Research on Ontology-based User Interest Model Construction

Aiming at the difficulties and deficiency of ontology construction in user interest model and model updating,this paper presents an ontology-based approach to construct user interest model. The approach uses domain ontology,user personal ontology,correction ontology and ontology updating to achieve the model construction,it abandons the method of train,study and clusting to the construction of domain ontology ,reguires category from ODP,updates user interest timely through correcting ontology construction,washing out users' outdate interest and adjusting interest degree. Experimental results show that this model is easier to construct,and accuracy and timely of it is improved.
