Abstract

Disclosed is a location-based service based on a user point of interest (POI). An electronic device comprises: a processor for generating a database related to a user POI; detecting the user request for information; and an output unit for outputting information based on the user POI database. The user POI can indicate at least one place extracted from the information inputted to the electronic device.

Claims

1. A method for operating an electronic device, the method comprising:

generating a database regarding a user point of interest (POI);

detecting an information request from a user; and

outputting information regarding the user POI based on the database,

wherein the user POI indicates at least one place extracted from information inputted to the electronic device,

wherein the information regarding the user POI comprises description of the user POI by using at least one landmark.

2. The method of claim 1, further comprising:

detecting a user input on the electronic device,

wherein the user input comprises a text input based on text mining or a text input for a navigation destination.

3. The method of claim 2, wherein generating the database regarding the user POI comprises:

detecting a POI corresponding to the user POI;

matching the detected POI with the database regarding the user POI; and

if there is no matching, storing the detected POI in the database.

4. The method of claim 3, wherein the user input comprises a text input based on text mining, further comprising:

matching the detected POI with the database regarding the user POI;

detecting a user POI close to the detected POI;

generating a place description based on the user POI; and

outputting the place description.

5. The method of claim 1, further comprising:

identifying the user POI database;

determining event occurrence at the user POI;

obtaining the user POI and event information; and

outputting the user POI and event information.

16. The method of claim 4, wherein the user input comprises a text input for a navigation destination,

the method further comprising:

determining the navigation route,

determining whether the user POI exists on the route, and

controlling to output map display and direction information based on the user POI on a path.

17. The method of claim 16, further comprising:

if there is no user POI on the navigation route, controlling to output map display and direction information without using the user POI.

18. The method of claim 16, further comprising:

determining event occurrence at a user POI on the path, and

outputting the user POI and event information.

19. The method of claim 16, further comprising:

recognizing a road sign through a camera,

detecting a POI of the recognized sign,

determining a POI corresponding to the route, and

determining the direction information according to the determined POI.

20. The method of claim 16, further comprising:

determining whether a user POI exists only in some section of the route, and selects the some section where the user POI exists,

wherein the direction information is direction information based on the user POI which exists in the some section.

6. An electronic device comprising:

a processor configured to generate a database regarding a user point of interest (POI), and detect an information request from a user; and

an output unit for outputting information regarding the user POI based on the database,

wherein the user POI indicates at least one place extracted from information inputted to the electronic device,

wherein the information regarding the user POI comprises description of the user POI by using at least one landmark.

7. The electronic device of claim 6, wherein the processor detects a user input on the electronic device,

wherein the user input comprises a text input based on text mining or a text input for a navigation destination.

8. The electronic device of claim 7, wherein the processor detects a POI corresponding to the user POI, matches the detected POI with the database, and if there is no matching, stores the detected POI in the database.

9. The electronic device of claim 8, wherein the user input comprises a text input based on text mining, and

the processor matches the detected POI with the user POI database, detects a user POI close to the detected POI, generates a place description based on the user POI, and controls to output the place description.

10. The electronic device of claim 8, wherein the user input comprises a text input for a navigation destination, and

the processor determines the navigation route, determines whether the user POI exists on the route, and controls to output map display and direction information based on the user POI on a path.

11. The electronic device of claim 10, wherein the processor, if there is no user POI on the navigation route, controls to output map display and direction information without using the user POI.

12. The electronic device of claim 6, wherein the processor identifies the user POI database, determines event occurrence at the user POI, obtains the user POI and event information, and controls to output the user POI and event information.

13. The electronic device of claim 10, wherein the processor is further configured to determine event occurrence at a user POI on the path, and output the user POI and event information.

14. The electronic device of claim 10, wherein the processor recognizes a road sign through a camera, detects a POI of the recognized sign, determines a POI corresponding to the route, and determines the direction information according to the determined POI.

15. The electronic device of claim 10, wherein the processor determines whether a user POI exists only in some section of the route, and selects the some section where the user POI exists, and

the direction information is direction information based on the user POI which exists in the some section.
