Using Semantic Web Technologies to Support Information Processing and Coalition Decision-Making

Abstract

This paper outlines three techniques and tools which have recently arisen from Semantic Web research in the International Technology Alliance. The first of these techniques is POAF (Portable Ontology Aligned Fragments), which addresses issues relating to the portability and usage of ontology alignments. POAF uses an ontology fragmentation strategy to achieve portability, and it enables subsequent usage of ontologies through a form of automated ontology modularization. The second technique, SWEDER (Semantic Wrapping of Existing Data sources with Embedded Rules), is grounded in the creation of lightweight ontologies to semantically wrap existing data sources, which facilitates rapid semantic integration through representational homogeneity and embedded rules. The third technique is NITELIGHT, which is a tool that has been created to better support end users with respect to the creation and editing of semantic queries. NITELIGHT uses a visual query language, called vSPARQL, and it is based on the W3C SPARQL query language specification. NITELIGHT supports end users by providing a set of graphical notations that represent semantic query language constructs. These enable the user to combine ontology navigation capabilities with graphical query visualisation techniques.
