[1. First Embodiment]
[1-1. Overview of information processing system configuration and functions]
First, the configuration of the information processing system S according to the present embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating an example of a schematic configuration of an information processing system S according to the present embodiment.

  As shown in FIG. 1, the information processing system S is configured to include a betting ticket sales agency server 1, a sponsor server 2, and a plurality of user terminals 3. The betting ticket sale agency server 1, the sponsor server 2, and each user terminal 3 can transmit and receive data to and from each other using, for example, TCP / IP as a communication protocol via the network NW. The network NW is constructed by, for example, the Internet, a dedicated communication line (for example, a CATV (Community Antenna Television) line), a mobile communication network (including a base station), a gateway, and the like.

  The betting ticket sale agency server 1 is a server device that performs various processes related to a horse racing site for selling betting tickets on behalf of a horse race organizer. The betting ticket sale agency server 1 is an example of an information processing apparatus according to the present invention. The betting ticket sales agency server 1 acquires information on the race announced by the organizer from the organizer server 2. The betting ticket sale agency server 1 transmits a web page in response to a request from the user terminal 3. Thereby, the betting ticket sale agency server 1 provides information on the race. Information provided includes, for example, race tables, odds, predictions, race results, and the like. In addition, the betting ticket sale agency server 1 performs, for example, a process of accepting purchase of a betting ticket or a process of refunding a hit betting ticket.

  When purchasing a betting ticket, a user of a horse racing site selects a purchase eye, the number of purchases, and the like. The buy eye includes a racehorse or a frame selected by the user (voting method) and selected by the user as a voting target. The racehorse or frame to be voted is specified by a horse number or a frame number. In the case of formulas that match not only the combination of horse numbers, but also the order of arrival, the purchase order includes the order of arrival for the racehorses to be voted on.

  Further, the betting ticket release agency server 1 accepts posting of a race prediction by the user based on a request from the user terminal 3. When posting a prediction, the user selects a favorite, a rival, a rival, a dark horse, and a lower level as a racehorse that is predicted to be in the higher order. A racehorse selected as one of a favorite, a challenge, a single hole, or a descendant is referred to as a predicted horse. The user can purchase a betting ticket based on the prediction posted by the user or the prediction of another person. For example, when the user selects a prediction, a candidate for purchase is displayed. The candidate selected for the purchase reflects the selected forecast. The user selects a purchase and purchases a betting ticket.

  When the user selects a betting ticket for a betting ticket or selects a predicted horse, the selection is made based on information on racehorses participating in the race. Information items used for selection include, for example, odds, horse weight, past race results, and the like. Examples of past race results include race time, number of wins, winning percentage, and the like. In general, the user does not look at every item equally but selects a running horse with emphasis on any item. Such items may vary from user to user. Items that are important to the user are referred to as priority items. Therefore, the betting ticket sale agency server 1 enables the user to specify important items in order to assist the user in selecting a running horse. Then, the betting ticket sale agency server 1 performs a process for recommending to the user a running horse to be selected as an expected horse or a buying eye based on the designated priority item. A running horse recommended for a user is called a recommended horse. Details of the recommended horse identification method will be described later.

  The sponsoring server 2 is a server device that is installed in order for the horse racing organizer to provide race information or issue a betting ticket. The sponsoring server 2 transmits information on the race to the betting ticket sales agency server 1.

  The user terminal 3 is a terminal device of a user who uses the horse racing site. The user terminal 3 receives and displays a web page from the betting ticket sales agency server 1 by accessing the betting ticket sales agency server 1 based on an operation from the user. Software such as a browser and an e-mail client is incorporated in the user terminal 3. As the user terminal 3, for example, a personal computer, a PDA (Personal Digital Assistant), a portable information terminal such as a smartphone, a mobile phone, or the like is used.

[1-3. Details of system control function]
Next, the function of the system control unit 14 will be described with reference to FIGS. FIG.2 (b) is a figure which shows an example of the functional block of the system control part 14 of the betting ticket sale agency server 1 which concerns on this embodiment. As shown in FIG. 2B, the system control unit 14 reads and executes a program such as a betting ticket issuance agency management program by the CPU 14a, so that an important item acquisition unit 141, a running horse information acquisition unit 142, and a selected horse recommendation It functions as the unit 143 and the like. The emphasis eye acquisition unit 141 is an example of an item acquisition unit in the present invention. The racehorse information acquisition unit 142 is an example of a race target information acquisition unit and a second race target identification unit in the present invention. The selected horse recommendation unit 143 is an example of a race target specifying unit and a presentation control unit in the present invention.

  The system control unit 14 specifies a recommended horse to be selected as an expected horse or a buy eye based on the priority items, and presents the recommended horse to the user. Therefore, the emphasis item acquisition unit 141 acquires information on a plurality of running horses in a race and items that the user attaches importance to among the plurality of items that can compare the superiority and inferiority of the plurality of running horses. Comparing superiority or inferiority of a running horse means, for example, that it is possible to compare the probability that a running horse will win a higher rank. Examples of such items include odds (single win odds), horse weight, horse weight increase / decrease, past race time, number of wins, winning rate, and the like. The lower the odds, the better. Horses that run lighter are more competitive. Running horses with smaller changes in horse weight are more dominant. The shorter the race time, the better. The more the horses that win the race, the better. The higher the winning rate, the more competitive. Note that items that can be designated as priority items are not limited to the items described above as long as the items can be compared for superiority or inferiority of a plurality of running horses.

  For example, a user may want to know which racehorse to select for a race before posting predictions or purchasing a betting ticket. In this case, the user specifies the target race and specifies the priority item. The races that can be specified are races for which the betting ticket sales deadline has not yet passed. At this time, the user may designate a plurality of important items. In addition, when past results such as race time, number of wins, winning percentage, etc. are designated as priority items, the user may be able to designate past race conditions. As such a condition, for example, grade, distance, racetrack, racetrack, clockwise or counterclockwise may be specified. Further, for example, it may be possible to designate the race on the condition that the race is a past race in which the same person as the jockey who rides in the designated race is riding. A plurality of conditions may be specified.

  The user terminal 3 transmits important item information including the race ID of the designated race and the item ID of the designated item to the betting ticket release agency server 1. The priority item acquisition unit 141 acquires the race ID and the priority item information transmitted from the user terminal 3. The race indicated by the race ID acquired by the priority item acquisition unit 141 is referred to as a designated race. The priority item information acquired at this time indicates the priority item of a specific race. The priority item acquisition unit 141 registers the acquired race ID, the priority item information, and the user ID of the user who has performed the designation operation in association with each other in the priority item information DB 12e for each race.

  The starting horse information acquisition unit 142 is information on a plurality of starting horses of a race determined based on a predetermined condition, and the priority item indicated by the item ID included in the priority item information acquired by the priority item acquisition unit 141 Get information corresponding to. Specifically, when the priority item is odds, the racehorse information acquisition unit 142 acquires win odds from the odds information DB 12d. On the other hand, when the priority item is not odds, the racehorse information acquisition unit 142 acquires information corresponding to the priority item from the racehorse information registered in the race information DB 12b. The main condition among the race conditions for acquiring information on the starting horse is that the betting ticket sales deadline has not yet passed. That is, it is possible to purchase a betting ticket and post a prediction. And when the race ID of the designated race is acquired by the priority item acquisition unit 141, the condition of the race for acquiring the information of the running horse is that it is the specified race. In this case, the racehorse information acquisition unit 142 acquires information on the designated race.

  The selected horse recommendation unit 143 is the emphasis acquired by the emphasis item acquisition unit 141 among a plurality of race horses determined based on predetermined conditions based on the information acquired by the race horse information acquisition unit 142. One or more running horses that are relatively dominant in the item are identified as recommended horses. When a user attaches importance to an item, there is a high probability that the user selects a racehorse that is relatively superior in the item to be emphasized. Therefore, it is possible to appropriately specify a running horse that has a probability of being selected by the user. The number of recommended horses may be one or more and less than the total number of running horses. For example, the number of recommended horses may be determined in advance. At this time, the number of recommended horses may be determined according to the number of running horses participating in the race. For example, the user may be able to set the number of recommended horses. For example, the selected horse recommendation unit 143 may specify the recommended horse at the timing when the important item information is acquired from the user terminal 3, or specifies the recommended horse at the predetermined timing after the important item information is acquired. May be. When the recommended horse is specified, the selected horse recommendation unit 143 registers recommended horse specifying information indicating the specified recommended horse in the priority item information DB 12e by race.

  A specific example will be described below. FIG. 5A is a diagram illustrating an example of designated important items. For example, as shown in FIG. 5A, it is assumed that the user has designated the race time (1700 meters, light-track) as an important item in the first race on a certain day. FIG.5 (b) is a figure which shows the example of the information of the run horse of the 1st race. For convenience of explanation, it is assumed that there are six race horses participating in each race. In FIG. 5 (b), as an example, odds, race time (1700 meters, light racetrack), race time (1700 meters, heavy racetrack), number of wins, and horse weight of each running horse are shown. The selected horse recommendation unit 143 determines the superiority or inferiority rank of each running horse in the priority item. The superiority / inferiority rank is a rank when the ranks of the respective running horses are determined in the dominant order. As shown in FIG. 5B, in the race time (1700 meters, light racetrack), the superiority and inferiority ranks are higher in the order of horse numbers 1, 2, 3, 4, 5, and 6. Therefore, the selected horse recommendation unit 143 may specify the running horses of horse numbers 1, 2, and 3 as recommended horses, for example.

  When the recommended horse is specified, the priority item specifying unit 143 may determine a purchase including the recommended horse. For example, the type of purchase may be determined in advance. Further, for example, the user may be able to set the formula in advance. Further, the selected horse recommendation unit 143 may determine a purchase according to the number of specified recommended horses. For example, the selected horse recommending unit 143 may determine a formula according to which the number of starting horses to be selected increases as the number of recommended horses increases. When deciding on a buy-by-expression buy that hits the arrival order, the priority item specifying unit 143 may, for example, make the arrival order earlier for a running horse having a higher priority. FIG. 5C is a diagram illustrating an example of buying eyes. The priority item specifying unit 143 determines, for example, horse units 1-2, 1-3, and 2-3 as buying eyes.

