  • 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, ...
  • 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. ...
  • Handling heterogeneity in RosettaNet messages 

    Haller, Armin; Kotinurmi, Paavo; Vitvar, Tomas; Oren, Eyal (2007)
    We present a semantic B2B gateway based on the WSMX se- mantic Service-Oriented Architecture to tackle heterogeneities in RosettaNet messages. We develop a rich RosettaNet ontology and use the axiomatised knowledge and ...
  • Leveraging existing web frameworks for a SIOC explorer to browse online social communities 

    Heitmann, Benjamin; Oren, Eyal (2007)
    Since online SemanticWeb applications are based on existing Web infrastructure, developing these applications could leverage experiences with and infrastructure of existing frameworks. These frameworks need to be extended ...
  • A lookup index for Semantic Web resources 

    Oren, Eyal; Tummarello, Giovanni (2007)
    Developers of Semantic Web applications face a challenge with respect to the decentralised publication model: where to find statements about encountered resources. The ¿linked data¿ approach, which mandates that resource ...
  • m3pl: A Work-FLOWS ontology extension to extract choreography interfaces 

    Haller, Armin; Oren, Eyal (2006)
    Cross-organisational interoperability is a key issue for success in B2B e-commerce applications. To achieve this interoperability, choreography descriptions are necessary that describe how the business partners can cooperate. ...
  • A Prototype to Explore Content and Context on Social Community Sites 

    Bojars, Uldis; Heitmann, Benjamin; Oren, Eyal (2007)
    The SIOC Ontology can be used to express information from the online community sites in a machine readable form using RDF. This rich data structure allows us to easily analyse and extract social relations from these ...
  • Semantic Wikis for Personal Knowledge Management 

    Oren, Eyal; Breslin, John; Decker, Stefan (Springer, 2006)
    Wikis are becoming popular knowledge management tools. Analysing knowledge management requirements, we observe that wikis do not fully support structured search and knowledge reuse. We show how Semantic wikis address the ...
  • Simple algorithms for predicate suggestions using similarity and co-occurrence 

    Oren, Eyal; Gerke, Sebastian; Decker, Stefan (Association for Computing Machinery, 2007)
    When creating Semantic Web data, users have to make a critical choice for a vocabulary: only through shared vocabularies can meaning be established. A centralised policy prevents terminology divergence but would restrict ...
  • Sindice.com: Weaving the open linked data 

    Tummarello, Giovanni; Delbru, Renaud; Oren, Eyal (2007)
    Developers of SemanticWeb applications face a challenge with respect to the decentralised publication model: where to find statements about encountered resources. The linked data" approach, which man- dates that resource ...
  • Towards a reference architecture for Semantic Web applications 

    Heitmann, Benjamin; Hayes, Conor; Oren, Eyal (2009)
    The Semantic Web currently has two complementary architectural approaches: ¿Bottom-up¿ emergent best practices by the community and ¿top-down¿ prescriptive standards by standards bodies, leaving a gap regarding the concrete ...
