  By the way, there is an approach to increase the number of viewing of display information by changing the order and position of contents displayed on a screen such as display information obtained via a network or the like. In such an approach, it is conceivable to use the conventional technique described in Patent Document 1 above. For example, it is conceivable to rearrange frequently used items based on a click log for display information.

According to this configuration, the display position of the content can be made appropriate according to the connection with the display information to be generated and the connection with the display information other than the generation target.

  The content relates to the purchase of the product, the connection information acquisition unit also acquires purchase information indicating the degree of purchase of the product from the content, and the display information generation unit acquires the purchase information acquired by the connection information acquisition unit. The display position of each content in the display information may be determined based on the above.

  Hereinafter, embodiments of a display information generation system and a display information generation method according to the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 shows a display information server 10 which is a display information generation system according to this embodiment. The display information server 10 generates display information to be displayed on the information communication terminal 20 and transmits the display information to the information communication terminal 20. The display information includes a plurality of contents. Each of the plurality of contents is information displayed in the display information. Specifically, for example, the display information is information on a topic that the user is interested in, or information for selling a product, and each content corresponds to information on each of the above topics and products. To do. The display information corresponds to, for example, the top page of the portal site.

  The content is classified into one of a plurality of content categories. The content category is a content type, and is set in advance by the administrator of the display information server 10 according to the content content, for example. Specifically, the content category is, for example, music, travel, shopping, fashion, video, or book. The display position in the content display information is determined by the display information server 10 as described later.

  The information communication terminal 20 is a device that acquires display information from the display information server 10 and displays it. The information communication terminal 20 is used by a user. Specifically, the information communication terminal 20 corresponds to a mobile phone, a smartphone, a PC (personal computer), or the like. The information communication terminal 20 has a communication function such as mobile communication, and transmits / receives information to / from the display information server 10 by the communication function.

  The information communication terminal 20 makes a display information transmission request to the display information server 10 in response to an operation such as a click on the information communication terminal 20 by the user. When receiving the transmission request, the display information server 10 generates display information corresponding to the transmission request and transmits the display information to the information communication terminal 20. The information communication terminal 20 receives and displays the transmitted display information. The information communication terminal 20 is installed with a browser that is an application for displaying display information. The received display information is displayed by the browser. Thus, the information communication terminal 20 is connected to the display information.

  The information communication terminal 20 further connects to the display information corresponding to the content by selecting the content included in the display information. This content selection is performed by an operation such as a click on the information communication terminal 20 by the user. In this way, the information communication terminal 20 connects to the content. The information communication terminal 20 stores a history of connection to content (which displayed content was clicked by the user) as a click log. Details of the click log will be described later.

  The information communication terminal 20 transmits the stored click log to the display information server 10. This transmission may be performed in response to a request from the display information server 10, or may be performed spontaneously from the information communication terminal 20. The information communication terminal 20 stores a user ID that is information for specifying the user in advance, and transmits the user ID together with the transmission of the click log.

  Subsequently, functions of the display information server 10 according to the present embodiment will be described. As shown in FIG. 1, the display information server 10 includes a correlation information acquisition unit 11, a connection information acquisition unit 12, a display information generation unit 13, and an output unit 14. Further, the display information server 10 has a function of a normal server that provides display information in addition to the above functions.

  The correlation information acquisition unit 11 is a correlation information acquisition unit that acquires correlation information (correlation data) indicating a correlation related to connection between content categories. The correlation information is represented by a numerical value between two content categories as shown in FIG. The correlation related to the connection between the content categories indicates how similar the connection to the contents of the two content categories is. For example, it indicates how much a user connected to content in one content category is connected to content in the other content category. For example, in the example of FIG. 2A, the higher the numerical value, the higher the correlation.

  The correlation information is used for determining the display position of the content in the display information as will be described later. From this point of view, the correlation between the same content categories may not necessarily indicate the correlation in the above sense.

  In order to calculate correlation information, the correlation information acquisition unit 11 acquires the correlation information calculation information indicating the degree of connection to the content for each content category and using a plurality of the connections as one unit. Correlation information is calculated based on the information calculation information. Specifically, the correlation information acquisition unit 11 calculates correlation information as follows.

