Abstract :
Information extraction from Web sites is nowadays a relevant problem, usually performed by software modules called wrappers. Introduced the relevant information extraction technology. A combination of HTML pages to extract information of the theme and extract the contents. First of all, to remove noise combination of visual block, the vision-based DOM tree denoising methods to improve the efficiency of extraction.