  The selected horse recommendation unit 143 causes the user terminal 3 to present the specified recommended horse to the user. For example, the selected horse recommendation unit 143 causes the user terminal 3 to display on the screen recommended horse information including the racetrack name of the designated race, the race number, the race date, the recommended horse number (buy information), and the like. . FIG. 5D is a diagram illustrating a screen display example of recommended horse information. By providing the user terminal 3 with a horse that is relatively dominant in the priority item, it is possible to support the selection of the horse by the user. For example, the user terminal 3 may display recommended horse identification information in a pop-up, or may display recommended horse information on a web page indicating completion of registration of the important items. Further, the selected horse recommendation unit 143 may present the recommended horse at the timing when the recommended horse is identified, or may present the recommended horse at a predetermined timing after identifying the recommended horse. For example, when the user views a web page related to a certain race, the selected horse recommendation unit 143 may present a recommended horse specified for the race.

  The selected horse recommendation unit 143 may determine a favorite, a challenge, a single hole, and a descendant, for example, in the order of recommended horses having higher and lower ranks, instead of determining a purchase. And the selection horse recommendation part 143 may show a favorite, a countermeasure, a single hole, and a descendant. Further, only the horse number may be displayed.

  When a plurality of priority items are designated, the selected horse recommendation unit 143 may specify, for example, a running horse included in a relatively dominant starting horse as a recommended horse in all of the plurality of priority items. Good. For example, it is assumed that the priority items of the first race are race time (1700 meters, light racetrack) and horse weight. As shown in FIG. 5 (b), in the first race, the superiority or inferiority rank is higher in the horse weight in the order of horse numbers 4, 1, 2, 3, 6, and 5. In each priority item, it is assumed that the horses with the superiority or inferiority ranking of 3 or more are relatively dominant horses. In the first race, the race horses whose race times (1700 meters, light horse race) and horse weight are superior or inferiority rank 3 or higher are race Nos. 1 and 2. Therefore, the selected horse recommendation unit 143 identifies the running horses of horse numbers 1 and 2 as recommended horses.

  Information about running horses may be updated before the betting ticket purchase is closed. For example, the odds are updated from time to time. In addition, information other than odds may be updated. When information on items that are important to the user is updated, the recommended horse may also change. Therefore, the system control unit 14 may specify the recommended horse based on the updated information when the information on the items that the user attaches importance to is updated. Specifically, when the racehorse information registered in the race information DB 12b or the odds information registered in the odds information DB 12d is updated, the racehorse information acquisition unit 142 includes the race ID of the race whose information is updated, The item ID of the item whose information has been updated and the updated information are acquired. The selected horse recommendation unit 143 includes the item ID acquired by the racehorse information acquisition unit 142 among the priority item information corresponding to the race ID acquired by the racehorse information acquisition unit 142 from the race-specific priority item information DB 12e. Search important item information. Next, the selected horse recommendation unit 143 acquires a user ID corresponding to the searched important item information. And the selection horse recommendation part 143 specifies a recommendation horse based on the information after an update. The selected horse recommendation unit 143 updates the recommended horse specifying information registered in the race-specific important item information DB 12e with the recommended horse specifying information indicating the specified new recommended horse. The selected horse recommendation unit 143 also presents the specified recommended horse. For example, the selected horse recommendation unit 143 may transmit information of the specified recommended horse by an e-mail addressed to the user indicated by the acquired user ID. For example, when the user indicated by the acquired user ID is logging in to the horse race site, the selected horse recommendation unit 143 may transmit the recommended horse information to the user terminal 3 used by the user. Further, for example, the selected horse recommendation unit 143 may transmit the recommended horse information to the user terminal 3 used by the user at the timing when the user indicated by the acquired user ID logs in to the horse racing site. For example, when the user indicated by the acquired user ID browses a web page related to a certain race, the selected horse recommendation unit 143 may present the recommended horse specified for the race.

  The selected horse recommendation unit 143 may identify and present a recommended horse for a race other than the race for which an important item is designated by the user. In this case, the selected horse recommendation unit 143 may specify the recommended horse based on the user-oriented item. Specifically, the priority item acquisition unit 141 acquires a plurality of priority item information registered in the priority item information DB 12e for a certain user. Race conditions for acquiring the important item information may be determined in advance. For example, the emphasis item acquisition unit 141 may acquire emphasis item information of a race held in the past predetermined period. For example, the priority item acquisition unit 141 may acquire priority item information of a race held on the previous day. The priority item acquisition unit 141 calculates, for each item, the number of times the user has specified the priority item based on, for example, the item ID included in the priority item information. Then, the emphasis item acquisition unit 141 acquires, as user emphasis items, items having a relatively large number of designated times from among the emphasis items indicated by the acquired plurality of emphasis item information. For example, the priority item acquisition unit 141 may determine the item with the largest specified number of times as the user priority item, or determine one or more items whose specified ratio is equal to or greater than a predetermined ratio as the user priority item. May be. The priority item acquisition unit 141 registers the priority item information including the item ID of the user priority item in the user priority item information DB 12f in association with the user ID of the target user.

  The race that presents the recommended horse is, for example, a race for which the betting ticket sales deadline has not yet passed. For example, the race that presents the recommended horse may be all the races scheduled to be held today. The starting horse information acquisition unit 142 is information on a starting horse of a race for presenting a recommended horse, and acquires information corresponding to the user emphasis item acquired by the emphasis item acquisition unit 141. For example, the selected horse recommendation unit 143 may acquire information on all the races scheduled to be held today.

  The selected horse recommendation unit 143 specifies a recommended horse for each race based on the information acquired by the racehorse information acquisition unit 142. When an important item has already been registered for a certain race, for example, the selected horse recommending unit 143 may not specify a recommended horse for the race, or information on the important item of the race and information on the user-oriented item. Based on the above, a running horse that is relatively dominant in the priority items of the race and the priority items of the user may be specified as the recommended horse. Further, when the recommended horse specifying information is already registered for a certain race, the selected horse recommendation unit 143 may not specify the recommended horse for the race, for example.

  When the selected horse is specified, the selected horse recommendation unit 143 presents the recommended horse. For example, the selected horse recommendation unit 143 may transmit the recommended horse information to the user terminal 3 at the timing when the user logs into the horse racing site. Further, for example, when the user browses a web page related to a certain race, the selected horse recommendation unit 143 may present a recommended horse specified for the race.

  Further, the selected horse recommendation unit 143 may identify and present recommended horses for races other than the designated race based on the priority items of the designated race. The reason is that when the user designates an item to be emphasized for a certain race, there is a probability that the same item is emphasized for other races. Specifically, the racehorse information acquisition unit 142 acquires information on a plurality of racehorses in a race different from the designated race, and information corresponding to the priority items of the designated race. Based on the information acquired by the starting horse information acquisition unit 142, the selected horse recommendation unit 143 identifies starting horses that are relatively dominant in the priority items of the specified race among the plurality of starting horses different from the specified race. . The race that presents the recommended horse may be, for example, all the races scheduled to be held today. In addition, the race that presents the recommended horse may be, for example, all the races scheduled to be held on the same day as the designated race, or all the races scheduled to be held on the same race track on the same day as the designated race. Good.

[1-4. Operation of information processing system]
Next, the operation of the information processing system S will be described with reference to FIGS. FIG. 6 is a flowchart showing a processing example of the priority item registration processing by race by the system control unit 14 of the betting ticket release agency server 1 according to the present embodiment. For example, in order to register an important item for a certain race, the user designates the race and the important item. Then, the user terminal 3 transmits a priority item registration request to the betting ticket sale agency server 1. The priority item registration request includes the race ID of the designated race and the priority item information storing the item ID of the priority item. The system control unit 14 executes an important item registration process when receiving an important item registration request from the user terminal 3.

  As illustrated in FIG. 6, the priority item acquisition unit 141 acquires the race ID and priority item information of the designated race from the received priority item registration request, and uses the user terminal 3 that has transmitted the priority item registration request. The user ID of the user is acquired (step S1). For example, the user inputs a user ID when logging in to the horse racing site in advance, and the user terminal 3 transmits the input user ID to the betting ticket release agency server 1. The system control unit 14 stores the received user ID in the RAM 14c or the like in association with the session ID, for example. Then, the system control unit 14 transmits the session ID as a cookie to the user terminal 3. Thereafter, the session ID is added to the request transmitted from the user terminal 3 to the betting ticket sale agency server 1. The selected horse information acquisition unit 141 can acquire a user ID based on the session ID. Subsequently, the priority item acquisition unit 141 registers the acquired race ID, priority item information, and user ID in association with each other in the priority item information DB 12e for each race (step S2).

  Next, the selected horse recommendation unit 143 executes a recommended horse specifying process (step S3). In the recommended horse specifying process, the selected horse recommendation unit 143 specifies a recommended horse and generates recommended horse specifying information. Details of the recommended horse specifying process will be described later. Next, the selected horse recommendation unit 143 registers the generated recommended horse identification information in the priority item information DB 12e for each race in association with the race ID and the user ID of the designated race acquired by the priority item acquisition unit 141 (step) S4). Next, the selected horse recommendation unit 143 generates recommended horse information based on the race ID of the designated race and the recommended horse specifying information. Then, the selected horse recommendation unit 143 transmits the generated recommended horse information to the user terminal 3 (step S5). When step S5 is completed, the selected horse recommendation unit 143 ends the weighted item registration process. The user terminal 3 that has received the recommended horse information displays the recommended horse information on the screen.

