, and outperforms the baselines."

However, there is little work analyzing the characteristics of abusive users and what distinguishes them from typical social media users. In this paper, we start addressing this gap by analyzing tweets containing a great amount of abusiveness. We focus on a Twitter dataset revolving around the Gamergate controversy, which led to many incidents of cyberbullying and cyberaggression on various gaming and social media platforms. We study the properties of the users tweeting about Gamergate, the content they post, and the differences in their behavior compared to typical Twitter users.####We find that while their tweets are often seemingly about aggressive and hateful subjects, “Gamergaters” do not exhibit common expressions of online anger, and in fact primarily differ from typical users in that their tweets are less joyful. They are also more engaged than typical Twitter users, which is an indication as to how and why this controversy is still ongoing. Surprisingly, we find that Gamergaters are less likely to be suspended by Twitter, thus we analyze their properties to identify differences from typical users and what may have led to their suspension. We perform an unsupervised machine learning analysis to detect clusters of users who, though currently active, could be considered for suspension since they exhibit similar behaviors with suspended users. Finally, we confirm the usefulness of our analyzed features by emulating the Twitter suspension mechanism with a supervised learning method, achieving very good precision and recall."

In this paper, we investigate the potential of social media in characterizing and understanding abstinence from tobacco or alcohol use. While the link between behavior and addiction has been explored in psychology literature, the lack of longitudinal self-reported data on long-term abstinence has challenged addiction research. We leverage the activity spanning almost eight years on two prominent communities on Reddit: StopSmoking and StopDrinking. We use the self-reported “badge” information of nearly a thousand users as gold standard information on their abstinence status to characterize long-term abstinence. We build supervised learning based statistical models that use the linguistic features of the content shared by the users as well as the network structure of their social interactions. Our findings indicate that long-term abstinence from smoking or drinking (~one year) can be distinguished from short-term abstinence (~40 days) with 85% accuracy. We further show that language and interaction on social media offer powerful cues towards characterizing these addiction-related health outcomes. We discuss the implications of our findings in social media and health research, and in the role of social media as a platform for positive behavior change and therapy."

However, information retrieval and recommendation tasks have largely ignored emotion as a source of user context, in part because emotion is difficult to measure and easy to misunderstand. In this paper we explore the role of emotions in short films and propose an approach that automatically extracts affective context from user comments associated to short films available in YouTube, as an alternative to explicit human annotations. We go beyond the traditional polarity detection (i.e., positive/negative), and extract for each film four opposing pairs of primary emotions: joy-sadness, anger-fear, trust-disgust, and anticipation-surprise. Finally, in our empirical evaluation, we show how the affective context extracted automatically can be leveraged for emotion-aware film recommendation."

Modelling arguments on the social web is a challenge for those studying computational argumentation as formal models of argumentation tend to assume a logical argument, whereas argumentation on the social web is often largely rhetorical. To investigate the application of logical versus rhetorical techniques on the social web, we bring together two ontologies used for modelling argumentation and online communities respectively, the Argument Interchange Format and the Semantic Interlinked Online Communities project. We augment these with our own ontology for modelling rhetorical argument, the Argumentation on the Social Web Ontology, and trial our additions by examining three case studies following argumentation on different categories of social media. Finally, we present examples of how rhetorical argumentation is used in the context of the social web and show that there are clear markers present that can allow for a rudimentary estimate for the classification of a social media post with regards to its contribution to a discussion."

Moreover, the use of these networks has introduced a completely new way of collaboration among people, virtually creating spheres of friends who generally feel comfortable discussing a variety of subjects and even helping each other to grow in knowledge about certain subjects. In this work, we built and analyzed networks of social groups on Twitter related to the top leading causes of death in the United States. Due to space limitations, we present results for the state of Florida and only for the top four leading causes of death. We show that using a concept of time window in the creation of relations between users, we can reconstruct social networks for these conversations and these networks have characteristics that are similar to typical social networks. The argument is that social network information can be extracted even in cases where users are not directly talking to each other (as it is the case in most of Twitter)."

In our previous work, we developed an algorithm called Scanpath Trend Analysis (STA) that analyses eye movement sequences (i.e., scanpaths) of multiple users on a web page and identifies their most commonly followed path in terms of the visual elements of the page. These visual elements are mainly the segments of a page generated by automated segmentation approaches. In our previous work, we also showed that the STA algorithm performs better than other existing algorithms in terms of providing the most representative scanpath of users. However, we did not know whether the validity of the algorithm is limited to a particular segmentation approach. In this paper, we investigate the effect of two different segmentation approaches on the STA algorithm. The results suggest that the validity of the algorithm is not affected by the segmentation approach used. Specifically, the resulting scanpath of the STA algorithm is the most representative scanpath of users in comparison with the resulting scanpaths of other existing algorithms regardless of the segmentation approach used."

We proposed two hypotheses—teens as digital natives and the need for social interactions—as the theoretical framework for understanding the factors that help explain the behavioral differences. Our computational analysis identified the following novel findings: (1) teens post fewer photos than adults; (2) teens remove more photos based on the number of Likes the photos received; and (3) teens have less diverse photo content. Our analysis was also able to confirm prior ethnographic accounts that teens are more engaged in Liking and commenting, and express their emotions and social interests more than adults.

Specifically, we study the similarity of a user’s friendship and the evenness of friendship distribution in multiple OSNs. Our study shows that most users in Twitter and Instagram prefer to maintain different friendships in the two OSNs, keeping only a small clique of common friends in across the OSNs. Based upon our empirical study, we conduct link prediction experiments to predict missing friendship links in multiple OSNs using the neighborhood features, neighborhood friendship maintenance features and cross-link features. Our link prediction experiments shows that unsupervised methods can yield good accuracy in predicting links in one OSN using another OSN data and the link prediction accuracy can be further improved using supervised method with friendship maintenance and others measures as features."

Using a dataset of 20,877 food businesses in Singapore, we conduct analysis of several key factors including business categories, locations, and neighboring businesses. From these factors, we extract a set of relevant features and develop a robust predictive model to estimate the popularity of a business location. Our experiments have shown that the popularity of neighboring business contributes the key features to perform accurate prediction.

Moreover, at the time of the earthquake, telephone and e-mail services could not be used in many cases-although social networking services (SNSs) were still available. In an emergency, such as an earthquake, users proactively convey information on telecommunications network conditions through SNSs. Therefore the collective intelligence of SNSs is suitable as a means of information detection complementary to conventional observation through network monitoring devices. In this paper, we propose a network failure detection system that detects telephony failures with a high degree of accuracy by using the collective intelligence of Twitter, one of the most widely used SNSs. We also show that network control can be performed automatically and autonomically using information on telecommunications network conditions detected with our system."

In social media, people express their beliefs and attitudes not only on issues but also about each other through both their conversations and platform-specifc interactions such as like, share in Facebook and retweet in Twitter. While there are explicit “like” features in these platforms, there is no explicit “dislike” feature. Many network analysis tasks, such as detecting communities and monitoring their dynamics (i.e. polarization patterns) require information about both positive and negative linkages. Hence, predicting negative links between users is an important task and a challenging problem. In this study, we propose an unsupervised framework to predict the negative links between users by utilizing explicit positive interactions and sentiment cues in conversations. We show the effectiveness of the proposed framework on a political Twitter dataset annotated through Amazon MTurk crowdsourcing platform. Our experimental results show that the proposed framework outperforms other well-known methods and proposed baselines. To illustrate the contribution of the predicted negative links, we compare the community detection accuracies using signed and unsigned user networks. Experimental results using predicted negative links show superiority on three political datasets where the camps are known a priori. We also present qualitative evaluations related to the polarization patterns (i.e. rivalries and coalitions) between the detected communities which is only possible in the presence of negative links."

In comparison to an alternative generative model (Latent Dirichlet Allocation (LDA), we find that the proposed community-based model improves the empirical likelihood of held-out test data and discovers more coherent interest-based communities. Based on the community-based probabilistic tagging model, we develop a novel community-based ranking model for effective community-based exploration of socially-tagged Web resources.

Key challenge in supporting personalization is the need for rich metadata such as cognitive metadata about documents. As we consider size of large knowledge bases, manual annotation is not scalable and feasible. On the other hand, automatic mining of cognitive metadata is challenging since it is very difficult to understand underlying intellectual knowledge about documents automatically. To alleviate this problem, we introduce a novel metadata extraction framework, which is based on fuzzy information granulation and fuzzy inference system for automatic cognitive metadata mining. The user evaluation study shows that our approach provides reasonable precision rates for difficulty, interactivity type, and interactivity level on the examined 100 documents. In addition, proposed fuzzy inference system achieves improved results compared to a rule-based reasoner for document difficulty metadata extraction (11% improvement)."

We assume that a Wikipedia link between historical entities represents an impact propagation. That is, when an entity has a link to another entity, we regard the former is influenced by the latter. Historical entities in Wikipedia usually have the date and location of their occurrence. Our proposed iteration algorithm propagates such initial tempo-spacial information through links in the similar manner as PageRank, so the tempo-spacial impact scores of all the historical entities can be calculated. We assume that a historical entity is significant if it influences many other entities that are far from it temporally or geographically.

This public conversations can be studied from a Social Network Analysis perspective in order to highlight the structure of the “talk” network. In this paper we focus on this preliminary extraction step by proposing different algorithms. We then empirically validate the differences in the networks they generate on the Venetian Wikipedia with the real network of conversations extracted manually by coding every message left on all user talk pages. The comparisons show that both the algorithms and the manual process contain inaccuracies that are intrinsic in the freedom and unpredictability of Wikipedia syntax and practices. Nevertheless, a precise description of the involved issues allows to make informed decisions and to base empirical findings on reproducible evidence. Our goal is to lay the foundation for a solid computational sociology of wikis. For this reason we release the scripts encoding our algorithms as open source and also some datasets extracted out of Wikipedia conversations, in order to let other researchers replicate and improve our initial effort."

The task is to extract opinions expressed on entities and their attributes. For example, the sentence, “I love the picture quality of Sony cameras,” expresses a positive opinion on the picture quality attribute of Sony cameras. Sony is the entity. This paper focuses on mining entities (e.g., Sony). This is an important problem because without knowing the entity, the extracted opinion is of little use. The problem is similar to the classic named entity recognition problem. However, there is a major difference. In a typical opinion mining application, the user wants to find opinions on some competing entities, e.g., competing or relevant products. However, he/she often can only provide a few names as there are too many of them. The system has to find the rest from a corpus. This implies that the discovered entities must be of the same type/class. This is the set expansion problem. Classic methods for solving the problem are based on distributional similarity. However, we found this method is inaccurate. We then employ a learning-based method called Bayesian Sets. However, directly applying Bayesian Sets produces poor results. We then propose a more sophisticated way to use Bayesian Sets. This method, however, causes two major problems: entity ranking and feature sparseness. For entity ranking, we propose a re-ranking method to solve the problem. For feature sparseness, we propose two methods to re-weight features and to determine the quality of features. These methods help improve the mining results substantially. Additionally, like any learning algorithm, Bayesian Sets requires the user to engineer a set of features. We design some generic features based on part-of-speech tags of words for learning, which thus does not need to engineer features for each specific domain. Experimental results using 10 real-life datasets from diverse domains demonstrated the effectiveness of the proposed technique."

Unfortunately, the idea was dismissed in favor of a more technical-looking presentation, and thus was never demonstrated publicly. This paper re-considers Pale Fire’s position in hypertext history, and posits that if it was used in this early hypertext demonstration, it would have been the ‘father of all hypertext demonstrations’ to complement Douglas Engelbart’s ‘Mother of All Demos’ in 1968. In order to demonstrate the significance of Pale Fire’s hypertextuality and Nelson’s ambitions to use it, this paper will explore its hypertextual structure, the implication thereof for the novel and evaluate its success as a hypertext compared to electronic systems."

Small World (USW) graphs using different attacker strategies and report their respective robustness. Using different attacker profiles, we construct a game where the attacker is allowed to use a strategy of his choice to remove a percentage of each graph’s elements. The graph is then allowed to repair some portion of its self. We report on the number of alternating attack and repair turns until either the graph is disconnected, or the game exceeds the number of permitted turns. Based on our analysis, an attack strategy that focuses on removing the vertices with the highest betweenness value is most advantageous to the attacker. Power law graphs can become disconnected with the removal of a single edge; random graphs with the removal of as few as 1% of their vertices, small-world graphs with the removal of 14% vertices, and USW with the removal of 17% vertices. Watts-Strogatz small-world graphs are more robust and resilient than random or power law graphs. USW graphs are more robust and resilient than small world graphs. A graph of USW connected WOs filled with date could outlive the individuals and institutions that created the data in an environment where WOs are lost due to random failures or directed attacks."

It has piqued a lot of interest in the hypertext community in recent years because of its aim of revolutionizing electronic access to information and knowledge bases. In ZigZag information is stored in cells that are arranged into lists organized along unlimited numbers of intersecting sets of associations called dimensions. To this infrastructure a mechanism of transclusion is added, allowing the data stored in cells to span, and hence be utilized, in different contexts. Proponents of ZigZag claim that it is a flexible and universal structure for information representation, and yet the system has not been widely adopted and has been implemented even more rarely. In this paper we address the question of whether there are intrinsic theoretical reasons as to why this is the case.####While the basic features and specifications of ZigZag are well known, we delve in to the less understood area of its theoretical underpinnings to tackle this question. By modeling ZigZag within the framework of set theory we reveal a new class of hyperstructure that contains no referencable link objects whatsoever, instead grouping non-referencable binary associations into disjunct but parallel sets of common semantics (dimensions). We go on to further specialize these “dimensional models” into sets of finite partial functions, which are closed over a single domain, isolating the new class of hyperstructures we are calling hyperorders. This analysis not only sheds light on the benefits and limitations of the ZigZag hypermedia system, but also provides a framework to describe and understand a wider family of possible hyperstructure models of which it is an early example. Characteristics of Zigzag’s transclusion mechanisms are also investigated, highlighting a previously unrecognized distinction, and potential irrevocable conflict, between two distinct uses of content reuse: instance and identity transclusion."

Using empirical data, we characterize several properties of Web traffic that cannot be reproduced with Markovian models but can be explained by an agent-based model that adds several realistic browsing behaviors. First, agents maintain bookmark lists used as teleportation targets. Second, agents can retreat along visited links, a branching mechanism that can reproduce behavior such the back button and tabbed browsing. Finally, agents are sustained by visiting pages of topical interest, with adjacent pages being related. This modulates the production of new sessions, recreating heterogeneous session lengths. The resulting model reproduces individual behaviors from empirical data, reconciling the narrowly focused browsing patterns of individual users with the extreme heterogeneity of aggregate traffic measurements, and leading the way to more sophisticated, realistic, and effective ranking and crawling algorithms."

We argue that emphasis on one type of link when ranking documents can benefit the retrieval for that type of query. We start by presenting a link intent classification approach based on the link context representations that captures evidence from anchors, target pages, and their associated links, and then introduce our enhanced retrieval model that incorporates link intent into the estimation of anchor text importance. Comparative experiments on two large scale web corpora demonstrate the efficacy of our approaches."

In this work, we introduce a new similarity measure for ontological concepts that takes these issues into account.

The evaluation of our approach shows an improvement over Leacock and Chodorow’s distance based measure. Finally, we provide two application domains which can benefit when this similarity measure is used."

We investigate this problem in the context of the collaborative editing of articles in Wikipedia, showing that there is enough information in the edit history of the articles that can be utilized for predicting the attitude of co-editors. We train a model using a distant supervision approach, by labeling interactions between editors as positive or negative depending on how these editors vote for each other in Wikipedia admin elections. We use the model to predict the attitude among other editors, who have neither run nor voted in an election. We validate our model by assessing its accuracy in the tasks of predicting the results of the actual elections, and identifying controversial articles. Our analysis reveals that the interactions in co-editing articles can accurately predict votes, although there are differences between positive and negative votes. For instance, the accuracy when predicting negative votes substantially increases by considering longer traces of the edit history. As for predicting controversial articles, we show that exploiting positive and negative interactions during the production of an article provides substantial improvements on previous attempts at detecting controversial articles in Wikipedia."

However, this approach will not suffice for documents with very few inlinks, and it does not incorporate the document’s full context. To mediate these problems, we employ link paths, which contain anchor texts from paths through the Web ending at the document in question. We propose and study several different ways to aggregate anchor text from link paths, and we show that the information from link paths can be used to (1) improve known item search in site-specific search, and (2) map Web pages to database records.

One of them is the information leakage, i.e., information could be spread via OSNs to the users whom we are not willing to share with. Thus the problem of constructing a circle of trust to share information with as many friends as possible without further spreading it to unwanted targets has become a challenging research topic but still remained open.####Our work is the first attempt to study the Maximum Circle of Trust problem seeking to share the information with the maximum expected number of poster’s friends such that the information spread to the unwanted targets is brought to its knees. First, we consider a special and more practical case with the two-hop information propagation and a single unwanted target. In this case, we show that this problem is NP-hard, which denies the existence of an exact polynomial-time algorithm. We thus propose a Fully Polynomial-Time Approximation Scheme (FPTAS), which can not only adjust any allowable performance error bound but also run in polynomial time with both the input size and allowed error. FPTAS is the best approximation solution one can ever wish for an NP-hard problem. We next consider the number of unwanted targets is bounded and prove that there does not exist an FPTAS in this case. Instead, we design a Polynomial-Time Approximation Scheme (PTAS) in which the allowable error can also be controlled. Finally, we consider a general case with many hops information propagation and further show its #P-hardness and propose an effective Iterative Circle of Trust Detection (ICTD) algorithm based on a novel greedy function. An extensive experiment on various real-word OSNs has validated the effectiveness of our proposed approximation and ICTD algorithms."

Since users are often influenced by their friends, “word-of-mouth” exchanges so-called viral marketing in social networks can be used to increases product adoption or widely spread content over the network. The common perception of viral marketing about being cheap, easy, and massively effective makes it an ideal replacement of traditional advertising. However, recent studies have revealed that the propagation often fades quickly within only few hops from the sources, counteracting the assumption on the self-perpetuating of influence considered in literature. With only limited influence propagation, is massively reaching customers via viral marketing still affordable? How to economically spend more resources to increase the spreading speed?####We investigate the cost-effective massive viral marketing problem, taking into the consideration the limited influence propagation. Both analytical analysis based on power-law network theory and numerical analysis demonstrate that the viral marketing might involve costly seeding. To minimize the seeding cost, we provide mathematical programming to find optimal seeding for medium-size networks and propose VirAds, an efficient algorithm, to tackle the problem on large-scale networks. VirAds guarantees a relative error bound of O(1) from the optimal solutions in power-law networks and outperforms the greedy heuristics which realizes on the degree centrality. Moreover, we also show that, in general, approximating the optimal seeding within a ratio better than O(log n) is unlikely possible."

We then describe a method for early detection of these buzzwords, which is dependent on identifying the blogger communities which are closely related to these buzzwords. Moreover, we verify the effectiveness of the proposed method through experimentation that compares the rankings of several buzzword candidates with a real-life idol group popularity competition."

In this paper, we engineer and evaluate solutions that analyze the semantics of Social Web data streams to solve these challenges. We introduce Twitcident, a framework and Web-based system for filtering, searching and analyzing information about real-world incidents or crises. Given an incident, our framework automatically starts tracking and filtering information that is relevant for the incident from Social Web streams and Twitter particularly. It enriches the semantics of streamed messages to profile incidents and to continuously improve and adapt the information filtering to the current temporal context. Faceted search and analytical tools allow people and emergency services to retrieve particular information fragments and overview and analyze the current situation as reported on the Social Web.####We put our Twitcident system into practice by connecting it to emergency broadcasting services in the Netherlands to allow for the retrieval of relevant information from Twitter streams for any incident that is reported by those services. We conduct large-scale experiments in which we evaluate (i) strategies for filtering relevant information for a given incident and (ii) search strategies for finding particular information pieces. Our results prove that the semantic enrichment offered by our framework leads to major and significant improvements of both the filtering and the search performance.

We find that 70% of users in the sample tweet across multiple information streams, frequently engaging in what could be described as serial activism. We furthermore determined the dominant language in each hashtag to trace which users overlap between the thematic and linguistic communities delineated by different information streams. Although social media is frequently assumed to bring together people of different nationalities and cultures to discuss a wide range of controversial issues, our results indicate that the underlying social network that connects hashtags through overlapping users is heavily limited to linguistic and content-oriented communities. Information streams are clustered around linguistic communities, and hashtags within the same language group are clustered around well-defined topics, such as health, entertainment and politics. The only information streams that transcend language barriers are activism-related hashtags, which cluster information streams in different languages. Contrasting with the assumption that social media acts as the enabler of a globalized public debate, our results indicate a linear relationship between users who are very active in political hashtags and users who tweet across multiple political hashtags. The results suggest that activist campaigns based on social media are driven by a relatively small number of highly-active, politically engaged users."

This work focuses on ‘prescriptive tags’ that have associated some implicit behaviour in the user’s mind. So far, little support is given for the automation of this “implicit behaviour”, more to the point, if this behaviour is outside the tagging site. This paper introduces the notion of ‘reactive tags’ as a means for tagging to impact sites other than the tagging site itself. The operational semantics of reactive tags is defined through event-condition-action rules. Events are the action of tagging. Conditions check for additional data. Finally, rule’s actions might impact someone else’s account in a different website. The specification of this behaviour semantics is hidden through a graphical interface that permits users with no programming background to easily associate ‘reactions’ to the act of tagging. A working system, TABASCO, is presented as proof of concept."

To automate and enhance the process of locating high-quality answers to a user’s question Q at a CQA website, we introduce a CQA refinement system, called QAR. Given Q, QAR first retrieves a set of CQA questions QS that are the same as, or similar to, Q in terms of its specified information need. Thereafter, QAR selects as answers to Q the top-ranked answers (among the ones to the questions in QS) based on various similarity scores and the length of the answers. Empirical studies, which were conducted using questions provided by the Text Retrieval Conference (TREC) and Text Analysis Conference (TAC), in addition to more than four millions questions (and their corresponding answers) extracted from Yahoo! Answers, show that QAR is effective in locating archived answers, if they exist, that satisfy the information need specified in Q. We have further assessed the performance of QAR by comparing its question-matching and answer-ranking strategies with their Yahoo! Answers’ counterparts and verified that QAR outperforms Yahoo! Answers in (i) locating the set of questions QS that have the highest degrees of similarity with Q and (ii) ranking archived answers to QS as answers to Q."

There has not, however, been any detailed study of what readers think they are doing as they reread hypertext fiction that changes dynamically as the result of reader choice. An understanding of this would help authors/designers of hypertext fiction create better hypertext that is explicitly intended to encourage rereading.####To explore this issue, we conducted semi-structured interviews with participants who repeatedly read a complex hypertext fiction. Participants had trouble describing what they were doing as “rereading”, and were looking for either the text, or their understanding of the story, to remain constant between readings. This difficulty highlights the paradoxical nature of rereading in interactive stories, and suggests the need for further research into this phenomenon."

The automatic inference of user background information can be used to complete user profiles which in turn supports various recommendation mechanisms. This work illustrates the application of supervised learning mechanisms to analyze a large online corpus of tagged academic literature for extraction of user characteristics from tagging behavior. As a representative example of background characteristics we mine the user’s research discipline. Our results show that tags convey rich information that can help designers of those systems to better understand and support their prolific users - users that tag actively - beyond their interests."

Detecting communities of similar nodes from such networks is a challenging problem. Most existing algorithms for community detection in folksonomies assign unique communities to nodes, whereas in reality, users have multiple topical interests and the same resource is often tagged with semantically different tags. The few attempts to detect overlapping communities work on projections of the hypergraph, which results in significant loss of information contained in the original tripartite structure. We propose the first algorithm to detect overlapping communities in folksonomies using the complete hypergraph structure. Our algorithm converts a hypergraph into its corresponding line-graph, using measures of hyperedge similarity, whereby any community detection algorithm on unipartite graphs can be used to produce overlapping communities in the folksonomy. Through extensive experiments on synthetic as well as real folksonomy data, we demonstrate that the proposed algorithm can detect better community structures as compared to existing state-of-the-art algorithms for folksonomies."

In doing so, we study different established notions of network diversity, based on paths in the network, degree distributions, eigenvalues, cycle distributions, and control models. This leads to five appropriate characteristic network statistics that capture corresponding aspects of network diversity: effective diameter, Gini coefficient, fractional network rank, weighted spectral distribution, and number of driver nodes of a network. Consequently, we present and discuss comprehensive experiments with a broad range of directed, undirected, and bipartite networks from several different network categories—including hyperlink, interaction, and social networks. An important general observation is that network diversity shrinks over time. From the conceptual perspective, our work generalizes previous work on shrinking network diameters, putting it in the context of network diversity. We explain our observations by means of established network models and introduce the novel notion of eigenvalue centrality preferential attachment."

Social scientists have developed influential theories about the role of network structure in information access. These theories were validated through numerous studies, which examined how individuals leverage their social networks for competitive advantage, such as a new job or higher compensation. It is not clear how these theories generalize to online networks, which differ from real-world social networks in important respects, including asymmetry of social links. We address this problem by analyzing how users of the social news aggregator Digg adopt stories recommended by friends, i.e., users they follow. We measure the impact different factors, such as network position and activity rate; have on access to novel information, which in Digg’s case means set of distinct news stories. We show that a user can improve his information access by linking to active users, though this becomes less effective as the number of friends, or their activity, grows due to structural network constraints. These constraints arise because users in structurally diverse position within the follower graph have topically diverse interests from their friends. Moreover, though in most cases user’s friends are exposed to almost all the information available in the network, after they make their recommendations, the user sees only a small fraction of the available information. Our study suggests that cognitive and structural bottlenecks limit access to novel information in online social networks."

Social media has been widely adopted by younger adults, but older adults have been less likely to use such applications. A survey of 142 older adults (Mage=72 years, SD=11; range: 52-92) living in the metropolitan Atlanta area was conducted to understand the characteristics of older adults who do and do not use Facebook, a popular and wide-spread social media application. The present study examined the relationship between Facebook use and loneliness, social satisfaction, and confidence with technology. Demographic relationships were also examined, such as gender and age. Fifty-nine participants (42%) identified themselves as current Facebook users; 83 participants (58%) were not Facebook users. Non-Facebook users were significantly older (Mage= 75.3 years) than Facebook users (Mage= 66.5 years). Counter to expectations, there was not a significant difference in loneliness between Facebook users and non-users for this sample. However, Facebook users did score higher on assessments of social satisfaction and confidence with technology than did non-users. These preliminary results suggest that many older adults do use Facebook and they primarily use it to stay connected with family. As adults enter into older adulthood, maintaining social connectedness may become more difficult due to mobility limitations, chronic diseases, and other age-related issues, thus decreasing physical connectedness with friends, family, and community. For these reasons, social media may begin to play a more active role in keeping this population socially connected. Therefore, understanding the factors that influence social media use in older adults is becoming more critical."

Such a tool could be of value for helping social scientists to navigate the overwhelming amounts of data that are produced on Twitter. To evaluate our tool, we select three concepts of interest to social scientists (i.e., privacy, serendipity, and Occupy Wall Street), build ground truths for each concept using the Grounded Theory approach, and perform a quantitative assessment based on two widely-used information retrieval metrics. To then offer qualitative assessments complementary to the quantitative ones, we run a user study involving 32 individuals. We find that simple information-theoretic association measures are more accurate than frequency-based measures. We also spell out under which conditions these metrics tend to work best."

For centuries, printed pamphlets or booklets have been the common way to provide the audiences with this information. Unfortunately, printed programs are not always the most efficient solution: they typically contain too much data to be read in a few minutes preceding the show, and after the performance they are usually thrown away. More crucial, printed information cannot be synchronized with the ongoing show, and the spectator has to constantly connect the data on the paper with what is happening on the stage. Technology can overcome this problem. Interactive Concert Programs (ICP) is a software that allows the streaming of digital information (such as text, images, or links) to the mobile devices of an audience in real time. Data can be triggered at a specific moment, according to what is performed. Moreover, any spectator can autonomously navigate the information streamed, using his/her device. ICP combines the characteristics of a slideshow software such as PowerPoint, and of a hypertext, such as HTML pages. There are several advantages of using ICP instead of printed programs. The listening experience can be guided with relevant information through all the duration of the show. Multilingual translations can be easily provided, as well as explaining texts for the Deaf. Users can save and share on social media the most interesting information, thus engaging new potential public. Lastly, the editing process of concert programs would be drastically simplified, and with a remarkable saving of printed paper. In this historical moment when performing arts can be difficult to understand and be appreciated, ICP can easily and inexpensively turn any theater or stage into a big lecture room, providing a new effective way for artists to tell the audience their artistic vision and the story behind the artwork performed. The audience would assimilate information more easily, with a better understanding and appreciation of the shows."

First, we present a new dataset we constructed by cross-referencing data from such platforms. We then demonstrate how this dataset can be used to mine and predict important career milestones for the musicians, such as signing by a major music label, or performing at a certain venue. Finally, we perform a temporal analysis of the bipartite artist-venue graph, and demonstrate that high centrality on this graph is correlated with success."

Existing methods utilize the observed edges in the network to model the interactions between nodes and learn representations which explain the behavior. In addition to the presence of edges, networks often have information which can be used to improve the embedding. For example, in author collaboration networks, the bag of words representing the abstract of co-authored paper can be used as edge attributes. In this paper, we propose a novel approach, which uses the edges and their associated labels to learn node embeddings. Our model jointly optimizes higher order node neighborhood, social roles and edge attributes reconstruction error using deep architecture which can model highly non-linear interactions. We demonstrate the efficacy of our model over existing state-of-the-art methods on two real world data sets. We observe that such attributes can improve the quality of embedding and yield better performance in link prediction."

In this paper, we proposed a method that combines user click events within session and news contextual features to predict next click behavior of a user. The model consists of two different kinds of hierarchical neutral networks to learn article contextual properties and temporal sequential patterns in streams of clicks. Character-level embedding over input features is adopted to allow integrating different types of data and reduce engineering computation. Besides, we also introduced a time-decay method to compute the freshness of news articles within a time slide. Experimental results on two real-world datasets show significant improvements over several baselines and state-of-the-art methods on session-based neural networks.####[no references]"

Arguably the most prevalent contemporary form of IDN is within the world of computer games where a mixture of large-scale commercial works and smaller indie experimental pieces continue to develop new forms of interactive storytelling. We can explore these pieces through the lens of hypertextual theory and support them with hypertextual architectures, but there are unique challenges within modern game-based storytelling that these frameworks sometimes struggle to capture on a content level, leaving us in some cases with insufficient models and vocabulary. In this paper, we build upon previous work by presenting a discussion on techniques of modeling video game narrative. This is followed by thorough presentation and demonstration of our game-centric theoretical model of interactive narrative, Novella 2.0, which builds upon our previous contributions. This model is then positioned within a novel architecture for the authoring, interchange, integration, and simulation of video game narrative. We present alongside the architecture four key innovations towards supporting game narrative. We include support for Discoverable Narrative and other game narrative content alongside structural features in a deference of responsibility to game engines and our own approach to mixing calligraphic and sculptural hypertext structure."

However, there is a body of evidence of bias in the media caused by underlying political and socio-economic viewpoints. Previous studies have tried to classify the partiality of the media, sometimes giving a quantitative evaluation, but there is little reported on its nature. The vast amount of content in the social media enables us to quantify the inclination of the press to either side of the political spectrum. To describe such tendencies, we use tweets to automatically compute a news outlet’s political and socio-economic orientation. We show that the media have a measurable bias, and illustrate this by showing the favoritism of Chilean media for the ruling political parties in this country. We also found that the nature of the bias is reflected in the vocabulary used and the entities mentioned by different news outlets. A survey conducted among news consumers confirms that media bias has an impact on the coverage of controversial topics and that this is perceivable by the general audience. Having a more accurate method to measure and characterize media bias will clarify to the readers where outlets stand within the socio-economic landscape, even when a self-declared position is stated. This will empower readers to better reflect on the content provided by their news outlets of choice."

