Abstract
With the rapid development of Internet,the network resources are getting more and more abundant,how to extract information from network,especially from Deep Web has been focused on.A new generation of Ajax-based web information extraction has become a hot topic.By analyzing the key technology of the Ajax-supported Deep Web Crawler,this paper puts forward the architecture of the Ajax-Supported Deep Web Crawler,and illustrates an algorithm to crawl the Ajax-supported Deep Web automatically,which lay the foundation for the design of the overall framework of an Ajax-supported Deep Web Crawler.
