【摘要】：为了便于机器理解和有效挖掘Web内容,为Web页面结构及查询接口进行了建模．采用基于元本体的分层体系结构,分离了本体与语境,分层了概念和实例,是一个逐层实例化的过程．与数据库模式一样,Web页面结构及查询接口也由一些基本组件构成,这些组件及其之间的关系能灵活设置．模型的层次分明,具有良好的共享性和扩展性．利用基于元本体的分层体系结构,不但能为页面结构和查询接口建模,而且利用这种本体与语境相分离的机制能为查询结果页面之间的语义关系建模,提高搜索引擎的检索精度．
[Abstract]:In order to facilitate machine understanding and effective mining of Web content, Web page structure and query interface are modeled. A hierarchical architecture based on meta-ontology is used to separate ontology and context, layering concepts and instances, which is a process of layer-by-layer instantiation. This component is composed of these components and their relationships can be flexibly set. The model has a clear hierarchy, good sharing and scalability. Using the hierarchical architecture based on meta-ontology, not only can the page structure and query interface be modeled, but also can the query results between pages by using the mechanism of ontology and context separation. The semantic relation modeling improves the retrieval accuracy of search engines.
