The Application Of Fuzzy Logic In Determining Linguistic Rules And Associative Membership Functions For The Control Of A Manufacturing Process, Marcus Foley, John Mcgrory

Dissertations

Fuzzy logic is a form of multi-valued logic derived from fuzzy set theory. Its methodology aims to provide a definitive solution from information that may be construed as ambiguous, imprecise or noisy. Classical set theory studies the properties of sets, while fuzzy set theory investigates the degree to which an element can be related to a set. The aim of this project is to develop a control strategy for a specific technical challenge relating to the food processing sector based on the deployment of fuzzy logic control concepts. Specifically, in this paper the author is concerned with the ability to …

Automatic Annotation Of Referring Expression In Situated Dialogues, Niels Schütte, John D. Kelleher, Brian Mac Namee

Articles

To apply machine learning techniques to the production and interpretation of natural language, we need large amounts of annotated language data. Manual annotation, however, is an expensive and time consuming process since it involves human annotators looking at the data and explicitly adding information that is implicitly contained in the data, based on their judgment. This work presents an approach to automatically annotating referring expressions in situated dialogues by exploiting the interpretation of language by the participants in the dia- logue. We associate instructions concerning objects in the environment with automatically detected events involving these objects and predict the referents …

Domain Independent Sentiment Classification With Many Lexicons, Bruno Ohana, Brendan Tierney, Sarah Jane Delany

Conference papers

Sentiment lexicons are language resources widely used in opinion mining and important tools in unsupervised sentiment classification. We present a comparative study of sentiment classification of reviews on six different domains using sentiment lexicons from different sources. Our results highlight the tendency of a lexicon’s performance to be imbalanced towards one class, and indicate lexicon accuracy varies with the target domain. We propose an approach that combines information from different lexicons to make classification decisions and achieve more robust results that consistently improve our baseline across all domains tested. These are further refined by a domain independent score adjustment that …

Obtaining Speech Assets For Judgement Analysis On Low-Pass Filtered Emotional Speech, John Snel, Charlie Cullen

Conference papers

Investigating the emotional content in speech from acoustic characteristics requires separating the semantic con- tent from the acoustic channel. For natural emotional speech, a widely used method to separate the two channels is the use of cue masking. Our objective is to investigate the use of cue masking in non-acted emotional speech by analyzing the extent to which filtering impacts the perception of emotional content of the modified speech material. However, obtaining a corpus of emotional speech can be quite difficult whereby verifying the emotional content is an issue thoroughly discussed. Currently, speech research is showing a tendency toward constructing …

User Profile Construction In The Twin Personality-Based Recommender System, Alexandra Roshchina, John Cardiff, Paolo Rosso

Conference Papers

The information overload experienced by peo- ple who use online services and read user- generated content (e.g. product reviews and ratings) to make their decisions has led to the development of the so-called recommender systems. We address the problem of the large increase in the user-generated reviews, which are added to each day and consequently make it difficult for the user to obtain a clear picture of the quality of the facility in which they are interested.

In this paper, we describe the TWIN (“Tell me What I Need”) personality-based recom- mender system, the aim of which is to select …

The Discursive Construction Of Irish Early Childhood Education And Care Policy: A Critical Discourse Analysis, Rachel Kiersey

Doctoral

Conceptual distinctions between care and early childhood education have influenced and reinforced the construction of knowledge about the early childhood education and care (ECEC) policy area. Discursive constructions in policy texts permeate wider society and become embodied in the broad social domain as “truths”, establishing the status quo about how social issues are perceived. Close scrutiny of the knowledge constructed about key concepts within Irish ECEC policy texts between 1998 and 2008 can shed some light on the ideological perspectives shaping the truths about ECEC in Irish society. This research used a critical discourse analysis (CDA) methodology to investigate policy …

An Investigation Of The Body As Location In The Context Of Kristeva's Reading Of The Maternal Orientation Of The Abject, Pauline Keena

Masters

The aim of my research project is the generation and enhanced understanding of what is unspeakable, unrepresented, and beyond the resolve of logical thought in my art practice. I wanted to find a way to display the emerging evidence of what is there in the physical material manifestation and beyond. So I set up a studio based research context to begin an enquiry by engaging philosophic ideas in a set of physical relations through materials and making in the studio. Using the theoretical work of Kristeva, Lacan and Schon enabled me to structure and language the enquiry. Mapping philosophic ideas …

Naturalistic Emotional Speech Corpora With Large Scale Emotional Dimension Ratings, Brian Vaughan

Doctoral

The investigation of the emotional dimensions of speech is dependent on large sets of reliable data. Existing work has been carried out on the creation of emotional speech corpora and the acoustic analysis of emotional speech and this research seeks to build
upon this work while suggesting new methods and areas of potential. A review of the literature determined that a two dimensional emotional model of activation and evaluation was the ideal method for representing the emotional states expressed in
speech. Two case studies were carried out to investigate methods of obtaining natural
underlying emotional speech in a high quality …

Research, Development And Application Of A Learning Resource For Enhancing Listening And Spoken Skills In Spanish, Elena Paz Vizcaya

