  • An Eigenvalue-Based Measure for Word-Sense Disambiguation 

    Hulpus, Ioana; Hayes, Conor; Greene, Derek (FLAIRS 2012, 2012)
    Current approaches for word-sense disambiguation (WSD) try to relate the senses of the target words by optimizing a score for each sense in the context of all other words' senses. However, by scoring each sense separately, ...
  • Entailment for Domain-restricted RDF 

    Polleres, Axel (Springer, 2008)
    We introduce domain-restricted RDF (dRDF) which allows to associate an RDF graph with a fixed, finite domain that interpretations for it may range over. We show that dRDF is a real extension of RDF and discuss impacts on ...
  • 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 ...
  • Examination of the Impact of Emerging Technologies on eLearning 

    McDaniel, Bill; Kruk, Sebastian Ryszard (Association for the Advancement of Computing in Education, 2007)
    eLearning has, to date, mostly been a matter of content being displayed on PCs running Windows, Linux, or MAC OS. Emerging technologies have recently, however, expanded the capabilities and scope of portable and mobile ...
  • Extending Community Ontology Using Automatically Generated Suggestions 

    Novacek, Vit; Dabrowski, Maciej; Kruk, Sebastian Ryszard; Handschuh, Siegfried (AAAI Press, 2007)
    In this paper we propose an ontology (formal knowledge base) creation methodology based on integrating external ontologies into the one developed by a community of the do- main experts. We present the MarcOntX agent, a ...
  • 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 ...
  • Four Heuristics to Guide Structured Content Crawling 

    Umbrich, Jürgen; Harth, Andreas; Hogan, Aidan; Decker, Stefan (2008)
    Search engines focusing on particular media types face difficulties in discovering suitable URIs on the Web. Since the engines are only interested in a small fraction of the Web, a crawler should use heuristics to concentrate ...
  • Freshening up while Staying Fast: Towards Hybrid SPARQL Queries 

    Umbrich, Jürgen; Karnstedt, Marcel; Hogan, Aidan; Parreira, Josiane Xavier (2012)
  • Geographic Routing in Wireless Multimedia Sensor Networks 

    Shu, Lei; Hauswirth, Manfred (IEEE, 2008)
    In this paper, a -Phase geographic GreeTwody Forwarding (TPGF) routing algorithm is proposed in wireless multimedia sensor networks (WMSNs). TPGF is a pure geographic greedy forwarding routing algorithm, which does not ...
  • 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 ...
  • Heterogeneity and Context in Semantic-Web-Enabled HCLS Systems 

    Zimmermann, Antoine; Sahay, Ratnesh; Fox, Ronan; Polleres, Axel (Springer, 2009)
    The need for semantics preserving integration of complex data has been widely recognized in the healthcare domain. While standards such as Health Level Seven (HL7) have been developed in this direction, they have mostly ...
  • Hybrid SPARQL queries: fresh vs. fast results 

    Umbrich, Jurgen; Karnstedt, Marcel; Hogan, Aidan; Parreira, Xavier (2012)
  • IKHarvester Informal eLearning with SemanticWeb Harvesting 

    Jankowski, Jacek; Westerski, Adam; Kruk, Sebastian Ryszard; Nagle, Tadhg; Dobrzanski, Jaroslaw (IEEE, 2008)
    Only recently, researchers and practitioners alike have begun to fully understand the potential of eLearning and have concentrated on new tools and technologies for creating, capturing and distributing knowledge. In order ...
  • Imprecise Empirical Ontology Refinement: Application to Taxonomy Acquisition 

    Novacek, Vit (INSTICC, 2007)
    The significance of uncertainty representation has become obvious in the Semantic Web community recently. This paper presents new results of our research on uncertainty incorporation into ontologies created automatically ...
  • Infrastructure for data processing in large-scale interconnected sensor network 

    Aberer, Karl; Hauswirth, Manfred (2007)
    With the price of wireless sensor technologies diminishing rapidly we can expect large numbers of autonomous sensor networks being deployed in the near future. These sensor networks will typically not remain isolated but ...
  • Innovative Solution to Service Discovery and Integration using WSMOLX 

    Zaremba, Maciej; Zaharia, Raluca; Vitvar, Tomas (Springer, 2008)
    WSMX is a Semantic Web services broker enabling dynamic discovery and agile B2B integration of enterprise services. Our framework enables on-demand service discovery encompassing frequently changing aspects like fine-grained ...
  • Integrating Developer-related information across Open Source Repositories 

    Iqbal, Aftab; Hausenblas, Michael (2012)
    Software developers use various software repositories in order to interact with each other or to solve software related problems. They are required to adopt an identity for each of the software repositories they wanted to ...
