Description

The present invention relates to an information processing device, a terminal device, an information processing method, a display method, an information processing program, and a display program that perform information processing related to a display order determination method for an item set that satisfies a specific condition.

In recent years, with the advancement of digital technology and network technology, items such as digital contents and articles are distributed and sold using a network. Opportunities to collect information through search sites are also increasing. Along with this, there is an increasing need for a technology that selects and provides information on items that are likely to be of interest to the user from among a large number of items and information that matches the purpose.

For example, there is a recommendation process using collaborative filtering as one of the techniques for recommending items. In recommendation processing using collaborative filtering, a large number of usage histories are accumulated, and items that match the user's preference are recommended using the usage histories.
In addition, in order to maintain the interest in the user's recommendation, a technology for changing a set of items presented to the user has been developed.
For example, Patent Literature 1 and Patent Literature 2 disclose a technique that preferentially recommends an unpresented item using a user's item access history and presentation status.

JP 2009-157500 A JP2008-146147

Patent Document 1 refers to a user's access history, excludes items that have been presented from items to be recommended, and recommends only items that have not been presented. Therefore, all related items can always be replaced.
Patent Document 2 discloses the number of times an item is presented by using a distribution counting sort for items that are sorted in advance according to an index such as popularity order or price order using the item presentation status for a keyword input by a user. By sorting in ascending order, it is difficult to present the previously presented item when another keyword is input, so the presented item can be changed.

However, in the above-mentioned Patent Document 1, every time a related item is browsed, all related items are exchanged. Therefore, the user says, “This recommendation changes every time. I felt "I don't know," and sometimes I couldn't get the user's confidence in related items.

Further, in Patent Document 2, since the number of items presented is counted for each user without distinguishing keywords, even a keyword that is input for the first time by a certain user may be an item that is highly relevant to the keyword. If the keyword is presented many times for other keywords entered by the user, the display order will drop, so while the user is using it many times, In some cases, the user's reliability cannot be obtained for the presentation of the item set for the keyword. Further, Patent Literature 2 discloses a service that presents an item related to an item that has been viewed / used as an item that has been viewed / used as a keyword, an item set for the keyword as an item set that is related to an item that has been viewed / used
Although this method can be used, there is a similar problem.

Therefore, the present invention provides an item related to a key condition such as a keyword or an item such as an item set related to a keyword or an item set related to an item browsed / used by a user. An object of the present invention is to promote the use of a user's service by presenting an item so as to achieve both ensuring of reliability and maintaining interest when presenting a set.

The detailed display information included in the display information in the first storage format of the display information and the combination of the item identifier and the final display order included in the display information in the second storage format of the display information are the browsing specifying information in this embodiment. Thus, the display information storage unit 135 becomes the browsing information storage unit in the present embodiment.

If the display history includes other information such as page information that is information related to the page on which the item is displayed, the display information may be created in association with the information. Of the page information, information related to the page on which the related item is displayed is referred to as related item display page information. In addition, in the display information related to the related item detailed information, if a set identifier for specifying a set of related item information that is the basis for creating the related item detailed information can be acquired, the display information may be generated in association with the set identifier. .

The display total information storage unit 136 stores a plurality of display total information. FIG. 9 is a diagram illustrating a storage state of the display total information storage unit 136. Display aggregate information is a user identifier (user_i
d), key condition (key), item identifier (item_id), and browsing rate total value (
view_total) and final display time information (last_disp_date) are associated with each other and stored in a table format as shown in FIG. The browsing rate total value is a value obtained by totaling the browsing rates to be described later, and the larger the number of items displayed as item detailed information on the terminal display unit 34 of the terminal device 3, the larger the value. Therefore, the larger the browsing rate total value, the higher the possibility that the user corresponding to the user identifier is browsing the item many times. The last display time information is time information when the item corresponding to the item identifier included in the display total information is last displayed on the terminal display unit 34 of the terminal device 3. Note that the combination of (user_id, key, item_id) is unique and does not allow duplication. The final display time information is the transmission time information in the present embodiment.

The information processing server control unit 11 performs overall control on each unit configuring the information processing server device 1. The information processing server control unit 11 includes a usage history registration unit 111, a display information registration unit 112, a related item selection unit 113, a display information aggregation unit 114, and a display order determination unit 11.
And 5.
The usage history registration unit 111 receives the usage history from the terminal device 3 via the network 2, and stores the received usage history in the usage history storage unit 133.
The display information registration unit 112 performs display information registration processing. In the display information registration process, display information is created in accordance with the storage format of display information based on the display history received from the terminal device 3 via the network 2, and the created display information is stored in the display information storage unit 135. Is stored.

The related item selection unit 113 performs related item selection processing for key conditions for selecting related items.
In the related item selection process, first, the degree of association between the key condition to be selected and each item is calculated. Next, a plurality of related items are selected based on the calculated relevance level. Next, for each selected related item, related item information that associates at least the key condition to be selected, the item identifier of the selected related item, and the degree of relevance is created. And all the created related item information is memorize | stored in the related item information storage part 134. FIG. A method for calculating the degree of association between the key condition to be selected and each item and selecting a plurality of related items based on the calculated degree of association is referred to as a related item selection method. A set of items for which the degree of association is calculated is a related item candidate set.