Conference papers

Native speech is directed towards native listeners, not designed for comprehension and analysis by language learners. Speed of delivery - or economy of effort - produce a speech signal to which the native listener can assign the correct words — there are no discrete words in the speech signal itself. Experience of using timescaling with recorded English has highlighted the benefit of making slowED speech available to the language learner or researcher, as opposed to slow speech – i.e delivered slowly. The main contribution to knowledge of this project is to generate a unique research and analysis corpus (audio resource) …

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

Conference Papers

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 …

Visual Salience And Reference Resolution In Situated Dialogues: A Corpus-Based Evaluation., Niels Schütte, John D. Kelleher, Brian Mac Namee

Conference papers

Dialogues between humans and robots are necessarily situated and so, often, a shared visual context is present. Exophoric references are very frequent in situated dialogues, and are particularly important in the presence of a shared visual context - for example when a human is verbally guiding a tele-operated mobile robot. We present an approach to automatically resolving exophoric referring expressions in a situated dialogue based on the visual salience of possible referents. We evaluate the effectiveness of this approach and a range of different salience metrics using data from the SCARE corpus which we have augmented with visual information. The …

Situating Spatial Templates For Human-Robot Interaction, John D. Kelleher, Robert J. Ross, Brian Mac Namee, Colm Sloan

Conference papers

People often refer to objects by describing the object's spatial location relative to another object. Due to their ubiquity in situated discourse, the ability to use 'locative expressions' is fundamental to human-robot dialogue systems. A key component of this ability are computational models of spatial term semantics. These models bridge the grounding gap between spatial language and sensor data. Within the Artificial Intelligence and Robotics communities, spatial template based accounts, such as the Attention Vector Sum model (Regier and Carlson, 2001), have found considerable application in mediating situated human-machine communication (Gorniak, 2004; Brenner et a., 2007; Kelleher and Costello, 2009). …

Reporting The Rhetoric, Implementation Of The United Nations Convention On The Rights Of The Child As Represented In Ireland's Second Report To The Un Committee On The Rights Of The Child: A Critical Discourse Analysis, Rachel Kiersey, Noirin Hayes

Articles

Ireland’s second periodic report to the United Nations Committee on the Rights of the Child (CRC) presents the government’s case that it is succeeding in protecting and promoting the rights of all children in Ireland. This article presents a critical discourse analysis of the governments Report to the CRC. Using a refined critical discourse analysis (CDA) model, based on the framework proposed by Chouliaraki & Fairclough (1999); the linguistic structure of the Report is examined alongside consideration of the wider socio-political context in which it exists. The Report is itself a promotional genre . It lists legislative change, strategy plans …

Dialogic Fluency - Why It Matters, Dermot Campbell, Yi Wang, Marty Meinardi, Bunny Richardson, Ciaran Mcdonnell, Charles Pritchard

Conference papers

Speech as an LSP: Many dialogues presented to language learners could be better described as ‘interleaved mini-monologues’, their purpose being to provide examples of grammatical sentences in realistic settings. Real dialogues, on the other hand, are worked out ‘live’, with neither speaker knowing in detail where the conversation will lead. Speaker interaction is marked to a large extent by prosody and often even good communicators sound disfluent if their half of the dialogue is judged in isolation. Dialogic fluency: The objective of dialoguing L1 speakers, however, is to realise a social or personal goal, with language only part of effective …

Dialogue And Roles In A Strategy Workshop: Discovering Patterns Through Discourse Analysis, Martin Duffy

Masters

Strategy workshops are frequently used by Executive management teams to discuss and formulate strategy but are under-researched and under-reported in the academic literature. This study uses Discourse Analysis to discover participant roles and dialogic patterns in an Executive management team’s strategy workshop, together with their effect on the workshop’s operation and outcome. The study shows how the workshop participants adopt different roles through their language and content. It then identifies a dialogic pattern in the workshop discourse, with the emphasis on achieving shared understanding rather than winning the debate. The workshop facilitator’s role is shown to bring discussion as a …

New Trends In Automatic Assessment: Ontology Matching, Maria Mitina, Patricia Magee, John Cardiff

Conference Papers

Instant individual feedback represents a result of assessment which allows for considerable improvements in both teaching and learning. In this paper we present the application of ontology matching techniques in automatic correction of students’ answers for SQL tests, which will provide teachers with instant feedback to facilitate manual correction and marking and which they can pass to the students. Students experience many problems learning SQL due to the necessity to memorise database schemas, unclear feedback from the database engine on the execution of the query, etc. The program environment utilising the described approach is designed to solve the abovementioned problems …

Html5 And The Learner Of Spoken Languages, Eoin Kilfeather, Dermot Campbell, Yi Wang, Ciaran Mcdonnell, Marty Meinardi, Bunny Richardson

