  • Dynamic Ontology Lifecycle Scenario in Translational Medicine 

    Novacek, Vit; Handschuh, Siegfried (Oxford University Press, 2007)
    In this paper, we present a healthcare¿oriented vision of dynamic ontology lifecycle that has been recently developed within Knowledge Web ¿ EU Network of Excellence aimed at transition of Semantic Web technologies to ...
  • Dynamic Querying of Mass-Storage RDF Data with Rule-Based Entailment Regimes 

    Krennwallner, Thomas; Martello, Alessandra; Polleres, Axel (Springer, 2009)
    RDF Schema (RDFS) as a lightweight ontology language is gaining popularity and, consequently, tools for scalable RDFS inference and querying are needed. SPARQL has become recently aW3C standard for querying RDF data, ...
  • Dynamic Service Discovery through Meta-Interactions with Service Providers 

    Vitvar, Tomas; Zaremba, Maciej; Moran, Matthew (Springer, 2007)
    Dynamic discovery based on semantic description of services is an essential aspect of the Semantic Web services integration process. Since not all data required for service discovery can always be included in service ...
  • E-learning based on the Social Semantic Information Sources 

    Westerski, Adam; Kruk, Sebastian Ryszard; Samp, Krystian; Woroniecki, Tomasz; Czaja, Filip; O'Nuallain, Caoimhin (2006)
    E-Learning is no longer just about the materials burned on CD-ROMs and sent across the country. With the potential offered by the Internet, there are new on-line courses emerging every day. However successful they are, ...
  • E-learning based on the Social Semantic Information Sources 

    Westerski, Adam; Kruk, Sebastian Ryszard; Samp, Krystian; Woroniecki, Tomasz; Czaja, Filip; O'Nuallain, Caoimhin (2006)
    E-Learning is no longer just about the materials burned on CD-ROMs and sent across the country. With the potential offered by the Internet, there are new on-line courses emerging every day. However successful they are, ...
  • E-Learning on the Social Semantic Information Sources 

    Kruk, Sebastian Ryszard; Gzella, Adam; Dobrzanski, Jaroslaw; McDaniel, Bill; Woroniecki, Tomasz (2007)
    E-Learning grows on the fertile soil of the Internet technologies; it fails, however, to reach their full potential. With new, emerging technologies of the second generation Internet there is even more to be captured and ...
  • 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, ...
  • Embedding non-ground logic programs into autoepistemic logic for knowledge base combination 

    Polleres, Axel (2011)
    In the context of the Semantic Web, several approaches to the combination of ontologies, given in terms of theories of classical first-order logic and rule bases, have been proposed. They either cast rules into classical ...
  • An Empirical Investigation of Networks in the Blogosphere 

    Bojars, Uldis; Harth, Andreas; Kinsella, Sheila (2007)
    We seek out to investigate the social networks manifested in weblogs. Our dataset, derived from an initial list of URIs, consists of 3.9M files in XML or RDF format, totaling over 400M statements in RDF. We continue ...
  • Enabling Trust and Privacy on the Social Web 

    Passant, Alexandre; Hausenblas, Michael; Polleres, Axel; Decker, Stefan (2009)
  • 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 ...
  • enVision: An integrated approach towards Semantic Authoring 

    Groza, Tudor; Handschuh, Siegfried; Decker, Stefan (2006)
    Writing is one of the most common activities of a researcher. And since, the writing process is not only about writing, but also about researching the background of the domain or collecting the necessary references, we ...
  • 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 ...

  • EUREEKA: Deepening the Semantic Web by More Efficient Emergent Knowledge Representation and Processing 

    Novacek, Vit (CEUR-WS, 2008)
    One of the major Semantic Web challenges is the knowledge acquisition bottleneck. New content on the web is produced much faster than the respective machine readable annotations, while a scalable knowledge extraction ...
  • 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 ...
  • The ExpertFinder Corpus 2007 for the Benchmarking and Development of ExpertFinding Systems 

    Hogan, Aidan; Harth, Andreas (2007)
    We provide a benchmark dataset for expert finding within the computer science domain. We show how large isolated data graphs from disparate structured data sources can be combined to form one, large, well-linked RDF graph ...