  FIG. 7 is a flowchart showing a processing example of a recommended horse specifying process by the system control unit 14 of the betting ticket release agency server 1 according to the present embodiment. As shown in FIG. 7, the racehorse information acquisition unit 142 acquires information corresponding to the priority item among the information of the plurality of racehorses corresponding to the race ID of the recommendation target race (step S11). When the recommended horse specifying process is executed from the priority item registration process for each race, the recommended race is the designated race. When the item ID included in the priority item information acquired in the priority item registration process for each race indicates odds, the racehorse information acquisition unit 142 determines from the odds corresponding to the race ID of the recommended race from the odds information DB 12d. Get win odds for each racehorse. When the item ID indicates an item different from odds, the racehorse information acquisition unit 142 acquires information corresponding to the item indicated by the item ID from the racehorse information corresponding to the race ID of the race to be recommended in the race information DB 12b. To do.

  Next, the selected horse recommendation unit 143 determines the superiority or inferiority rank of each running horse in the recommended race based on the information acquired by the running horse information acquisition unit 142 in the priority items of the recommended race (step S12). ).

  Next, the selected horse recommendation unit 143 identifies a relatively dominant running horse among the plurality of running horses of the recommendation target race as the recommended horse in the priority item of the recommendation target race (step S13). For example, the number N of recommended horses may be set in advance. In this case, the selected horse recommendation unit 143 may determine a running horse having a superiority or inferiority ranking of N or more as a recommended horse. When there are a plurality of priority items for the designated race, the selected horse recommendation unit 143 may specify a running horse having a superiority or inferiority ranking of N or higher for each priority item, for example. And the selection horse recommendation part 143 may determine the run horse whose superiority / inferiority rank is N or more in all the important items as a recommended horse.

  Next, the selected horse recommendation unit 143 generates recommended horse specifying information including the horse number of the specified recommended horse (step S14). At this time, the selected horse recommendation unit 143 may generate predicted horse information or buy eye information including the horse number of the recommended horse. Then, the selected horse recommendation unit 143 may generate recommended horse specifying information including the generated predicted horse information or buy eye information. When step S14 is completed, the selected horse recommendation unit 143 ends the recommended horse specifying process.

  Note that when the priority item information is registered in the user priority item information DB 12f in association with the user ID acquired in the race-specific priority item registration process, the system control unit 14 determines the priority item information of the designated race and the user priority. Based on the item information, a running horse that is relatively dominant in the priority item of the designated race and the user priority item may be specified as the recommended horse.

  FIG. 8 is a flowchart showing a processing example of user-oriented item registration processing by the system control unit 14 of the betting ticket release agency server 1 according to the present embodiment. The user-focused item registration process is a process for registering a user-focused item. The system control unit 14 executes user-oriented item registration processing at a predetermined timing. For example, the system control unit 14 may execute the user-oriented item registration process for each user once a day in order to register the user-oriented items of all users. For example, the system control unit 14 may execute the user-focused item registration process for the user in which the focus item is registered, when the race-specific focus item registration process ends.

  As shown in FIG. 8, the racehorse information acquisition unit 142 acquires the user ID of the user to be registered as the user-oriented item (step S21). Next, the racehorse information acquisition unit 142 acquires priority item information corresponding to the acquired user ID from the priority item information DB 12e by race (step S22). At this time, the racehorse information acquisition part 142 acquires all the important item information of the race held for a predetermined period, for example.

  Next, the important item acquisition unit 141 calculates the number of designated important items for each item based on the item ID included in the acquired important item information (step S23). That is, the important item acquisition unit 141 calculates, for each item, the number of item IDs included in the important item information. Next, the emphasis item acquisition unit 141 determines one or more items with a relatively large number of designated times as user emphasis items (step S24). Next, the priority item acquisition unit 141 registers the priority item information including the item ID of the user priority item in the user priority item information DB 12f in association with the user ID acquired in Step S21 (Step S25). When step S25 ends, the priority item acquisition unit 141 ends the user priority item registration process.

  FIG. 9 is a flowchart showing a processing example of a multi-race selection horse recommendation process by the system control unit 14 of the betting ticket release agency server 1 according to the present embodiment. The multiple race selection horse recommendation process is a process for recommending a recommended horse for a plurality of races based on the user-oriented items. The system control unit 14 executes a multiple race selection horse recommendation process at a predetermined timing. For example, the system control unit 14 may execute the multiple race selection horse recommendation process at the timing when the user logs in to the horse racing site.

  As illustrated in FIG. 9, the priority item acquisition unit 141 acquires the user ID of the recommendation target user and acquires the priority item information corresponding to the recommendation target user ID from the user priority item information DB 12f (step S31). . Next, the selected horse recommendation unit 143 acquires all the race IDs of the races for which the betting ticket sales deadline has not passed from the race information DB 12b (step S32). Next, the selected horse recommendation unit 143 selects one of the acquired race IDs (step S33).

  Next, the selected horse recommendation unit 143 executes a recommended horse specifying process (step S34). In the recommended horse identification process, the racehorse information acquisition unit 142 uses the race indicated by the selected race ID as the recommendation race, and is the information about the racehorse of the race to be recommended and the priority item acquired in step S31 Information corresponding to the user-oriented item indicated by the information is acquired. Then, the selected horse recommendation unit 143 identifies recommended horses that are relatively dominant in the user-focused items for the recommendation target race. The recommended horse specifying process in this case is basically the same as the process shown in FIG. Next, the selected horse recommendation unit 143 registers the recommended horse specifying information generated in the recommended horse specifying process in the priority item information DB 12e by race in association with the selected race ID and the user ID of the user to be recommended ( Step S35).

  Next, the selected horse recommendation unit 143 determines whether or not there is an unselected race ID in the acquired race ID (step S36). At this time, if the selected horse recommendation unit 143 determines that there is a race ID that has not yet been selected (step S36: YES), the process proceeds to step S37. In step S37, the selected horse recommendation unit 143 selects one race ID that has not yet been selected. Next, the selected horse recommendation unit 143 proceeds to step S34.

  On the other hand, if the selected horse recommendation unit 143 determines that all race IDs have been selected (step S36: NO), the process proceeds to step S38. In step S38, the selected horse recommendation unit 143 generates recommended horse information for each recommended horse specifying information registered in the race-specific important item information DB 12e in step S35. Then, the selected horse recommendation unit 143 transmits all the generated recommended horse information to the user terminal 3 of the user to be recommended. When step S38 is completed, the selected horse recommendation unit 143 ends the multiple race selection horse recommendation process. The user terminal 3 displays each recommended horse information received from the betting ticket sale agency server 1 on the screen.

  As described above, according to the present embodiment, the system control unit 14 acquires items that the user places importance on from among a plurality of items of information that can compare the superiority and inferiority of a plurality of running horses participating in a race. Further, the system control unit 14 acquires information on a plurality of running horses participating in a race determined based on a predetermined condition and corresponding to the acquired priority item. Further, the system control unit 14 identifies one or more running horses that are relatively dominant in the priority items among the plurality of running horses participating in the determined race based on the acquired information. Then, the system control unit 14 presents the specified running horse. Therefore, the user can know a running horse that has a probability of being selected by the user.

[2. Second Embodiment]
Next, a second embodiment will be described. In the present embodiment, when there are a plurality of priority items, the betting ticket release agency server 1 acquires the weight of each priority item, and determines the superiority of each of the plurality of running horses based on the weight. Then, the betting ticket release agency server 1 specifies a recommended horse based on the degree of superiority. In other respects, the present embodiment is the same as the first embodiment.

[2-1. Details of system control function]
First, the functional outline of the system control unit 14 of the betting ticket sale agency server 1 will be described with reference to FIG. When the user designates a plurality of important items, for example, the priority of each important item may be designated. The priority items with higher priority are items that the user attaches importance to. This priority may be, for example, a priority order. This priority is called item priority.

  The selected horse recommendation unit 143 may acquire the weight of each important item according to the item priority. For example, this weight is represented by a coefficient. The higher the item priority, the larger the weighting factor. The weighting factor may be set in advance, for example. Moreover, the weighting coefficient of each important item may be set in advance according to the number of important items. Further, instead of the item priority order, the user may be able to specify the weight of each important item.

  The priority item acquisition unit 141 may also determine the item priority when determining a plurality of user priority items. For example, the priority item acquisition unit 141 may increase the item priority order as the user priority item has a larger number of designations. Further, the importance item acquisition unit 141 may determine the weight of each user importance item according to the designated number of times instead of determining the item priority. In the present embodiment, the priority item information is stored for each priority item, for example, in association with the item ID and the item priority.

  The selected horse recommending unit 143 may determine the superiority of each starting horse based on the information on each starting horse and the weighting factor of each important item, and may identify one or more recommended horses based on the superiority. . The superiority indicates the degree of relative advantage of each running horse when a plurality of important items are combined. The superiority is information that allows comparison of superiority or inferiority of a plurality of running horses in a plurality of items.

  A specific example will be described below. FIG. 10A is a diagram illustrating an example of designated importance items. For example, as shown in FIG. 10A, it is assumed that the user designates the race time (1700 meters, light horse race) and the horse weight as important items in the first race. At this time, the user specified the item priority of the race time (1700 meters, light horse riding) as the first place and the item priority of the horse weight as the second place. For example, it is assumed that the weight coefficient of the item having the first item priority is 0.7 and the weight coefficient of the item having the second priority is 0.3. FIG. 10B is a diagram illustrating an example of the information on the horses in the first race in the superiority / inferiority ranking of each item. As shown in FIG. 10B, in the race time (1700 meters, light racetrack), the superiority and inferiority ranks are higher in the order of horse numbers 1, 2, 3, 4, 5, and 6. Moreover, in the horse weight, the superiority / inferiority rank is higher in the order of horse numbers 4, 1, 2, 3, 6, and 5. A basic point is given to the superiority or inferiority ranking of each item. For example, 1st place is 6 points, 2nd place is 5 points, 3rd place is 4 points, 4th place is 3 points, 5th place is 2 points, 6th place is 1 point.

