  • Cost-Aware Processing of Similarity Queries in Structured Overlays 

    Karnstedt, Marcel; Hauswirth, Manfred (2006)
    Large-scale distributed data management with P2P systems requires the existence of similarity operators for queries as we cannot assume that all users will agree on exactly the same schema and value representations and ...
  • D-FOAF - Security Aspects in Distributed User Management System 

    Grzonkowski, Slawomir; Gzella, Adam; Kruk, Sebastian Ryszard; Woroniecki, Tomasz (IEEE, 2005)
    The contemporary Internet offers various services ranging from electronic newspapers to on- line social networks. To authorize themselves, users have to register to on-line services. However, most of the ...
  • D-FOAF: Distributed Identity Management with Access Rights Delegation 

    Kruk, Sebastian Ryszard; Grzonkowski, Slawomir; Gzella, Adam; Woroniecki, Tomasz; Choi, Hee Chul (2006)
    WWW provides a large number of services, which often require identification of it¿s users. This has lead to the fact that today users have to maintain a large number of different credentials for different websites - ...
  • Data Portability with SIOC and FOAF 

    Bojars, Uldis; Passant, Alexandre; Breslin, John (2008)
    Data portability has become an important requirement on the Social Web. This paper describes how data and social network portability can be achieved by building upon existing Semantic Web developments such as SIOC and FOAF. ...
  • Decomposing Discussion Forums using User Roles 

    Chan, Jeffrey; Hayes, Conor (http://www.websci10.org, 2010)
    Discussion forums are a central part of Web 2.0 and Enterprise 2.0 infrastructures. The health and sustainability of forums is dependent on the information exchange behaviour of its members. Such behaviour needs to be ...
  • Developing a Dataset for Technology Structure Mining 

    QasemiZadeh, Behrang; Buitelaar, Paul; Monaghan, Fergal (IEEE, 2010)
    This paper describes steps that have been taken to construct a development dataset for the task of Technology Structure Mining. We have defined the proposed task as the process of mapping a scientific corpus into a ...
  • The Development of A Realistic Simulation Framework with OMNeT++ 

    Shu, Lei (IEEE, 2008)
    It is necessary to use simulation tools in the study of wireless network. The object-oriented modular discrete event network simulator, OMNeT++, can not only afford many network simulation but has strong GUI support and ...
  • 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 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 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, ...
  • 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 ...