In the related item selection process, multiple related item selection methods are prepared. By selecting related items for each related item selection method for the selection target key conditions, one selection target key condition can be selected. A plurality of sets of related item information can be created. At this time, in order to distinguish the set of selected related item information for each related item selection method,
The related item information storage unit 134 needs to use the second storage format. Then, after associating individual set identifiers for each related item selection method in advance, a key condition to be selected, a set identifier associated with the related item selection method, an item identifier of the related item,
What is necessary is just to store the related item information which linked | related the relevance degree in the related item information storage part 134. FIG.

The related item selection process may be performed every time a related item acquisition request is received from the terminal device 3. In addition, for each predetermined timing predetermined by the service provider,
A key condition that satisfies a predetermined condition may be extracted, and a related item selection process may be performed for each extracted key condition. As the predetermined timing, a predetermined time interval (for example, every 24 hours) may be used, or a usage history may be received a certain number of times. Also, the time interval may vary from Monday to Friday every 3 hours, Saturday every 6 hours, and Sunday every 12 hours. Also, the time interval may be changed according to the season, such as shortening the time interval in summer and increasing the time interval in winter. The key condition satisfying the predetermined condition may be an item identifier of an item browsed / used within a predetermined period such as one month retroactively from the present, or a related condition viewed by the user within the predetermined period. It may be an item identifier that is a key condition corresponding to an item, or may be an item identifier of an item used by a predetermined number (for example, five) or more users. Of course, all item identifiers that are key conditions may be used.

Here, an example of a related item selection method will be described.
Using the usage history stored in the usage history storage unit 133, the related item of the item corresponding to the key condition to be selected is selected. To select related items, for example, Jac
There is a method of calculating a relevance level using a card coefficient and selecting a related item using the calculated relevance level. Specifically, U (ib) is a set of users using the item ib which is a key condition to be selected, U (is) is a set of users using another item is, and U (
The number of users existing in both ib) and U (is) is | U (ib) ∩U (is) |
The number of users existing in at least one of ib) and U (is) is expressed as | U (ib) ∪U (
is) |, and the relevance v (ib, is) is calculated using equation (1).

Then, a predetermined number of items or items whose calculated relevance is higher than a predetermined value are selected as related items in descending order of calculated relevance. Of course, all items for which the degree of relevance is calculated may be selected as related items. For example, there is almost no relevance to the key condition to be selected, such as the lowest value of the degree of relevance. Items should be excluded. In this way, by selecting related items based on the degree of relevance, only items that are highly relevant to the key condition can be set as related items. In addition, if the preference degree which shows the user's preference degree with respect to an item is calculated, a cosine distance, a Pearson product-moment correlation coefficient, etc. can be used for a relevance calculation.
The above is an example of the related item selection method. Of course, using a method other than the method described above, the degree of association between the key condition to be selected and the item may be calculated, and the related item may be selected.
What is necessary is just to select a related item by the method suitable for a service. Specifically, for example, in the case of a service such as a search site, the degree of association between a keyword that is a key condition and a web page that is an item may be calculated using tf-idf that is a known technique.

When the newly created related item information is stored in the related item information storage unit 134, if the related item information created before the selection target key condition already exists, the previously created related item information is stored. After deleting all item information, the newly created related item information may be stored. In addition, a section for storing previously created related item information may be prepared in the information processing server storage unit 13 to hold previously created related item information.
In addition, the related item selection part 113 in this embodiment has a role of a related degree calculation part.
The display information totaling unit 114 performs display information totaling processing.
The display information aggregation process may be performed every time display information is stored in the display information storage unit 135. Further, similarly to the related item selection process, it may be performed at predetermined timings predetermined on the service providing side.
Two types of display information aggregation processing procedures will be described below.
First, the first display information aggregation process will be described with reference to FIG. The first display information tabulation process updates the display tabulation information using only newly registered display information, in other words, display information that has not been used in the previous processing.

First, the display information totaling unit 114 acquires all unprocessed display information from the display information storage unit 135 (step S101). In order to determine unprocessed display information, a process determination flag indicating whether the display information has been processed or not processed is added to the display information, and the determination may be made based on the flag. In this case, when registering in the display information storage unit 135, the display information processing determination flag is left unprocessed, and when it is acquired in this step, the display information processing determination stored in the display information storage unit 135 is determined. The flag may be updated from unprocessed to already processed. Further, the latest acquisition time information indicating the time when the previous process was performed may be stored in the information processing server storage unit 13 and only display information registered after the latest acquisition time information may be acquired as unprocessed display information. Good. In this case, after acquiring all unprocessed display information, the latest acquisition time information may be updated. When page information is included in the display information, it can be acquired only for unprocessed display information having page information that satisfies a predetermined condition. Specifically, for example, the processing may be performed by limiting the page information to display information that is related item display page information. By limiting the display information to the display information corresponding to the related item display page information, only the browsing status of the related items can be aggregated by performing the processing described later.

Next, the display information totaling unit 114 selects one of the display information acquired in step S101, for example, in the order of acquisition (step S102).
Next, the display information totaling unit 114 calculates a viewing rate for each item identifier included in the display information selected in step S102 (step S103). Display information storage unit 1
When the storage format of 35 is the first storage format, one or more item identifiers are included in the display detailed information of the display information, so it is necessary to calculate a viewing rate for each item identifier. The browsing rate is a value that increases as the possibility that the user has browsed the item increases, and the property of the browsing rate also changes depending on the calculation method of the browsing rate.