By analyzing human perceptions from residents of a mid-sized Brazilian city, this work brings three novel contributions. First, we consider theories from urban design to explore through crowdsourcing which high and low level features in an urban space are linked to perceptions of safety and pleasantness. Secondly, this paper leverages theory from urban sociology and anthropology to show how the sociodemographic profile of the citizens significantly mediate their perception of safeness and pleasantness of places. Finally, we show that features of the urban form proposed by urbanists can be combined with sociodemographics to improve the accuracy of machine learning models that predict which scene a person will find more safe or pleasant.

In addition, within such a complex data setting, each user-item pair may occur more than once, implying on repetitive preferential user behaviors. In this work we tackle the problem of building a Collaborative Filtering model that takes into account such complex datasets.

The privacy dilemmas associated with personalized services are particularly concerning in the context of social networking websites, wherein the privacy dichotomy problem is widely observed. To prevent potential privacy violations, businesses need to employ multiple safeguards beyond the current privacy settings of users. As a possible solution, companies can utilize user social footprints to detect user privacy preferences. To take a step towards this goal, we first ran a series of experiments to examine if the privacy preference attribute is homophilous in social media. As a result, we found a set of clues that users’ privacy preferences are similar to the privacy behaviour of their social contacts, signaling that privacy homophily exists in social networks. We further studied users located in different neighbourhoods with varying degrees of privacy and found a set of characteristics that are specific to public users located in private neighbourhoods. These identified features can be used in a predictive model to identify public user accounts that are intended to be private, supporting companies to make an informed decision whether or not to exploit one’s publicly available data for personalization purposes."

When evaluated on 13,087 apps (820,760 reviews), which we monitored over more than 6 months, Dolos identified 1,056 apps with suspicious reviewer groups. We report orthogonal evidence of their fraud, including fraud duplicates and fraud re-posts."

To design better web literacy practices for assessing online information, we need to understand how people perceive the credibility of unfamiliar websites under time constraints. Would they be able to rate real news websites as more credible and fake news websites as less credible? We investigated this research question through an experimental study with 42 participants (mean age = 28.3) who were asked to rate the credibility of various “real news” (n = 14) and “fake news” (n = 14) websites under different time conditions (6s, 12s, 20s), and with a different advertising treatment (with or without ads). Participants did not visit the websites to make their credibility assessments; instead, they interacted with the images of website screen captures, which were modified to remove any mention of website names, to avoid the effect of name recognition. Participants rated the credibility of each website on a scale from 1 to 7 and in follow-up interviews provided justifications for their credibility scores. Through hypothesis testing, we find that participants, despite limited time exposure to each website (between 6 and 20 seconds), are quite good at the task of distinguishing between real and fake news websites, with real news websites being overall rated as more credible than fake news websites. Our results agree with the well-known theory of “first impressions” from psychology, that has established the human ability to infer character traits from faces. That is, participants can quickly infer meaningful visual and content cues from a website, that are helping them make the right credibility evaluation decision."

Much of this spreading was enabled by new media formats, namely social networks and online media sites. Researchers and practitioners have been trying to answer this by characterizing the fake news and devising automated methods for detecting them. The detection methods had so far only limited success, mostly due to the complexity of the news content and context and lack of properly annotated datasets. One possible way to boost the efficiency of automated misinformation detection methods, is to imitate the detection work of humans. In a broader sense of dealing with fake news spreading, it is also important to understand the news consumption behavior of online users. In this paper, we present an eye-tracking study, in which we let 44 participants to casually read through a social media feed containing posts with news articles. Some of the presented articles were fake. In a second run, we asked the participants to decide on the truthfulness of these articles.

As a result, aside from conventional social media sites like Facebook and Twitter, platform designers introduced many alternative social media platforms (e.g., 4chan, Whisper, Snapchat, Mastodon) to serve specific userbases. Among these platforms, anonymous social media sites like Whisper and 4chan hold a special place for researchers. Unlike conventional social media sites, posts on anonymous social media sites are not associated with persistent user identities or profiles. Thus, these anonymous social media sites can provide an extremely interesting data-driven lens into the effects of anonymity on online user behavior. However, to the best of our knowledge, currently there are no publicly available datasets to facilitate research efforts on these anonymity effects.####To that end, in this paper, we aim to publicly release the first ever large-scale dataset from Whisper, a large anonymous online social media platform. Specifically, our dataset contains 89.8 Million Whisper posts (called “whispers”) published between a 2-year period from June 6, 2014 to June 6, 2016 (when Whisper was quite popular). Each of these whispers contained both post text and associated metadata. The metadata contains information like coarse-grained location of upload and categories of whispers. We also present preliminary descriptive statistics to demonstrate a significant language and categorical diversity in our dataset. We leverage previous work as well as novel analysis to demonstrate that the whispers contain personal emotions and opinions (likely facilitated by a disinhibition complex due to anonymity). Consequently, we envision that our dataset will facilitate novel research ranging from understanding online aggression to detect depression within online populace."

In this paper, we conduct a systematic analysis aimed at identifying key characteristics in user profiles that might lead to miscalibrated recommendations. We consider several categories of profile characteristics, including similarity to the average user, propensity towards popularity, profile diversity, and preference intensity. We develop predictive models of miscalibration and use these models to identify the most important features correlated with miscalibration, given different algorithms and dataset characteristics. Our analysis is intended to help system designers predict miscalibration effects and to develop recommendation algorithms with improved calibration properties."

On the other hand, we usually have to deal with lower volumes of objects, which are easier to discover by users through various browsing/searching GUIs.####The main goal of this paper is to determine applicability of off-line evaluation metrics in learning true usability of recommender systems (evaluated on-line in A/B testing). In total 800 variants of recommenders were evaluated off-line w.r.t. 18 metrics covering rating-based, ranking-based, novelty and diversity evaluation. The off-line results were afterwards compared with on-line evaluation of 12 selected recommender variants and based on the results, we tried to learn and utilize an off-line to on-line results prediction model.####Off-line results shown a great variance in performance w.r.t. different metrics with the Pareto front covering 64% of the approaches.

A large number of positive cases arising out of the religious Tablighi Jamaat gathering has driven people towards forming anti-Muslim communities around hashtags like #coronajihad, #tablighijamaatvirus on Twitter. In addition to the online spaces, the rise in Islamophobia has also resulted in increased hate crimes in the real world. Hence, an investigation is required to create interventions. To the best of our knowledge, we present the first large-scale quantitative study linking Islamophobia with COVID-19.####In this paper, we present CoronaBias dataset which focuses on anti-Muslim hate spanning four months, with over 410,990 tweets from 244,229 unique users. We use this dataset to perform longitudinal analysis. We find the relation between the trend on Twitter with the offline events that happened over time, measure the qualitative changes in the context associated with the Muslim community, and perform macro and micro topic analysis to find prevalent topics. We also explore the nature of the content, focusing on the toxicity of the URLs shared within the tweets present in the CoronaBias dataset. Apart from the content-based analysis, we focus on user analysis, revealing that the portrayal of religion as a symbol of patriotism played a crucial role in deciding how the Muslim community was perceived during the pandemic.

We conducted a preregistered, between-subjects crowdsourced user study (N=328) comparing six groups: three levels of obfuscation (targeted, random, none) and two levels of task (joint, two separate) for four debated topics. We found that both types of obfuscation influence user interactions, and in particular that targeted obfuscation helps decrease interaction with attitude-confirming search results. Future work is needed to understand how much of the observed effect is due to the strong influence of obfuscation, versus the warning label or the task design. We discuss design guidelines concerning system goals such as decreasing consumption of attitude-confirming search results, versus nudging users toward a more analytical mode of information processing. We also discuss implications for future work, such as the effects of interventions for confirmation bias mitigation over repeated exposure. We conclude with a strong word of caution: measures such as obfuscations should only be used for the benefit of the user, e.g., when they explicitly consent to mitigating their own biases."

Although a variety of theories propose to explain the processes of online radicalization, less work has empirically examined how users' communication patterns change over time, especially in terms of novelty versus regularity of user comment features. The present research demonstrates a new modeling approach for examining the extent to which low-level, multimodal comment patterns evolve as users communicate within a Reddit forum well-known for its extreme misogynism. Our results confirm that low-level comment patterns predict high-level features of radicalization, aligning with theory on attitude polarization and contributing to literature on detection and interventions to mitigate extremism."

This has led to a monolithic view of authoring, which has hindered tool design, resulting in tools that can lack focus, or ignore important parts of the creative process. In order to understand how authors practise writing, we conducted semi-structured interviews with 20 interactive narrative authors. Using a qualitative analysis, we coded their comments to identify both processes and challenges, and then mapped these against each other in order to understand where issues occurred during the authoring process. In our previous work we were able to gather together a set of authoring steps that were relevant to interactive narratives through a review of the academic literature. Those steps were: Training/Support, Planning, Visualising/Structuring, Writing, Editing, and Compiling/Testing. In this work we discovered two additional authoring steps, Ideation and Publishing that had not been previously identified in our reviews of the academic literature - as these are practical concerns of authors that are invisible to researchers. For challenges we identified 18 codes under 5 themes, falling into 3 phases of development: Pre-production, where issues fall under User/Tool Misalignment and Documentation; Production, adding issues under Complexity and Programming Environment; and Post-production, replacing previous issues with longer term issues related to the narrative’s Lifecycle. Our work shows that the authoring problem goes beyond the technical difficulties of using a system, rather it is rooted in the common misalignment between the authors’ expectations and the tools capabilities, the fundamental tension between expressivity and complexity, and the invisibility of the edges of the process to researchers and tool builders. Our work suggests that a less monolithic view of authoring would allow designers to create more focused tools and address issues specifically at the places in which they occur."

Although screen readers support a multitude of shortcuts for navigating over a variety of HTML tags, it has been observed that blind users typically rely on only a fraction of these shortcuts according to their personal preferences and knowledge. Thus, a mismatch between a user’s repertoire of shortcuts and a webpage markup can significantly increase browsing effort even for simple everyday web tasks. Also, inconsistent usage of ARIA coupled with the increased adoption of styling and semantic HTML tags (e.g., <div>, <span>) for which there is limited screen-reader support, further make interaction arduous and frustrating for blind users.####To address these issues, in this work, we explore personalized annotation of webpages that enables blind users to efficiently navigate webpages using their preferred shortcuts. Specifically, our approach automatically injects personalized ‘annotation’ nodes into the existing HTML DOM such that blind users can quickly access certain semantically-meaningful segments (e.g., menu, search results, filter options, calendar widget, etc.) on the page, using their preferred screen-reader shortcuts. Using real shortcut profiles collected from 5 blind screen-reader users doing representative web tasks, we observed that with personalized annotation, the interaction effort can be potentially reduced by as much as 48 (average) shortcut presses."

With the identified shared users across networks, it will provide researchers with the opportunity to achieve a more comprehensive understanding of users’ social activities both within and across networks. Social network alignment is a very difficult problem. Besides the challenges introduced by the network heterogeneity, the network alignment can be reduced to a combinatorial optimization problem with an extremely large search space. The learning effectiveness and efficiency of existing alignment models will be degraded significantly as the network size increases. In this paper, we focus on studying the scalable heterogeneous social network alignment problem and propose to address it with a novel two-stage network alignment model, namely Scalable Heterogeneous Network Alignment (SHNA). Based on a group of intra- and inter-network meta diagrams, SHNA first partitions the social networks into a group of sub-networks synergistically. Via the partially known anchor links, SHNA can extract the partitioned sub-network correspondence relationships. Instead of aligning the complete input network, SHNA proposes to identify the anchor links between the matched sub-network pairs, while those between the unmatched sub-networks will be pruned to effectively shrink the search space. Extensive experiments have been done to compare SHNA with the state-of-the-art baseline methods on a real-world aligned social networks dataset. The experimental results have demonstrated both the effectiveness and efficiency of SHNA in addressing the problem."

However, a systematic summarization-based narrative extraction that can facilitate communicating the main underlying events is lacking. To address this issue, we propose a novel event-based narrative summary extraction framework. Our proposed framework is designed as a probabilistic topic model, with categorical time distribution, followed by extractive text summarization. Our topic model identifies topics’ recurrence over time with a varying time resolution. This framework not only captures the topic distributions from the data, but also approximates the user activity fluctuations over time. Furthermore, we define significance-dispersity trade-off (SDT) as a comparison measure to identify the topic with the highest lifetime attractiveness in a timestamped corpus. We evaluate our model on a large corpus of Twitter data, including more than one million tweets in the domain of the disinformation campaigns conducted against the White Helmets of Syria. Our results indicate that the proposed framework is effective in identifying topical trends, as well as extracting narrative summaries from text corpus with timestamped data."

This work is based on the assumption that the formation of values (personal and societal) and language are interrelated, and that we can observe differences in points of view in user-generated text data. We leverage the Moral Foundations Theory to expand the scope of stance analysis by examining the narratives in favor or against several topics. Applying an expanded version of the Moral Foundations Dictionary to a benchmark dataset for stance analysis, we capture and analyze the relationships between moral values and polarized online discussions. Using this enhanced methodology, we find that each social issue has different “moral and lexical profiles.” While some social issues project more authority related words (Donald Trump), others consists of words related to care and purity (abortion and feminism). Our correlation analysis of stance and morality revealed notable associations between stances on social issues and various types of morality, such as care, fairness, and loyalty, hence demonstrating that there are certain morality types that are more attributed to stance classification than others. Overall, our analysis highlights the usefulness of considering morality when studying stance. The differences observed in various viewpoints and stances highlights linguistic variation in discourse, which may assist in analyzing cultural values and biases in society."

Associative linking is at best added value and at worst irrelevant to most Web sites. Search engines are the dominant means of finding information, but everyone is aware of their limitations. This is all set to change as we move into the world of pervasive computing and increasingly access the internet through hand-held devices. Agent technology will become the dominant means of building distributed information management systems. This together with the development of the Semantic Web will enable us to build environments which provide users with highly personalized and adaptive global information spaces to navigate through. The presentation will consider the role of hypermedia in such environments will there be more links or less? The answer is of course 42.####[no references]"

As a direct result of this, open hypermedia systems have been increasingly successful in providing middleware services such as linking to a large set of clients. This paper presents a new approach to service provision in open hypermedia systems based on the concept of multiple open services. The overall idea with multiple open services is to rethink the way in which services are provided to clients. The goal is to split up services into components, each of which provides a general, scalable, and functionally independent (orthogonal) service. This results in a highly flexible architectural framework that can serve as a vehicle to further investigate many of the open issues relating to open hypermedia systems. The approach can be viewed as a natural next step in the evolution towards more open, distributed, and modular hypermedia systems. The concept of multiple open services is described in detail, and a proof of concept implementation called Construct is presented."

A web community is a collection of web pages created by individuals or any kind of associations that have a common interest on a specific topic. In this paper, we propose a technique to create a web community chart, that connects related web communities, from thousands of seed pages. This allows the user to navigate through related web communities, and can be used for a ‘What’s Related Community’ service that provides not only the web community including a given page but also related web communities. Our technique is based on a related page algorithm that gives related pages to a given page using only link analysis. We show that the algorithm can be used for creating the chart by applying the algorithm to each seed, then using similarities of the results to classify seeds into clusters and to deduce their relationships. We perform experiments to create a web community chart of companies and organizations from thousands of seed pages. First, we improve the precision of an existing related page algorithm, Companion, and evaluated the improved version, Companion-, by an user study. Then the chart is created using Companion-. The result chart consists of web communities including related pages, and paths between related web communities. From the chart, we can find many web communities of companies classified by their category of business, and relationships between the communities."

Users express categories and interrelationships through the visual similarity and co-location of information objects. The ease of changing a visual property or moving an object makes spatial hypertext better suited to tasks where the information continually evolves. But the implicit nature of the structure poses challenges for tasks in which the authors and readers are not the same set of people. The Visual Knowledge Builder (VKB) includes the ease of expression of earlier spatial hypertexts while adding greater support for long-term collaboration and tasks requiring explicit links. VKB includes a history mechanism that records the evolution of the spatial hypertext and local, global, and historical links for explicit navigational connections between chunks of information. The mechanisms added to VKB make spatial hypertext applicable in a much wider variety of tasks. In particular, VKB’s global links enable wide-area distributed spatial hypertext using the existing infrastructure of the Internet. Versions of VKB have been in use for two years in tasks including note taking, writing, project management, and conference organization."

The similarity to knowledge representations such as frames and semantic nets has led to much effort in using hypertext systems for knowledge representation and extending hypertext systems to make them able to express more. This work has met with limited success due to difficulties including the tacit and situated nature of much knowledge. Instead of viewing knowledge expression as an all at once event, we view it as a constructive process, i.e. knowledge building. The Visual Knowledge Builder (VKB) lets users express content via visual or textual means and later formalize that content in the form of attributes, values, types, and relations. VKB proactively supports this process through a set of suggestion agents whose interaction with the user is mediated by the suggestion manager. Preliminary evaluation of the suggestion manager and suggestion agents yields positive results but further confirms that there is no “silver bullet” for knowledge engineering—semantic expression is most likely to happen during, and is driven by, task performance."

This panel seeks to address questions pertaining to authorship and tools for the sculptural approach to hypertext. Among the questions we want to address are: How does one write a sculptural hypertext? How does this concept scale - or is it only suited to small works? What differences are there for the reader of a sculptural hypertext vs. a calligraphic hypertext? How does the “subtractive” concept work with other models of hypertext than the node-link model, e.g. spatial hypertext?

The resulting presentations must both respect the underlying semantics and appear as coherent, plausible and, if possible, pleasant to the user. Among the related unsolved problems is the inclusion of discourse knowledge in the generation process. One potential approach is generating a discourse structure derived from generic processing of the underlying domain semantics, transforming this to a structured progression and then using this to steer the choice of hypermedia communicative devices used to convey the actual information in the resulting presentation. This paper presents the results of the first phase of the Topia project, which explored this approach. These results include an architecture for this more domain-independent processing of semantics and discourse into hypermedia presentations.

In this paper we present new techniques for identifying and working with such compound documents, and the results of some large-scale studies on such web documents. The primary motivation for this work stems from the fact that information retrieval techniques are better suited to working on documents than individual hypertext nodes."

Paths have long been recognized as an effective medium for aggregating and communicating information and have been included in various hypermedia systems as alternate metaphors or supporting tools. The Walden’s Paths project promotes path-centric traversal as the primary browsing mechanism over Web-based materials. This paper expands the notion of our paths to include more generalized structures and interconnections across paths. We present an architecture for describing complex networks of such paths. Finally, we discuss the design and present a prototype implementation of the Path Engine, a tool that provides a linear interface for browsing intricately interconnected paths."

We are exploring the combination of these modes of expression in Hyper-Hitchcock, a hypervideo editor. Hyper-Hitchcock supports a form of hypervideo called “detail-on-demand video” due to its applicability to situations where viewers need to take a link to view more details on the content currently being presented. Authors of detail-on-demand video select, group, and spatially arrange video clips into linear sequences in a two-dimensional workspace. Hyper-Hitchcock uses a simple spatial parser to determine the temporal order of selected video clips. Authors add navigational links between the elements in those sequences. This combination of navigational and spatial hypertext modes of expression separates the clip sequence from the navigational structure of the hypervideo. Such a combination can be useful in cases where multiple forms of inter-object relationships must be expressed on the same content."

This paper examines how the core differences in control assumptions between monolithic hypertext systems, open hypermedia systems, and the Web, lead to different incentive structures for readers and content providers and hence varying levels of network effects.####Significant results of this analysis are as follows. First, lack of control over the data in a hypermedia system, combined with a large-scale distribution infrastructure is a key aspect of achieving network effects, since this control choice affords large numbers of readers. Second, examination of network effects from the Web and monolithic hypermedia systems suggests that control over the user interface is a key contributor to network effects, since it provides a more pleasant experience for readers, and allows for more control over the presentation by content providers. Finally, control over the hypermedia structure provides a negative contribution to network effects, since the control point limits scalability, thus capping the total number of readers."

With both fields using much different approaches in what is ostensibly the same area, researchers often feel more need to justify their approach over others instead of looking for ways to synthesize their results. In this paper, we consider two “extremist” positions that caricature/characterize points of view held by some members of these fields, allowing each field to “make its case” as the “true” home of hypermedia systems research. We then reconcile these radically different perspectives, and in doing so, propose a framework that makes more apparent the contributions of each field and that we feel forms a basis for more fruitful cooperation."

In particular, we want to examine hypertext structure in the light of a combinatorial calculus. Such a combinatorial calculus is what postmodcrn fiction has drawn from Borges’s original idea of the labyrinth and the interconnection of multiple paths. It determines the multiple potential ways to connect lexias and the reading agreement between reader and author which results from such a combinatorial structuring. Ultimately, the author’s writing strategy is revealed by this combinatorial embedding."

But unlike most other hypermedia applications, an adaptive hypermedia system maintains a user model and changes the content and presentation of the information contained in the nodes on the fly, as well as the presentation of link anchors.#### An important first question that arises is: Are “adaptive hypermedia applications” “hypermedia applications”?#### Shneiderman and Kearsley [SK891 define a hypertext as a database that has active cross-references and allows the reader to “jump” to other parts of the database as desired. Adaptive hypermedia applications satisfy this definition even more than non-adaptive ones, because the adaptation is intended to increase the chances of letting the reader jump to desired places. Indeed, adaptation tries to guide the user towards interesting, relevant information, and shields the user from uninteresting, non-relevant stuff.####This panel will discuss some methods and techniques in adaptive hypermedia.

Hypertext design and usability has traditionally concentrated upon navigation and/or orientation. The notion of travel extends navigation and orientation to include environment, mobility and the purpose of the travel task. The presence of travel aids are important for all users, but particularly so for those with a visual impairment. This paper presents the ground work for including travel into web design and usability metrics by presenting a framework for identifying travel objects and registering them as either cues to aid travel or obstacles that hinder travel for visually impaired users. The aim is to maximise cues and minimise obstacles to give high mobility as measured by the mobility index. This framework is based upon a model of real world travel by both sighted and visually impaired people, where travel objects are used for orientation, navigation, route planning and survey knowledge. Knowledge of the differences in travel between visually impaired and sighted people will enable the model to be used in assisting the design of better user agents and web content for visually impaired and other users."

Our approach consists of integrating existing infrastructure mechanisms that are already used by numerous applications. We believe that integrating an underlying infrastructure can provide a basic level of hypermedia functionality to client applications while reducing the level of effort required of application developers. We present issues encountered in performing client-integration-in-the-large, discuss an experimental prototype of a specific infrastructure integration, and describe related work in this area."

Large Web sites tend to yield many matches that leads to a few large, flat structured, and unorganized clusters. As a matter of fact, these sites contain Web sites of other entities, such as projects and people. Many pages in these sites are actually “logical domains” by themselves. For example, Web sites for projects at a university or the XML section at W3C could be viewed as “logical domains”. In this paper, we propose the concept of logical domain with respect to physical domain which is identified simply by domain name. We have developed and implemented a set of rules based on link structure, path information, document metadata, and citation to identify logical domain entry pages and their corresponding boundaries. Experiments on real Web data have been conducted to validate the usefulness of this technique."

Among several strategies, two are discussed in detail with examples of applications. On the one hand, conceptual specifications for linking and assembling are embedded in the resource meta-description with the support of the ontology of the domain to facilitate meta-communication. Resources are like agents looking for conceptual acquaintances with intention. On the other hand, the domain ontology and an argumentative ontology drive the linking and assembling strategies."

We describe rules for making links and an experiment using two methods of applying those rules, to show how such rules should be evaluated, and to see if they truly help people. In addition to measures of performance we also collected measures of preference. The effectiveness of these links was evaluated by testing with people. Performance was determined by measuring the accuracy and inclusiveness of answers to questions about the article, and written summaries. Readers judged the quality of links (and thereby the quality of the rules used to forge them) and the overall effectiveness of the hypertext. Most readers did not read the entire articles in the time allotted. Readers had no preference for articles with or without novel link types, but they did have a strong preference for definition and structural links over (novel) semantic links. Readers of documents with only structural links had comprehension scores that were inversely proportional to their satisfaction ratings. No performance difference was detected."

This paper argues that our best response to this situation is to adopt the approach taken with other terms that are central to intellectual communities (such as “natural selection,” “communism,” and “psychoanalysis”), a historical approach. In the case of “hypertext” the term began with Theodor Holm (“Ted”) Nelson, and in this paper two of his early publications of “hypertext” are used to determine its initial meaning: the 1965 “A File Structure for the Complex, the Changing, and the Indeterminate” and the 1970 “No More Teachers’ Dirty Looks.” It is concluded that hypertext began as a term for forms of hypermedia (human-authored media that “branch or perform on request”) that operate textually. This runs counter to definitions of hypertext in the literary community that focus solely on the link. It also runs counter to definitions in the research community that privilege tools for knowledge work over media. An inclusive future is envisioned."

In this paper, we consider zzstructures, mSpaces, and polyarchies from the perspective of graph theory, and compare these models formally. The novel aspects of this work include: providing a sound, graph-theoretic analysis of zzstructures; the identification of a new class of polyarchies associated with mSpaces; and the comparison and classification of these and other structures within a taxonomy. The taxonomy that results from our comparison allows us to consider, first; what the distinct characteristics of each model are at a fundamental level, and second; what model or attributes of a model may be most appropriate for the design goals of a given hypermedia application.####[Special Research Distinction for Excellent Presentation of Theoretical Concepts]"

This opens up a wider spectrum of possibilities of intervention if the author exploits adaptive techniques in hypertext narrative. The paper intends to investigate how adaptivity is used in hyperfiction and to propose an interpretative grid for better understanding and future use."

Primarily tackling hypertext discourse coherence in the non-linear medium, CH is conceived as a way of thinking the hypertext medium that is consistent with its characteristics. CH envisages the consistent and concurrent use of the medium’s formal features, grounded in structuring principles, in order to allow the emergence of a local language. Relational primitives based on Cognitive Coherence Relations are proposed as a structuring principle to define hypertext links, while the use the medium’s graphic features is proposed to render these relational primitives as patterns that will take shape during navigation. Taking scholarly hypertext as a domain, this paper articulates the theoretical basis for cinematic hypertext, presents the elements of a prototype visual language to express a sub-set of CCR, provides experimental evidence of its significance, and finally envisages the realisation of a cinematic hypertext environment."

WebRelievo aligns these graphs according to their time, and automatically determines their layout keeping positions of nodes synchronized over time, so that the user can keep track pages and clusters. This visualization enables us to understand when pages appeared, how their relationships have evolved, and how clusters are merged and split over time. Current implementation of WebRelievo is based on six Japanese web archives crawled from 1999 to 2003. The user can interactively browse those graphs by changing the focused page and by changing layouts of graphs. Using WebRelievo we can answer historical questions, and to investigate changes in trends on the Web. We show the feasibility of WebRelievo by applying it to tracking trends in P2P systems and search engines for mobile phones, and to investigating link spamming."

It is not visible in the movie frame how long a film is, so stretchfilm requires an extra visualization of how stretched out or shrunk the film currently is.####Structure and Cognition. Stretchfilm is only easy to use if the editing makes the user understand what will come next, so he or she can choose to stretch or shrink based on this understanding.####Other Genres.

In this paper, we examine how communities can be discovered through interconnected blogs as a form of social hypertext [14]. We propose a method and model that detects structures of community in the social network of blogs by integrating McMillan and Chavis’ sense of community [26] along with network analysis [8, 11]. From the model, we measure community in the blogs by aligning centrality measures from social network analysis [17] with measures of sense of community obtained using behavioural surveys. We then illustrate the use of this approach with a case study built around an independent music blog. The strength of community measures were found to be well aligned with the network structure, based on centrality measures. Even though the sample size from the case study was small, once the structure and measure of communities are calibrated according to our social hypertext model, communities can be automatically found and measured for other blogs without the need for behavioural surveys."

Tagging systems have the potential to improve search, spam detection, reputation systems, and personal organization while introducing new modalities of social communication and opportunities for data mining. This potential is largely due to the social structure that underlies many of the current systems. Despite the rapid expansion of applications that support tagging of resources, tagging systems are still not well studied or understood. In this paper, we provide a short description of the academic related work to date. We offer a model of tagging systems, specifically in the context of web-based systems, to help us illustrate the possible benefits of these tools. Since many such systems already exist, we provide a taxonomy of tagging systems to help inform their analysis and design, and thus enable researchers to frame and compare evidence for the sustainability of such systems. We also provide a simple taxonomy of incentives and contribution models to inform potential evaluative frameworks. While this work does not present comprehensive empirical results, we present a preliminary study of the photo-sharing and tagging system Flickr to demonstrate our model and explore some of the issues in one sample system.

Small groups of kids—working both shoulder to shoulder and remotely—can explore together multimedia interactive stories rendered by means of 2D and 3D scenes; they can perform a variety of educational games and narrative activities; they can personalize scene elements and collaboratively create their own narrative flows, generating a multidimensional (i.e., 2D and 3D) hyperstory from the linear multimedia stories that are built-in in the system.

Based on this material, we propose concepts for collectional actions and meta-data actions, and present prototypes combining principles from augmented reality and hypermedia to support organising and managing mixtures of digital and physical materials. The prototype of the tagging system is running on digital desks and walls utilizing Radio Frequency IDentifier (RFID) tags and tag-readers.

It is now an exciting challenge for us to observe evolution of the Web. In this paper, we propose a method for observing evolution of web communities. A web community is a set of web pages created by individuals or associations with a common interest on a topic. So far, various link analysis techniques have been developed to extract web communities. We analyze evolution of web communities by comparing four Japanese web archives crawled from 1999 to 2002. Statistics of these archives and community evolution are examined, and the global behavior of evolution is described. Several metrics are introduced to measure the degree of web community evolution, such as growth rate, novelty, and stability. We developed a system for extracting detailed evolution of communities using these metrics. It allows us to understand when and how communities emerged and evolved. Some evolution examples are shown using our system."

As sites are created for different purposes, their structure and connectivity characteristics vary. However, this research argues that sites of similar role exhibit similar structural patterns, as the functionality of a site naturally induces a typical hyperlinked structure and typical connectivity patterns to and from the rest of the Web. Thus, the functionality of Web sites is reflected in a set of structural and connectivity-based features that form a typical signature. In this paper, we automatically categorize sites into eight distinct functional classes, and highlight several search-engine related applications that could make immediate use of such technology. We purposely limit our categorization algorithms by tapping connectivity and structural data alone, making no use of any content analysis whatsoever. When applying two classification algorithms to a set of 202 sites of the eight defined functional categories, the algorithms correctly classified between 54.5% and 59% of the sites. On some categories, the precision of the classification exceeded 85%. An additional result of this work indicates that the structural signature can be used to detect spam rings and mirror sites, by clustering sites with almost identical signatures."

The Semantic Web is portrayed as: (1) a universal library, to be readily accessed and used by humans in a variety of information use contexts; (2) the backdrop for the work of computational agents completing sophisticated activities on behalf of their human counterparts; and (3) a method for federating particular knowledge bases and databases to perform anticipated tasks for humans and their agents. Each of these perspectives has both theoretical and pragmatic entailments, and a wealth of past experiences to guide and temper our expectations. In this paper, we examine all three perspectives from rhetorical, theoretical, and pragmatic viewpoints with an eye toward possible outcomes as Semantic Web efforts move forward."

It hopes to show a convergence of the two into a working system for analysing dance in a network of people, institutions and information. The Associative Writing Framework (AWF) project seeks to explore how writers could best be supported in representing and exploring hypertextuality in a Web environment, and in producing new hypertexts which integrate or “glue together” existing Web resources (ideas, concepts, data, descriptions, experiences, claims, theories, suggestions, reports, etc.). Following the combining of the two projects we report on some initial evaluation of the AWF system by dance experts, and discuss where the relationship might lead and potential future outcomes of the collaboration."

