  • 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 ...
  • 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, ...
  • Extending Community Ontology Using Automatically Generated Suggestions 

    Novacek, Vit; Dabrowski, Maciej; Kruk, Sebastian Ryszard; Handschuh, Siegfried (AAAI Press, 2007)
    In this paper we propose an ontology (formal knowledge base) creation methodology based on integrating external ontologies into the one developed by a community of the do- main experts. We present the MarcOntX agent, a ...
  • 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 ...
  • Imprecise Empirical Ontology Refinement: Application to Taxonomy Acquisition 

    Novacek, Vit (INSTICC, 2007)
    The significance of uncertainty representation has become obvious in the Semantic Web community recently. This paper presents new results of our research on uncertainty incorporation into ontologies created automatically ...
  • Leveraging Ontologies, Context and Social Networks to Automate Photo Annotation 

    Monaghan, Fergal; O'Sullivan, David (Springer, 2007)
    This paper presents an approach to semi-automate photo an- notation. Instead of using content-recognition techniques this approach leverages context information available at the scene of the photo such as time and location ...
  • On the Ostensibly Silent 'W' in OWL 2 RL 

    Hogan, Aidan; Decker, Stefan (Springer, 2009)
    In this paper, we discuss the draft OWL 2 RL proable from the perspective of applying the constituent rules over Web data. In particular, borrowing from previous work, we discuss (i) optimisations based on a separation ...
  • Ontologising Interaction Behavior for Service-Oriented Enterprise Healthcare Integration 

    Sahay, Ratnesh; Fox, Ronan; Hauswirth, Manfred (IEEE, 2008)
  • Quantified equilibrium logic and hybrid rules 

    Polleres, Axel (Springer, 2007)
    In the ongoing discussion about combining rules and Ontologies on the Semantic Web a recurring issue is how to combine first-order classical logic with nonmonotonic rule languages. Whereas several modular approaches to de- ...
  • SAOR: Authoritative Reasoning for the Web 

    Hogan, Aidan; Harth, Andreas; Polleres, Axel (Springer, 2008)
    In this paper we discuss the challenges of performing reasoning on large scale RDF datasets from the Web. We discuss issues and practical solutions relating to reasoning over web data using a rule-based approach to ...
  • Semantic Versioning Manager: Integrating SemVersion in Protégé 

    Groza, Tudor; Handschuh, Siegfried (2006)
    Knowledge domains and their semantic representations via ontologies are typically subject to change in practical applications. Additionally, engineering of ontologies often takes place in distributed settings where multiple ...
