1. A method executed by a computer system for determining a value for an attribute of a map feature, the method comprising:
- receiving, from a source, a proposed value for the attribute of the map feature;
determining, by a reliability engine, for the source, a first score indicative of a probability that the source provides intentionally incorrect values, the first score based on a plurality of stored interactions of the source with a map editing service;
determining, by an accuracy engine, for the source, a second score indicative of a probability that the source provides accurate values;
determining, by the reliability engine, for the proposed value, a third score indicative of a probability that the proposed value is an intentionally incorrect value;
determining, by a consensus engine, for the proposed value, a fourth score indicative of the probability that the proposed value is correct based on the first, second and third scores;
determining, by an automoderation engine, a popularity of the map feature;
responsive to the fourth score exceeding a threshold determined responsive to the popularity of the map feature, accepting, by the automoderation engine, the proposed value for the attribute of the map feature, wherein the threshold is higher if the popularity of the map feature is higher;
identifying, by an overclustering engine, one or more characteristics indicative of overclustering with respect to the map feature, the one or more characteristics including a plurality of accepted proposed values for the attribute of the map feature; and
determining by the overclustering engine, a priority associated with the map feature for correcting the overclustering, based at least in part on the one or more characteristics.

1. A method executed by a computer system for determining a value for an attribute of a map feature, the method comprising:
-
receiving, from a source, a proposed value for the attribute of the map feature; determining, by a reliability engine, for the source, a first score indicative of a probability that the source provides intentionally incorrect values, the first score based on a plurality of stored interactions of the source with a map editing service; determining, by an accuracy engine, for the source, a second score indicative of a probability that the source provides accurate values; determining, by the reliability engine, for the proposed value, a third score indicative of a probability that the proposed value is an intentionally incorrect value; determining, by a consensus engine, for the proposed value, a fourth score indicative of the probability that the proposed value is correct based on the first, second and third scores; determining, by an automoderation engine, a popularity of the map feature; responsive to the fourth score exceeding a threshold determined responsive to the popularity of the map feature, accepting, by the automoderation engine, the proposed value for the attribute of the map feature, wherein the threshold is higher if the popularity of the map feature is higher; identifying, by an overclustering engine, one or more characteristics indicative of overclustering with respect to the map feature, the one or more characteristics including a plurality of accepted proposed values for the attribute of the map feature; and determining by the overclustering engine, a priority associated with the map feature for correcting the overclustering, based at least in part on the one or more characteristics. - View Dependent Claims (2, 3, 4, 5, 6)