IUHM emerged as a result of the development of the OPALES system, a collaborative environment for exploring and indexing video archives in a digital library. A basic design requirement of OPALES is that it must permit and support the integration of new services throughout its life cycle. Thus, IUHM depends heavily upon the notions of extensibility and openness. Support for openness, extensibility and late binding of services is provided in the IUHM model by a single reflexive mechanism. This uniform mechanism is used for describing all relationships between arbitrary system entities, including services, data and metadata. The mechanism in question consists of a generic, computable hypertext structure with typed links, known as the Information Unit (IU), and is the minimal structural scheme to which all encapsulated entities comply. We describe and justify the design of the Information Unit, as well as the semantics of its four link types, namely role, type, owner, relative. We further describe the minimal kernel of the runtime layer responsible for the dynamic behaviour specified by the IUHM compliant hypertext network. We discuss the mechanisms involved in the dynamic binding of services and service composition. We illustrate these notions by real-world examples of the integration of metadata services within the OPALES system."

Within structural computing, “structure” refers to a combination of data together with relationships pertaining to that data. Structure servers support the specification and manipulation of structures. One important aspect of structural computing is the power and flexibility it provides application developers constructing new applications. A large part of this power is due to structural computing’s ability to provide awareness services for both structure and behavior. We define this concept and describe the awareness services provided by the Themis structural computing environment. The utility of these services are demonstrated by presenting the impact they have had on the InfiniTe information integration environment. In particular, these services help to increase the efficiency and reduce the size of domain-specific applications built using structural computing technology. We conclude by discussing how these services might influence the open hypermedia field and the development of new hypermedia services."

An alternative approach that provides better support for ambiguity and adaptability is instantiated in FLAPS, an adaptive spatial parser that uses fuzzy-logic in order to infer the implicit structure of spatial hypermedia.

Furthermore, domains where hypertext already plays an important role (e.g., document preparation, idea management, design problem solving, decision making and argumentation, teaching and training) are or will soon become high priority topics for CSCW applications. There is no doubt that hypertext systems have to become multi-user systems and have to be extended by appropriate capabilities (e.g. shared screens, locking mechanisms in the hyperdocument base, versioning, knowledge-based components for monitoring access and changes by different users and reporting this on the basis of defined rules, etc.). On the other hand, CSCW is lacking a clear concept about which types of “document” structures and formats are needed as an appropriate communication medium for cooperation and collaboration.####The goal of this panel is to provide an interactive forum to discuss the relationship between hypertext as it is conceived and implemented today and requirements of current and future CSCW situations and applications. Panelists from both communities will provide their differing perspectives on the relationship between the fields and their mutual impact. In order to address a number of specific issues within this general framework, the moderator suggested the following seven sets of questions and posed them to the panelists."

Hypertext is the preferred medium for delivering complex and dynamic information because it provides a self-explanatory interface, facilitates direct searching and also encourages more general exploration, via browsing facilities. However the hypertext systems currently available do not provide proper tools for administrators of larger databases. Thus, we designed and implemented a system comprising two components: a relational back-end database and an hypertextual front-end. The back-end is designed to address the needs of database administrators: a robust and fast database management engine for data entry and update with consistency checks, flexible reporting and printing, and multiuser access. The front-end is published and distributed periodically via floppy disk to users, who need a fast, easy-to-install and easy-to-use read-only environment for browsing and searching information.####[no references]"

Written in the X Window System, the VNS/X (demonstrated here) was originally designed around the metaphor of the lab researcher’s notebook. VNS manages notebooks and pages which hold information objects. Objects may be images, text, audio, pointers to programs and other files, and links to other pages and notebooks. Text and images can be captured from arty other window or program on the user’s display and placed on a notebook page. The VNS supports the simultaneous manipulation of pages and real-time conferencing.####The hypermedia nature of the VNS allows users to create navigational links between notebook pages and action links from notebook pages to external programs. Thus, notebook pages are not limited to sequential order, but may be interconnected in any fashion to forma web of information or knowledge. Action links perform tasks external to the notebook, such as launching external programs which may display in windows next to the VNS, playing audio files, controlling video equipment, etc. A key feature of the VNS is its ability to capture data from other windows. Data may be interchanged among the external programs and notebook pages with simple copy and paste operations.####[no references]"

Other senses, sound and touch, although given roles, are clearly quite secondary. What VR presents to the user is images, not texts. What role might text play in Virtual Reality? This is particularly important for exponents of hypertext, because VR threatens to become the hot new topic, and perhaps to diminish interest and research in hypertext. One could convincingly argue there is no real direct competition: VR and hypertext can evolve side by side for different purposes. VR is useful for simulation and training, for medical imaging, for telepresence, and so on. Hypertext serves for databases of text materials, pedagogy, and interactive fiction and nonfiction. But even if VR and hypertext continue to evolve side by side, it remains interesting to consider how the two might merge.####Virtual Reality and hypertext are products of two different communication technologies. Virtual Reality has its closest affinity to television, which is a perceptual medium. Hypertext comes out of the tradition of writing. Both VR and hypertext claim to be new ways of expressing information, although with different emphases.####In VR, one sees and touches a perceptual space; in hypertext one reads and writes in a textual space. Can the two be combined? In particular, can the space of virtual reality be hypertextualized? One way to introduce text into virtual reality would be to write upon the surfaces in the virtual space. This would give us a virtual book, whose structure is expressed architecturally in three dimensions. The book becomes a space that the reader enters and explores, a space in which the relationships among the surfaces define relationships among the verbal ideas in the text. A more radical possibility y would be to turn the entire virtual space into a symbolic structure. Several hypertext systems are already moving in this direction: the concept maps in hypertext systems are examples of symbolic spaces in two dimensions. A third dimension would expand the possibilities of representation. Such a hypertextualized virtual space might allow the creation of text unlike any that have ever been written.####[no references]"

Empirical studies conducted so far have used various methods, and focused on a wide range of populations, types of documents, and reading or learning tasks. Although hypertext is generally associated with information networks, a few interesting studies address the issues of computer assistance to linear text comprehension. A second group of studies investigate the use of nonlinear documents for general learning purposes. Although these studies are mainly concerned with linear-nonlinear comparisons, some of them address the effects of different design options. Finally, a third group of studies compare information retrieval in linear versus nonlinear documents. Overall, there is no consistent evidence for the advantage of hypertext over linear presentation formats. Instead, the efficiency of nonlinear documents varies according to (a) subjects’ expertise (b) interface features and (c) task requirements. In an attempt to provide an interpretative framework for these empirical findings, the notion of cognitive monitoring is briefly outlined. I conclude with a few implications for future hypertext research."

Recent pragmatist arguments in intellectual history suggest that it is a matter of placing the text within some larger context, viewing it from a variety of perspectives, and “using it” to satisfy one’s own interests and purposes. What is the best means to “advanced knowledge acquisition”? Recent theories of learning in cognitive psychology suggest that we view “ill-structured knowledge domains” as landscapes, to be “criss-crossed” in a variety of directions, from multiple perspectives. Hypertext is a technology for doing both of these things. Quite independently, but sharing a foundation in pragmatism and the later Wittgenstein, each of these disciplines thus encourages further research in the development and implementation of hypertext systems for learning. Such research is being carried out in the Hypermedia Laboratory and the Cognitive Flexibility Laboratory at the University of Illinois, with implications for the way hypertext systems are designed and implemented, and the pedagogical problems to which they are applied."

The different instantiation and combinations of these constructs yield an open class of hyperdocuments. Nodes, anchors, and links are all considered first-class objects and modeling constructs are applicable to all of them.

Second, it allows asynchronous material, such as user interaction, links, or programs, to be combined with richly coordinated synchronous material in a single hypermedia document. The system incorporates a linear programming algorithm to solve the temporal constraints.

Because synchronization constraints record the author’s intentions and because the system creates schedules automatically, both creating documents and maintaining them throuughout their life cycles should be easier."

In principle, these allow linking across diverse applications and even across platforms. Rather than a monolithic hypermedia system presenting its own editors for various media, the user sees a framework into which existing editors can be “plugged” and a linking protocol with which to interconnect them. Though the framework is usually a separate program, the hope is that support for such open linking will one day migrate into the operating system. Indeed, protocols from Apple and Microsoft are steps in this direction.####Though the participants on this panel bring their own perspectives and backgrounds to the problem area, all share a belief that the future of hypermedia is not with systems that “own the world”, but with those that attempt to ‘(connect the world”. Furthermore, the panelists and the projects they represent have developed significant open hypermedia architectures and linking protocols and can draw on experience with real users.####Examples of questions we’ll be raising:####● What should be the minimum required of third-party applications that want to “play”. And how can we allow varying degrees of linking “awareness” across participating applications?####● Is consistent handling/appearance of links across applications important?

It’s pretty out there in infinity, but if you head out, how do you get home again?####Creative artists are still fumbling in this new space, this new medium, toying with the possibilities of multidimensionality, nonlinearity, interactivity, polyvocality, and, increasingly, the incorporation of other arts, visual, kinetic, and aural, but not yet convinced that narrative, as we lovingly know it, can overcome the motionsickness associated with the absence of gravity.####Most academic hypertext projects preserve a sense of gravity by allowing a body of informational satellites to circle loosely about some core subject, a poem, say, or an historical event, a social entity, a philosophical or legal problem, etc., and such models might well serve artistic projects but they cannot define or delimit them. Nor does it help to implant a line. All these centuries of resisting the tyranny of the line, and suddenly it is gone as though it never existed, but reinventing it, though an option for some, is a bit like building a road in outer space so we can take our cars out there,####Most narrative artists, for the moment, prefer to stay home where the environment’s friendly and there’s plenty of company. They still like the familiar paths with their beginnings, middles, and ends, even if not always traveled in that order. The navigational procedures are still so demanding out there in hyperspace, that there’s too little time to appreciate style, voice, eloquence, character, story. Links and maps seem more compelling than text, aa though the ancillas of book culture—the tables of contents, the indices and appendices, the designs and jackets and headers—might have swallowed up the stuff inside. There’s an appeal in interactivity—and a threat. And, maybe worst of all, where’s closure out there? How do you know when one journey’s over and another can begin?####So the field is largely left at present to the rash, the young, the enterprising. Flights are being made in vehicles that seem aa creaky at times as the tin spaceships of the old silent movies, and few of the adventures escape the atmosphere of print technology, but with each foray something new is added to the craft, the orbits widen, the manuals expand. Perhaps the greatest stimulus to these explorations is the promise of a multi-media instrument panel. Hyperspace may always be a bit hostile to the isolated traveler.

We show that attaching knowledge to anchors through types must take into account the context of use of the anchored text. Thus, we introduce the notion of semantic anchoring of concepts within documents. We show how Macweb makes it possible to implement this approach without adding any new features and how it provides an answer to the famous sentence “Don’t link me in”.

HyperSet, a hypermedia environment tailored for taxonomic reasoning [Parunak 91], is an example of this philosophy. People perform taxonomic reasoning when they classify, store, and retrieve a number of similar information objects (such as biological specimens, or linguistic constructions, or research projects). The process is essentially set-based. The user sorts objects into sets based on their characteristics; looks together at members of a single set to search for correlations or discernible subsets among them; examines the different sets of which one item is a member to see whether there are relations among them; and generates new sets from old ones.####Two years of experience in using HyperSet has led to a deeper understanding of the patterns and processes of taxonomic reasoning and the kind of computer methods that can effectively support it. This paper reports on three of these insights:####1. The set of sets that develops as classification takes place is not flat, but hierarchical. Analysis of this hierarchy yields a representation that combines the flexibility of a directed acyclic graph with the navigational properties of strict trees.####2. It is useful for a taxonomic information system to support a simple dualism between sets and their elements, permitting one to do set operations on artifacts as well as on sets.####3. Similarity measures among different sets are most usefully computed for a hypercube of such sets, a hypercube that emerges naturally from the hierarchical structure of sets."

Each link-resolving component is a set of cooperative processes, communicating with a central network manager. When a user points at some location within a window, each link-resolving component is given a key derived according to a previously-stored algorithm; the link-resolving components concurrently update their displays according to their algorithms for resolving the keys. Multiple applications can easily share a common source and be invoked simultaneously, providing a concurrent browsing mechanism. Two example hypertext employing this architecture are described."

A linked text structure is then created that relates similar texts at various levels of detail. In particular, text links are available for full texts, as well as text sections, paragraphs, and sentence groups. The linked structures are usable to identify important text passages, to traverse texts selectively both within particular documents and between documents, and to provide flexible text access to large text collections in response to various kinds of user needs.

The hypertext documents that these theorists envision (and create) are quite different from one another because they are based on each theorist’s particular perspective on hypertext. Recently, many hypertext theorists have acknowledged a need for hypertext authors to develop a better rhetorical understanding of their readers; however, the reader roles that most hypertext theorists have thus far anticipated do not encompass all of the reader roles that hypertext can accommodate. Coney (Cone92a) has offered a comprehensive “taxonomy of readers” that-although it was originally conceived as a taxonomy of readers of conventional print-provides deeper insight into hypertext reader roles. In this paper, we will discuss the philosophical traditions invoked by various hypertext theorists and the reader roles that are accommodated or required by those traditions. Finally, we will discuss the hypertext author’s virtual presence, the implied author, as a corollary of reader role."

It is not obvious where links should lead and there are no standard rules that indicate what should happen to other parts of the presentation that are active.####This paper addresses the problems associated with links in hypermedia. In order to provide a solution, we introduce the notion of context for the source and the destination of a link. A context makes explicit which part of a presentation is affected when a link is followed from an anchor in the presentation. Given explicit source and destination contexts for a link, an author is able to state the desired presentation characteristics for following a link, including whether the presentation currently playing should continue playing or be replaced.####We first give an intuitive description of contexts for links, then present a structure-based approach.

In particular, valuable context showing the relationships between the views is lost. By balancing local detail and global context, fisheye views display information at several levels of abstraction simultaneously.

We have explored spatially structured hypertext authored in three different systems, and have developed heuristic recognition algorithms based on the results of our analyses of the kinds of structures that people build. Our results indicate that (1) recognition of implicit structures in spatial hypertext is feasible, (2) interaction will be important in guiding such recognition, and (3) the hypertext system can provide layout facilities that will render later systematic interpretation much easier.

Macintosh and Unix/X versions have been prototype. The video shows the MS Windows version which is the most fully developed and has been integrated with several Windows applications.####Microcosm consists of a number of viewers which allow the user to view and interact with many different formats of information. The viewers communicate with Microcosm which then sends messages through a filter chain. Important filters are the link databases, or linkbases, In Microcosm, documents are not marked up internally: the link data is held in these separate link bases, and the viewers communicate with the linkbases to establish what buttons and links exist relevant to a particular document.####The Microcosm model allows a spectrum of link types. At one end of this spectrum are specific links or buttons which are manually authored links from a fixed source point to a destination point, Generic links are links that have a fixed destination but which may be followed from any point in any document where the appropriate object (such as a text selection) occurs. At the other end of the spectrum are computed links. These links are generated dynamically using information retrieval techniques, for example.####An important feature of Microcosm is the facility to dynamically install filters, particularly linkbases. It is common for a user to have at least two linkbases in the filter chain. One will be the application’s Iinkbase which will contain links made by the original author. Another will belong to the user, and will contain personal link information and annotations. It is thus possible to have one set of multimedia documents, with a number of different linkbases that might contain completely separate views on the same set of information. If required, a user could install more than one such linkbase at a time and use the union of these sets of links.####The Microcosm model provides a link service using which it is possible to follow links into and out of applications that are not part of Microcosm. Many Windows application packages have facilities that permit programmable communication with the Dynamic Data Exchange (DDE) and in this case it is possible to treat such an application as a Microcosm viewer. When it is not possible to communicate via the DDE, links can be followed by simply cutting and pasting a selection to the clipboard. The openness of the model, allows selections to be any data objects."

However, hypermedia system designers so far have been forced to assign many keywords or many links among objects in order to provide flexible and user-customized navigation. As a result, costs for organizing such systems rise accordingly, and it is difficult to apply this kind of alphanumeric approach directly to large-scale systems.####The translation from media information clues to alphanumeric representation is clearly a barrier for the interaction between the system and its users. Instead, users should Ibeable to directly make a query to the hypermedia using the same representation as the object they want to retrieve.####Media-based navigation is a new navigation style for hypermedia systems. Users can use media information clues in both browsing and querying phase.####Users retrieve objects using media information such as shape, color, motion, etc. This type of media-based retrieval becomes even more powerful as users can input the queries to the system as objects they perceive in the real world. The system, then, interprets the queries and shows possible candidates that match the query. Users browse these candidates, and show interesting objects to the system. The system finds all other objects that might be of interest to the user.####Miyabi is a prototype of a navigation-based hypermedia database system, It is based on an extended Entity-Relationship model and provides a wide variety of navigational tools such as schema browsers and media-based browsing tools. It is designed to clearly separate conceptual information from media processing so as to simplify its architecture. It is also designed to consider high level semantic structures to handle large amounts of hypermedia data.

Through these bees, the dead of the future begin to appear, introducing Jacob to a type of destiny that pushes him away from the normal world, enveloping him in a grotesque miasma of past and synthetic realities. The bees show Jacob the story of his grandfather’s acquisition and fatal association with the “Mesopotamian” bees, in the years following the First World War. The bees also lead Jacob away from his home, out to the Alamogordo desert, slowly revealing to him their synthetic/mechanical world, which exists in a darkness beyond the haze of his own thoughts.

All course readings were kept online in FRESS files that were accessible to the entire class. Student essays were handed by being linked to the material to be read. The instructor’s comments on the students’ work were also attached via links. The issues of file sharing for the class were simply addressed since there was only one graphics terminal capable of running the full FRESS interface. Thus all students had to go to specially scheduled lab times in order to do their readings and complete their assignments.####The information available to students was quite rich, even by contemporary standards. The primary texts were available online, as was a textbook describing a linguistic approach to the study of poetry. Assignments were quite carefully structured, with several phases of commentary and revision devoted to each work studied.####The second video is a demonstration of the FRESS system (actually running on the data files created by the poetry project). The basic FRESS program, despite being written in 360 assembly language, still runs more than 10 years after it was last compiled.

The main body of the material in Perseus consists of a large collection of primary texts with accompanying translation and notes, descriptions of archaeological objects with accompanying drawings and photographs, an atlas, an encyclopedia and a Greek-English lexicon, In addition, there are specialized tools for searching and navigating within the material as a hypertext.

As evaluation results indicated after Perseus 1.0 had been in use for a semester, it is not easy to incorporate an unfamiliar system like Perseus into traditional forms of teaching. In order to make effective use of Perseus, instructors must learn not only how the program works, they must also learn to perform tasks in new ways. The video has therefore become a useful part of the Perseus documentation.####The video was produced by Video Visuals of Newton, Mass. and was coordinated by Phinney Morrison of the Perseus Project."

This has led to interest in the concept of open hypermedia systems that are able to act as a link service to an existing set of applications. The key to this concept is in the perception of hypertext principles as a method for integration rather than simply as a delivery medium for a clearly defined information set.####A vision of the possibilities such a system might provide in a real world situation is given by Malcolm et al. [Malc91]. They paint a convincing picture of an environment where hypertext principles provide a seamless integration of a diverse range of applications. In order to provide such facilities in an efficient manner, a common link service such as described by Pearl [Pear89] and Rizk [Rizk92] is essential. This would provide a standard linking protocol that any application can take advantage of in order to become a fully integrated part of its environment. The Microcosm link service which we have been developing at the University of Southampton addresses the need for an integrating technology of this type."

The language—the result of over 20 years of ZOG/KMS development—is a procedural, block-structured language characterized by a simple ‘command line’ syntax, a large number of intrinsic commands (approximately 800), and the use of nodes and links as a central aspect of the syntax and semantics of the language. The intrinsic use of nodes and links in the script language provides interesting opportunities, not only for the design of other aspects of the language such as control structures, but also for the use of hypermedia as a programming environment to facilitate development and maintenance of scripts. In addition to designing the language, we have used it extensively to develop many hypermedia-based applications. Our experience, and that of end-user organizations, strongly reinforces our general belief that a script language is a valuable adjunct to hypermedia systems and instrumental to the utility of hypermedia for real world task environments.####[no references]"

As part of the argument, we present a theoretical design space for information structuring systems and locate existing hypertext systems within it. The dimensions of the space highlight a system’s internal representation of structure and the user’s actions in creating structure. Second, we describe an empirically derived range of activities connected to conducting group meetings, including the pre- and post-preparation phases, and argue that hyptetext systems need to be more flexible in order to support this range of activities. Finally, we describe a hypermedia prototype, DOLPHIN, which implements this kind of flexible support for meetings. DOLPHIN supports different degrees of formality (e.g., handwriting and sketches as well as typed nodes and links are supported), coexistence of different structures (e.g., handwriting and nodes can exist on the same page) and mutual transformations between them (e.g., handwriting can be turned into nodes and vice versa)."

It can support dynamically defined structures as well as inference capabilities, going beyond current static and passive hypertext systems. The expressive power of the language is a fundamental issue: too little power limits the applications of the language, while too much makes efficient implementation difficult and probably affects ease of use. The complexity and expressive power of GraphLog can be characterized precisely by using notions from deductive database theory and descriptive complexity. In this paper, from a practical point of view, we present examples of GraphLog queries applied to several different hypertext systems, providing evidence for the expressive power of the language, as well as for the convenience and naturalness of its graphical representation.

We present a knowledge-intensive assistant for building hypertext fragments from a knowledge base customised both explicitly and implicitly by a user. Such a presentation may clarify relationships between concepts that were present implicitly in multiple sources of information. In the domain of an intelligent information retrieval system, we show how such an assistant may render customised views of knowledge extracted in a manageable form.

The production of a written synthesis is a challenging task that requires managing large amounts of information over an extended period of time. Thus, synthesis writing is a task that is well-suited for testing the potential of hypertext technologies to support work on complex tasks. From a case study of experts and novices, we have developed a theory of the cognitive processes involved in producing a written synthesis. We have also developed a preliminary theory of the role of external representations in the writing process. We have drawn upon these two theories to design several hypertext-based external representations that we believe will augment writers’ performance on a written synthesis task. The hypertext-based applications include a general graph object and a table object; these objects form the foundation for a set of specialized tools to support synthesis writing, namely, a summary graph, synthesis grid and synthesis tree."

Driven by the needs of particular applications and by platform and market constraints, a plethora of competing and incompatible hypertext systems have arisen. Their user interfaces vary radically, from the fixed frames of KMS to the multiple scrolling texts of Guide. The data models are equally diverse, from the formalisms of HAM and Intermedia to HyperCard’s combination of object structure with procedural links. Many of these systems have already carved out substantial market niches and a growing amount of content is being created within their confines. Indeed, our ability to make global statements of utility for any of these approaches is still quite limited, and there may be no one best way of storing or presenting hypertext which suits all users and applications.####Compounding the problem is the emergence of the academic and commercial computing milieu as a distributed, loosely coupled collection of machines and networks of varying scale and vendor. In this environment, the emergence of a uniform hypertext storage sub-strate such as Xanadu is problematic and the difficulties of maintaining consistency across a large docuverse are compounded.####If we are not to abandon the vision of grand scale collaboration within the docuverse, some means of interchange and communication between hypertext systems becomes necessary. The requirement is equally pressing for potential publishers of hypertext based content, who must worry about portability of their works between hypertext systems and ensuring their longevity in the face of rapidly changing hardware and software platforms. Loss of either of these applications areas could be permanently crippling to the evolution of hypertext as a medium.####Steps toward interchange, standards, and ultimately distributed open hypertext systems must be founded on an abstract model of hypertext to which existing and future systems can be related. Creation of such a model forces us to go beyond casual references to “links” or “nodes” and to begin defining in a formal fashion the underpinnings of our field, building a lingua franca of hypertext.####[no references]"

In order to built systems that provide (intelligent) support for these activities cognitive processes and structures play a crucial role when designing hypertext systems. It can be observed that the construction of hypertext systems is often based on intuition and first-order task analysis. To overcome this situation, we need a user-oriented and task-driven approach to system design utilizing results of cognitive science or stimulating new research topics by looking at these applications.####The range of the topics of the panel will include the role of cognitive models of writing and reading for designing authoring tools in hypertext environments; critical issues of designing support for navigation in large information spaces including browsing and reading for the recipient; questions of how to arrive at cognitive compatibility of mental models of designers and users for the design of appropriate and cognitively adequate user-interfaces; compatibility of authors and readers; strategies of mapping knowledge representations on hyperstructures so that they can be processed later; the organization of multiple tasks extending to cooperative authoring and editing.[no references]"

By doing this we gain flexibility and provide a common framework allowing applications to share infor­mation and user interface capabilities.####The toolkit provides a simple hypermedia data model and an object-oriented user interface. The data model stores the underlying hypermedia structure and the application’s data. The user interface model separates the data and the view components of the objects, which permits the construction of interfaces independent of the final display platform. The combination of these two components provides a powerful toolkit capable of either adding a touch of hypermedia to an application or constructing a monolithic hypermedia system.####We describe the constraints of our development environments, our toolkit, and some typical applications of the toolkit, as well as our future plans."

We present a logical query language permitting the formulation of such structural queries over hypertext. While the language is propositional, it includes a general notion of quantifier of the form appropriate for hypertext networks. Quantifiers are used for expressing formulas of the form: “For most paths from the current node, claim X holds”.

The operative mechanism is termed a pair grammar, in which a string grammar and a graph grammar are paired in a one-to-one correspondence.

Examples are given an implementation of this technique using the timing mechanism in Trellis. In the technique, event durations in a document are altered without actually changing the links in the underlying Petri net. The two extrema of instantaneous events and infinite delays can be used to create apparent node and link deletions and additions, as well as to insert new tokens (loci of activity) into a document. Adaptation of these times is accomplished using a simple data state in which the event timings (and other document properties) are variables, called attributes. As a reader traverses hypertext links, author-supplied adaptation agents are invoked to collect information and possibly change the values of the attributes. Agents encapsulate and effect the criteria for deciding when, and specifically how, a structure should be adapted. Several practical examples illustrate the conclusion of this report: sophisticated alterations do not require a complicated adaptation mechanism, that changing document constants into document variables provides flexibility to this mechanism, and that using a limited simple mechanism is the only hope for retaining analysis of the static and dynamic net properties."

Chemists carried out these tasks using one of three systems: (a) the printed journals supplemented with a widely used printed index system, (b) a hypertext system (the SuperBook@ document browser), or (c) a new electronic system (Pixlook) that incorporates traditional document retrieval methods plus full text indexing and delivers bitmap images of journal pages.

It is a practice that has become increasingly common with the advent of “at your fingertips” information resources, To explore the characteristics of information triage and its interaction with spatial hypertext, a medium we claim supports the process, we have studied subjects engaged in a time-constrained decision-making task using a large set of relevant documents. We use the study task to investigate information triage under three different conditions: one in which the participants used paper documents, and two others in which the participants used variants of VIKI, a spatial hypertext system. Our findings suggest that during information triage attentional resources are devoted to evaluating materials and organizing them, so they can be read and reread as they return to mind. Accordingly, hypertext tools to support the practice should facilitate the rapid assimilation and assessment of new material, aid in the creation and management of a fluid category structure, allow readers to track their own progress through the information, and use minimum-effort methods to promote the intelligibility of results."

The popularity of the Web along with problems inherent in its design has motivated OHS researchers to integrate their systems with it. This research has primarily focused on enhancing the functionality of the Web via the services of an OHS. This paper presents three experiments exploring the integration of the Chimera OHS with the Web. While one of the experiments indeed describes work which enhances the Web, the other two investigate ways in which the Web can beneficially enhance an OHS. The paper concludes with a call for both communities to continue research which focuses on integration."

This approach, called Generalised Similarity Analysis (GSA), provides a unifying framework for extracting structural patterns from a range of proximity data concerning three fundamental relationships in hypertext, namely, hypertext linkage, content similarity and browsing patterns. GSA emphasizes the integral role of users’ interests in dynamically structuring the underlying information space. Pathfinder networks are used as a natural vehicle for structuring and visualizing the rich structure of an information space by highlighting salient relationships in proximity data. In this paper, we use the GSA framework in the study of hypertext documents automatically retrieved over the Internet, including a number of departmental WWW sites and conference proceedings on the WWW. We show that GSA has several distinct features for structuring and visualizing hypertext information spaces. GSA provides some generic tools for developing adaptive user interfaces to hypertext systems. Link structures derived by GSA can be used together with dynamic linking mechanisms to produce a number of hypertext versions of a common information space."

The popularity of the World Wide Web and its inherent vastness has only made things worse: many of the tools that were proposed to alleviate this problem in closed systems do not scale well when applied to WWW. We designed a tool, that we call The Aleph, that addresses the support of user navigation with two views, known as the Travel Map and the Content View. The Travel Map assists the user at the stage of traveling trough the docuverse, and the Content View helps him at the moment of recalling and organizing the known space. We developed a novel approach based on document collections, that takes advantage of 3D space, to give much more information than is usually available in 2D representations, and to simplify the map layouts. The maps provide a framework that relates document and terms with specific positions in space. The structure of the paper is as follows: Section 1 positions The Aleph in the context of a large-scale hypertext system as WWW. Section 2 shows the structure of The Aleph, the two views it provides, explains why to use different views, how they are related, and how they work. Finally Section 3 relates The Aleph to other tools that address similar user needs and design objectives."

In this talk, I will look back briefly at the first Hypertext conference (Hypertext ’87) and at the ten years of research and experience with the technology that have followed. However, most of the talk will be concerned with issues raised by the World Wide Web for this community.####Many members view the Web as an intrusive, unwelcome guest who insists on making his or her point of view prevail. Ignoring the hard-won knowledge of this community, the WWW has simplified the data model, ignored problems of large-scale navigation, and declared that link integrity is irrelevant. Consequently, many wish that it would go away so that they could continue their studies along familiar paths. Since it hasn’t, they have begun to adapt their work to it, but often grudgingly and with the least accommodation possible.####I will suggest a different perspective. The WWW, along with Java and the Internet, are not just new elements in the computing infrastructure. They are the infrastructure. Most computing and communication activities in the future will take place in this context. If the Hypertext community wants to continue and to create value for its knowledge, it must embrace the WWW, not just tolerate it.####What an exciting challenge! Consider how much richer and better the Web (or its successor) would be if it could incorporate features found in smaller, experimental system (such as integrated authorship, global write access, and reliable hyperlinks). But to do so at the scale implied by the Web will require substantial new work. The Hypertext community is uniquely positioned to contribute to that work, if it elects to move in that direction. To encourage this, I will outline some of the opportunities as well as challenges posed by the Web, and suggest several issues that might be included in a future research agenda for the Hypertext community.####[no references]"

Readers use a pen computer to annotate page images with free-form ink, much as they would on paper, and the computer constructs hypertext links based on the ink marks. This paper proposes two kinds of reader-directed links: automatic and manual. Automatic links are created in response to readers’ annotations. The system extracts the text near free-form ink marks, uses these terms to construct queries, executes queries against a collection of documents, and unobtrusively displays links to related documents in the margin or as “further reading lists.” We also present a design for manual (ad hoc) linking: circling an ink symbol generates a multi-way link to other instances of the same symbol."

The technique uses perceptually-based animation to provide a natural and lightweight feeling to readers.

Browsing and querying become natural, inherent, and compatible activities within the same semantic space. The overall design principle is based on the theory of cognitive maps. Techniques such as latent semantic indexing, Pathfinder network scaling, and virtual reality modelling are used in harmony. The value of this integrated approach is discussed based on initial results of a recent empirical study, which suggests that the spatial metaphor is intuitive and particularly useful when dealing with implicit information structures, or when a highly flexible and extensible virtual environment is required. Search strategies in association with the spatial hypertext and further work are also discussed."

