Methods and apparatus to measure market statistics
First Claim
1. A method to correct data source error, comprising:
- identifying, by executing an instruction with a processor, a first hostname label based on a reverse resolve of an Internet protocol (IP) address corresponding to a household;
parsing the first hostname label to identify a service provider name;
invoking a trace route of the IP address corresponding to the household, the trace route originating from two or more originating IP addresses to identify second and third hostname labels associated with corresponding router last hops, the two or more originating IP addresses different from each other and targeting the same IP address corresponding to the household;
when the second and third hostname labels include a matching location indicator, confirming the service provider name is valid; and
when the first hostname label service provider name matches a service provider name in self reported data, correcting, by executing an instruction with the processor, an error metric of a data source storing the self reported data by adjusting a weight value associated with the self reported data.

Abstract
Example methods and apparatus to measure market statistics are disclosed. A disclosed example method includes identifying, by executing an instruction with a processor, a household including self reported data stored in a data source, retrieving, by executing an instruction with the processor, an Internet protocol (IP) address from the household, identifying, by executing an instruction with the processor, a hostname label based on a reverse resolve of the IP address, determining whether the hostname label matches the self reported data, with the processor, and when the hostname label matches the self reported data, correcting, by executing an instruction with the processor, an error metric of the data source by adjusting a weight value associated with the self reported data.

1. A method to correct data source error, comprising:
-
identifying, by executing an instruction with a processor, a first hostname label based on a reverse resolve of an Internet protocol (IP) address corresponding to a household; parsing the first hostname label to identify a service provider name; invoking a trace route of the IP address corresponding to the household, the trace route originating from two or more originating IP addresses to identify second and third hostname labels associated with corresponding router last hops, the two or more originating IP addresses different from each other and targeting the same IP address corresponding to the household; when the second and third hostname labels include a matching location indicator, confirming the service provider name is valid; and when the first hostname label service provider name matches a service provider name in self reported data, correcting, by executing an instruction with the processor, an error metric of a data source storing the self reported data by adjusting a weight value associated with the self reported data. - View Dependent Claims (2, 3, 4, 5, 6, 15, 16, 17, 18)

7. An apparatus to correct data source error, comprising:
-
a hostname resolver to; identify a first hostname label based on a reverse resolve of an Internet protocol (IP) address corresponding to a household; parse the first hostname label to identify a service provider name; invoke a trace route of the IP address corresponding to the household, the trace route originating from two or more originating IP addresses to identify second and third hostname labels with corresponding router last hops, the two or more originating IP addresses different from each other and targeting the same IP address corresponding to the household; and when the second and third hostname labels include a matching location indicator, confirm the service provider name is valid; and a data source weight calculator to, when the first hostname label service provider name matches a service provider name in self reported data, correct an error metric of a data source storing the self reported data by adjusting a weight value associated with the self reported data. - View Dependent Claims (8, 9, 10, 11, 19, 20, 21, 22)

12. A computer readable storage device or storage disk comprising computer readable instructions that, when executed, cause a processor to at least:
-
identify a first hostname label based on a reverse resolve of an Internet protocol (IP) address corresponding to a household; parse the first hostname label to identify a service provider name; invoke a trace route of the IP address corresponding to the household, the trace route originating from two or more originating IP addresses to identify second and third hostname labels associated with corresponding router last hops, the two or more originating IP addresses different from each other and targeting the same IP address corresponding to the household; when the second and third hostname labels include a matching location indicator, confirm the service provider name is valid; and when the first hostname label service provider name matches a service provider name in self reported data, correct an error metric of a data source storing the self reported data by adjusting a weight value associated with the self reported data. - View Dependent Claims (13, 14, 23, 24, 25, 26)
