— This paper proposes a personalized web-based system with evolving automatic indexing that may be used in multimedia courses. Instructors may use the system to create and deliver different presentations, and individual learners may use it to retrieve resources personalized according to their different learning needs. Unlike similar systems which have a repository of fixed resources, this system uses a web crawler that harvests the web for multimedia resources to continuously update the links in its database and to continuously check the validity of the stored links. This makes the system always up-to-date. The importance of the system lies in its new approach to represent web resources, and in using continuously updated resources to provide responses adapted to users needs while saving the users the need to interact directly with the web.
