Facilitating the Semantic Discovery of eGovernment Services: The SemanticGov Portal
ABSTRACT In this paper we propose a way to facilitate the issue of discovering the eGovernment services that address a citizen's need. This approach is implemented in an application, which we call a semantic portal. The semantic portal is part of our SemanticGov project architecture. The portal's components and its architecture are presented and explained. The portal's conceptual modeling is based on the generic public service object model of governance enterprise architecture (GEA) while Web service modeling ontology (WSMO) is used as the semantic Web services framework for application implementation. . We describe the ontologies required using the Web service modeling language (WSML). The reasoning tasks are performed accordingly using a WSML reasoner. Goals are WSMO elements that describe aspects related to user desires. The input to the application consists of information regarding the user's profile, i.e. age, marital status etc., while the output is a concrete WSMO Goal that expresses the citizen's need. This Goal is forwarded to the discovery engine, which has to discover all the services that address this Goal and return them to the citizen.

ABSTRACT: Currently thousands of services are available on the Web but the more services become available the harder it becomes to find and use them. Most of those services lack basic metadata that would improve their accessibility and discovery. In this work, we present a two-step approach for discovering services in the Web 2.0 environment. First, a formalized representation of the user's need is created and then based on that the services that match this need are discovered. The approach tries to make the most out of the available state of the art Semantic Web technologies. We use SA-REST as the annotation mechanisms and try to harvest the knowledge that can be extracted from social tagging.

ABSTRACT: In this paper we present how the atom interface can be used for browsing service registries and how this is applied in the case of an e-government services platform. Although e-government is a vibrant research domain, there is notably little work regarding HCI related issues. Our work shows the kind of problems that citizens face when using existing systems, and how new design approaches, like the atom interface, can facilitate the citizen-public administration interaction.To address domain specific needs we implemented several extentions to the Atom Interface. In addition, we defined mappings between e-Government concepts, i.e. service provider, administrative document etc, and elements of Atom. Our experience so far shows that public administration can provide a very good test-bed for the Atom Interface.Digital Information Management, 2008. ICDIM 2008.

Conference Paper: Ontology Modeling for Goal Driven E-Government[Show abstract] [Hide abstract]
ABSTRACT: This paper presents an approach to model ontologies in the e-Government domain so that they can be easily used to assist a citizen in formally expressing a goal that can in turn be used for service discovery. This process is also known as "goal discovery" and can become relatively complex depending on the regulations that have to be applied. By introducing some guidelines and constraints on the model, this process can be simplified and complexity can be hidden from the user. We found that the concept tree, used to guide the user in uniquely identifying the goal, is a good basis to start with, since it is easy to use and also easy to maintain in comparison to other approaches. Our next steps will be to automatically generate forms based on ontologies.System Sciences, 2009. HICSS '09. 42nd Hawaii International Conference on; 02/2009
