    A semantic web service-based architecture for the interoperability of e-government services

    We propose a semantically-enhanced architecture to address the issues of interoperability and service integration in e-government web information systems. An architecture for a life event portal based on Semantic Web Services (SWS) is described. The architecture includes loosely-coupled modules organized in three distinct layers: User Interaction, Middleware and Web Services. The Middleware provides the semantic infrastructure for ontologies and SWS. In particular a conceptual model for integrating domain knowledge (Life Event Ontology), application knowledge (E-government Ontology) and service description (Service Ontology) is defined. The model has been applied to a use case scenario in e-government and the results of a system prototype have been reported to demonstrate some relevant features of the proposed approach

    Supporting public decision making in policy deliberations: An ontological approach

    This is the post-print version of the Paper. The official published version can be accessed from the link below - Copyright @ 2011 SpringerSupporting public decision making in policy deliberations has been a key objective of eParticipation which is an emerging area of eGovernment. EParticipation aims to enhance citizen involvement in public governance activities through the use of information and communication technologies. An innovative approach towards this objective is exploiting the potentials of semantic web technologies centred on conceptual knowledge models in the form of ontologies. Ontologies are generally defined as explicit human and computer shared views on the world of particular domains. In this paper, the potentials and benefits of using ontologies for policy deliberation processes are discussed. Previous work is then extended and synthesised to develop a deliberation ontology. The ontology aims to define the necessary semantics in order to structure and interrelate the stages and various activities of deliberation processes with legal information, participant stakeholders and their associated arguments. The practical implications of the proposed framework are illustrated.This work is funded by the European Commission under the 2006/1 eParticipation call

    A Business Ontology for supporting cross border cooperation between European Chambers of Commerce

    The recent EU enlargement opens up new opportunities, but poses new issues to be addressed. In particular, in order to enable and support cooperation between firms from different countries, it is necessary to address interoperability issues. The LD-CAST project aims at enabling cross border cooperation between European chambers of commerce (CCs) for supporting the development of private company initiatives. The project objective is to build a European network of portals that will enable end users (mainly private companies) to access in a seamless mode services provided by public organizations registered in each portal. This paper briefly presents a cooperation framework for semantic interoperability mainly based on the following semantic technologies: ontology management, semantic annotation, and semantic search and discovery. Finally the business ontology produced in the course of the project is presented.The recent EU enlargement opens up new opportunities, but poses new issues to be addressed.

    IRS-III: A broker-based approach to semantic Web services

    Get PDF
    A factor limiting the take up of Web services is that all tasks associated with the creation of an application, for example, finding, composing, and resolving mismatches between Web services have to be carried out by a software developer. Semantic Web services is a combination of semantic Web and Web service technologies that promise to alleviate these problems. In this paper we describe IRS-III, a framework for creating and executing semantic Web services, which takes a semantic broker based approach to mediating between service requesters and service providers. We describe the overall approach and the components of IRS-III from an ontological and architectural viewpoint. We then illustrate our approach through an application in the eGovernment domain

    Metadata interoperability in public sector information

    Get PDF
    Over recent years, there has been a worldwide growing need for interoperability among the systems that manage and reuse Public Sector Information. This paper explores the documentation needs for Public Sector Information and focuses on metadata interoperability issues. The research work studies a variety of public sector information metadata standards and guidelines internationally accepted and presents two methodologies to obtain interoperability: The first develops an Application Profile, while the second is based on the semantic integration approach and results in the creation of an ontology. The outcomes of the two approaches are compared under the prism of their scope and usage in terms of interoperability during the metadata integration process

    Modeling Business Models: A cross-disciplinary Analysis of Business Model Modeling Languages and Directions for Future Research

    Get PDF
    Modeling languages for business models are a powerful and flexible means of representing and communicating knowledge related to business models. More than fifteen years after Osterwalder et al. (2005) clarified the ontology for the business model concept in this journal, we offer a systematic and cross-disciplinary assessment of the literature on business model modeling languages (BMMLs) that facilitate the visualization of this concept. In so doing, we synthesize and organize the knowledge dispersed across different disciplines in which BMMLs have originated and highlight the potential weaknesses in this literature to offer solid insights for future research. Our analysis reveals the existence of 17 BMMLs that have originated in traditional domains such as strategy and information systems, but also emerging domains such as sustainability. We contrast and compare these BMMLs along three dimensions: semantics, syntax, and pragmatics. We also analyze research that has made use of these BMMLs, differentiating between research that is conducted with a given BMML and research that is conducted about a given BMML. We conclude by offering a research agenda in which we illustrate the main challenges associated with the lack of well-accepted semantic, syntactic, and pragmatic foundations of BMMLs and outline opportunities for future research

    Deploying Semantic Web Services-Based Applications in the e-Government Domain

    Get PDF
    Joining up services in e-Government usually implies governmental agencies acting in concert without a central control regime. This requires to the sharing scattered and heterogeneous data. Semantic Web Service (SWS) technology can help to integrate, mediate and reason between these datasets. However, since a few real-world applications have been developed, it is still unclear which are the actual benefits and issues of adopting such a technology in the e-Government domain. In this paper, we contribute to raising awareness of the potential benefits in the e-Government communityby analyzing motivations, requirements and expected results, before proposing a reusable SWS-based framework. We demonstrate the application of this framework by showing how integration and interoperability emerge from this model through a cooperative and multi-viewpoint methodology. Finally, we illustrate added values and lessons learned by two compelling case studies: a change of circumstances notification system and a GIS-based emergency planning system, and describe key challenges which remain to be addressed
