Ad retrieval for user search on social network sites

摘要

In this invention, systems and methods for providing keywords for advertising are provided. After a user searches for another user in a social network, the webpage or blog of the queried user is retrieved, and keywords are extracted from this webpage. The keywords may be extracted from the user's profile on the social network (e.g., favorite sports, music artists, etc.), or keywords may be extracted from the text of the webpage (e.g., comments that comprise the blog entries). Once extracted, these keywords may then be used by an advertising system to provide targeted advertisements to the user.