  The selected horse recommendation unit 143 multiplies the basis point corresponding to the superiority or inferiority rank in each priority item by each weighted horse, calculates the superiority in the priority item, and the total value of the superiority of all the priority items Is calculated as the superiority of the running horse. FIG.10 (c) is a figure which shows the example of the superiority of each running horse in the 1st race. For example, the superiority or inferiority ranking in the race time (1700 meters, light-track) of a running horse whose horse number is 1 is 1st. The odds of running horses with horse number 1 are 2nd place. In this case, the superiority of the running horse whose horse number is 1 is 0.7 × 6 + 0.3 × 5 = 5.7. Similarly, the respective superiorities of the running horses whose horse numbers are 2 to 6 are 4.7, 3.7, 3.9, 1.7, and 1.3. For example, when three starting horses are selected in descending order of superiority, the starting horses of horse numbers 1, 2, and 4 become recommended horses. In this case, for example, horses 1-2, 1-4, and 2-4 may be presented as recommended buying eyes. FIG. 10D is a diagram illustrating an example of recommended buying eyes. Further, for example, the selected horse recommendation unit 143 may select a running horse whose superiority is equal to or higher than the average of the superiority of all the running horses. In this case, horses with horse numbers 1, 2, 4, and 3 are recommended horses. In this case, for example, horses 1-2, 1-4, 1-3, 2-3, 2-3, 4-3 may be presented as recommended buying eyes.

[2-2. Operation of information processing system]
Next, the operation of the information processing system S will be described with reference to FIG. FIG. 11 is a flowchart showing a processing example of recommended horse specifying processing by the system control unit 14 of the betting ticket release agency server 1 according to the present embodiment. In FIG. 11, processes similar to those in FIG.

  As shown in FIG. 11, the selected horse recommendation unit 143 sets the item priority order i to 1 (step S41). Next, the selected horse recommendation unit 143 acquires an item ID corresponding to the item priority order i from the priority item information. And the racehorse information acquisition part 142 acquires the information corresponding to the important item which acquired item ID shows among the information of the some racehorse corresponding to race ID of the race of recommendation object (step S42). Next, the selected horse recommendation unit 143 determines the superiority or inferiority ranking of each running horse of the recommended race in the priority item indicated by the acquired item ID based on the information acquired by the starting horse information acquisition unit 142 (step) S43). Next, the important item acquisition unit 141 acquires the basis point of each superiority or inferiority and the weight coefficient of the item priority i from the storage unit 12 (step S44). Next, the selected horse recommendation unit 143 multiplies the acquired weighting factor for each starting horse by the base point corresponding to the superiority or inferiority ranking of the starting horse, and the item superiority of each starting horse in the priority item of the item priority i Is calculated (step S45).

  Next, the selected horse recommendation unit 143 determines whether or not the item priority order i matches the number of item IDs included in the important item information (step S46). At this time, if the selected horse recommendation unit 143 determines that the item priority order i does not match the number of item IDs (step S46: NO), the process proceeds to step S47. In step S47, the selected horse recommendation unit 143 adds 1 to the item priority order i. Next, the selected horse recommendation unit 143 proceeds to step S42. On the other hand, if the selected horse recommendation unit 143 determines that the item priority order i matches the number of item IDs (step S46: YES), the selection horse recommendation unit 143 proceeds to step S48.

  In step S <b> 48, the selected horse recommendation unit 143 calculates the superiority by adding the item superiorities of all the important items for each running horse. Next, the selected horse recommendation unit 143 determines one or more running horses having a relatively high superiority among the plurality of running horses as recommended horses (step S49). For example, the selected horse recommendation unit 143 determines the rank in the order of running horses having a relatively high degree of superiority. For example, when the number N of recommended horses is determined in advance, the selected horse recommendation unit 143 determines a running horse whose superiority rank is N or more as a recommended horse. Next, the selected horse recommendation unit 143 generates recommended horse specifying information (step S14), and ends the recommended horse specifying process.

  As described above, according to the present embodiment, the system control unit 14 acquires a plurality of important items and respective weights of the plurality of important items. In addition, the system control unit 14 determines the superiority of each of the plurality of running horses based on the information and weight of the running horse, and based on the superiority, one or more relatively superior in the plurality of important items Identify the starting horse. Therefore, when a user attaches importance to a plurality of items, the betting ticket sale agency server 1 can present a running horse corresponding to the degree to which the user attaches importance to each of the plurality of items.

[3. Third Embodiment]
Next, a third embodiment will be described. When the betting ticket release agency server 1 identifies a preset number of relatively dominant horses in the current priority item, between the relatively dominant horse and the relatively inferior horse The difference between superiority and inferiority may not be significant. In other words, it is not possible to clearly distinguish between a relatively dominant horse and a relatively inferior horse. In this state, there is a probability that the selection criteria for the recommended horse are ambiguous. In such a case, when other items are taken into consideration in addition to the current priority items, there may be a significant difference between superiority and inferiority between a relatively dominant horse and a relatively inferior horse. In this embodiment, the betting ticket sale agency server 1 specifies an item recommended to the user as an important item to be added in such a case. This item is called a recommended item. In other respects, the present embodiment is the same as the first embodiment or the second embodiment.

[3-1. Details of system control function]
Next, the functional outline of the system control unit 14 of the betting ticket sale agency server 1 will be described with reference to FIGS. 12 and 13. FIG. 12 is a diagram illustrating an example of functional blocks of the system control unit 14 of the betting ticket release agency server 1 according to the present embodiment. As illustrated in FIG. 12, the system control unit 14 includes an important item acquisition unit 141, a running horse information acquisition unit 142, a selected horse recommendation unit 143, an important item obvious superior horse specifying unit 144, a candidate item specifying unit 145, and an additional important item. It functions as the recommendation unit 146 and the like. The priority item obvious superiority horse specifying unit 144 is an example of the second race target specifying means in the present invention. The additional importance item recommendation unit 146 is an example of an item specifying unit and an item presentation control unit in the present invention.

  The important item obvious superior horse specifying unit 144 has a significant difference in the superiority and inferiority in the important items between the relatively dominant starter horse and the relatively inferior starter horse specified as the recommended horse by the selected horse recommendation unit 143. It is determined whether or not. The superiority difference is, for example, a difference in odds, a difference in race time, a difference in the number of wins, a difference in winning percentage, a difference in horse weight, a difference in superiority, and the like. Conditions for which it is recognized that the superiority difference is a significant difference may be determined in advance, for example. For example, the priority item obvious superiority horse specifying unit 144 may calculate the superiority or inferiority between the running horses having adjacent superiority or inferiority ranks. The condition that the superiority / inferiority difference is recognized to be a significant difference is that, among the calculated superiority / inferiority differences, the superiority / inferiority difference between the running horse of superiority / inferiority ranking N and the running horse of superiority / inferiority ranking N + 1 is the largest There may be.

  When the superiority or inferiority difference between the relatively dominant starter horse and the relatively inferior starter horse is not a significant difference, the priority item obvious superior horse specifying unit 144 determines that the priority item has a relatively superior starter horse. And a relatively dominant race horse with a head count that is recognized as a significant difference between superiority and inferiority between a relatively inferior race horse. The relatively dominant starter horse identified at this time is called the priority item obvious superior horse. Also, let M be the number of horses with clearly superior priority items.

  The candidate item specifying unit 145 selects items for which the superiority or inferiority between the relatively dominant starting horses and the relatively inferior starting horses is a significant difference in each item different from the priority items. Identify. This item is referred to as a candidate item for an important item to be added. A relatively dominant race horse specified in the candidate item is called a candidate item obvious superior horse.

  The additional emphasis item recommendation unit 146 has N heads that are relatively dominant among the candidate items among the identified candidate items among the emphasis item obvious superior horses identified by the emphasis item obvious superior horse identification unit 144. Items that satisfy the condition that the superiority or inferiority between the relatively inferior race horse and the relatively inferior race horse is recognized as a significant difference, and among the run horses other than the priority item obvious dominant horse, N and the priority item are obvious At least one of the items satisfying the condition that the superiority or inferiority between the relatively dominant starting horses and the relatively inferior starting horses corresponding to the difference with the number of dominant horses is recognized as a significant difference. Is identified. For example, the additional importance item recommendation unit 146 includes, among the identified candidate items, items in which all candidate item obvious dominant horses are included in the important item obvious dominant horses, or candidate item obvious dominant horses are important item obvious dominant horses. Items including all may be specified from the candidate items as recommended items. The number M of the priority item obvious dominant horses is different from the number N of the complementary item obvious dominant horses. Therefore, when the number M is larger than N, the additional importance item recommendation unit 146 identifies items in which all candidate item obvious superior horses are included in the important item obvious superior horses. On the other hand, when the number M is smaller than N, the additional importance item recommendation unit 146 identifies items in which the candidate item obvious superior horse includes all of the important item obvious superior horses. In other words, the additional importance item recommendation unit 146 specifies an item in which one of the importance item obvious superior horse and the candidate item obvious superior horse includes all of the other.

  When the number M of the priority item obvious dominant horses is larger than the number N of the recommended horses, any M-N running horses among the priority item obvious dominant horses are not originally suitable as recommended horses. In this case, the additional priority item recommendation unit 146 selects the relatively dominant N priority item obvious superior horses among the identified important item obvious superior horses and the relatively inferior MN head important item obvious superior horses. Items that are markedly different from each other are identified from the candidate items. By considering the identified item and the current priority item, the user can select N horses that are clearly superior. On the other hand, when the number M of the priority item obvious superior horses is smaller than the number N of recommended horses, all the important item obvious dominant horses are suitable as recommended horses. However, there are not enough NM recommended horses. In this case, there are NM running horses that may become recommended horses among the running horses other than the priority dominant horses. In this case, the additional importance item recommendation unit 146 is relatively dominant including all the identified M important item obvious dominant horses and the starting horses other than the important item obvious superior horses including NM heading horses. An item having a significant difference between superiority and inferiority between the N dominant item obvious obvious horses and other starting horses is identified from the candidate items. By considering the identified item and the current priority item, the user can select N horses that are clearly superior.

