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.
