Audience duplication for parent-child resource pairs
View Patent ↗A combined reach can be determined for multiple resources. Usage data, including audience duplication data, is used to generate audience duplication measurements for pairs of the resources. A child-resource pair is identified, and the audience duplication measurement for that resource pair is modified. The modified measurement is used to determine a combined reach for the multiple resources. A report is also generated based on the combined reach.
1. A computer-implemented method comprising:
accessing, by one or more processors, usage data that indicates accesses to a plurality of different resources by one or more members of an audience with one or more client systems and includes information usable in determining audience duplication across one or more of the plurality of different resources;
determining, by the one or more processors, that at least one pair of resources in the plurality of different resources is a correlated resource pair, wherein the correlated resource pair includes two resources (i) with a correlation such that the two resources exhibit covariance, and (ii) have a predetermined taxonomic relationship that is separate from the accessed usage data;
in response to determining that at least one pair of resources is a correlated resource pair, determining, by the one or more processors, an audience duplication measurement associated with the correlated resource pair;
determining, by the one or more processors, a combined reach representing a number of accesses of at least one resource within a collection of resources including the plurality of different resources by unique members of the audience based at least on the usage data and the audience duplication measurement; and
generating, by the one or more processors, a report based on the combined reach.
2. The computer-implemented method of claim 1 , wherein the information usable in determining audience duplication included in the accessed usage data is correlation data calculated between each pair of the plurality of different resources, and wherein the audience duplication measurement associated with the parent-child resource pair is a pairwise correlation coefficient for a correlated resource pair.
3. The computer-implemented method of claim 2 , wherein determining the pairwise correlation coefficient for the correlated resource pair comprises multiplying the pairwise correlation coefficient by a factor based on a ratio between usage of a first resource of the correlated resource pair and usage of a second resource of the correlated resource pair.
4. The computer-implemented method of claim 3 , wherein the factor is proportional to (1−p c /p p ), wherein p c is the usage of the first resource and p p is the usage of the second resource.
5. The computer-implemented method of claim 3 , further comprising calculating an adjusted combined reach based on a product of a measured unique audience for each of the plurality of different resources multiplied by an adjustment factor, the adjustment factor being calculated using the determined pairwise correlation coefficients.
6. The computer-implemented method of claim 1 , wherein determining that the correlation exists comprises identifying that the audience duplication of usage of the correlated resource pair is equal to usage of a first resource of the correlated resource pair.
7. The computer-implemented method of claim 1 , wherein the correlated resource pair comprises one or more websites, and wherein one resource of the correlated resource pair comprises one or more of the websites of the other resource of the correlated resource pair and one or more other websites.
8. The computer-implemented method of claim 1 , wherein the plurality of different resources are hosted on servers, and wherein the one or more members of the audience access the plurality of different resources using client systems that send requests for the plurality of different resources to the servers across a network.
9. A system comprising:
one or more computers and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
accessing, by one or more processors, usage data that indicates accesses to a plurality of different resources by one or more members of an audience with one or more client systems and includes information usable in determining audience duplication across one or more of the plurality of different resources;
determining, by the one or more processors, that at least one pair of resources in the plurality of different resources is a correlated resource pair, wherein the correlated resource pair includes two resources (i) with a correlation such that the two resources exhibit covariance, and (ii) have a predetermined taxonomic relationship that is separate from the accessed usage data;
in response to determining that at least one pair of resources is a correlated resource pair, determining, by the one or more processors, an audience duplication measurement associated with the correlated resource pair;
determining, by the one or more processors, a combined reach representing a number of accesses of at least one resource within a collection of resources including the plurality of different resources by unique members of the audience based at least on the usage data and the audience duplication measurement; and
generating, by the one or more processors, a report based on the combined reach.
10. The system of claim 9 , wherein the information usable in determining audience duplication included in the accessed usage data is correlation data calculated between each pair of the plurality of different resources, and wherein the audience duplication measurement associated with the parent-child resource pair is a pairwise correlation coefficient for a correlated resource pair.
11. The system of claim 9 , wherein determining the pairwise correlation coefficient for the correlated resource pair comprises multiplying the pairwise correlation coefficient by a factor based on a ratio between usage of a first resource of the correlated resource pair and usage of a second resource of the correlated resource pair.
12. The system of claim 11 , wherein the factor is proportional to (1−p c /p p ), wherein p c is the usage of the first resource and p p is the usage of the second resource.
13. The system of claim 11 , wherein the instructions are further operable, when executed by the one or more computers, to cause the one or more computers to perform the operation of calculating an adjusted combined reach based on a product of a measured unique audience for each of the plurality of different resources multiplied by an adjustment factor, the adjustment factor being calculated using the determined pairwise correlation coefficients.
14. The system of claim 9 , wherein determining that the correlation exists comprises identifying that the audience duplication of usage of the correlated resource pair is equal to usage of a first resource of the correlated resource pair.
15. The system of claim 9 , wherein the correlated resource pair comprises one or more web sites, and wherein one resource of the correlated resource pair comprises one or more of the websites of the other resource of the correlated resource pair and one or more other websites.
16. The system of claim 1 , wherein the plurality of different resources are hosted on servers, and wherein the one or more members of the audience access the plurality of different resources using client systems that send requests for the plurality of different resources to the servers across a network.
17. A non-transitory computer-readable medium storing software comprising instructions executable by one or more computers which, upon such execution, cause the one or more computers to perform operations comprising:
accessing, by one or more processors, usage data that indicates accesses to a plurality of different resources by one or more members of an audience with one or more client systems and includes information usable in determining audience duplication across one or more of the plurality of different resources;