Conference papers

Traditional corpora are not renowned for being user friendly. If learners are to derive maximum benefit from speech corpora, then better interfaces are needed. This paper proposes such a role for HTML5. DIT’s dynamic speech corpus, FLUENT, contains a limited series of informal dialogues between friends and acquaintances. They are characterised by naturalness and their audio quality and marked-up using a schema which allows learners to retrieve features of spoken language, such as speaker intention, formulaicity and prosodic characteristics such as speed of delivery. The requirement to combine audio assets and synchronous text animation has in the past necessitated the …

Topology In Composite Spatial Terms, John D. Kelleher, Robert J. Ross

Conference papers

People often refer to objects by describing the object's spatial location relative to another object, e.g. the book on the right of the table. This type of referring expression is called a spatial locative expression. Spatial locatives have three major components: (1) the target object that is being located (the book), (2) the landmark object relative to which the target is being located (the table), and (3) the description of the spatial relationship that exists between the target and the landmark (on the right of ). In English spatial relationships are often described using spatial prepositions. The set of English …

Intelligibility Of Electrolarynx Speech Using A Novel Actuator, Brian Madden, Mark Nolan, Ted Burke, James Condron, Eugene Coyle

Conference Papers

During voiced speech, the larynx provides quasi-periodic acoustic excitation of the vocal tract. Following a laryngectomy, some people speak using an electrolarynx which replaces the excitatory function of the absent larynx. Drawbacks of conventional electrolarynx designs include the buzzing monotonic sound emitted, the need for a free hand to operate the device, and difficulty experienced by many laryngectomees in adapting to its use. Despite these shortcomings, it remains the preferred method of speech rehabilitation for a substantial minority of laryngectomees. In most electrolarynxes, mechanical vibrations are produced by a linear electromechanical actuator, the armature of which percusses against a metal …

I Do Like Them But I Don’T Watch Them: Preschoolers’ Use Of Age As An Accounting Device In Consumption Evaluations, Olivia Freeman

Conference papers

This paper derives from a broader study of children’s consumer culture, specifically an investigation into how preschoolers employ commercial discourses as the building blocks of social selves and relations. Age-based repertoires are found to colour the various discourses produced. ‘Age’ is conceptualised as something that is made sense of for and by children through their utilisation of toys, media, consumables and other commercial artefacts. The ‘choosing child’ is addressed in empirical terms to reveal the social significance of ‘doing’ consumption related evaluations in the focus group setting. A CA-informed discourse analytic approach is utilised to focus on one aspect of …

The primary concern was to gather rich and deep data which would allow a credible account of …

Lost In Translation? How The Culture(S) Of The Technological University Dublin (Dit) Could Be Analysed Via A Lens Of Critical Discourse Analysis (Cda) Of Its Strategic Plan, And Other Documents, During Its Transition To Grangegorman, Ann Conway

Other resources

This paper discusses some of the theoretical foundations to critical discourse analysis (CDA) and will review the principles of CDA. It will attempt to answer how CDA can be understood and what conceptual tools it offers as a lens to view DIT’s changing culture and role in education and society during its transition to Grangegorman. This move from multiple sites to a ‘one size fits all’ campus is believed to be about better servicing the needs of society by ‘supporting the economic, social and cultural life of its people in one main campus’ (DEGW, 2009). CDA focuses on the links …

Personal Sense And Idiolect: Combining Authorship Attribution And Opinion Analysis, Polina Panicheva, John Cardiff, Paolo Rosso

Conference Papers

Subjectivity analysis and authorship attribution are very popular areas of research. However, work in these two areas has been done separately. We believe that by combining information about subjectivity in texts and authorship, the performance of both tasks can be improved. In the paper a personalized approach to opinion mining is presented, in which the notions of personal sense and idiolect are introduced and used for polarity classification task. The results of applying the personalized approach to opinion mining are presented, confirming that the approach increases the performance of the opinion mining task. Automatic authorship attribution is further applied to …

Perception And Acquisition Of Natural Authentic English Speech For Chinese Learners Using Dit's Speech Technologies, Yi Wang

Doctoral

Given that Chinese language learners are greatly influenced by their mother-tongue, which is a tone language rather than an intonation language, learning and coping with authentic English speech seems more difficult than for learners of other languages. The focus of the current research is, on the basis of analysis of the nature of spoken English and spoken Chinese, to help Chinese learners derive benefit from ICT technologies developed by the Technological University Dublin (DIT). The thesis concentrates on investigating the application of speech technologies in bridging the gap between students’ internalised, idealised formulations and natural, authentic English speech. Part of …

Measuring Variations Of Mimicry By Means Of Prosodic Cues In Task-Based Scenarios And Conversational Speech, Brian Vaughan, Celine De Looze

Other resources

Here, we address the measurement of mimicry, that is when speakers’ speech variations look like parallel patterns.

As a definition of mimicry, we often read in the literature description such as mimicry is “The situation where the observed behaviours of two inter-actants although dissimilar at the start of the interaction are moving towards behavioral matching”. These types of descriptions imply that mimicry is a linear phenomenon and that speakers tend to imitate over time. However, it can be assumed, especially when studying spontaneous speech, that there are rather phases of mimicry and non-mimicry and that mimicry should be rather …
