    • 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 ...
    • SAFE: Policy Aware SPARQL Query Federation Over RDF Data Cubes 

      Yasar Khan and Muhammad Saleem and Aftab Iqbal and Muntazir Mehdi and Aidan Hogan and Axel-Cyrille Ngonga Ngomo and Stefan Decker and Ratnesh Sahay (2014)
    • SAFE: SPARQL federation over RDF data cubes with access control 

      Khan, Yasar; Saleem, Muhammad; Mehdi, Muntazir; Hogan, Aidan; Mehmood, Qaiser; Rebholz-Schuhmann, Dietrich; Sahay, Ratnesh (BioMed Central, 2017-02-01)
      Several query federation engines have been proposed for accessing public Linked Open Data sources. However, in many domains, resources are sensitive and access to these resources is tightly controlled by stakeholders; ...
    • 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 ...
    • A Scenario-View Based Approach to Analyze External Behavior of Web Services for Supporting Mediated Service Interactions 

      Zhou, ZhangBing; Bhiri, Sami; Shu, Lei; Vasiliu, Laurentiu; Hauswirth, Manfred (IEEE, 2008)
      Web service interactions have triggered the initiative to identify and solve mismatches from a behavioral aspect. Current approaches are limited since they mainly focus on control-flow but largely ignore data-flow. In this ...
    • SCOVO: Using Statistics on the Web of Data 

      Hausenblas, Michael (2009)
      Statistical data is present everywhere from governmental bodies to economics, from life-science to industry. With the rise of the Web of Data, the need for sharing, accessing, and using this data has entered a new stage. ...
    • Self-Surveillance 

      Schneider, Jodi (2009-07)
    • SemanTex: semantic text exploration using document links implied by conceptual networks extracted from the texts 

      Aldarra, Suad; Muñoz, Emir; Vandenbussche, Pierre-Yves; Nováček, Vít (ACMCEUR-WS.org, 2014)
      Despite of advances in digital document processing, exploration of implicit relationships within large amounts of textual resources can still be daunting. This is partly due to the ‘black-box’ nature of most current ...
    • A semantic framework for modelling quotes in email conversations 

      Passant, Alexandre; Zimmermann, Antoine; Schneider, Jodi; Breslin, John G. (2010)
      Quoting is a common practice in online conversations, notably in email discussions and bulletin boards. Despite many applications that offer special functionalities to handle them, there is no agreement on how to semantically ...
    • Semantic relation classification: task formalisation and refinement
