摘要
Abstract
Web text extraction is the foundation of Web information processing work (information retrieval, text mining, etc.). Based on the statistical analysis of theme pages, including body features and structure characteristics, this paper puts forward a kind of theme pages text extraction method combining Web page text features and HTML tags characteristics. The text content block is acquired according to the DOM tree parsed from the Web pages, and then the characteristics of noise information are analysed in the text content block in order to remove the noise information. Experiments show this method has higher accuracy and recall rate.关键词
