A Ontology Methodology and Its Application to Web Page Modeling
-
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 make machine understand and mine web content effectively, it is necessary to model web page structure and querying interface included. Using a layered architecture based on meta-ontology, the modeling method separates contexts from ontology, and instances from concept. It is a process of instantiating hierarchically. Like database schema, web page structure and querying interface included have some basic components. These components and the relations among them can be established flexibly. The resulting models are well defined, have clear layers, and can be shared and extended. Using the architecture based on meta-ontology, modeling web page structure and interface is feasible; its separation mechanism is also useful to class resulting pages of search engine, and hence improves search precision.
