System and Method for Personalized Search While Maintaining Searcher Privacy

摘要

Personalization of Internet search is effected through the use of ResultRank and searcher selected profile attributes and searcher selected query context attributes. These attributes are also referred to as hats (worn by the searcher). Searcher privacy is maintained by allowing limited use of a searcher's profile by the search engine. Query language interpretation is improved by capture and use of searcher behavior and hat selection, in past search sessions, without storage of individual profile or context information. ResultRank is maintained and adjusted, on a per hat basis such that future, similarly hatted searchers benefit from these past sessions. An average of ResultRank, across searcher selected hats, is utilized for improved SERP ranking Recognition of QLP's is improved by use of the hats. Custom support of public and private language community circles is incorporated. The technique is applied to organic as well as sponsored results. Steps are taken to minimize the impact of any attempt to artificially adjust ResultRank.
