Abstract

A method and system for assessing the quality of location content is disclosed. The method includes evaluating the quality of location content based on who provided the content, the accuracy of the location data associated with the content, the integrity of the content, and when the content was provided. As a result of the evaluation, a quality score is generated. The quality score provides an indication of the reliability of the location content. The quality score may be updated when a change is made to the content.

Claims

1. A method for assessing quality of location content, comprising:

receiving location content associated with a geographical location from a content source;

analyzing the location content based on variables including who is the location content source, accuracy of geographical location data associated with the location content, what content data is provided in a profile associated with the location content, and when the geographical location data and the content data is provided; and

providing an indication of quality of the location content based on the analysis.

2. The method of claim 1, wherein receiving location content includes receiving data regarding a location via one of a user interface and a Web service.

3. The method of claim 1, wherein analyzing the location content includes using at least one matrix to calculate the who, where, what, and when variables.

4. The method of claim 3, wherein analyzing the location content includes using a set of algorithms associated with the at least one matrix to calculate the who, where, what, and when variables.

5. The method of claim 1, further comprising verifying the content source.

6. The method of claim 5, wherein analyzing the location content includes evaluating how the content source was verified.

7. The method of claim 1, wherein analyzing the location content includes evaluating geospatial accuracy of a location.

8. The method of claim 1, wherein analyzing the location content includes evaluating how much data is located in the profile associated with the location content.

9. The method of claim 1, wherein analyzing the location content includes evaluating what types of data are located in the profile associated with the location content.

10. The method of claim 1, wherein analyzing the location content includes evaluating the accuracy of the data located in the profile associated with the location content.

11. The method of claim 1, wherein analyzing the location content further includes updating the analysis when the location content changes.

12. The method of claim 1, wherein analyzing the location content includes evaluating influences of one variable on another variable.

13. The method of claim 1, wherein providing an indication of quality of the location content includes providing the indication to a requester of the location content.

14. The method of claim 1, wherein providing an indication of quality of the location content includes providing the indication to the content source.

15. The method of claim 1, wherein providing an indication of quality of the location content includes providing a single quality score.

16. The method of claim 1, wherein providing an indication of quality of the location content includes providing a quality score for each of the variables.

17. A system for providing an indication regarding reliability of information provided to the system, comprising:

a user interface that allows a user to provide information regarding a location;

a data store that stores the information regarding the location; and

a content quality system that evaluates the stored location information based on at least four factors and generates at least one quality score associated with the location information, wherein a first factor is associated with who is the user, wherein a second factor is associated with data regarding where the location is geospatially located, wherein a third factor is associated with what information the user provides, and wherein a fourth factor is associated with when the user provided the information.

18. The system of claim 17, further comprising a location referencing system that assigns an identifier to the location that is stored in the data store with the location information.

19. The system of claim 17, further comprising a content delivery server operable to provide the location information and the quality score to a requester of the location information.

20. A method for providing an output representative of data reliability, comprising:

identifying who provided data and calculating an associated who value;

identifying a location associated with the data and calculating an associated where value;

identifying what is the data and calculating an associated what value;

identifying when the data was provided and calculating an associated when value;

using a calculation that accounts for interactions between the calculated who, where, what, and when values; and

providing an output based on the calculation, wherein the output indicates the data reliability.

21. The method of claim 20, wherein identifying who provided the data includes identifying a method used to verify a user that provided the data.

22. The method of claim 20, wherein identifying a location associated with the data includes identifying an accuracy level of geospatial data associated with the provided data.

23. The method of claim 20, wherein identifying what is the data includes identifying an integrity level associated with the provided data.

24. The method of claim 20, wherein identifying when the data was provided includes identifying a time that the data was provided.
