This Ontology adopts weighted XML model and uses weight in concepts and their relationship to express the difference of users' interest effectively,which can improve the ability of expressing users' interest and their relationship with centripetal weight spreading activation strategy in order to explore more valuable users' interest. Meantime, this paper also discusses how to use this Ontology to transform heterogeneous user personalized profile to consistent comparable model with the broken-and-reconstruction strategy, and how to match corresponding heterogeneous user personalized profile in detail. Finally, the result of correlative tests and experiments are concluded.
