  The service information acquisition unit 18 transmits the query input from the query acquisition unit 12 to the service information provision server that provides the service specified by the query classification unit 14 among the service information provision servers 9-1 to N. Get service information associated with this query.

  The posting determination unit 20 refers to the click log storage unit 36 and determines whether service information can be posted on the search result page. When the non-posting period is not set for the content corresponding to the second reference information included in the service information, the placement determination unit 20 determines that the content can be posted. On the other hand, when the non-posting period is set for the content corresponding to the second reference information included in the service information, the placement determination unit 20 determines that the content cannot be posted.

  The position determination unit 22 refers to the click log storage unit 36 and determines the posting position of the search result information and the service information on the search result page. The position determination unit 22 includes statistical information (for example, click rate) (access information) and arrangement order regarding selection of first reference information (first content) included in the search result information, and second reference information included in the service information. Based on statistical information (for example, click rate) (access information) regarding the selection of (second content) (based on the magnitude relationship between the click rate of the first reference information and the click rate of the second reference information), The relative placement position of the second reference information with respect to the first reference information arranged in the order of

  Here, “click rate” is defined. “Click rate” means CTR (Click Through Rate), which is a value obtained by dividing the number of accesses to each content (number of clicks) by the number of times each content has been recommended (number of impressions, number of display). “Click rate” is an example of “responsiveness to content”. Note that “click” in the present application is not limited to an operation of pressing and releasing a button such as a mouse, but includes a tap on a touch panel type input device.

  The generation unit 24 uses the search result information acquired by the search result acquisition unit 16 and the service information acquired by the service information acquisition unit 18, and uses the search result based on the posting position determined by the position determination unit 22. Generate a page. The generation unit 24 transmits the generated search result page to the terminal device 3 via the communication unit 10.

  The batch processing unit 26 uses the access log stored in the access log storage unit 32 to perform various counting processes such as counting the number of accesses, the number of clicks, and the click rate. The batch processing unit 26 executes the aggregation process at a predetermined timing such as every day, every week, or every month.

  The non-publication processing unit 28 determines content to be non-publication based on the access information of content corresponding to the second reference information included in the service information. Further, the non-posting processing unit 28 determines the non-posting period of the content determined based on the access information of the content corresponding to the second reference information included in the service information and the reliability information of the service providing the content. Set.

  The access log storage unit 32 stores an access log of access from the terminal device 3. The query classification storage unit 34 stores a correspondence relationship between a query and a service (number of accesses for each service) selected from the search results. The click log storage unit 36 stores search result information data, service information data, and the like. The content posting status storage unit 38 stores the number of contents that can be posted for each service and the number of contents that are not posted.

(Search result page generation process)
Next, processing of the search server 5 will be described with reference to the drawings. FIG. 3 is a flowchart showing an example of the flow of search result page generation processing by the search server 5.

  First, the query acquisition part 12 acquires the query contained in the access from the terminal device 3 via the communication part 10 (step S101). The query acquisition unit 12 stores the access log in the access log storage unit 32.

  Next, the query classification unit 14 specifies a service corresponding to the query input from the query acquisition unit 12 with reference to the query classification storage unit 34 (step S103).

  FIG. 4 is a diagram illustrating an example of the query classification data D1 stored in the query classification storage unit 34. As illustrated in FIG. As illustrated in FIG. 4, the query classification storage unit 34 stores data of items of “query”, “service”, “number of accesses”, and “ratio”. For example, for data whose query is “AAA”, “service 1”, “service 2”, “service 3”, and the like are stored as corresponding services. Further, regarding the data whose query is “AAA”, the access number of the service “service 1” is “2532”, and the ratio of the access number is the access of the entire service provided in association with the query “AAA”. Data that is “52%” of the number is stored. In addition, regarding the data whose query is “AAA”, the number of accesses of “service 2” is “0” and the rate is “0%”, the number of accesses of “service 3” is “1023” and the rate is “21”. Data such as “%” is stored. Here, for example, the query classification unit 14 selects one or more services having a ratio equal to or higher than a predetermined threshold as the corresponding service. For example, when the threshold is set to “20” and the acquired query is “AAA”, the query classification unit 14 sets “Service 1” and “Service 3” as corresponding services. As specified. Note that. The query classification unit 14 may specify the service having the highest ratio among the services associated with the specific query as the corresponding service without using the threshold value.