  A specific example will be described below. For example, it is assumed that N is 3, and the current priority item is race time (1700 meter light-track). Further, in the first race on a certain day, in the race time (1700 m light-track), the superiority and inferiority rank are higher in the order of horse numbers 1, 2, 3, 4, 5, 6

  FIG. 13 (a) is a diagram showing an example of past race times (1700 m light-track) of each running horse in the first race, and FIG. 13 (b) shows the number of wins of each running horse in the first race. It is a figure which shows an example. As shown in FIG. 13 (a), the difference in the race time between the running horse of the horse number 3 having the superiority / inferiority ranking 3rd and the running horse of the horse number 4 having the superiority / inferiority ranking 4th is small. On the other hand, the difference in the race time between the horse No. 4 running horse and the horse No. 5 running horse whose superiority ranking is fifth is remarkable. Therefore, M is 4, and the priority item obvious dominant horse is a running horse of horse numbers 1-4. In this case, the candidate item specifying unit 145 specifies, as candidate items, items for which the superiority or inferiority difference between the relatively dominant three running horses and the relatively inferior starting horse is a significant difference. . And the additional importance item recommendation part 146 identifies the item whose 3 start horses are start horses (candidate item clear dominant horse) among the start horses of horse numbers 1-4 from candidate items. To do. As shown in FIG. 13 (b), in the number of wins, the difference in the number of wins is significant between the running horse with the superiority / inferiority rank of 3rd and the running horse with the superiority / inferiority rank of 4th. The race horses that are relatively dominant in the number of wins are race horses of horse numbers 2, 1, and 4. All of these racehorses are clearly dominant horses. Therefore, the additional importance item recommendation unit 146 identifies the number of wins as a recommended item.

  When the recommended item is specified, the additional importance item recommendation unit 146 causes the user terminal 3 to present the recommended item to the user. For example, the additional importance item recommendation unit 146 causes the user terminal 3 to display recommended item information including a racetrack name, a race number, a race date, a recommended item name, and the like of the target race on the screen. FIG. 13C is a diagram illustrating a screen display example of recommended item information. For example, a message such as “How about adding the number of wins to the item to be emphasized?” Is displayed on the screen of the user terminal 3. When the recommended item is presented by the user terminal 3, the user can additionally designate the recommended item as an important item. For example, the user terminal 3 may display the recommended item information in a pop-up, or may display the recommended item information on a web page indicating completion of registration of the important item. Further, for example, the additional importance item recommendation unit 146 may present the recommended item when the selected horse recommendation unit 143 specifies the recommended horse, or presents the recommended item at a predetermined timing after the recommended horse is specified. You may let them. For example, when the user browses a web page related to a certain race, the selected horse recommendation unit 143 may present recommended items specified for the race.

  FIG.13 (d) is a figure which shows the example of the past race time (1700-meter light stadium) of each run horse in the 1st race, and FIG.13 (e) is an example of the winning rate of each run horse in the 1st race. FIG. As shown in FIG. 13 (d), the difference in race time between the running horse of the horse number 3 having the superiority / inferiority ranking 3rd and the running horse of the horse number 4 having the superiority / inferiority ranking 4th is small. On the other hand, the difference in the race time between the horse No. 1 running horse whose superiority / inferiority rank is first and the horse No. 2 running horse whose superiority / inferiority rank is second is remarkable. Therefore, M is 1, and the priority item obvious dominant horse is the horse of horse number 1. Also in this case, the candidate item specifying unit 145 specifies, as candidate items, items for which the superiority or inferiority difference between the relatively dominant three running horses and the relatively inferior starting horse is a significant difference. To do. Then, the additional importance item recommendation unit 146 identifies, from among the candidate items, an item in which the starting horse of horse number 1 is a relatively starting horse (candidate item obvious dominant horse). As shown in FIG. 13 (e), in the winning rate, the difference in the number of wins is significant between the running horse with the superiority / inferiority ranking third and the running horse with the superiority / inferiority ranking fourth. The race horses that are relatively dominant in winning percentage are the race horses of horse numbers 5, 1 and 3. These starting horses include all of the priority items clearly dominant horses (running horse of horse number 1). Therefore, the additional importance item recommendation unit 146 identifies the winning percentage as the recommended item.

  In the description so far, the condition of the candidate item is that the superiority or inferiority difference between the relatively dominant starting horses with N heads is a significant difference. However, the candidate item specifying unit 145 may determine whether the superiority or inferiority rank is adjacent even if the superiority or inferiority difference between the relatively dominant starter horses with N heads is not a significant difference. If the item has a significant difference in superiority or inferiority between the running horses, the item may be specified as a candidate item. When the number of heads M is greater than the number of heads N, it is only necessary to identify N running horses that are clearly superior among the horses with clearly superior priority items. Therefore, in the candidate items, the additional importance item recommendation unit 146 performs superiority or inferiority between N relatively important priority item obvious superior horses and relatively inferior important item obvious dominant horses among the important item obvious superior horses. Candidate items that are significantly different are identified as recommended items. When there are N candidate item obvious dominant horses of a candidate item, the additional important item recommendation unit 146 results in that candidate item when all candidate item obvious dominant horses are included in the important item obvious dominant horse. Is specified as the recommended item. On the other hand, when M is smaller than the number N of recommended horses, it is only necessary to identify clearly running NM head horses from among the other horses other than the priority item obvious dominant horses. This is because, when the runners identified as the priority items clearly dominant horses are combined, N horses will be relatively dominant. Therefore, the additional importance item recommendation unit 146 has a remarkable superiority / inferiority difference between a relatively dominant starter horse and a relatively inferior starter horse among the starter horses other than the important priority item clearly superior horses. A candidate item that is a large difference is identified as a recommended item. At this time, the important item obvious dominant horse may or may not be included in the candidate item obvious dominant horse in the candidate item. Even if the priority item obvious dominant horse is not included in the candidate item obvious dominant horse in the candidate item, it can be considered that it is already determined as a running horse with a probability of being selected by the current priority item. When the candidate item obvious dominant horse of a candidate item has N heads, the additional important item recommendation unit 146 results in the candidate item being displayed when the candidate item obvious dominant horse includes all of the important item obvious dominant horses. It will be specified as a recommended item.

  A specific example will be described below. For example, as in the example of FIG. 13, N is 3, and the current priority item is race time (1700 meters light-track). It is assumed that the past race time (1700 m lightning course) of each running horse in the first race is as shown in FIG. FIG. 14A is a diagram illustrating an example of the number of wins of each running horse in the first race. As shown in FIG. 14 (a), in the number of wins, the difference in the number of wins is significant between the running horse with the superiority / inferiority rank of 4th and the running horse with the superiority / inferiority rank of 5th. In addition, the running horses having the superiority or inferiority rank in the number of wins are 4 or more are the running horses of horse numbers 2, 1, 4, and 6. Among these race horses, the horses with the obvious priority items are the race horses with horse numbers 2, 1, and 4, and the respective superiority and inferiority rankings are first, second, and third. The superiority of the remaining horse, horse number 3, which is clearly the dominant horse, is fifth. Therefore, there are three priority item obvious superior horses included in the candidate item obvious dominant horses. Also, since the difference in the number of wins between the horses running from horse number 6 and the horses running from horse number 3 is significant, the difference in the number of wins between the horses running from horse number 4 and the horses running from horse number 3 is also significant. . Therefore, the additional importance item recommendation unit 146 identifies the winning percentage as the recommended item. The racehorses of horse numbers 2, 1 and 4 are the racehorses that are likely to be selected as racehorses that are relatively dominant, assuming that race time (1700m light stadium) and a small number are the priority items. is there.

  In addition, it is assumed that the past race time (1700 meter light horse race) of each running horse in the first race is as shown in FIG. FIG. 14B is a diagram showing an example of the winning percentage of each running horse in the first race. As shown in FIG. 14 (b), in the winning rate, the difference in the number of wins is significant between the running horse with the superiority / inferiority ranking second and the running horse with the superiority / inferiority ranking third. In addition, the running horses with the winning / inferiority ranking of 2nd or higher are the running horses of horse numbers 5 and 3, and the running horse of horse number 1 which is the dominant horse with obvious priority items is the 4th place. Accordingly, there are two runners included in the candidate item obvious superior horses except the important item obvious dominant horses. If you add the number of horses with clearly dominant priority items to these two, you get three. Therefore, the additional importance item recommendation unit 146 identifies the winning percentage as the recommended item. Race horses with horse numbers 1, 5, and 3 are race horses that are likely to be selected as race horses that are relatively dominant, assuming that race time (1700m light stadium) and win rate are both important items. is there.

  In addition, the selection horse recommendation part 143 may identify a recommendation horse based on a superiority like 2nd Embodiment. In this case, the priority item obvious dominant horse specifying unit 144 may determine whether the difference in superiority is a significant difference.

  Further, for example, a minimum value of superiority or inferiority recognized as a significant difference may be determined in advance for each important item. In this case, the priority item obvious superiority horse specifying unit 144 determines whether the superiority or inferiority difference between the N-ranked running horse and the N + 1-ranking running horse specified as the recommended horse is equal to or greater than a predetermined minimum value. The superiority / inferiority rank M where the superiority / inferiority difference with the racehorse having one lower superiority / inferiority rank is equal to or greater than a predetermined minimum value may be specified. Further, the candidate item specifying unit 145 may specify a candidate item in which the superiority / inferiority difference between the N-ranked running horse and the N + 1-ranked running horse is equal to or greater than a predetermined minimum value.

[3-2. Operation of information processing system]
Next, the operation of the information processing system S will be described with reference to FIGS. FIG. 15 is a flowchart illustrating a processing example of the race-oriented important item registration processing by the system control unit 14 of the betting ticket release agency server 1 according to the present embodiment. In FIG. 15, processes similar to those in FIG. 6 are denoted by the same reference numerals.

  As shown in FIG. 15, steps S1 to S4 are first executed. In the recommended horse specifying process in step S3, the selected horse recommendation unit 143 specifies N recommended horses. After step S4, the important item obvious superiority horse specifying unit 144 calculates the superiority or inferiority between the running horses having adjacent superiority or inferiority in the priority item of the designated race (step S6). Next, the priority item obvious superiority horse specifying unit 144 determines whether the superiority or inferiority difference between the N-ranked running horse and the N + 1-running horse among the calculated superiority difference is the largest. (Step S7). At this time, when the priority item obvious superior horse specifying unit 144 determines that the superiority / inferiority difference between the Nth place horse and the N + 1 place horse is the largest (step S7: YES), the process proceeds to step S5. move on.

