Abstract: Media tagging is significantly improved by fusing subjective, user-specific tags with collaborative, community based tags. Users share multimedia metadata tags in a network of users, to improve automatic tag generation for personal multimedia collections without compromising media privacy. In one method, a combined set of annotation tags is suggested to a user, for use in annotating a given media file. The combined set includes a first set drawn from a private, user-specific repository, and a second set drawn from a public, shared repository. In each case, determining which tags are suggested involves computing similarities between an attribute vector associated with the media file being tagged and attribute vectors associated with the tags. An attribute vector is a set of values representing given types of contextual metadata. The similarity determinations may be weighted according to user-specific and shared weights, and these weightings can be adapted to reflect user and community preferences.
