Abstract

This article describes the guidelines followed in the design of a framework for managing learning object repositories that can be applied to different domains. The main features of the framework are the engagement of the virtual learning community in authoring and maintenance tasks, along with the use of recommender system technology in order to provide personalised searching and retrieval features. This article mainly focuses on the recommendation tasks, which help to identify suitable resources for the students in the virtual learning community. The recommendation approach follows a cascade hybrid strategy that refines the decisions of a case-based recommender by using a collaborative one. The former provides resources that fit the current student profile and promote her learning process. The later includes in the retrieval process the opinion about the usefulness of the resources provided by other members of the virtual learning community.
