Abstract: Systems and methods of the present disclosure can provide an improved user experience on client devices selecting to receive context-based third-party content by reducing the number of third-party content items presented for display on such client devices. A data processing system can be configured to employ an auction mechanism with selection criterion thresholds (such as minimum bid values) that result, when used in auctions, in enforcing a limit on the amount of third-party content presented for display on client devices that have selected to receive context-based third-party content. The selection criterion thresholds can result, when used in auctions, in enforcing minimum revenues for publishers. The selection criterion thresholds can be determined offline based on historical statistical parameters.

Abstract: Survey accuracy of small sample sizes may be amplified by including, excluding, or weighting survey responses of respondents responsive to characteristics of the respondent being correlated with or not correlated with characteristics of the population determined from aggregated behavioral histories of the population, resulting in favoring survey results of individuals that are truly representative of the larger population and excluding results from outliers. Search queries from devices in a particular region may be aggregated to identify common searches, building a model of characteristics of the regional population without requiring any private or confidential data of the population.
