In addition, the user terminal 10 may be provided with contents from a content providing service provided by the content providing server 20 to be described later.

Meanwhile, the content providing server 20 is an information processing apparatus connected to the user terminal 10 and the network N to transmit and receive data, and provide a content providing service to the user terminal 10.

When the content providing server 20 receives a content request from the user terminal 10, the user acquires the location information of the user to limit the location of the user by using the location information of the user, the environment information at the current location of the user, By selecting content belonging to a category corresponding to personal information, interest information, and the like, the selected content is provided to the user terminal 10. Detailed description of the geohash information will be described later.

Hereinafter, the configuration of the content providing server 20 will be described in more detail.

2 is a functional block diagram showing a content providing server of a calculation target specific system according to an embodiment of the present invention. As shown in FIG. 2, the content providing server 20 may include a location information acquisition unit 21.

The location information acquisition unit 21 obtains location information of an arbitrary user terminal 10. That is, the location information acquisition unit 21 receives the current location information of the user terminal 10 from the user terminal 10, or the GPS information of the user terminal 10, the identification ID of the network equipment retrieved from the user terminal 10 Location information may be obtained using at least one of information and mobile IP (Internet Protocol) address information of the user terminal 10.

In this case, the location information acquisition unit 21 may send a notification for obtaining location information of the user terminal 10 to the user terminal 10. That is, the location information acquisition unit 21 may send a push message to the user terminal 10 for obtaining location information of the user terminal 10 at a predetermined time. In addition, the user terminal 10 may provide the location information calculated when the notification is received to the content providing server 20.

For example, the user terminal 10 is installed with an application programmed to deliver location information to the content providing server 20 upon receiving a notification from the content providing server 20, and thus the user terminal 10. When installed in the application may receive the push message may transmit the location information of the user terminal 10 to the content providing server 20.

In addition, when the preset time arrives, the user terminal 10 may calculate the location of the user to obtain location information, and transfer the obtained location information to the location information acquisition unit 21 of the content providing server 20. That is, the user terminal 10 may check the current position of the user by the position collecting means when the preset time arrives, and transmit the confirmed position information to the position information acquisition unit 21.

Accordingly, the location information acquisition unit 21 may receive the current location information of the user terminal 10 from the user terminal 10.

On the other hand, the position information acquisition unit 21 may obtain the analysis position information calculated based on the past position information of the user corresponding to the user terminal 10. The location information of the past is the location information acquired in the past from the user terminal 10. The current location is periodically received and accumulated from the user terminal 10. May be a location. In addition, the past location information of the user may be the location information of the user referring to the transaction history of the object corresponding to the content provided by the content providing server 20.

The location information acquisition unit 21 may acquire the location information of interest selected by the user corresponding to the user terminal 10. For example, if the user selects 'Samsung-Dong' as the location of interest, the user may obtain location information of the Samsung-Dong.

In addition, the content providing server 20 according to an embodiment of the present invention includes a content extraction unit 22.

Meanwhile, the content extraction unit 22 may limit the range in which the location of the user terminal 10 is included using the location information of the user terminal 10 acquired by the location information acquisition unit 21.

In this case, the content extraction unit 22 may obtain geohash information indicating the location of the user terminal 10 based on the location information of the user terminal 10. In this regard, geohash information refers to information obtained by processing a latitude and longitude value of a corresponding position and expressing the latitude and longitude code of 32 digits. In other words, the geo-hash information is expressed by information corresponding to the position information of the user terminal 10 by converting the latitude and longitude value representing the position information of the user terminal 10 into a 32-digit latitude and longitude code.

The 32-digit number in the geo-hash information can be more precisely specified by referring to more digits from the first digit, that is, when all 32 digits are used. The range can be limited, and as the number of digits referred to is increased, more specific location range can be defined.

In addition, the content extraction unit 22 may identify the cell to which the position of the user terminal 10 belongs by checking the geohash information corresponding to the position information of the user terminal 10 from the first digit to the predetermined N th digit.

The content extraction unit 22 may check the geohash information of the user terminal 10 to check the cell to which the user terminal 10 belongs, and extract the target content belonging to the adjacent cell.

In this case, the target content refers to content that is to be determined whether to be provided to the user among a plurality of previously stored contents. That is, the target content refers to the content calculated by the content selection unit 23 to be described later.

Here, the content is unit data including data related to an object provided to or traded to a user, and may include text, an image, and a video introducing an object traded or introduced in an online space.

