  • Podcast Pinpointer: A Multimedia Semantic Web Application 

    Hogan, Aidan; Harth, Andreas; Breslin, John (IEEE, 2005)
    In late 2004, a new method of publishing multimedia broadcasts on the Internet became popular called `Podcasting¿. Podcasting incorporates existing feed description formats, namely RSS 2.0, to ...
  • Processing ontology alignments with SPARQL 

    Polleres, Axel (IEEE Computer Society, 2008)
  • Processing ontology alignments with SPARQL 

    Polleres, Axel (IEEE, 2008)
    Solving problems raised by heterogeneous ontologies can be achieved by matching the ontologies and processing the resulting alignments. This is typical of data mediation in which the data must be translated from one ...
  • ReConRank: A Scalable Ranking Method for Semantic Web Data with Context 

    Hogan, Aidan; Harth, Andreas; Decker, Stefan (2006)
    We present an approach that adapts the well-known PageRank/HITS algorithms to Semantic Web data. Our method combines ranks from the RDF graph with ranks from the context graph, i.e. data sources and their linkage. We present ...
  • Relaxing the Basic KR&R Principles to Meet the Emergent Semantic Web 

    Novacek, Vit (CEUR-WS, 2008)
    The paper argues for an alternative, empirical (instead of analytical) approach to a Semantic Web-ready KR&R, motivated by the so far largely untackled need for a feasible emergent content processing.
  • SALT: Semantically Annotated LATEX 

    Groza, Tudor; Handschuh, Siegfried; Kim, Hak Lae (2006)
    Machine-understandable data constitutes the basis for the Semantic Desktop. We provide in this paper means to author and annotate Semantic Documents on the Desktop. In our approach, the PDF file format is the basis for ...
  • Scalable Authoritative OWL Reasoning on a Billion Triples 

    Hogan, Aidan; Harth, Andreas; Polleres, Axel (2008)
    In this paper we present a scalable algorithm for performing a subset of OWL reasoning over web data using a rule-based approach to forward-chaining; in particular, we identify the problem of ontology hijacking: new ...
  • Semantic Social Collaborative Filtering with FOAFRealm 

    Kruk, Sebastian Ryszard; Decker, Stefan (2005)
    The most popular collaborative filtering implementations require either a critical mass of referenced resources and a lot of active users. Other solutions are based on finding a referral with an expertise on the given ...
  • Semantic Web Services enabled B2B Integration 

    Kotinurmi, Paavo; Vitvar, Tomas; Haller, Armin (2006)
    The use of Semantic Web Service (SWS) technologies have been suggested to enable more dynamic B2B integration of heterogeneous systems and partners. We present our approach to accomplish dynamic B2B integrations based on ...
  • Semi-automatic Integration of Learned Ontologies into a Collaborative Framework 

    Novacek, Vit; Handschuh, Siegfried (2007)
    The paper presents a novel ontology lifecycle scenario that explicitly takes the dynamics and data-intensiveness of real world applications into account. Changing and growing knowledge is handled by semi-automatic ...
  • SIOC: Content Exchange and Semantic Interoperability Between Social Networks 

    Breslin, John; Bojars, Uldis; Passant, Alexandre; Fernández, Sergio; Decker, Stefan (2009)
    This paper describes work performed during the last few years in the context of the SIOC project in order to model social data on the Web using Semantic Web technologies. We will give an overview of the SIOC model, ...
  • Social Networking Portals: An Overview and Evaluation 

    O'Murchu, Ina; Breslin, John; Decker, Stefan (2004)
    Next generation communication on the Internet changes the way we interact with the complexity of the information load on the World Wide Web. Web portals act as gateways to resources and a multitude of services on the ...
  • Social Networks and Data Portability using Semantic Web technologies 

    Bojars, Uldis; Breslin, John; Decker, Stefan (2008)
    Social network and data portability has recently gained a lot of interest as one of the issues for social media sites on the Web. In this paper, we will show how Semantic Web technologies and especially the FOAF and ...
  • SWSE: Answers Before Links! 

    Harth, Andreas; Hogan, Aidan; Delbru, Renaud; Umbrich, Jürgen; O'Riain, Sean; Decker, Stefan (, 2007)
    We present a system that improves on current document- centric Web search engine technology; adopting an entity-centric perspective, we are able to integrate data from both static and live sources into a coherent, interlinked ...
  • SWSE: Objects before documents! 

    Harth, Andreas; Hogan, Aidan; Umbrich, Jürgen; Decker, Stefan (2008)
    Web search engines are immensely useful for locating documents online. However, with more and more structured data being published online, the restriction to the hyperdocument model impairs the usefulness for searching and ...
  • Towards a Practical Emergent Knowledge Exploitation 

    Novacek, Vit (AAAI Press, 2009)
  • Towards a social provenance model for the Web 

    Harth, Andreas; Polleres, Axel; Decker, Stefan (2007)
    In this position paper we firstly present the established notion of provenance on the Semantic Web (also referred to as named graphs or contexts), and secondly argue for the benefit of adding to the pure technical notion ...
  • Towards Constraint-Based Composition With Incomplete Service Descriptions 

    Moran, Matthew; Vitvar, Tomas; Zaremba, Maciej (IEEE, 2007)
    We apply our work on Web service discovery with initially incomplete information to the problem of service com- position. Rich semantic descriptions of Goals and Web ser- vices allow the unambiguous specification of ...
  • Towards Cross-Community Effects in Scientific Communities 

    Karnstedt, Marcel; Hayes, Conor (2009)
    Community effects on the behaviour of individuals, the community itself and other communities can be observed in a wide range of applications. This is true in scientific research, where communities of researchers have ...
