Abstract

Content tagging method and apparatus automatically tag points of interest in a portable terminal. The content tagging method in the portable terminal includes determining a search region using current location information when creating content; and searching a Point of Interest (POI) corresponding to the search region from a pre-stored POI list. The searched POI is tagged to the content.

Claims

1. A content tagging method in a portable terminal, comprising:

when creating a content, determining a search region using current location information;

searching a Point of Interest (POI) corresponding to the search region from a stored POI list; and

tagging the searched POI to the content.

2. The content tagging method of claim 1, wherein the search region is determined using at least one of the current location information, a movement speed, and a movement direction of the portable terminal.

3. The content tagging method of claim 2, wherein the search region is determined as a region corresponding to a first radius based on the current location information.

4. The content tagging method of claim 2, wherein, when the movement speed is lower than a threshold, the search region is determined as a region corresponding to a second radius based on the current location information, and when the movement speed is greater than the threshold, the search region is determined as a region corresponding to a third radius based on the current location information,

wherein the second radius is smaller than the third radius.

5. The content tagging method of claim 2, wherein the search region is determined as a partial region corresponding to the movement direction of the portable terminal, in a region corresponding to a preset radius based on the current location.

6. The content tagging method of claim 1, wherein the stored POI list comprises at least one of a POI list registered by a user, a tourist attraction POI list, and a POI list of general geographic features and place names.

7. The content tagging method of claim 1, further comprising:

when a plurality of POIs from the stored POI list exist in the search region, selecting one POI based on a priority and a distance of each POI in the search region.

8. The content tagging method of claim 7, wherein the priority of the POI is changed and set according to a pattern of use by the user.

9. The content tagging method of claim 8, wherein the priority of the POI corresponding to a specific place is changed and set according to whether the specific place is searched or whether the portable terminal stays in the specific place over a certain time.

10. The content tagging method of claim 1, wherein the POI tagged to the content is changeable by the user.

11. A content tagging apparatus in a portable terminal, comprising:

a content generator configured to create a content;

a location information receiver configured to periodically obtain location information of the portable terminal;

a region determiner configured to determine a search region using the current location information;

a storage part configured to store a POI list; and

a Point of Interest (POI) manager configured to search a POI corresponding to the search region from the stored POI list, and tagging the searched POI to the content.

12. The content tagging apparatus of claim 11, wherein the region determiner determines the search region using at least one of the current location information, a movement speed, and a movement direction of the portable terminal.

13. The content tagging apparatus of claim 12, wherein the region determiner determines the search region as a region corresponding to a first radius based on the current location information.

14. The content tagging apparatus of claim 12, wherein, when the movement speed is lower than a threshold, the region determiner determines the search region as a region corresponding to a second radius based on the current location information, and when the movement speed is greater than the threshold, the region determiner determines the search region as a region corresponding to a third radius based on the current location information,

wherein the second radius is smaller than the third radius.

15. The content tagging apparatus of claim 12, wherein the region determiner determines the search region as a partial region corresponding to the movement direction of the portable terminal, in a region corresponding to a preset radius based on the current location.

16. The content tagging apparatus of claim 11, wherein the storage part stores at least one of a POI list registered by a user, a tourist attraction POI list, and a POI list of general geographic features and place names in vicinity.

17. The content tagging apparatus of claim 11, wherein, when a plurality of POIs from the stored POI list exist in the search region, the POI manager selects one POI based on a priority and a distance of each POI in the search region.

18. The content tagging apparatus of claim 17, wherein the POI manager changes and sets the priority of the POI according to a pattern of use by the user.

19. The content tagging apparatus of claim 18, wherein the POI manager changes and sets the priority of the POI corresponding to a specific place according to whether the specific place is searched or whether the portable terminal stays in the specific place over a certain time.

20. The content tagging apparatus of claim 11, wherein the POI tagged to the content is changeable by the user.