Below, the calculation method of a browsing rate is demonstrated.
The first method of calculating the browsing rate is a method of uniformly assigning the same value (for example, “1”) regardless of any key condition and any item identifier. This method assumes that all displayed items are viewed by the user regardless of the key conditions.
At this time, the browsing rate total value that is a value obtained by totaling the browsing rate is displayed on the terminal display unit 34 of the terminal device 3.
Only proportional to the number of times that item is displayed.

The second method for calculating the viewing rate is a method for calculating the browsing rate so that the higher the final display rank, the higher the value. Specifically, for example, when the final display order for the item i in the key condition k of the user u is rank (u, k, i), the viewing rate vr (u, k, i) is
Using the constant α1 (> 0), the constant α2 (> 0), and the constant β1 (> = 0), it can be calculated by the equation (2). Further, the ceiling function ceil, an integer N of 2 or more, a constant α3 (> 0), a constant α4 (> 0), and a constant β2 (
> = 0) and can also be calculated by equation (3).

Moreover, as long as it decreases monotonously as in equation (4), the viewing rate calculation formula may be changed according to the final display order.

As described above, any function that monotonously decreases with respect to the final display order may be used. Further, as shown in FIG. 11, for each key condition, a correspondence table in which a numerical value that monotonously decreases according to the final display order is associated with the final display order as a viewing rate is stored in the information processing server storage unit 13 in advance. In addition, the browsing rate may be acquired from the correspondence table. The second method of calculating the browsing rate is a method that is more suitable when an item having a higher final display order is displayed at the top of the page displaying the item detail information. This is a method of calculating the viewing rate based on the assumption that the user is viewing the item displayed at the top of the page firmly, but the item at the bottom of the page is hardly viewed It is. At this time, the browsing rate total value tends to be larger as the number of times the item is displayed on the upper part of the page related to the item detailed information being displayed on the terminal display unit 34 of the terminal device 3 increases.

In addition, when page information is included in display information, the calculation method of the browsing rate to be used may be changed for each page information. For example, as shown in FIG. 12 (FIGS. 12A to 12C), three related item display pages are prepared for one service, and the related item display page information is p1 as shown in FIG. Only three related items are displayed on the related item display page corresponding to a), and 20 related items are displayed on the related item display page corresponding to FIG. Are displayed side by side, and the related item display page information corresponding to FIG.
Assume that 10 rows of related items arranged side by side are displayed. At this time, since only three related items are displayed for the related item display page information p1, the browsing rate is calculated as “1” using the first method of calculating the browsing rate, and the related item display page is displayed. For the information p2, since 20 related items are displayed vertically, it is calculated using the formula (2) of the second method of browsing rate calculation, and for the related item display page information p3 Since there are 10 rows of 30 related items arranged side by side, N = 3 may be calculated using equation (3). In this way, by changing the browsing rate calculation formula according to the page information, it is possible to calculate the browsing rate according to how the items are displayed.

Further, as shown in FIG. 13, a correspondence table in which page information and constants are associated with each other is stored in advance in a page information correspondence table storage unit (not shown) of the information processing server storage unit 13. A constant may be acquired as a browsing constant according to page information, and the acquired browsing constant may be used as a browsing rate. At this time, the browsing rate of each item identifier contained in the display information which has the same page information becomes the same value. Further, the browsing rate may be calculated so as to monotonously decrease in accordance with the display order after setting the browsing constant as the maximum value of the browsing rate.
In addition, regarding the display information corresponding to the related item display page information, when the display information includes a set identifier, the method of calculating the browsing rate to be used may be changed for each set identifier.
The above is the description of the browsing rate calculation method.

Next, the display information totaling unit 114 performs display totalization registration update processing for updating and registering the display total information (step S104). The display aggregation registration update process will be described later.
Next, the unprocessed display information acquired by the display information totalization unit 114 in step S101 is
It is determined whether or not all selections have been made in step S102 (step S105). If all are selected, the process proceeds to step S106. If unselected items still remain, step S
Proceed to 102.

In step S106, the display information aggregation unit 114 deletes the display aggregation information to be deleted from the display aggregation information storage unit 136, and ends a series of processing from step S101 to step S106. What is to be deleted in step 106 is display aggregate information relating to the user's items that have not been displayed for a predetermined period or longer determined by the service provider. For this, it is only necessary to delete the period between the time at the time of processing and the final display time information included in the display total information over a predetermined period. If the display aggregation information is not deleted, step S106 may be omitted. Moreover, you may perform the process regarding step S106 for every predetermined | prescribed timing predetermined by the service provision side instead of performing by a 1st display information total process.

Here, the procedure of the display aggregation registration update process in step S104 will be described with reference to FIG.
First, the display information totaling unit 114 selects one item identifier of the browsing rate calculation target item whose browsing rate is calculated in step S103, for example, in the order of dictionary of item identifiers (step S201).
Next, the display information totaling unit 114 stores in the display total information storage unit 136 the user identifier included in the display information selected in step S102, the key condition included in the display information selected in step S102, and step S201. It is determined whether or not there is display tabulation information that matches the item identifier selected in (Step S202). If it exists, step S20
Proceed to 3, and if it does not exist, proceed to step S204.