3 is a diagram illustrating a cell to which a user terminal belongs by checking the geohash information of the user terminal and displaying a cell to which the user terminal belongs.

As shown in FIG. 3, it is assumed that the content extraction unit 22 confirms the geohash information indicating the position of the user terminal 10 from the first digit to the predetermined ninth digit. It can be seen that the position of the user 10 indicated by the geohash information up to is located in the cell “E”.

Therefore, the content extraction unit 22 may extract the target content having a position adjacent to the range including the position of the user terminal 10. In this case, the location information may be stored in association with each target content, and the location information may include geohash information.

Therefore, the content extraction unit 22 may extract the target content from the cell "E" indicating the position of the user terminal 10 as shown in FIG.

If the content extraction unit 22 checks the geo-hash information indicating the position of the user terminal 10 to the Nth digit and the number of extracted target contents exceeds the predetermined number, the number of the target contents becomes less than or equal to the predetermined number. Until the number of geohash information is added one by one, the process of checking the number of target contents to be extracted can be repeated.

That is, the content extraction unit 22 gradually expands the geohash information of the user terminal 10 from the first digit to N + 1, N + 2 ... up to the 32 digit, and thus the range of the cell to which the user terminal 10 belongs. Can be reduced.

On the other hand, if the number of extracted target contents is less than the predetermined number by checking the geohash information indicating the position of the user terminal 10 to the Nth digit, the number of digits of the geohash information is determined until the number of the target contents becomes more than the predetermined number. The process of checking the number of target contents to be extracted by removing one by one can be repeated.

That is, the content extracting unit 22 extracts the geohash information of the user terminal 10 from the first digit to N-1, N-2... As shown in the figure, the range of cells to which the user terminal 10 belongs can be enlarged gradually.

In addition, the content extraction unit 22 may identify a cell adjacent to the cell to which the user terminal 10 belongs, and may limit content belonging to a cell to which the user terminal 10 belongs and a cell adjacent to the cell to the target content. That is, when the cell to which the position of the user terminal 10 belongs is "E" as shown in FIG. 3, the content extraction unit 22 includes the remaining eight cells surrounding the cell "E" and the cell "E", that is, " Each content belonging to A ”,“ B ”,“ C ”,“ D ”,“ F “,“ G ”,“ H ”, and“ I ”cells can be limited to the target content. That is, the contents belonging to the cells “A”, “B”, “C”, “D”, “E”, “F“, “G”, “H”, and “I” can be limited to the target content.

As such, the content extraction unit 22 may extract the target content based on the location of the user, and in another embodiment, may extract the target user to receive the content based on the location of one content. That is, the content extraction unit 22 may provide content by extracting a target user belonging to a cell adjacent to the cell to which the content belongs.

Content providing server 20 according to an embodiment of the present invention may include a content selection unit (23).

The content selection unit 23 may calculate a distance between the user terminal 10 and the target content extracted by the content extraction unit 22, and select only content having a predetermined distance within the predetermined distance. In this case, the predetermined distance may be set differently for each category of the content or may be set differently according to the content density within a certain range based on the location information of the user terminal 100.

To this end, location information corresponding to the content may be associated and stored in each content. The distance between the user terminal 10 and the content calculated by the content selection unit 23 may be a distance of a straight line or a shortest path. For example, the content selection unit 23 may be calculated by applying a weight to a feature such as a bridge, a tunnel, and the like, in the moving path of the content and the user terminal 10 to be farther than the actual distance.

In addition, the content selection unit 23 may select only content belonging to a category corresponding to the usage history information based on the usage history information of the user terminal 10 among the target content extracted by the content extraction unit 22.

That is, the content selection unit 23 collects the usage history information including at least one of the information of the application installed in the user terminal 10, the usage time information of each application, and the connection frequency information of each application, and the usage history information. Content belonging to a category corresponding to may be selected. For example, when a user uses a lot of applications related to shopping, the content selector 23 may select content belonging to a shopping mall category.

The content selection unit 23 corresponds to environmental information including at least one of geographic information, current weather information, and current time information corresponding to the current location of the user terminal 10 among the contents extracted by the content extraction unit 22. Content belonging to a category can be selected.

The category may be classified according to the content of an object represented by each content, and may be classified according to, for example, whether an object corresponding to the content is a product or a service, or may be classified according to an industry corresponding to the object. For example, categories may be categorized by industry such as restaurants, pubs, and lodgings. Alternatively, categories may be classified according to a method of providing an object corresponding to the content.

