Abstract: A method of processing a supply query is described. The method includes receiving a first supply query comprising a first set of attributes. A size of the first set of attributes is compared to a threshold value. A second supply query comprising a second set of attributes is generated when the comparison indicates that the size of the first set of attributes is greater than the threshold value.

Abstract: A method, system and computer readable medium to adjust impression supply sampling weights in a display advertising environment while providing high-performance supply forecasting using trends adjustments and override rules. A forecasting system initiates the method upon submitting a campaign query (with a campaign query predicate to be matched with impression supply predicates) and a campaign query time period (specifying time-wise aspects of an advertising campaign). Upon receiving initial campaign query results (e.g. impression supply datastructure with base weights), the method proceeds to identify applicable weight adjustment rules for applying to the impression supply node, then, after accounting for trends or other time-wise aspects of the weight adjustment rule, applying the adjustment rule to the impression supply base weight of an impression supply node, resulting in at least one adjusted trend weight.

Abstract: A method of forecasting a supply using data from a plurality of data servers is described. The method includes receiving a request for a supply forecast and sending a query for supply data to a plurality of data servers. The method also includes receiving the supply data from one or more of the plurality of data servers in response to the query. A response level is determined based on the received supply data, and is compared to a threshold level. The method also includes computing the supply forecast based on the received supply data when the response level equals or exceeds the threshold level.
