Recently, many such classifiers are trained with Web pages which are labeled manually or extracted from the open directory project (ODP), and then the classifiers judge the topical relevance of WebPages pointed to by hyperlinks in the crawler frontier. Though one can obtain labeled WebPages with comparative...
