Learning Traditional Irish Music Using A Pda, Bryan Duggan Jan 2006

Learning Traditional Irish Music Using A Pda, Bryan Duggan

Conference papers

A common problem experienced by musicians in traditional music sessions is that of recalling tunes on demand from a large repertoire. Traditional music is largely an oral medium and musicians may recall a name or player of a tune or set, but require hearing the first few notes to start the tune. In this paper, we present our work developing TunePal, a tool that can be used by musicians for the storage and retrieval of traditional music melodies for learning purposes. TunePal is specifically desiged to be used by musicians playing Irish traditional music in sessions as it supports the …

The R-Cube: Reviewing, Reinforcing And Rewarding After Successful Module Completion, Ciaran O'Leary Jan 2006

The R-Cube: Reviewing, Reinforcing And Rewarding After Successful Module Completion, Ciaran O'Leary

Conference papers

Revisiting material previously presented and successfully assessed can lead to much frustration among teaching staff and students. Despite this, it is often a requirement due to the time lag between the point at which a student begins a module and the time when they successfully passed a prerequisite module. Also, students who successfully pass a module fit into a number of categories, from those who were successful in all components of the assessment to those who displayed the minimum level of competence required for satisfaction of the learning outcomes. We introduce a novel instructional model which we predict will be …


Steering By Engagement:Towards An Integrated Planning And Evaluation Framework In Higher Education Institutes, Deirdre Lillis Jan 2006

Steering By Engagement:Towards An Integrated Planning And Evaluation Framework In Higher Education Institutes, Deirdre Lillis

Conference papers

Higher Education Institutes (HEIs) worldwide are investing significant resources in strategic planning and self study programs to improve institutional performance. Both are expensive undertakings in terms of the time invested by participants and it is not unusual to see both programs underway in a HEI at the same time. The underlying knowledge produced about the challenges facing the Institution and the necessary responses can be broadly similar although their methodologies and presentation may differ. This paper reports on the comparative effectiveness of three strategic planning and three self study programs undertaken in one HEI over an 8 year timeframe under …


Bar Raising Or Navel-Gazing?:The Effectiveness Of Self-Study Programmes In Eading To Improvements In Institutional Performance, Deirdre Lillis Jan 2006

Bar Raising Or Navel-Gazing?:The Effectiveness Of Self-Study Programmes In Eading To Improvements In Institutional Performance, Deirdre Lillis

Conference papers

Higher Education Institutes worldwide are investing significant resources in self study programmes to improve institutional performance, to enhance quality and to meet external stakeholder demands. The institutional impacts of both internally and externally mandated self study programmes is an area where little empirical research exists. A key question is whether self study programmes are effective (or otherwise) in leading to improvements in institutional performance and the reasons why. Covering an eight year period, from 1997–2006, this paper reports on the use of systematic evaluation methodology (Rossi et al., 2003) to evaluate the effectiveness of three self study programmes in leading …


Feature Based And Feature Free Textual Cbr: A Comparison In Spam Filtering, Sarah Jane Delany, Derek Bridge Jan 2006

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 Jan 2006

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 Jan 2006

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.


Structural Descriptions In Human-Assisted Robot Visual Learning, Geert-Jan Kruijff, John D. Kelleher, Gregor Berginc, Ales Leonardis Jan 2006

Structural Descriptions In Human-Assisted Robot Visual Learning, Geert-Jan Kruijff, John D. Kelleher, Gregor Berginc, Ales Leonardis

Conference papers

The paper presents an approach to using structural descriptions, obtained through a human-robot tutoring dialogue, as labels for the visual ob ject models a robot learns. The paper shows how structural descriptions can relate models for different aspects of one and the same object, and how relating descriptions for visual models and discourse referents enables incremental updating of model descriptions through dialogue (either robot- or human-initiated). The approach has been implemented in an integrated architecture for human-assisted robot visual learning.


A Computational Model Of The Referential Semantics Of Projective Prepositions, John D. Kelleher, Josef Van Genabith Jan 2006

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. …


Information Fusion For Visual Reference Resolution In Dynamic Situated Dialogue., Geert-Jan Kruijff, John D. Kelleher, Nick Hawes Jan 2006

Information Fusion For Visual Reference Resolution In Dynamic Situated Dialogue., Geert-Jan Kruijff, John D. Kelleher, Nick Hawes

Conference papers

Human-Robot Interaction (HRI) invariably involves dialogue about objects in the environment in which the agents are situated. The paper focuses on the issue of resolving discourse references to such visual objects. The paper addresses the problem using strategies for intra-modal fusion (identifying that different occurrences concern the same object), and inter-modal fusion, (relating object references across different modalities). Core to these strategies are sensori-motoric coordination, and ontology-based mediation between content in different modalities. The approach has been fully implemented, and is illustrated with several working examples


Spatial Prepositions In Context: The Semantics Of Near In The Presence Of Distractor Objects., Fintan Costello, John D. Kelleher Jan 2006

Spatial Prepositions In Context: The Semantics Of Near In The Presence Of Distractor Objects., Fintan Costello, John D. Kelleher

Conference papers

The paper examines how people’s judgements of proximity between two objects are influenced by the presence of a third object. In an experiment participants were presented with images containing three shapes in different relative positions, and asked to rate the acceptability of a locative expression such as ‘the circle is near the triangle’ as descriptions of those images. The results showed an interaction between the relative positions of objects and the linguistic roles that those objects play in the locative expression: proximity was a decreasing function of the distance between the object in the head position in the expression and …