  Next, the search result acquisition unit 16 transmits the query input from the query acquisition unit 12 to the search result providing server 7 and acquires search result information from the search result providing server 7 (step S105).

  Next, of the service information providing servers 9-1 to N, the service information acquiring unit 18 obtains service information associated with the query from the service information providing server that provides the service specified by the query classification unit 14. Obtain (step S107).

  Next, the posting determination unit 20 refers to the service information data D3 stored in the click log storage unit 36 and corresponds to the second reference information included in the service information acquired from N from the service information providing server 9-1. It is determined whether or not content can be placed (step S109). The posting determination unit 20 determines that the content can be posted when the “non-publishing period” is not set in the content (for example, when the value of the “non-posting period” is “0”). . On the other hand, when the “non-publishing period” is set in the above content (for example, when the value of “non-publishing period” is set to “90” or the like), It is determined that this content cannot be posted.

  Next, the position determination unit 22 determines the posting position of the first reference information included in the search result information and the second reference information included in the service information determined to be able to be posted by the posting determination unit 20 (step) S111). Based on the click rate of the first reference information included in the search result information and the click rate of the second reference information included in the service information, the position determination unit 22 positions the first reference information and the second reference information. To decide. A method for determining the posting position by the position determination unit 22 will be described later.

  Next, the generation unit 24 uses the search result information acquired by the search result acquisition unit 16 and the service information acquired by the service information acquisition unit 18 based on the posting position determined by the position determination unit 22. A search result page is generated (step S113).

[Positioning method without sorting search result information]
FIG. 5 is a diagram illustrating an example of the search result information data D2 stored in the click log storage unit 36. As illustrated in FIG. FIG. 6 is a diagram illustrating an example of the service information data D3 stored in the click log storage unit 36. As illustrated in FIG.

  A position determination method when the search result information including the first reference information provided from the search result providing server 7 and arranged according to a predetermined rule is not rearranged will be described. The position determination unit 22 determines a position at which the second reference information included in the service information is inserted into the search result information including the first reference information arranged according to a predetermined rule. For example, among the first reference information arranged according to a predetermined rule, the position determination unit 22 calculates a click rate of the first reference information arranged first and a click rate of the second reference information to be inserted. Compare. Here, when the position determination unit 22 determines that the click rate of the second reference information is larger than the click rate of the first reference information arranged first, the position determination unit 22 determines the placement position of the second reference information. 1 Determined above the reference information. On the other hand, when the position determination unit 22 determines that the click rate of the second reference information is less than or equal to the click rate of the first reference information arranged first, the position determination unit 22 clicks the second reference information arranged second. The rate and the click rate of the second reference information are compared. Thereafter, the same process is repeated to determine the position of the second reference information.

  FIG. 7 is a diagram showing a search result page P1 generated based on the posting position determined according to the position determination method described above. As shown in FIG. 7, “search result 1 (URL 4)”, “search result 2 (URL 2)”, “search result 3 (URL 1)”, “search result 4 (URL 3) provided from the search result providing server 7 The second reference information in which “service” is “service 1” and “content” is “content 1-1” is inserted into the search result information including the first reference information arranged in the order of “ In this case, the click rate “5.26” of the second reference information is smaller than the click rates of “search result 1 (URL 4)” and “search result 2 (URL 2)”, and “search result 3 (URL 1)”. Greater than clickthrough rate. For this reason, the position determination unit 22 sets the posting position of the second reference information at a higher rank than “search result 3 (URL 1)” (between “search result 2 (URL 2)” and “search result 3 (URL 1)”). To decide. The number of contents displayed on the search result page P1 is arbitrary.

[Position Determination Method for Sorting First Reference Information]
Next, a position determination method for rearranging the search result information will be described. The position determination unit 22 arranges the first reference information included in the search result information and the second reference information included in the service information in descending order of the click rate (so that the click rate is in descending order), and the posting position. decide.

