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)
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)
This article discusses security requirements for open distributed learning environments. Security is a critical issue, especially for highly interactive applications based on heterogeneous distributed architectures. In e-learning applications, security mechanisms have as their main purpose to protect against illegal access to information, so that(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)
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)
This paper presents a mechanism of coalition formation where agents solve a problem of diagnosis. Our approach considers that a diagnosis may be seen as the result of an emergent process where findings (at a microscopic level) are interpreted by entities (at a macroscopic level). At the micro-level agents interact and form coalitions. At the macro-level(More)
