Abstract

A method of operation of a navigation system includes: selecting a category of interest; receiving available information for the category of interest; and extrapolating a relative ranking based on the available information for displaying at a device.

Claims

1. A method of operation of a navigation system comprising:

selecting a category of interest;

receiving available information for the category of interest; and

extrapolating a relative ranking based on the available information for displaying at a device.

2. The method as claimed in claim 1 further comprising:

selecting a future time of interest; and

wherein extrapolating the relative ranking based on the available information includes;

generating the relative ranking for the future time of interest based on the available information.

3. The method as claimed in claim 1 further comprising:

selecting an unknown region lacking all or partial data in the available information; and

wherein extrapolating the relative ranking based on the available information includes;

estimating the relative ranking for the unknown region based on the available information.

4. The method as claimed in claim 1 further comprising:

selecting a future time of interest; and

wherein extrapolating the relative ranking based on the available information includes;

generating the relative ranking for the future time of interest based on the available information;

generating an updated version of the available information based on a user generated content for the relative ranking; and

improving an accuracy of the relative ranking based on the updated version.

5. The method as claimed in claim 1 further comprising:

selecting an unknown region lacking all or partial data in the available information; and

wherein extrapolating the relative ranking based on the available information includes;

estimating the relative ranking for the unknown region based on the available information;

generating an updated version of the available information based on a user generated content for the relative ranking at a known region, the unknown region, or a combination thereof; and

improving an accuracy of the relative ranking based on the updated version.

6. A method of operation of a navigation system comprising:

selecting a category of interest;

receiving available information for the category of interest with the available information including current data, historical data, user generated content, or the combination thereof;

selecting a future time of interest, an unknown region lacking all or partial data in the available information, or a combination thereof; and

extrapolating a relative ranking based on the available information with the future time of interest or the unknown region for displaying at a device.

7. The method as claimed in claim 6 wherein:

extrapolating the relative ranking includes selecting a region; and

further comprising;

re-ranking the relative ranking based on the region.

8. The method as claimed in claim 6 wherein:

extrapolating the relative ranking includes selecting a route;

detecting a current location along the route; and

further comprising;

re-ranking the relative ranking based on the current location.

9. The method as claimed in claim 6 further comprising:

selecting a route; and

wherein extrapolating the relative ranking based on the available information with the future time of interest or the unknown region includes;

generating an updated version of the available information based on the user generated content along the route; and

improving an accuracy of the relative ranking for the route based on the updated version.

10. The method as claimed in claim 6 wherein extrapolating the relative ranking based on the available information includes:

selecting a route or a region; and

generating a trend based on the available information for the route or the region.

11. A navigation system comprising:

a user interface for selecting a category of interest;

a storage unit, coupled to the user interface, for receiving available information for the category of interest; and

a control unit, coupled to the storage unit, for extrapolating a relative ranking based on the available information for displaying at a device.

12. The system as claimed in claim 11 wherein:

the user interface is for selecting a future time of interest; and

the control unit is for generating the relative ranking based on the future time of interest and the available information.

13. The system as claimed in claim 11 wherein the control unit includes:

a select navigation module for selecting an unknown region lacking all or partial data in the available information; and

an extrapolation module for estimating the relative ranking for the unknown region based on the available information.

14. The system as claimed in claim 11 wherein:

the user interface includes;

a user input module for selecting a future time of interest,

an available information module for entering a user generated content; and

the control unit includes;

an extrapolation module for generating the relative ranking based on the future time of interest and the available information,

an available information module for generating an updated version of the available information based on the user generated content for the relative ranking, and

an update result module for improving an accuracy of the relative ranking based on the updated version.

15. The system as claimed in claim 11 wherein the control unit includes:

a select navigation module for selecting an unknown region lacking all or partial data in the available information;

an extrapolation module for estimating the relative ranking for the unknown region based on the available information;

an available information module for generating an updated version of the available information based on a user generated content for the relative ranking at a known region, the unknown region, or a combination thereof; and

an update result module for improving an accuracy of the relative ranking based on the updated version.

16. The system as claimed in claim 11 further comprising:

the storage unit is for receiving available information including current data, historical data, user generated content, or the combination thereof;

the user interface is for selecting a future time of interest, an unknown region, or a combination thereof; and

the control unit is for extrapolating the relative ranking based on the available information with the future time of interest or the unknown region.

17. The system as claimed in claim 16 wherein the control unit includes:

a select navigation module for selecting a region; and

a re-ranking module for re-ranking the relative ranking based on the region.

18. The system as claimed in claim 16 further comprising:

a location unit for detecting a current location; and

wherein the control unit includes;

a select navigation module for selecting a route that includes the current location; and

a re-ranking module for re-ranking the relative ranking based on the current location.

19. The system as claimed in claim 16 wherein the control unit includes:

a select navigation module for selecting a route;

an available information module for generating an updated version of the available information based on the user generated content along the route; and

an update result module for improving an accuracy of the relative ranking for the route based on the updated version.

20. The system as claimed in claim 16 wherein the control unit includes:

a select navigation module for selecting a route or a region; and

an extrapolation module for generating a trend based on the available information for the route or the region.
