摘　　要：不同的本体之间普遍存在着很多语义互操作的问题,如:语义冲突和结构异构,这些问题严重地影响了本体之间的知识共享和重用;同时也给本体查询服务带来了很大的困难,为此,提出一种基于WordNet的本体查询框架OQ-WordNet.该框架首先使用语义词典库WordNet来精确地计算不同本体(源本体)之间概念的相似度;然后通过本体集成和本体映射方法为所有源本体生成一个目标本体,并建立它们之间的语义映射关系;最后OQ-WordNet采用本体查询语言SPARQL来实现本体之间的查询功能.There are many problems of semantic interoperability between different ontologies, such as semantic confliction and structure heterogeneous. These problems seriously influenced knowledge sharing and reusing between ontologies, and made it difficult to the service of ontology query. In view of this, this paper proposes framework of ontology query based on WordNet, which is called OQ-WordNet. This framework firstly calcu- lates similarities for concepts from different ontologies （i. e. , source ontologies） precisely by the lexicon WordNet. Then, OQ-WordNet applies the methods of ontology mapping and integration to generate a new on- tology, called target ontology, and to create semantic mappings for these ontologies. Finally, OQ-WordNet a- chieves the function of ontology query by SPARQL that is a kind of ontology query language.
