Abstract:

Task-oriented dialogue systems are designed to interact and assist users to achieve a certain goal. A typical approach to model such systems is a component-based approach that involves multiple components, each performing a sub-task of the dialogue system. These components are generally modelled based on a given domain with domain-specific features making them expensive to port to new domains and requiring large in-domain data. In this thesis we investigate the role of domain information in data-driven task-oriented systems. We note that domain information is widely unused in current neural m

Abstract:

Task-oriented dialogue systems are a popular way for organisations to generate extra value both internally and for customers. Modern approaches for these dialogue systems that use neural networks to enable training directly on written dialogues are very data hungry, which complicates their implementation. Crowdsourcing is an attractive solution for generating this type of training data, but the method also comes with several difficulties. We introduce a new method for generating training data based on parallel crowdsourcing of dialogues, as well as crowdsourced quality review. We use this meth

Abstract:

Les systèmes de dialogue orientés tâche, plus communément appelés chatbots, ont pour but de réaliser des tâches et de fournir des informations à la demande d’un utilisateur dans le cadre d’une conversation et d’un domaine précis (e.g. réservation d’un billet de train). Ces systèmes ont été largement adoptés par de nombreuses entreprises. Cependant, ils souffrent en pratique de certaines limitations : (1) ils sont dépendants des données d’entraînement nécessaires afin d’obtenir un système performant, (2) ils manquent de flexibilité et sont peu performants dès que le cas de figure rencontré en p

Abstract:

The Principle of Parsimony states that by and large, agents try to complete tasks using as little effort as possible. This thesis demonstrates that the Principle of Parsimony operates in human task-oriented dialogue by showing the effects of Parsimony in a corpus of human dialogues about a map navigation task and by using the main points of the analysis in order to guide simulated conversations between two computer agents within the JAM system. It makes four major contributions: an analysis of 'communicative posture', or a range of choices in dialogue which can be characterised by decisions ab

This thesis explores the implications of Lindblom's theory of Hyper- and Hypo-articulation (Lindblom, 1983, 1990) for word intelligibility and the likely application of phonological reduction processes in spontaneous discourse, using data from the HCRC Map Task Corpus. Lindblom claims that variability in articulatory clarity is a reflection of speakers' assessments of their listeners' information requirements: speakers hyper-articulate when listeners require maximum acoustic input from with information from other sources.

Abstract:

Task-oriented dialogue (ToD) systems need to interpret the user's input to understand the user's needs (intent) and corresponding relevant information (slots). This process is performed by a Natural Language Understanding (NLU) component, which maps the text utterance into a semantic frame representation, involving two subtasks: intent classification (text classification) and slot filling (sequence tagging). Typically, new domains and languages are regularly added to the system to support more functionalities. Collecting domain-specific data and performing fine-grained annotation of large amou

This thesis presents a discussion of proposed structuring principles for dialogue, and tests them empirically using data from the HCRC Map Task Corpus. The concepts of Cooperation (as described by Grice, and as used more generally in Linguistics), Coordination, Collaboration, Parsimony, Risk and Effort are ex¬ amined, and empirically testable hypotheses are developed, with which we are able to evaluate the claims for these principles in the context of task-oriented dialogue. In order to test our hypotheses, we categorise the utterances in our database in terms of Risk and Effort. Unlike Discou

Abstract:

During rehabilitation from Stroke, patients require assessment of their upper-limb motor control. Outcome measures can often be subjective and objective data is required to supplement therapist/patient opinion on progress. This can be performed through goniometry; however, goniometry can be time-consuming, have inaccuracies of ±23º, and is therefore, often not used. Motion tracking technology is a possible answer to this problem, but can also be costly, time-consuming and not suitable for the clinical environment.

Abstract:

The thesis seeks to develop an account of collaborative activities within the framework of ecological realism—an approach to psychology developed by James J. Gibson in the course of work on visual perception. Two main questions are addressed; one ontological, and one methodological. The ontological question is: given that collaborative activities take place within an environment, what kinds of structure must this environment contain? The response emphasizes the importance of relations which exist between entities, and which connect a given perceiver-actor with the other objects and individuals

Abstract:

Traditional development of goal-oriented conversational agents typically require a lot of domain-specific handcrafting, which precludes scaling up to different domains; end-to-end systems would escape this limitation because they can be trained directly from dialogues. The very promising success recently obtained in end-to-end chatbots development could carry over to goal-oriented settings: applying deep learning models for building robust and scalable goal-oriented dialog systems directly from corpora of conversations is a challenging task and an open research area.

The problem motivating this research is that ineffective communication may hamper systems development efforts.

This research problem motivated an analysis of the communication process and lead to the development of a temporal framework that delineates variables associated with task-oriented, end user/systems analyst communication interactions. Several variables within this framework are depicted in two theoretical models. The first mo

Two of the main needs when developing an information system for an organization are that system analysts know and understand the application domain and that the system properly supports the business processes of the organization. Consequently, elicitation of system requirements from business process models has been acknowledged as a suitable activity to deal with that needs. In addition, system requirements must be linked to subsequent development stages. However, system analysts can face many challenges when performing these activities.
