【摘要】 提出了一种基于多领域本体的智能查询系统的形式化模型,并且对系统及其特点进行了详细分析。该模型引入本体层来对知识库系统中的语义和信息内容进行描述,充分体现了用户查询中的语义信息,既方便用户进行查询,又增加了查询结果的相关性。同时,系统能够及时反映知识库的动态变化,简化了单一的全局本体所导致的一致性及效率问题。更多还原

【Abstract】 A model of intelligent query answering system based on multi-domain ontology is presented. Then the running process and the properties of the system are discussed. Ontologies are introduced to describe the semantic information of knowledge bases in order to express fully the semantics of user’s query. This model improves the relevance of the answering results and users’ content. At the same time, the system can reflect the dynamic change of the information in the knowledge bases and reduce the consistency and effect problem caused by using globe ontology.更多还原
