Abstract

A method of operation of a navigation system includes: selecting a search keyword; marking a point of interest as closed with the search keyword; and generating a notification with the point of interest marked as closed for displaying on a device.

Claims

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

selecting, with a control unit, a search keyword;

marking a point of interest as invalid with a search of the search keyword; and

generating a notification with the point of interest marked as invalid for displaying on a device for the point of interest that has moved.

2. The method as claimed in claim 1 further comprising calculating a probability of the point of interest being closed.

3. The method as claimed in claim 1 wherein selecting the search keyword includes selecting a pivot indicator.

4. The method as claimed in claim 1 wherein marking the point of interest includes marking the point of interest as closed based on a latest review.

5. The method as claimed in claim 1 further comprising calculating a time difference between a first arrival time recorded at the point of interest and a second arrival time recorded at a second point of interest away from the point of interest.

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

selecting, with a control unit, a search keyword;

marking a point of interest as invalid with a search of the search keyword; and

generating a notification with the point of interest marked as invalid for displaying on a device for identifying the point of interest as out of business.

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

calculating a probability of the point of interest being closed; and

wherein;

marking the point of interest includes marking the point of interest as closed based on the probability.

8. The method as claimed in claim 6 wherein:

selecting the search keyword includes selecting the search keyword as a pivot indicator; and

marking the point of interest includes marking the point of interest as closed based on the pivot indicator and a neighbor word.

9. The method as claimed in claim 6 wherein marking the point of interest includes marking the point of interest as closed based on a latest review and a previous review.

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

calculating a time difference between a first arrival time recorded at the point of interest and a second arrival time recorded at a second point of interest away from the point of interest; and

wherein;

marking the point of interest includes marking the point of interest as closed if the time difference is less than a time threshold.

11. A navigation system comprising:

a control unit for implementing a select module for selecting a search keyword;

a storage unit for implementing a search module, coupled to the select module, for marking a point of interest as invalid with a search of the search keyword; and

a communication unit for implementing a generate module, coupled to the search module, for generating a notification with the point of interest marked as invalid for displaying on a device for the point of interest that has moved.

12. The system as claimed in claim 11 wherein the search module includes a probability calculation module, coupled to the select module, for calculating a probability of the point of interest being closed.

13. The system as claimed in claim 11 wherein the select module is for selecting a pivot indicator.

14. The system as claimed in claim 11 wherein the search module includes a combine module, coupled to the select module, for marking the point of interest as closed based on a latest review.

15. The system as claimed in claim 11 wherein the search module includes a first reducer module, coupled to the select module, for calculating a time difference between a first arrival time recorded at the point of interest and a second arrival time recorded at a second point of interest away from the point of interest.

16. The system as claimed in claim 11 wherein the generate module is for generating the notification for identifying the point of interest as out of business.

17. The system as claimed in claim 16 wherein the search module includes:

a probability calculation module, coupled to the select module, for calculating a probability of the point of interest being closed; and

a point label module, coupled to the probability calculation module, for marking the point of interest as closed based on the probability.

18. The system as claimed in claim 16 wherein:

the select module is for selecting a pivot indicator; and

the search module includes a review extraction module, coupled to the select module, for marking the point of interest as closed based on the pivot indicator and a neighbor word.

19. The system as claimed in claim 16 wherein the search module includes a combine module, coupled to the select module, for marking the point of interest as closed based on a latest review and a previous review.

20. The system as claimed in claim 16 wherein the search module includes a first reducer module, coupled to the select module, for calculating a time difference between a first arrival time recorded at the point of interest and a second arrival time recorded at a second point of interest away from the point of interest and marking the point of interest as closed if the time difference is less than a time threshold.