In step S203, the display information totaling unit 114 causes the display total information storage unit 136 to include the user identifier included in the display information selected in step S102, and the key condition included in the display information selected in step S102. The display total information that matches the item identifier selected in step S201 is specified, and the browsing rate total value and the final display time information of the specified display total information are updated as necessary. Next, the process proceeds to step S205.

There are the following two methods for updating the browsing rate aggregate value.
The first update method of the browsing rate total value is a method of adding the browsing rate calculated in step S103 to the browsing rate total value. At this time, the browsing rate total value is the sum of the browsing rates.

The second method of updating the browsing rate aggregate value is to calculate the update value of the browsing rate aggregate value using the average value of the browsing rate obtained by dividing the sum of the browsing rates by the number of display times and the display count, and the calculated update value Replace the browsing rate aggregate value with. Specifically, for example, the average value of the browsing rate for the item i corresponding to the key condition k of the user u is avr (u, k, i), the display count is c (u, k, i), and the display count After setting a constant δ (> 0) for adjusting the influence of, the browsing rate total value rt (u, k
, I) may be calculated using equation (5).

When “0 <δ <1”, the influence of the number of times of display becomes smaller than that of the first update method of the browsing rate update, and when “δ> 1”, the display rate is displayed by the first update method of the browsing rate update. The influence of times increases. In the case of “δ = 1”, since it is equal to the sum of the browsing rates, the influence of the number of display times is equivalent to the first updating method of the browsing rate update. Since the second update method of the browsing rate total value requires the sum of the browsing rates and the number of times of display, the total of the browsing rates and the number of times of display can be associated with the display total information and stored in the display total information storage unit 136. It is necessary to. Each time the display summary information is updated, the browsing rate is added to the sum of the browsing rates, and “1” is added to the display count.

The final display time information is updated only when the display time information included in the display information selected in step S102 is newer than the final display time information of the specified display aggregation information. When updating, the last display time information is updated with the display time information included in the display information selected in step S102.
In step S204, the display information totaling unit 114 includes the user identifier included in the display information selected in step S102, the key condition included in the display information selected in step S102, and the item identifier selected in step S201. Display aggregate information that associates the browsing rate calculated in step S103 with the browsing rate aggregate value and the display timing information included in the display information selected in step S102 as the final display timing information is displayed. Register in the total information storage unit 136. When the sum of the browsing rates and the display count are associated with the display total information, the sum of the browsing rates may be the browsing rate calculated in step S103, and the display count may be set to “1”.

In step S205, the display information totaling unit 114 determines whether or not all item identifiers included in the display information selected in step S102 have been selected in step S201.
If all are selected, the series of processing from step S201 to step S205 is terminated, and if there are still unselected items, the process proceeds to step S201.
The above is the description of the procedure of the display aggregation registration update process in step S104.
Since the first display information totalization process handles only unprocessed display information, the processing amount is small. For this reason, it is suitable for the case where it is performed every time display information is stored in the display information storage unit 135.
The above is the description of the procedure of the first display information aggregation process.

Next, the procedure of the second display information tabulation process will be described with reference to FIG.
First, the display information totaling unit 114 deletes all the display total information stored in the display total information storage unit 136 (step S301).
Next, the display information totaling unit 114 acquires all display information having display time information corresponding to a predetermined processing period from the display information storage unit 135 (step S302). The predetermined processing period may be a period that goes back a predetermined time (for example, one day, one week, one month, etc.) predetermined by the service provider from the time when the second display information aggregation processing is performed. Also in the second display information aggregation process, if the display information includes page information, only the display information satisfying the predetermined condition is acquired and the subsequent processes are performed as in the case of the first display aggregation process. You may go.

In step 102, if display information is selected from the display information acquired in step S302, the subsequent procedure is step S102 of the first display information aggregation process.
To step S105.
In the second display information totaling process, since the display total information is created from scratch, the processing amount is large, but the display total information can be generated using only display information corresponding to a predetermined processing period. Note that the second display information tabulation process has a large amount of processing, and is preferably performed at predetermined timings.
The above is the description of the procedure of the second display information aggregation process. The display information totaling unit 114 serves as a browsing rate total value calculation unit in the present embodiment.

When the display order determination unit 115 receives a related item acquisition request from the terminal device 3, the display order determination unit 115 performs display order determination processing. Moreover, the item detailed information transmission process which transmits item detailed information to the terminal device 3 is performed. When the related item selection unit 113 performs a related item selection process every time it receives a related item acquisition request from the terminal device 3, the display order determination unit 113 immediately after the related item selection process by the related item selection unit 113. 115 may perform display order determination processing.

First, the procedure of the display order determination process will be described with reference to the flowchart of FIG.
First, the display order determination unit 115 receives a related item acquisition request from the terminal device 3 via the network 2 (step S401).
Next, the display order determination unit 115 acquires related item information from the related item information storage unit 134 (step S402). When the related item information storage unit 134 has the first storage format, all the related item information including the key condition included in the related item acquisition request received in step S401 may be acquired. When the related item information storage unit 134 is in the second storage format, related item information including the key condition included in the related item acquisition request received in step S401 and the set identifier acquired using the related item acquisition request is displayed. All you have to do is get it. In order to acquire the set identifier, if the related item acquisition request received in step S401 includes the set identifier, it may be acquired as it is, or step S401.
The related item display page information is included in the related item acquisition request received at, and set determination information in which the related item display page information and the set identifier are associated is stored in the information processing server storage unit 13. What is necessary is just to acquire from the information processing server storage part 13. In addition, the information processing server storage unit 13 holds information about the page currently being browsed by the user corresponding to the user identifier included in the related item acquisition request received in step S401, and the information processing server storage unit Even when the set determination information is stored in 13, it may be acquired from the information processing server storage unit 13. In addition, you may acquire by excluding the item previously used by the user corresponding to the user identifier contained in the related item acquisition request received in step S401.

