Abstract

A semantic labeling apparatus and method thereof include a place identifier processor configured to, based on location data of a user, generate place attributes of places that indicate information of a user visit for each place, wherein user location remains unchanged within the places for a predetermined period of time. A group identifier processor is configured to cluster the places based on the place attributes, classify the places into groups, acquire a semantic label for each of the groups, and designate the acquired semantic label as the semantic label of each of the groups. A label determiner is configured to determine the semantic label of each of the groups as a semantic label of each member place of each of the groups.

Claims

1. A semantic labeling apparatus, comprising:

a place identifier processor configured to, based on location data of a user, generate place attributes of places that indicate information of a user visit for each place, wherein user location remains unchanged within the places for a predetermined period of time;

a group identifier processor configured to cluster the places based on the place attributes, classify the places into groups, acquire a semantic label for each of the groups, and designate the acquired semantic label as the semantic label of each of the groups; and

a label determiner configured to determine the semantic label of each of the groups as a semantic label of each member place of each of the groups.

2. The semantic labeling apparatus of claim 1, wherein the location data is detected by a sensor built in a mobile device.

3. The semantic labeling apparatus of claim 2, wherein the location data further comprises at least one of

a geographical user location, an application type operated in the mobile device, a number of incoming or outgoing calls performed by the mobile device, a number of incoming or outgoing short message services (SMS), and behaviors of the user detected by a motion sensor built-in the mobile device.

4. The semantic labeling apparatus of claim 1, wherein the place attributes comprise identification information to distinguish between places and time information on a place of the places the user visits.

5. The semantic labeling apparatus of claim 4, wherein the place attributes further comprise information based on the time information on the place the user visits.

6. The semantic labeling apparatus of claim 5, wherein the place attributes further comprise information indicating an operating state of a mobile device of the user within the place.

7. The semantic labeling apparatus of claim 5, wherein the place attributes further comprise information indicating user behaviors performed in the place and detected by a mobile device.

8. The semantic labeling apparatus of claim 1, wherein the group identifier processor is configured to select, as a representative place, one member place of each of the groups, acquire a semantic label of the selected representative place from the user, and designate the acquired semantic label of the representative place as the semantic label of each of the groups.

9. The semantic labeling apparatus of claim 8, wherein the group identifier processor is configured to select the one member place of each of the groups as the representative place based on the place attributes of member places.

10. The semantic labeling apparatus of claim 8, wherein the group identifier is configured to select the one member place of each of the groups as the representative place based on information related to the user visit among the place attributes of member places of each of the groups.

11. A semantic labeling method, comprising:

generating, based on location data of a user, place attributes of places that indicate information of a user visit for each place, wherein user location remains unchanged within the places for a predetermined period of time;

clustering the places based on the place attributes, classifying the places into groups, acquire a semantic label for each of the groups, and designating the acquired semantic label as the semantic label of each of the groups; and

determining the semantic label of each of the groups as a semantic label of each member place of each of the groups.

12. The semantic labeling method of claim 11, wherein the location data is detected by a sensor built in a mobile device.

13. The semantic labeling method of claim 12, wherein the location data further comprises at least one of

a geographical user location, an application type operated in the mobile device, a number of incoming or outgoing calls performed by the mobile device, a number of incoming or outgoing short message services (SMS), and behaviors of the user detected by a motion sensor built in the mobile device.

14. The semantic labeling method of claim 11, wherein the place attributes comprise identification information to distinguish between places and time information on a place of the places the user visits.

15. The semantic labeling method of claim 14, wherein the place attributes further comprise information based on the time information on the place the user visits.

16. The semantic labeling method of claim 15, wherein the place attributes further comprise information indicating an operating state of a mobile device of the user within the place.

17. The semantic labeling method of claim 15, wherein the place attributes further comprise information indicating user behaviors performed in the place and detected by a mobile device.

18. The semantic labeling method of claim 11, further comprising:

selecting, as a representative place, one member place of each of the groups, acquiring a semantic label of the selected representative place from the user, and designating the acquired semantic label of the representative place as the semantic label of each of the groups.

19. The semantic labeling method of claim 18, further comprising:

selecting the one member place of each of the groups as the representative place based on the place attributes of member places.

20. The semantic labeling method of claim 18, further comprising:

selecting the one member place of each of the groups as the representative place based on information related to the user visit among the place attributes of member places of each of the groups.

21. A non-transitory computer readable medium configured to control a processor to perform the semantic labeling method of claim 11.
