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: Methods, systems, and apparatuses for generating supply forecasts for advertisement impressions are provided. Supply forecasts for future advertisement inventory are enabled to be determined that match attribute values received from a requester in a query or “contract.” Such supply forecasts may be determined based on cumulative or non-cumulative supply forecast values, and may be determined based on time series of supply forecast values for individual impressions or for blocks of impressions.

Abstract: Disclosed is a system to forecast a supply of online advertising demand contracts having day parting targets. The system may receive an online advertising demand contract having a flight duration and a day parting target. The received online advertising demand contract may be processed by converting the day parting target into an hour-of-week day parting target vector. If a first day of the flight duration would generate a conflict in view of the hour-of-week day parting target vector, then the system may generate a new first day contract for the first day of the flight duration.
