The invention discloses an automatic identifying method for a webpage collecting template of a vertical search engine in cloud computing. The method comprises the following steps: randomly acquiring a certain quantity of sample webpages for a to-be-collected website; analyzing the existing webpages and extracting a characteristic attribute; collecting an attribute value into a data table and taking as training sample data for clustering, thereby acquiring different webpage templates; identifying classes of the webpage templates, taking as training samples and training to obtain a webpage template classifier; using the webpage template classifier for performing template classification on all the collected webpages and extracting information according to the classified templates. According to the method, webpage sampling is performed on different websites, and different analyzing templates are identified for different webpage structures in the websites by utilizing a data mining clustering/sorting algorithm, so that an intelligently analyzing purpose is achieved.
