  • An Interactive Map of Semantic Web Ontology Usage 

    Kinsella, Sheila; Bojars, Uldis; Harth, Andreas; Breslin, John; Decker, Stefan (IEEE, 2008)
    Publishing information on the Semantic Web using common formats enables data to be linked together, integrated and reused. In order to fully leverage the potential for interlinking data by reusing existing schemas, an ...
  • 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 ...
  • JeromeDL and FOAFRealm - Taking Advantage of Semantic Social Collaborative Filtering in Digital Libraries 

    Kruk, Sebastian Ryszard; Decker, Stefan (2005)
    In this paper, we present FOAFRealm, a user management library based on social networking and FOAF metadata, and its deployment in JeromeDL, a digital library with semantics. We will demonstrate the most important ...
  • KonneXSALT: First Steps Towards a Semantic Claim Federation Infrastructure 

    Groza, Tudor; Handschuh, Siegfried; Möller, Knud; Decker, Stefan (Springer, 2008)
    Dissemination, an important phase of scientific research, can be seen as a communication process between scientists. They expose and support their findings, while discussing claims stated in related scientific publications. ...
  • On the Ostensibly Silent 'W' in OWL 2 RL 

    Hogan, Aidan; Decker, Stefan (Springer, 2009)
    In this paper, we discuss the draft OWL 2 RL proable from the perspective of applying the constituent rules over Web data. In particular, borrowing from previous work, we discuss (i) optimisations based on a separation ...
  • Performing Object Consolidation on the Semantic Web Data Graph 

    Hogan, Aidan; Harth, Andreas; Decker, Stefan (2007)
    An important aspect of Semantic Web technologies is the issue of identity and uniquely identifying resources, which is essential for integrating data across sources. Currently, there is poor agreement on the use of ...
  • Produce and Consume Linked Data with Drupal! 

    Corlosquet, Stéphane; Delbru, Renaud; Polleres, Axel; Decker, Stefan (Springer, 2009)
    Currently a large number of Web sites are driven by Content Management Systems (CMS) which manage textual and multimedia content but also - inherently - carry valuable information about a site¿s structure and content ...
  • Protect Your RDF Data! 

    Kirrane, Sabrina; Lopes, Nuno; Mileo, Alessandra; Decker, Stefan (2012)
    The explosion of digital content and the heterogeneity of enterprise content sources have pushed existing data integration solutions to their boundaries. Although RDF can be used as a representation format for integrated data, ...
  • 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 ...
  • 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 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 ...
  • 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 ...
  • Sindice Widgets: Lightweight embedding of Semantic Web capabilities into existing user applications 

    Westerski, Adam; Iqbal, Aftab; Tummarello, Giovanni; Decker, Stefan (2008)
    In this paper we present a methodology by which it is possible to enhance existing web applications and directly deliver to the end users aggregated ¿views¿ of information. These views are accessed by clicking on buttons ...
  • 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 (CEUR-WS.org, 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 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 ...
