Abstract: A method and system for ascribing a reputation of an entity as a rater of other entities is provided. A first rating indicative of a rating of a rated entity by the first entity, and one or more second ratings, each second rating indicative of a rating of the rated entity provided by another entity, are provided. The second ratings are combined to produce a first combined rating. The first rating is compared to the first combined rating to produce a first rating predictability of the first rating, the first rating predictability being a negative function of a magnitude of a difference between the first rating and the first combined rating. A resulting rater reputation is generated based at least in part on the first rating predictability.

Abstract: A personalized ratee reputation of a first entity from the perspective of a second entity is determined. The second entity is connected by one or more rating paths to the first entity. A breadth-first search is performed, beginning at the second entity, to determine, from the one or more rating paths, one or more first rating paths that have a first length equal to a shortest length between the first entity and the second entity. For each determined first rating path, a third entity on the first rating path that has a level equal to one less than the first length is identified. For each identified third entity, a first rating of the first entity provided by the third entity determined, and the first ratings are combined. The personalized ratee reputation is then produced by weighting the combined first ratings by an amount according to the first length.

Abstract: A method and system for determining a ratee reputation of an entity based at least in part on the rater reputation of one or more of the entities that have rated the rated entity. A ratee reputation of a first entity is determined. A first rating of the first entity by a second entity is received. One or more rater reputations including a first rater reputation of the second entity as a qualitative rater of other entities are accessed, and a ratee reputation of the first entity is generated by combining the one or more rater reputations and the first rating.
