Such a program module or hardware may be included in the content search result providing server 200 or other device capable of communicating therewith in the form of an operating system, an application program module, and other program modules, and physically stored in various known storage devices. can be Meanwhile, these program modules or hardware include, but are not limited to, routines, subroutines, programs, objects, components, data structures, etc. that perform specific tasks to be described later or execute specific abstract data types according to the present invention.

The location information input interface providing unit 210 provides an interface for inputting location information, which is a content search base, to the user terminal 100 .

According to an embodiment of the present invention, the location information input interface providing unit 210 may provide a location information input window through which location information can be directly input as shown in FIG. 3A . According to an embodiment, when the user terminal 100 does not have a positioning sensor (eg, a desktop or laptop notebook, etc.), an interface as shown in FIG. 3A may be provided. have. That is, when the initial positioning information is not provided from the user terminal 100, a corresponding interface may be provided, but even if the user terminal 100 is provided with a positioning sensor, according to the user's selection, As shown in (a), a location information input window may be provided.

Also, an interface (or button) that enables a voice input may be included in the interface enabling location information input (refer to (a) of FIG. 3). By clicking the corresponding button, the user may input address or place name information by voice through a microphone provided in the user terminal 100, and the corresponding voice is converted into text information or provides the content search result as it is the corresponding voice data may be transmitted to the server 200 .

Meanwhile, according to another embodiment of the present invention, the location information input interface providing unit 210 may provide a map image as shown in FIG. 3B to the user terminal 100 . In this process, the user terminal 100 transmits the initial location information, for example, the current location information acquired by the location positioning sensor it has to the content search result providing server 200, and the location information input interface The providing unit 210 may provide a map image centered on the received location information to the user terminal 100 .

The location information receiving unit 220 receives the location information input by the user from the user terminal 100 through an interface such as (a) or (b) of FIG. 3 .

The user may directly input an address or a place name for a desired search location as text through the interface as shown in FIG. It can also be selected in drop form.

For example, as shown in (a) of FIG. 4 , when a user selects a specific location (eg, “Lotte World”) displayed on the map (by a touch or click method), the specific location is moved around. The scale may be changed so that an area corresponding to a preset radius (eg, 10 km) is enlarged and displayed as shown in FIG. 4B .

In addition, when the user terminal 100 is a terminal such as a smart phone having a touch screen, the user selects a specific area (area A-B) in a touch method as shown in FIG. and, accordingly, the corresponding area (area A-B) may be enlarged and displayed on the map as shown in FIG. 5(b) . The user may specify and select a desired area on the enlarged or reduced map.

According to another embodiment of the present invention, location information of the user terminal 100 obtained through a location detection sensor provided by the user terminal 100 itself, for example, GPS, is transmitted to the location information receiving unit 220 . and the location information receiving unit 220 may transmit a map image of a range corresponding to a predetermined radius around the corresponding location to the user terminal 100 .

At this time, the user performs a drag input from the first point to the second point on the map image displayed on the user terminal 100 as shown in (a) of FIG. You can select an area as a desired search area. The content related to the corresponding region may be provided as a search result due to the selection of the desired region to be searched. In this case, the user performs a search request related to the corresponding region through a drag operation without inputting a search word.

Compared to the existing keyword (search word) input method, the method in which the user drags and enters a map image provided through the user's location information and searches for a video for the region in the search for content, specifically, video It is an intuitive, convenient and effective method.

The content search result providing unit 230 includes content uploaded by other users within a preset radius (5M, 10M, 1KM, etc.) from specific location information directly input by the user through (a) of FIG. 3 , FIG. 4 or The user terminal as a search result by searching for content uploaded by other users within a preset radius (5M, 10M, 1KM, etc.) from the area selected through FIG. 5 or the specific area selected by the user in FIG. 5(b) (100). In this process, altitude information may be used together as location information.

The search target may be contents provided by the contents providing server 300 , and since each contents includes uploaded location information as metadata, the contents search result providing unit 230 searches for contents based on location information. can be performed.

