Abstract

A method and system for providing a query using an image is disclosed. A search keyword is determined using an image and position information of a terminal that are received from the terminal. Search queries associated with the determined search keyword are provided to the terminal. Lower search queries may be provided to the terminal if one of the provided search queries is selected.

Claims

1. A method, using a processor, for providing a query, the method comprising:

receiving at least one image;

receiving position information of a terminal;

determining, by the processor, a search keyword based on the received image and the received position information of the terminal; and

providing at least one search query associated with the determined search keyword.

2. The method of claim 1, further comprising:

receiving a search query selected from the provided at least one search query; and

providing lower search queries corresponding to the selected search query.

3. The method of claim 1, wherein the at least one search query associated with the determined search keyword comprises a real-time rush keyword corresponding to the determined search keyword.

4. The method of claim 1, wherein providing at least one search query comprises:

determining a search scope of the at least one search query associated with the determined search keyword using the received at least one image if the position information of the terminal is received; and

providing the at least one search query according to the determined search scope.

5. The method of claim 1,

wherein receiving at least one image comprises receiving one or more images from the terminal and acquiring one or more images uploaded from the at least one terminal positioned within the reference distance of the terminal, and

wherein determining the search keyword comprises:

detecting an image of the acquired images that matches one of the one or more received images comprising a plurality of images stored in the terminal by comparing the acquired images with the plurality of stored images; and

determining the search keyword based on the detected image.

6. The method of claim 5, wherein determining the search keyword further comprises determining the search keyword using a tag of the detected image.

7. The method of claim 5, wherein determining the at least one search keyword further comprises determining a search keyword based on the received position information of the terminal if an image of the at least one received image that most closely matches one of the plurality of stored images is not detected.

8. The method of claim 7, wherein determining the at least one search keyword further comprises:

acquiring documents uploaded from terminals positioned within a reference distance from the terminal;

detecting common keywords in the acquired documents;

counting a number of the acquired documents comprising the common keywords for each of the common keywords; and

determining, as the search keyword, a common keyword having the highest counted number.

9. A system to provide a query, the system comprising:

a storage device;

an image receiving unit to receive at least one image and position information of a terminal;

a search keyword determination unit stored on the storage device and configured to determine at least one search keyword based on the received at least one image and the received position information of the terminal; and

a query providing unit to provide at least one search query associated with the determined at least one search keyword.

10. The system of claim 9, wherein the query providing unit receives a search query selected from the provided at least one search query, and provides lower search queries corresponding to the received selected search query.

11. The system of claim 9, wherein the query providing unit provides at least one real-time rush search query corresponding to the determined at least one search keyword.

12. The system of claim 9, wherein the query providing unit determines a search scope of the at least one search query associated with the at least one determined search keyword using the detected image if the position information of the terminal is received, and provides the at least one search query within the determined search scope.

13. The system of claim 9, wherein the search keyword determination unit comprises:

an image acquisition unit to acquire images uploaded from terminals positioned within a reference distance of the terminal; and

a detection unit to detect an image of the acquired images that matches the received at least one image comprising a plurality of images stored in the terminal by comparing the acquired images with the plurality of stored images,

wherein the search keyword determination unit determines the at least one search keyword based on the detected image.

14. The system of claim 13, wherein the search keyword determination unit determines the at least one search keyword using a tag of the detected image.

15. The system of claim 13, wherein if an image of the received at least one image that matches the plurality of stored images is not detected, the search keyword determination unit determines the at least one search keyword based on the received position information of the terminal.

16. The system of claim 14, wherein the search keyword determination unit comprises:

a document acquisition unit to acquire documents uploaded from terminals positioned within a reference distance from the terminal;

a common keyword detection unit to detect common keywords in the acquired documents;

a counting unit to count a number of the acquired documents including the common keywords for each of the common keywords; and

a determination unit to determine, as the at least one search keyword, a common keyword having a highest count number.

17. A method for providing a query of a terminal, the method comprising:

transmitting, by the terminal, an image and position information;

receiving at least one search query based on the transmitted image and the position information; and

displaying the received at least one search query,

wherein the at least one search query is determined using a tag of a transmitted image that matches a tag of an image among images uploaded from terminals positioned within a reference distance of the terminal.

18. The method of claim 17, wherein the at least one search query is determined, in part, using at least one common keyword among documents uploaded from the terminals positioned within the reference distance of the terminal.

19. The method of claim 17, further comprising:

transmitting a search query selected from the displayed at least one search query; and

receiving and displaying a lower search query corresponding to the selected search query.
