Technical Report: A Framework For Confusion Mitigation In Task-Oriented Interactions, Na Li, Robert J. Ross

Articles

Confusion is a mental state that can be triggered in task-oriented interactions and which can if left unattended lead to boredom, frustration, or disengagement from the task at hand. Since previous work has demonstrated that confusion can be detected in embodied situated interactions from visual and auditory cues, in this technique report, we propose appropriate interaction structures which should be used to mitigate confusion. We motivate and describe this dialogue mechanism through an information state-style policy with examples, and also outline the approach we are taking to integrate such a meta-conversational goal alongside core task-oriented considerations in modern data driven …

A Method For Generating A Non-Manual Feature Model For Sign Language Processing, Robert G. Smith Dr, Markus Hofmann Dr

Articles

While recent approaches to sign language processing have shifted to the domain of Machine Learning (ML), the treatment of Non-Manual Features (NMFs) remains an open question. The principal challenge facing this method is the comparatively small sign language corpora available for training machine learning models. This study produces a statistical model which may be used in future ML, rules-based, and hybrid-learning approaches for sign language processing tasks. In doing so, this research explores the emerging patterns of non-manual articulation concerning grammatical classes in Irish Sign Language (ISL). The experimental method applied here is a novel implementation of an association rules …

Dialogue Policies For Confusion Mitigation In Situated Hri, Na Li, Robert J. Ross

Articles

Confusion is a mental state triggered by cognitive disequilibrium that can occur in many types of task-oriented interaction, including Human-Robot Interaction (HRI). People may become confused while interacting with robots due to communicative or even task-centred challenges. To build a smooth and engaging HRI, it is insufficient for an agent to simply detect confusion; instead, the system should aim to mitigate the situation. In light of this, in this paper, we present our approach to a linguistic design of dialogue policies to build a dialogue framework to alleviate interlocutor confusion. We also outline our sketch and discuss challenges with respect …

What Is A Metaphorical Collocation?, Jakob Patekar

Articles

In research on collocations published in English we encounter, albeit rarely, the use of the notion “metaphorical collocations”. It is interesting to note that seldom if ever are metaphorical collocations defined in any way in these studies, suggesting that researchers find the term self-explanatory. However, seeing that metaphorical collocations are an exciting area of research that is yet to draw attention from the wider community ofresearchers, the aim of this paper is to analyze the current understanding of what a metaphorical collocation is by examining the theoretical foundations as well as studies, specifically those published in English (as the language …

Automaticity Of Lexical Access In Deaf And Hearing Bilinguals: Cross-Linguistic Evidence From The Color Stroop Task Across Five Languages, Rain G. Bosworth, Sarah C. Tyler, Eli M. Binder, Jill P. Morford

Articles

The well-known Stroop interference effect has been instrumental in revealing the highly automated nature of lexical processing as well as providing new insights to the underlying lexical organization of first and second languages within proficient bilinguals. The present cross-linguistic study had two goals: 1) to examine Stroop interference for dynamic signs and printed words in deaf ASL-English bilinguals who report no reliance on speech or audiological aids; 2) to compare Stroop interference effects in several groups of bilinguals whose two languages range from very distinct to very similar in their shared orthographic patterns: ASL-English bilinguals (very distinct), Chinese-English bilinguals (low …

A Lexical Frequency Analysis Of Irish Sign Language, Robert G. Smith, Markus Hofmann

Articles

Word frequency has a significant impact on language acquisition and fluency. It is often a point of reference for the teaching and assessing of a language and indeed, as a control for psycholinguistic studies. This paper presents the results of the first objective frequency analysis of lexical tokens from the Signs of Ireland corpus. We investigate the frequency of fully lexical, partly lexical and non-lexical signs in Irish Sign Language as they are presented in the corpus. We confirm the accuracy of the lexical gloss frequency data with a supplementary corpus subset that is tagged for grammatical class and additional …

Size Matters: The Impact Of Training Size In Taxonomically-Enriched Word Embeddings, Alfredo Maldonado, Filip Klubicka, John D. Kelleher

