چکیده

Today the computer is changing from a big, grey, and noisy thing on our desk to a small, portable, and ever-networked item most of us are carrying around. This new found mobility imposes a shift in how we view computers and the way we work with them. When interaction can occur anywhere at any time it is imperative that the system adapts to the user in whatever situation the user is in. To facilitate this adaptivity we propose a two tier architecture. A middleware layer implementing a general mechanism for aggregating and maintaining contextual information. The second part offers automatic situation assessment through Case-Based Reasoning. We demonstrate a multi-agent system for supplying context-sensitive services in a mobile environment. RÉSUMÉ. De nos jours, l’ordinateur est en passe de changer de l’objet gros, gris et bruyant sur notre bureau à un objet petit, transportable et connecté que la plupart d’entre nous transporte. Cette nouvelle mobilité impose sur notre vision des ordinateurs et la manière dont nous travaillons avec eux. Lorsque nous pouvons interagir avec les autres n’importe où, n’importe quand, il est impératif que ce soit le système qui s’adapte à l’utilisateur et à la situation, et non l’inverse. Pour faciliter cette adaptativité, nous proposons une architecture deux-tiers avec une couche logiciel personnalisé implémentant un mécanisme général d’agrégation et de maintenance d’informations contextuelles. Dans un deuxième temps, nous proposons une évaluation automatique d’une situation à partir d’un raisonnement à base de cas. Nous montrons finalement comment un système multi-agent peut fournir des services sensibles au contexte dans un environnement mobile.