  First, the correlation information acquisition unit 11 acquires a connection log (use log) as correlation information calculation information. The connection log indicates a history of connection to display information. For example, the connection log is information shown in FIG. As shown in FIG. 3A, the connection log is associated with time, user ID, and connection destination. The time is the time connected to the display information. The user ID is information that identifies a user (information communication terminal 20) that has made a connection. The connection destination is information for specifying the connection destination of the connected display information. As the connection destination, any information for specifying information on a conventional network can be used.

  The display information related to the connection log is the display information to be generated by the display information server 10 and the display information connected from the content of the display information (display information linked to the content of the display information to be generated). Different display information may be used. That is, the display information related to the connection log may be external data. Further, the display information related to the connection log may include display information (display information linked to the content of the display information to be generated) connected from the content of the display information to be generated.

  The correlation information acquisition unit 11 acquires connection logs related to display information to be a plurality of connection destinations for a plurality of user IDs. For example, the correlation information acquisition unit 11 acquires the click log stored in the browser of each information communication terminal 20 as a connection log. Alternatively, the correlation information acquisition unit 11 is a display information server that provides display information related to the connection log, or a relay device (external proxy) that relays communication between each information communication terminal 20 and the display information server. May be obtained by receiving a connection log. The connection log is obtained with user permission. That is, the connection log is for the user (information communication terminal 20) for which permission has been obtained and the connection destination for which permission has been obtained from the user. Alternatively, the connection log for external data may relate only to the connection to external data provided by the provider providing the display information server 10. That is, the connection log may not include information related to connection to external data provided by a business other than the business providing the display information server 10.

  The correlation information acquisition unit 11 converts each connection log (corresponding to one line of data in FIG. 3A) into a content category according to a conversion rule (dictionary) stored in advance. For example, if the display information connection domain provides a general Internet shopping service, the conversion rule is converted to a shopping content category, and the display information connection domain is a fashion-related network. If a shopping service is provided, it is converted into a fashion content category. That is, the conversion rule is such that the connection destination of the display information is associated with the content category, and the correlation information acquisition unit 11 performs conversion with reference to the connection destination of the display information of each connection log. FIG. 3B shows the connection log after conversion.

  Subsequently, the correlation information acquisition unit 11 determines which content category is connected to each user ID based on the correspondence between the user ID and the content category indicated in the converted connection log (which content category each user has Information indicating whether the content has been clicked at least once) is generated (converted into the data format). An example of this information is shown in the table of FIG. In the table of FIG. 4, the numerical value 1 indicates that the user indicated by the corresponding user ID has connected to the content of the corresponding content category. The numerical value 0 indicates that the user indicated by the corresponding user ID is not connected to the content of the corresponding content category. For example, a user whose user ID is “1” is connected to content whose content category is music, and is not connected to content whose travel category is travel and shopping. In this way, the connection log is handled with the same user ID data including information indicating connection to a plurality of display information as one unit (in units of user IDs).

Subsequently, the correlation information acquisition unit 11 calculates the support level of each content category from the generated information by the following formula stored in advance.
Support level = (number of data whose content category is 1 (number of user IDs)) / total number of data (number of all user IDs)
For example, if the generated information is as shown in FIG. 4, the degree of support for music is 3/5 = 0.60.

Subsequently, the correlation information acquisition unit 11 calculates the reliability of each content category from the generated information by the following formula stored in advance. The following formula is for calculating the reliability (A → B) from the content category A to the content category B.
Reliability (A → B) = (number of data in which content category A and content category B are both 1 (number of user IDs)) / (number of data in which content category A is 1 (number of user IDs)) )
For example, when the content category A is music and the content category B is travel, the number of data in which both the content category A and the content category B are 1 is 1, and the number of data in which the content category A is 1. Is 3, so the reliability is 0.33.

Subsequently, the correlation information acquisition unit 11 calculates the lift value of each content category from the calculated support level and reliability using the following formula stored in advance. The following equation is for calculating the lift value (A → B) from the content category A to the content category B.
Lift value (A → B) = Reliability (A → B) / (Support level of content category B)
For example, when the content category A is music and the content category B is travel, the reliability (A → B) is 0.33 and the support level of the content category B is 0.40, so the lift value (A → B) Becomes 0.83.

  The correlation information acquisition unit 11 calculates a lift value for all content categories that are different from each other. The calculated lift value is used as a value indicating the correlation related to the connection between the content categories described above. Since lift values are calculated for all different content categories, correlation information excluding the same content categories is obtained as shown in FIG. The lift value may be calculated by an arbitrary method such as calculation based on a conventional association rule.