  On the other hand, if the priority item obvious superior horse specifying unit 144 determines that the superiority or inferiority difference between the Nth place horse and the N + 1 place horse is not the maximum (step S7: NO), the process proceeds to step S8. . In step S8, the additional importance item recommendation unit 146 executes a recommended item specifying process. In the recommended item specifying process, the additional importance item recommending unit 146 specifies recommended items and generates recommended item information. Details of the recommended item specifying process will be described later. Next, the additional importance item recommendation unit 146 adds the generated recommended item information to the recommended horse information (step S9).

  Next, the selected horse recommendation unit 143 transmits recommended horse information to the user terminal 3 (step S5). When step S5 is completed, the selected horse recommendation unit 143 ends the race-specific importance item registration process. The user terminal 3 that has received the recommended horse information displays the recommended horse information on the screen. When the recommended item information is added to the recommended horse information, the user terminal 3 displays the recommended item information together with the recommended horse information.

  FIG. 16 is a flowchart illustrating a processing example of the recommended item specifying process by the system control unit 14 of the betting ticket release agency server 1 according to the present embodiment. As shown in FIG. 16, the priority item obvious superiority horse specifying unit 144 has the highest priority difference M of the starting horse with the highest priority difference between the starting horse and the lowering priority in the priority item of the recommended race. Is identified. Further, the important item obvious superiority horse specifying unit 144 specifies a running horse whose superiority or inferiority rank is M or higher as an important item obvious superiority horse (step S51). Next, the racehorse information acquisition unit 142 acquires information about a plurality of racehorses corresponding to the race ID of the recommendation target race (step S52). Specifically, the racehorse information acquisition unit 142 acquires racehorse information corresponding to the race ID of the recommended race from the race information DB 12b. Moreover, the running horse information acquisition part 142 acquires the winning odds of each running horse out of the odds corresponding to the race ID of the recommended race from the odds information DB 12d.

  Next, the candidate item specifying unit 145 determines, for each item other than the priority item, the superiority or inferiority ranking of each running horse in the recommended race in that item (step S53). Next, the candidate item specifying unit 145 calculates the superiority or inferiority between the running horses whose superiority and inferiority ranks are adjacent in each item (step S54). Next, the candidate item specifying unit 145 selects an item in which the superiority / inferiority difference between the N-ranked horse and the N + 1-ranked horse among the calculated superiority / inferiority is the largest among the items other than the priority items. Specify as a candidate item. Further, the candidate item specifying unit 145 specifies the starting horse whose superiority / inferiority rank is N in the candidate item as a candidate item obvious dominant horse (step S55).

  Next, the additional importance item recommendation unit 146 determines whether M is greater than N (step S56). At this time, if the additional importance item recommendation unit 146 determines that M is greater than N (step S56: YES), the process proceeds to step S57. In step S57, the additional importance item recommendation unit 146 determines, among the candidate items, an item in which all candidate item obvious superior horses are included in the important item obvious superior horse as recommended items. Next, the additional importance item recommendation unit 146 proceeds to step S59. On the other hand, if the additional importance item recommendation unit 146 determines that M is not greater than N (step S56: NO), the process proceeds to step S58. In step S58, the additional importance item recommendation unit 146 determines, among the candidate items, items whose candidate item obvious superior horses include all of the important item obvious superior horses as recommended items. Next, the additional importance item recommendation unit 146 proceeds to step S59.

  In step S59, the additional importance item recommendation unit 146 generates recommended item information based on the item ID of the recommended item, the race ID of the recommendation target race, and the like. When step S59 is completed, the additional importance item recommendation unit 146 ends the recommended item specifying process.

  FIG. 17 is a flowchart showing a processing example of a multi-race selection horse recommendation process by the system control unit 14 of the betting ticket release agency server 1 according to the present embodiment. In FIG. 17, processes similar to those in FIG. 9 are given the same reference numerals. As shown in FIG. 17, steps S31 to S35 are first executed. Next, the important item obvious superiority horse specifying unit 144 calculates the superiority or inferiority difference between the running horses in which the superiority and inferiority ranks are adjacent in the user importance item (step S61). Next, the priority item obvious superiority horse specifying unit 144 determines whether the superiority or inferiority difference between the N-ranked running horse and the N + 1-running horse among the calculated superiority difference is the largest. (Step S62). At this time, if the priority item obvious superiority horse specifying unit 144 determines that the superiority or inferiority difference between the Nth place horse and the N + 1 place horse is the largest (step S62: YES), the process proceeds to step S36. move on.

  On the other hand, if the priority item obvious superior horse specifying unit 144 determines that the superiority or inferiority difference between the Nth place horse and the N + 1 place horse is not the maximum (step S62: NO), the process proceeds to step S63. . In step S63, the additional importance item recommendation unit 146 executes a recommended item specifying process. In the recommended item identification process, the additional importance item recommendation unit 146 identifies the recommended item of the race indicated by the selected race ID from items other than the user importance item, and then the additional importance item recommendation unit 146 is generated. The recommended item information is added to the recommended horse information (step S64). Next, the selected horse recommendation unit 143 executes steps S36 to S38, and ends the race-specific importance item registration process. The user terminal 3 displays each recommended horse information received from the betting ticket sale agency server 1 on the screen. When the recommended item information is added to the recommended horse information, the user terminal 3 displays the recommended item information together with the recommended horse information.

  As described above, according to the present embodiment, the system control unit 14 specifies the relatively dominant starting horses for N heads set in advance as recommended horses. When the system control unit 14 does not satisfy the condition that the superiority or inferiority difference between the recommended horse and the starting horse not identified as the recommended horse is a significant difference, Identifies relatively dominant priority items clearly dominant horses for M heads that satisfy the condition that the superiority or inferiority difference between at least one of the plurality of starting horses is recognized as a significant difference . In addition, the system control unit 14 includes a plurality of candidate items that are different from the priority item, and a relatively dominant starter horse and a relatively inferior starter horse of the N priority items among the priority item obvious dominant horses. Equivalent to the difference between N and the number of heads of obvious priority horses in the candidate items among the items that satisfy the condition that the superiority or inferiority difference between them is recognized as a significant difference, or among the running horses other than the horses with obvious dominant horses The items satisfying the condition that the superiority / inferiority difference between the relatively dominant race horses and the relatively inferior race horses corresponding to the number of horses to be recognized are marked differences are identified. Then, the system control unit 14 presents the identified item. Therefore, the user can know an item that is preferably added to an item that is important for selecting a running horse.

[4. Fourth Embodiment]
[4-1. Details of system control function]
Next, a fourth embodiment will be described. In the present embodiment, the selected horse recommendation unit 143 has a relative number of heads that satisfy a condition in which a superiority or inferiority difference between a relatively dominant starter horse and a relatively inferior starter horse is recognized as a significant difference. The dominant running horse is identified as the recommended horse. The user who has received the recommended horse can select a predicted running horse from among the running horses clearly superior to other running horses. The conditions under which the superiority difference is recognized to be a significant difference are the same as in the case of the third embodiment. In other respects, the present embodiment is the same as the first embodiment or the second embodiment.

  A specific example will be described below. FIG. 18 is a diagram illustrating an example of a past race time (1700 meter light racetrack) of a running horse participating in a certain race. For example, the past race times (1700m light stadium) for horses 5, 6, 2, 1, 4, and 3 are 1 minute 40.0 seconds, 1 minute 40.3 seconds, 1 minute 40.5, respectively. Second, 1 minute 41.0 seconds, 1 minute 44.2 seconds, 1 minute 44.9 seconds. In this case, the difference in race time between horses 5 and 6 is 0.3 seconds, the difference in race time between horses 6 and 2 is 0.2 seconds, and the race time between horses 2 and 1 The difference in race time between horses 1 and 4 is 3.2 seconds, and the race time between horses 4 and 3 is 0.7 seconds. Therefore, the difference between the race time of the horse number 1 and the race time of the horse number 4 is the largest. Therefore, the selected horse recommendation unit 143 identifies the running horses with horse numbers 5, 6, 2, and 1 as relatively competitive horses, that is, recommended horses. When specifying a recommended horse using a plurality of priority items, the selection horse recommendation unit 143 has a significant difference between a relatively dominant starter horse and a relatively inferior starter horse for each priority item. A certain number of relatively dominant horses may be identified. In other words, the selected horse recommendation unit 143 may separate a relatively dominant starter horse and a relatively inferior starter horse among starter horses that have a significant difference in superiority or inferiority among adjacent starter horses. Good. Then, the selected horse recommendation unit 143 may specify a running horse included in a relatively dominant running horse as a recommended horse in all of the plurality of important items. Alternatively, the selected horse recommendation unit 143 calculates the superiority as in the second embodiment, for example, and calculates the superiority between the starting horse with a relatively high priority and the starting horse with a relatively low priority. A running horse with a relatively high degree of superiority in the number of heads, where the difference is significant, may be specified as a recommended horse.

[4-2. Operation of information processing system]
Next, the operation of the information processing system S will be described with reference to FIG. FIG. 19 is a flowchart showing a processing example of recommended horse specifying processing by the system control unit 14 of the betting ticket release agency server 1 according to the present embodiment. In FIG. 19, the same processes as those in FIG. As shown in FIG. 19, steps S11 and S12 are first executed. Next, the selected horse recommendation unit 143 calculates a superiority / inferiority difference between runners having adjacent superiority or inferiority ranks in the priority items of the race to be recommended (step S71). Next, the selected horse recommendation unit 143 specifies the superiority / inferiority rank M of the running horse that maximizes the superiority / inferiority difference with the running horse having a lower superiority / inferiority rank in the priority item (step S72). Next, the selected horse recommendation unit 143 determines a running horse whose superiority / inferiority rank is M or higher as a recommended horse (step S73). Next, the selected horse recommendation unit 143 generates recommended horse specifying information (step S14), and ends the recommended horse specifying process.

