  • ActiveRDF: Object-oriented semantic web programming 

    Oren, Eyal; Delbru, Renaud; Gerke, Sebastian; Haller, Armin; Decker, Stefan (Association for Computing Machinery, 2007)
    Object-oriented programming is the current mainstream programming paradigm but existing RDF APIs are mostly triple-oriented. Traditional techniques for bridging a similar gap between relational databases and object-oriented ...
  • Annotation-Based Access Control for e-Professionals 

    Nasirifard, Peyman; Peristeras, Vassilios (2008)
    Collaborative Working Environments (CWE) provide shared workspaces that enable eProfessionals to work together and share resources that they own. Most current shared workspaces provide coarse-grained role-based access ...
  • 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 ...
  • 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, ...
  • 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 ...
  • 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 ...
  • Data Portability with SIOC and FOAF 

    Bojars, Uldis; Passant, Alexandre; Breslin, John (2008)
    Data portability has become an important requirement on the Social Web. This paper describes how data and social network portability can be achieved by building upon existing Semantic Web developments such as SIOC and FOAF. ...
  • The Development of A Realistic Simulation Framework with OMNeT++ 

    Shu, Lei (IEEE, 2008)
    It is necessary to use simulation tools in the study of wireless network. The object-oriented modular discrete event network simulator, OMNeT++, can not only afford many network simulation but has strong GUI support 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 ...
  • 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, ...
  • Establishing a distributed system for the simple representation and integration of diverse scientific assertions 

    Samwald, Matthias; Stenzhorn, Holger (Biomed, 2009)
    Information technology has the potential to increase the pace of scientific progress by helping researchers in formulating, publishing and finding information. There are numerous projects that employ ontologies and Semantic ...
  • Evaluation of Semantic and Social Technologies for Digital Libraries 

    Kruk, Sebastian Ryszard; Kruk, Ewelina (2008)
    Libraries are the tools we use to learn and to answer our questions. The quality of our work depends, among others, on the quality of the tools we use. Recently, the semantic web and social networking technologies are ...
  • 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. ...
  • Extracting and Utilizing Social Networks from Log Files of Shared Workspaces 

    Nasirifard, Peyman; Peristeras, Vassilios; Hayes, Conor; Decker, Stefan (Springer, 2009)
    Log files of online shared workspaces contain rich information that can be further analyzed. In this paper, log-file information is used to extract object-centric and user-centric social networks. The object-centric social ...
  • Federating Distributed Social Data to Build an Interlinked Online Information Society 

    Passant, Alexandre; Samwald, Matthias; Breslin, John; Decker, Stefan (2009)
    While research on the relation- ship between the Semantic Web and social media was originally motivated by the lack of semantics in mainstream Web 2.0 ser- vices, this vision can go much further, impacting society at large ...
  • 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 ...
  • IKHarvester Informal eLearning with SemanticWeb Harvesting
