  • Semantic SOA to Promote Integration of Heterogeneous B2B Services 

    Vitvar, Tomas; Moran, Matthew; Zaremba, Maciej; Haller, Armin; Kotinurmi, Paavo (IEEE, 2007)
    Modeling the semantics of business services and their corresponding messages using ontologies enables flexible integration that is more adaptive to business-driven change. In this paper we demonstrate our approach building ...
  • Leveraging Ontologies, Context and Social Networks to Automate Photo Annotation 

    Monaghan, Fergal; O'Sullivan, David (Springer, 2007)
    This paper presents an approach to semi-automate photo an- notation. Instead of using content-recognition techniques this approach leverages context information available at the scene of the photo such as time and location ...
  • WSMO-PA: Formal Specification of Public Administration Service Model on Semantic Web Service Ontology 

    Wang, Xia; Peristeras, Vassilios; Vitvar, Tomas; Mocan, Adrian (IEEE, 2007)
    In this paper we define a formal model for a Public Ad- ministration service on the basis of the Web Service Modeling Ontology (WSMO). For this purpose we employ the generic public service object model of the Governance ...
  • E-Learning on the Social Semantic Information Sources 

    Kruk, Sebastian Ryszard; Gzella, Adam; Dobrzanski, Jaroslaw; McDaniel, Bill; Woroniecki, Tomasz (2007)
    E-Learning grows on the fertile soil of the Internet technologies; it fails, however, to reach their full potential. With new, emerging technologies of the second generation Internet there is even more to be captured and ...
  • Dynamic Service Discovery through Meta-Interactions with Service Providers 

    Vitvar, Tomas; Zaremba, Maciej; Moran, Matthew (Springer, 2007)
    Dynamic discovery based on semantic description of services is an essential aspect of the Semantic Web services integration process. Since not all data required for service discovery can always be included in service ...
  • Towards Semantic Interoperability (In-depth comparison of two approaches to solving Semantic Web Service Challenge mediation tasks) 

    Zaremba, Maciej; Vitvar, Tomas; Moran, Matthew (2007)
    This paper overviews and compares the DERI and DEI-Cefriel approaches to the SWS-Challenge workshop mediation scenario in terms of the utilized underlying technologies and delivered solutions. In the mediation scenario one ...
  • Sindice.com: Weaving the open linked data 

    Tummarello, Giovanni; Delbru, Renaud; Oren, Eyal (2007)
    Developers of SemanticWeb applications face a challenge with respect to the decentralised publication model: where to find statements about encountered resources. The linked data" approach, which man- dates that resource ...
  • A Prototype to Explore Content and Context on Social Community Sites 

    Bojars, Uldis; Heitmann, Benjamin; Oren, Eyal (2007)
    The SIOC Ontology can be used to express information from the online community sites in a machine readable form using RDF. This rich data structure allows us to easily analyse and extract social relations from these ...
  • Examination of the Impact of Emerging Technologies on eLearning 

    McDaniel, Bill; Kruk, Sebastian Ryszard (Association for the Advancement of Computing in Education, 2007)
    eLearning has, to date, mostly been a matter of content being displayed on PCs running Windows, Linux, or MAC OS. Emerging technologies have recently, however, expanded the capabilities and scope of portable and mobile ...
  • Infrastructure for data processing in large-scale interconnected sensor network 

    Aberer, Karl; Hauswirth, Manfred (2007)
    With the price of wireless sensor technologies diminishing rapidly we can expect large numbers of autonomous sensor networks being deployed in the near future. These sensor networks will typically not remain isolated but ...
  • Quantified equilibrium logic and hybrid rules 

    Polleres, Axel (Springer, 2007)
    In the ongoing discussion about combining rules and Ontologies on the Semantic Web a recurring issue is how to combine first-order classical logic with nonmonotonic rule languages. Whereas several modular approaches to de- ...
  • Handling heterogeneity in RosettaNet messages 

    Haller, Armin; Kotinurmi, Paavo; Vitvar, Tomas; Oren, Eyal (2007)
    We present a semantic B2B gateway based on the WSMX se- mantic Service-Oriented Architecture to tackle heterogeneities in RosettaNet messages. We develop a rich RosettaNet ontology and use the axiomatised knowledge and ...
  • Sharing information across community portals with FOAFRealm 

    Breslin, John; Grzonkowski, Slawomir; Gzella, Adam; Kruk, Sebastian Ryszard; Woroniecki, Tomasz (IADIS Press, 2007)
  • Towards Optimized Data Fetching for Service Discovery 

    Zaremba, Maciej; Vitvar, Tomas; Moran, Matthew (IEEE, 2007)
    The advent of Service Oriented Architecture makes services the most flexible, platform-independent choice for exposing and integrating business functionality across a network. However, the lack of service discovery mechanisms, ...
  • Simple algorithms for predicate suggestions using similarity and co-occurrence 

    Oren, Eyal; Gerke, Sebastian; Decker, Stefan (Association for Computing Machinery, 2007)
    When creating Semantic Web data, users have to make a critical choice for a vocabulary: only through shared vocabularies can meaning be established. A centralised policy prevents terminology divergence but would restrict ...
  • A Protégé Plug-in Development to Support the NEPOMUK Representational Language 

    Caires, Milena; Scerri, Simon; Handschuh, Siegfried (2007)
    In this document, we present the challenges faced to develop a plug-in for Protégé that supports requirements for the NEPOMUK1 Representational Language (NRL). NRL is a language built on top of RDF/S and ...
  • The Boardscape: Creating a Super Social Network of Message Boards 

    Breslin, John; Bojars, Uldis (AAAI, 2007)
    A Web-based message board or forum is an online area where discussions are held by many Internet users on a variety of subjects. More recently, online social networks have been created for various purposes: job searching, ...
  • Adapting informal sources of knowledge to e-Learning 

    Jankowski, Jacek; Czaja, Filip; Dobrzanski, Jaroslaw (2007)
  • YARS2: A Federated Repository for Querying Graph Structured Data from the Web 

    Harth, Andreas; Umbrich, Jürgen; Hogan, Aidan; Decker, Stefan (2007)
    We present the architecture of an end-to-end semantic search engine that uses a graph data model to enable interactive query answering over structured and interlinked data collected from many disparate sources on the Web. ...
  • A DRM Solution Based on Social Networks and Enabling the Idea of Fair Use 

    Grzonkowski, Slawomir; Ensor, Brian; Kruk, Sebastian Ryszard; Gzella, Adam; Decker, Stefan; McDaniel, Bill (2007)
    Fair use policy allows legal owners to share products they bought with their acquaintance; it is based on the assumptions that the owners pass an original product and they cannot use it at the same time. In the digital ...
