      Sudharsan, Bharath; Patel, Pankesh; Breslin, John G.; Ali, Muhammad Intizar (Institute of Electrical and Electronics Engineers (IEEE), 2021-05-25)
      With the introduction of edge analytics, IoT devices are becoming smart and ready for AI applications. A few modern ML frameworks are focusing on the generation of small-size ML models (often in kBs) that can directly be ...
    • Uncovering semantic bias in neural network models using a knowledge graph 

      Nikolov, Andriy; d'Aquin, Mathieu (ACM, 2020-10-19)
      While neural networks models have shown impressive performance in many NLP tasks, lack of interpretability is often seen as a disadvantage. Individual relevance scores assigned by post-hoc explanation methods are not ...
    • Understanding Contributor to Developer Turnover Patterns in OSS Projects: A Case Study of Apache Projects 

      Iqbal, Aftab (Hindawi Publishing Corporation, 2014-01-19)
      OSS projects are dynamic in nature. Developers contribute to a project for a certain period of time and later leave the project or join other projects of high interest. Hence, the OSS community always welcomes members who ...
    • Understanding Linked Open Data as a Web-Scale Database 

      Hausenblas, Michael; Karnstedt, Marcel (2010)
      While Linked Open Data (LOD) has gained much attention in the recent years, requirements and the challenges concerning its usage from a database perspective are lacking. We argue that such a perspective is crucial for ...
    • Understanding my city through dashboards. How hard can it be?

      This paper describes research into how current city dashboards support users' sensemaking processes. It uses criteria identified in previous research concerning visualisation and applies these to a number of city dashboards ...
    • Understanding the Maturity of Sustainable ICT 

      Curry, Edward; Donnellan, Brian (Springer, 2012)
      Sustainable ICT (SICT) can develop solutions that offer benefits both internally in IT and across the extended enterprise. However, because the field is new and evolving, few guidelines and best practices are available. ...
    • UniStore: Querying a DHT-based Universal Storage 

      Karnstedt, Marcel; Hauswirth, Manfred (2007)
      In recent time, the idea of collecting and combining large public data sets and services became more and more popular. The special characteristics of such systems and the requirements of the participants demand for ...
    • Unsupervised Graph-Based Topic Labelling using DBpedia 

      Hulpus, Ioana; Hayes, Conor; Karnstedt, Marcel; Greene, Derek (2013)
      Automated topic labelling brings benefits for users aiming at analysing and understanding document collections, as well as for search engines targetting at the linkage between groups of words and their inherent topics. ...
    • Unsupervised learning for understanding student achievement in a distance learning setting 

      Liu, Shuangyan; d’Aquin, Mathieu (IEEE, 2017-04-25)
      Many factors could affect the achievement of students in distance learning settings. Internal factors such as age, gender, previous education level and engagement in online learning activities can play an important role ...
    • Unsupervised method to analyze playing styles of EPL teams using ball possession-position data 

      Verma, Pranav; Sudharsan, Bharath; Chakravarthi, Bharathi Raja; O'Riordan, Colm; Hill, Seamus (IEEE, 2020-03-06)
      In the English Premier League (EPL) matches, a network of advanced systems gathers sports data in real-time to build a possession-position dataset. In this work, data fields from the sophisticated raw possession-position ...
    • 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 domain-specific and collaborative resources for term translation 

      Arcan, Mihael; Buitelaar, Paul; Federmann, Christian (Association for Computational Linguistics, 2012-07)
      In this article we investigate the translation of terms from English into German and vice versa in the isolation of an ontology vocabulary. For this study we built new domainspecific resources from the translation ...
    • Using drug similarities for discovery of possible adverse reactions 

      Muñoz, Emir; Nováček, Vít; Vandenbussche, Pierre-Yves (AMIA, 2017-02-10)
      We propose a new computational method for discovery of possible adverse drug reactions. The method consists of two key steps. First we use openly available resources to semi-automatically compile a consolidated data set ...
    • 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 ...