An activity-based perspective is a view of the subspace of the WWW document space that a knowledge worker should understand or modify while executing the activity. We designed the framework to reduce the cognitive overhead of managing document spaces dependent on various internal and external changes. Changes within the activity (often resulting from the natural progress of the activity) result in changes of focus in the subspace related to the activity. For such internal changes, we introduce a temporally-threaded workspace model. Our model introduces a structured workspace that maintains a thread of snapshots of a knowledge worker’s perspective on a document space. Such threads of snapshots are constructed by monitoring user actions. External changes (for example, changes to documents managed in external sites) are independent of the progress of users’ activities. To deal with these changes, we introduce a proxy mechanism to maintain documents in the same state as accessed. This paper also describes the implementation of prototype systems, in the WWW environment, based on our frameworks. Interlocus is a client/server system providing facilities based on the temporally-threaded workspace model. It provides a user interface that presents spatial-temporal views of a workspace thread. Packrat is a WWW proxy server that maintains documents in the same state as accessed."

Michael Joyce, Cathy Marshall, Mark Bernstein, Carolyn Guyer, George Landow, Stuart research in traversal technology, and in their own Moulthrop and many others have explored the way in which metaphors of visual space can inform hypertexts—impacting both meaning and process. Although these writers refer to the time/space continuum, their writing has been less concerned with temporal constructs—how time might influence the programming, writing, and reading of hypertext literature. Time factors, however, could be viewed as important elements in the way hypertexts are conceived and received. This paper seeks to raise questions about issues of time—and to suggest some possible categories that might be investigated. Significant “information” is coded into everything from the equipment-determined limitations of “Machine Time” to the author-controlled clues embedded in “Mythic Time.” To the extent that we make mental scripts of spatial parameters, readers and writers of hypertext fiction may build into the space of the cyberworld a complementary universe fully as rich in temporal experience. In both the Interface Experience and the Cognitive Structure, time is part of the inscription of coherent meaning for cyber-narratives and electronic poetry."

Hypertext algorithms normally have a clear identity; for generalized cybertext, identity of the algorithm may need to be hidden. The algorithm might only be revealed by sampling activities; these activities might or might not be structured. Identity of the programmer needs to be considered as much as that of reader or writer. Hypertext is typically structurally focused; generalized algorithms exhibit behavior, and a behavioral rather than a structural focus may be important in certain types of cybertext. Hypertextuality is not “all or nothing”; there are dimensionalities to hypertextuality, only some of which may be present. The extensibility architecture should be flexible enough to allow for all of these dimensionalities."

To extract, meaningful structure under such circumstances, we develop a notion of hyperlinked communities on the www through an analysis of the link topology. By invoking a simple, mathematically clean method for defining and exposing the structure of these communities, we are able to derive a number of themes: The communities can be viewed as containing a core of central, “authoritative” pages linked together by “hub pages” ; and they exhibit a natural type of hierarchical topic generalization that can be inferred directly from the pattern of linkage. Our investigation shows that although the process by which users of the Web create pages and links is very difficult to understand at a “local” level, it results in a much greater degree of orderly high-level structure than has typically been assumed."

These observed needs have driven the development of new versions of Walden’s Paths.

According to Landauer, society fails to understand that information technologies breed complexity in almost every area of application; yet inexplicably we expect these technologies to deliver simplicity, efficiency, and a straightforward return on investment. Landauer answers these false expectations with “user-centered design” (UCD), asking us to shift attention from systems and software to people, their activities, and their needs. Though this is a promising thesis, it begs some primary questions: Who defines appropriate uses of information technology? How do new technological affordances affect our concepts of value and productivity? Could a more basic process precede UCD, one in which we redefine use itself? The talk applies these questions to the most notorious area of hypertext development, HTTP and the World Wide Web. What has the Web meant so far for business, academia, and society in general? Has widespread and relatively intense engagement with hypertext produced any changes in our understanding of this technology? What does it mean to LM the Web?####[no references]"

A major task in creating hypertext is link generation, and in particular for larger hypertexts, generating the links manually takes a lot of effort. Therefore, at least some support for link generation is highly desirable. We faced an important case of this problem in practice — to make explicit glossary links, i.e., links within and into a (technical) glossary. So, we developed a new and interactive algorithm for the semiautomatic generation of glossary links in hypertext. In order to be useful in practice, it deals with inexact matching of text and with names that may consist of several words, which may overlap or encompass each other in the text. Since the hypertext author using this algorithm should have full control over which links to include, our approach relies on user cooperation and interaction. Therefore, the design of our algorithm aims at reducing the cognitive overhead of the hypertext author. While we use this approach successfully in practice, its performance there is hard to evaluate quantitatively. So, we present a novel experiment design for quantitatively measuring the success of semiautomatic link generation and its application to our new algorithm. Both our qualitative empirical evidence and these quantitative results suggest its usefulness."

The system is based upon a modular architecture which allows the functionality of the system to be easily and dynamically extended. This paper describes the development of a distributed version of Microcosm based upon this modular design. The distributed system described utilises the fine granularity of the Microcosm model to support a wide range of wide possible configurations. The system also extends the document management facilities of Microcosm to allow information stored by other information services to be incorporated. The result is a system that can apply Microcosm’s open linking services to a wide range of networked information."

Based on a characterization of rich hypertext we introduce the concept of an interaction engine that governs the separation between internal hypertext representation and external screen presentation. This separation is the key principle of the HyperPro system. The HyperPro interaction engine is based on simple rules for presentation, interpretation of events, and menu set up. Much of the power of the interaction engine framework comes from the organization of these rules relative to the type of hierarchy of nodes and links, and relative to a hierarchy of so-called interaction schemes.

From our experience constructing hypermedia systems we have developeds an efficient process for this media-to-hypermedia transformation. By providing intelligent assistance. At each phase in the transformation the system can suggest likely nodes, key phrases, index values, anchors, and links to the editor. The project’s research focus is to identify the most effective methodologies to assist the human editor transform linear text, images and video into hypermedia structure."

A general solution is to extent hypertext systems to cater for semantics of application domains. This requires new hypertext models providing strongly typed documents and links. Such models have been proposed and put to use in systems such as HDM and MacWeb to facilitate authoring of large hypertexts. In addition, Gram and MORE use typing and graph-based hypertext schemas for querying hyperdocuments. In this paper, we will show how query languages could be further exploited for designing sophisticated general query-based navigation mechanisms. We illustrate our examples using the Gram model and describe an implementation with the hypermedia system Multicard connected to the object-oriented database management system O2."

A substantial body of work attempts to describe hypertexts in terms of extended or global spaces. According to this approach, nodes and links acquire meaning in relation to the space in which they are deployed. Some theory of space thus becomes essential for any advance in hypermedia design; but the type of space implied by electronic information systems, from hyperdocuments to “consensual hallucinations,” requires careful analysis. Familiar metaphors drawn from physics, architecture, and everyday experience have only limited descriptive or explanatory value for this type of space. As theorists of virtual reality point out, new information systems demand an internal rather than an external perspective. This shift demands a more sophisticated approach to hypermedia space, one that accounts both for stable design properties (architectonic space) and for unforseen outcomes, or what Winograd and Flores call “breakdowns.” Following Wexelblat in cyberspace theory and Dillon, McKnight, and Richardson in hypermedia theory, we call the domain of these outcomes semantic space. In two thought experiments, or brief exercises in interface design, we attempt to reconcile these divergent notions of space within the conceptual system of hypermedia."

It may be considered as applications research in support of the emerging information highways, that will enable the general public, SMES and other non-professional users to access facitilites that until now have been available almost exclusively to research workers and large corporations. The programme has been developed in close consultation with European industry; over 600 organisations have either attended meetings with the Commission or sent written comments on the draft documents. The aim of the consultation has been to create a programme that would provide support to application research activities that are of direct use to European industry.####The actions will use the results from programmed such as RACE and ESPRIT, that have created the individual building blocks but have not attempted to put them together into integrated applications. The scaling up of research results to industrial applications, ensuring that they interoperate successfully is a key step in moving from basic R&D to the marketplace.####The focus of the work will be on large pilot applications that integrate the different elements in the information chain: creating information, delivering it to users, and helping them to use it effectively. The new communications systems that deliver still pictures and video over the telephone network, require the tools for creating and managing information to be used in new ways. The design of information products must change to exploit the new technologies, so as to offer the public, particularly those who are not familiar with computers, products that are easier to use. New methods of presentation and filtering can reduce the growing information overload.

Reuse may be applied to items of different sizes and different complexity (from an elementary value to a large structured portion of the application). It may involve several aspects of the hypermedia application (content, organisation, presentation and connections). It can be implemented with different techniques, by creating a new copy of an item, or by sharing the same item in two (or more) different contexts.####In this paper we analyse hypermedia reuse under these different viewpoints, discuss a classification of different types of reuse, and present a few examples from commercial and prototype hypermedia titles.

The overall effect is the possibility to navigate the Web using spatial navigational metaphors. Textual virtual environments support the creation of diverse navigation tools and metaphors. The Juggler-system we describe can thus serve as an experimental tool to explore diverse navigational metaphors for the WWW. The system uses references to Web pages which can be arranged in any possible way and allows users to overlay a new secondary structure on existing Web structures, even using Web pages not on one’s own Web server. Textual virtual environments further support almost real time communication and interaction between several users. Because of the extensive interaction possibilities, the Juggler system can be used to discuss material on the Web, conduct guided tours through the Web or give presentations using material available on the Web."

Our content-link clustering algorithm is based on the semantic information embedded in hyperlink structures and document contents. HyPursuit admits multiple, coexisting cluster hierarchies based on different principles for grouping documents, such as the Library of Congress catalog scheme and automatically created hypertext clusters.####HyPursuit’s abstraction functions summarize cluster contents to support scalable query processing. The abstraction functions satisfy system resource limitations with controlled information 10SS. The result of query processing operations on a cluster summary approximates the result of performing the operations on the entire information space. We constructed a prototype system comprising 100 leaf World-Wide Web sites and a hierarchy of 42 servers that route queries to the leaf sites. Experience with our system suggests that abstraction functions based on hypertext clustering can be used to construct meaningful and scalable cluster hierarchies. We are also encouraged by preliminary results on clustering based on both document contents and hyperlink structures."

Although these models address crucial version support problems in specific hypertext application domains, they cannot be easily adapted and then integrated into other hypertext applications.####Hypertext version support environments have been introduced to help alleviate these problems. They are designed to meet the version support needs of a wide range of hypertext applications. However, so far few high level versioning facilities have been constructed in these environments, creating a gap between the facilities provided directly within the environment and the versioning needs of some applications.####The intent of this research is to bridge this gap. It turned out that task-based versioning styles are easy to use by both hypertext application developers and hypertext application users, As shown in previous work, task-based versioning helps to alleviate cognitive overhead and disorientation problems for users. In addition, it requires little investment from the point of view of application development, since task-based versioning does not necessarily require an application to incorporate an extra notion for individual versions. This paper presents a set of task-based hypertext versioning styles that are offered in the VerSE flexible version support environment and shows the direction towards the design of additional versioning styles."

The system creates queries from the users’ input and determines links dynamically based on matching between this query and indices.

However, recent advances in computer technology have enabled the development of new forms of text that violate standard assumptions of what texts are like. These new forms may pose serious problems for learning because they lack discourse features that readers rely on for assimilating new information. In particular, readers traditionally rely on the writer to determine the sequence of topics and to employ conventional cues that signal relationships among topics, such as relative importance or chronology. However, on-line hypertext systems present texts non-linearly, requiring readers to decide what information to read and in what order. This paper assesses the potential impact of non-linear texts on theories of discourse and on current cognitive theories of text processing. It also describes research in progress on readers’ sequencing strategies in hypertext. Research on the effect of hypertext on reading will have important practical implications for designing hypertext systems that satisfy readers’ needs."

We use the project to address two general problems arising with hypertext: the problems of controlling user/document interaction, and the problem of controlling the screen. We suggest that guiding users’ interaction with hypertext is difficult because of the unique form of discourse that hypertext represents, and that structuring user/document interaction can be achieved through specializing to a particular type of material and designing the hypertext system to respect the particular discourse structure characteristic of that material. EUCLID’s design is tuned to the structure of reasoned discourse. The problem of screen management in EUCLID is a serious one, because our presentation of complex arguments requires mapping the complex logical relations between parts of realistic arguments onto complex spatial relations between items in the display. We describe a general system we are developing which provides this high degree of control for hypertext screen management. This system represents a constraint-based approach to hypertext, in which the items from the underlying database that are to be displayed may each contribute a number of constraints on the layout; a general constraint-satisfier then computes a screen layout that simultaneously satisfies these constraints. Each time an item is to be added to or deleted from the screen, the constraint set is adjusted and the screen layout is recomputed; thus the spatial relationships on the screen provide at all times a veridical representation of the underlying relations between displayed database items. This kind of strong screen control is demanded by hypertext applications which, like ours, are fine grained: the number of nodes and links being displayed number in the hundreds."

Abstractions then become various first-order logic formulae. Specifically we consider abstractions: sets, sequences, aggregations, generalizations, revisions, and information structures. Interesting results of this work are the definition of level of generality of a hypertext node, the demonstration of revision histories as a partial order, and the notion of compatible-similar nodes.

An illustration of the concepts is given using the contexts mechanism suggested by Delisle and Schwartz [DS87]."

This paper discusses the DynamicDesign facilities that deal with the source code, sourceBrowser, and source tree builder utilities. GraphBuild is a utility used to convert C source code into a hypertext source graph, based on the program’s call tree. A data dictionary is constructed for the program that contains its local and global variables. The source browser allows the user to traverse, view, and edit a source code tree. Additional facilities for understanding and maintaining the source code and its auxiliary documentation are provided by the browser."

Hypertext systems are best suited for this purpose because of the diversity in information types that is permitted in the nodes of a hypertext. The integration of a hypertext system with software engineering tools results in a software hypertext system. We describe the design of such a system called DIF. Based on our experiences in using DIF, we recognized the need and the potential for developing a hypertext system that could utilize knowledge about its users and their software tasks and products. Such a system might then be able to act as an active participant in the software process, rather than being just a passive, albeit useful storage facility. As such, we define an Intelligent Software Hypertext System (I-SHYS1) as a software hypertext system which is knowledgeable about its environment and can use such knowledge to assist in the software process. This knowledge is partly embedded in the design of an I-SHYS (in terms of the ‘agents’ that I-SHYS supports) and partly defined during the use of I-SHYS (in terms of tasks that agents perform). We present a framework GOT defining and organizing this knowledge, describe potential uses of such knowledge, identify limits of our approach, and suggest methods for circumventing them."

Paths can also provide the backbone for computations over a hypertext, an important issue for the future of hypertext. This paper constructs a framework for understanding path mechanisms for hypertext and explores the basic issues surrounding them. Given this framework, it reviews path mechanisms that have been provided by other hypertext systems. Finally, it describes the Scripted Documents system, which has been developed to test the potential of one powerful path mechanism."

However, most of the recent hyper-activity in research labs and in the marketplace falls short of Bush’s vision. Most hypertext software is oriented toward hypertext as a new form of writing via incremental combination of bits and pieces of information. These hypertext programs typically provide little support for converting existing information from its more linear printed form, Where hypertexts have been created from existing text, they generally have been converted from a single encyclopedia ([Glus88], [Oren87]), a single reference document (D%isSS], [Per188], [Paym88]), or a single system’s documentation ([Egan89], [Walk88a]).

People who do not program, but who are computer literate and who want to go beyond the capabilities of word processing, spreadsheet and presentation software packages now use systems like Apple’sHyperCard, Owl’s Guide, Silicon Beach’s Supercard and Xerox’s Notecards not only to communicate, but to perform tasks that involve creating and integrating knowledge. This raises some important issues for designers of hypermedia systems. One of the largest is how to represent which pieces of information are linked (or hyper) and which pieces aren’t, within a given system or task domain. This, in turn, raises the issue of standards. Should representations of hyperness be consistent across systems and work domains, or should there be individual standards for representing hyperness within systems and work domains? The advantage of a standard is that it may assist users in discovering or labeling what is or isn’t hyper across a wide variety of systems. The disadvantage is that a standard severely limits the opportunities for creating systems that are closely connected to the content of specific areas of work, work environments and work tools. Thus, the apparent choice is between adopting a rigid hypermedia cuing standard, or redesigning hypermedia cues for each application."

Because hypertext systems are generally intended for developing informal (unstructured data) and semi-formal (semantic networks) structures, developing more formal structures can be difficult. Regular patterns in structures must often be recreated from primitive elements (individual nodes and links) resulting in a high overhead cost. In this paper we describe the Instructional Design Environment, or IDE, a hypertext system application that facilitates the rapid and accurate creation of regular network patterns in hypertext. IDE focuses on the task of instructional design, but its facilities are general and useful to many representation tasks. IDE features structure accelerators that provide simple menu interfaces to (1) define network structures out of patterns of typed node and link connections, (2) create new node types that contain structured content, and (3) tailor the interface for creating cards, links and structures to focus attention during different stages of the representation task. These mechanisms allow the user to tailor the hypertext environment to better meet his or her representational needs. We also report on the field use of IDE by instructional designers."

JANUS allows designers to construct artifacts in the domain of architectural design and at the same time to be informed about principles of design and the reasoning underlying them. This process integrates two design activities: construction and argumentation. Construction is supported by a knowledge-based graphical design environment and argumentation is supported by a hypertext system. Our empirical evaluations of JANUS and its predecessors has shown that integrated support for construction and argumentation is necessary for full support of design."

However, many did not receive sustained use due to issues of cognitive overheads and representational inflexibility. Many decided that such tools would never fulfill their promise.

For authors finding a good compromise between offering navigational freedom and offering guidance is difficult, especially in applications that target a broad audience. Adaptive hypermedia (AH) offers (automatically generated) personalized content and navigation support, so the choice between freedom and guidance can be made on an individual basis. Many adaptive hypermedia systems (AHS) are tightly integrated with one specific application. In this paper we study design issues for general-purpose adaptive hypermedia systems, built according to an application-independent architecture. We use the Dexter-based AHAM reference model for adaptive hypermedia [7] to describe the functionality of such systems at the conceptual level. We concentrate on the architecture and behavior of a general-purpose adaptive engine. Such an engine performs adaptation and updates the user model according to a set of adaptation rules specified in an adaptation model. In our study of the behavior of such a system we concentrate on the issues of termination and confluence, which are important to detect potential problems in an adaptive hypermedia application. We draw parallels with static rule analysis in active database systems [1,2]. By using common properties of AIIS we are able to obtain more precise (less conservative) results for AHS than for active databases in general, especially for the problem of termination."

We validate this by re-expressing established cinematic patterns, and relations relevant to scholarly hypertext, in terms of CCR, and with this conceptual bridge in place, present examples to show how cinematic techniques could assist the presentation of scholarly discourse.

Tools to help in this maintenance require an understanding of what changes are important, such as when pages no longer exist, and what changes are not, such as when a visit counter changes. We performed a study to look at the effect of the type and quantity of change on people’s perception of its importance. Subjects were presented pairs of Web pages with changes to either content (e.g., text), structure (e.g., links), or presentation (e.g., colors, layout). While changes in content were the most closely connected to subjects perceptions of the overall change to a page, subjects indicated a strong desire to be notified of structural changes.

Coupled with dynamic document generation, this allows complicated queries to be made without the user having to interact directly with the ontologies.####Our key contribution is a notion of hypermedia links between concepts and queries within an ontological information space. This approach is demonstrated with a Dynamic CV application built around the SoFAR agent framework and the Fundamental Open Hypermedia Model (FOHM). In addition to abstracting the interface, Open Hypermedia allows alternative linkbases to be used to represent different “query recipes”, providing different views and navigational experiences to the user."

As a result, it is even more difficult to identify when documents are related.

This paper presents an infrastructure allowing the use of latent semantic analysis and open hypermedia concepts in the automatic identification of relationships among web pages. Latent Semantic Analysis has been proposed by the information retrieval community as an attempt to organize automatically text objects into a semantic structure appropriate for matching. In open hypermedia systems, links are managed and stored in a special database, a linkbase, which allows the addition of hypermedia functionality to a document without changing the original structure and format of the document. We first present two complementary link-related efforts: an extensible latent semantic indexing service and an open linkbase service. Leveraging off those efforts, we present an infrastructure that identifying latent semantic links within web repositories and makes them available in an open linkbase. To demonstrate by example the utility of our open infrastructure, we built an application presenting a directory of semantic links extracted from web sites."

Yet computer science seems to me wrongly centered around two traditional, conventional constructs: the simulation of hierarchy and the simulation of paper. It is a popular myth that “structure” means hierarchy; and it is a popular conception that electronic documents should simulate paper. These two concepts have the additional advantage of being easy to explain to beginners. Accordingly, since the nineteen-forties we have simulated hierarchies to organize computer files, and since the nineteen-sixties we have progressively simulated paper—from “text editing” to “word processing” to “desktop publishing” to the Web (which added one-way links to simulated sheets of paper). Now, merging hierarchy simulation with paper simulation, we have been given Adobe Acrobat (simultaneously simulating hierarchy and paper side by side) and XML (a system for transforming paper simulation into hierarchy and vice versa). I see these as ideological exercises in completing the hierarchy and paper paradigms, bypassing the vital issues. Rather than imitating the shortcomings of the real world, we should be correcting the insufficiencies of hierarchy and the deficiencies of paper. Things being simple-minded and easy to explain does not make them sensible or right.####[no references]"

It argues that these practices limit the development of hypertext rhetoric by privileging a discrete or granular model of discourse nodes as stable units connected by purely transitional links. The paper explores the limits of the node/link model, suggesting that links can take on certain properties of nodes and vice versa. Drawing on the phenomenological critique of rationalist mechanism developed by Winograd and Flores, the paper presents an alternative discourse model for hypertext which regards nodes and links in complementarily, as contingent structures subject to conceptual “breakdown.” Applying this model to actual communication practices, the paper invokes Zuboff’s distinction between “automating” and “informating” applications of technology, outlining a rhetoric based on a constantly evolving textual structure  in which object relations remain fluid. A new term is proposed, the informand, to designate the communal interactive discursive space created by informating systems like hypertexts and artificial realities. The paper concludes by urging experimentation with informating practices in hypertext, a move away from print models and towards all-electronic composition."

Until now, the fisheye-view strategy, introduced by Fumas, is only applicable in structures where the necessary components of the fisheye-view function can be defined. Unfortunately, directed graphs are structures where the fisheye-view function of Furnas cannot be applied. Therefore the fisheye-view concept was of limited value in hyperdocuments represented by such graphs. To overcome this lack, this paper proposes an enhancement of Furnas’ function to allow its application in hyperdocuments of that kind.####We will begin with a short review of Furnas’ well-known fisheye-view concept. Thereafter, we will discuss the problems that arise when one attempts to apply the concept in so-called ,,unstructured” hyperdocuments. The results of this discussion lead to the development of a function which satisfies the requirements of the concept, and allows its use in hyperdocuments of almost any structure. To show that the fisheye-view concept of Fumas remains fulfilled, an appropriate theorem is formulated. The result is that the benefits of the fisheye-view concept can now be appreciated in ,,unstructured” hyperdocuments. In closing, we offer a detailed example, which illustrates the behavior of the enhanced fisheye-view function."

But current systems still have some unpleasant restrictions. For example, only few hypermedia systems support the design of higher level hypermedia objects beyond the basic node-link paradigm. There are further restrictions concerning the modularization of the overall design and the reuse of (complex) hypermedia resources. HYDESIGN is the prototype of an extensible hypertext/ hypermedia system which addresses these restrictions. The crucial part of the development is the data management component, the HYDESIGN-engine, which has been built on top of the Gem Stone object-oriented database management system. A first prototype of a graphical user interface, the HYDE SIGN-GUI, has been developed in Smalltalk-80.####This paper focuses on central features of the HYDESIGN data model representing the conceptual basis of the HYDESIGN-engine. Aggregate links of differefit types are introduced which allow for the creation of higher level hypermedia networks. SBL-nodes represent particular composite nodes offering the capability of defining (nested) local environments with particular behaviour. Also different options for the sharing of hypermedia resources are proposed. HYDESIGN further supports navigation as well as query based access in an integrated approach. As a whole, HYDESIGN aims at a better support for the hypermedia design process by the provision of powerful structuring facilities."

For example, if a reader browses to a node that has no out links, then backing up, or “warping” to the table of contents can allow the browsing session to continue.####If hyperdocuments are to become interchangeable among hypertext systems, rather than being readable only on the systems from which they are authored, one obvious but complex approach is to try and standardize on (most likely, very many) browsing features and behaviors, forming some standard union of the capabilities of current major implementations. This approach molds (or perhaps restricts) future systems, since new browsing “features” must then be worked into such a standard. An alternate approach, used in this paper, is to de-emphasized browser features and emphasize inherent document structure with browsing semantics. An author should be able to create document structure so that the desired meaningful access patterns are inherently allowed by links rather than by browser capabilities.####We present a method of analyzing the browsing properties of a hypertext document by examining the links alone. This method is not specific to any particular hypertext system or document authoring, format. With it, an author can be certain that a document will allow particular access patterns when read on any browser implementation that has a single navigation operation: direct link following. The method requires a mental shift in how a hyperdocument is conceived abstractly. Instead of treating the links of a document as defining a static directed graph, they are thought of as defining an abstract program, termed the links-automaton of the document. A branching temporal logic notation, termed HTL*, is introduced for specifying properties a document should exhibit during browsing. An automated program verification technique called model checking is then used to verify that these specifications are met by the behavior of the links-automaton. We illustrate the generality of our technique by applying it first to a Trellis document, and then to a Hyperties document."

In other systems, concern for the economics of manually linking large bodies of existing information, coupled with a desire to promote more responsive and reconfigurable interfaces, has spurred the development of automated tools, intensional or virtual structures, automatic node content generation and automatic link discovery.####Some claim that, apart from annotation features such as commenting, the significant hypermedia systems of the future will be entirely automated.####In this panel we explore the potential and dangers of automating hypermedia.####Hypermedia automation includes converting documents, mapping applications and navigating hypermedia networks.####Converting Documents####Different domains call for different types of conversion–traditional letters and reports, electronic mail messages, the messages and reports an expert system produces, etc. Conversion may be invoked by, e.g., importing a document, an electronic mail or EDI message arriving, or a user querying or requesting computation. Converting a single document can result in a single node linked to other nodes–with or without embedded link markers-or could extract an entire hypermedia (sub) network of nodes and links.####Mapping Application Domains####Automated mapping recognizes an appication domain’s implicit or encoded structure and realizes this in terms of a hypermedia data model. The structure of the resulting hypermedia representation will depend upon its intended use-to guide navigation, to serve as a user interface to a complex application, or to reveal a new way of organizing and interpreting a collection of materials. The hypermedia system also may use this structure to generate composite objects and net work overviews automatically.####Navigating Hypermedia Networks####Automation may support the navigation of virtual structures, especially when a mapped hypermedia network dynamically portrays the currently active portion of an external application or data base. Here the hypermedia system often must resolve (and perhaps compute) link destinations on demand. The hypermedia network can be generated (or tailored) as the result of a query or choosing an application command, e.g., within a CAI system.####Automated generation often is touted as an attractive means of maintaining the consistency of the “knowledge” a domain represents. Yet automation incurs the risk of incorrectly identifying and omitting links, thus impoverishing the information they relate.####When converting a document intended by its author to convey a particular effect, hand-crafting is often called for to fit the message to the medium and to avoid misleading links. Thus, despite promising developments in link discovery, automatic hypertext conversion and interactive network generation, critics still question whether the quality of automatically-generated nodes and links can approach those produced by hand-crafted methods, and in some cases, whether automatic methods are mandated economically.####In this panel we shall discuss the visions, prospects and potential for automating hypermedia in the next millennium. Issues include:####● Where is hypermedia automation heading?####● Is there a central essence of hand-crafted hypermedia that automation fails to capture?####● Is automatic conversion of linear documents an economic necessity? A transitional technology? A futile exercise?####● Are the constraints purely technical or are we still awaiting paradigms and frameworks to advance the concept of what can be automated?####● Do knowledge representations facilitate automation? Can explicit structure be harmful to a hypertext?####● Can we generate a hypermedia network solely from structure declarations? When is content unimportant to hypermedia generation?####[no references]"

The ability to mark surfaces in relatively stable ways has made it possible for people distributed across space and time to see the same images and thereby to have access to the same meanings or communicative intent. Today, however, with the increasing use of digital technologies, it is often asserted that we are moving from the fixed world of paper documents to the fluid world of digital documents. In this paper I challenge this assertion, arguing instead that all documents, regardless of medium, are fixed and fluid. Thus, although paper documents do fix aspects of communication, they do (and must) also change; and although digital documents are easily changeable, they must also be capable of remaining fixed. I make use of this analysis in two ways: first, to examine the fixity and fluidity of hypertext; and second, to critique Bolter’s argument in Writing Space concerning the movement from “fixed to fluid.”"

Querying in hypertext has been a requirement since [19] and has already been elaborated in many hypertext systems, but has not yet been used for hypertext systems superimposed on an underlying hierarchical logical structure. In this paper we use the model and the SQL-like query language of [10] in order to manage structured documents with hypertext links. The model represents a structured documents with hypertext links. The model represents a structured document with typed links as a complex object, and uses paths through the document structure, as first class citizens in formulating queries. Several examples of queries illustrate, from a practical point of view, the expressive power of the language to retrieve documents, even without exact knowledge of their structure in a simple and homogeneous fashion. It must be stressed that the proposed model and language implement the equivalent HyTime Location Address Module. In fact, the language is more powerful than the corresponding HyQ query facilities. The implementation and the description throughout the paper use the SGML standard to represent the document structure and the object-oriented DBMS O2 to implement the query language and the storage module."

Content-oriented integration provides an integrated navigational environment that consists of both conceptual-based navigation and media-based navigation. For the conceptual-based navigation, each media representation is translated into a conceptual representation with the help of media recognition techniques and media understanding techniques. The media representation derives its own semantics by connecting the media-independent part to the conceptual representation such as an object name, keywords, etc. Media-based navigation supports media-dependent information difficult to translate into the conceptual representation. Conceptual-based navigation and media-based navigation enrich navigational capabilities in complementary fashion.####We also describe our content-oriented integrated hypermedia system “Himotoki”. It provides a wide variety of navigational tools such as visual content-based navigation, moving hot-spot navigation and schema navigation. Each media translation is modularized as the corresponding media augmenter so that it can flexibly adapt to a distributed environment. Applications such as “Electronic Aquatic Life” and “Hypermedia Museum” demonstrate the usefulness of these navigational tools."

This paper describes a third view of hypermedia — hypermedia as a computing paradigm. In this paper, we explore the implications of pushing hypermedia beyond its traditional role in human-computer interaction and information organization into the computer’s core operating environment. We believe the resulting hypermedia operating systems provide a new paradigm for computing — one in which human-computer interaction, information storage and retrieval, programming, and control are integrated in a common conceptual framework. We discuss the basic concepts of hypermedia operating systems and describe a general hypermedia operating system architecture and prototype.

The paper discusses some of the possibilities that automatic traversal of relationships in the index space holds for hybrid query/navigation tools, such as navigation via similarity and query generalisation. The example scenario suggests that, although these tools are implemented by complex queries, they fit into a browsing, rather than an analytical style of access. Such hybrid navigation tools are capable of overcoming some of the limitations of manual browsing and contributing to a smooth transition between browsing and query. A prototype implementation of the architecture is described, along with details of a social history application with three dimensions of classification schema in the index space.

