Implementation of Web Information Pre-processing Scheme in Online Public Opinion Analysis

Li Shu-chen Liu Yun Li Yong (Key Laboratory of Communication & Information Systems,Beijing Jiaotong University,Beijing Municipal Commission of Education, Beijing 100044)  
In online public opinion analysis system,the information extraction technology based on the analysis of web pages structure,and the data storage technology are used to implemente the web information pre-processing scheme.According to the internal structure of web pages HTML,a template containing web page HTML DOM node path is designed for web pages information parsing.Via the analysis of URL features, the relation mechanism among web pages are built.Taking advantage of this mechanism in data storage, the efficiency has been improved.
