Seeing Is Believing: Body Motion Dominates In Multisensory Conversations, Cathy Ennis, Rachel Mcdonnell, Carol O'Sullivan

Articles

In many scenes with human characters, interacting groups are an important factor for maintaining a sense of realism. However, little is known about what makes these characters appear realistic. In this paper, we investigate human sensitivity to audio mismatches (i.e., when individuals’ voices are not matched to their gestures) and visual desynchronization (i.e., when the body motions of the individuals in a group are mis-aligned in time) in virtual human conversers. Using motion capture data from a range of both polite conversations and arguments, we conduct a series of perceptual experiments and determine some factors that contribute to the plausibility …

The Discursive Construction Of ‘Children’ And ‘Rights’ In Irish Early Childhood Policy, Rachel Kiersey, Nóirín Hayes

Conference Papers

This paper explores the construction of knowledge about ‗children‘, ‗rights‘ and ‗ECEC‘ in Irish early childhood policy discourses. This research forms part of a wider thematic research project exploring Irish early childhood policy design from a number of angles; this strand of the research is concerned with ―revealing meaning‖ from Irish ECEC policy texts through a critical discourse analysis study. The theoretical goal of a critical discourse analysis study aims to understand how specific realities have come into being in the policy area; how they are reproduced through policy literature, how language use is an integral facet of social processes, …

Do You See What I Mean? Computer-Mediated Discourse Analysis., Noel Fitzpatrick, Roisin Donnelly

Books/Book Chapters

This chapter explores a sociolinguistic approach to computer-mediated communication (CMC), by examining how higher education teachers use digital media to manage interpersonal interaction in their online courses, form impressions, shape and maintain relationships with their students. Previous studies have often focused on the differences between online and offline interactions, though contemporary research is moving towards the view that CMC should be studied as an embedded linguistic form in everyday life. The study of language in these contexts is typically based on text-based forms of CMC, (often referred to as computer-mediated discourse analysis). Within this, focus in the chapter is on …

Holodomor, Famine In Ukraine 1932-1933: A Crime Against Humanity Or Genocide?, Renate Stark

Irish Journal of Applied Social Studies

Famines in the main are man-made and not merely caused by the occurrences of food shortages, due to natural disasters. This article discusses the theories of famine in relation to food entitlement and adverse government policy. In the first part the focus is on the introduction of theories of famine, where it is examined in what way the entitlement and distribution of food, rather than food shortage, is often the underlying cause for famines. Famines are strongly enmeshed in either direct or indirect political decisions. Consequently, political systems have often intentionally created famine conditions and used starvation as a mechanism …

The Mozambique Eyecare Project: Implementing A Model That Addresses Uncorrected Refractive Error In Lusophone Africa., Stephen Thompson, Diane Wallace

Conference Papers

BACKGROUND

Optometric education and resources are drastically deficient in most of Africa, more so in Lusophone Africa where the problem is compounded by language barriers which isolate these countries from related developments in Africa and/or the developed world.

The Mozambique Eyecare Programme is a multi-partner collaboration between The International Centre for Eyecare Education (ICEE), Universidade Lúrio in Mozambique, Technological University Dublin, and the University of Ulster in Ireland, designed to address the need for optometric education in Lusophone Africa.

AIM

This paper aims to document the current situation with regards to human resource development in eyecare in Mozambique and offer …

Clustering Weblogs On The Basis Of A Topic Detection Method, Fernando Perez-Tellez, David Pinto, John Cardiff, Paolo Rosso

Conference Papers

In recent years we have seen a vast increase in the volume of information published on weblog sites and also the creation of new web technologies where people discuss actual events. The need for automatic tools to organize this massive amount of information is clear, but the particular characteristics of weblogs such as shortness and overlapping vocabulary make this task difficult. In this work, we present a novel methodology to cluster weblog posts according to the topics discussed therein. This methodology is based on a generative probabilistic model in conjunction with a Self-Term Expansion methodology. We present our results which …

A Study Of Accomodation Of Prosodic And Temporal Features In Spoken Dialogues In View Of Speech Technology Applications, Spyridon Kousidis

Doctoral

Inter-speaker accommodation is a well-known property of human speech and human interaction in general. Broadly it refers to the behavioural patterns of two (or more) interactants and the effect of the (verbal and non-verbal) behaviour of each to that of the other(s). Implementation of this
behavior in spoken dialogue systems is desirable as an improvement on the naturalness of humanmachine interaction. However, traditional qualitative descriptions of accommodation phenomena do not provide sufficient information for such an implementation. Therefore, a quantitative
description of inter-speaker accommodation is required. This thesis proposes a methodology of monitoring accommodation during a human or humancomputer dialogue, …

