    • 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 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 ...
    • 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 ...
    • SemStim at the Linked Open Data-enabled Recommender Systems 2014 challenge 

      Heitmann, Benjamin; Hayes, Conor (Springer, 2014-10-14)
      SemStim is a graph-based recommendation algorithm which is based on Spreading Activation and adds targeted activation and duration constraints. SemStim is not affected by data sparsity, the cold-start problem or data quality ...
    • SESA: Emerging Technology for Service-Centric Environments 

      Vitvar, Tomas; Zaremba, Michal; Zaremba, Maciej; Moran, Matthew; Fensel, Dieter (Institute of Electrical and Electronics Engineers, 2007)
      Service-oriented architectures - and particularly the Web service technologies that enable them, such as WSDL (Web Services Description Language) and SOAP - are widely acknowledged for their potential to revolutionize ...
    • 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 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 ...
    • SPARQL++ for mapping between RDF vocabularies 

      Polleres, Axel (Springer, 2007)
      Lightweight ontologies in the formof RDF vocabularies such as SIOC, FOAF, vCard, etc. are increasingly being used and exported by ¿serious¿ applications recently. Such vocabularies, together with query languages like SPARQL ...
    • 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 Fine-grained Service Matchmaking by Using Concept Similarity 

      Polleres, Axel (2007)
      Several description frameworks to semantically describe and match services on the one hand and service requests on the other have been presented in the literature. Many of the current proposals for defining notions of ...
    • 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 ...
    • Weaving SIOC into the Web of Linked Data 

      Bojars, Uldis; Passant, Alexandre; Cyganiak, Richard; Breslin, John (2008)
      Social media sites can act as a rich source of large amounts of data by letting anyone easily create content on the Web. The SIOC ontology and tools developed for it allow us to express this information as interlinked RDF ...