Subsequently, the correlation information acquisition unit 11 performs a preset operation on a value having the highest correlation among values indicating correlation between different content categories, thereby indicating a value indicating the correlation between the same content categories. Compute a heuristic value that is Specifically, the calculation is performed as follows. The correlation information acquisition unit 11 stores a discoverability parameter in advance. The discoverability parameter is a numerical value of 0 to 1, and is set in advance by the administrator of the display information server 10, for example. The correlation information acquisition unit 11 is a value indicating the correlation between the same content categories by the following formula stored in advance from the highest correlation among the values indicating the correlation between different content categories and the heuristic parameter. Calculate the discoverability value.
(Discovery value) = (Maximum lift value) x (Discovery parameter)
For example, as shown in FIG. 2B, when the maximum value of all lift values is 1.46 and the heuristic parameter is 0.7, the heuristic value is 1.02. Thereby, the correlation information which shows the correlation of all the content categories as shown to Fig.2 (a) is obtained.

  The correlation information shown in FIG. 2A calculated by the correlation information acquisition unit 11 is stored (stored) in the display information server 10 and is referenced by the display information generation unit 13. A series of processing for acquiring correlation information by the correlation information acquisition unit 11, that is, for calculating correlation information, is periodically performed at predetermined time intervals, for example. In the present embodiment, the correlation information acquisition unit 11 calculates the correlation information based on the connection log. However, the correlation information may be acquired from an external device without performing the calculation.

  The connection information acquisition unit 12 is connection information acquisition means for acquiring connection information indicating the degree of connection to content for each content category. The connection information acquisition unit 12 acquires connection information as follows. For example, the connection information acquisition unit 12 acquires the connection log acquired by the correlation information acquisition unit 11. The connection information acquisition unit 12 acquires a connection log for a user ID (information communication terminal 20) related to a user who is a transmission destination of display information from the display information server 10 (display information from the own device 10). The connection information acquisition unit 12 may acquire a connection log of only information related to connection to content from the display information of the display information server 10. That is, information related to connection to display information other than the content of the display information server 10 may not be acquired.

  For example, the connection information acquisition unit 12 acquires information illustrated in FIG. The information acquired as shown in FIG. 5A is information in which time and content category are associated, for example. The time is the time when connected to the content. The content category is a content category of connected content. The connection information acquisition unit 12 counts the number of connections (number of clicks) that is the number of data for each content category, and uses the counted number of connections for each content category as connection information.

The connection information acquisition unit 12 may perform a preset calculation on the number of connections and use the calculated value as connection information. For example, the logarithm of the number of connections (for example, a logarithm with a base of 10 or a natural logarithm) may be taken, or the number of connections may be multiplied by a previously stored coefficient. For example, log ₁₀ (number of connections) may be used as connection information.

  The connection information acquisition unit 12 outputs the acquired connection information to the display information generation unit 13. A series of processing of connection information acquisition, that is, calculation of connection information by the connection information acquisition unit 12 is, for example, connection to display information provided from the information communication terminal 20 by the display information server 10 (display on the display information server 10). This is performed when there is an information transmission request. Or the said process may be regularly performed for every preset time interval, for example.

  The display information generation unit 13 determines the display position of each content in the display information based on the correlation information acquired by the correlation information acquisition unit 11 and the connection information acquired by the connection information acquisition unit 12, and performs the display Display information generating means for generating information. The display information generation unit 13 calculates the score for each content category by weighting the degree of connection to the content for each content category indicated by the connection information with the correlation indicated by the correlation information, and based on the calculated score Thus, the display position of each content in the display information is determined. The display information generation unit 13 calculates a score for each content category as follows.

  The display information generation unit 13 selects one content category Ci from all content categories. Here, i is an index indicating a content category. For example, if all content categories are music, travel, shopping, and fashion, select music. The score Si of Ci is set to zero. Subsequently, the display information generation unit 13 selects one content category Cj from all content categories. Here, j is an index indicating the content category. For example, if all content categories are music, travel, shopping, and fashion, select music.

  Subsequently, the numerical value of Ci (the number of connections) in the connection information and the value Dij indicating the correlation between Ci and Cj in the correlation information are integrated to obtain an intermediate score Sij. The intermediate score Sij is added to the score Si of Ci. Subsequently, another content category Cj is selected, and an intermediate score is calculated in the same manner. When calculation is completed for all the content categories Cj, the intermediate score at that time becomes the score of the content category Ci. Subsequently, another content category Ci is selected, and the score is similarly calculated.

