    • Applying DAC Principles to the RDF Graph Data Model 

      Kirrane, Sabrina; Mileo, Alessandra; Decker, Stefan (2013)
      In this paper we examine how Discretionary Access Control principles, that have been successfully applied to relational and XML data, can be applied to the Resource Description Framework (RDF) graph data model. The ...
    • DRETa: extracting RDF from wikitables 

      Muñoz, Emir; Hogan, Aidan; Mileo, Alessandra (CEUR-WS.org, 2013)
      Tables are widely used in Wikipedia articles to display relational information - they are inherently concise and information rich. However, aside from info-boxe s, there are no automatic methods to exploit the integrated ...
    • A Logic Programming approach for Access Control over RDF 

      Lopes, Nuno; Kirrane, Sabrina; Mileo, Alessandra; Zimmermann, Antoine; Polleres, Axel (International Conference on Logic Programming (ICLP), 2012)
      The Resource Description Framework (RDF) is an interoperable data representation format suitable for interchange and integration of data, especially in Open Data contexts. However, RDF is also becoming increasingly attractive ...
    • 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, ...
    • Semantically Interlinked Notification System for Ubiquitous Presence Management 

      Mehmood, Qaiser; Ali, Muhammad Intizar; Mileo, Alessandra (Springer, 2013)
      Presence based notification systems play a pivotal role in any collaborative working environment by providing near real time information about the status, locality and presence of the collaborators. Instant Messaging (IM) ...
    • Triplifying Wikipedia's tables 

      Muñoz, Emir; Hogan, Aidan; Mileo, Alessandra (CEUR-WS.org, 2013)
      We are currently investigating methods to triplify the content of Wikipedia's tables. We propose that existing knowledge-bases can be leveraged to semi-automatically extract high-quality facts (in the form of RDF triples) ...
    • Update Semantics for Interoperability among XML, RDF and RDB - A Case Study of Semantic Presence in CISCO's Unified Presence Systems 

      Ali, Muhammad Intizar; Lopes, Nuno; Mileo, Alessandra (Springer, 2013)
      XSPARQL is a transformation and querying language that provides an integrated access over heterogeneous data sources on the fly. It is an extension of XQuery which supports a subset of SPARQL and SQL to provide unified ...
    • Using linked data to mine RDF from wikipedia's tables 

      Muñoz, Emir; Hogan, Aidan; Mileo, Alessandra (ACM, 2014)
      The tables embedded in Wikipedia articles contain rich, semi-structured encyclopaedic content. However, the cumulative content of these tables cannot be queried against. We thus propose methods to recover the semantics of ...
    • XSPARQL-Viz: A Mashup-Based Visual Query Editor for XSPARQL 

      Gillani, Syed Zeeshan Haider; Ali, Muhammad Intizar; Mileo, Alessandra (Springer, 2013)
      XSPARQL is a query language which facilitates query, integration and transformation between XML and RDF data formats. Although XSPARQL supports semantic data integration by providing uniform access over XML and RDF, but ...
