Systems and methods for determining relevance ratings for keywords associated with content are disclosed. A quantitative degree of relevance of keywords for a piece of content is determined by querying several reviewers. System users have a keyword record listing the keywords associated with content that a user has exhibited a threshold of interest in. Moreover, a cumulative value for the keywords is maintained by adding the degree of relevance of content keywords to the cumulative value of the keyword in the user's record. By finding correspondences between keywords in a user's record and keywords for pieces of content, advertisements, or other people using the system, a user's interest may be determined, and recommendations for content, advertisements, and potential friends or business contacts may be made to the user.