  FIG. 8 is a diagram showing a search result page P2 generated according to the posting position determined according to the position determination method described above. As shown in FIG. 8, the first reference information (“URL1”, “URL2”, “URL3”, “URL4”) included in the search result information, “Service” is “Service1”, and “ When rearranging with the second reference information whose “content” is “content 1-2”, the position determination unit 22 performs “search result 1 (URL 2)”, “search result 2 ( URL 4) ”,“ search result 3 (URL 1) ”,“ service 1 (content 1-2) ”, and“ search result 4 (URL 3) ”are determined in this order.

  Note that the position determination unit 22 determines that the “reset flag” is set in the content corresponding to the second reference information included in the service information (for example, when the reset flag is set to “1”). The placement position of the content for which the reset flag is set may be determined as a predetermined initial position. This “reset flag” indicates content for which the non-posting period has elapsed. Note that the search server 5 may determine the position of the content for which the reset flag is set, not the predetermined initial position, but the position corresponding to the past click rate performance value.

(Non-publication period setting process)
Next, non-posting period setting processing will be described with reference to the drawings. FIG. 9 is a flowchart illustrating an example of the flow of the non-posting period setting process performed by the search server 5. The setting process of the non-publication period is performed at a predetermined timing such as daily, weekly, monthly, or the like.

  First, the batch processing unit 26 acquires an access log from the access log storage unit 32, and based on the data included in the access log, the “access count” and “ratio” data stored in the query classification storage unit 34. Is updated (step S201).

  Next, based on the data included in the access log described above, the batch processing unit 26 displays the “display count”, “click count”, and “click rate” of the search result information data D2 stored in the click log storage unit 36. ”Is updated, and the“ display count ”,“ click count ”, and“ click rate ”data of the service information data D3 are updated (step S203).

  Next, the non-posting processing unit 28 determines the content to be non-posted based on the click rate of each content in the updated service information data D3 (step S205). For example, the non-publishing processing unit 28 reads one data associated with a certain query from the service information data D3 in the click log storage unit 36, and the click rate of this data and the search result information data D2 associated with the same query. Are compared with the lowest click rate of the first reference information. If the click rate of the content of the service information data D3 is equal to or higher than the minimum value of the click rate of the first reference information of the search result information data D2, the non-publishing processing unit 28 does not determine that the content is not posted. On the other hand, when the click rate of the content of the service information data D3 is less than the minimum value of the click rate of the first reference information of the search result information data D2, the non-publishing processing unit 28 determines that the content is not posted. . Note that the non-posting processing unit 28 may determine that this content is non-posting when the click rate of the content of the service information data D3 is equal to or less than a predetermined threshold.

  Next, the non-posting processing unit 28 calculates a non-posting period for the content determined to be non-posting according to the following procedure (step S207).

  The non-posting processing unit 28 calculates the non-posting period of each content based on the reliability information of each service and the actual value of the click rate of each content. The non-publishing processing unit 28 includes statistical information (for example, click rate) regarding the selected content selection, and statistical information (for example, a content for which a non-posting period has been set among a plurality of contents provided by the service providing the content) And the number of contents for which a non-posting period has been set). The non-posting processing unit 28 calculates the non-posting period of each content based on, for example, the following formula (1).

  In the above formula (1), Max_HideDays (q, m) indicates a non-posting period, BaseDays indicates an upper limit value of the non-posting period, and S_BadScore (m) indicates a penalty term for the service. Q_BadScore (q, m) indicates a penalty term of the content. Also, q and m indicate queries and services. Α indicates a weighting factor of the penalty term of the content.

  As shown in Expression (1), the non-publishing period (Max_HideDays (q, m)) is determined by the query and the service. The upper limit value (BaseDays) of the non-posting period is set in advance as a predetermined value such as 90 days, for example.

  The weighting coefficient (α) is defined by the following equation (2), for example.

  In the above formula (2), a is a parameter for adjusting the sharpness of the sigmoid curve, and b is a bias term. By setting a and b, the value of the weighting factor α can be adjusted. imps_span is the total number of display times (number of impressions) in the past predetermined period. The click rate is a value obtained by dividing the number of clicks by the number of times of display. The greater the number of times of display, the higher the reliability of the click rate. Further, by using the sigmoid curve, when the number of times of display is small, the weight coefficient α becomes small, and the weight of the penalty term of the service becomes large. On the other hand, when the number of times of display is large, the weighting factor α increases, and the weight of the penalty term of the content increases. That is, the non-posting processing unit 28 performs weighting so that the degree of influence of the content access information on the non-posting period becomes larger than the service reliability information as the number of times the content is posted.

