ABSTRACT:
Methods of inferring user preferences using ontologies use ontology structure based similarity and an inference mechanism in defining ontology filtering (OF). Items are recommended to users by identifying items that the users may prefer, but may not have been aware of. This is performed by computing personalized scores for concepts and selecting an instance having a highest score.
