It still faces some problems such as hard to acquire user query intention,the lower semantic analysis ability and semantic expansion ability,the coverage area of single ontology is comparatively small,and with the poor concept semantics,the lower automatic level and visualization functions,etc.For solving these problems,this paper puts forward a kind of automatic semantic retrieval and visualization model based on ontology integration.Experiment show: the proposed model can not only improve the preci sion of the retrieved results,but also well satisfy users’demand of accurate retrieval and visual retrieval under the environment of the newly semantic Web.
