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.

Claims

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.

2. A method as defined in claim 1, wherein the matching location indicator includes at least one of a city name or a state name.

3. A method as defined in claim 1, wherein adjusting the weight value further includes increasing the weight value in response to identifying a match between the first hostname label service provider name from the reverse resolve and the service provider name in the self reported data.

4. A method as defined in claim 1, wherein adjusting the weight value further includes decreasing the weight value in response to identifying a dissimilarity between the first hostname label service provider name from the reverse resolve and the service provider name in the self reported data.

5. A method as defined in claim 1, further including calculating a service provider flow share based on the adjusted weight value and a service penetration value from a managed data source.

6. A method as defined in claim 1, further including identifying a household service provider change by comparing the first hostname label at a first time with a fourth hostname label based on a second reverse resolve of the IP address at a second time.

15. A method as defined in claim 1, wherein the second and third hostname labels include two or more matching location indicators.

16. A method as defined in claim 1, further including determining whether the IP address from the household is active or inactive.

17. A method as defined in claim 16, wherein determining that the IP address is active includes:

transmitting an echo request packet to the IP address; and

in response to receiving a reply message from the IP address, determining that the IP address is active.

18. A method as defined in claim 17, wherein when the IP address blocks the echo request packet, determining the IP address is active by scanning one or more ports of a machine associated with the IP address.

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.

8. An apparatus as defined in claim 7, wherein the matching location indicator includes at least one of a city name or a state name.

9. An apparatus as defined in claim 7, wherein the data source weight calculator is to, when adjusting the weight value, increase the weight value in response to identifying a match between the first hostname label service provider name from the reverse resolve and the service provider name in the self reported data.

10. An apparatus as defined in claim 7, wherein the data source weight calculator is to, when adjusting the weight value, decrease the weight value in response to identifying a dissimilarity between the first hostname label service provider name from the reverse resolve and the service provider name in the self reported data.

11. An apparatus as defined in claim 7, further including a test manager to calculate a service provider flow share based on the adjusted weight value and a service penetration value from a managed data source.

19. An apparatus as defined in claim 7, wherein the second and third hostname labels include two or more matching location indicators.

20. An apparatus as defined in claim 7, further including a ping manager to determine whether the IP address from the household is active or inactive.

21. An apparatus as defined in claim 20, wherein to determine that the IP address is active, the ping manager is to:

transmit an echo request packet to the IP address; and

in response to receiving a reply message from the IP address, determine that the IP address is active.

22. An apparatus as defined in claim 21, wherein when the echo request packet is blocked, the ping manager is to scan one or more ports of a machine associated with the IP address to determine the IP address is active.

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.

13. A computer readable storage device or storage disk as defined in claim 12, wherein the instructions, when executed, cause the processor to calculate a service provider flow share based on the adjusted weight value and a service penetration value from a managed data source.

14. A computer readable storage device or storage disk as defined in claim 12, wherein the instructions, when executed, cause the processor to identify a household service provider change by comparing the first hostname label at a first time with a fourth hostname label based on a second reverse resolve of the IP address at a second time.

23. A computer readable storage device or storage disk as defined in claim 12, wherein the second and third hostname labels include two or more matching location indicators.

24. A computer readable storage device or storage disk as defined in claim 12, wherein the instructions, when executed, cause the processor to determine whether the IP address from the household is active or inactive.

25. A computer readable storage device or storage disk as defined in claim 24, wherein the instructions, when executed, cause the processor to:

transmit an echo request packet to the IP address; and

in response to receiving a reply message from the IP address, determine that the IP address is active.

26. A computer readable storage device or storage disk as defined in claim 25, wherein the instructions, when executed, cause the processor to, when the IP address blocks the echo request packet, scan one or more ports of a machine associated with the IP address to determine the IP address is active.