  The display information generation unit 13 arranges the content in the display information in the order of the content category having the highest score. For example, the display information is generated by arranging the contents in the content category having a higher score so as to be located at the top of the display information. Thereby, the higher the score, the more easily placed the user's eyes. The content arranged in the display information is stored in the display information server 10 in advance. Further, for each content arranged in the display information, a content category is set in advance by the administrator of the display information server 10 according to the content of the content.

  The process of generating display information by the display information generating unit 13 is performed when there is a request for display information from the information communication terminal 20 to the display information server 10. The connection information used when generating the display information is that of the user ID corresponding to the information communication terminal 20 that requested the display information. The display information generation unit 13 outputs the generated display information to the output unit 14.

  The output unit 14 is an output unit that outputs the display information generated by the display information generation unit 13. Specifically, the output unit 14 outputs the display information by transmitting it to the information communication terminal 20 that requested the display information. The above is the function of the display information server 10 according to the present embodiment.

  FIG. 6 shows a hardware configuration of the display information server 10 which is a display information generation system according to the present embodiment. As shown in FIG. 6, the display information server 10 includes a central processing unit (CPU) 101, a random access memory (RAM) 102 and a read only memory (ROM) 103, which are main storage devices, a communication module 104 for communication, and The computer is configured with hardware such as an auxiliary storage device 105 such as a hard disk. The functions of the display information server 10 described above are exhibited by the operation of these components by a program or the like. The above is the configuration of the display information server 10 according to the present embodiment.

  Subsequently, a display information generation method, which is a process executed by the display information server 10 according to the present embodiment (an operation method of the display information server 10), will be described with reference to flowcharts of FIGS. First, a process when generating correlation information will be described with reference to FIG. This process is performed by the correlation information acquisition unit 11.

  In this process, first, a connection log as shown in FIG. 3A is acquired (S01, correlation information acquisition step). Subsequently, each connection log is converted into a content category, and a converted connection log as shown in FIG. 3B is obtained. Further, information indicating which content category is connected to each user ID as shown in FIG. 4 is generated from the converted connection log (S02, correlation information acquisition step).

  Subsequently, the support level of each content category is calculated based on the information (S03, correlation information acquisition step). Moreover, the reliability of each content category is calculated (S04, correlation information acquisition step). Subsequently, lift values of different content categories are calculated from the calculated support level and reliability level (S05, correlation information acquisition step). Subsequently, a discoverability value between the same content categories is calculated from a maximum value among lift values indicating correlations between different content categories and a discoverability parameter (S06, correlation information acquisition step). The calculated lift values and discoverability values are stored in the display information server 10 as correlation information shown in FIG. 2A (S07). The above is the processing when generating correlation information.

  Next, a process for generating display information will be described using the flowchart of FIG. This process is started when a transmission request for display information is made from the information communication terminal 20 to the display information server 10. The display information server 10 receives the transmission request (S11). Subsequently, the connection information is acquired by the connection information acquisition unit 12 (S12, connection information acquisition step). This acquisition is performed, for example, by receiving a connection log (click log) from the information communication terminal 20. Further, when the connection information is acquired in advance and stored in the display information server 10 before this processing, the connection information may be acquired by reading the stored information. The acquired connection information is input from the connection information acquisition unit 12 to the display information generation unit 13. Subsequently, the display information generation unit 13 calculates a score for each content category from the connection information and the correlation information (S13, display information generation step).

  The score calculation will be described with reference to the flowchart of FIG. First, the correlation information acquired by the correlation information acquisition unit 11 and stored in the display information server 10 is read by the display information generation unit 13 (S131). First, one content category Ci is selected from all content categories. The score Si of Ci is set to zero (S132). Subsequently, one content category Cj is selected from all the content categories (S133).

  Subsequently, the numerical value of Ci (number of connections) in the connection information and the value Dij indicating the correlation between Ci and Cj in the correlation information are integrated, and an intermediate score Sij is calculated (S134). The calculated intermediate score Sij is added to the score Si of Ci (S135). Subsequently, another content category Cj is selected (S136). Similarly, an intermediate score is calculated and added to the score Si of Ci (S133 to S135). When the above calculation is completed for all content categories Cj (No in S133), the score Si at that time is set as the score of the content category Ci.