Because analytical applications generate their screen contents in real time, hypertext constructs and navigation paths must be generated and mapped in real time. We are developing a hypertext engine that provides dynamic mapping automatically for any analytical application. W e propose a standard, generic open hypertext system (OHS) wrapper for back-end or storage-level components that dynamically generate their contents (e.g., the analytical applications). The wrapper automatically maps hypertext constructs-nodes, links and anchors—to application contents, (The storage-level wrapper itself creates hypertext constructs instead of the users.) The hypertext engine delivers supplemental hypertext functionality based on these mappings. Furthermore, by providing a standard format and a set of guidelines, we are providing a standard protocol or systematic approach for exchanging information between an OHS and any analytical application. This adds to the work in the OHS community on developing a standard protocol users will employ them for their primary analytical functionality. Hypertext will give more direct access to this primary functionality, give access to metainformation about objects that appear on the application screen, provide alternate navigation paths through the application space, and enable annotation and ad hoc links. Because these analytical applications generate their screen contents in real time (as opposed to just retrieving existing documents and display contents), hypertext constructs and navigation paths must be generated and mapped for these screens in real time. Our research goal is to provide a hypertext engine that can handle this real-time or dynamic mapping automatically for any analytical application. (We call these applications dynamic-mapping information systems or DMISS.) Furthermore, as we cannot expect to change these applications in any major way, we need to leave them “hypertext-unaware”. The hypertext engine will perform all hypertext functions, and maintain all hypertext mappings and constructs on their behalf. Indeed, for applications with APIs where we can provide our own user interface, we need make no changes to the application at all, while providing with complete hypertext functionality.####We propose a standard, generic open hypertext system (OHS) wrapper for back-end or storage-level components (DMISS) that dynamically generate their contents.

In other words, from the OHS viewpoint, the storage-level wrapper itself creates many of the nodes, links and anchors instead of the users at the user interface level.

Needless to say, it is difficult and dangerous to predict what the future holds for Hypertext although it is the province of the closing keynote to do so. Since driving is an activity that requires one to look into the future (if only the most immediate future), I will apply the 5 principles of the Smith System of Defensive Driving to our field to chart a provident course for practising “safer hypertext.” These principles, coupled with observations of our emerging practices and our current wave of technologies (especially, and in particular, the Web), are surprisingly generative.####1. Aim high to steer accurately and anticipate problems. We are beginning to have some experience with navigation on a large scale. Will increasingly sophisticated search engines, filters, and agents obviate the need for links (especially hand-constructed links)? I will explore the growing tension between the order created by links and the order implicit in nodes.####2. Keep your eyes moving—avoid a fixed stare and stay alert. Is reading changing? As a field, we have grown increasingly sophisticated in our methods for designing hypertexts for comprehension, for accessibility, for ease-of-use”. By focusing on tools and methods for designers, we tend to overlook readers and what they are up to these days. What might a next generation of tools look like, given a reader-centric view of hypertext?####3. Get the big picture—don’t allow your eyes to be drawn to one area. Is the node-link traversal-based model still working for us? What assumptions about space, time, and atomicity are buried within? I will visit some contrarian models of hypertext.####4. Leave yourself an ‘out’—practice the “what if” game. When we enter the world of hypertext, we seem content to leave the corporeal world behind. Yet there is still life outside (and beside) our glowing CRTs. How can we expand open hypertext to reach beyond the limits of the virtual world?####5. Make sure the other drivers see you; make eye contact. The four other Smith System principles don’t completely acknowledge the social nature of the world. Rule 5 brings other drivers into the picture. By contrast, we have long recognised co-operation as an important force in hypertext. What shape is this co-operation actually taking, given the Web and other communications technologies?####[no references]"

But this conventional model may not be appropriate for collaborative hypermedia systems, where the multiple users work together in groups on shared tasks.####Further, it is desirable to construct collaborative hypermedia systems on top of the World Wide Web, but most web servers do not support even conventional transactions, let alone distributed (multi-website) transactions or flexible concurrency control mechanisms oriented towards teamwork—such as event notification, shared locks and fine granularity locks.####We present a transaction server that operates independently of web servers or the hypermedia applications, to fill the concurrency control gap. The transaction server by default enforces the conventional transaction model, where sets of operations are performed in an all-or-nothing fashion and isolated from concurrent users. The server can be tailored dynamically to apply more sophisticated concurrency control policies appropriate for collaboration. The transaction server also supports applications employing information resources other than web servers, such as legacy databases, CORBA objects, and other hypermedia systems."

This ensures that the desired spatial, temporal and navigation properties are maintained no matter how the presentation is adapted to varying circumstances.####Rhetorical structure defines author intent at a still higher level. Authoring at this level requires that rhetorics can be translated to final presentations that properly reflect them.

It can be used first as an informal mechanism to describe the attributes of objects and to capture relationships between the objects. Then hypertext structures can be constrained into a more formal representation of a domain, model, or analytic technique. A range of strategies for using hypertext can be employed to describe a problem and converge on an appropriate representation; competing representations can be informally evaluated to compare their relative expressive power. This paper discusses several applications that have used NoteCards, a hypertext idea processing system, to tackle representation problems. Examples from each problem domain have been collected using the hypertext system as the initial acquisition vehicle. Subsequent analysis using hypertext structuring tools has revealed the semantics of each problem domain enabling the development of competing representations. Abstraction of the structure and form of these representations can be used to guide system extensions. These tailored extensions support the evaluation of a representation’s relative merits; the representation that has been developed in response to a particular problem can be applied to analogous problems to determine the limits of its scope. The first application described in this paper models a type of policy decision-making process; the second looks at approaches to representing the logical structure of an argument; and the third suggests some methods for capturing the structure of a political organization as an alternative to a conventional database design. The applications are discussed in terms of the issues they raise and the trade-offs they involve, how hypertext-based tools have been used to exploit the representations, and the solutions and techniques that have been developed in the process of creating each representation."

These retrieval models specify strategies for evaluating documents with respect to a given query, typically resulting in a ranked output. Hypertext researchers, on the other hand, have emphasized flexible organizations of multimedia “nodes” through connections made with user-specified links, and interfaces that facilitate browsing in this network of links. A number of approaches to the integration of query-based retrieval strategies and browsing in hypertext networks have been proposed. The 13R system [Crof87,Thom89] and a medical handbook system described by Frisse [Fris88], for example, use query-based retrieval strategies to form a ranked list of candidate “starting points” for hypertext browsing. The 13R system also uses feedback during browsing to modify the initial query and locate additional starting points. The important issue from an IR perspective is the choice of a retrieval model, and consequently a retrieval strategy, for hypertext. This choice will have an impact on the effectiveness of retrieval and on the system implementation. A retrieval model can also provide a more formal specification of the meaning of some hypertext links."

Adequacy and cost effectiveness are perhaps the most obvious from the producer’s perspective additional criteria are important for users. Examination of the limitations of various assessment criteria highlights the twin issues of the cognitive costs and benefits experienced by people using hypertext as part of some other task. Many interface characteristics can contribute to readers’ cognitive overheads. There is evidence that even changing screens to access information only a click away can impair memory processes. Fortunately, because hypertext are computer-based, readers can call upon a variety of aids to support their cognitive activities, particularly memory and planning processes. The novelty of some of these prostheses raises questions about the literacy skills that hypertext readers may need. Studies of factors influencing readers’ strategic decisions about using memory aids are discussed, together with their implications for hypertext design. It is concluded that hypertext evaluation requires a richer understanding of the cognitive entailments of working with information. But hypertext, having highlighted the problems of cognitive costs, have the potential for offering readers the means of reducing these overheads not just for hypertext use but for many tasks that involve working with information."

Included are discussions of the selection process, why hypertext is well suited for supporting selection, and important characteristics of hypertext systems intended to support reuse. Also discussed are how reusable libraries can be structured using hypertext, how such libraries can be mechanically built, and how their use enhances the component selection process.####Kiosk consists of an open set of tools that can create, browse, and modify nodes and links in a software library. One of these tools, Cost++, can automatically generate a linked structure for libraries by clustering workproducts into components, and then placing components into multiple classification hierarchies. The Kiosk browsing tools allow users to peruse the components in libraries, examine library structures from multiple perspectives, and add new links and nodes to enhance the standard library structure."

One reason for the complexity of hypertext databases is the large number of nodes and links that compose them. To simplify this structure we propose that nodes and links be clustered forming more abstract structures. An abstraction is the concealment of all but relevant properties from an objector concept.####One type of abstraction is called an aggregate. An aggregate is a set of distinct concepts that taken together form a more abstract concept. For example, two legs, a trunk, two arms and a head can be aggregate together in a single higher level object called a “body.” In this paper we will study the hypertext structure, i.e., the way nodes are linked to each other in order to find aggregates in hypertext databases. Two graph theoretical algorithms will be used: biconnected components and strongly connected components."

One of the main problems in using hypertext systems is the navigation problem [Ni90a]. Users tend to get lost partly because the information they are reading can have a complicated structure which is usually unknown to them. We study in this paper a technique to help users orient themselves by a quick browsing, which we call flying, through hypertext.####The first thing many people do when given a new book is flip through the pages to get a first impression of the book. Quite a bit of information can be gained by this quick informal evaluation. First, just the size of the book is a good indicator. A ten-page brochure is treated differently than a 500-page instruction manual. The book’s density (how many characters per page), its layout (e.g., the font, the percentage of pictures), the technical content (e.g., number of equations, number of technical drawings), familiar features (e.g., pictures or drawings that the reader has seen elsewhere), just to name a few simple things that can be determined quickly, all give us important information about the book without reading even one sentence. This kind of information is not immediately available in hypertext, and we believe that the lack of it contributes to the navigation problem. We would like to provide this type of information in a quick and flexible way.####We describe in this paper a tool for flying through hypertext systems and discuss the issues involved in its implementation. Our tool is analogous to flipping the pages of a book with one notable exception: the flipping is not necessarily in a linear order. The availability of the links and the structure that they provide enable flexible flipping in many different orders controlled by the reader. The key to any flipping is speed. The goal is not to digest the contents of the pages, but rather to gain some insight to features such as organization, size, depth, level, detail, and so on. Another analogy is to seeing a movie, or better yet a videodisk, in fast forward. There are certain characteristics of the movie that can be studied better that way. Flying can also be used to move fast from one place to another in the hypertext following a certain order of traversal. Flying is not intended to replace any of the other navigation tools; it is an additional tool."

If he wants to ensure that his readers understand the entire hyperdocument as a coherent entity, he needs means to indicate its structure in a comprehensible way. In this paper, we propose a construction kit which provides dedicated design objects for this purpose. The design objects can be characterized as building blocks for three functionally different components of a hyperdocument: its content part, organizational part, and presentation part.

This paper illustrates the need for alternative models by exhibiting a particular reasoning task for which navigating among nodes by way of explicit links is less effective than an alternative model of intersecting sets of nodes. The task is taxonomic reasoning, a particular kind of reasoning task that deals with the comparison and classification of highly similar nodes, in which an analyst viewing one node thinks not in terms of linking it to another node, but of including it in or excluding it from a set of related nodes.####This paper discusses this kind of reasoning and describes HyperSet, a set-based hypermedia system designed to support it. It compares HyperSet with other tools that support taxonomic reasoning, discusses the formal and implementational relationships between graph-based and set-based hypermedia, and defines the features that are required in a hybrid system that can concurrently support both set and graph manipulations."

Some of these writers (notably Carlson, Jaynes, and Landow) explicitly invoke the subject of rhetoric; others address issues of structure and convention in electronic composition that clearly pertain to this subject. All have considered ways in which hypertext can be used or made more useful in actual writing situations. But in spite of the considerable attention given to this area of inquiry, the nature and objectives of hypertext rhetoric are still vaguely defined.####What exactly is meant by “the rhetoric of hypertext?” The term rhetoric allows widely various definitions—from the classical sense of a specialized art of political oratory (Kinn82) to the more modem idea of a comprehensive study of communication events across multiple social domains (Haus86). In regard to changes in media, writers are most likely to place themselves somewhere between these two polarities, working toward a rhetoric which is both normative and practical: oriented toward effective acts of communication but also concerned to define the social contexts by which effectiveness is judged."

The basic features of HDM are the representation of applications through several design primitives: typed entities composed of hierarchies of component different perspectives for each component units corresponding to component-perspective pairs; bodies representing the actual content of the units; structural links, binding together components or sub-entities of the same entity; typed application links, interconnecting components belonging to different entities; and a specific browsing semantics based on anchors, as a way to activate many different link types from within a unit.####The development of HDM is part of the HYTEA project, carried on by a European consortium, aiming at the development of a set of authoring tools for an “engineered” development of Hypertext-Hypermedia applications. A HYTEA application is made by an HDM schema and an HDM Hyperbase (i.e., a set of instances). The basic HDM has already been shown to be translatable, either manually or through a compiler, into a node-and-link model (“a la DEXTER model”); the translated application can be targeted on several implementation tools (i.e., standard Hypertext tools already available on the market). HDM has already been used to develop a (small number) of applications, and to describe preexisting applications. These experiments have shown the need for improvements that are discussed in the paper: aggregate entities; sharing of components; is-a relationships and inheritance between entity types; sharing of bodies; structured access and “guided tours”; use of active media (animations and video-clips)."

Unfortunately, in most hypertext systems, the weakness of structure specification mechanisms discourages the development and use of such a model since it is difficult to reinforce hypertext structure and to really incorporate knowledge. A lot of works provide intelligent mechanisms to help navigation but either they use external knowledge or automatically synthesize links from information included in nodes which thereby have no sufficient conceptual value.####The present paper focuses on an object-oriented hypertext model (implemented in the MacWeb system) using structured types to incorporate knowledge in hypertext. Concepts and their relationships as well as their instances and their own relationships may be represented. Such a model makes the capture of knowledge at source easier thus allowing a more conceptual navigation, Furthermore, active behaviors may be associated, as methods, to types. This provides a powerful mechanism to help develop structured hypertext as well as task centered applications, by taking advantage of knowledge representation."

Since many more such works are produced than can be read/seen/heard by any individual, users rely on reviewers to inform them of interesting new publications and performances. From an academic perspective, analyses and reviews of works of art are a major way of generating new insights into their respective spheres of human expression.####Since hypertext is seen by enthusiasts as a major new communications medium, it would seem reasonable to review and analyze efforts at writing and composing hypertext documents. It is difficult to discuss hypertext without reference to concrete hypertext documents. For example, [Nie190] used examples from about fifty different hypertext and hypermedia documents in discussing various aspects of hypertext. Even so, it is still fairly rare to see actual reviews of hypertext documents as communicative efforts in their own right and not just as examples of hypertext concepts. Some such reviews are starting to appear in the popular press, and research journals are also starting to carry in-depth reviews of hypertext to some extent (e.g., [Hard91]). Also, professors teaching hypertext courses have started to consider ways to grade hypertext documents authored by students [Brow90]."

Despite the fact that such hypertext technologies are now largely effective in operation we find that:####● hypertext technology suppliers have not, in general, found a ready and profitable market for their wares. Many suppliers have stumbled and several have failed.####● outside the limited area of arcane technical and procedural documentation it is still very difficult to identify a hypertext product which has experienced any substantial measure of success.####● non-hypertext solutions, such as Document Image Processing, and Full-Text Retrieval, continue to grow despite their lower effectiveness in many practical applications.####So what has gone wrong? Were we all over ambitious about the efficacy of interactive documentation? Are we still waiting for the “killer product” to kick-start the market? Can literature and electronic delivery ever mix; or will society look to the electronic device solely to deliver picture and voice? Will the public ever accept text from other than the printed page? The answer lies in a combination of circumstances:####● The existence of suitable infrastructure, including such factors as high bandwidth communications channels and effective marketing channels. If our existing channels are compared to, lets say, the transport systems of two hundred years ago, how long will it take us to build the equivalents of the canals, railways, highways, and air transportation systems that we will need? Who will provide them and what will be the commercial basis of their success? As we supply solutions which, due to technological inertia, are non-optimal; how long will it take us to recover from such cul-de-sacs?####● The successful new consumer electronic literature products must meet demonstrable mass-market needs. Public accept ante will be driven by the effectiveness of the product at delivering information in a way which is clearly superior to other methods. It will also be driven by factors such as style and fashion which are notoriously difficult to predict. The attitude of the public was also be damaged by highly visible failures - and there may be several on the way!####History has shown that technology companies have been poor at predicting such changes in social behaviour, and that when supplied their products often miss the real target. What kind of companies will actually solve these problems, and what circumstances will persuade them to make the investment?####● The elimination of the remaining technology and financial barriers (most pertinently the mass production of high quality, portable, low cost display devices). Although a preoccupation of the technologists this is probably the easiest of these barriers to resolve.####At some point these factors Will add up. When the effectiveness and transparency of the new publishing product are perceived as overcoming the change and cost required to obtain them )and, incidentally, the new product is blessed by the ‘style gurus’) the public will adopt it enthusiastically. The cellular telephone and the fax machine are such examples from 1980s. This presentation will consider the factors which will influence the adoption of electronic literature as a a mainstream product.

Audio elements are basically sequences of digitized audio samples, while visual elements are sequences of raster frames. In either case the sequences may not be stored explicitly, but instead stored in a compressed representation, or an alternate representation from which the sequences are produced (as when audio is synthesized from a symbolic representation, such as musical notation, or video frames are rendered from animation data).####Because of the temporal nature of digital video, its production and consumption often requires be stored and retrieved from conventional storage specialized devices capable of the real-time handling of streams of data. Until recently this equipment was expensive and not readily available. However a number of significant advances are now taking place that are greatly increasing the use of digital video. These developments include advances in high-bandwidth networks and protocols facilitating real-time transfer of digital video; improvements in storage media such as high-capacity magnetic disks and writable CDs; faster rendering rates for graphics hardware allowing real-time animation; greater availability of special-purpose audio and video processors on workstations; and better computer interfaces to both commercial and professional video products such as camcorders, VCRs, and video mixers. Another significant development is real-time compression and decompression hardware for digital video. The compressed video has data rates comparable to bus and disk bandwidths and so opens the possibility of video recording and playback from conventional secondary storage devices. In addition, an anticipated future development having broad-impact on the use of video, will be the emergence of standards for HDTV.####In light of these changes, new possibilities are arising for application developers - in particular those who aim to enhance hypertext, or hypermedia, with video capabilities. Early interactive video systems relied on analog read-only videodisc technology. This “first generation” of video-based hypermedia provided very good video quality, but suffered from limitations imposed by the videodisc. Now digital video offers a way around many of the drawbacks of the videodisc - digital video can be edited and modified, it can be processed, and, like any other form of data, it can be stored and retrieved from conventional storage systems.####This presentation will focus on implications of digital video for hypermedia. A short overview of video technology will be provided, introducing such topics as video formats, video compression, and video editing. Several low-cost platforms for running digital video applications will be described and illustrated with short videotapes.####Finally we consider a number of traditional hypertext issues in the context of digital video. Approaches to linking video with other information, techniques for structuring video and increasing interactivity during playback, and new forms of composition and navigation will be presented. Many of these techniques are now being explored in prototype systems. Examples of existing prototypes will be used to illustrate the potential of digital video when used in hypermedia systems.####[no references]"

In this research, we focus on separating the adaptation engineering process from regular Web engineering by applying aspect-oriented techniques. We show how semantic information and metadata associated with the content can be exploited in our aspect-oriented approach. Furthermore, the approach allows the use of global (structural) properties of the Web application in adaptation specification.

A key question in this new context is whether users search for media in the same way that they search for text. This paper presents a first step towards answering this question by providing novel analyses of people’s linking and search behavior using a leading video search engine. Initial results show that page views in the video context deviate from the typical power-law relationships seen on the Web. However, more positively, there are clear indications that tagging and textual descriptions play a key role in making some video-pages more popular than others. This shows that many techniques based on text analysis could apply in the video context."

Designing and working with large-scale participatory social computing applications requires that we think not just about technological issues, but also about fundamental principles of human social interaction. Through the digital traces that these applications generate, we can begin to quantify and reason about such principles at unprecedented levels of scale and resolution.####In this talk, we consider a crucial type of social process in this setting - the mechanisms by which information flows through groups of people engaged in sharing and synthesizing knowledge. As information, ideas, opinions, and beliefs spread through an underlying social network, their dynamics resemble that of an epidemic, moving “contagiously” from person to person. But social contagion is different from biological contagion in many respects; understanding the analogies and contrasts between these two kinds of processes leads us to consider the rich temporal characteristics of information flow within a network and the complex decision rules by which people choose to act on new information. The result is a richer picture of the communities that create knowledge and its interlinkages, and of the resources that ultimately arise from these processes.####[no references]"

This vast array of information presents unique opportunities to harvest knowledge about user activities and interests through the exploitation of large-scale, complex systems. Communal tagging sites, and their respective folksonomies, are one example of such a complex system, providing huge amounts of information about users, spanning multiple domains of interest. However, the current Web infrastructure provides no mechanism for users to consolidate and exploit this information since it is spread over many desperate and unconnected resources. In this paper we compare user tag-clouds from multiple folksonomies to: (a) show how they tend to overlap, regardless of the focus of the folksonomy (b) demonstrate how this comparison helps finding and aligning the user’s separate identities, and (c) show that cross-linking distributed user tag-clouds enriches users profiles. During this process, we find that significant user interests are often reflected in multiple Web2.0 profiles, even though they may operate over different domains. However, due to the free-form nature of tagging, some correlations are lost, a problem we address through the implementation and evaluation of a user tag filtering architecture."

The structure behind these social systems, called folksonomies, can be viewed as a tripartite hypergraph of user, tag and resource nodes. This underlying network shows specific structural properties that explain its growth and the possibility of serendipitous exploration.####Today’s search engines represent the gateway to retrieve information from the World Wide Web. Short queries typically consisting of two to three words describe a user’s information need. In response to the displayed results of the search engine, users click on the links of the result page as they expect the answer to be of relevance.####This clickdata can be represented as a folksonomy in which queries are descriptions of clicked URLs. The resulting network structure, which we will term logsonomy is very similar to the one of folksonomies. In order to find out about its properties, we analyze the topological characteristics of the tripartite hypergraph of queries, users and bookmarks on a large snapshot of del.icio.us and on query logs of two large search engines. All of the three datasets show small world properties. The tagging behavior of users, which is explained by preferential attachment of the tags in social bookmark systems, is reflected in the distribution of single query words in search engines. We can conclude that the clicking behaviour of search engine users based on the displayed search results and the tagging behaviour of social bookmarking users is driven by similar dynamics."

Here we introduce and evaluate network-based visualizations for facilitating the exploration of a Web knowledge space. We developed a force directed network interface to visualize the result sets provided by GiveALink.org, a social bookmarking site. The classifications and tags by users are aggregated to build a social similarity network between bookmarked resources. We administered a user study to evaluate the potential of leveraging such social links in an exploratory search task. During exploration, the similarity links are used to arrange the resources in a semantic layout. Users in our study prefer a hybrid interface combining a conventional ranked list and a two dimensional network map, allowing them to find the same amount of relevant information using fewer queries. This behavior is a direct result of the additional structural information present in the network visualization, which aids them in the exploration of the information space."

Because it is not only a hypertext but also adaptive it cannot simply be presented using a linear paper or a set of HTML pages. This paper describes the design of, and demonstrates AHA! (Version 3.0), an Open Source adaptive hypermedia platform, capable of performing content and link adaptation in (x)html and xml documents. Its development started in 1996. During 10 years of research and development different new presentation, adaptation and user modeling methods and techniques have been added, turning AHA! into a general-purpose adaptive hypermedia platform. This paper presents an overview of the design and architecture of AHA!, with parts that have been published before and with recent additions like style adaptation and a new very flexible link annotation mechanism. Unlike other adaptive hypermedia systems, AHA! is not aimed at a single application area and does not prescribe a single fixed presentation style. Creating applications, defining the user models and the adaptive behavior are all done using graphical authoring tools. End-users are presented with what looks like a normal website, and need not be aware of the adaptation that goes on behind the scenes. Their browsing results in updates to a user model that is stored either in an xml file or a mySQL database, and that is thus also (in principle) available to other applications. Apart from providing a design overview this paper highlights two essential parts of AHA!: the reasoning / rule engine that translates the end-user’s actions into user model updates, and the adaptive resource selection, which is used in the conditional inclusion of objects presentation technique and in the conditional link destinations navigation support technique. This paper is itself an adaptive hyperdocument. The order in which the different topics are visited determines the links that are presented and the contents of each (web)page. No matter how you browse through this paper you should end up with a very similar overall impression, and you should have seen all the information the paper contains. However, the actual contents of the pages and the actual link destinations do depend on your browsing order, so different users will not see exactly the same pages and links."

After discussing the ways in which plot may be varied, I describe the use of stretchtext as a reaction against the perceived incoherence of classic hypertext narrative, demonstrate the limitations that conventional stretchtext necessarily imposes on hypertext narrative, and describe an implemented generalization of stretchtext that matches the expressive and formal capabilities of classical hypertext systems while appearing to be a mere stretchtext and while running within the confines of a Web browser."

This was achieved by selecting narrative atoms, in this case photographs, from a selection of images on a specific subject with relevance to a desired theme. Our pilot study shows that our thematic system selects images with greater relevance to desired titles, and that the positive impact of thematic selection increases when the images are presented together.

Tag clouds represent variables of interest (such as popularity) in the visual appearance of the keywords themselves - using text properties such as font size, weight, or colour. Although tag clouds are becoming common, there is still little information about which visual features of tags draw the attention of viewers. As tag clouds attempt to represent a wider range of variables with a wider range of visual properties, it becomes difficult to predict what will appear visually important to a viewer. To investigate this issue, we carried out an exploratory study that asked users to select tags from clouds that manipulated nine visual properties. Our results show that font size and font weight have stronger effects than intensity, number of characters, or tag area; but when several visual properties are manipulated at once, there is no one property that stands out above the others. This study adds to the understanding of how visual properties of text capture the attention of users, indicates general guidelines for designers of tag clouds, and provides a study paradigm and starting points for future studies. In addition, our findings may be applied more generally to the visual presentation of textual hyperlinks as a way to provide more information to web navigators."

At a global level, we observe that although each individual’s corpus of visited sites is permanently growing, his browsing practices are structured around routine well-known sites which operate as links providers to new sites. We argue that this tension between the known and the unknown is constitutive of Web practices and is a fundamental property of personal Web territories."

First, this study characterizes the degree to which users re-tag previously published items and reuse tags: 10 to 20% of the daily activity can be characterized as re-tagging and about 75% of the activity as tag reuse. Second, we use the pairwise similarity between users’ activity to characterize the interest sharing in the system. We present the interest sharing distribution across the system, show that this metric encodes information about existing usage patterns, and attempt to correlate interest sharing levels to indicators of collaboration such as co-membership in discussion groups and semantic similarity of tag vocabularies. Finally, we show that interest sharing leads to an implicit structure that exhibit a natural segmentation.

Both the lack of structure and their time based nature pose difficulties for navigation in web lectures. The approach presented in this paper applies the basic concept of social navigation to facilitate navigation in web lectures. Social navigation support has been successfully employed for hypertext and picture augmented hypertext in the education domain.

This paper surveys annotation techniques from open hypermedia systems, Web based annotation systems, and mobile and augmented reality systems to illustrate different approaches to four central challenges ubiquitous annotation systems have to deal with: anchoring, structuring, presentation, and authoring. Through a number of examples each challenge is discussed and HyCon, a context-aware hypermedia framework developed at the University of Aarhus, Denmark, is used to illustrate an integrated approach to ubiquitous annotations. Finally, a taxonomy of annotation systems is presented. The taxonomy can be used both to categorize system based on the way they present annotations and to choose the right technology for interfacing with annotations when implementing new systems."

We illustrate how this information can provide valuable insights to Wikipedia’s editor community."

The goal of this work is to automatically suggest routes that are not only short but also emotionally pleasant. To quantify the extent to which urban locations are pleasant, we use data from a crowd-sourcing platform that shows two street scenes in London (out of hundreds), and a user votes on which one looks more beautiful, quiet, and happy. We consider votes from more than 3.3K individuals and translate them into quantitative measures of location perceptions. We arrange those locations into a graph upon which we learn pleasant routes. Based on a quantitative validation, we find that, compared to the shortest routes, the recommended ones add just a few extra walking minutes and are indeed perceived to be more beautiful, quiet, and happy. To test the generality of our approach, we consider Flickr metadata of more than 3.7M pictures in London and 1.3M in Boston, compute proxies for the crowdsourced beauty dimension (the one for which we have collected the most votes), and evaluate those proxies with 30 participants in London and 54 in Boston. These participants have not only rated our recommendations but have also carefully motivated their choices, providing insights for future work."

However, such navigational user interfaces are only useful to the extent that they expose the underlying topology—or network structure—of the information space. Yet, little is known about which topological clues should be integrated in navigational user interfaces. In detail, the aim of this paper is to identify what kind of and how much topological information needs to be included in user interfaces to facilitate efficient navigation. We model navigation as a variation of a decentralized search process with partial information and study its sensitivity to the quality and amount of the structural information used for navigation. We experiment with two strategies for node selection (quality of structural information provided to the user) and different amount of information (amount of structural information provided to the user). Our experiments on four datasets from different domains show that efficient navigation depends on the kind of structural information utilized. Additionally, node properties differ in their quality for augmenting navigation and intelligent pre-selection of which nodes to present in the interface to the user can improve navigational efficiency. This suggests that only a limited amount of high quality structural information needs to be exposed through the navigational user interface."

TweetClass employs a two-step, interactive process to support the determination of gender and age attributes. At each step, the user is presented with feedback on the confidence levels of the automated analysis and can choose to refine ambiguous cases by examining key profile and content data.

To address this lack of understanding, based on a theoretical framework, we present an analysis of the structural, influential, and contextual aspects of Like activities from the test datasets of 20 million users and their 2 billion Like activities in Instagram. Our study results first highlight that Like activities and networks increase exponentially, and are formed and developed by one’s friends and many random users. Second, we observe that five other essential Instagram elements influence the number of Likes to different extents, but following others will not necessarily increase the number of Likes that one receives. Third, we explore the relationship between LDA-based topics and Likes, characterize two user groups-specialists and generalists-and show that specialists tend to receive more Likes and promote themselves more than generalists.

Interpreting such data is extremely challenging, however. We present a longitudinal data-driven analysis of fine-grained interaction data captured from 14,000 recurrent users over 12 months. At the core of our approach is the aggregation of low-level interaction data into micro behaviours. By analysing changes in these behaviours as a function of users’ accumulated interaction time, we were able to demonstrate how users’ interaction evolves as they become more familiar with a Web page.

The resulting system of classification is referred to as a folksonomy. The uncontrolled nature of tags leads to inconsistencies in the usage of terms which impairs the utility of the system. Approaches to this problem that map tags to concepts of external knowledge representations, such as ontologies, are often inapplicable since they require that corresponding concepts exist and that they reflect the meaning of tags as intended by the users. In this paper, we present the notion of implicit tag relations. Our aim is to improve the accessibility of contents in tagging systems without significantly reducing the flexibility and universal applicability of tags. Instead of explicitly relating tags to each other, we propose to give users the ability to retroactively alter folksonomies by changing the tags of many resources with a single operation. This way, the usage of tags can be harmonized and it can be controlled how they are used in combination. We highlight the benefits of our approach compared to explicit tag relations and discuss important implications as well as its limitations."

With the growing popularity of such platforms, it is important for community managers to constantly monitor the performance of their communities. Although different metrics have been proposed for tracking the evolution of such communities, maturity, the process in which communities become more topic proficient over time, has been largely ignored despite its potential to help in identifying robust communities. In this paper, we interpret community maturity as the proportion of complex questions in a community at a given time. We use the Server Fault (SF) community, a Question Answering (Q&A) community of system administrators, as our case study and perform analysis on question complexity, the level of expertise required to answer a question. We show that question complexity depends on both the length of involvement and the level of contributions of the users who post questions within their community. We extract features relating to askers, answerers, questions and answers, and analyse which features are strongly correlated with question complexity. Although our findings highlight the difficulty of automatically identifying question complexity, we found that complexity is more influenced by both the topical focus and the length of community involvement of askers. Following the identification of question complexity, we define a measure of maturity and analyse the evolution of different topical communities. Our results show that different topical communities show different maturity patterns. Some communities show a high maturity at the beginning while others exhibit slow maturity rate."

