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.
Conference Proceeding: A Tool for Annotating Services with Domain Specific Semantics[show abstract] [hide abstract]
ABSTRACT: Semantic Web service (SWS) ontologies and tools are used in a generic fashion that is supposed to cover all different application domains. As such they have not supported until now the expression of domain specific semantics. However, the adoption of SWS in different domains, i.e. eGovernment, eBusiness, creates the need for instantiating and enhancing the generic SWS descriptions and tools with domain specific semantics. Therefore, domain specific models and customized tools that allow this integration should be developed. The WSMO-PA Service Editor is an effort made towards this direction as a specialised SWS editor with a friendly user interface which facilitates the creation of semantically-enhanced descriptions for public administration (PA) services. To achieve this domain customization, the WSMO-PA Service Editor uses a generic SWS editor (WSMO Studio), concepts from PA domain models (GEA PA service model), the WSMO-PA specification and the WSMO/F/L Framework.Semantic Computing, 2008 IEEE International Conference on; 09/2008
Conference Proceeding: 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
Conference Proceeding: Browsing service registries using the Atom Interface: An application in e-Government[show abstract] [hide abstract]
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.