In other words, the content can be categorized into different categories for when the user needs to visit the provider directly to receive the object corresponding to the content, when the provider delivers the object directly, and when the provider delivers the object through the courier. Can be distinguished.

In addition, the content selection unit 23 may select content of another category according to the time zone in which the content is provided. For example, the content selector 23 may select content of a restaurant category for lunch when the content providing time is 12:00, which is a lunch break. In addition, when the content providing time is 18:00, which is the dinner time, the content selection unit 23 may select the content of the tavern category for the dinner. In addition, the content selection unit 23 may select a content of a catering category, including a restaurant capable of delivering food, when the content providing time is from 0 to 24 hours on weekends.

For example, the content selection unit 23 sets the predetermined distance to 500m for the content of the category in which the user must visit the content provider directly, and sets the predetermined distance to 3km for the category in which the content provider directly delivers the object. The provider may set a predetermined distance to 10 km for content of a category for delivering an object.

In addition, the content selection unit 23 may select content of another category according to the weather for providing the content. For example, if the content selector 23 selects content belonging to a restaurant category at the current location of the user terminal, the content selector 23 corresponds to cool foods such as cold noodles and red bean shaved ice, assuming that the weather is hot. In the case of cold weather, the user may select content corresponding to hot food such as Seolleongtang and udon.

Content providing server 20 according to an embodiment of the present invention may include a content providing unit (24).

The content provider 24 may transmit the content selected by the content selector 23 to the user terminal 10. In this case, the extracted content may be composed of independent content layers. In this case, the content may include at least one of image data, text data, and video data.

Such content may be composed of one content that is arranged by sequentially arranging a plurality of sub-contents having a predetermined layer or display order displayed in a floating manner on a screen currently displayed on the user terminal 10.

Therefore, the calculation target specific system 100 according to an embodiment of the present invention may limit the location range to which the user belongs, and provide the filtered content to the user by filtering the content step by step based on the user. That is, the calculation target specific system 100 may limit the location range of the user and limit the number of target contents, thereby minimizing the amount of computation by reducing the number of (operation) target contents.

4 is a flowchart illustrating a method of defining a location of a user terminal and providing content adjacent to the limited user terminal to the user terminal according to a method for calculating a target according to an embodiment of the present invention.

First, the content providing server 20 obtains the user's location information from the user terminal 10 (S11). At this time, the content providing server 20 in step S11 of the GPS information of the user terminal 10, the identification ID information of the network equipment retrieved from the user terminal 10, the mobile IP (Internet Protocol) address information of the user terminal 10 Location information may be obtained using at least one piece of information. As another method of obtaining location information of the user terminal 10, the content providing server 20 may obtain analysis location information calculated based on past location information of the user corresponding to the user terminal 10.

In addition, in step S11, the content providing server 20 may obtain the location information of interest selected by the user corresponding to the user terminal 10.

Thereafter, the content providing server 20 may limit the range in which the location of the user terminal 10 is included using the acquired location information of the user (S12). At this time, in step S12, based on the location information of the user terminal 10 obtained in step S11, geohash (Geohash: location code of latitude and longitude) information indicating the location of the user terminal is obtained to determine the range including the location of the user terminal. It can be limited. At this time, the geo-hash information means the information expressed by 32-digit latitude-longitude code by processing the latitude-longitude value of the corresponding position. In other words, the geo-hash information is expressed as geo-hash information corresponding to the position information of the user terminal 10 by converting the latitude-longitude value representing the position information of the user terminal 10 into a 32-digit latitude-long code.

In step S12, the content providing server 20 may extract the target content having a location adjacent to the range including the location of the limited user terminal 10 (S13).

More specifically, the content providing server 20 checks the geohash information corresponding to the position information of the user terminal 10 from the first digit to the predetermined N th digit to identify the cell to which the position of the user terminal 10 belongs. Can be. The content providing server 20 may extract the target content based on the location range of the user terminal 10 established as described above.

That is, step S13 may extract the content within a certain distance range as the target content based on the position of the user terminal 10.

With reference to the geohash information of the content within a certain distance range, the content having the geohash information belonging to the adjacent cell can be extracted as the target content.

If the target content is extracted in step S13, the content providing server 20 may select at least some of the extracted target content (S14). In this case, step S14 may calculate the distance between the user terminal 10 and the extracted target content, and select only the content whose calculated distance is within a predetermined range.

