For the limitations of user interest model construction in the knowledge recommendation sys-tem,this paper proposes a method of user interest model construction based on domain ontology.At the ba-sis of ontology concept hierarchy tree,this algorithm collect the basic information through the web log atfirst,then using ontology editing tools to create domain ontology.To classify users based on the algorithmof the similarity and to establish a user model for each type of users.Finally,Update user model accordingto interesting.Experimental result shows that this model have higher reliability and accuracy to describeuser's interests.
