  • 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 ...
  • 3DWiki: The 3D Wiki Engine 

    Cobos, Yolanda; McDaniel, Bill; Decker, Stefan (2009)
    We demonstrate one of the potential paths of the evolution of wiki engines towards Web 3.0. We introduce 3dWiki - the 3D wiki engine, which was built according to 2-Layer Interface Paradigm (2LIP). It was developed ...
  • 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 ...
  • Annotation and Navigation in Semantic Wikis 

    Oren, Eyal; Delbru, Renaud; Möller, Knud; Handschuh, Siegfried (2006)
    Semantic Wikis allow users to semantically annotate their Wiki content. The particular annotations can differ in expressive power, simplicity, and meaning. We present an elaborate conceptual model for semantic annotations, ...
  • Approximating Query Completeness by Predicting the Number of Answers in DHT-based Web Applications 

    Karnstedt, Marcel; Hauswirth, Manfred; Sapkota, Brahmananda (2008)
  • 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, ...
  • Browsing Linked Data with Fenfire 

    Hastrup, Tuukka; Cyganiak, Richard; Bojars, Uldis (2008)
    A wealth of information has recently become available as browsable RDF data on the Web, but the selection of client applications to interact with this Linked Data remains limited. We show how to browse Linked Data with ...
  • 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 ...
  • Converging Web and Desktop Data with Konduit 

    Dragan, Laura; Möller, Knud; Handschuh, Siegfried; Ambrus, Oszkar (2009)
    In this paper we present Konduit, a desktop-based platform for visual scripting with RDF data. Based on the idea of the semantic desktop, non-technical users can create, manipulate and mash-up RDF data with Konduit, and ...
  • A Conversation-oriented language for B2B integration based on Semantic Web Services 

    Gomez, Juan Miguel; Haller, Armin; Bussler, Christoph (2005)
    Establishing conversations in a B2B environment has significantly eased since the advent of standards such as RosettaNet and ebXML. These standardisation efforts have maintained some flexibility in defining interactions ...
  • 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 - Distributed Identity Management based on Social Networks 

    Kruk, Sebastian Ryszard; Gzella, Adam; Grzonkowski, Slawomir (2006)
