Knowledge modelling for mediation system based on cooperative task: an e-learning application

Working on the elaboration of a development methodology for mediation systems integrated into cooperative information systems, we propose an architecture based on three components: the first one concerns cooperation, the second one, assistance and the last one concerns knowledge necessary for the two precedents. In this paper we present particularly the knowledge component. This knowledge has two natures: static knowledge on the domain, and the knowledge acquired during the cooperative use of the system, mainly the activity memory and the descriptions of problem-solving. To illustrate knowledge modelling, we are interested in the cooperative activities of follow-up, management and evaluation of student's projects, assisted by the iPedagogique tool