Next, the display order determination unit 115 selects one of the combination of the user identifier received in step S401 from the display total information storage unit 136 and the key condition and item identifier included in the related item information acquired in step S402. Get all the display summary information that matches
Step S403).
Next, the display order determination unit 115 calculates a priority for each item identifier included in the related item information acquired in step S402 (step S404).
Here, a method for calculating the priority will be described. Of the related item information, step S4
At 03, the browsing rate total value of the related item information for which the corresponding display total information could not be acquired is regarded as “0”.

The priority has such a property that the larger the relevance, the larger the value, and the smaller the browsing rate total value, the larger the value. Specifically, for example, the relevance level of the related item ir corresponding to the key condition k of the user u is v (u, k, ir), and the browsing rate total value rt (u, k, ir)
ir), constant γ1 (> 0), constant γ2 (> 0), constant γ3 (> 0), and constant γ4
By using (> 0) and the constant α5 (> 0), the priority pr (u, k, ir) can be calculated by Expression (6) or Expression (7).

In addition, the related item information acquired in step S402 is rearranged in the descending order of the degree of relevance, and the ranking is assigned in order from the first place, and the relation rank is used instead of the degree of relation. It is also possible to calculate the priority so that the higher the value is, the larger the value becomes. Specifically, for example, when the relation rank rankr (u, k, ir) of the related item ir corresponding to the key condition k of the user u is set, a constant γ5 (> 0), a constant γ6 (> 0), and a constant γ7 (> 0), constant γ8 (> 0), and constant α6 (> 0), the priority pr (u, k,
ir) can be calculated by Equation (8) or Equation (9).

Of course, the greater the degree of relevance, the larger the value, and the smaller the browsing rate aggregate value, the larger the value, or the higher the relevance ranking, the larger the value, and the browsing rate aggregated value becomes The priority may be calculated using any calculation formula as long as the calculation formula has any one of the properties that increase as the value decreases.

Next, the display order determination unit 115 assigns the display order from the first to the item identifier included in the related item information acquired in step S402 in order from the highest priority calculated in step S404 ( Step S405). When items used in the past are excluded from related items, items that were presented many times but never used under the same key conditions by assigning display order based on priority Display order can be lowered.

Next, the display order determining unit 115 receives the content information storage unit 132 from step S402.
The item information corresponding to the item identifier included in the related item information acquired in step S405 is acquired, sorted in the order of display order assigned in step S405, and then sorted to the terminal device 3 through the network 2 in the order of display order. Then, a set of item information associated with the display order is transmitted as related item detailed information (step S406), and a series of processing from step S401 to step S406 is completed. At this time, if the acquisition limit number is set in the related item acquisition request received in step S401, a set of item information up to the acquisition limit number from the top of the display order is set as the related item detailed information.

In addition, when the terminal device 3 divides and acquires related item detailed information, the related item detailed information created by performing the display order determination process is stored in the information processing server storage unit 13, and then the terminal device 3 3 of the stored related item detailed information in response to the request of 3
What is necessary is just to transmit the item information of the display order of the predetermined range designated by. For example, first, when a request for item information related to related items from the display order 1st to 5th is received from the terminal device 3, the related item detailed information created by performing the display order determination process,
After storing the information in the information processing server storage unit 13, the item information related to the related items from the first display position to the fifth display order, which is a part of the created related item detailed information, is transmitted to the terminal device 3. Next, from the terminal device 3 corresponding to the related item detailed information created earlier, the display order 6
When the request for the item information related to the related items from the first to the 20th is received, the display order determination process is not performed, and the related items from the display order 6th to the 20th which are a part of the related item detailed information created earlier are related. The item information may be transmitted to the terminal device 3.

As described above, the higher the degree of relevance indicating the degree of relevance between the key condition and the item, the higher the degree of relevance. By deciding the display order using priority with properties, items that are not viewed very often in the same key condition are likely to be higher, so it is related to the key condition. It is possible to present an item set related to a variety of key conditions while maintaining the accuracy of the item set to be displayed, so present related items that ensure both the reliability of related items and the maintenance of interest. Can do. The same effect is obtained when the priority is calculated using the related ranking and the browsing rate total value.

In addition, since the browsing rate aggregate value increases in proportion to the number of times related items are displayed, users who frequently display related items are frequently replaced with related items, but users who have a low number of related items are displayed. The ratio of replacing related items is automatically adjusted according to the browsing status of the related items of the user so that the related items are not replaced so much.
In addition, by adjusting the constant of the browsing rate calculation formula,
You can adjust how much related items are replaced.
The above is the description of the procedure of the display order determination process.