  As described above, according to the present embodiment, the system control unit 14 recognizes that the superiority or inferiority difference between the relatively dominant starter horse and the relatively inferior starter horse is a significant difference. A relatively dominant racehorse satisfying several minutes is identified as a recommended horse. Therefore, the user can know a clearly superior starting horse as compared to a relatively inferior starting horse.

[5. Fifth Embodiment]
[5-1. Details of system control function]
Next, a fifth embodiment will be described. When it is not possible to clearly separate a relatively dominant starter horse identified as a recommended horse and a relatively inferior starter horse, there is a possibility that the selection criteria for the recommended horse are ambiguous. Therefore, in the present embodiment, the selected horse recommendation unit 143 does not present recommended horses for races that do not satisfy the condition that the superiority or inferiority between the recommended horses and other running horses is recognized as a significant difference. The conditions under which the superiority difference is recognized to be a significant difference are the same as in the case of the third embodiment. In other respects, this embodiment is the same as the first to third embodiments. As in the third embodiment, for the race where the superiority or inferiority between the recommended horse and other starting horses is not a significant difference, the additional importance item recommendation unit 146 adds the importance that is added instead of the recommended horse being presented. An item recommended as an item may be presented.

  For example, it is assumed that the priority item is a race time (1700 m light-track), and the selected horse recommendation unit 143 specifies three recommended horses. For example, as shown in FIGS. 13 (a) and 13 (d), the difference in the race time between a running horse with the superiority / inferiority ranking third and a running horse with the superiority / inferiority ranking fourth is small. In this case, the selected horse recommendation unit 143 does not transmit the recommended horse information to the user terminal 3. Alternatively, for example, the minimum value of the superiority or inferiority that is determined to be a significant difference may be determined in advance for each priority item. In this case, the selected horse recommendation unit 143 does not transmit the recommended horse information to the user terminal 3 when, for example, all of the superiority or inferiority difference between the running horses having adjacent superiority and inferiority ranks is less than a predetermined minimum value.

  In addition, the selection horse recommendation part 143 may identify a recommendation horse based on a superiority like 2nd Embodiment. In this case, the selected horse recommendation unit 143 may not present the recommended horse when the difference in the superiority between the recommended horse and the other running horses is not a significant difference.

  Moreover, the selection horse recommendation part 143 satisfy | fills the conditions recognized that the superiority / inferiority difference between a comparatively superior starter horse and a relatively inferior starter horse is a remarkable difference like 3rd Embodiment. For races that identify a racehorse with a relatively large number of horses as the recommended horse, but do not meet the conditions for which the superiority or inferiority between the recommended horse and other racehorses is recognized as a significant difference, It is not necessary to present. The first condition is a condition that is used when identifying a relatively dominant recommended horse, and the superiority or inferiority difference is recognized as a significant difference. A condition that is recognized as a significant difference is defined as a second condition. For example, the first condition and the second condition may be different. In this case, the selected horse recommendation unit 143 identifies the recommended horses having the number of horses satisfying the first condition, for example, the superiority or inferiority between the relatively dominant starting horse and the relatively inferior starting horse for each race to be recommended To do. And the selection horse recommendation part 143 shows a recommendation horse only about the race in which the superiority / inferiority difference between a recommendation horse and other run horses satisfy | fills a 2nd condition among the races of recommendation object, and a superiority / inferiority difference is 2nd condition. No recommendation horse will be presented for races that do not meet.

[5-2. Operation of information processing system]
Next, the operation of the information processing system S will be described with reference to FIG. FIG. 20 is a flowchart showing a processing example of a multi-race selection horse recommendation process by the system control unit 14 of the betting ticket release agency server 1 according to the present embodiment. In FIG. 20, processes similar to those in FIG. 9 are given the same reference numerals. As shown in FIG. 20, steps S31 to S34 are first executed. Next, the selected horse recommendation unit 143 calculates the superiority or inferiority between the running horses whose superiority and inferiority ranks are adjacent in the user-oriented items for the race indicated by the selected race ID (step S81). Next, the selected horse recommendation unit 143 determines whether the superiority or inferiority difference between the running horse with the superiority / inferiority ranking of the Nth place and the running horse of the N + 1st place is the maximum among the calculated superiority / inferiority differences (step S82). ). At this time, if the selected horse recommendation unit 143 determines that the superiority or inferiority difference between the Nth place running horse and the N + 1 place running horse is not the maximum (step S82: NO), the process proceeds to step S36.

  On the other hand, if the selected horse recommendation unit 143 determines that the superiority or inferiority difference between the N-th running horse and the N + 1-th running horse is the maximum (step S82: YES), the process proceeds to step S35. In step S35, the selected horse recommendation unit 143 registers the recommended horse specifying information generated in the recommended horse specifying process in the race-specific important item information DB 12e in association with the selected race ID and the user ID of the user to be recommended. To do. Next, the selected horse recommendation unit 143 executes steps S36 to S38, and ends the race-specific importance item registration process. In step S38, the selected horse recommendation unit 143 transmits the recommended horse information only for the recommended horse specifying information registered in the important item information DB 12e by race in step S35 among the recommended horse specifying information generated in the recommended horse specifying process. To do.

  In addition, in the priority item registration process for each race, if the superiority or inferiority difference between the recommended horse and the other running horses is not a significant difference for the designated race, the selected horse recommendation unit 143 may present the recommended horse. , It does not have to be presented.

  As described above, according to the present embodiment, the system control unit 14 recognizes that the superiority or inferiority difference between the specified recommended horse and the starting horse not specified as the recommended horse is a significant difference. If the superiority or inferiority condition is not satisfied, the recommended horse is not presented. Therefore, the betting ticket release agency server 1 prevents the number of horses that are not necessarily valid from being presented due to the vague boundary between the relatively dominant horse and the relatively inferior horse. be able to.

[6. Sixth Embodiment]
Next, a sixth embodiment will be described. In the present embodiment, the betting ticket release agency server 1 limits the race in which the recommended horse is presented based on the purchase record of the user's betting ticket. Even if the recommended horse is presented, the user may not purchase a betting ticket or may select a starting horse different from the recommended horse and purchase a betting ticket. Whether or not a user purchases a betting ticket may be attributed to the superiority or inferiority of a plurality of running horses participating in a race, for example. For example, there may be a user who tends to purchase a betting ticket for a race with a great favorite, or a user who tends to purchase a betting ticket for a race that is expected to have a melee battle. Therefore, the betting ticket release agency server 1 causes the recommended horse to be presented only for a race in which the superiority or inferiority of the running horse matches the situation of the race in which the user selects the recommended horse and purchases the betting ticket. In other points, the present embodiment is the same as the first to fifth embodiments.

  FIG. 21 is a sequence diagram illustrating an operation example of the information processing system S according to the present embodiment. For example, the betting ticket release agency server 1 specifies a recommended horse for a race R1-1 on a certain day, and transmits recommended horse information to the user terminal 3 (step S91). After the user terminal 3 displays the recommended horse information, the user performs an operation of purchasing a betting ticket for the race R1-1 (step S92). At this time, it is assumed that the user selects a purchase with reference to the recommended horse information. Then, the user terminal 3 transmits a purchase request to the betting ticket sale agency server 1 (step S93). The purchase request includes the race ID of the designated race and the purchase eye information indicating the selected purchase eye. The betting ticket sales agency server 1 that has received the purchase request registers the betting ticket purchase history in the betting ticket purchase history DB 12h (step S94). At this time, the betting ticket release agency server 1 transmits the race ID and purchase information included in the purchase request, recommended horse specifying information indicating the recommended horse specified by the betting ticket release agency server 1 for the race R1-1, and the user who transmitted the purchase request. The user ID of the user who uses the terminal 3 is stored in the betting ticket purchase history. As a result, the purchase information and the recommended horse specifying information are stored in the storage unit 12 in association with each other.

  Thereafter, the betting ticket release agency server 1 executes the user-oriented item specifying process at a predetermined timing. At this time, the betting ticket release agency server 1 selects, based on the betting ticket purchase history, a race in which the racehorse indicated by the purchase information matches the racehorse indicated by the recommended horse specifying information among the past races where the betting ticket has been purchased. Extract (step S95). Next, the betting ticket sale agency server 1 identifies relatively important items as important items among the extracted important items in the past race (step S96).

  Thereafter, the betting ticket release agency server 1 executes a multiple race selection horse recommendation process at a predetermined timing. At this time, the betting ticket sale agency server 1 specifies a race in which the superiority / inferiority status of the running horse in the user-focused item matches the superiority / inferiority status of the running horse in the past race extracted in step S95 (step S97). Next, the betting ticket release agency server 1 specifies a recommended horse only for the specified race (step S98) and transmits recommended horse information to the user terminal 3 (step S99).

[6-1. Details of system control function]
Next, the functional outline of the system control unit 14 of the betting ticket release agency server 1 will be described with reference to FIGS. 22 and 23. FIG. 22 is a diagram illustrating an example of functional blocks of the system control unit 14 of the betting ticket release agency server 1 according to the present embodiment. As shown in FIG. 22, the system control unit 14 functions as an important item acquisition unit 141, a running horse information acquisition unit 142, a selected horse recommendation unit 143, a betting ticket purchase history registration unit 147, a recommendation target race identification unit 148, and the like. The betting ticket purchase history registration unit 147 is an example of a storage control unit in the present invention. The recommended race specifying unit 148 is an example of a race specifying unit in the present invention.

