Abstract
When a user is looking for a product recommendation they usually lack expert knowledge regarding the items they are looking for. Ontologies on the other hand are crafted by experts and therefore provide a rich source of information for enhancing preferences. In this paper we significantly extend previous work on exploiting ontological information by allowing the user to specify preferences in a more expressive manner. Rather than allowing for only one preferred target concept, we allow a ‘chain’ of user preferences. Furthermore, we treat information from the underlying ontology of the domain as a secondary preference structure. We then show how to assemble these two preference structures (user and ontology) into a preference over items.