Unlike carefully authored news text and other longer content, tweets pose a number of new challenges, due to their short, noisy, context-dependent, and dynamic nature. Semantic annotation of tweets is typically performed in a pipeline, comprising successive stages of language identification, tokenisation, part-of-speech tagging, named entity recognition and entity disambiguation (e.g. with respect to DBpedia). Consequently, errors are cumulative, and earlier-stage problems can severely reduce the performance of final stages. This paper presents a characterisation of genre-specific problems at each semantic annotation stage and the impact on subsequent stages. Critically, we evaluate impact on two high-level semantic annotation tasks: named entity detection and disambiguation. Our results demonstrate the importance of making approaches specific to the genre, and indicate a diminishing returns effect that reduces the effectiveness of complex text normalisation."

Storyscope is a web-based environment for constructing and exploring museum narratives and their underlying concepts. Storyscope aligns with a formal model of story and narrative specialized for a museum context called the curate ontology. This paper will explore the plot-reasoning component of Storyscope that provides intelligent support for the selection of events within the story and their interconnection as a coherent structure to be told within the narrative. Plot reasoning uses both internal knowledge and external information sources, such as Freebase and Factforge, to propose events that can be used to incrementally develop storylines and to emplot a museum narrative. The approach taken uses the notions of setting and theme to search and rank events in terms of their relevance to the developing storyline. This paces the expansion of the story in each step, ensures that the story develops in a direction that is of interest to the author and helps to maintain narrative cohesion, an important goal of story-building. Plot development is also supported by methods for clustering events into related plot elements and by using information from Freebase to propose different types of influence relations between story events."

Some implicit semantic associations might be calculable as the result of a computation but in some cases it is difficult for a computation to capture the purpose of a semantic association, for example, the semantic similarities embodied by synonyms and similar word/phrase likenesses are not easily specified in a general rule. It is possible however to capture semantic associations made by human searchers. Searchers interact with search results by clicking on one or more resources in a set of results, and this interaction takes two forms: the first being an implicit indication of the relevance of the search term to the chosen resource, and the second being an implicit indication of the mutual relevance of any two or more resources selected from the same search. Both have been proposed as a similarity measure for clustering of resources. In this paper we implement, evaluate and compare three methods for semantic association discovery, mined from Web search logs. The first method is based purely on query analysis, the second is single click-based, and the third is coselection-based. The methods are compared for their effectiveness at detecting semantic similarities."

In previous work on the Canyons, Deltas and Plains (CDP) model we argued that they are best considered as a form of sculptural hypertext, but sculptural hypertext is a relatively unexplored medium with few examples, and limited critical theory. This means that there is little guidance for authors on what is possible with the medium, and no common authoring tools, both of which impede adoption and experimentation. In this paper we describe our work to tackle this problem by working with creative writing students to create 40 location based sculptural hypertexts using an approach similar to paper-prototyping, and then analysing these for common patterns (structures of nodes, rules, and conditions used for a poetic purpose). We present seven key patterns: Parallel Threads, Gating, Concurrent Nodes, Alternative Nodes, Foldbacks, Phasing, and Unlocking. In doing so we see some overlap with the patterns identified in traditional (calligraphic) hypertext, but in many cases these patterns are particularly suited to sculptural hypertext, and hint at a different poetics for the form. Our findings refine our original CDP model, but also present a starting point for educating writers on how to approach sculptural stories, and form a foundation for future location-based authoring tools."

This supports expressing information structures implicitly and in an intuitive way. However, automatic recognition of such informal, implicitly encoded structures by a machine (a so-called spatial parser) is still a challenge. Conventional parsers are conceptually restricted by their underlying source of information. Due to this limitation there are various possible structures that cannot be recognized properly, as the machine has no means to detect them. This inevitably limits both the quality of parser output and hence parser performance. In this paper we show that considering temporal aspects in spatial parser design will lead to significant increase in parsing accuracy, detection of richer structures and thus higher parser performance. We call machines that consider such spatial and temporal information spatio-temporal parsers.####For the purpose of providing evidence, parsers for recognizing spatial, visual, and temporal object relations have been implemented and tested in a series of user surveys. One aim was to find out how “close” the machine interpretetation of structures get to human interpretation. It turned out that in none of the test cases pure spatial or visual parser could outperform the spatio-temporal parser. Instead, the spatio-temporal parser was able to compensate limitations of conventional parsers. Furthermore, we have statistically tested parsing accuracy. The results indicate a non-trivial effect that is recognizable by humans. This shows that spatio-temporal parsers produce output that is significantly closer to what knowledge workers intend to express compared to traditional spatial parsers."

In this work, we thrive to explain and uncover the features of airline reviews that contribute most to traveler satisfaction. To that end, we examine reviews crawled from the Skytrax air travel review portal. Skytrax provides four review categories to review airports, lounges, airlines and seats. Each review category consists of several five-star ratings as well as free-text review content. In this paper, we conduct a comprehensive feature study and we find that not only five-star rating information such as airport queuing time and lounge comfort highly correlate with traveler satisfaction but also inferred features in the form of the review text sentiment. Based on our findings, we create classifiers to predict traveler satisfaction using the best performing rating features. Our results reveal that given our methodology, traveler satisfaction can be predicted with high accuracy. Additionally, we find that training a model on the sentiment of the review text provides a competitive alternative when no five-star rating information is available. We believe that our work is of interest for researchers in the area of modeling and predicting user satisfaction based on available review data on the Web."

The perception of Twitter as a space for serendipitous experiences is fueled by its dynamic qualities, trigger rich interface, and networked nature, which have the potential to prompt unexpected encounters with information and ideas. The present paper examined 184 individuals’ use of Twitter features in relation to their perceptions of Twitter as serendipitous and tested for the influence of demographic differences.

We surveyed 100 workers of the CrowdFlower platform to verify the presence of issues with task clarity in crowdsourcing marketplaces, reveal how crowd workers deal with such issues, and motivate the need for mechanisms that can predict and measure task clarity. Next, we propose a novel model for task clarity based on the goal and role clarity constructs. We sampled 7.1K tasks from the Amazon mTurk marketplace, and acquired labels for task clarity from crowd workers. We show that task clarity is coherently perceived by crowd workers, and is affected by the type of the task. We then propose a set of features to capture task clarity, and use the acquired labels to train and validate a supervised machine learning model for task clarity prediction. Finally, we perform a long-term analysis of the evolution of task clarity on Amazon mTurk, and show that clarity is not a property suitable for temporal characterisation."

To explore these poetics we present a co-operative inquiry into the authoring of an interactive location-based narrative, ‘The Isle of Brine’, set on the island of Tiree. Our inquiry reveals both pragmatic and aesthetic considerations driven by the locations themselves, that affect the design of both the Story (narrative structure) and Fabula (events within the story). These include the importance of paths, bottlenecks, and junctions as a physical manifestation of calligraphic patterns, the need for coherent narrative areas, and the requirement to use evocative places and to manage thematic and tonal discord between the landscape and the narrative."

However, with the claim to also support other structure domains than node-link structures, hypertext systems had to overcome some challenges. Researchers came up with component-based approaches and low level structure services.####Due to the raising omnipresence of the Web, research on traditional hypertext systems has been fading out over the past decade. This paper focuses again on hypertext infrastructures and goes beyond ongoing Web discussions. Based on lessons learned from well thought through previous work, we present a novel design for multi-structure supporting, general purpose hypertext systems that can be used in a series of application domains. The system provides intelligence analysis which is needed for sophisticated user support. We argue that this lets us use the hypertext system also as a visual analytics tool. Furthermore, for demonstration purposes we describe the use of the system in combination with a Web-based software engineering platform, which is part of the ongoing project ODIN."

Large numbers of (potential) editors are not necessarily a suffcient bulwark against loss of coherence amongst a corpus of many discrete articles. The longitudinal task of curation may benefit from deliberate curatorial roles and techniques.####A potentially beneficial technique for the development and maintenance of hypertext content at scale is hypertext transclusion, by offering controllable re-use of a canonical source. In considering issues of longitudinal support of web collaborative hypertexts, we investigated the current degree and manner of adoption of transclusion facilities by editors of Wikipedia articles. We sampled 20 million articles from ten discrete language wikis within Wikipedia to analyse behaviour both within and across the individual Wikipedia communities.####We show that Wikipedia makes limited, inconsistent of use of transclusion (as at February 2016). Use is localised to subject areas, which differ between sampled languages. A limited number of patterns were observed including: Lists from transclusion, Lists of Lists, Episodic Media Listings, Tangles, Articles as Macros, and Self-Transclusion. We find little indication of deliberate structural maintenance of the hypertext."

To our knowledge, this is one of the first studies to comprehensively examine brands by incorporating user-generated social content and information about user interactions. This paper makes several important contributions. We build and normalize a weighted, undirected network representing interactions among users and brands. We then explore the structure of this network using modified network measures to understand its characteristics and implications. As a part of this exploration, we address three important research questions: (1) What is the structure of a brand-brand network? (2) Does an influential brand have a large number of fans? (3) Does an influential brand receive more positive or more negative comments from social users? Experiments conducted with Facebook data show that the influence of a brand has (a) high positive correlation with the size of a brand, meaning that an influential brand can attract more fans, and, (b) low negative correlation with the sentiment of comments made by users on that brand, which means that negative comments have a more powerful ability to generate awareness of a brand than positive comments. To process the large-scale datasets and networks, we implement MapReduce-based algorithms."

In this paper, we propose a two-level categorization scheme for tasks, based on an extensive study of 1000 workers on CrowdFlower. In addition, we present insights into certain aspects of crowd behaviour; the task affinity of workers, effort exerted by workers to complete tasks of various types, and their satisfaction with the monetary incentives."

We show how this observation contributes to (i) a better understanding of language-agnostic user classification on Twitter, (ii) eliciting opportunities for Computational Social Science, and (iii) improving online marketing by identifying cross-selling opportunities. We start with a machine learning problem of predicting a user’s preference among two alternative choices of Twitter friends. We show that co-following information provides strong signals for diverse classification tasks and that these signals persist even when the most discriminative features are removed. Going beyond mere classification performance optimization, we present applications of our methodology to Computational Social Science. Here we confirm stereotypes such as that the country singer Kenny Chesney (@kennychesney) is more popular among @GOP followers, whereas Lady Gaga (@ladygaga) enjoys more support from @TheDemocrats followers.####In the domain of marketing we give evidence that celebrity endorsement is reflected in co-following and we demonstrate how our methodology can be used to reveal the audience similarities between not so obvious entites such as Apple and Puma."

Exercising in the park, shopping for groceries, falling asleep, or even taking a shower, are just some of the everyday real-world activities that are likely to generate data. This is the big data world of the so-called Sensor Web. It is enabled by the widescale availability of high-performance computing, always-on communications, and mobile computing devices that come equipped with a variety of powerful sensors. This provides for a powerful computing and sensing ecosystem with important applications across all aspects of how we live, work, and play.####The primary challenge for us now is to understand how we can (and whether we should) use this information. On the one hand, the promise of big data analytics is better decisions: better decisions about where we might live or where to send our kids to school; better decisions about the food we eat and the exercise we should take; and better decisions about some of the biggest choices facing modern societies when it comes to health, education, energy, and climate. On the other hand, this potential has a darker side, in the form of a gradual erosion of personal privacy as businesses and even governments seek to exploit our personal data for their own purposes, often without our informed consent.####What is certain is that the combination of mobile computation, cheap but powerful sensors, and big data analytics points to new ways of thinking about some of society’s toughest challenges. But to take advantage of these benefits we must reconcile the promise of big data with the pitfalls of privacy. Only then can these technologies can have a meaningful impact on how we can all benefit from the big data revolution as part of a healthier, safer, fairer world.####[no references]"

Some Adaptive Systems use a closed corpus content that has been prepared for them a priori, hence, they accept only a narrow field of content. Furthermore, the content is tightly coupled with other parts of the system, which also hinders its re-usability. To address these limitations, recent systems started to make use of open Web content to provide a wider variety of content. Previous approaches have attempted to harness the information available on the web by providing adaptive systems with customizable information objects. Since adaptive systems are evolving towards the Semantic Web and the use of ontologies, existing systems are limited by their ability to service these documents solely through keyword-based queries. In this research we propose a novel framework that extends existing content provision system, Slicepedia. Our framework uses the conceptual representation of content to segment it in a semantic manner. The framework removes unnecessary content from web pages, such as navigation bars, and then semantically reveals the structural representation of text to build a tree-like hierarchy. This tree can be traversed to obtain different levels of content granularity that facilitate content discoverability and adaptivity."

But tools meant to help often do the opposite-pulling people and their information in different directions. Fragmentation is potentially worsened as personal information moves onto the Web and into a myriad of special-purpose, mobile-enabled applications. How can tool developers innovate “non-disruptively” in ways that do not force people to re-organize or re-locate their information? This paper makes two arguments: 1. An integration of personal information is not likely to happen through some new release of a desktop operating system or via a Web-based “super tool.” 2. Instead, integration is best supported through the development of a standards-based infrastructure that makes provision for the shared manipulation of common structure by any number of tools, each in its own way. To illustrate this approach, the paper describes an XML-based schema, considerations in its design and its current use in three separate tools. The schema in its design and use builds on the lessons learned by the open hypermedia and structural computing communities while moving forward with new techniques that address some of the changes introduced by the evolution of the term “application” to move beyond desktop apps to mobile apps, cloud-based apps and various hybrid architectures."

Determining an empirical measure of significance of a group can help tackle this problem. The proposed framework therefore determines an optimal measure per group based on past user participation and interaction as well as likely future activity in the group. The framework is tested on a Flickr dataset and the results show that this method can yield satisfactory predictions of group activity. This implies that the computed measure of significance of a group can be used by end users to choose groups with rich activity."

To support that, a general framework for an authoring tool is proposed through two main phases. During the first phase, an automatic and parameterized transformation is applied on the input activity trace to generate a fragmented document. Each fragment describes one or many observed elements of the modeled trace and relations between fragments are deduced from relations between these elements. The second phase consists in interactive transformations on the intermediate produced document until getting the final hypermedia document.

Large numbers of most popular sites on the Web are currently mainstream Web 2.0 applications with rich user-generated content. Wikipedia, YouTube, Flickr, and del.icio.us are classical examples of those sites.####Web 2.0 allows users to do more than just retrieving information, since it is based upon architecture of participation that reduces the barriers of online collaboration and encourages the generation and distribution of content. For this reason it is also called as Social Web. Users are encouraged to provide data and metadata in simple ways such as tagging, ratings, comments, and blogging. As a result, Web 2.0 applications are collecting large amount of data. However, this data is poorly structured, highly subjective and often buried in a low-quality content. The more data, the more challenging it becomes for users to find relevant information. Social web applications prefer not to deal with this problem and simply present this content to users as it is, in a form of fuzzy aggregations, such as scattered tag clouds and folksonomies that become very confusing and ineffective for users.####Adding formal semantics to tags can be an important step in the direction of a better navigation and searching and should help to transform tag clouds and folksonomies into valuable aggregations representing a sort of “collective knowledge”.####There is the opportunity to exploit such Web 2.0 collective knowledge (together with the individual user knowledge) in order to achieve the vision of Web 3.0.####[no references]"

For example, we browse the Web [2], search for connections among friends in social networks, follow leads in citation networks[6, 3], of scientific literature, and look up things in cross-referenced dictionaries and encyclopedias. Even though navigating networks is an essential part of our everyday lives, little is known about the mechanisms humans use to navigate networks as well as the properties of networks that allow for efficient navigation.####We conduct two large scale studies of human navigation in networks. First, we present a study an instance of Milgram’s small-world experiment where the task is to navigate from a given source to a given target node using only the local network information [5]. We perform a computational analysis of a planetary-scale social network of 240 million people and 1.3 billion edges and investigate the importance of geographic cues for navigating the network. Second, we also discuss a large-scale study of human wayfinding, in which, given a network of links between the concepts of Wikipedia, people play a game of finding a short path from a given start to a given target concept by following hyperlinks (Figure 1) [7]. We study more than 30,000 goal-directed human search paths through Wikipedia network and identify strategies people use when navigating information spaces.####Even though the domains of social and information networks are very different, we find many commonalities in navigation of the two networks. Humans tend to be good at finding short paths, despite the fact that the networks are very large [8]. Human paths differ from shortest paths in characteristic ways. At the early stages of the search navigating to a high-degree hub node helps, while in the later stage, content features and geography provide the most important clues. We also observe a trade-off between simplicity and efficiency: conceptually simple solutions are more common but tend to be less efficient than more complex ones [9].####One potential reason for good human performance could be that humans possess vast amounts of background knowledge about the network, which they leverage to make good guesses about possible paths. So we ask the question: Are human-like high-level reasoning skills really necessary for finding short paths? To answer this question, we design a number of navigation agents without such skills, which use only simple numerical features [8]. We evaluate the agents on the task of navigating both networks. We observe that the agents find shorter paths than humans on average and therefore conclude that, perhaps surprisingly, no sophisticated background knowledge or high-level reasoning is required for navigating a complex network."

While traditional studies aim to learn the similarities and differences between these communities via high-cost user studies, in this paper we propose a much more efficient method to compare different communities by utilizing social media. Specifically, Weibo and Twitter, the two largest microblogging systems, are employed to represent the target communities, i.e. China and the Western world (mainly United States), respectively. Meanwhile, through the analysis of the Wikipedia page-click log, we identify a set of categorical ‘hot events’ for one month in 2012 and search those hot events in Weibo and Twitter corpora along with timestamps via information retrieval methods. We further quantitatively and qualitatively compare users’ responses to those events in Twitter and Weibo in terms of three aspects: popularity, temporal dynamic, and information diffusion. The comparative results show that although the popularity ranking of those events are very similar, the patterns of temporal dynamics and information diffusion can be quite different."

Users are often asked to reformulate their needs, adding specific details, providing examples, or simply clarifying the context of their requests. Formulating a good question is a task that might require several interactions between the asker and other community members, thus delaying the actual answering and, possibly, decreasing the interest of the community in the issue.

Video can enhance the realism and authenticity of a learning environment. By adding structure and interactivity to video, hypervideo allows to navigate video and to explore other related media to complement it. Hypervideo might then support the creation of a rich and realistic learning environment, through the interactive access, construction and communication of knowledge on veterinary surgery. In this paper, we present the design and evaluation of Hvet, a hypervideo environment to support learning of veterinary surgery. Design was based on cognitive and media theories, and evaluation was based on the use of Hvet by veterinary students, in order to test its efficacy in substitution of learning and training with live animals. Results support the hypothesis, showing the potential of hypervideo as a valuable and effective tool to support learning of surgery techniques and revealing the most appreciated design options."

New tools are being created that facilitate the interactions between these networks, greatly expanding the role of hypertext as a social media tool. Interactive visualization is a particularly powerful tool that capitalizes on the immense visual processing power of the human brain. With Web 2.0 and related technologies the world of ideas is being shaped by the wisdom of crowds. People understand data better when we scale up the audience. While one can learn a lot simply watching visual displays of information, there is also a pent up desire to analyze. People want their own controls, so that they can see data in their own way by looking at it differently. ManyEyes is a system that features a range of visualizations, where people can upload data and see that data in a variety of ways. When people find interesting views of the data they can annotate them and share their comments with others, thus building a community around visualization and interpretation. Sharing visualizations and interpretations lets people have deeper discussions in the communities that they belong to, facilitating conversations on politics, economics, health, and a host of other issues. We have found that visualizations are particularly powerful when used to analyze words. Dynamic visualizations draw people in and lead to interesting new conclusions. Scalable real world deployments let research keep up with the wisdom of crowds, and this keynote will explore some of the emerging research in this area.

The results indicate that coselection can be used in this way. We ground-truthed unambiguous query clustering, forming a foundation for work on automatic ambiguity detection based on the resulting number of generated clusters.

We solve shortcomings of existing adaptive systems in terms of genericity, extensibility and usability and show how GALE improves on the state of the art in all these aspects. We illustrate different authoring styles for GALE, including the use of template pages, and show how adaptation can be defined in a completely decentralized way by using the open corpus adaptation facility of GALE.

Given the scale of the potential result sets, how does one identify the ‘best’ or ‘right’ set of items? We explore a solution that aligns characteristics of the information space, including specific content attributes and the information diversity of the results set, with measurements of human information processing, including engagement and recognition memory. Using Twitter as a test bed, we propose a greedy iterative clustering technique for selecting a set of items on a given topic that matches a specified level of diversity.####In a user study, we show that our proposed method yields sets of items that were, on balance, more engaging, better remembered, and rated as more interesting and informative compared to baseline techniques. Additionally, diversity indeed seemed to be important to participants in the study in the consumption of content. However as a rather surprising result, we also observe that content was perceived to be more relevant when it was highly homogeneous or highly heterogeneous. In this light, implications for the selection and evaluation of topic-centric item sets in social media contexts are discussed."

In this work, we propose an Adaptive Privacy Policy Prediction (A3P) system to help users compose privacy settings for their images. In particular, we examine the role of image content and metadata as possible indicators of users’ privacy preferences. We propose a two-level image classification framework to obtain image categories which may be associated with similar policies. Then, we develop a policy prediction algorithm to automatically generate a policy for each newly uploaded image. Most importantly, the generated policy will follow the trend of the user’s privacy concerns evolved with time. We have conducted an extensive user study and the results demonstrate effectiveness of our system with the prediction accuracy around 90%."

At Hypertext 2011 Pisarski [12] suggested that to refocus on nodes in hypertext might unlock a new poetics, and at Hypertext 2001 Bernstein [3] lamented the lack of strange hypertexts: playful tools that experiment with hypertext structure and form. As part of the emerging Strange Hypertexts community project we have been exploring a number of exotic hypertext tools, and in this paper we set out an early experiment with media and creative writing undergraduates to see what effect one particular form—Fractal Narratives, a hypertext where readers drill down into text in a reoccurring pattern—would have on their writing. In this particular trial, we found that most students did not engage in the structure from a storytelling point of view, although they did find value from a planning point of view. Participants conceptually saw the value in non-linear storytelling but few exploited the fractal structure to actually do this. Participant feedback leads us to conclude that while new poetics do emerge from strange hypertexts, this should be viewed as an ongoing process that can be reinforced and encouraged by designing tools that highlight and support those emerging poetics in a series of feedback loops, and by providing writing contexts where they can be highlighted and collaboratively explored."

While organic topics rely on values such as novelty and spread through bridging ties, artificial topics are based on bonding ties, with associated values such as engagement, cooperation and trust among the actors."

It has a strong focus on the user and thus is complementary to the strong machine analytics research direction that could be experienced in previous conferences. The user-centric view on hypertext not only includes user interfaces and interaction, but also discussions about hypertext application domains. Furthermore, the workshop raises the question of how original hypertext ideas (e.g., Doug Engelbart’s “augmenting human intellect” or Frank Halasz’ “hypertext as a medium for thinking and communication”) can improve today’s hypertext systems.####[no references]"

Though prior works have shown that the knowledge gain of collaborators can be influenced by user demographics and searching strategies in long-term collaborative learning, little is known about the effect of these factors on user knowledge gain in short-term collaborative web search. In this paper, we present a study addressing the knowledge gain of user pairs in single collaborative web search sessions. Using crowdsourcing we recruited 454 unique users (227 random pairs), who then collaboratively worked on informational search tasks spanning 10 different topics and information needs. We investigated how users’ demographics and traits, and the interaction between these factors could influence their knowledge gain. We found that in contrast to offline collaboration cases, user demographics such as gender, age, etc. do not significantly effect users’ knowledge gain in collaborative web search sessions. Instead, our results highlight the presence of labor division of queries and particular interaction patterns in communication that facilitate knowledge gain in user pairs. Based on these findings, we propose a multiple linear regression model to predict the knowledge gain of users in collaborative web search sessions from the perspective of team composition."

Launched in 2017 as an alternative to YouTube, BitChute joins an ecosystem of alternative, low content moderation platforms, including Gab, Voat, Minds, and 4chan. Uniquely, BitChute is the first of these alternative platforms to focus on video content and is growing in popularity. Our analysis reveals several key characteristics of the platform. We find that only a handful of channels receive any engagement, and almost all of those channels contain conspiracies or hate speech. This high rate of hate speech on the platform as a whole, much of which is anti-Semitic, is particularly concerning. Our results suggest that BitChute has a higher rate of hate speech than Gab but less than 4chan. Lastly, we find that while some BitChute content producers have been banned from other platforms, many maintain profiles on mainstream social media platforms, particularly YouTube. This paper contributes a first look at the content and discourse on BitChute and provides a building block for future research on low content moderation platforms."

This is particularly true for creative people who have personalized patterns of gathering, organizing, and presenting information from a variety of sources. Moreover, each application comes with its own learning curve and data model, restricting users seeking to extend their workflows and in some cases, losing data through poor data transferring mechanisms such as clipboard copy and paste.####Dash is an open component-based hypermedia system that provides what we believe to be a best of breed set of components. While each component can be used in isolation as less full featured versions of an analogous application, Dash allows users to interoperate components and compose their own workflows without losing data or expending effort while switching between tasks. As hypertext allowed users to flexibly move between texts, Dash allows users to flexibly move between tasks."

We propose a credibility analysis approach based on the linguistic structure of the tweets. We not only characterize the Twitter events but also predict their perceived credibility of them by a novel deep learning architecture. We use the huge CREDBANK data to conduct our experiments. Some of our exciting findings are that standard LIWC categories like ‘negate’, ‘discrep’, ‘cogmech’, ‘swear’ and the Empath categories like ‘hate’, ‘poor’, ‘government’, ‘worship’ and ‘swearing-terms’ correlate negatively with the credibility of events. While some of our results resonate with the earlier literature others represent novel insights of the fake and legitimate twitter events. Using the above observations and the current deep learning architecture we predict the credibility of an event (a four-class classification problem in our case) with an accuracy of 0.54 that improves the best-known state-of-the-art (current accuracy 0.43) by ~ 26%. A fascinating observation is that even by looking at the first few tweets of an event, it is possible to make the prediction almost as accurate as in the case where the entire volume of tweets is observed.####[no references]"

We compare this attribute with other features of the platform to form a better understanding of the data and the digital behaviours they capture, and show how this Facebook attribute relates to mobile phone penetration rates and gender gaps in mobile access. We find that this “Uses a mobile device (X months)” advertising targeting attribute can be used as a proxy for changes in mobile phone penetration rates, especially among younger users, and that it captures cross-national variation in mobile gender gaps. We further find that countries with larger gender gaps disfavoring women are comparatively more gender-equal among the most recently joined cohort."

In this paper, we describe a method for predicting the occupational class and the income of Twitter users given information extracted from their extended networks by learning a low-dimensional vector representation of users, i.e. graph embeddings. We use this representation to train predictive models for occupational class and income. Results on two publicly available datasets show that our method consistently outperforms the state-of-the-art methods in both tasks. We also obtain further significant improvements when we combine graph embeddings with textual features, demonstrating that social network and language information are complementary."

Governments and NGOs are tracking information that doesn’t begin in electronic format, like school refurbishments and job trainings, then storing it in unstructured documents on inaccessible hard drives around the globe. DevResults is a private software company with the objective of providing best-in-class tools for managing data in international development. The aim is to enable data-driven decision-making by international development practitioners and the communities they serve. If properly captured, shared, and interpreted, international development data offer insights on how to reduce disease, improve education, and lift people out of poverty. DevResults is approaching this problem with a Software as a Service (SaaS) model, paired with consulting and training on designing metrics, structuring data, and using web-based tools. Over the last decade, DevResults has developed an iterative approach based on user feedback from thousands of users of over 100 product instances. This has produced an increasingly sophisticated application and complex data model as demand grows for linked, interoperable data. Among other lessons learned, DevResults has identified a key precept of only revealing complexity where needed, as organizations and users express a wide range of needs and capacities. The result is a commercially viable product that’s modular in design. DevResults’ software is in use at all organizational levels and has dramatically improved data management and analysis for user organizations."

However, in the absence of domain knowledge it is imperative to define key concepts and their relationship in the text for correct interpretation for general readers. To address this, we propose a text enrichment framework that identifies the key concepts from input text, highlights definitions and fetches the definition from external data sources in case the concept is undefined. Beyond concept definitions, the system enriches the input text with concept applications and a pre-requisite concept graph that showcases the inter-dependency within the extracted concepts. While the problem of learning definition statements is attempted in literature, the task of learning application statements is novel. We manually annotated a dataset for training a deep learning network for identifying application statements in text. We quantitatively compared the results of both application and definition identification models with standard baselines. To validate the utility of the proposed framework for general readers, we report enrichment accuracy and show promising results."

This has meant that they are short-lived, the narratives have been constructed by the creators of the system, and that the barrier to creating locative experiences has remained high due to a lack of common tools. We set out to create a platform based on the commonalities of these historic systems, with a focus on hypertext structure, and designed to enable locative based narratives to be created, deployed, and experienced in-the-wild. The result is StoryPlaces, an open source locative hypertext platform and authoring tool designed around a sculptural hypertext engine and built with existing Web technologies. As well as providing an open platform for future development, StoryPlaces also offers novelty in its management of location, including the separation of location and nodes, of descriptions from locations, and of content from pages, as well as being designed to have run-time caching and disconnection resilience. It also advances the state of the art in sculptural hypertext systems delivery through conditional functions, and nested, geographic and temporal conditions. The StoryPlaces platform has been used for the public deployment of over twenty locative narratives, and demonstrates the effectiveness of a general platform for delivering complex locative narrative experiences. In this paper we describe the process of creating the platform and our insights on the design of locative hypertext platforms."

However, while locative hypertext provides significant opportunities for rich locative applications for both education and entertainment, many applications in this space are tied to very specific locations, restricting their utility to local users. While this is necessary for some locative applications (such as tour guides), others make use of location as a thematic or contextual backdrop and as such could be effectively read in similar locations elsewhere. However, many locative systems are restricted to use specific prescribed locations, and systems that do generate locations do so in a simplistic manner, and often with mixed results. In this paper we propose a more intelligent generative approach to locative hypertext that will generate a locative structure for the user’s local area that both respects the thematic location demands of the piece and the effective patterns and structures of locative narrative.####[Winners of Blue Skies paper]"

It is in part, a characterization of the intent of the change.

I show that position of information in the user interface strongly determines whether it is seen, while explicit signals about its popularity increases the likelihood of response. Accounting for these factors simplifies dynamics of information diffusion, allows for more accurate prediction of social behavior, and explains why most memes fail to spread widely online."

This has meant that research into authoring tools has not sufficiently targeted specific activities, leading to complexity for users, and confusion over what research findings actually mean. In this paper we present a systematic literature review and analysis of all the papers published in ACM Hypertext (since 1987) and the International Conference on Interactive Digital Storytelling (ICIDS since 2008, and preceding events ICVS and TIDSE 2001-2007) that describe a distinct authoring activity. We discover seventeen papers that between them cover six common activities: Training/Support, Planning, Visualising/Structuring. Writing, Editing, and Compiling/Testing, as well as a seventh category for non-common Advanced activities for specialist domains. Planning and Editing tend to treat structure and content as a duality, while Structuring and Writing treat them as separate aspects of the digital narrative. All six activities have foundations in the Hypertext conference in its first decade, and have seen somewhat of a resurgence of interest in ICIDS in the last decade - although overall numbers are surprisingly low, especially given the size of the proceedings reviewed, indicating how little is known about the human experience of hypertext authoring. Our findings will help structure the work of those studying hypertext authoring and help focus the efforts of those developing new authoring applications."

