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 search query, the method comprising:

receiving at least one image from a user terminal;

comparing the at least one image with a plurality of stored images;

determining whether there is a match between the received image and at least one of the plurality of stored images;

determining a search keyword when the match is detected between the received image and at least one of the plurality of stored images based on the match determination;

receiving location information of the user terminal when no match is detected between the received image and one of the plurality of stored images after the match determination;

acquiring textual documents uploaded by users of other terminals located within a reference distance from the user terminal based on the received location information;

detecting keywords commonly appearing at least a predetermined number of times in each of at least two of the acquired documents;

determining, by the processor, a search keyword based on the commonly appearing keywords, the determined search keyword being associated with at least one topic related to the location information;

providing, to the user terminal, at least one search query associated with the determined search keyword based on the match between the received image and the at least one of the plurality of stored images when the match is detected, and based on the commonly appearing keywords when no match is detected based on the match determination, wherein the at least one search query associated with the determined search keyword based on the commonly appearing keywords is used to search for additional information about the at least one topic in a search engine;

displaying, on a display of the user terminal, the at least one search query, and enabling a user of the user terminal to select one of the at least one search query displayed on the display for a search conducted in the search engine, without the user entering a search keyword in text in the user terminal;

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

providing lower search queries corresponding to the selected search query;

wherein the at least one search query associated with the determined search keyword based on the detection of the match or on the commonly appearing keywords comprises a real-time rush keyword corresponding to the determined search keyword based on the detection of the match or on the commonly appearing keywords.

2. The method of claim 1, wherein determining the search keyword based on the detection of the match comprises determining the search keyword using a tag of the at least one of the plurality of stored images matched with the received image.

3. The method of claim 1, wherein determining the at least one search keyword based on the commonly appearing keywords comprises:

counting a number of the acquired documents having the commonly appearing keywords for each of the commonly appearing keywords; and

determining, as the search keyword, a commonly appearing keyword appearing in the highest counted number of acquired documents.

4. A system to provide a search query, the system comprising:

a storage device; and

a processor for executing functions of a plurality of function units stored in the storage device, the function units including,

an image receiving unit configured to receive at least one image from a user terminal;

an image detection unit for comparing the at least one image with a plurality of stored images, and determining whether there is a match between the received image and at least one of the plurality of stored images;

a determination unit configured to determine a first search keyword when the match is detected between the received image and the at least one of the plurality of stored images based on the match determination by the image detection unit;

a document acquisition unit for receiving location information of the user terminal when no match is detected between the received image and the at least one of the plurality of stored images after the match determination by the image detection unit, and acquiring textual documents uploaded by users of other terminals located within a reference distance from the user terminal based on the received location information;

a common keyword detection unit configured to detect keywords commonly appearing at least a predetermined number of times in each of at least two of the acquired documents;

wherein the determination unit is further configured to determine a second search keyword based on the commonly appearing keywords when no match is detected based on the match determination, the determined second search keyword being associated with at least one topic related to the location information; and

a query providing unit configured to provide at least one search query associated with the determined first or second search keyword, the at least one search query associated with the second search keyword being determined and used to search for additional information about the at least one topic in a search engine;

wherein the at least one search query is displayed on a display of the user terminal and enables a user of the user terminal to select one of the at least one search query displayed on the display for a search conducted in the search engine, without the user entering a search keyword in text in the user terminal;

wherein the query providing unit is configured to receive a search query selected at the user terminal by the user from the provided at least one search query, and to provide lower search queries corresponding to the received selected search query; and

wherein the query providing unit is configured to provide at least one real-time rush search query corresponding to the determined at least one of the first and second search keywords.

5. The system of claim 4, wherein the determination unit is configured to determine the first search keyword based on the detection of the match, using a tag of the at least one of the plurality of stored images matched with the received image.

6. The system of claim 5, further comprising:

a counting unit configured to count a number of the acquired documents having the commonly appearing keywords for each of the commonly appearing keywords;

wherein the determination unit is configured to determine, as the second search keyword, a keyword appearing in a highest number of documents.
