Systems, methods, and computer-readable storage media are provided for conflating entities using a persistent entity index. Information (including attributes) pertaining to a plurality of entities is received. The received information is either matched with one or more existing entities in the persistent entity index or, if no match is found, selected for addition to the persistent entity index. The persistent entity index includes entity-attribute pairs associated therewith. Attributes associated with matching entities for which information is received are aggregated and/or reconciled with the entity-attribute pairs associated with existing entities included in the persistent entity index. The persistent entity index may be incrementally updated at predetermined time intervals to insure the accuracy and freshness of the information associated therewith.

Conflating entities using a persistent entity index

This patent application pertains to answer model comparison. One implementation can determine a first frequency at which an individual answer category appears in an individual slot on a query results page when utilizing a first model. The method can ascertain a second frequency at which the individual answer category appears in the individual slot on the query results page when utilizing a second model. The method can calibrate the second model so that the second frequency approaches the first frequency.
