Abstract:

This thesis details the development of a novel and practical Conversational Agent for the Arabic language called ArabChat. A conversational Agent is a computer program that attempts to simulate conversations between machine and human. In this thesis, the term 'conversation' or 'utterance' refers to real-time chat exchange between machine and human. The proposed framework for developing the Arabic Conversational Agent (ArabChat) is based on Pattern Matching approach to handle users' conversations. The Pattern Matching approach is based on the matching process between a user's utterance and pre-

Abstract:

Chatbots, also called conversational agents, with speech interfaces are being used to a greater and greater extent, but there are still many areas that are not completely explored. The idea of this project was born out of the belief that there is a need for an assistant in the kitchen that is able to search for recipes, answer questions regarding them and guide and assist the user throughout the cooking process, all through conversation since the hands are busy. This paper begins with an introduction in the subject of conversational agents and the related technology, then similar, already exis

Abstract:

Poor diet and physical inactivity are two of the biggest healthcare challenges we are facing, and are related to individuals lifestyle. In fact, a poor lifestyle is strongly correlated to chronic diseases, the leading causes for morbidity and mortality. Adhering to a healthy diet and following an active lifestyle are thus necessary to promote the overall health. However, maintaining a healthy diet and physically active lifestyle is hard. This is due to poor health literacy, lack of awareness, motivation and effective intervention support. Recent years have seen a blast of mHealth apps for hea

Abstract:

"Consider two people having a face-to-face conversation. They sometimes listen, sometimes talk, and sometimes interrupt each other. They use facial expressions to signal that they are confused. They point at objects. They jump from topic to topic opportunistically. When another acquaintance walks by, they nod and say hello. All the while they have other concerns on their mind, such as not missing the meeting that starts in 10 minutes. Like many other humans behaviors, these are not easy to replicate in artificial agents. In this work we look into the design requirements of an embodied agent th

However, the possibility of cloning the gesture expressivity of a real person has received little attention so far. Gesture expressivity combines the style and mood of a person.

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.

Abstract:

Avec le nombre croissant d'utilisateurs novices des applications informatiques, le besoin d'une aide efficace est devenu critique. Afin de répondre à ce besoins, nous suggérons d'utiliser un Agent Conversationnel Assistant (ACA), c'est-à-dire une interface permettant l'utilisation de la langue naturelle (en effet celle-ci est utilisée spontanément dès qu'un problème surgit) ainsi qu'une présence rassurante pour les utilisateurs.Une étude préliminaire détaille la constitution (en combinant la collecte et l'utilisation de thesaurus) d'un corpus de requêtes dont nous justifions le besoin. Ce corp

Abstract:

Alzheimer's disease, the most common form of dementia, is estimated to occur in up to sixteen percent of people between the ages of 75 and 84. Deficits in linguistic skills that effect communication are a hallmark of the disease and have been the primary focus of past Alzheimer's research. Among other deficits, researchers have found that people with Alzheimer's often use indexical expressions without clear referents and convey less information that is relevant to the task they have been asked to perform than healthy subjects. Relatively little research has examined how Alzheimer's subjects us

Abstract:

Malgré la puissance de nos technologies de communication actuelles pour maintenir du contact social dans des situations extrêmes, elles restent insuffisantes pour totalement combler les sentiments de solitude et d'isolement. Le toucher social, est essentiel au bien-être humain, nous permet de développer et raffermir nos liens relationnels et est un puissant canal de communication des émotions. Le présent travail de thèse s'intéresse à la façon dont on peut munir des agents artificiels de capacités de toucher social. Qu'il s'agisse de robots ou de personnages virtuels, ces nouvelles entités soc

Abstract:

Embodied Conversational Agents (i.e., avatars; ECAs) are appearing in increasingly many everyday contexts, such as e-commerce, occupational training, and airport security. Also common to a typical person's daily life is persuasion. Whether being persuaded or persuading, the ability to change another person's attitude or behavior is a thoroughly researched topic. However, little is known about ECAs' ability to persuade and whether basic persuasion principles from human-human interactions will hold in human-ECA interactions. This work investigates this question. First, a broad review of persuasi

Abstract:

Lors d'une interaction, le comportement non-verbal apporte des informations sur l'état affectif de l'intervenant comme son attitude ou sa personnalité par exemple. Cela se traduit par des modulations dans l'utilisation de ses signaux sociaux : les variations dans les mouvements de tête, les expressions faciales ou la prosodie traduisent ces différents phénomènes affectifs. Désormais, l'utilisation d'agents conversationnels animés permet aux machines d'utiliser le même type de signaux sociaux. Ces agents peuvent ainsi améliorer la qualité de vie dans nos sociétés modernes s'ils proposent une in

Abstract:

Afin d’être considérés comme des partenaires crédibles lors d’une interaction, les agents virtuels doivent transmettre une attitude sociale adéquate. Cette attitude sociale exprimée par l’agent doit refléter la situation dans laquelle il se trouve. L’agent doit donc prendre en compte son rôle et sa relation sociale vis à vis de son interlocuteur lorsqu’il choisit comment réagir au cours de l’interaction. Afin de construire un tel agent capable de raisonner en fonction de son rôle et de sa relation, et capable d’adapter son attitude sociale, nous avons construit un modèle de prise de décision s