Radio Broadcasting In Europe: The Search For A Common Digital Future, Brian O'Neill, Helen Shaw

Books/Book chapters

Europe’s radio is also characterised by a long history of being defined and driven by the state, in highly centralized fashion in the case of countries such as France (Meadel 1994), or indeed in former totalitarian regimes of Eastern Europe (Paulu 1974), and along more federal or devolved lines in countries such as Germany, Switzerland and the Netherlands (Kuhn 1985). The development of state broadcasting monopolies in most European countries, established in the early years of the twentieth century following the invention of sound broadcasting, has ensured that there is an enduring shared common ideological approach to radio broadcasting, which …

Social Networking Sites: Evaluating And Investigating Their Use In Academic Research, Fiona Redmond

Dissertations

Researchers must collect and analyse new data that will enhance the body of knowledge. It is for this reason that data is of major importance to researchers. All aspects of a research project involve data, from navigating existing data, to understanding how data is used in the world and why it is important to learn to collect data and make predictions. Researchers need to consider the types of data that are possible and examine and weight each option so they can determine what sources of data will answer the research questions or hypotheses.

Researchers, who require a large amount of …

Pattern Recognition In Cytopathology For Papanicolaou Screening, Jonathan Blackledge, Dmitriy Dubovitskiy

Conference papers

A unique space oriented filer is presented in order to detect and isolate the cell of a nucleus for applications in cytopathology. A classification method for nuclei is then considered based on the application of a set of features which includes certain fractal parameters. Segmentation algorithms are considered in which a self-adjustable sharpening filter is designed to enhance object location. Although the methods discussed and the algorithms developed have a range of applications, in this work we focus the engineering of a system for automating a Papanicolaou screening test using standard optical images

Egal: Exploration Guided Active Learning For Tcbr, Rong Hu, Sarah Jane Delany, Brian Mac Namee

Conference papers

The task of building labelled case bases can be approached using active learning (AL), a process which facilitates the labelling of large collections of examples with minimal manual labelling effort. The main challenge in designing AL systems is the development of a selection strategy to choose the most informative examples to manually label. Typical selection strategies use exploitation techniques which attempt to refine uncertain areas of the decision space based on the output of a classifier. Other approaches tend to balance exploitation with exploration, selecting examples from dense and interesting regions of the domain space. In this paper we present …

An Empirically-Based Model For Perspective Selection In Route-Finding Dialogues, Robert J. Ross, Kavita E. Thomas

Conference papers

In this work we aim to computationally model the extent to which certain empirical factors affect spatial perspective selection as used in route-finding dialogues. In such dialogues, both interlocutors need to adopt a spatial perspective in which to describe movement direction. In map-based tasks such as the one we are concerned with, two perspective choices are typically available, i.e., route perspective, where projective terms are defined with respect to the perspective of the route follower themselves, e.g., ``go to your right'', or survey perspective, where projective terms are defined with respect to a global or allocentric perspective, e.g., ``go down'', …

Evaluating Sensorineural Hearing Loss With An Auditory Nerve Model Using A Mean Structural Similarity Measure, Andrew Hines, Naomi Harte

Conference papers

Hearing loss research has traditionally been based on perceptual criteria, speech intelligibility and threshold levels. The development of computational models of the auditory-periphery has allowed experimentation via simulation to provide quantitative, repeatable results at a more granular level than would be practical with clinical research on human subjects. This work seeks to create an objective measure to automate this inspection process and ranks hearing losses based on auditory-nerve discharge patterns. A systematic way of assessing phonemic degradation using the outputs of an auditory nerve model for a range of sensorineural hearing losses would aid in rapid prototyping development of speech-processing …

Space, Time And The Constitution Of Subjectivity: Comparing Elias And Foucault, Paddy Dolan

Articles

The work of Foucault and Elias has been compared before in the social sciences and humanities, but here I argue that the main distinction between their approaches to the construction of subjectivity is the relative importance of space and time in their accounts. This is not just a matter of the “history of ideas,” as providing for the temporal dimension more fully in theories of subjectivity and the habitus allows for a greater understanding of how ways of being, acting and feeling in different spaces are related but largely unintended. Here I argue that discursive practices, governmental operations and technologies …

Using Crowdsourcing For Labelling Emotional Speech Assets, Alexey Tarasov, Sarah Jane Delany, Charlie Cullen

Conference papers

The success of supervised learning approaches for the classification of emotion in speech depends highly on the quality of the training data. The manual annotation of emotion speech assets is the primary way of gathering training data for emotional speech recognition. This position paper proposes the use of crowdsourcing for the rating of emotion speech assets. Recent developments in learning from crowdsourcing offer opportunities to determine accurate ratings for assets which have been annotated by large numbers of non-expert individuals. The challenges involved include identifying good annotators, determining consensus ratings and learning the bias of annotators.