Next, item detailed information transmission processing will be described.
The item detailed information transmission process is a process of transmitting item detailed information other than related item detailed information to the terminal device 3. First, item information necessary for a page displayed on the terminal display unit 34 of the terminal device 3 is displayed as an item. All are acquired from the information storage unit 132. Next, item detailed information is created using the acquired item information. And the created item detail information,
It transmits to the terminal device 3.
The above is the description of the item detailed information transmission process.

An example of a series of procedures in which the terminal device 3 acquires related item detailed information and transmits a display history will be described with reference to the flowchart of FIG.
First, the terminal control unit 31 of the terminal device 3 performs a related item acquisition request transmission process, and transmits a related item acquisition request to the information processing server device 1 through the network 2 (step S501).
Next, when the related item selection unit 113 of the information processing server device 1 receives the related item acquisition request from the terminal device 3 through the network 2, the related item is acquired with respect to the key condition included in the received related item acquisition request. A selection process is performed (step S502).

Next, the display order determination unit 115 of the information processing server device 1 performs display order determination processing on the user identifier and key condition included in the related item acquisition request received in step S502, The related item detailed information corresponding to the related item acquisition request received in step S502 is transmitted to the device 3 (step S503).
Next, when the terminal control unit 31 of the terminal device 3 receives the related item detailed information corresponding to the related item acquisition request transmitted in step S501 from the information processing server device 1 through the network 2, the related item detailed information display is performed. Processing is performed (step S504).

Next, for the item information displayed on the terminal display unit 34 of the terminal device 3 among the item information of the related item included in the related item detailed information received by the terminal control unit 31 of the terminal device 3 in step S504. Then, display history transmission processing is performed, and the display history is transmitted to the information processing server device 1 through the network 2 (step S505).
Next, when the display information registration unit 112 of the information processing server device 1 receives a display history from the terminal device 3 through the network 2, a display information registration process is performed on the received display history (step S506). At this time, the display information created based on the display history received in step S506 is stored in the display information storage unit 135 as unprocessed display information.

Next, the display information totalization unit 114 of the information processing server device 1 performs processing on unprocessed display information.
Display information totaling processing is performed (step S507), and a series of processing from step 501 to step S507 is terminated.
In addition, when performing a related item selection process for every predetermined timing, step S50.
The process 2 may be skipped. In addition, when the display information aggregation process is performed at every predetermined timing, the process of step S507 may be skipped.
The above is an example of a series of procedures for acquiring the related item detailed information and transmitting the display history.

In the present embodiment, the display history is received from the terminal device 3, but the item displayed on the terminal display unit 34 of the terminal device 3 among the item detailed information without receiving the display order, If the final display order of the items to be displayed is clear, instead of receiving the display history from the terminal device 3, the display history is created by the display order determination process in the display order determination unit 115 or the item detailed information. Also good. At this time, the display information registration unit 112 may perform display information registration processing on the display history created by the display order determination unit 115.

Further, in the present embodiment, the display information storage unit 135 is prepared in the information processing server device 1. When the display information is used in this process, it may be appropriately acquired from the terminal storage unit of the terminal device 3. At this time, display information registration processing performed by the display information registration unit 112 needs to be performed by the terminal control unit of the terminal device 3.

Further, when a display information storage unit exists in a terminal storage unit (not shown) of the terminal device 3, a display total information storage unit is further prepared in the terminal storage unit, and then the display control unit 31 displays the display information total unit. The display information aggregation process in 114 may be performed, and the display aggregation information may be transmitted to the information processing server device 1 after the process is completed. In this case, the display information totaling unit 114 needs to store the display total information received from the terminal device 3 in the display total information storage unit 136. In addition, a display information storage unit and a display total information storage unit are prepared in a terminal storage unit (not shown) of the terminal device 3, and item information and related degree of related items are acquired from the information processing server device 1. The terminal control unit 31 of the terminal device 3 may calculate the priority.

The form of the service in which the effect by the first embodiment of the present invention is particularly high will be described below.

FIG. 18 is a configuration diagram of the information processing server device 5 in the present embodiment. The information processing server device 5 in this embodiment includes an information processing server control unit 51 and an information processing server communication unit 12.
And an information processing server storage unit 53.
The information processing server communication unit 12 is the same as that of the first embodiment of the present invention.

The information processing server storage unit 53 stores various data using a storage device such as a memory or an HDD. The information processing server storage unit 53 includes a user information storage unit 131, an item information storage unit 132, a usage history storage unit 133, a related item information storage unit 134, a display information storage unit 535, and a display total information storage unit 136. It consists of. A user information storage unit 131;
Item information storage unit 132, usage history storage unit 133, and related item information storage unit 134
The display total information storage unit 136 is the same as that of the first embodiment of the present invention.

The display information storage unit 535 stores a plurality of display information created based on the item detailed information transmitted to the terminal device 3. A method for creating display information in the present embodiment will be described later. FIG.
FIG. 9 is a diagram illustrating a storage state of display information. The display information is a user identifier (user_id
), Key condition (key), transmission time information (sent_date) that is the time information at which the item detailed information is transmitted, and display method information (disp_type) are associated with each other in a table format as shown in FIG. Remember. The display method information is information for specifying information related to items constituting the item detailed information and information such as how the item detailed information is displayed. Information on how it is displayed is
For example, information indicating how many items of detailed item information are displayed, page information regarding a page on which detailed item information is displayed, and the like. In the present embodiment, the display method information is the browsing specific information in the present embodiment, and the display information storage unit 535 is the browsing information storage unit in the present embodiment.

