  • Discovery of Optimized Web Service Configurations Using a Hybrid Semantic and Statistical Approach 

    Zaremba, Maciej; Migdal, Jacek; Hauswirth, Manfred (IEEE, 2009)
    We present a Semantic Optimized Service Discovery (Se- mOSD) approach capable of handling Web service search requests on a fine-grained level of detail where we augment semantic service descriptions with statistically built ...
  • A Distributed Semantic Microblogging Platform 

    Passant, Alexandre; Hastrup, Tuukka; Bojars, Uldis; Breslin, John (2008)
    The application showcases the ideas of a distributed, Semantic-Web enabled micro blogging architecture, providing a way to leverage this new Web 2.0 practice to the Semantic Web.
  • dlvhex-sparql: A SPARQL-compliant query engine based on dlvhex 

    Polleres, Axel (CEUR, 2007)
    This paper describes the dlvhex SPARQL plugin, a query processor for the upcoming Semantic Web query language standard by W3C. We report on the implementation of this languages using dlvhex, a flexible plugin system ...
  • A DRM Solution Based on Social Networks and Enabling the Idea of Fair Use 

    Grzonkowski, Slawomir; Ensor, Brian; Kruk, Sebastian Ryszard; Gzella, Adam; Decker, Stefan; McDaniel, Bill (2007)
    Fair use policy allows legal owners to share products they bought with their acquaintance; it is based on the assumptions that the owners pass an original product and they cannot use it at the same time. In the digital ...
  • Dynamic Integration of Medical Ontologies in Large Scale 

    Nováček, Vít; Handschuh, Siegfried (ACM Press, 2007)
  • Dynamic Ontology Lifecycle Scenario in Translational Medicine 

    Nováček, Vít; 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 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 case-based reasoning on the web of data 

    Heitmann, Benjamin; Hayes, Conor (2010-07-20)
    While Case-based reasoning (CBR) has successfully been deployed on the Web, its data models are typically inconsistent with existing information infrastructure and standards. In this paper, we examine how CBR can operate ...
  • 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 Central, 2011)
    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 ...