Articles

Word embeddings trained on natural corpora (e.g., newspaper collections, Wikipedia or the Web) excel in capturing thematic similarity (“topical relatedness”) on word pairs such as ‘coffee’ and ‘cup’ or ’bus’ and ‘road’. However, they are less successful on pairs showing taxonomic similarity, like ‘cup’ and ‘mug’ (near synonyms) or ‘bus’ and ‘train’ (types of public transport). Moreover, purely taxonomy-based embeddings (e.g. those trained on a random-walk of WordNet’s structure) outperform natural-corpus embeddings in taxonomic similarity but underperform them in thematic similarity. Previous work suggests that performance gains in both types of similarity can be achieved by enriching natural-corpus embeddings with …

Exploring Diversity With A "Culture Box" In First-Year Legal Writing, Ann N. Sinsheimer

Articles

Studying law is in many ways like studying another culture. Students often feel as though they are learning a new language with unfamiliar vocabulary and different styles of communication. Throughout their legal education, students are also exposed to a profession comprised of unique traditions and expectations. As a result, learning law takes time and energy. It can be both engaging and frustrating and may even challenge some of students’ values and belief systems. To ease her students’ transition to law school, the author starts her course each year with a “culture box” exercise, which encourages students to examine who they …

Robot Perception Errors And Human Resolution Strategies In Situated Human-Robot Dialogue, Niels Schütte, Brian Mac Namee, John D. Kelleher

Articles

Errors in visual perception may cause problems in situated dialogues. We investigated this problem through an experiment in which human participants interacted through a natural language dialogue interface with a simulated robot.We introduced errors into the robot’s perception, and observed the resulting problems in the dialogues and their resolutions.We then introduced different methods for the user to request information about the robot’s understanding of the environment. We quantify the impact of perception errors on the dialogues, and investigate resolution attempts by users at a structural level and at the level of referring expressions.

Perception Based Misunderstandings In Human-Computer Dialogues, Niels Schütte, John D. Kelleher, Brian Mac Namee

Articles

In a situated dialogue, misunderstandings may arise if the participants perceive or interpret the environment in different ways. In human-computer dialogue this may be due the sensor errors. We present an experiment system and a series of experiments in which we investigate this problem.

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.

Applying Computational Models Of Spatial Prepositions To Visually Situated Dialog, John D. Kelleher, Fintan Costello

Articles

This article describes the application of computational models of spatial prepositions to visually situated dialog systems. In these dialogs, spatial prepositions are important because people often use them to refer to entities in the visual context of a dialog. We first describe a generic architecture for a visually situated dialog system and highlight the interactions between the spatial cognition module, which provides the interface to the models of prepositional semantics, and the other components in the architecture. Following this, we present two new computational models of topological and projective spatial prepositions. The main novelty within these models is the fact …

The Coke Side Of Life:An Exploration Of Pre-Schoolers' Constructions Of Product And Selves Through Talk-In-Interaction Around Coca-Cola, Olivia Freeman

Articles

Abstract Purpose – This paper proposes the activity-based focus group as a useful method with which to generate talk-in-interaction among pre-schoolers. Analytically, it aims to illustrate, how transcribed talk-in-interaction can be subjected to a discourse analytic lens, to produce insights into how pre-schoolers use ‘Coca-Cola’ as a conversational resource with which to build product-related meanings and social selves. Design/methodology/approach - Fourteen activity-based discussion groups with pre-schoolers aged between two and five years have been conducted in a number of settings including privately run Montessori schools and community based preschools in Dublin. The talk generated through these groups has been transcribed …

Troxel And The Rhetoric Of Associational Respect, David J. Herring

Articles

A recent decision by the United States Supreme Court has brought into sharp focus important questions about the nature and extent of parents' prerogatives to dictate how their children are raised. In the case of Troxel v. Granville, the Court addressed a Washington third-party visitation statute that permitted "any person" to petition for visitation with a child. Under the statute, a petitioner had to allege that visitation would serve the child's best interest. A judge hearing such a petition could order visitation whenever he or she found that such visitation may serve the child's best interest.

The United States …