There are versions of Monopoly and Tetris that, alone, seem to address subjects ranging from pop music, bass fishing, and sex to mass murder, slavery, and predatory real estate development. Yet for all but the last of these, the actual play of these games is at odds with the intended theme.####So what topics can games meaningfully address? One powerful way that games can address topics is by having playable models that resonate with their intended themes. Monopoly is actually an example of such a game, with a playable model of real estate development ripped off from a game intended as a critique of capitalism’s approach to resources. So is the less philosophical DOOM, with playable models of combat and space that match its “death travelogue” theme.####The foundation of any playable model is a set of operational logics, which combine communication and computation with opportunities for play. (Monopoly’s real estate model includes resource, pattern matching, and chance logics.) Video games depend on a relatively small vocabulary of such logics [1]. This restricts the playable models available, which is a challenge faced by those seeking to meaningfully address personal, cultural, and political topics through games [2].####One conspicuous counter-example, however, is the linking logic. The communicative role of the hypertext link is flexible enough that it can be used to address a wide range of topics. Yet the very flexibility of linking logics pushes the burden of systemic use onto game developers, which itself produces limits. Greater connection between video game research and hypertext research communities could be a path to address this."

Hand-selected collections of web pages about events shared by users on social media offer the opportunity for bootstrapping archived collections. We investigated if collections generated automatically and semi-automatically from social media sources such as Storify, Reddit, Twitter, and Wikipedia are similar to Archive-It human-generated collections. This is a challenging task because it requires comparing collections that may cater to different needs. It is also challenging to compare collections since there are many possible measures to use as a baseline for collection comparison: how does one narrow down this list to metrics that reflect if two collections are similar or dissimilar? We identified social media sources that may provide similar collections to Archive-It human-generated collections in two main steps. First, we explored the state of the art in collection comparison and defined a suite of seven measures (Collection Characterizing Suite - CCS) to describe the individual collections. Second, we calculated the distances between the CCS vectors of Archive-It collections and the CCS vectors of collections generated automatically and semi-automatically from social media sources, to identify social media collections most similar to Archive-It collections. The CCS distance comparison was done for three topics: “Ebola Virus,” “Hurricane Harvey,” and “2016 Pulse Nightclub Shooting.” Our results showed that social media sources such as Reddit, Storify, Twitter, and Wikipedia produce collections that are similar to Archive-It collections. Consequently, curators may consider extracting URIs from these sources in order to begin or augment collections about various news topics."

Martin Luther King and Robert Kennedy were assassinated. Hippie “flower power” and the closely related anti-Vietnam war movement were socio-political revolutions. In Europe, 2019 marks the 100th anniversary of the end of the “war to end all wars” and the 75th anniversary of D-Day. Counterpointing this societal turmoil, technology gave us hope. Neil Armstrong and Buzz Aldrin walked on the moon. Doug Engelbart and his team presented the “Mother of All Demos” of NLS at the ’68 Fall Joint Computer Conference. Ivan Sutherland’s pioneering Sketchpad (that demo’d interactive graphics in 1963) and Engelbart’s NLS demo were two landmark events that were early examples of interactive computing in an era of batch computation. Interactive computing on time-sharing systems, combined with microminiaturization, would lead more than a decade later to the birth of the personal computer. It caused a revolution in the dominant model of computing that was centered on large mainframes and minicomputers used for science and engineering, finance and commerce. Interactive computing based on computer graphics and its use in hypermedia systems characterizes most of my research career. In 2019, it is difficult to remember the impact that interaction-based information structuring and sharing had on society; it certainly shaped my research career. In this presentation, I will reflect on the development of five decades of hypermedia systems and will demo three systems that have been highlights of my journey in hyperland. First, I’ll show our FRESS hypertext system (still running 50-year old assembly code!), with the database of poetry used by a class of English students in 1976 in what is arguably the first online scholarly community. Next, I will demo our TAG (Touch Art Gallery) used by the Nobel Foundation a few years ago for a traveling exhibition on Alfred Nobel and all the Nobel Laureates. Finally, I’ll interweave the hypertext-centric parts of my talk with some source material stored in an unbounded 2D workspace, using our current hypermedia system Dash, which is still under development and in an early but already useful state. These systems will be presented in the context of the research trends that led, ultimately, to the interconnected society in which we live. All of us working on our first hypertext systems in the ‘60s understood the potential of this technology. What I did not predict is that 50 years later the revolution in human-centered computing would remain far too unfinished in terms of its positive societal impact. Indeed, that impact and utility are increasingly in jeopardy from a variety of forces, both economic and political. I will close with some thoughts on both deliberately designed and unanticipated societal issues of social media that I feel we technologists must urgently help address.####[no references]"

In this paper we describe a system that is based on related research in the fields of spatial hypertext, information retrieval, and visualization. It utilizes a 2D space on which users can add, remove, or manipulate information entities (so-called user nodes) visually. A spatial parser recognizes the evolving structure and queries a knowledge base for helpful other information entities (so-called suggestions nodes). Similar to user nodes, those suggestions are presented as visual objects in the space. We propose a physics model to simulate their behavior. Their characteristics encode the relevance of suggestions to user nodes and to each other. This enables human recipients to interpret the given visual clues and, thus, identify information of interest. The way users organize nodes spatially influences the parsed spatial structures, i.e., the placement of suggestion nodes. This allows the creation of complex queries without any prior knowledge, yet the users do not have to be aware of that, because they can express their thoughts implicitly by manipulating their nodes. We discuss the strengths of a physics based simulation to encode context visually and point to open issues and potential solutions. On the basis of an implemented demonstrator we show the benefits compared to similar and related applications in the field of information visualization, especially when it comes to tasks where a high portion of creativity is involved and the information space is not well known."

I demonstrate how AGA is an explicit database, supposedly showing a ‘complete’ archive, whereas haikU is an implicit database that hides the corpus of sentences. I show the sociality of the databases, thematizing both the human process behind database formation as a whole, as well as how the individual elements influence the perception of the overall database.

In the past, various hypermedia engines have been proposed to support these tasks. Until now, hypermedia engines either provided a fixed hypermedia data model and left extensions to the hypermedia application or they left the modeling of the hypermedia data completely to the application developer and only provided storage functionality which had to be plugged into the data model by the application developer. As an alternative, we propose an extensible object-oriented hypermedia engine which supports the specification of application semantics as application classes within the hypermedia engine, thereby supporting complex operations maintaining application-specific as well as application-independent constraints.####In the HyperStorM hypermedia engine, the storage layer and the application layer of a hypermedia system are implemented within the object-oriented database management system VODAK. Only the presentation layer is kept outside the 00DBMS. This approach facilitates both the reuse of database functionality as well as the flexibility necessary to support the efficient development of different kinds of hypermedia applications. First evaluations show that our approach presents a much more powerful hypermedia engine than previous approaches, thus giving a new quality to hypermedia application development."

Previous HyperDisco experiments have dealt with integration of a small set of tools supporting authoring and extension of the integrated tools to support multiple collaborating users and multiple versions of shared files. These experiments were conducted on a local area network using a single centralized workspace. The latest version of Hyper-Disco supports collaboration and versioning over multiple workspaces distributed across the Internet. This paper gives a brief overview of HyperDisco, describes the workspace concept and reports on the latest experiments: (1) an experiment that allows the use of multiple workspaces on a local area network, (2) an experiment that allows workspaces to be distributed across the Internet, and (3) an experiment focusing on hypermedia modeling and presentation issues of distributed workspaces."

This work tries to solve these problems 1) by developing a flexible hypertext meta-model which can represent activity space semantics, 2) developing an example-based definition tool for users to create task-specific activity spaces, 3) providing intelligent aid in using these activity spaces, and 4) providing a flexible space for adopting existing and emergent patterns. A system (COWFISH) with the above components had been implemented and tested at GMD-IPSI. Examples and initial applications have shown that using the system users can easily define the schemata of many activity spaces and hyper-documents. They can also create new activity spaces with stepwise structure transformation and through reusing existing activity spaces. The system then uses the schema knowledge to maintain the semantic consistency of the activity space instances and to provide users with context-sensitive examples, choices, and explanations."

What kind of hypertext/media technology available and necessary should support organizational memory systems? Panelists will examine the extent to which hypertext/media are appropriate for this task. Targets for organizational memories are, for example, strategic planning, project proposals and management, patents, product design cycle documentation, marketing strategies and in each case the underlying design decision rationales. Although large quantities of information exist in corporate databases, they are not readily accessible, not in an adequate format, often not up-to-date, not well organized for reuse, and not well integrated in the overall work process. This becomes even more of a problem when individuals and teams of an organization are distributed in different locations, work in different time zones, and are often (re)assigned to different tasks in new projects.####Several issues are important, such as capturing, representing, documenting, tracing, and updating corporate information focusing on design decisions and requirements; support for creating and maintaining corporate memories in a cooperative and coordinated fashion in small groups and large organizations, annotation and versioning management, accessing and using corporate memories via support from advanced information retrieval, full text search, case-based reasoning in documentation management. And, last but not least, the psychological and social aspects/implications of organizational memory systems.####[no references]"

Group members can work simultaneously in the same computing environment, use the same set of tools and share a network of hypertext objects. Hyperbase (hypertext database) systems must provide special support for collaborative work, requiring adjustments and extensions to normal concurrency control techniques. Based on the experiences of two collaborative hypertext authoring systems, this paper identifies and discusses six concurrency control requirements that distinguish collaborative hypertext systems from multiuser hypertext systems, Approaches to the major issues (locking, notification control and transaction management) are examined from a supporting technologies point of view. Finally, we discuss how existing hyperbase systems fare with respect to the identified set of requirements.

The Dexter Hypertext Reference Model [Hala90] was used as basis for designing the architecture. The Dexter model provides a general and solid foundation for designing a general hypermedia architecture. It introduces central concepts and proposes a layering of the architecture. However, to handle cooperative work aspects, such as sharing material and cooperative authoring, we have to go beyond the Dexter model concepts. TO deal with such aspects we have extended our implementation of the Dexter concepts with support for long-term transactions, locking and event notification as called for by Halasz [Hala88]. The result is a platform independent architecture for developing cooperative hypermedia systems. The architecture consists of a portable kernel that constitutes an object oriented framework for developing Dexter compliant hypermedia systems. It is a client/server architecture including an object oriented database (OODB) to store the objects implementing the Dexter Storage Layer. We use a general 00DB being co-developed to support long term transactions, flexible locking, and event notification. The transaction and locking mechanism support several modes of cooperation on shared hypermedia materials, and the notification mechanism supports the users in maintaining awareness of each others’ activity, The portable kernel was used to implement the DHM system on two quite different platforms: UNIX/X-windows and Apple Macintosh."

The DHM development framework is based on the Dexter Hypertext Reference Model, which introduces a notion of composite to model editors with complex or multiple types of contents. The original Dexter notion of composites is, however, insufficient to cover structural composites including or referencing other components. Thus the DHM framework has been extended with generic composite classes suited to support structures within the hypermedia network itself. The paper presents and discusses the design of the generic composite classes belonging to the STORAGE and RUNTIME layers of the framework. A central aspect of the design is that the structuring mechanism is a true composite with a collection of components as its contents rather than an atomic component with links to other components as in the classical systems such as NoteCards, Intermedia, and KMS. It is also shown how the powerful generic classes can be used to implement a variety of useful hypermedia concepts such as: hierarchy by inclusion, hierarchy by reference, virtual and computed browsers, TableTops and GuidedTours."

This work explores automatic methods of link construction based on feedback from users collected during browsing. A full-text search engine mediates the linking process. Query terms that distinguish well among documents in the database become candidate anchors; links are mediated by passage-based relevance feedback queries. The newspaper metaphor is used to organize the retrieval results.####VOIR, a software prototype that implements these algorithms has been used to browse a 74,500 node (250MB) database of newspaper articles.

The system models the reader’s knowledge of textual components and uses this model to guide adaptive behavior and give the reader a better sense of how structural elements are unfolding.

Two initial proof of concept applications have been developed to demonstrate these concepts, which we describe. Finally we propose a framework for highly distributed delivery and processing of multicast continuous metadata, as a part of the infrastructure necessary to provide a more complete multimedia environment for hypermedia systems."

The hypermedia objects are stored in an object-oriented database that is accessible on the Web via an ordinary URL. The Dexter-based hypermedia service is based on the Devise Hypermedia framework. Three client solutions are described and discussed, one that is platform independent based on Netscape Navigator 3.0, utilizing Java, JavaScript, and LiveConnect, and two that are platform dependent, one utilizing Netscape plug-ins, and another using Microsoft Internet Explorer 3.0, utilizing mainly ActiveX. The server part is developed as a specialization of the Devise Hypermedia framework accessible through CGI scripts. Thus the system provides the full power of Dexter-based hypermedia to arbitrary Web pages on the Internet. This includes the ability for multiple users to create links from parts of HTML Web pages they do not own and support for creating links to parts of Web pages without writing HTML target tags. Support for providing links to/from parts of non-HTML data, such as Quicktime movies or VRML documents will also be possible in the future provided that appropriate open plug-in modules become available."

To dynamically generate relevant information nodes knowledge about an individual user and his actual task together with intelligent filtering methods can be used. Terms, organized in hierarchies, describe employees, groups of employees, machines, objects, products, processes and functions. Choosing terms specifying the actual task defines a special context which describes the relation and connection of units of information and therefore the user’s individual view of the hypertext. Simultaneously it will be meaningful to look at similar contexts of other users or working groups to compare and possibly add further units of information into the user’s private area. A system can be adaptive in the sense that units of information will be copied into a working group area if more than a certain percentage of its members will regard this information as important and vice versa.

This rich link structure not only creates orientation problems, it may also be a source of comprehension problems when users follow paths through the information which the author did not foresee. Adaptive techniques have been used by a number of researchers [1,2,4,5,6,7,8,9, 10,17,19,20,22] in an attempt to offer guidance through and orientation support for rich link structures. The majority of these adaptive hypermedia systems (AHS) have been used in educational applications. The terminology used in this paper also has an educational “flavor”. However, there are some adaptive on-line information systems (or “kiosk”- systems), adaptive information retrieval systems, and other adaptive hypermedia applications.####In this paper we describe a reference model for adaptive hypermedia applications, called AHAM, which encompasses most features supported by adaptive systems that exist today or that are being developed (and have been published about). Our description of AHS is based on the Dexter model [l-5, 161, a widely used reference model for hypermedia. The description is kept somewhat informal in order to be able to explain AHAM rather than formally specify it. AHAM augments Dexter with features for doing adaptation based on a user model which persists beyond the duration of a session, Key aspects in AHAM are:####- The adaptation is based on a domain model, a user model and a teaching model which consists of pedagogical rules. We give a formal definition of each of these (sub)models (but only describe the pedagogical rules informally through examples).####- l We distinguish the notions of concept, page and fragment. In some AHS these notions are confused.####- We provide a formalism which lets authors write pedagogical rules (about concepts) in such a way that they can be applied automatically.####We illustrate various aspects of AHAM by means of some features of some well-known AHS [6, l0]."

Since (landscape) architects work with 3D objects and environments a natural first step is to design a virtual project room as a 3D virtual environment. The current prototype, Manufaktur, utilizes open hypermedia technology to integrate documents with design models in the virtual project room. Manufaktur provides hot-linking of arbitrary MS Windows documents into the virtual project room, it supports spatial arrangement and categorization of (sub) workspaces by means of proximity, and it provides “classical” open hypermedia linking between segments of documentation. Finally, support for two modes of tightly coupled collaboration in the virtual project room is being provided by means of a session management service. Based on the experiences from design of Manufaktur we discuss design issues for the integration of hypermedia and collaborative virtual environments."

This paper explores the demands our dynamic view of hypertext makes on hypertext standards from two angles. First, what coordination is necessary to establish a dynamic hypertext interface to an arbitrary front-end or back-end information system? Here we introduce the concept of bridge laws to map application components to hypertext structures. Second, how does a dynamic view of hypertext affect document interchange among hypertext systems and between a hypertext and non-hypertext systems?"

The ability to create and follow links with a mere gesture creates a new level of accessibility to hypertext.####Similarly, applications built on PenPoint are exploiting the pen interface for new generations of electronic book technology, in which browsing and search for information can be done without keyboard and mouse, in which annotation can be done with computerized “ink,” and in which remote, wireless connectivity serves as a major new component.####The demonstration will show each of these technologies and explain the fundamental basis behind each of these technologies.####[no references]"

We start by identifying the challenge of hypermedia authoring and production which serves as the driving force for our development. Using interacting problem spaces as the vehicle for modelling the dynamic aspects of authoring, we arrive at a set of requirements answered by the concept of “activity spaces”. The design of coherent hyperdocuments is facilitated by our “construction kit”. Furthermore, we describe the extensions and modifications necessary to support multiple authors with the cooperative version of SEPIA. The central issue of the paper is the system architecture and its implementation. We describe the basis for access to shared hyperdocuments, the activity space browsers, the integration of multimedia functionality (audio, graphics, pictures), and the integration of a video conferencing system."

In the work reported in this paper we address these three problems by combining Hammond and Allinson’s guided tour metaphor and Frisse’s information retrieval techniques to dynamically create guided tours for users in direct response to a user’s query. One of the features of our method is that we take advantage of typing of information links in the hypertext to generate a tour which has a judicious sequencing of nodes rather than a simple presentation of hypertext nodes in order of similarity to the user’s query. Our method was empirically tested on a population of 125 users who generated a total 973 individual tours and all user actions and responses to questions were logged. The results of this evaluation are presented in this paper."

The Dexter Hypertext Reference Model [8] was used as the basis for the design. Though our experiences were generally positive, we found the model constraining in certain ways and underdeveloped in others. For instance, Dexter argues against dangling links, but we found several situations where permitting and supporting dangling links was advisable. In Dexter, the data objects making up a component’s contents are encapsulated in the component; in practice, references to objects stored apart from the hypermedia structure should be allowed. We elaborate Dexter’s notion of composite component to include composites that “contain” other components and composites with structured contents, among others. The paper also includes a critique of Dexter’s notion of link directionality, proposes a distinction between marked and unmarked anchors, and discusses anchoring within a composite."

The features of statecharts relevant to the modeling of hypertext are described. Statecharts for the common features in frame-based and scrolling-based hypertext are given. Then statecharts are used to model the various buttons supported in a real-life production hypertext system, Guide (both the Unix version and the version marketed by Owl International Inc.).

This paper proposes a specific type of composite component, called “collection”. A collection is a container holding several members. Collections can contain other collections (nested collections). Collections can be regarded as sets, but they can also have an inner structure. Collections can be created in several ways: manually, through queries, by operations on other collections, by exploiting links, etc. Collections introduce a navigational pattern, based on their structure, that is different from the standard node&link navigation. If active media are considered, collections allow the design and implementation of complex synchronisation strategies, difficult to obtain otherwise. The paper describes the motivations for using collections, their structure, their navigational capabilities and a number of possible authoring mechanisms. It also examines the interplay between standard navigation and collection navigation, possible synchronization strategies for collections, as well as the requirements for the definition of a runtime support (which could be used to extend the runtime layer of the Dexter Model)."

Thus, information presentation is independent of the current situation. To improve information accessibility we developed a situation-dependent information medium: responsive manuals. A responsive manual consists of a “standard” hypertext-based operational manual and a task description. It monitors the changing situation and based on this is able to point to relevant information. To show the advantages of the responsive manual approach in the domain of power plant operation we implemented the SIROG (situation-related operational guidance) system in close cooperation with Siemans. It covers all parts of an operational manual for accidents in a Siemans nuclear power plant, and is coupled directly to the plant state. The article discusses the basics of the responsive manuals approach and the role of “responsiveness” in SIROG."

It presents a new way of placing windows, or any graphical object delimited by rectangular boundaries, in the context of an existing set of windows. The heart of the technique presented is a particular re-scaling of the display which changes the locations of objects while maintaining their sizes and avoiding object overlapping. This functionality has uses both for authoring and browsing hypertext documents. In particular it enables the display of hierarchically structured information at various levels of detail and complements other visual graph management functions. More generally, the objective is to attenuate the feeling of disorientation users experience when related information obtained through hypertext browsing are stacked upon a display screen. This work suggests extending hypertext systems by enabling users to create well structured information “collages” and to program animated presentations on the basis of browsing through ill or differently structured collections of documents."

The nested context model also defines an abstract and flexible application program interface that captures the idea that different applications may observe the same node in different ways. Finally, the model offers a rich set of operations to explore the double structure of a hyperdocument - that defined by the links and that induced by the nesting of context nodes."

Obviously the task domains of each of these populations vary considerably. Even so, contemporary compositional, rhetorical and literary theory as well as pedagogical practice provide some consistency regarding design requirements and constraints across domains within the writing process.####For instance there is a broad consensus among compositional theorists that implicit or explicit interpretive communities intervene within the writing process ([Becker 86] lJ.,eFevre 87] ). This intervention can range from the scientific writer’s recognition of the formal requirements of technical prose Eazerman 81], to the creative writer’s awareness of culture [Olson 74], to the beginning writer’s awareness that her immediate audience extends beyond the teacher to the classmates with whom she collaborates and who function as her readers. [Joyce 88] In order to accommodate and represent these varied interventions, system design requires an interplay between hierarchical and other organizational structures as well as an annotational capability which crosses these organizational structures at relatively low cost in terms of cognitive overhead or computation.####Another instance of broad consensus among compositional theorists is that some form of tokenizing, information-hiding, or progressive disclosure performs a valuable function for developmental, experienced and professional writers. For developmental writers an awareness that ideas can be tokenized is a critical first step toward development of hierarchical thinking skills, abstraction, and consideration of audience. [Shaughnessy 77] Concrete representations of fuzzy ideational structures are especially important to developmental writers because they know how such representations are used against them (cf., [Shneiderman 83 ]). Likewise journalists, intelligence analysts, planners and legislators constantly filter and organize texts to convey new understanding, formulating coherent stones from incoherent information or reformulating existing structures to convey new perspective.

The goal of this paper is to investigate these issues and identify possible improvements in this area. Our main inspiration is the Xanadu project and the concept of transclusions. This paper proposes an enhanced model to describe and interact with XML inclusions. We identify multiple classes of inclusions and multiple views of multi-source documents. Particular attention is also given to the idea of making inclusions transparent to both users and applications. An engine producing composite documents, with rich information about inclusions, and a viewer for modularized XML documents are presented as well."

When used effectively this practice allows authors to present clearly large amounts of information in a single page. However, while sighted people can visually parse and understand these complex layouts in seconds, current assistive technologies such as screen readers cannot. This puts visually impaired users at a great disadvantage. In order to design better assistive technologies, we conducted a study of how people interpret modular layouts of news and shopping Web pages. The study revealed that when the layout complexity increases, the interpretation process gets longer and the reading gets more varied. Also, before looking at the main content, users first frame the Web page by looking for familiar structural elements that can be used as references and entry points. These elements include navigational bars, search boxes, and ads. This implies that assistive technologies can reduce the time required to frame the pages if they help users identify reference points and entry points."

This poster suggests to treat navigation as an independent dimension by explicitly describing the navigation space in a dedicated navigation language. The language has three major applications: (1) Describing paths through hypertext. Those paths can be used as recommendations or prescriptions that users may or must follow. (2) Building specialized information access paths to cope with specific information needs. (3) Enabling the automation of recurring navigation patterns. All three cases are related by the notion of a path. We introduce an abstraction that captures the idea of a “path through hypertext”, so-called hypertracks, which are concise, quick to author, and easy to communicate (e.g. via e-mail or Web). This poster motivates the navigation language and introduces the concepts behind it (hypertracks, stateful navigation situations, navigation context, navigation actions, navigation history, predicates for conditional navigation, and an event-based processing model). The concrete syntax of the language and its integration into a browser are under development."

A large number and variety of blogs, like personal journals or commentaries, are available for general consumption. However, effective indexes and navigation structures (like the table of content in a book) are not available for blogs. Therefore, it is generally not possible to navigate among entries in a given collection of blog entries in an informed manner. This paper focuses on the segmentation of entries in filter-type [9] blogs, with the aim of using this information for developing hypertext and navigational helps. In particular, we are interested in the analysis of topic development patterns that can provide information about not only the entries themselves, but how these entries develop and relate to each other. The proposed algorithm, CUTS, maps entries into a curve in a way that makes apparent a variety of topic development patterns. We then use curve analysis for automatic segmentation of topics. The resulting base topic segments are classified into different topic development patterns that can be visualized and indexed. Experimental results show that the proposed technique has very good performance in identifying boundaries in text streams, especially filter style blogs, versus existing schemes. Furthermore, compared with other topic segmentation methods, the proposed mechanism highlights not only topic boundaries, but also topic development patterns."

Thereafter, the user guides the learning process in a hyperlinked environment, by selecting a target concept, exploring the associated learning graph, learning pre-requisite concepts, and repeating this process till her learning goal is reached. To measure usefulness and correctness of our approach, we conducted a user study with 25 users using precision and recall measures. Overall, the feedback from users was encouraging.

Preserving user identity in the data set allows us to discover novel properties of Web traffic that directly affect models of hypertext navigation. We find that the popularity of Web sites—the number of users who contribute to their traffic—lacks any intrinsic mean and may be unbounded. Further, many aspects of the browsing behavior of individual users can be approximated by log-normal distributions even though their aggregate behavior is scale-free. Finally, we show that users’ click streams cannot be cleanly segmented into sessions using timeouts, affecting any attempt to model hypertext navigation using statistics of individual sessions. We propose a strictly logical definition of sessions based on browsing activity as revealed by referrer URLs; a user may have several active sessions in their click stream at any one time. We demonstrate that applying a timeout to these logical sessions affects their statistics to a lesser extent than a purely timeout-based mechanism."

The framework is structured into four levels of signification and allows the designer to control the semantic coherence and optimize the communication during the hypermedia development. We investigate its practical feasibility by constructing an instructional hypermedia regarding a collection of ancient mosaics from a roman villa. Our results indicate that the proposed approach opens novel perspectives, and looks promising towards the definition of semiotic methodologies of hypermedia design."

This problem becomes even worse with the advent of wikis, blogs, forums, which are rich in links. We tackle the problem of improving link-based ranking by more fundamental viewpoint—“noisy link” analysis. Motivated by how “non-voting” hyperlinks affect quality of ranking, we propose an approach and corresponding penalty strategies to both detect and handle “noisy link” effectively and automatically. We also compared our approach with other related works to demonstrate that our approach is rather effective in noisy link filtering and could improve the final search results significantly."

However despite this very little work has been undertaken to understand of take advantage of these themes, particularly in narrative generation where the presence of well defined themes may improve the richness of those generated narratives. In this paper we evaluate the performance of a system utilising a thematic model in order to generate simple narratives in the form of photo montages compared to a keyword based system that does not. The experiment demonstrates that the system utilising the thematic model is capable of successfully connoting themes within these narratives. It also shows that the relevance of the resulting narratives to the titles used to generate them is higher in the thematic system than those generated by the other system."

This paper constructs intra-city travel itineraries automatically by tapping a latent source reflecting geo-temporal breadcrumbs left by millions of tourists. For example, the popular rich media sharing site, Flickr, allows photos to be stamped by the time of when they were taken and be mapped to Points Of Interests (POIs) by geographical (i.e. latitude-longitude) and semantic (e.g., tags) metadata.####Leveraging this information, we construct itineraries following a two-step approach. Given a city, we first extract photo streams of individual users. Each photo stream provides estimates on where the user was, how long he stayed at each place, and what was the transit time between places. In the second step, we aggregate all user photo streams into a POI graph. Itineraries are then automatically constructed from the graph based on the popularity of the POIs and subject to the user’s time and destination constraints.####We evaluate our approach by constructing itineraries for several major cities and comparing them, through a “crowd-sourcing” marketplace (Amazon Mechanical Turk), against itineraries constructed from popular bus tours that are professionally generated. Our extensive survey-based user studies over about 450 workers on AMT indicate that high quality itineraries can be automatically constructed from Flickr data."

Researchers are exploring the use of these annotations to create implicit links between online resources. We define an implicit link as a relationship between two online resources established by the Web community. An individual may create or reinforce a relationship between two resources by applying a common tag or organizing them in a common folder. This has led to the exploration of techniques for building networks of resources, categories, and people using the social annotations. In order for these techniques to move from the lab to the real world, efficient building and maintenance of these potentially large networks remains a major obstacle. Methods for assembling and indexing these large networks will allow researchers to run more rigorous assessments of their proposed techniques. Toward this goal we explore an approach from the sparse matrix literature and apply it to our system, GiveALink.org. We also investigate distributing the assembly, allowing us to grow the network with the body of resources, annotations, and users. Dividing the network is effective for assembling a global network where the implicit links are dependent on global properties. Additionally, we explore alternative implicit link measures that remove global dependencies and thus allow for the global network to be assembled incrementally, as each participant makes independent contributions. Finally we evaluate three scalable similarity measures, two of which require a revision of the data model underlying our social annotations."

In online question and answer forums, hyperlinks record a fleeting social interaction, an information exchange. In other instances, for example, in virtual worlds, social hyperlinks may be conduits for social influence, direct transfer of information, or even the sharing of virtual goods. Occasionally, an online tie is established in order to navigate the real world, or more specifically, find a real couch to sleep on.

This strategy is optimal for the given model of the interaction and it is adapted to the users’ behaviors. In this paper we validate our approach in an online CRS by means of a user study involving several hundreds of testers. We show that the optimal strategy is different from the fixed one, and supports more effective and efficient interaction sessions."

Although Newman-Girvan modularity is popular for unipartite networks, it is not suitable for n-partite networks. For bipartite networks, Barber, Guimera, Murata and Suzuki define bipartite modularities. For tripartite networks, Neubauer defines tripartite modularity which extends Murata’s bipartite modularity. However, Neubauer’s tripartite modularity still uses projections and it will lose information that original tripartite networks have.

In contrast, this paper examines the accuracy of predicting a user’s next action based on analysis of the content of the pages requested recently by the user. Predictions are made using the similarity of a model of the user’s interest to the text in and around the hypertext anchors of recently requested Web pages. This approach can make predictions of actions that have never been taken by the user and potentially make predictions that reflect current user interests. We evaluate this technique using data from a full-content log of Web activity and find that textual similarity-based predictions outperform simpler approaches."

As textual content of Web documents is often scarce or irrelevant and existing summarization techniques are based on it, many Web pages and websites cannot be suitably summarized. We consider the context of a Web document by the textual content of all the documents linking to it. To summarize a target Web document, a context-based summarizer has to perform a preprocessing task, during which it will be decided which pieces of information in the source documents are relevant to the content of the target. Then a context-based summarizer faces two issues: first, the selected elements may partially deal with the topic of the target, second they may be related to the target and yet not contain any clues about the content of the target. In this paper we put forward two new summarization by context algorithms. The first one uses both the content and the context of the document and the second one is based only on the elements of the context. It is shown that summaries taking into account the context are usually much more relevant than those made only from the content of the target document. Optimal conditions of the proposed algorithms with respect to the sizes of the content and the context of the document to summarize are studied."

Seven dimensions of interactive communication that delineate a design space for the area are described. Previous work and existing new media are used to initially populate the design space and show opportunities for new research directions. VKB spaces, Synchrony PADLs, and Walden’s paths are used as foils for describing new media for interactive scholarly communication. This leads to a brief discussion of uncovered areas in the design space and open research questions. A community developed framework for future interactive scholarly communications would be a major contribution and is put forth as the overall goal."

