摘　　要：为解决因Web信息量巨大且具有动态性、不规则性,Web信息查询和Web信息集成存在很大困难,研究了对HTML格式的Web文档的信息抽取,提出了一种基于DOM的Web信息抽取方法。该方法通过附加语义、样本学习生成基于DOM路径的抽取规则,利用遍历DOM树实现信息抽取。本方法可用于Web查询,也可用于信息集成系统中包装器的构造。Due to the information on the Web being tremendous, dynamic and irregular, it is difficult to query information on the Web or to integrate information from the Web. This paper mainly discusses an approach of information extraction from Web documents of HTML format and presents a DOM-based method of fast information extraction. This method generates information extraction rules that is based on DOM path through attaching syntax information and sample-learning. It implements information extraction through traveling DOM tree. The method can be applied to Web query and wrapper generation in information integration system.
