Abstract This paper constructs domain Ontology firstly, and constructs user interest Ontology by the representation between user interest and domain Ontology, then construct user interest mode. It studies user interest Ontology similarity measure, and identifies the vertical weight by user interest similarity, the horizontal weight by time novelty. At last, it uses the improved weighted association rule algorithm to mine the concepts in domain Ontology, and realizes the cooperative recommendation oriented to content.
