    • 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 ...
    • Modeling services for the semantic grid 

      Polleres, Axel; Fensel, Dieter (2005)
    • MultiBeeBrowse Accessible Browsing on Unstructured Metadata 

      Kruk, Sebastian Ryszard; Gzella, Adam; Czaja, Filip; Bultrowicz, Wladyslaw; Kruk, Ewelina (Springer, 2007)
      Growing abundance of information on the Internet, especially the Next Generation Internet, poses even more challenges on more efficient information management; hence it has brought attention of the researchers to the faceted ...
    • On the efficiency of joining group patterns in SPARQL queries 

      Sierra, Javier; Polleres, Axel (2010)
      In SPARQL, conjunctive queries are expressed by using shared variables across sets of triple patterns, also called basic graph patterns. Based on this characterization, basic graph patterns in a SPARQL query can be ...
    • On the need of integrating social media channels and open source software repositories 

      Iqbal, Aftab; Decker, Stefan (IEEE, 2015)
      The growing interest in the usage of social media channels have attracted the open source software community to adopt an identity in order to disseminate project-related information to a wider audience. We foresee the need ...
    • 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)
    • OWL DL vs. OWL Flight: Conceptual Modeling and Reasoning for the Semantic Web 

      Polleres, Axel; Fensel, Dieter (2005)
      The Semantic Web languages RDFS and OWL have been around for some time now. However, the presence of these languages has not brought the breakthrough of the Semantic Web the creators of the languages had hoped for. OWL has ...
    • A Protégé Plug-in Development to Support the NEPOMUK Representational Language 

      Caires, Milena; Scerri, Simon; Handschuh, Siegfried (2007)
      In this document, we present the challenges faced to develop a plug-in for Protégé that supports requirements for the NEPOMUK1 Representational Language (NRL). NRL is a language built on top of RDF/S and ...
    • 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- ...
    • Querying web polystores 

      Khan, Ya; Zimmermann, Antoine; Jha, AlokKumar; Rebholz-Schuhmann, Dietrich; Sahay, Ratnesh (IEEE, 2017-12-11)
      The database, semantic web, and linked data communities have proposed solutions that federate queries over multiple data sources using a single data model. Nowadays, the data retrieval requirements originating from versatile ...
    • 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 ...
    • 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 European Patient Summaries based on Triple Space Computing 

      Foxvog, Doug (2006)
      Medical practice today still entails sorting through scattered information on a specific patient. Making things more difficult, the EU, in bringing its member states closer together, is encouraging people¿s mobility, and ...
    • Towards Intelligent web Services: Web Service Modeling Ontology (WSMO) 

      Polleres, Axel; Fensel, Dieter (Springer, 2005)

      Hayes, Conor (IAAA, 2007)
      The Web has experienced an exponential growth in the use of weblogs or blogs. Blog entries are generally organised using tags, informally defined labels which are increasingly being proposed as a `grassroots¿ answer to ...
    • Where is the News Breaking? Towards a Location-based Event Detection Framework for Journalists 

      Khare, Prashant; Heravi, Bahareh Rahmanzadeh (Springer, 2014)
       The rise of user-generated content (UCG) as a source of information in the journalistic lifecycle is driving the need for automated methods to detect, filter, contextualise and verify citizen reports of breaking news ...