Current Policy Developments In European Media Literacy, Brian O'Neill

Articles

In August of 2009, the European Commission issued a formal recommendation on media literacy adding to a series of initiatives underway since 2006 to build a comprehensive European media literacy policy (Commission of the European Communities 2009). Media literacy is now a well-established concept referring to the ability to critically understand and use media in a variety of contexts (see Aufderheide 1997). Recognising that the way people use media is changing and that the volume of information received is enormous, the Commission notes that all citizens need to have the ability to access, analyse and evaluate images, sounds and texts …

Simulation Optimisation Methods In Supply Chain Applications: A Review, Amr Arisha, Waleed Abo-Hamad

Articles

The competitiveness and dynamic nature of today’s marketplace is due to rapid advances in information technology, short product life cycles and the continuing trend in global outsourcing. Managing the resulting supply chain networks effectively is challenged by high levels of uncertainty in supply and demand, confl ict objectives, vagueness of information, numerous decision variables and constraints. With such levels of complexity, supply chain optimisation has the potential to make a signifi cant contribution in resolving these challenges. In this paper, a literature review – based on more than 100 peer-reviewed articles – of state-of-the-art simulation-based optimisation techniques in the context …

Vocate: Auditory Interfaces For The Lok8 Project, John Mcgee, Charlie Cullen

9th. IT & T Conference

The auditory modality has a number of unique advantages over other modalities, such as a fast neural processing rate and focus-independence. As part of the LOK8 project’s aim to develop location-based services, the Vocate module will be seeking to exploit these advantages to augment the overall usability of the LOK8 interface and also to deliver scalable content in scenarios where the user may be in transit or requires focus-independence. This paper discusses these advantages and outlines three possible approaches that the Vocate module may take within the LOK8 project: speech interfaces, auditory user interfaces, and sonification.

Sentiment Classification Of Reviews Using Sentiwordnet, Bruno Ohana, Brendan Tierney

9th. IT & T Conference

Sentiment classification concerns the use of automatic methods for predicting the orientation of subjective content on text documents, with applications on a number of areas including recommender and advertising systems, customer intelligence and information retrieval. SentiWordNet is an opinion lexicon derived from the WordNet database where each term is associated with numerical scores indicating positive and negative sentiment information. This research presents the results of applying the SentiWordNet lexical resource to the problem of automatic sentiment classification of film reviews. Our approach comprises counting positive and negative term scores to determine sentiment orientation, and an improvement is presented by building …

Dit’S Dynamic Speech Corpus, Dermot Campbell, Ciaran Mcdonnell, Marty Meinardi, Charles Pritchard, Bunny Richardson, Yi Wang

Articles

The Technological University Dublin’s FLUENT Dynamic Speech Corpus is aimed at learners, teachers, authors and researchers. When the prototype is complete (target: July 2009) it will afford access to a unique audio resource based on dialogues. Users will be able to find samples of native-to-native speech on a chosen topic, listen to phonetically interesting sections and explore the dynamic environment which gave rise to the spoken features studied. At all stages the user will be able to slow down sequences for heightened intelligibility.

Approaches To Qualitative Research: Theory And Its Practical Application (A Guide For Dissertation Students), John Hogan, Paddy Dolan, Paul Donnelly

Books/Book Chapters

Qualitative research is a multifaceted approach that investigates culture, society and behaviour through an analysis and synthesis of people’s words and actions. Qualitative methods produce compelling knowledge of how and why people behave as they do, whether in organisational, family, personal, or other social roles.

The primary objective of this book is to introduce students to the concepts underlying qualitative research and how this kind of research can be conducted in a practical manner. To this end, it discusses various approaches to qualitative research and provides examples of these approaches being carried out in practice. In doing so, the book …

Dit’S Dynamic Speech Corpus And Dialogic Fluency, Dermot Campbell, Marty Meinardi, Bunny Richardson, Yi Wang, Ciaran Mcdonnell

Conference papers

Monologic fluency is characterised by a lack of pauses and a smooth oral delivery. Dialogic fluency in L1-L1 unscripted speech, however, is characterized by seeming dis-fluency, hesitations, false starts etc. Yet the L1 speakers make perfect sense to each other. The Dynamic Speech Corpus (DSC) currently being developed under the FLUENT project at the Technological University Dublin (DIT). In dialogue, language represents only one of the communication channels at play in what is a dynamic, unscripted social interchange rather than a stand-alone linguistic performance. The language stream is supplemented by pragmatic considerations and a greater emphasis on prosody. DIT’s DSC …