  Subsequently, another content category Ci is selected (S137), and the score Si of the other content category Ci is similarly calculated (S132 to S136). When the calculation of the score Si is completed for all the content categories Ci (No in S132), the score calculation process ends.

  Returning to FIG. 8, subsequently, the display information generation unit 13 determines the arrangement of the content based on the calculated score of the content category, and generates display information (S14, display information generation step). The generated display information is output from the display information generation unit 13 to the output unit 14. Subsequently, display information is transmitted by the output unit 14 to the information communication terminal 20 that has requested transmission of display information (S15, output step). In the information communication terminal 20, the display information is received and displayed.

  In the present embodiment, the display position of the content is determined based on the degree of connection to the content for each content category. Therefore, even when the history of connection to the display target content itself is not sufficient, the display position of the content can be made appropriate. In addition, since the display position of the content is determined based on the correlation related to the connection between the content categories, for example, the display position of the content that is considered to be potentially interested by the user can be made appropriate.

  Specifically, content that is highly correlated with well-connected content can be displayed at a higher level even when the target user is not connected to the content itself. Thus, according to the present embodiment, even if the history of the content itself is not sufficient, the display information including a plurality of contents can be easily used by the user. That is, display information can be personalized appropriately. In particular, even when the information communication terminal 20 for the user to refer to the display information is a portable terminal having a small screen such as a smartphone, the service can be effectively recommended.

  Further, as in this embodiment, the score may be calculated by weighting the connection information with the correlation information. According to this configuration, the display position of the content can be determined appropriately and reliably, and the present invention can be implemented appropriately and reliably.

  Moreover, it is good also as calculating correlation information based on a connection log like this embodiment. According to this configuration, it is possible to obtain appropriate correlation information based on connection to information according to the actual content category, and to appropriately implement the present invention.

  In addition, as described above, when calculating the score, operations such as taking the logarithm of the number of connections or multiplying parameters may be performed. According to this configuration, for example, the degree of connection can be made in accordance with the purpose of content rearrangement, and as a result, appropriate content rearrangement can be performed. Specifically, the degree of personalization can be adjusted by suppressing the influence of the number of connections (number of clicks).

  Further, as in the present embodiment, the correlation between the same content categories may be calculated from the maximum value among the lift values indicating the correlation between the different content categories and the discoverability parameter. According to this configuration, for example, the display position of content in a content category with many connections can be set according to the purpose of content rearrangement, and as a result, appropriate content rearrangement can be performed. .

  For example, when the heuristic parameter is set to a high value (for example, a value close to 1), the connection to the content in the content category is reflected in the score to the content category to a high degree. Accordingly, content categories that are already connected by many users (that is, content frequently used by users) are displayed at the top. In this case, the convenience for the user is considered to be high, but the discoverability of new content is poor.

  On the other hand, when the discoverability parameter is set to a low value (for example, a value close to 0), the connection to the content of the content category is not reflected in the score to the content category, and the content category is a high degree. It will be reflected in the score for another content category. Therefore, content categories that are already connected by many users (that is, content frequently used by users) are displayed at the lower level, and content that is highly correlated with content categories that are already connected by many users are higher. Will be displayed. In this case, the discoverability of new content for the user is enhanced.

  Further, as described above, the information communication terminal 20 is configured such that the display position of each content in the display information including a plurality of displayed contents is (a) correlation information indicating a correlation related to connection between content types, (b) The information communication terminal 20 acquires and displays the display information generated by being determined based on connection information indicating the degree of connection to content for each type from the display information server 10.

  Subsequently, a modification of the present embodiment will be described. In the embodiment described above, when calculating the score of the content category, the connection to the content included in the display information to be generated is not distinguished from the connection to the content of other display information. It is good also as calculating a score distinguishing them.

  In this case, the connection information acquisition unit 12 includes connection information (click log of the display information) related to the content included in the display information to be generated and connection information (external connection) related to the content included in the display information other than the generation target. Log data). This acquisition is performed from an arbitrary user (user ID) as well as the correlation information calculation information acquired by the correlation information acquisition unit 11 as well as the display information providing user. The connection information acquisition unit 12 outputs the acquired connection information to the display information generation unit 13.

