      KELLY, STEPHEN (Trinity College Dublin, 2016)
      With the advent of the internet and digitisation of news and books, the volume of unstructured text has increased dramatically in recent years. This deluge of information is set to grow and come from new and unconventional ...

    • The Non-invasive Personalisation of Educational Video Games 

      PEIRCE, NEIL (Trinity College DublinTrinity College Dublin, 2013)
      Educational video games present a progressive approach to technology enhanced learning that offer intrinsically rewarding experiences, high interactivity, an environment with low-risk of failure, and the freedom and ...

    • OM2R : semantic documentation of ontology mapping lifecycle to support retrieval and reuse of ontology mappings 

      Thomas, Hendrik (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)
      Ontology mappings are of critical importance for the Linked Data and the Semantic Web communities as they can help to mitigate the effects of heterogeneities, which are a major obstacle to the promise of interoperability ...

    • On the Virtualization of Wireless Links 

      van de Belt, Jonathan
      This thesis is concerned with the virtualization of wireless links. Initially, the sole aim of this thesis was to investigate the virtualization of wireless networks. However, soon after first investigating this topic ...

    • On-demand multimedia server clustering using dynamic content replication 

      Dukes, Jonathan (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2004)