This is especially the case when a hypertext anchor is inaccurately described or is described out of context as confusion and disorientation can ensue. Mobility is similarly reduced when the link target of the anchor has no relationship to the expected information present on the hypertext node (Web page). Confident movement with purpose, ease, and accuracy can only be achieved when complete contextual information and an accurate description of the proposed destination (preview) are available. We suggest that sighted people can benefit from additional context and preview information included in hyperlinks and disprove the empirical evidence that suggests these users do not benefit from link descriptions which have this enhanced information. We briefly describe a middleware system to automatically expand context and preview in link descriptions thereby ‘fixing’ terse links, links out of context, and inaccurate or inadequate preview information. Finally, we conduct a formative evaluation which shows us that a system to expand context and preview would be useful in different ways depending on the type of link. collapse"

XLink improves on HTML’s linking capabilities in several ways. In particular, links after XLink can be “out-of-line” (i.e., not defined at a link source) and collected in (possibly several) linkbases, which considerably ease building complex link structures. Regarding its architecture as a distributed and open system, the Web differs significantly from traditional hypermedia systems. Modeling of link structures and processing of linkbases under the Web’s “open world linking” require rethinking the traditional approaches. This, unfortunately, has been rather neglected in the design of XLink. Adding a notion of “interface” to XLink, as suggested in this work, can considerably improve modeling of link structures. When a link structure is traversed, the relevant linkbase(s) might become ambiguous. We suggest three linkbase management modes governing the binding of a linkbase to a document to resolve this ambiguity."

Collaborative hypermedia systems and standards like BSCW, Wikis, and WebDAV enable people to establish formal and informal collaboration patterns across the Internet. The easy to use Blog/Weblog systems have made it possible for people to establish communities, express opinions, and spark debates over the Internet with minimal effort. Open hypermedia and annotation systems have been developed to support linking and commenting on existing Web documents to support scholarly discourse of online material. Many e-learning applications have been built on top of these systems to provide support for remote learning activities in schools and at workplaces. However, this focus on remote and distributed social networks has to some degree taken the focus away from social networks and collaboration among people who share the same physical environment whether face-to-face or over time. Physical environments in this context may be public spaces or buildings such as workplaces, schools, libraries, museums, and homes. Some of the technologies listed above may of course be applied by people who are in close proximity to each other who shares the same space over time, but I will argue that there is a need to focus on and conduct research in new ubiquitous hypermedia infrastructures and interaction techniques to also support social interaction and networking among people who share the same physical environment. In the Center for Interactive Spaces and predecessor projects, we have focused on the development of various kinds of ubiquitous hypermedia infrastructures and applications that support collaboration or social interaction among proximate peers at work, at school, at libraries, at museums, etc. We are applying various augmented reality tagging mechanisms (e.g., geo-tags, RFID, Bluetags, and visual tags) to provide hypermedia links among digital resources, people, objects and places. We are applying various mobile, spatial, and multi-user interaction techniques to provide new types of interfaces for social interaction in physical spaces. In the Center for Interactive Spaces we have developed several examples of ubiquitous hypermedia applications: eBag—an electronic schoolbag system with seamless login based on bluetooth ID; iFloor—an interactive floor for libraries and schools providing hypermedia functionality for collective search, exploration, debate, and knowledge sharing; InfoGallery—an exhibition system for digital resources and debates at libraries, museums, attractions, and cityscapes; HyConExplorer utilizing geo- and RFID-tagging to annotate the outdoor environment for school projects or the like.

A browser built using this framework would be a client-side system that downloads, in real time, past page versions from Web archives for their customized presentation. It would use passive browsing, change detection and change animation to provide a smooth and satisfactory browsing experience. We propose a meta-archive approach for increasing the coverage of past Web pages and for providing a unified interface to the past Web. Finally, we introduce query-based and localized approaches for filtered browsing that enhance and speed up browsing and information retrieval from Web archives."

Its development started in 1996. During 10 years of research and development different new presentation, adaptation and user modeling methods and techniques have been added, turning AHA! into a general-purpose adaptive hypermedia platform. This paper presents an overview of the design and architecture of AHA!, with parts that have been published before and with recent additions like style adaptation and a new very flexible link annotation mechanism. Unlike other adaptive hypermedia systems, AHA! is not aimed at a single application area and does not prescribe a single fixed presentation style. Creating applications, defining the user models and the adaptive behavior are all done using graphical authoring tools. End-users are presented with what looks like a normal website, and need not be aware of the adaptation that goes on behind the scenes. Their browsing results in updates to a user model that is stored either in an xml file or a mySQL database, and that is thus also (in principle) available to other applications. Apart from providing a design overview this paper highlights two essential parts of AHA!: the reasoning / rule engine that translates the end-user’s actions into user model updates, and the adaptive resource selection, which is used in the conditional inclusion of objects presentation technique and in the conditional link destinations navigation support technique. This paper is itself an adaptive hyperdocument. The order in which the different topics are visited determines the links that are presented and the contents of each (web)page. No matter how you browse through this paper you should end up with a very similar overall impression, and you should have seen all the information the paper contains. However, the actual contents of the pages and the actual link destinations do depend on your browsing order, so different users will not see exactly the same pages and links. Although strictly speaking this paper could be presented using normal linear text, making it an adaptive hyperdocument transforms it from being “just” a paper into being a paper and a demo all in one.####ahadesign.zip (255.4 KB)####As of this publication, the paper is up and running on http://aha.win.tue.nl:18080/aha/ahadesign/ The zip file contains the “ahadesign.gaf” file with the conceptual structure and the “ahadesign” directory with the paper content.

This process raises important questions both for artists and for hypertext theorists. What is the place of verbal forms in a context of dynamic images? How can the spatial agenda of hypertext navigation be reconciled with animation, simulation, and other primarily temporal techniques? What can creators of hypertext systems learn from aesthetic encounters between word and image.####[no references]"

That is, decisions regarding representations of structures in structural computing architectures based upon atoms cannot be recast at run-time. In this paper, we examine an alternative to atom-based models for structural computing systems that allows exactly such recasting. We demonstrate how this alternative model, which we call EAD, is superior to atom-based models for certain important applications, and describe our initial prototypical implementations."

Open hypermedia had produced software that provided applications with access to hypermedia structures and services. The question was asked if these results could be generalized to create similar tools for other domains. Initial work focused on the development of structure servers that can create and manipulate domain-specific structures, but little work focused on allowing those structures to provide a rich set of behaviors. Indeed, this forced developers to place behaviors on the client rather than having behaviors live within a structure server. This paper presents research on the addition of a type system to the Themis structure server and how these types interact with Themis’s template mechanism to provide a single interface that unifies structure, behavior, and data. This new mechanism lets behaviors live within a structure server allowing them to be shared by client applications. To demonstrate its power, Themis is being used to re-implement the Chimera open hypermedia system."

In this paper we re-propose an old paradigm for writing content on the net, directly derived from the Xanadu vision by Ted Nelson: global editability foresees that all documents on the web can be accessed for editing and modified on line, very much as in a global wiki. Global editability needs to address a number of issues, including correct support for intellectual property and legal issues, before it can be accepted as an idea. We provide some considerations on technical issues of global editability, and describe the architecture and implementation of a system, called IsaWiki, that is being developed at the University of Bologna."

This could not be more wrong and more misleading. Indeed, at least for the next couple of decades, the futures are hybrid in all aspects and in practically all domains. For example, we are still far away from an educational system that operates only in virtual worlds. Friends’ circles in social networking sites turn out to serve primarily the sustainability of existing real world friendships. While simulations and software (virtual instrument) solutions were trendy during the last few decades, we now witness a rapid development in robotics. Flying (i.e., drones), ground robots (i.e., robot dogs), and microcontrollers, fully equipped with sensors and actuators are about to massively populate every natural or man-made environment. This talk will discuss how underlying principles of hybrid futures evade and dictate developments in every aspect of IT, ranging from education and HCI, to visualizations and digital humanities, all grounded in the intelligent linking between software algorithms and physical infrastructures. The implications for the Anthropocene will be highlighted and discussed.####[no references]"

In our analysis of datasets from two different social networks, Facebook and Twitter, we find that a small percentage of active users and much less of all users represent 50% of the UGC. We also analyze the dynamic behavior of the generation of this content to find that the set of most active users is quite stable in time. Moreover, we study the social graph, finding that those active users area a highly connected among them. This implies that most of the wisdom comes from a few users challenging the independence assumption needed to have a wisdom of crowds. We also address the content that is never seen by any people (the digital desert), which challenges the assumption that the content of every person should be taken in account in the collective decision.

The large number of datasets demands a new generation of Smarter Systems for data content aggregation that allows users to incrementally liberate, access and integrate information, in a manner that scales in terms of gain for the effort spent. In the context of such a pay-as-you go system, we are presenting a novel method for exploring and discovering relevant datasets based on semantic relatedness. We are demonstrating a system for contextual knowledge mining on hundreds of real-world datasets from Dublin City. We evaluate our semantic approach, using query logs and domain expert judgments, to show that our approach effectively identifies related datasets and outperforms text-based recommendations."

Here we focus on Instagram, a media-sharing online platform whose popularity has been rising up to gathering hundred millions users. Instagram exhibits a mixture of features including social structure, social tagging and media sharing. The network of social interactions among users models various dynamics including follower/followee relations and users’ communication by means of posts/comments. Users can upload and tag media such as photos and pictures, and they can “like” and comment each piece of information on the platform. In this work we investigate three major aspects on our Instagram dataset: (i) the structural characteristics of its network of heterogeneous interactions, to unveil the emergence of self organization and topically-induced community structure; (ii) the dynamics of content production and consumption, to understand how global trends and popular users emerge; (iii) the behavior of users labeling media with tags, to determine how they devote their attention and to explore the variety of their topical interests.####Our analysis provides clues to understand human behavior dynamics on socio-technical systems, specifically users and content popularity, the mechanisms of users’ interactions in online environments and how collective trends emerge from individuals’ topical interests."

We study this interplay of language and network structure in diverse, multi-lingual societies, using Twitter. In our analysis, we are particularly interested in the role of bilinguals. Concretely, we attempt to quantify the degree to which users are the “bridge-builders” between monolingual language groups, while monolingual users cluster together. Also, with the revalidation of English as a lingua franca on Twitter, we reveal users of the native non-English language have higher influence than English users, and the language convergence pattern is consistent across the regions. Furthermore, we explore for which topics these users prefer their native language rather than English. To the best of our knowledge, this is the largest sociolinguistic study in a network setting."

Analysis of media bias has a long tradition in political science.

We also seek to find where the Semantic Web has failed and succeeded, illustrated by usage in web search, e-commerce and online media. Further, we will attempt to understand whether it makes sense to pursue at least some of these ideas in a different age, with new opportunities brought about by recent developments in Big Data, cloud computing, and Deep Learning.####[no references]"

Consequently, in these platforms anyone can publish content and anyone interested in the content can obtain it, representing a transformative revolution in our society. However, this same potential of social media systems brings together an important challenge—these systems provide space for discourses that are harmful to certain groups of people. This challenge manifests itself with a number of variations, including bullying, offensive content, and hate speech. Specifically, authorities of many countries today are rapidly recognizing hate speech as a serious problem, specially because it is hard to create barriers on the Internet to prevent the dissemination of hate across countries or minorities. In this paper, we provide the first of a kind systematic large scale measurement and analysis study of hate speech in online social media. We aim to understand the abundance of hate speech in online social media, the most common hate expressions, the effect of anonymity on hate speech and the most hated groups across regions. In order to achieve our objectives, we gather traces from two social media systems: Whisper and Twitter. We then develop and validate a methodology to identify hate speech on both of these systems. Our results identify hate speech forms and unveil a set of important patterns, providing not only a broader understanding of online hate speech, but also offering directions for detection and prevention approaches."

In this paper, we focus on problem (i) based on a distinction between two types of user motivations that we have identified in earlier work: Categorizers vs. Describers. To that end, we systematically define and evaluate a number of measures designed to discriminate between describers, i.e. users who use tags for describing resources as opposed to categorizers, i.e. users who use tags for categorizing resources. Subsequently, we present empirical findings from qualitative and quantitative evaluations of the measures on real world tagging behavior. In addition, we conducted a recommender evaluation in which we study the effectiveness of each of the presented measures and found the measure based on the tag content to be the most accurate in predicting the user behavior closely followed by a content independent measure. The overall contribution of this paper is the presentation of empirical evidence that tagging motivation can be approximated with simple statistical measures. Our research is relevant for (a) designers of tagging systems aiming to better understand the motivations of their users and (b) researchers interested in studying the effects of users’ tagging motivation on the properties of resulting tags and emergent structures in social tagging systems"

Their success is due to their freedom and simplicity of use. To post a resource, the user should only define a set of tags that would position the resource in the system’s data structure—folksonomy. This data structure can serve as a rich source of information about relations between tags and concepts they represent. To make use of information collaboratively added to folksonomies, we need to understand how users make tagging decisions. Three factors that are believed to influence user tagging decisions are: the tags used by other users, the organization of user’s personal repository and the knowledge model shared between users. In our work we examine the role of another potential factor—resource title. Despite all the advantages of tags, tagging is a tedious process. To minimize the effort, users are likely to tag with keywords that are easily available. We show that resource title, as a source of useful tags, is easy to access and comprehend. Given a choice of two tags with the same meaning, users are likely to be influenced by their presence in the title. However, a factor that seems to have stronger impact on users’ tagging decisions is maintaining the consistency of the personal profile of tags. The results of our study reveal a new, less idealistic picture of collaborative tagging systems, in which the collaborative aspect seems to be less important than personal gains and convenience."

To support comprehension of the history, we describe automatic history clustering to group low-level system events into a more human-level representation of activity and the extraction of information for summarizing these groups of events. To further support navigation and comprehension of history, the mechanism includes multiple visualization techniques to match diverse uses of history.

In contrast to existing approaches, which analyze documents’ words but ignore their citations, this approach is based on citation analysis and allows duplicate and plagiarism detection even if a document has been paraphrased or translated, since the relative position of citations remains similar. Although this approach allows in many cases the detection of plagiarized work that could not be detected automatically with the traditional approaches, it should be considered as an extension rather than a substitute. Whereas the known text analysis methods can detect copied or, to a certain degree, modified passages, the proposed approach requires longer passages with at least two citations in order to create a digital fingerprint."

This can have a particular impact when the contextualization is used in the process of assessing student learning. This study investigates the types of words that cause difficulty for students. The assessment shows that there are terms used on engineering tests that present possible barriers for students, such that the test may in part be assessing the student’s cultural knowledge or vocabulary rather than engineering competency. We propose a number of strategies for remediating this situation including the use of hypertext to mitigate this type of accessibility barrier."

To extract user interests, the method first extracts candidate keyphrases from the user’s web browsed documents. Second, important keyphrases obtained from a link structure analysis of Wikipedia content is extracted from the main contents of web documents. This technique is based on the idea that important keyphrases in Wikipedia are important keyphrases in the real world. Finally, keyphrases contained in the documents important to the user are set in order as user interests. An experiment shows that our method offers improvements over a conventional method and can recommend interests attractive to the user."

The scalability of this approach allows us to study the English Wikipedia community as a co-authorship network. We find evidence of the presence of a nucleus of very active contributors, who seem to spread over the whole wiki, and to interact preferentially with inexperienced users. The fundamental role played by this elite is witnessed by the growing centrality of sociometric stars in the network. Isolating the community active around a category, it is possible to study its specific dynamics and most influential authors."

We have developed VITE to allow users to interact with information in a semi-formal workspace. Creating two-way mapping profiles is a vital step for projecting structured information into a spatial hypermedia system. A previous study of VITE indicated that users spent much of their time developing an initial mapping before working on the information task. We designed the Mapping Assistant to assist users by generating a quick initial mapping from the data entered by the user and reduce the cognitive and mental load on the user. This research studies users’ impression of the Mapping Assistant.

These tags are distinct from those in other Web 2.0 systems because users are less likely to index messages for later retrieval. We compare tagging patterns in Twitter with those in Delicious to show that tagging behavior in Twitter is different because of its conversational, rather than organizational nature. We use a mixed method of statistical analysis and an interpretive approach to study the phenomenon. We find that tagging in Twitter is more about filtering and directing content so that it appears in certain streams. The most illustrative example of how tagging in Twitter differs is the phenomenon of the Twitter micro-meme: emergent topics for which a tag is created, used widely for a few days, then disappears. We describe the micro-meme phenomenon and discuss the importance of this new tagging practice for the larger real-time search context."

Surprisingly, implicit evidences (like click logs) of user relations have hardly been considered to this end.####Based on our long-time experience with running BibSonomy [4], we identify in this paper different evidence networks of user relationships in our system. We broadly classify each network based on whether the links are explicitly established by the users (e.g., friendship or group membership) or accrue implicitly in the running system (e.g., when user u copies an entry of user v).

Two related studies were carried out, the first where domain experts and others tagged videos, and the second where experts and others rated the relevance of tags that had been assigned to videos in the first study. Expert tags were judged to be more relevant by both experts and non-experts, with non-expert viewers also creating significantly better tags than did owners (i.e., the people who uploaded the videos). While significant differences were observed, the mean overall judged relevance of tags was relatively low, even for experts.

However, traditionally such systems have focussed on mainly corporate or professionally authored content and have not been able to leverage the benefits of other material already on the web, written about that subject by other authors. Such information includes open-web information as well as user-generated content such as forums, blogs, tags, etc. By providing personalized compositions and presentations across these heterogeneous information sources, a potentially richer user experience can be created, leveraging the mutual benefits of professionally authored content as well as open-web information and active user communities. This paper presents novel techniques and architectures that extend the personalization reserved for corporate or professionally developed content with that of user generated content and pages in the wild. Complementary affordances of Personalized Information Retrieval and Adaptive Hypermedia are leveraged in order to provide Adaptive Retrieval and Composition of Heterogeneous INformation sources for personalized hypertext Generation (ARCHING). The approach enables adaptive selection and navigation according to multiple adaptation dimensions and across a variety of heterogeneous data sources.

The evidence clearly shows that the system successfully blends a user’s search experience with adaptive selection and navigation techniques and that the user experience is improved in terms of both task assistance and user satisfaction."

Four groups, consisting of 3 members each, were asked to use ShyWiki for creating, sharing and brainstorming knowledge during the design and documentation of a software architecture. We present the evaluation of a questionnaire that users answered about their perceived usefulness and easiness of use of the spatial and visual properties of ShyWiki, and several of its features.

We use this methodology for evaluating how tag recommendations coming from (1) the popular tags at a resource or from (2) the user’s own vocabulary influence the indexing quality. We show that recommending popular tags decreases the indexing quality and that recommending the user’s own vocabulary increases the indexing quality."

These authorial decisions can produce different dramatic effects. Storyspace is a web interface to an ontology for describing curatorial narratives. We describe how the narrative component of the Storyspace software can produce multiple narratives from the underlying stories and plots of curated exhibitions. Based on the curator’s choice, the narrative module suggests a coherent ordering for the events of a story and its associated heritage objects. Narratives constructed through Storyspace can be tailored to suit different audiences and can be presented in different forms, such as physical exhibitions, museum tours, leaflets and catalogues, or as online experiences."

While comparing information from multiple sources provides a foundation for such awareness, keeping pace with everything being written is a daunting proposition, especially for the casual reader. We propose a new form of technological assistance for critical literacy which automatically discovers and displays underlying memes: ideas represented by similar phrases which occur across different information sources. By surfacing these memes to users, we create a rich hypertext representation in which underlying memes can be explored in context. Given the vast scale of social media, we describe a highly-scalable system architecture designed for MapReduce distributed computing. To validate our approach, we report on use of our system to discover and browse memes in a 1.5 TB collection of crawled social media. Our primary contributions include: 1) a novel technological approach and hypertext browsing design for supporting critical literacy; and 2) a highly-scalable system architecture for meme discovery, providing a solid foundation for further system extensions and refinements."

A major approach for assessing articles using edit history is a text survival ratio based approach. However, the problem is that many high-quality articles are identified as low quality, because many vandals delete high-quality texts, then the survival ratios of high-quality texts are decreased by vandals. Our approach’s strongest point is its resistance to vandalism. Using our method, if we calculate text quality values using editor quality values, vandals do not affect any quality values of the other editors, then the accuracy of text quality values should improve. However, the problem is that editor quality values are calculated by text quality values, and text quality values are calculated by editor quality values. To solve this problem, we mutually calculate editor and text quality values until they converge. Using this method, we can calculate a quality value of a text that takes into consideration that of its editors."

Despite this there is little understanding of how these applications are related or how they link with existing hypertext models and theory.####We argue that location aware narrative systems tend to follow three patterns (canyons, deltas and plains) and that it is possible to represent all of these patterns in a conceptual sculptural hypertext model. Our model builds on a general sculptural mechansim (of pre-conditions and behaviours) to include locality and narrative transitions as first class elements, opening the possibility of standardised viewers, formats, and hybrid stories. We show how existing structures can be mapped onto this conceptual sculptural model, and how narratives defined in the model can take advantage of open data sources and sensed contextual data. To demonstrate this we present the GeoYarn system, a prototype which implements the model to create interactive, location aware narratives, using all three patterns."

In LBSNs, users can check in and leave tips commenting on a venue. These two heterogeneous data sources both describe users’ preference of venues. However, in current research work, only users’ check-in behavior is considered in users’ location preference model, users’ tips on venues are seldom investigated yet. Moreover, while existing work mainly considers social influence in recommendation, we argue that considering venue similarity can further improve the recommendation performance. In this research, we ameliorate location recommendation by enhancing not only the user location preference model but also recommendation algorithm. First, we propose a hybrid user location preference model by combining the preference extracted from check-ins and text-based tips which are processed using sentiment analysis techniques. Second, we develop a location based social matrix factorization algorithm that takes both user social influence and venue similarity influence into account in location recommendation. Using two datasets extracted from the location based social networks Foursquare, experiment results demonstrate that the proposed hybrid preference model can better characterize user preference by maintaining the preference consistency, and the proposed algorithm outperforms the state-of-the-art methods."

Apart from few exceptions, poetics of the link overshadows poetics of the node. My goal is to re-focus on a single node, or lexia, by introducing the concept of contextual regulation as the major force that shapes hypertext narrative units. Because many lexias must be capable of occurring in different contexts and at different stages of the unfolding story, several compromises have to be made on the level of language, style, plot and discourse. Each node, depending on its position and importance, has a varying level of connectivity and autonomy, which affects the global coherence of text.####After focusing on relations between the notion of lexia (as a coherent and flexible unit) and the notion of kernel in narrative theory, an explanation of rules behind contextual regulation is presented, along with the basic typology of nodes. Then an attempt to enhance existing plot pools for hypertext fiction is undertaken. Several suggestions for the new plots, offered by the node-centered approach, are introduced."

However, this can require large volumes of content, with appropriate granularities and suitable meta-data descriptions. This represents a major impediment to the mainstream adoption of Adaptive Hypermedia. Open Adaptive Hypermedia systems have addressed this challenge by leveraging open corpus content available on the World Wide Web. However, the full reuse potential of such content is yet to be leveraged. Open corpus content is today still mainly available as only one-size-fits-all document-level information objects. Automatically customizing and right-fitting open corpus content with the aim of improving its amenability to reuse would enable AHS to more effectively utilise these resources.####This paper presents a novel architecture and service called Slicepedia, which processes open corpus resources for reuse within AHS. The aim of this service is to improve the reuse of open corpus content by right-fitting it to the specific content requirements of individual systems. Complementary techniques from Information Retrieval, Content Fragmentation, Information Extraction and Semantic Web are leveraged to convert the original resources into information objects called slices. The service has been applied in an authentic language elearning scenario to validate the quality of the slicing and reuse. A user trial, involving language learners, was also conducted. The evidence clearly shows that the reuse of open corpus content in AHS is improved by this approach, with minimal decrease in the quality of the original content harvested."

In the literature, this distinction has been described as a distinction between broad vs. narrow folksonomies. This paper sets out to explore navigational differences between broad and narrow folksonomies in social hypertextual systems. We study both kinds of folksonomies on a dataset provided by Mendeley - a collaborative platform where users can annotate and organize scientific articles with tags. Our experiments suggest that broad folksonomies are more useful for navigation, and that the collaborative processes that are generating folksonomies matter qualitatively. Our findings are relevant for system designers and engineers aiming to improve the navigability of social tagging systems."

We propose to address the case of mixed interests’ exploration in the form of composite queries (several unitary interests combined) e.g. exploring results and make discoveries related to both The Beatles and Ken Loach.. The main contribution of this paper is the proposition of a novel method that processes linked-data for exploratory search purpose. It makes use of a semantic spreading activation algorithm coupled with a sampling technique. Its particularity is to not require any results preprocessing. Consequently this method offers a high level of flexibility for querying and allows, among others, the expression of composite interests’ queries on remote linked data sources. This paper also details the analysis of the algorithm behavior over DBpedia and describes an implementation: the Discovery Hub application. It is an exploratory search engine that notably supports composite queries. Finally the results of a user evaluation are presented."

We apply several variations of decentralized search to model human navigation in information networks and we evaluate the outcome in a series of experiments. In these experiments, we study the validity of decentralized search by comparing it with human navigational paths from an actual information network - Wikipedia. We find that (i) navigation in social networks appears to differ from human navigation in information networks in interesting ways and (ii) in order to apply decentralized search to information networks, stochastic adaptations are required. Our work illuminates a way towards using decentralized search as a valid model for human navigation in information networks in future work. Our results are relevant for scientists who are interested in modeling human behavior in information networks and for engineers who are interested in using models and simulations of human behavior to improve on structural or user interface aspects of hypertextual systems."

Identifying such behaviour requires a deep understaning on how people interact via OSNs during political debates. We present a preliminary study of interactions in a popular OSN, namely Instagram.

We record their posts for more than two months, tracking “likes” and comments from users. Results suggest that profiles of politicians attract markedly different interactions than other categories.

Moreover, comments tend to come from a small group of very active users. Finally, we witness substantial differences when comparing profiles of different parties."

The poster presents experiments for an approach towards visual historiography to support historical understanding. A case study from historical sociology demonstrates the added value of diagrammatic representation of causal narratives. The advantage of using diagrams with a hypertextual approach is that idiographic details can still be communicated through textual information in the hypertext nodes due to multimodal combination of diagram and written language. I suggest a semantic wiki with suitable domain ontologies as a tool for structured writing—i.e. modeling—of causal processes as described in causal narratives. As the approach enables the (re)presentation of history as diagram by means of diagrammatic reasoning according to Peircean semiotics I propose the label diagrammatic hypertext."

We consider user-level as well as tweet-level meta-data features, and identify patterns and correlations of these feature with the log-odds for sentiment classes. We further strengthen our analysis by replicating this set of experiments on recent tweets from users present in our datasets; finding that most of the patterns are consistent across our analysis. Finally, we use our identified meta-data features as features for a sentiment classification algorithm, which results in around 2% increase in F1 score for sentiment classification, compared to text-only classifiers, along with a significant drop in KL-divergence. These results have potential to improve sentiment analysis applications on social media data."

Online communities draw various individuals together based on their common opinions on a core set of issues. Most existing community detection methods merely focus on discovering communities without providing any insight regarding the collective opinions of community members and the motives behind the formation of communities. Several efforts have been made to tackle this problem by presenting a set of keywords as a community profile. However, they neglect the positions of community members towards keywords, which play an important role for understanding communities in the highly polarized atmosphere of social media. To this end, we present a sentiment-driven community profiling and detection framework which aims to provide community profiles presenting positive and negative collective opinions of community members separately. With this regard, our framework initially extracts key expressions in users’ messages as representative of issues and then identifies users’ positive/negative attitudes towards these key expressions. Next, it uncovers a low-dimensional latent space in order to cluster users according to their opinions and social interactions (i.e., retweets). We demonstrate the effectiveness of our framework through quantitative and qualitative evaluations."

On closer analysis, however, theorizing just what this entails has remained limited. Similarly to the situation that long held concerning 'written' texts, it is too easily assumed that different modalities, sometimes labelled with terms such as 'text' or 'image', combine 'naturally' and so users should be able to follow such combinations with relative ease. Research on literacy, particularly with respect to contemporary media configurations, has shown this assumption to be false.####Constructing coherent interpretations of combinations of modalities can be far from straightforward, even when supported by good interface design; with poor design, which from the perspective of displayed 'documents' is unfortunately rather common, finding intended interpretations can present significant challenges. Now, when translated to the even more complex medial environment of hypertext, these potential problems are magnified considerably. Moreover, traditional considerations of where the 'boundaries' of hypertext might lie are now being redrawn as hypertext and the increasingly 'hyper'-connected medial world become increasingly permeable. The entire multimodal world of social media and participatory digital cultures might then be considered from a hypertext perspective, but research on hypertext itself lacks conceptual tools with the power necessary to engage with that world. Simple 'extensions' of traditional notions of hypertext are likely to prove insufficient for a full-blown account of multimodality.####In this talk we address these concerns from the perspective of current developments in multimodality studies, where the starting point is communication as such, regardless of the expressive forms that are used for that communication and whether communication is mediated computationally, via interlinked artefacts and pathways, or by cross-linked practices of digital and non-digital use. In short, current medial practices demand that hypertext be seen not simply as, for example, a shift from page-based documents to video, but as a further computationally supported environment for the development and deployment of core multimodal theoretical constructs such as semiotic modes, media and genres. We introduce these concepts and show several practical examples of processing from ongoing projects with a variety of media."

The claim is more plausible technically than culturally, but the talk is perversely addressed to culture. Among other things, the discussion revisits Moulthrop’s previous ACM Hypertext keynote in 1998, in which he distinguished between “exoteric” hypertext - the then-novel adaptation of the World Wide Web by Amazon and other online retailers - and “esoteric” applications in things like hypertext fiction and digital art. The talk updates this insight with reference to later developments such as Jill Walker’s “feral hypertext” thesis, the rise of social media, and the recognition of computer games as legitimate channels of ideas.####While these phenomena have arguably displaced hypertextuality in the popular imagination, Moulthrop points to the major interest in complex narratives, counterfactuals, and multiverses as places where the hypertext aesthetic survives. Turning from aesthetics back to the technical, the talk focuses on Twine, the popular text-gaming application that marries what Alexander Galloway would call the “proctological” openness of web technologies with the structure-mapping affordances of graphical hypertext systems. In some ways portraying Twine as a second coming of hypertext is a clear and perhaps intentional misreading. The talk ends by wondering what this misreading might reveal.####[no references]"

Readers go to Wikipedia to get reliable information about different subjects, one of the most popular being living people, and especially politicians. While a lot is known about the general usage and information consumption on Wikipedia, less is known about the life-cycle and quality of Wikipedia articles in the context of politics. The aim of this study is to quantify and qualify content production and consumption for articles about politicians, with a specific focus on UK Members of Parliament (MPs).####First, we analyze spatio-temporal patterns of readers’ and editors’ engagement with MPs’ Wikipedia pages, finding huge peaks of attention during election times, related to signs of engagement on other social media (e.g. Twitter). Second, we quantify editors’ polarisation and find that most editors specialize in a specific party and choose specific news outlets as references. Finally we observe that the average citation quality is pretty high, with statements on ‘Early life and career’ missing citations most often (18%)."

We evaluate NER models on a dataset containing 139 years of U.S. census baby names and find that relatively more female names, as opposed to male names, are not recognized as PERSON entities. The result of this analysis yields a new benchmark for gender bias evaluation in named entity recognition systems. The data and code for the application of this benchmark is publicly available for researchers to use."

The Treasury contained millions of historical documents filling 100,000 square feet of shelving organised into 5,500 series of records accumulated over seven centuries. It was destroyed in one afternoon.####Beyond 2022 is an international collaborative research project based at the ADAPT Centre, Trinity College Dublin, and funded by the Government of Ireland. We are working to create a virtual reimagining of this lost national archive. Many millions of words from destroyed documents will be linked and reassembled from copies, transcripts and other records scattered among the collections of our archival partners. We will bring together this rich array of replacement items within an immersive 3-D reconstruction of the destroyed building.####In this keynote address, we will discuss the Digital Humanities and Knowledge Engineering challenges presented by the project, and also reflect on how this reimagining of a lost archive will provide deeper search and discoverability than was possible one hundred years ago when the archive was still in existence."
