Abstract: Recommended Web sites are presented in response to a user visit to a Web site, a history of previous user visits to Web sites, or a user-initiated search query. The Web sites that are recommended are those deemed most similar to the subject Web site or to the results of the search query, as appropriate. Information regarding Web sites is retrieved from locations within a distributed system as identified by a distributed hash table and similarity assessments between the subject Web site or query responses and those Web pages may be made according to that information, as periodically updated.
