Abstract

The system and method for identifying invalid address web pages of the invention extract feature attributes from invalid address web pages marked artificially, and take sparse hash mapping of featureattributes as input of clustering algorithm to obtain multi-cluster uniform resource locator. The longest text shared by multi-cluster URLs from the starting bit is obtained by calculating the matching degree. A blacklist of first and second attribute texts and invalid addresses is determined based on the longest text. Determining first and second texts according to the web page to be identified;When the first attribute text column of the blacklist contains the first text and the second text contains all the contents of the second attribute text corresponding to the first attribute text identical to the first text, the web page to be recognized is determined to be an invalid address web page. The method or the system in the invention obtains an invalid address blacklist through clusteringanalysis of invalid address webpages, and identifies the webpages to be classified through the blacklist, thereby improving the objectivity and the operation efficiency of the method or the system.
