Abstract

This paper proposes several strategies for the combination of ontology-based user profiles to generate a shared semantic profile for a group of users. The performance of the strategies is theoretically and empirically evaluated in an existing personalization framework from a knowledge-driven multimedia retrieval system. Early experiments are reported here, which show the benefits of using semantic user preferences representations and providing initial evidence as to which profiles combination strategies are most appropriate for collaborative content retrieval tasks.
