Description/Abstract

Public Administration clients often face difficulties using Public Administration Services. Some of these problems include that the PA clients are needs-aware but PA agencies are only service-aware. This forces clients to search for appropriate services that would fulfill their needs and also to check if they are eligible for using this service by themselves. Even if they know the procedure that needs to be followed they often must go from one Public Agency to another in order to gather the required documents and information. The Semantic Gov research project proposes an infrastructure which uses Web Services, SOA and Semantic Web Services in order to help PA clients find the services that fulfill their needs. Clients are able to check if they are eligible to use the service and, if so, by using their own person personal profile, they can find the appropriate version of the service they require. This architecture also provides interoperability between different PA agencies both within the country as well as the PA agencies in other countries. This saves the client having to deliver documents from one agency to another especially for services that require international cooperation. This undergraduate thesis presents one of the two showcases where a Bulgarian citizen wants to acquire Greek citizenship. The first few chapters of this thesis provide a background of the technologies used in the architecture. The infrastructure consists of Web Services which is a realization technology of SOA and uses XML for communication and to describe their interfaces. The Semantic Web and its technologies and the combination of this with Web Services forms the Semantic Web Services. The latter provides semantic descriptions to Web Services in order to enhance the Web Service Discovery, composition, invocation and monitoring of Services. The outcome is that providing such a services as described in this thesis would be efficatious, time saving for clients and cost saving.