According to an embodiment of the present invention, the search result may be provided in the form of a content list. The list may be displayed including the title and thumbnail of each content, and additionally, upload user information, upload date and time, and feedback scores of other users (number of recommendations such as “likes”, number of comments, etc.) may be displayed together. .

In addition, according to an embodiment of the present invention, as shown in FIG. 6 , contents uploaded in a corresponding region may be displayed for each region on the map. When displaying the content, the title, thumbnail, upload user information, upload date, or feedback score of other users (the number of recommendations such as “likes”, the number of comments, etc.) may be displayed together.

On the other hand, even if a narrow area range is selected by the user, the number of uploaded contents within the area will be very large.

If all contents searched for based on the location information specified by the user are provided as search results, the user will be flooded with information, which may result in a meaningless search service.

Accordingly, according to an embodiment of the present invention, the top N contents (N>0) among the top contents may be provided as a search result by sorting the contents with the highest feedback score of other users among the searched contents. .

The feedback score may be calculated in proportion to the number of recommendations such as “likes” or the number of comments.

In addition, according to another embodiment of the present invention, for contents searched based on location information, the distance from the specific location designated by the user to the content upload location, the uploaded time, and the relevance score between the content and the uploaded location , it is also possible to set priorities by comprehensively considering feedback scores from other users.

For example, the score of each content may be calculated by the following equation.

[Equation 1]

In the above equation, D is a specific location designated by the user (a specific location input by the user in (a) of FIG. 3, a specific location selected by the user in (a) of FIG. 4), or an area selected by the user by dragging in FIG. center position, etc.) and the corresponding content upload location, T is the time interval from the current time to the content upload date, R is the relevance score between the content and the uploaded location, and F is the feedback score from other users.

The content of the content may be determined by referring to at least one of title, content, and tag information registered by the corresponding content uploading user. For example, when the keyword expressed with the highest frequency based on the title, content, and tag information of the content is “Lotte World”, it may be determined that the content of the corresponding content is “Lotte World”.

If the upload location of the corresponding content is "Jamsil-dong", since "Lotte World" is located in "Jamsil-dong", the relevance score (R) between the content of the corresponding content and the uploaded location will be given high.

Meanwhile, in determining the content of the content, a higher score may be given to a keyword included in the tag information than to a keyword included in the content, and a keyword included in the content title than the keyword included in the tag information A higher score is given to , so that the content of the corresponding content can be identified with the keyword with the highest score.

For example, if the title of the content is “Enjoy Lotte World” and the content of the content is “Jamsil Day Trip”, the content of the content will be “Lotte World”.

In addition, in the above equation, when calculating the feedback score (F) by other users, the score can be calculated by giving more weight to the number of comments that can be said to have shown active feedback than clicking “Like”. .

α, β, γ, and δ are weights assigned to each variable, and the sum of these weights may be constantly maintained as a preset value (ex. 1).

In addition, a weight related to a variable to be considered important when calculating the score of each content among the D value, T value, R value, and F value may be set to be relatively high. The weight may be adjusted by the operator of the content search result providing server 200 .

Meanwhile, when the user selects a specific location, for example, when the user inputs a specific address or place name input in FIG. 3A, the value of α may be relatively increased. This is because, when the user inputs a specific address or place name, there is a high possibility that the user wants to check the uploaded content from the specific location. Conversely, when the user selects a region of a specific region as shown in FIG. 5 , a relatively low value of α may be set.

In this way, the content search results based on the region selected by the user are provided, thereby reducing the difficulty of having to consider keywords when searching for content directly from the user's point of view.

In addition, based on the location information, the distance from the location to the content upload location, the uploaded time, the relevance score between the content and the uploaded location, and the feedback score by other users are comprehensively considered, and the Since the content selected by adjusting the weight is preferentially provided as a search result, a content search result that meets the user's needs can be provided.

The foregoing description of the present invention is for illustration, and those of ordinary skill in the art to which the present invention pertains can understand that it can be easily modified into other specific forms without changing the technical spirit or essential features of the present invention. will be. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive. For example, each component described as a single type may be implemented in a distributed manner, and likewise components described as distributed may also be implemented in a combined form.
