  • Protect Your RDF Data! 

    Kirrane, Sabrina; Lopes, Nuno; Mileo, Alessandra; Decker, Stefan (2012)
    The explosion of digital content and the heterogeneity of enterprise content sources have pushed existing data integration solutions to their boundaries. Although RDF can be used as a representation format for integrated data, ...
  • 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 ...
  • 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 ...
  • Quality-driven resource-adaptive data stream mining? 

    Karnstedt, Marcel (IEEE / ACM, 2011-01)
    Data streams have become ubiquitous in recent years and are handled on a variety of platforms, ranging from dedicated high-end servers to battery-powered mobile sensors. Data stream processing is therefore required to work ...
  • 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- ...
  • Rapid Competence Development in Serious Games Using Case-Based Reasoning and Threshold Concepts 

    Hulpus, Ioana; Fradinho, Manuel; Hayes, Conor (2010)
    A major challenge in todays fast pace world is the acquisition of competence in a timely and efficient manner, whilst keeping the individual highly motivated. This paper presents a novel based on the use of serious games ...
  • ReConRank: A Scalable Ranking Method for Semantic Web Data with Context 

    Hogan, Aidan; Harth, Andreas; Decker, Stefan (2006)
    We present an approach that adapts the well-known PageRank/HITS algorithms to Semantic Web data. Our method combines ranks from the RDF graph with ranks from the context graph, i.e. data sources and their linkage. We present ...
  • Reconstruction of Threaded Conversations in Online Discussion Forums 

    Aumayr, Erik; Jeffrey, Chan; Hayes, Conor (Fifth International AAAI Conference on Weblogs and Social Media, 2011-07-18)
    [no abstract available]
  • Relaxing the Basic KR&R Principles to Meet the Emergent Semantic Web 

    Novacek, Vit (CEUR-WS, 2008)
    The paper argues for an alternative, empirical (instead of analytical) approach to a Semantic Web-ready KR&R, motivated by the so far largely untackled need for a feasible emergent content processing.
  • The Role of Community-Driven Data Curation for Enterprises 

    Curry, Edward; Freitas, Andre; O'Ríain, Seán (Springer US, 2010)
    With increased utilization of data within their operational and strategic processes, enterprises need to ensure data quality and accuracy. Data curation is a process that can ensure the quality of data and its fitness ...
  • A rule system for querying persistent RDFS data 

    Krennwallner, Thomas; Martello, Alessandra; Polleres, Axel (2009)
    We present GiaBATA, a system for storing, aggregating, and querying Semantic Web data, based on declarative logic programming technology, namely on the dlvhex system, which allows us to implement a fully SPARQL compliant ...
  • S3QL: A distributed domain specific language for controlled semantic integration of life sciences data 

    Deus, Helena (2011)
    Background The value and usefulness of data increases when it is explicitly interlinked with related data. This is the core principle of Linked Data. For life sciences researchers, harnessing the power of Linked Data ...
  • SAGE: An Ambient Intelligent Framework for Manufacturing 

    Hynes, Gearoid; Monaghan, Fergal; Thai, VinhTuan; O'Sullivan, David (2006)
    To profit in today¿s market, small manufacturers must be efficient and agile to minimise cost and to meet variable market demand. This paper discusses an envisaged Semantic, Ambient, Generic and Extensible framework ...
  • SALT: Enriching LATEX with Semantic Annotations 

    Groza, Tudor; Kim, Hak Lae; Handschuh, Siegfried (2006)
    With the emergence of the SemanticWeb, encapsulating annotations and metadata into scientific documents became a widely used practice. But in the same time, we observed the lack of well established standard tools supporting ...
  • SALT: Semantically Annotated LATEX 

    Groza, Tudor; Handschuh, Siegfried; Kim, Hak Lae (2006)
    Machine-understandable data constitutes the basis for the Semantic Desktop. We provide in this paper means to author and annotate Semantic Documents on the Desktop. In our approach, the PDF file format is the basis for ...
  • 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 ...
  • Scalable Authoritative OWL Reasoning for the Web 

    Hogan, Aidan; Harth, Andreas; Polleres, Axel (2009)
  • Scalable Authoritative OWL Reasoning on a Billion Triples 

    Hogan, Aidan; Harth, Andreas; Polleres, Axel (2008)
    In this paper we present a scalable algorithm for performing a subset of OWL reasoning over web data using a rule-based approach to forward-chaining; in particular, we identify the problem of ontology hijacking: new ...
  • Scalable web reasoning using logic programming techniques 

    Lukácsy, Gergely (2009)
    One of the key issues for the uptake of the Semantic Web idea is the availability of reasoning techniques that are usable on a large scale and that offer rich modeling capabilities by providing comprehensive coverage of ...
