  • 2LIP: Filling the Gap between the Current and the Three-Dimensional Web 

    Jankowski, Jacek; Decker, Stefan (2009)
    In this article we present a novel approach, the 2-Layer Interface Paradigm (2LIP), for designing simple yet interactive 3D web applications, an attempt to marry advantages of 3D experience with the advantages of the ...
  • Accessing Cultural Heritage using the Web of Data 

    Jankowski, Jacek; Cobos, Yolanda; Hausenblas, Michael; Decker, Stefan (2009)
    Cultural Heritage (CH) is a vast domain, where sharing information is challenging. As a result, the global CH is distributed and heterogeneous. In this paper, we present the concept of the Web of Data as an approach to ...
  • ActiveRDF: Object-oriented semantic web programming 

    Oren, Eyal; Delbru, Renaud; Gerke, Sebastian; Haller, Armin; Decker, Stefan (Association for Computing Machinery, 2007)
    Object-oriented programming is the current mainstream programming paradigm but existing RDF APIs are mostly triple-oriented. Traditional techniques for bridging a similar gap between relational databases and object-oriented ...
  • Automatic Location of Services 

    Keller, Uwe; Polleres, Axel; Fensel, Dieter (2005)
    The automatic location of services that fulfill a given need is seen as a key step towards dynamic and scalable integration. In this paper we present a model for the automatic location of services that considers the static ...
  • The Boardscape: Creating a Super Social Network of Message Boards 

    Breslin, John; Bojars, Uldis (AAAI, 2007)
    A Web-based message board or forum is an online area where discussions are held by many Internet users on a variety of subjects. More recently, online social networks have been created for various purposes: job searching, ...
  • Building a Heterogeneous Network of Digital Libraries on the Semantic Web 

    Piotrowski, Piotr; Cygan, Mariusz; Kruk, Sebastian Ryszard; Westerski, Adam; Samp, Krystian; Decker, Stefan (2006)
    Ever since computer networks have become popular libraries tend to join into federations. Each federated digital library, apart from delivering discovery and navigation features within their own database allows users to ...
  • Building a Semantic Web Search Engine: Challenges and Solutions 

    Harth, Andreas; Hogan, Aidan; Umbrich, Jürgen; Decker, Stefan (2008)
    Current web search engines return links to documents for user-specified keywords queries. Users have to then manually trawl through lists of links and glean the required information from documents. In contrast, semantic ...
  • A Context Lifecycle For Web-Based Context Management Services 

    Hynes, Gearoid; Reynolds, Vinny; Hauswirth, Manfred (2009)
    During the development of context aware applications a con- text management component must traditionally be created. This task re- quires specialist context lifecycle management expertise and hence can be a significant ...
  • CORAAL - Towards Deep Exploitation of Textual Resources in Life Sciences 

    Novacek, Vit; Groza, Tudor; Handschuh, Siegfried (Springer Verlag, 2009)
    Prominent biomedical literature search tools like ScienceDirect, PubMed Central or MEDLINE allow for efficient retrieval of resources based on key words. Due to vast amounts of data available in life sciences, key word ...
  • 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 ...
  • 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. ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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. ...
  • 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 ...
