Abstract

The embodiment of the invention provides a webpage collection recommendation method and device. The method comprises the following steps: acquiring a plurality of seed webpages relevant to a keyword; determining semantic concepts of the seed webpages; clustering the semantic concept of each seed webpage, and obtaining a semantic structure; acquiring a plurality of webpages linked to each seed webpage as a plurality of extended webpages; determining a similarity between each extended webpage and the semantic structure; according to an extended webpage whose similarity is not lower than a first similarity threshold, updating the seed webpages; evoluting the semantic structure according to the updated seed webpages periodically and updating the extended webpages, and updating the seed webpages according to the evoluted semantic structure until reaching a preset webpage acquisition termination condition; and sorting and recommending various seed webpages which are updated in the last cycle. By using the embodiment of the invention, the webpages can be collected and recommended for users more accurately and comprehensively, which facilitates the users to search the needed webpages, and improve the user experience.
