    • OWL DL vs. OWL Flight: Conceptual Modeling and Reasoning for the Semantic Web 

      Polleres, Axel; Fensel, Dieter (2005)
      The Semantic Web languages RDFS and OWL have been around for some time now. However, the presence of these languages has not brought the breakthrough of the Semantic Web the creators of the languages had hoped for. OWL has ...
    • JeromeDL - Adding Semantic Web Technologies to Digital Libraries 

      Kruk, Sebastian Ryszard; Decker, Stefan (Springer, 2005)
      In recent years more and more information has been made available on the Web. High quality information is often stored in dedicated databases of digital libraries, which are on their way to become expanding islands of well ...

    • D-FOAF - Security Aspects in Distributed User Management System 

      Grzonkowski, Slawomir; Gzella, Adam; Kruk, Sebastian Ryszard; Woroniecki, Tomasz (IEEE, 2005)
      The contemporary Internet offers various services ranging from electronic newspapers to on- line social networks. To authorize themselves, users have to register to on-line services. However, most of the ...
    • Automatic Location of Services 

      Keller, Uwe; Polleres, Axel; Fensel, Dieter (2005)
      The automatic location of services that fulfill a given need is seen as a key step towards dynamic and scalable integration. In this paper we present a model for the automatic location of services that considers the static ...
    • WWW or What Is Wrong with Web Services 

      Polleres, Axel; Bussler, Christoph; Fensel, Dieter (IEEE, 2005)
      A core paradigm of the Web is information exchange via persistent publication, i.e., one party publishes a piece of information on the Web, and any other party who knows the location of the resource can retrieve and process ...
    • Towards Intelligent web Services: Web Service Modeling Ontology (WSMO) 

      Polleres, Axel; Fensel, Dieter (Springer, 2005)
      The SemanticWeb and the SemanticWeb Services build a natural application area for Intelligent Agents, namely querying and reasoning about structured knowledge and semantic descriptions of services and their interfaces on ...
    • E-learning based on the Social Semantic Information Sources 

      Westerski, Adam; Kruk, Sebastian Ryszard; Samp, Krystian; Woroniecki, Tomasz; Czaja, Filip; O'Nuallain, Caoimhin (2006)
      E-Learning is no longer just about the materials burned on CD-ROMs and sent across the country. With the potential offered by the Internet, there are new on-line courses emerging every day. However successful they are, ...
    • Cost-Aware Processing of Similarity Queries in Structured Overlays 

      Karnstedt, Marcel; Hauswirth, Manfred (2006)
      Large-scale distributed data management with P2P systems requires the existence of similarity operators for queries as we cannot assume that all users will agree on exactly the same schema and value representations and ...
    • Towards European Patient Summaries based on Triple Space Computing 

      Foxvog, Doug (2006)
      Medical practice today still entails sorting through scattered information on a specific patient. Making things more difficult, the EU, in bringing its member states closer together, is encouraging people¿s mobility, and ...
    • Extending faceted navigation for RDF data 

      Oren, Eyal; Delbru, Renaud; Decker, Stefan (2006)
      Data on the Semantic Web is semi-structured and does not follow one fixed schema. Faceted browsing is a natural technique for navigating such data, partitioning the information space into orthogonal conceptual dimensions. ...
    • Semantic Versioning Manager: Integrating SemVersion in Protégé 

      Groza, Tudor; Handschuh, Siegfried (2006)
      Knowledge domains and their semantic representations via ontologies are typically subject to change in practical applications. Additionally, engineering of ontologies often takes place in distributed settings where multiple ...
    • SAGE: An Ambient Intelligent Framework for Manufacturing 

      Hynes, Gearoid; Monaghan, Fergal; Thai, VinhTuan; O'Sullivan, David (2006)
      To profit in today¿s market, small manufacturers must be efficient and agile to minimise cost and to meet variable market demand. This paper discusses an envisaged Semantic, Ambient, Generic and Extensible framework ...
    • Building a Heterogeneous Network of Digital Libraries on the Semantic Web 

      Piotrowski, Piotr; Cygan, Mariusz; Kruk, Sebastian Ryszard; Westerski, Adam; Samp, Krystian; Decker, Stefan (2006)
      Ever since computer networks have become popular libraries tend to join into federations. Each federated digital library, apart from delivering discovery and navigation features within their own database allows users to ...
    • E-learning based on the Social Semantic Information Sources 

      Westerski, Adam; Kruk, Sebastian Ryszard; Samp, Krystian; Woroniecki, Tomasz; Czaja, Filip; O'Nuallain, Caoimhin (2006)
      E-Learning is no longer just about the materials burned on CD-ROMs and sent across the country. With the potential offered by the Internet, there are new on-line courses emerging every day. However successful they are, ...
    • Semantic Wikis for Personal Knowledge Management 

      Oren, Eyal; Breslin, John; Decker, Stefan (Springer, 2006)
      Wikis are becoming popular knowledge management tools. Analysing knowledge management requirements, we observe that wikis do not fully support structured search and knowledge reuse. We show how Semantic wikis address the ...
    • D-FOAF: Distributed Identity Management with Access Rights Delegation 

      Kruk, Sebastian Ryszard; Grzonkowski, Slawomir; Gzella, Adam; Woroniecki, Tomasz; Choi, Hee Chul (2006)
      WWW provides a large number of services, which often require identification of it¿s users. This has lead to the fact that today users have to maintain a large number of different credentials for different websites - ...
    • WSMX: A Semantic Service Oriented Middleware for B2B Integration 

      Kotinurmi, Paavo; Moran, Matthew; Vitvar, Tomas; Zaremba, Maciej (Springer, 2006)
