【Abstract】 A Web page usually consists of many information blocks.In addition to main content blocks,it usually contains advertisement,navigation panels,and copyright etc.In view of the information of the Web pages,such as the size and the position of the Web block,and based on the features of the Web pages,a block-analysis-based and auto-adjusted threshold approach is proposed to eliminate the noise content in Web pages.This approach markedly reduces the noise contents in Web pages,and the experimental result of Web page classification verifies the validity of the approach presented in this paper.更多还原
