This paper presents the principles of a Home Automation system dedicated to power management that adapts power consumption to available power ressources according to user comfort and cost criteria. The system relies on a multi-agent paradigm. Each agent is embedded into a power resource or an equipment, which may be an environment (thermal-air,(More)
This paper describes the Mediating Agent, an animated pedagogical agent inserted in a computational system for distance learning, which has the goal of motivating the student to learn as well as promoting a positive mood in the student, which is more appropriate to learning. In order to accomplish its function, the agent should recognize the student’s(More)
The Baghera project intends to develop theoretical and methodological foundations to guide the computer modelling and conception of learning environments. This paper presents the Baghera platform, which is founded on the principle that the educational function of a system is an emerging property of the interactions organised between its components: agents(More)
In this paper, we merge speech act theory, emotion theory, and logic. We propose a modal logic that integrates the concepts of belief, goal, ideal and responsibility and that allows to describe what a given agent expresses in the context of a conversation with another agent. We use the logic in order to provide a systematic analysis of expressive speech(More)
User modelling has been a central issue in the development of user-adaptive systems, which behaviour is usually based on the user's preferences, goals, interests and knowledge. This is particularly the case when the user is a student and the system is a computer-based learning environment. The aim of this paper is to present a mechanism for diagnosing and(More)
In this paper, we describe the multi-agent infrastructure underlying I-Help, an internet-based learning and peer-help system that was deployed over the last two years with over 1000 students at the University of Saskatchewan. The system contains a variety of learning resources, most prominently, public discussion forums, on-line materials, and a chat-tool(More)
This paper contributes to the design of intelligent buildings. A MultiAgents Home Automation System (MAHAS) is proposed which controls appliances and energy sources in buildings. The objective of this paper is to show that by using intelligent agents related to appliances, it is possible to improve the energy consumption/production in buildings. The(More)
This paper presents the principles of a Home Automation System dedicated to power management that adapts power consumption to available power ressources according to user comfort and cost criteria. The system relies on a multi-agent paradigm. Each agent, supporting a type of service achieved by one or several devices, cooperates and coordinates its action(More)
We discuss here the need to define what we call an agent conversational language, a language for Embodied Conversational Agents (ECA) to have conversations with a human. We propose a set of Expressive Multimodal Conversation Acts (EMCA), which is based on the Expressive Speech Acts that we introduced in a previous work, enriched with the multimodal(More)
In this paper some results achieved in the domain of multi-agent methodology applied to educational systems are presented. We have developed a distance learning environment based on a two-level multi-agent architecture. Two-levels are distinguished since the application is composed by two multi-agent systems (MAS). The higher-level MAS is composed of(More)
