> 中文摘要: 为了对WEB上不规则的、动态的信息按照数据库的方式集成和查询,采用对象交换模型(object exchange model,简称OEM)建立了WEB信息模型.为了将页面中各个部分表示为对应的OEM对象,设计了半结构化信息的抽取算法,并给出测试结果.该方法可以抽取结构化和半结构化的信息,比现有的抽取方法通用性更强.
Abstract:In order to integrate and query irregular and dynamic information on WEB in a database-like fashion, the authors use object exchange model (OEM) to construct information model of WEB in this paper. To express each component of pages as an OEM object, the authors design an algorithm which extracts semi-structured data from HTML pages, and the testing results are given. This method can extract structured and semi-structured data. It has better applicability than other existing methods.