The information processing server control unit 51 performs overall control on each unit configuring the information processing server device 5. The information processing server control unit 51 includes a usage history registration unit 111, a related item selection unit 113, a display information aggregation unit 514, and a display order determination unit 515.
The usage history registration unit 111 and the related item selection unit 113 are the same as those in the first embodiment of the present invention.

Upon receiving a related item acquisition request from the terminal device 3, the display order determination unit 515 performs display order determination processing. Also, an item detail information transmission process is performed. In addition, related item selection part 1
13 performs a related item selection process each time a related item acquisition request is received from the terminal device 3, the display order determination unit 515 determines the display order immediately after the related item selection process by the related item selection unit 113. Processing may be performed.

First, the procedure of the display order determination process in this embodiment will be described with reference to the flowchart of FIG.
A series of processing from step S401 to step S406 is the same as that of the first embodiment of the present invention. When the processing up to step S406 ends, the process proceeds to step S707.

In step S707, the display order determination unit 515 creates display format information. In order to create the display format information, sufficient information is required to specify how to display on the terminal display unit 34 of the terminal device 3. For example, a page for displaying multiple item detailed information is required. If there is a display format defined for each page that displays item detail information, a page identifier that uniquely identifies the page that displays item detail information, such as the URL of the page or an identifier associated with the page May be created as display format information. The page identifier may be associated with the related item acquisition request received in step S401, or stored in the information processing server storage unit 53 in association with the user identifier included in the related item acquisition request received in step S401. In addition, the information may be acquired from the information processing server storage unit 53.

In addition, for a plurality of display formats used in the service, a display format identifier that uniquely identifies the display format may be set, and the display format identifier may be used as display format information. Similarly to the page identifier, the display format identifier may be associated with the related item acquisition request received in step S 401, or may be held in the information processing server storage unit 53. Further, instead of the information specifying the display format, for example, the top 10 display rankings are acquired and displayed as they are, or the top 20 display rankings are acquired, and 10 are randomly displayed from the acquired 20 As described above, information directly indicating the display format may be used as the display format information. Further, information that associates the item identifiers of all the items that are actually displayed with the final display order may be used as the display format information. Further, when the related item information storage unit 134 is in the second storage format, it is also necessary to associate a set identifier for specifying a set of related item information that is a creation source of the related item detailed information with the display format information. However, when the set identifier can be specified by other information such as a related item display page identifier, information for specifying the set identifier may be associated with the display format information instead of the set identifier.

Next, the display order determination unit 515 causes the display information storage unit 535 to include the user identifier included in the related item acquisition request received in step S401 and the key condition included in the related item acquisition request received in step S401. Then, the display information that associates the transmission time information that is the time information at which the related item detailed information has been transmitted to the terminal device 3 and the display format information created in step S707 is stored (step S708), and the series of processing ends.
In addition, although the process from step S707 to step S708 was demonstrated in the procedure performed after the process of step S406, as long as it is after step S401, it may be performed at any timing, and from step S402 to step S406. It may be performed in parallel with the processing.
The above is the description of the procedure of the display order determination process in the present embodiment.

Next, item detailed information transmission processing in the present embodiment will be described. The item detailed information transmission process in the present embodiment transmits the created item detailed information to the terminal device 3 in the same manner as the item detailed information transmission process in the first embodiment of the present invention. Display information is created, and the created display information is stored in the display information storage unit 535 in the same manner as the processing from step S707 to step S708 of the display order determination process.

The display information totaling unit 514 performs display information totaling processing.
The display information totaling process in the present embodiment may be performed every time display information is stored in the display information storage unit 535. Further, similarly to the related item selection process, it may be performed at predetermined timings predetermined on the service providing side.

Two types of display information aggregation processing procedures in this embodiment will be described below.
First, the first display information aggregation process in the present embodiment will be described with reference to FIG.
The first display information tabulation process in this embodiment is the first display information in the first embodiment of the present invention.
Since the process of step S103 of the display information totaling process of the above may be replaced with the process of step S803, the process of step S803 will be described.
In step S803, the display information totaling unit 514 uses the display information selected in step S802 to extract an item that is the target of browsing rate calculation (viewing rate calculation target item).
A browsing rate is calculated for each item identifier of the extracted browsing rate calculation target item.

The method of extracting the item identifier of the browsing rate calculation target item differs depending on the type of display format information included in the display information selected in step S102.
When the item identifier of the displayed item is included in the display format information, the item identifier may be extracted as the item identifier of the browsing rate calculation target item.

Further, when the display format information is related item display page information, the related item information stored in the related item information storage unit 134 and the display format information are included even if the item identifier of the displayed related item is not included. Thus, if the item identifier of the related item can be specified including the order displayed on the terminal display unit 34 of the terminal device 3, the specified item identifier may be extracted as the item identifier of the browsing rate calculation target item. At this time, past related item information is stored in the related item information storage unit 134 as necessary so that the related item information corresponding to the transmission time information included in the display information selected in step S102 can be acquired. Add an area to keep. Further, when the item identifier of the related item including the order displayed on the terminal display unit 34 of the terminal device 3 cannot be specified, it corresponds to the key condition and transmission time information included in the display information selected in step S102. What is necessary is just to extract as an item identifier of a browsing rate calculation object item from the collection of related item information to be.

