  • The 2LIP Model and Its Implementations 

    Jankowski, Jacek; Decker, Stefan (2009)
  • 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 ...
  • An Annotation-based Access Control Model and Tools for Collaborative Information Spaces 

    Nasirifard, Peyman; Peristeras, Vassilios; Decker, Stefan (2008)
    We present an Annotation-Based Access Control model supported by a Collaboration Vocabulary (CoVoc) as a more flexible and user-centric access control approach in social platforms and shared workspaces. We present ...
  • Applying DAC Principles to the RDF Graph Data Model 

    Kirrane, Sabrina; Mileo, Alessandra; Decker, Stefan (2013)
    In this paper we examine how Discretionary Access Control principles, that have been successfully applied to relational and XML data, can be applied to the Resource Description Framework (RDF) graph data model. The ...
  • Architecture of Linked Data Applications 

    Heitmann, Benjamin; Cyganiak, Richard; Hayes, Conor; Decker, Stefan (CRC Press (Taylor & Francis), 2014)
    In this chapter, we first perform an empirical survey of RDF-based applications over most of the past decade, from 2003 to 2009. As the Linked Data principles where introduced in 2006, this allows us to describe the current ...
  • 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 ...
  • Cataloguing and Linking Life Sciences LOD 

    Hasnain, Ali; Fox, Ronan; Deus, Helena F.; Decker, Stefan (2012)
    The Life Sciences Linked Open Data (LSLOD) Cloud is currently comprised of multiple datasets that add high value to biomedical research. The ability to navigate through these datasets in order to derive and discover new ...
  • Demo: Visual Programming for the Semantic Desktop with Konduit 

    Möller, Knud; Handschuh, Siegfried; Decker, Stefan (2008)
    In this demo description, we present Konduit, a desktop-based platform for visual programming with RDF data. Based on the idea of the semantic desktop, non-technical users can create, manipulate and mash-up RDF data with ...
  • 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 ...
  • Enabling Trust and Privacy on the Social Web 

    Passant, Alexandre; Hausenblas, Michael; Polleres, Axel; Decker, Stefan (2009)
  • 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 ...
  • 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. ...
  • Extracting and Utilizing Social Networks from Log Files of Shared Workspaces 

    Nasirifard, Peyman; Peristeras, Vassilios; Hayes, Conor; Decker, Stefan (Springer, 2009)
    Log files of online shared workspaces contain rich information that can be further analyzed. In this paper, log-file information is used to extract object-centric and user-centric social networks. The object-centric social ...
  • Eye of the Tiger 

    Novacek, Vit; Groza, Tudor; Handschuh, Siegfried; Decker, Stefan (2009)
  • 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 ...
