  • 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 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 ...
  • On The Way to The Web3D: The Applications of 2-Layer Interface Paradigm

    The use of the Internet for entertainment continues to grow. The success of rich media web portals, such as: YouTube, Flickr, or Google Maps proves that people look for more and more interactive experience on the Web. ...
  • On-the-Fly Adaptive Planning for Game-Based Learning 

    Hulpus, Ioana; Hayes, Conor (2010)
    In this paper, we present a model for competency development using serious games, which is underpinned by a hierarchical case-based planning strategy. In our model, a learner s objectives are addressed by retrieving a ...
  • On-the-fly generation of multidimensional data cubes for web of things 

    Sahay, Ratnesh; Derguech, Wassim; Curry, Edward (2013)
  • 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 ...
  • Path-based semantic relatedness on linked data and its use to word and entity disambiguation 

    Hulpus, Ioana; Prangnawarat, Narumol; Hayes, Conor (2015)
    Semantic relatedness and disambiguation are fundamental problems for linking text documents to the Web of Data. There are many approaches dealing with both problems but most of them rely on word or concept distribution ...
  • Performing Object Consolidation on the Semantic Web Data Graph 

    Hogan, Aidan; Harth, Andreas; Decker, Stefan (2007)
    An important aspect of Semantic Web technologies is the issue of identity and uniquely identifying resources, which is essential for integrating data across sources. Currently, there is poor agreement on the use of ...
  • Perk-dependent repression of miR-106b-25 cluster is required for ER stress-induced apoptosis 

    Gupta, Sanjeev; Read, D.E.; Deepti, A.; Cawley, K.; Gupta, A.; Oommen, D.; Samal, Afshin (2012)
    Activation of the unfolded protein response sensor PKR-like endoplasmic reticulum kinase (Perk) attenuates endoplasmic reticulum (ER) stress levels. Conversantly, if the damage is too severe and ER function cannot be ...
  • Personalized Question Answering: A Use Case for Business Analysis 

    Thai, VinhTuan; O'Riain, Sean; Davis, Brian; O'Sullivan, David (2006)
    In this paper, we introduce the Personalized Question Answering framework, which aims at addressing certain limitations of existing domain specific Question Answering systems. Current development efforts are ongoing to ...

  • Previewing Semantic Web Pipes 

    Phuoc, Danh Le; Polleres, Axel; Samwald, Matthias; Tummarello, Giovanni (Springer, 2008)
    In this demo we present a first implementation of Semantic Web Pipes, a powerful tool to build RDF-based mashups. Semantic Web pipes are defined in XML and when executed they fetch RDF graphs on the Web, operate on them, ...
  • Process Mediation Based on Triple Space Computing 

    Zhou, ZhangBing; Sapkota, Brahmananda; Cimpian, Emilia; Foxvog, Doug; Vasiliu, Laurentiu; Hauswirth, Manfred (Springer, 2008)
    Web services are inherently heterogeneous at both data and behavioral levels because of the nature of the Web, which is the main obstacle to the usability of Web services. The heterogeneity at a behavioral level is generally ...
