针对Web信息查询缺乏对查询概念的相关语义这一问题,引入一种本体的形式化模型,通过引入本体内聚度等概念建立本体中概念间的语义关联,从而便于对常识知识的处理,并作为语义扩展及缓存的依据,由此建立起查询的上下文关联及联想,给查询带来较好的适应性.
Aiming at the lack of related semantics of query concept in Web information query, this paper introduces a formal model of ontology. By introducing concepts such as ontology cohesion, semantic association among concepts in ontology can be facilitated, and the common knowledge can be processed easily. As a basis for semantic extension and caching, contextual associations and associations of queries are established to bring better adaptability to queries.
