    • Slicepedia: Towards Long-Tail Resource Production through Open Corpus Reuse 

      LAWLESS, SEAMUS (Springer, 2012)
      The production of resources supporting the needs of Adaptive Hypermedia Systems (AHS) is labor-intensive. As a result, content production is focused upon meeting the needs of resources with higher demand, which limits the ...

    • Web Search Personalisation Using Social Data 

      LAWLESS, SEAMUS; ZHOU, DONG; WADE, VINCENT (2012)
      Web search that utilizes social tagging data suffers from an extreme example of the vocabulary mismatch problem encountered in traditional Information Retrieval (IR). This is due to the personalized, unrestricted vocabulary ...

    • User Needs for Enhanced Engagement with Cultural Heritage Collections 

      Lawless, Seamus; Sweetnam, Mark; O Siochru, Micheal (2012)
      This paper presents research carried out in order to elicit user needs for the design and development of a digital library and research platform intended to enhance user engagement with cultural heritage collections. It ...

    • Slicepedia: Providing Customized Reuse of Open-Web Resources for Adaptive Hypermedia 

      LAWLESS, SEAMUS; LEVACHER, KILLIAN; WADE, VINCENT (2012)
      A key advantage of Adaptive Hypermedia Systems(AHS) is their ability to re-sequence and reintegrate content to satisfy particular user needs. However, this can require large volumes of content, with appropriate ...

    • Evaluation of a Domain-Aware Approach to User Model Interoperability 

      WALSH, EDMOND; WADE, VINCENT PATRICK; WALSH, EDDIE; O'CONNOR, ALEXANDER (2012)

    • Dynamic Contextual Usage Metadata for Learning Resource Reuse in Adaptive Environments 

      WADE, VINCENT PATRICK; WALSH, EDDIE; CONLAN, OWEN; RAFTER, RACHAEL (2011)
      Drawing on the experiences and context of others who have already used a particular resource can greatly facili- tate that resource?s reuse. Such reuse is essential when the resources in question are digital learning assets, ...

    • The non-verbal structure of patient case discussions in multidisciplinary medical team meetings 

      LUZ, SATURNINO (2012)
      Meeting analysis has a long theoretical tradition in social psychology, with established practical rami?cations in computer science, especially in computer supported cooperative work. More recently, a good deal of research ...

    • Cross-cultural assessment of automatically generated multimodal referring expressions in a virtual world 

      LUZ, SATURNINO (2012)
      This paper presents an assessment of automatically generated multimodal referring expressions as produced by embodied conversational agents in a virtual world. The algorithm used for this purpose employs general principles ...

    • A Universal Clinical Decision Support System using semantic web services 

      HEDERMAN, LUCY MARY; KHAN, HASEEB AHMAD (2012)
      In this paper we propose the use of semantic web services to achieve a universal clinical decision support system (CDSS). Our goal is to develop a semi-automated approach to discover, select and compose CDSSs available as ...

    • Quality Estimation: an experimental study using unsupervised similarity measures 

      VOGEL, CARL (The Association for Computational Linguistics (ACL), 2012)
      We present the approach we took for our participation to the WMT12 Quality Estimation Shared Task: our main goal is to achieve reasonably good results without appeal to supervised learning. We have used various similarity ...

    • A protected LR-PON deployment for the UK 

      Ruffini, Marco (2011)

    • Skinning with Dual Quaternions 

      Kavan, Ladislav; Collins, Steven; O'Sullivan, Carol; COLLINS, STEVEN (2007)
      Skinning of skeletally deformable models is extensively used for real-time animation of characters, creatures and similar objects. The standard solution, linear blend skinning, has some serious drawbacks that require artist ...

    • Geopostors: A Real-Time Geometry/Impostor Crowd Rendering System: 

      DOBBYN, SIMON; O'SULLIVAN, ANN CAROL; Hamill, David; O'Conor, keith (ACM Press, 2005)
      The simulation of large crowds of humans is important in many fi elds of computer graphics, including real-time applications such as games, as they can breathe life into otherwise static scenes and enhance believability. ...

    • Collisions and Attention 

      O'SULLIVAN, ANN CAROL (2005)
      Attention is an important factor in the perception of static and dynamic scenes, which should, therefore, be taken into account when creating graphical images and animation. Recently, researchers have recognized this fact ...

    • Collisions and attention 

      O'SULLIVAN, ANN CAROL; Lee, Richard (ACM Press, 2004)

    • Sphere-tree construction using dynamic medial axis approximation. 

      BRADSHAW, GARETH; O'SULLIVAN, CAROL (ACM, 2002)
      Collision handling is very computationally expensive, especially in large scale interactive animations. Hierarchical object representations play an important role in performing ef?cient collision handling. Many different ...

    • Smooth Movers: Perceptually Guided Human Motion Simulation 

      MCDONNELL, RACHEL; NEWELL, FIONA; O'SULLIVAN, CAROL (ACM Press, 2007)
      To animate a character, a number of poses are displayed in quick succession in order to create the illusion of motion. For most real-time applications, such as games, the pose update rate is largely constrained by the ...

    • Real-time Collision Detection and Response using Sphere-trees 

      O'SULLIVAN, CAROL; DINGLIANA, JOHN (1999)
      In this paper we address the problem of collision detection and response in real-time animation systems. We describe an approach, which approximates objects using sphere-trees, and uses an interruptible detection algorithm ...
