Mems Mobile Gis: A Spatially Enabled Fish Habitat Management System, Andrea Rizzini, Keith Gardiner, Michela Bertolotto, James Carswell

Conference papers

Spatially enabled computing can provide assistance to both web-based and mobile users by exploiting positional information and associated contextual knowledge. The Mobile Environmental Management System (MEMS) is a proof of concept prototype that has been developed in order to simplify administrative duties of biologists at the Department of Fisheries and Oceans (DFO), Canada. MEMS aims to deliver contextaware functionality aided by visualization, analysis and manipulation of spatial and attribute datasets. The resulting application delivers a set of functions and services that aids the DFO’s biologists in making everyday management decisions

Serious Gordon Using Serious Games To Teach Food Safety In The Kitchen, Brian Mac Namee, Pauline Rooney, Patrick Lindstrom, Andrew Ritchie, Frances Boylan, Greg Burke

Conference papers

This paper will describe the development of Serious Gordon, an interactive digital game developed to tech the basics of kitchen food safety to workers in industries dealing with food. The motivations driving the development of the game will be described as will the development process itself. An initial evaluation of the game, from both a technical and pedagogical point of view, will be presented as will conclusions on the viability of using a commercial game engine for the purpose of developing educational games.

The Use Of Task Based Mood-Induction Procedures To Generate High Quality Emotional Assets, Brian Vaughan, Charlie Cullen, Spyros Kousidis, Yi Wang, Ciaran Mcdonnell, Dermot Campbell

Conference papers

Detecting emotion in speech is important in advancing human-computer interaction, especially in the area of speech synthesis. This poster details experimental procedures based on Mood Induction Procedure 4, using performance related tasks to engender natural emotional responses in participants. These tasks are aided or hindered by the researcher to illicit the desired emotional response. These responses will then be recorded and their emotional content graded to form the basis of an emotional speech corpus. This corpus will then be used to develop a rule-set for basic emotional dimensions in speech.

A Critical Appraisal Of The Opportunities Currently Available For A More Energy Conscious Approach To Residential Building In Ireland, John Mcdonagh, Louis Gunnigan

Conference papers

This paper focuses on the particular advantages which off-site housing construction has over the more traditional methods of building especially where the efficient use and conservation of energy is concerned. It will explain why modern innovative methods of house construction not only have a clear advantage environmentally (big reductions in CO2 emissions) but also deliver substantial benefits to the end user or householder especially in the form of lower energy bills.

The ecological argument for off-site systems is a very powerful one but on its own is still unlikely to be the prime driver for widespread implementation. That growth is …

The Nonlinear Amplification Of Magnetic Fields By Cosmic Rays At Supernova Remnant Shocks, Brian Reville, Peter Duffy, Stephen O'Sullivan

Conference papers

A central problem in the theory of cosmic ray acceleration at supernova shock fronts is the generation of turbulent magnetic fields needed to scatter particles across a shock front. In this paper we build on previous studies [1], [2] into the effect of streaming cosmic rays produced by the outer shocks of supernova remnants on the stochastic component of the magnetic field. A three dimensional, MHD code has been constructed which demonstrates the nonlinear growth of the turbulent field.

Interface Design Requirements For Playing Pong With A Single Switch Device, Brian Mac Namee, John Gilligan

Conference papers

Motivated by a desire for increased accessibility in digital games, in this paper we consider the design requirements for an interface to a variation of the game Pong for single-switch users. We consider the issues in the design of accessible interfaces for games and propose a set of interface configurations for playing Pong, using this as a proof of concept for more elaborate games.

Bluetooth Assassin: A Location-Based Game For Mobile Devices, Miao Wang, Brian Mac Namee

Conference papers

This short paper will describe Bluetooth Assassin, a location-based game developed for mobile devices.

Feature Based And Feature Free Textual Cbr: A Comparison In Spam Filtering, Sarah Jane Delany, Derek Bridge

Conference papers

Spam filtering is a text classification task to which Case-Based Reasoning (CBR) has been successfully applied. We describe the ECUE system, which classifies emails using a feature-based form of textual CBR. Then, we describe an alternative way to compute the distances between cases in a feature-free fashion, using a distance measure based on text compression. This distance measure has the advantages of having no set-up costs and being resilient to concept drift. We report an empirical comparison, which shows the feature-free approach to be more accurate than the feature-based system. These results are fairly robust over different compression algorithms in …

Proximity In Context: An Empirically Grounded Computational Model Of Proximity For Processing Topological Spatial Expression., John D. Kelleher, Geert-Jan Kruijff, Fintan Costello

Conference papers

The paper presents a new model for context-dependent interpretation of linguistic expressions about spatial proximity between objects in a natural scene. The paper discusses novel psycholinguistic experimental data that tests and verifies the model. The model has been implemented, and enables a conversational robot to identify objects in a scene through topological spatial relations (e.g. ''X near Y''). The model can help motivate the choice between topological and projective prepositions.

Incremental Generation Of Spatial Referring Expressions In Situated Dialogue, John D. Kelleher, Geert-Jan Kruijff

Conference papers

This paper presents an approach to incrementally generating locative expressions. It addresses the issue of combinatorial explosion inherent in the construction of relational context models by: (a) contextually defining the set of objects in the context that may function as a landmark, and (b) sequencing the order in which spatial relations are considered using a cognitively motivated hierarchy of relations, and visual and discourse salience.

A Computational Model Of The Referential Semantics Of Projective Prepositions, John D. Kelleher, Josef Van Genabith

Conference papers

In this paper we present a framework for interpreting locative expressions containing the prepositions in front of and behind. These prepositions have different semantics in the viewer-centred and intrinsic frames of reference (Vandeloise, 1991). We define a model of their semantics in each frame of reference. The basis of these models is a novel parameterized continuum function that creates a 3-D spatial template. In the intrinsic frame of reference the origin used by the continuum function is assumed to be known a priori and object occlusion does not impact on the applicability rating of a point in the spatial template. …