  The betting ticket purchase history registration unit 147 stores the betting ticket purchase history in the storage unit 12. Specifically, the betting ticket purchase history registration unit 147 acquires the purchase request transmitted from the user terminal 3 via the communication unit 11. Next, the betting ticket purchase history registration unit 147 acquires a race ID and purchase information from the purchase request. Further, the betting ticket purchase history registration unit 147 acquires the user ID of the user who uses the user terminal 3 that has transmitted the purchase request, based on the session ID, for example. Further, the recommended horse specifying information registered in the race-specific important item information DB 12e in association with the acquired race ID and user ID is acquired. Next, the betting ticket purchase history registration unit 147 generates a betting ticket purchase history including the acquired race ID, user ID, purchase information, and recommended horse specifying information. Then, the betting ticket purchase history registration unit 147 registers the betting ticket purchase history in the betting ticket purchase history DB 12h.

  The priority item acquisition unit 141 is based on the purchase information and recommended horse identification information included in the betting ticket purchase history registered in the betting ticket purchase history DB 12h. The races that match are extracted. At this time, for example, the emphasis item acquisition unit 141 may extract a race in which the racehorse indicated by the purchase information and the racehorse indicated by the recommended horse identification information partially match, or only races in which all match. It may be extracted. Next, the priority item acquisition unit 141 acquires relatively important priority items as user priority items based on the extracted priority item information of the past race. Next, the betting ticket purchase history registration unit 147 specifies the superiority or inferiority of the running horse in the user-oriented items for the extracted race. For example, the betting ticket purchase history registration unit 147 specifies the number of relatively dominant starting horses that have a significant difference in superiority or inferiority between a relatively dominant starting horse and a relatively inferior starting horse. This number is called the past dominant number. The conditions under which the superiority difference is recognized to be a significant difference are the same as in the case of the third embodiment. The smaller the number of dominant horses, the limited the number of horses that are expected to win in the higher ranks.

  The recommendation target race specifying unit 148 specifies a race in which the superiority or inferiority of the running horse matches the superiority or inferiority of the running horse in the past race. Races that are candidates for the race to be identified are races for which the sale of betting tickets has not yet been closed. For example, the candidate race may be a race scheduled to be held today. The recommendation target race specifying unit 148 specifies the superiority or inferiority of the running horse in the user-oriented items for each candidate race. For example, the recommendation target race specifying unit 148 specifies the number of heads of relatively dominant race horses that have a significant difference between superiority and inferiority of relatively dominant race horses and relatively inferior race horses. Then, the recommendation target race specifying unit 148 specifies a race in which the specified number of heads matches the number of past dominant heads. The selected horse recommendation unit 143 presents the recommended horse of the specified race.

  A specific example will be described below. FIG. 23A is a diagram showing a past race time (1700 meters, light horse race) of a running horse of the first race held on December 1st. For example, the priority item of the first race on December 1 is the race time (1700 meters, light racetrack), and the selection horse recommendation unit 143 has the recommended horses presented based on the race time (1700 meters, light racetrack). . The user selects a recommended horse and purchases a betting ticket. As shown in FIG. 23 (a), the difference in race time between the racehorse with the superiority / inferiority rank of 2nd and the racehorse with the superiority / inferiority rank of 3rd is remarkable. The priority item acquisition unit 141 determines, for example, the race time (1700 meters, light horse riding) as the user priority item and determines the past dominant number to two. FIG. 23B is a diagram showing a past race time (1700 meters, light horse race) of a running horse of the first race scheduled to be held on December 2nd. As shown in FIG. 23 (b), the difference in the race time between the running horse whose superiority / inferiority rank is 5th and the running horse whose superiority / inferiority rank is 6th is remarkable. Therefore, there are clearly five relatively dominant horses. Therefore, the selected horse recommendation unit 143 does not present a recommended horse for the first race on December 2. FIG. 23 (c) is a diagram showing the past race time (1700 meters, light racetrack) of the horses running in the second race scheduled to be held on December 2nd. As shown in FIG. 23 (c), the difference in the race time between the running horse whose superiority / inferiority rank is 2nd and the running horse whose superiority / inferiority rank is 3rd is remarkable. Therefore, there are clearly two relatively dominant horses. Accordingly, the selected horse recommendation unit 143 presents recommended horses for the second race on December 2nd.

[6-2. Operation of information processing system]
Next, the operation of the information processing system S will be described with reference to FIGS. FIG. 24 is a flowchart illustrating a processing example of user-oriented item registration processing by the system control unit 14 of the betting ticket release agency server 1 according to the present embodiment. In FIG. 24, the same symbols are attached to the same processes as those in FIG. As illustrated in FIG. 24, the important item acquisition unit 141 acquires a user ID of a user who is a registration target of the user important item (step S21). Next, the important item acquisition unit 141 searches the betting ticket purchase history DB 12h for the betting ticket purchase history corresponding to the acquired user ID (step S101). At this time, the emphasis item acquisition unit 141 searches for all the emphasis item information of a race held for a predetermined period, for example. Next, the priority item acquisition unit 141 compares the horse number included in the purchase information included in the betting ticket purchase history with the horse number included in the recommended horse specifying information for each searched betting ticket purchase history. Then, the important item acquisition unit 141 extracts the betting ticket purchase history in which the horse number included in the purchase information matches the horse number included in the recommended horse specifying information (step S102). When the purchase number information includes a frame number, the priority item acquisition unit 141 acquires a horse number corresponding to the frame number based on the race information DB 12b, for example. Then, the priority item acquisition unit 141 compares the acquired horse number with the horse number included in the recommended horse specifying information.

  Next, the important item acquisition unit 141 acquires a race ID from the betting ticket purchase history for each extracted betting ticket purchase history (step S103). Then, the priority item acquisition unit 141 acquires priority item information corresponding to the acquired race ID and the user ID of the recommendation target user from the priority item information DB 12e by race (step S104). Next, the important item acquisition unit 141 calculates the number of designated important items for each item based on the item ID included in the acquired important item information (step S23). Then, the emphasis item acquisition unit 141 determines one or more items with a relatively large number of designated times as user emphasis items (step S24).

  Next, the priority item acquisition unit 141 selects one of the race IDs acquired in step S103 (step S105). Next, the emphasis item acquisition unit 141 acquires information corresponding to the user emphasis item among the information of the plurality of running horses corresponding to the selected race ID (step S106). Next, based on the information acquired by the racehorse information acquisition unit 142, the priority item acquisition unit 141 determines the superiority or inferiority ranking of each racehorse of the race indicated by the selected race ID in the user priority item (step S107). . Next, the priority item acquisition unit 141 calculates the superiority / inferiority difference between the running horses having adjacent superiority or inferiority ranks (step S108). Next, the priority item acquisition unit 141 specifies the superiority / inferiority ranking of the racehorse that maximizes the superiority / inferiority difference with the racehorse having the lowest superiority / inferiority ranking (step S109).

  Next, the priority item acquisition unit 141 determines whether there is a race ID that has not yet been selected in the acquired race ID (step S110). At this time, if the priority item acquisition unit 141 determines that there is a race ID that has not yet been selected (step S110: YES), the process proceeds to step S111. In step S111, the priority item acquisition unit 141 selects one race ID that has not yet been selected. Next, the important item acquisition unit 141 proceeds to step S106.

  On the other hand, if it is determined that all the race IDs have been selected (step S110: NO), the priority item acquisition unit 141 proceeds to step S112. In step S112, the emphasis item acquisition unit 141 determines the superiority / inferiority rank identified most among the superiority / inferiority ranks identified in step S109. Then, the priority item acquisition unit 141 determines the most dominant rank as the value of the past dominant number. Next, the priority item acquisition unit 141 registers the priority item information including the item ID of the user priority item and the past dominant number in the user priority item information DB 12f in association with the user ID acquired in Step S21 (Step S113). ). When step S113 ends, the priority item acquisition unit 141 ends the user priority item registration victory.

  FIG. 25 is a flowchart showing a processing example of a multiple race selection horse recommendation process by the system control unit 14 of the betting ticket release agency server 1 according to the present embodiment. In FIG. 25, processes similar to those in FIG. As shown in FIG. 24, steps S31 to S34 are first executed. Next, the recommendation target race specifying unit 148 acquires the past dominant number L from the priority item information acquired in step S31 (step S121). Next, the recommendation target race specifying unit 148 calculates the superiority or inferiority between the running horses whose superiority and inferiority ranks are adjacent in the user-oriented items for the race indicated by the selected race ID (step S122). Next, the recommendation target race specifying unit 148 determines whether the superiority or inferiority difference between the running horse with the superiority or inferiority ranking L and the running horse with the L + 1 ranking is the largest among the calculated superiority or inferiority (step) S123). At this time, if the selected horse recommendation unit 143 determines that the superiority or inferiority difference between the L-running horse and the L + 1-running horse is not the maximum (step S123: NO), the process proceeds to step S36.

  On the other hand, if the selected horse recommendation unit 143 determines that the superiority or inferiority difference between the L-running horse and the L + 1-running horse is the maximum (step S123: YES), the process proceeds to step S35. In step S35, the selected horse recommendation unit 143 registers the recommended horse specifying information generated in the recommended horse specifying process in the race-specific important item information DB 12e in association with the selected race ID and the user ID of the user to be recommended. To do. Next, the selected horse recommendation unit 143 executes steps S36 to S38, and ends the race-specific importance item registration process. In step S38, the selected horse recommendation unit 143 transmits the recommended horse information only for the recommended horse specifying information registered in the important item information DB 12e by race in step S35 among the recommended horse specifying information generated in the recommended horse specifying process. To do.

  As described above, according to the present embodiment, the system control unit 14 purchases information indicating the purchase of the betting ticket purchased by the user, and the recommended horse indicating the recommended horse presented for the race where the betting ticket is purchased. The specific information is stored in the storage unit 12. In addition, when the running horse indicated by the purchase information stored in the storage unit 12 matches the running horse indicated by the recommended horse specifying information, the system control unit 14 places importance on the races whose sales of betting tickets are not closed. The race in which the superiority / inferiority status of the plurality of running horses participating in the race in the item matches the superiority / inferiority status of the plurality of running horses participating in the race in which the betting ticket is purchased is specified. Then, the system control unit 14 causes the recommended horse to be presented for the identified race among the races for which sales of betting tickets are not closed. Therefore, the user can know a running horse having a probability that the user selects in a race in which the user purchases a betting ticket.
