针对煤矿安全事件信息的特点，提出了基于煤矿安全事件的 Web 信息抽取方法，主要包括页面清洗、抽取规则生成、Web信息抽取。页面清洗作为预处理阶段，用于删除Web页面中的 HTML标识、脚本、css段等无用信息；抽取规则生成是根据信息特征，定位信息在页面的位置；通过实验验证基于煤矿安全事件的 Web信息抽取方法的可行性，结果表明本文提出的信息抽取方法针对中小型规模的信息抽取具有很高的准确性和有效性。

In this paper,by taking into account characteristics of safety issue information in coal mining,we propose a Web information retrieval strategy based on coal mining safety issues?Our method includes cleaning webpage,generating extraction rule,and retrieving Web informaG tion? Webpage cleaning,as a pretreatment,is used for useless information such as HTML laG bels,scripts,and css parts in webpages?Extraction rule generation is used for finding the exact positions of the information in the webpage,which is based on the characteristics of the informaG tion?Moreover,experimental results in this paper demonstrate the possibility of Web informaG tion retrieval based on coal mining safety issues,and the experimental results further show the accuracy and efficiency of our proposed information retrieval method,in particular for small and middle scale information retrieval tasks.
