A User Modeling Approach to Web Based Adaptive Educational Hypermedia Systems

In this paper, a new user modeling approach has been developed to determine the knowledge status of user in Adaptive Educational Hypermedia System (AEHS). The approach is based on forming the domain model and determining relations among elements of that model to decide the knowledge status of user from domain model independently. The proposed method provides flexibility to individual learning or studying steps. In comparison to the literature, the proposed approach enables quick and powerful adaptation for matching instructional needs of users. The difficulties faced in developing such a system are purifying the gathered data, obtaining and evaluating useful data and providing a powerful adaptation effect in a short time.
