    • 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 ...
    • Personalized Question Answering: A Use Case for Business Analysis 

      Thai, VinhTuan; O'Riain, Sean; Davis, Brian; O'Sullivan, David (2006)
      In this paper, we introduce the Personalized Question Answering framework, which aims at addressing certain limitations of existing domain specific Question Answering systems. Current development efforts are ongoing to ...
    • 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, 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 ...
    • Processing ontology alignments with SPARQL 

      Polleres, Axel (IEEE Computer Society, 2008)
    • 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 

      Nováček, Vít (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.
    • Robot-assisted care for elderly with dementia: is there a potential for genuine end-user empowerment? 

      Felzmann, Heike; Murphy, Kathy; Casey, Dympna; Beyan, Oya (2015)
    • The role of negative results for choosing an evaluation approach - a recommender systems case study 

      Heitmann, Benjamin; Hayes, Conor (CEUR Workshop Proceedings, 2015-06-01)
      We describe a case study, which shows how important negative results are in uncovering biased evaluation methodologies. Our re- search question is how to compare a recommender algorithm that uses an RDF graph to a ...
    • 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 relation classification: task formalisation and refinement 

      Silva, Vivian S.; Hürliman, Manuela; Davis, Brian; Handschuh, Siegfried; Freitas, André (Association for Computational Linguistics, 2016-12-12)
      The identification of semantic relations between terms within texts is a fundamental task in Natural Language Processing which can support applications requiring a lightweight semantic interpretation model. Currently, ...
    • 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 

      Nováček, Vít; 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 (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 ...