  The penalty term for service (S_BadScore (m)) is defined by the following equation (3), for example.

In the above formula (3), Q_num _hide (m) indicates the number of non-published contents in each service, and Q_num _show (m) indicates the number of posted contents in each service. The non-posting processing unit 28 stores the number of these non-posting contents (Q_num _hide (m)) and the number of the posting contents (Q_num _show (m)) in the content posting state storage unit 38 as shown in FIG. Obtained from the stored content publication status data D4. The higher the percentage of unpublished content, the worse the quality of content provided by this service. The service penalty term (S_BadScore (m)) may be based on the average value of the click rate of the content in each service. In addition, the penalty term (S_BadScore (m)) of the service may be based on a “non-publishing ratio” obtained by dividing the number of non-publishing contents in each service by the number of postings.

  The content penalty term (Q_BadScore (q, m)) is defined by the following equation (4), for example.

  In the above formula (4), Avg_CTR (search_results) is included in the search result information positioned lower than the posting position of each content displayed together with each content on the last posting date before the aggregation processing, for example. The average click rate of the first reference information. Further, Avg_CTR (viewable (q, m)) indicates an average click rate when each content is posted at a visually recognizable position in a predetermined period in the past. The visually recognizable position indicates, for example, a position that is displayed without performing a scroll process or the like when the search result page is displayed on the display device.

  By using such a content penalty term (Q_BadScore (q, m)), even if a non-posting period is set for content that usually has a high click rate for some reason, the non-posting The period will be short and will be republished at a relatively early stage. If the posting process starts again after the non-display period has passed, the average click-through rate at the viewable position will gradually decrease and the non-display period will increase accordingly if the actual CTR is low. .

  Note that the non-posting processing unit 28 performs a non-posting period update process for content for which a non-posting period has already been set during the non-posting period calculation process. For example, when the non-publication processing unit 28 performs a non-publication period calculation process every day, a process of subtracting “one day” from the set non-publication period is performed. When the non-publication period ends (when the non-publication period becomes “0” as a result of the subtraction process), the non-publication processing unit 28 sets a reset flag in the corresponding content data of the service information data D3. (For example, the reset flag is set to “1”).

  Note that the non-posting processing unit 28 releases the reset flag (for example, sets the reset flag to “0”) for the content for which the reset flag is set during the aggregation process.

  Further, when the reliability information of each service changes, the non-publication period may be increased or decreased according to the result. It is possible to detect the improvement in the reliability information of the service in order to perform the reset quickly, and to shorten the non-posting period of the content that has already been hidden.

  According to the information processing apparatus of the embodiment described above, it is possible to provide appropriate information according to the user's intention in an effective format. Content corresponding to the second reference information based on the access information of the content corresponding to the first reference information included in the search result information and the access information of the content corresponding to the second reference information included in the service information By determining the posting position, it is possible to arrange information according to the user's intention at a position that is easily noticeable by the user. Further, by setting the non-posting period of this content based on the access information of the content corresponding to the second reference information and the reliability information of the service providing the content corresponding to the second reference information, It is possible to prevent the provision of information that is less relevant to the intention of the user.

  In the above embodiment, as shown in the search result information data D2 shown in FIG. 5, using the “display count”, “click count”, and “click rate” counted for each URL, the position determination process and An example of performing the non-posting period setting process has been described. However, “display count”, “click count”, and “click rate” aggregated for each display position of the search result in the search result page may be used. For example, using the “display count”, “click count”, and “click rate” aggregated in units such as the search result arranged first in the search result page, the search result arranged second, etc. Good.

  In the above embodiment, the example in which the position determination process and the non-posting period setting process are mainly performed using the “click rate” has been described. However, it is not limited to the click rate, but may be, for example, simply the number of accesses to the linked page, or a CVR (Conversion Rate) obtained by dividing the number of conversions on the linked page by the number of accesses to the linked page. ).
