Abstract: Systems and methods are described for determining a weighted rating and a relative rating. In some embodiments, a receiving module and rating module are configured to receive an identity of a collector, a list of raters, and a social graph, determine for at least one rater a set of non-intersecting paths between the rater and the collector, calculate capacity values for non-intersecting paths, normalize path values, convert path values to a user weight, and apply the at least one rater's weight to the at least one rater's rating. In some embodiments, a receiving module and rating module are also configured to receive a rating for each of the items rated by the rater, calculate a transformed rating, calculate a relative rating, and assign a relative rating to an item.

Abstract: In one embodiment, program code is added to a social network's web pages or site such that the content a first user accesses is locally stored at the first user's system. When another user, who is a friend of the first user, as defined by the social networking site, browses to that same content, the program code fetches it from the first user, instead of directly from the social networking site. The content is thus directly exchanged between the users without a transaction at the website. The present invention leverages the storage and bandwidth resources of social networking users to help serve content.
