    • 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 ...

    • An abstract framework for modeling argumentation in virtual communities 

      Groza, Tudor; Handschuh, Siegfried; Breslin, John G.; Decker, Stefan (IGI Global, 2009)
      Classic argumentative discussions can be found in a variety of domains from traditional scientific publishing to today’s modern social software. An interactive argumentative discussion usually consists of an initial ...

    • 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: embedding semantic web data into object-oriented languages 

      Oren, Eyal; Heitmann, Benjamin; Decker, Stefan (Elsevier BV, 2008-09-01)

    • 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 empirical survey of linked data conformance 

      Hogan, Aidan; Umbrich, Jürgen; Harth, Andreas; Cyganiak, Richard; Polleres, Axel; Decker, Stefan (Elsevier BV, 2012-07-01)

    • 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 ...

    • Biofed: federated query processing over life sciences linked open data 

      Hasnain, Ali; Mehmood, Qaiser; Sana e Zainab, Syeda; Saleem, Muhammad; Warren, Claude; Zehra, Durre; Decker, Stefan; Rebholz-Schuhmann, Dietrich (Springer Nature, 2017-03-15)
      Background: Biomedical data, e. g. from knowledge bases and ontologies, is increasingly made available following open linked data principles, at best as RDF triple data. This is a necessary step towards unified access to ...

    • 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 ...

    • The Design and Evaluation of Graphical Radial Menus 

      Samp, Krystian (2011-12-05)
      Graphical menus provide slow performance and yet users often try to select menu commands as fast as possible. Shortcut techniques that enable users to by-pass selections from a graphical menu are fast, but are not the ...
