Method and system for ascribing a reputation to an entity as a rater of other entities

DETAILED DESCRIPTION The Sporas reputation mechanism described in the Zacharia thesis uses a single reputation value to represent the reputation of an entity both as a ratee and a rater.
This single reputation represents the reputation of an entity as a combination of ratings provided by other entities, but does not provide an indication of the reputation or trustworthiness of an entity as a rater of other entities.
Thus, an entity may receive high ratings from other entities and thus have a high single-valued reputation, although the entity is a poor rater of other entities and thus should not truly have a high reputation as a rater of other entities.
As used herein, a "rater reputation" of an entity is a reputation or trustworthiness of the entity as a rater of one or more other entities, and a "ratee reputation" of an entity is the reputation of the entity according to the ratings of the entity provided by one or more other entities.
Therefore, Sporas does not provide a method or system for determining and maintaining a rater reputation of an entity.
Accordingly, provided herein is a method and system for determining a rater reputation of an entity.
Further, provided is a method and system for determining a ratee reputation of an entity based at least in part on the rater reputations of one or more of the entities that have rated the rated entity.
In one embodiment, a rater reputation of a first entity as a rater of other entities is determined.
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
