A reputation management system, method and computer readable storage medium assigns reputation scores to various types of entities including, but not limited to people, products, advertisers and merchants. A reputation function is based on a directed graph including the reviewers and the reviews. The nodes in the graph represent the reviewers and the reviews and the links in the graph represent the ratings. The reputation function is iteratively solved until a convergence condition is met. Prior to convergence, when a stability condition is met, the reputation function is modified so as to remove portions of the function corresponding to nodes with negative reputations. Upon convergence, reputation values for at least the reviewers and reviews corresponding to nodes that have not been removed from the reputation function are generated.