In addition, when the related item information storage unit 134 is in the second storage format, when using the related item information stored in the related item information storage unit 134, information for specifying the set identifier is required. When creating the display format information that is a part of the display information in step S707 of the display order determination process, it is necessary to associate information for specifying the set identifier.

Next, a method for calculating the browsing rate will be described. The browsing rate calculation method can be calculated using the first method of browsing rate calculation according to the first embodiment of the present invention.

Moreover, when the last display order for every item can be specified, it can calculate using the 2nd method of browsing rate calculation.
In addition, when the terminal device 3 uses the specific rule and the random sort is performed, the item identifier and the final display order of the displayed item cannot be specified, but the specific rule can be determined. The following two calculation methods can be used.

The third method for calculating the browsing rate is a method of calculating a display probability estimated value that is an estimated value of a display probability that is a probability that a related item corresponding to the key condition is displayed as a browsing rate. For example, when the display probability estimated value is selected and displayed with 10 specific rules from 20 items in the terminal device 3, for example, the specific rule is randomly selected from up to 20 items with equal probability. If so, the display probability estimated value is “10/20 = 0.5”. In addition, when the specific rule is selected and displayed with 10 biased random items from the 20 items in the terminal device 3, 1000 trials are performed using the same specific rule as the terminal device 3,
As shown in FIG. 22, the display probability estimation value may be calculated by counting the number of display times in 1000 times for each related item corresponding to the key condition X and dividing the counted number of display times by the number of trial times 1000. In either case, the display probability estimation value of items whose display rank is 21st or higher is “0”. The third method of browsing rate calculation can increase the browsing rate of items that are likely to be actually displayed by estimating the display probability when an actually displayed item is not found. Of course, when the display probability can be directly acquired, the display probability may be directly treated as the display probability estimated value.

The fourth method for calculating the browsing rate is to estimate the expected value of the final display order given to the item in the terminal device 3 when the specific rule is biased random, and the estimated final display order This is a method of calculating the browsing rate so that the smaller the expected value, the larger the expected value. In addition,
For example, the expected value of the final display order is “0.2” for each key condition and for each item, and the probability that the final display order is second is “0.1”. This can be calculated when the display order probability, which is the probability for each final display order, is known. Specifically, if there are M items and the probability that the item i corresponding to the user u's key condition k is the display rank j is p (u, k, i, M, j), the final Expected display order value ev (
u, k, i, M) can be calculated by equation (10).

Even when the display order probability for each final display order is not known, for example, FIG.
As described above, using the same specific rule as that of the terminal device 3, the 20 items corresponding to the key condition X are sorted 1000 times, the average rank is calculated for each item, and the calculated average rank is calculated. May be the expected value of the final display order.

The average rank for an item is the display rank that is an estimate of the display rank probability for each final display rank by counting the number of times that rank was reached for each final display rank and dividing the counted number by the number of trials. It is also possible to calculate the expected value of the final display order by calculating the probability estimate and substituting the display order probability in Expression (10) with the display order probability estimate. Thus, if the expected value ev (u, k, i, M) of the final display order of the item i is estimated for each key condition and for each item, the viewing rate is given by rank (u, k) in the equation (2). , I) can be calculated by an expression in which ev (u, k, i, M) is replaced. Of course, as long as the expected value of the final display order becomes smaller, the browsing rate may be calculated by other methods as long as it becomes a larger value. The fourth method for calculating the browsing rate is to use the expected value of the final display order when the actually displayed item is not found, so that the terminal display unit 34 of the terminal device 3 actually uses the expected value at the top of the page. The browsing rate of items that are likely to be displayed can be increased.
The above is the method of calculating the browsing rate that can be used when the item identifier and final display order of the displayed item cannot be specified, but the specific rule can be determined.
The above is the description of the procedure of the first display information aggregation process.

Next, the procedure of the second display information tabulation process will be described with reference to FIG.
The second display information tabulation process in the present embodiment is the second display information aggregation process in the first embodiment of the present invention.
The processing in step S103 of the display information aggregation processing may be replaced with the processing in step S803. Regarding step S803, the same process as step S803 in the first display information totaling process in the present embodiment may be performed.
The above is the description of the procedure of the second display information aggregation process.

It should be noted that the display probability estimation information for estimating the display probability estimation value and the display rank estimation information for estimating the display rank estimation value are included in the display format information. Further, the display order probability may be treated as a display order probability estimate.

The form of the service in which the effect by the second embodiment of the present invention is particularly enhanced will be described below.
In a service where a large number of users frequently access and the load on the network is high, the display history is often not transmitted from the terminal device 3 in order to suppress the load on the network. Even in such a case, in this embodiment, by using the display information, the display order of the item set related to the key condition can be changed according to the viewing status of the user.

By using the present invention, by determining the display order of the related item detailed information corresponding to the related item acquisition request, in the order of high priority using the degree of association or the order of association, and the browsing rate aggregate value,
The accuracy of the entire item set related to key conditions can be maintained, and a variety of display results can be presented, enabling the display of related items that ensure both the reliability and interest of the user's related items. Thus, the use of the user's service can be promoted.
