  • On lexicographical networks 

    Ahmadi, Sina; Arcan, Mihael; McCrae, John (NUI Galway, 2018-12-06)
    In this study, we analyze various aspects of lexicographical networks. We would like to answer our research questions of what are the characteristics of the lexicographical networks? In addition to the existing notions of ...
  • Open social data crime analytics 

    Ihsan, Ullah,; Lane, Caoilfhionn; Drury, Brett; Mellotte, Marc; Madden, Michael G. (IJCAI 17 Melbourne, 2017-07-20)
    Crime is under-reported. Reporting crime requires the victim to complete a number of administrative obligations. These obligations, as well as the nature of the crime, may create an inertia that discourages the reporting ...
  • Passive diagnosis incorporating the PHQ-4 for depression and anxiety 

    Delahunty, Fionn; Johansson, Robert; Mihael, Arcan (NUI Galway, 2019)
    Depression and anxiety are the two most prevalent mental health disorders worldwide, impacting the lives of millions of people each year. In this work, we develop and evaluate a multilabel, multidimensional deep neural ...
  • 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 ...
  • 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 ...
  • Podcast Pinpointer: A Multimedia Semantic Web Application 

    Hogan, Aidan; Harth, Andreas; Breslin, John (IEEE, 2005)
    In late 2004, a new method of publishing multimedia broadcasts on the Internet became popular called `Podcasting¿. Podcasting incorporates existing feed description formats, namely RSS 2.0, to ...
  • Processing ontology alignments with SPARQL 

    Polleres, Axel (IEEE, 2008)
    Solving problems raised by heterogeneous ontologies can be achieved by matching the ontologies and processing the resulting alignments. This is typical of data mediation in which the data must be translated from one ...
  • Processing ontology alignments with SPARQL 

    Polleres, Axel (IEEE Computer Society, 2008)
  • 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 ...
  • Relaxing the Basic KR&R Principles to Meet the Emergent Semantic Web 

    Nováček, Vít (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.
  • Robot-assisted care for elderly with dementia: is there a potential for genuine end-user empowerment? 

    Felzmann, Heike; Murphy, Kathy; Casey, Dympna; Beyan, Oya (2015)
  • The role of negative results for choosing an evaluation approach - a recommender systems case study 

    Heitmann, Benjamin; Hayes, Conor (CEUR Workshop Proceedings, 2015-06-01)
    We describe a case study, which shows how important negative results are in uncovering biased evaluation methodologies. Our re- search question is how to compare a recommender algorithm that uses an RDF graph to a ...
  • 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 ...
  • 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 ...
  • Semantic relation classification: task formalisation and refinement 

    Silva, Vivian S.; Hürliman, Manuela; Davis, Brian; Handschuh, Siegfried; Freitas, André (Association for Computational Linguistics, 2016-12-12)
    The identification of semantic relations between terms within texts is a fundamental task in Natural Language Processing which can support applications requiring a lightweight semantic interpretation model. Currently, ...
  • Semantic Social Collaborative Filtering with FOAFRealm 

    Kruk, Sebastian Ryszard; Decker, Stefan (2005)
    The most popular collaborative filtering implementations require either a critical mass of referenced resources and a lot of active users. Other solutions are based on finding a referral with an expertise on the given ...
  • Semantic Web Services enabled B2B Integration 

    Kotinurmi, Paavo; Vitvar, Tomas; Haller, Armin (2006)
    The use of Semantic Web Service (SWS) technologies have been suggested to enable more dynamic B2B integration of heterogeneous systems and partners. We present our approach to accomplish dynamic B2B integrations based on ...
  • Semi-automatic Integration of Learned Ontologies into a Collaborative Framework 

    Nováček, Vít; Handschuh, Siegfried (2007)
    The paper presents a novel ontology lifecycle scenario that explicitly takes the dynamics and data-intensiveness of real world applications into account. Changing and growing knowledge is handled by semi-automatic ...
  • SIOC: Content Exchange and Semantic Interoperability Between Social Networks 

    Breslin, John; Bojars, Uldis; Passant, Alexandre; Fernández, Sergio; Decker, Stefan (2009)
    This paper describes work performed during the last few years in the context of the SIOC project in order to model social data on the Web using Semantic Web technologies. We will give an overview of the SIOC model, ...
  • Social Networking Portals: An Overview and Evaluation 

    O'Murchu, Ina; Breslin, John; Decker, Stefan (2004)
    Next generation communication on the Internet changes the way we interact with the complexity of the information load on the World Wide Web. Web portals act as gateways to resources and a multitude of services on the ...
