Patent ID: 8874652

Claim:
A computer-implemented method comprising: accessing panel data representing accesses by a first set of users with multiple types of media platforms to media content associated with multiple media entities, the first set of users being included in a sampled panel of users; based on the accessed panel data, determining, for each of multiple media entities, an overlap in the accessed panel data that represents users in the first set of users who have accessed media content associated with the media entity with more than one of the multiple types of media platforms; accessing census data representing accesses by a second set of users with the multiple types of media platforms to media content associated with the multiple media entities, wherein the second set of users includes a greater number of users than the first set of users; based on the accessed panel data, the determined overlap in the accessed panel data, and the accessed census data, deriving, by one or more processors, an overlap function that estimates an overlap in the accessed census data that represents users in the second set of user who have accessed media content associated with a media entity with more than one of the multiple types of media platforms; and applying, by the one or more processors, the derived overlap function to census data associated with a first media entity to estimate an overlap in the census data associated with the first media entity that represents users who have accessed media content associated with the first media entity with more than one of the multiple types of media platforms.