  The display information generation unit 13 determines the display position of each content based on the connection information related to the content included in the display information to be generated and the connection information related to the content included in the display information other than the generation target. To do. Based on the information input from the connection information acquisition unit 12, the display information generation unit 13 calculates a potential value for each content category as follows.

  The display information generation unit 13 calculates the support level of each content category from the connection information related to the content included in the display information to be generated. Further, the display information generation unit 13 calculates the support level of each content category from the connection information related to the content included in the display information other than the generation target. The calculation method of the support level is the same as that by the correlation information acquisition unit 11 described above.

The display information generation unit 13 calculates the potential value of each content category from the calculated degrees of support using the following formula stored in advance.
(Potential value) = (support level of external connection log data) / (support level of click log of this display information)
For example, for the fashion content category, when the support level of the external connection log data is 0.70 and the support level of the click log of the display information is 0.30, the potential value is 2.3. When the support level of the external connection log data is lower than the support level of the click log of the display information, the potential value is 1.

  The display information generation unit 13 calculates a new score by multiplying the score by the potential value, and determines the display position of each content based on the new score.

  According to this configuration, the display position of the content can be made appropriate according to the connection with the display information to be generated and the connection with the display information other than the generation target.

  The support level of each content category calculated from the external data indicates how much content of each content category is browsed (market share) other than this site (display information provided by the display information server 10). Since the content category content that has just been introduced to this site has a small number of browsing, connection logs are not accumulated with the existing method. However, by using the market share of external sites, it is possible to set the order of contents in consideration of general market share even for sites that are not clicked so much.

  For example, it is assumed that the content category is fashion and the support level of a moving image is 0.9 and 0.2, respectively. Suppose that fashion content is newly introduced. If the number of connections for fashion content and video content is 1 and 10, respectively, a video with a large number of connections is set higher than fashion according to the conventional method. If the score is calculated by multiplying the degree of support, the fashion content can be set at the top. This enables rearrangement that reflects general user trends. Originally, the score is multiplied by the potential value, but for the sake of simplicity in the above example, the case where it is multiplied by the number of connections is described.

  Further, when the content is related to purchase of a product, the display position of each content may be determined based on whether or not the product is purchased through the content. The content related to the purchase of the product includes, for example, information on the product to be sold, and the user can purchase the product via the content by clicking a purchase button included in the content. .

  In this case, the connection information acquisition unit 12 also acquires purchase information (purchase log) indicating the degree of purchase of the product from the content. As shown in FIG. 5B, the purchase information is, for example, associated with time and content category. The time is the time when the product is purchased through the content. The content category is a content category of content for which a product is purchased. For example, the connection information acquisition unit 12 acquires the purchase information stored in the browser of each information communication terminal 20 by receiving the purchase information. The connection information acquisition unit 12 outputs the acquired purchase information to the display information generation unit 13.

The display information generation unit 13 determines the display position of each content in the display information based on the purchase information. Based on the information input from the connection information acquisition unit 12, the display information generation unit 13 calculates a conversion value for each content category as follows.
(Conversion value) = (Number of purchases) / (Number of connections)
For example, when the number of connections is 3 and the number of purchases is 1 for the book content category, the conversion value of the book content category is 0.33. The conversion value may be calculated from the number of purchases and the number of connections for each user ID (display information transmission target), or may be calculated from the total number of purchases and the number of connections of a plurality of user IDs. .

  The display information generation unit 13 calculates a new score by multiplying the score by the conversion value, and determines the display position of each content based on the new score.

  According to this configuration, the display position of the content can be made appropriate in accordance with the purchase of the product related to the content, for example, the purchase rate as described above. The above conversion value is the ratio of the number of purchasers in the content to the total number of people who clicked each content. The higher the conversion value, the higher the sales effect of the target site. By multiplying the number of connections by the conversion value, content with a high sales effect can be set at the top.

In addition, when using either a potential value or a conversion value, the display information generation part 13 may calculate the secondary score of each content category as follows, and may determine the display position of each content.
(Secondary score) = (primary score of content category) × α × (any of potential value and conversion value of content category) × β
The primary score of the content category is a score calculated in the above-described embodiment. Α and β are parameters set in advance. For example, for a fashion content category, when the primary score is 2.3, α is 0.5, and β is 0.7, the secondary score is 2.76. In addition to the above formula, it is also possible to suppress the influence of the potential value by taking the logarithm of the potential value (for example, the logarithm with the base 10 or the natural logarithm) and multiplying by the coefficient β. is there.