To this end, location information corresponding to the content may be stored in association with each content.

In addition, the distance between the user terminal 10 and the content calculated by the content providing server 20 in step S14 may be a distance of a straight line or the shortest path. For example, the content providing server 20 may be calculated by applying a weight to a feature such as a bridge, a tunnel, or the like, in a moving path of the content and the user terminal 10 to be farther than the actual distance.

In operation S14, the content providing server 20 may select content belonging to a category corresponding to the usage history information based on the usage history information of the user terminal 10, from the target content extracted in operation S13.

That is, the content providing server 20 collects the usage history information including at least one of information of applications installed in the user terminal 10, usage time information of each application, and connection count information of each application, and usage history information. Content belonging to a category corresponding to may be selected. For example, when a user uses a lot of applications related to shopping, the content selector 23 may select content belonging to a shopping mall category.

In relation to step S14, the content providing server 20 is environmental information including at least one of geographic information, current weather information, current time information corresponding to the current location of the user terminal 10 of the target content extracted in step S13 It may select content belonging to a category corresponding to and.

In addition, the content providing server 20 may set the predetermined distance short when the content density is high, and set the predetermined distance long when the content density is low.

The content providing server 20 may select content of another category according to the weather for providing the content.

Meanwhile, the content providing server 20 may transmit the content selected in step S14 to the user terminal 10 (S15).

Accordingly, the operation target specifying method illustrated in FIG. 4 primarily limits the location range of the user terminal 10 using the location information of the user terminal 10, and contents of a location corresponding to the limited user terminal 10. Secondarily by limiting the content of the location adjacent to and to provide the limited content to the user terminal (10).

FIG. 5 is a detailed flowchart illustrating a process of defining a location of a user terminal by using geohash information including the location of the user terminal according to a calculation target specifying method according to an exemplary embodiment of the present invention.

The content providing server 20 may acquire location information of the user terminal 10 and obtain geohash information indicating the location of the user terminal 10 based on the obtained location information of the user terminal 10 ( S21). The description of the geohash information has been described above and will be omitted.

In relation to the content providing server 20 may check the geo-hash information of the user terminal 10 from the first digit to the predetermined N-th digit to identify the cell to which the position of the user terminal 10 belongs (S22). This assumes that the content providing server 20 checks the geohash information indicating the location of the user terminal 10 from the first digit to the predetermined ninth digit, as shown in FIG. 3, from the first digit to the ninth digit. It can be seen that the location of the user indicated by the geohash information up to is located in the cell “E”.

If it is determined in step S22 that the user's position belongs to the cell "E", the content providing server 20 may limit the content belonging to the cell "E" to the target content. In addition, the content providing server 20 may check the limited number of target contents (S23).

At this time, if the target content defined in step S23 is not equal to the number between the predetermined minimum value and the maximum value in the content providing server 20, the target content can be defined once again. That is, it may be checked whether the number of target contents defined in step S23 satisfies the number between the predetermined minimum value and the maximum value.

The content providing server 20 may determine whether the limited number of target content exceeds the maximum value (S24). At this time, if the number of the target content limited in step S24 exceeds the maximum value, it is possible to check the number of target content by adding the first number of geo-hash information of the user terminal 10 one by one (S25).

For example, in step S22, if the content providing server 20 confirms the geohash information of the user terminal 10 from the first digit to the ninth digit, the content providing server 20 reads the geohash information from the first digit. The number of target content can be confirmed by additionally checking up to the tenth digit. In other words, the content providing server 20 may repeat the process of confirming the number of target contents until the number of target contents becomes less than or equal to a predetermined minimum value and a maximum value.

On the other hand, if the limited number of target content does not exceed the maximum value in step S24, it may be checked whether the number of target content is less than the minimum value (S26). In this case, when the number of target contents defined in step S24 is less than the minimum value, the number of target contents may be checked by excluding the first digit of the geohash information of the user terminal 10 one by one (S27).

For example, the content providing server 20 may check the number of target contents by reducing the geohash information of the user terminal 10 from the first digit to the eighth digit. In other words, the content providing server 20 may repeat the process of confirming the number of target contents until the number of target contents becomes more than a predetermined number.

As described above, the content providing server 20 additionally checks the geohash information of the user terminal 10 from the first digit to the tenth digit (S25), or the geohash information of the user terminal 10 from the first digit to the eighth digit.
