Description

[Technical Field]

[0001] The present invention relates to an information provision method, an information provision system, and an information provision program, and relates to providing information on publicly managed races. [Background technology]

[0002] Conventionally, in publicly managed sports events such as boat racing, horse racing, bicycle racing, and auto racing, advance odds information, which can be used as a reference when placing bets, is displayed on monitors at the venue before the race. The predetermined information (race information) displayed on the monitor is usually switched based on a preset schedule. For example, odds information for a predetermined race according to multiple betting types is displayed at predetermined intervals, requiring fans to search for and confirm the desired information from the monitor display. A display device, for example, displays odds information on a monitor. For example, in the case of boat racing, a group number refers to a number or combination of numbers that can be bet (selected). In a boat race with six boats, if the betting type is win, the group numbers range from 1 to 6. In this case, the total number of group numbers is six. In addition to win, betting types include place, quinella, quinella combination, trifecta, trifecta combination, and extended combination. The display device displays the group number and the odds information corresponding to that group number.

[0003] For example, the horse racing information distribution system disclosed in Patent Document 1 includes "an information management server that obtains various types of horse racing information from a host system and creates information for screens, and an information distribution server that downloads various types of information in response to requests from terminals connected via communication lines; the information management server has a configuration file that indicates which data of the various types of horse racing information obtained from the host system is necessary for multiple style sheets that are templates for creating screens, and a data setting means that selects necessary data from the various types of horse racing information for each style sheet based on the configuration information in the configuration file; the information distribution server has a terminal application program dedicated to the terminal, the multiple style sheets used in the terminal application program, and a memory unit that stores the horse racing information selected for each style sheet by the information management server, and downloads each piece of information stored in the memory unit in response to requests from the terminal." This horse racing information distribution system also has a data editing function that allows the user to select which odds to display using the application or style sheet, and displays odds information on the terminal (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-087328 Summary of the Invention [Problem to be solved by the invention]

[0005] The horse racing information distribution system disclosed in Patent Document 1 allows users to select which odds to display on the display device.

[0019] The support rate calculation unit 16 uses the acquired odds information K tk Based on the above, the support rate S tk This is a function block that calculates the support rate S tk The calculation is based on the payout rate R of a given ticket type for a given race in a publicly managed game and the odds information K corresponding to the group number. tk For example, it can be calculated from (Equation 4) described later.

[0020] The differential support rate calculation unit 17 calculates the support rate S of each group number calculated by the support rate calculation unit 16. tk Based on this, the differential support rate ΔS for each group number (tk-t0) Ask for.

[0021] The display processing unit 18 displays the odds information K tk , support rate S tk , differential support rate ΔS (tk-t0) The information is retrieved from the storage unit 12 or the like, and processed in an appropriate form based on the information such as the type of display data and the time range desired to be displayed input by the user on the client terminal 50. The display processing unit 18 also generates image data to be displayed on the display unit 52 of the client terminal 50.

[0022] The output unit 14 transmits the data processed by the display processing unit 18 and the generated image data to the client terminal 50.

[0023] The storage unit 12 records data used in the information providing device 100. A database 21 is formed in the storage unit 12. The database 21 in this embodiment 1 is formed by a relational database, but any format, such as an object database, may be used as long as it is suitable for recording and rewriting large amounts of data. For example, the database 21 may store odds information K for each pair number that can be bet on in a predetermined race of a publicly managed game. tk , support rate S tk , differential support rate ΔS (tk-t0) , and time information tk are stored in association with each other.

For example, if the information providing device 100 is configured as a network computer system consisting of multiple server computers, each component may be distributed across multiple server computers. Furthermore, these server computers may be distributed across computer systems owned by multiple vendors or server administrators (e.g., computer systems owned or managed by other information providers, providers, hosting system providers, etc.). The server computers may be configured as a so-called cloud computer system. Furthermore, at least some of the components of the data processing unit 10, memory unit 12, input unit 13, output unit 14, timing unit 15, support rate calculation unit 16, differential support rate calculation unit 17, display processing unit 18, ranking display processing unit 19, and time progression display processing unit 20 may be provided in a client terminal 50 that constitutes the information provision system 1000, rather than in the information provision device 100.

[0025] Next, in the information providing system 1000 of the first embodiment, odds information K for displaying information on the client terminal 50 is tk The processing procedure will be explained below.

[0026] FIG. 2 shows odds information K for displaying information on the client terminal 50 in the information providing device 100 according to the first embodiment. tk 10 is a flowchart showing the processing procedure of

[0027] The information providing device 100 receives odds information K for a predetermined race held by a sponsor of a publicly managed race. tk The host system 1 acquires the odds information K tk The information providing device 100 is a server computer managed and operated by an information provider or organization that provides real-time data on races, including the 2016 Tokyo Olympics and Paralympics, and is equipped with a web server function and a database function for storing large amounts of data. The information providing device 100 receives user authentication from the upper system 1, for example, to request data, and obtains the data in response to the request using the receiving unit 11.

[0028] The information providing device 100 processes the acquired data. In the first embodiment, the data processing unit 10 processes the odds information K tk and time information tk are associated with each other (step S2), and are stored in the storage unit 12. tk The time information tk may be included in the data previously acquired by the receiver 11 from the host system 1. In this case, the odds information K tk and the time information tk may be stored as they are in the storage unit 12. If the data received by the receiving unit 11 does not include the time information tk, the time information tk output by the timing unit 15 may be stored as the odds information K tk The data is stored in the storage unit 12 in association with the above.

[0029] The information providing device 100 receives odds information K tk The index value of each group number is calculated based on the support rate S tk , differential support rate ΔS(tk-t0) etc., and odds information K tk The index value is obtained by processing the odds information K tk That very thing, approval rating S tk The ranking data for each group based on the differential support rate ΔS (tk-t0) The storage unit 12 may also include data on the ranking of each group number based on the time information tk, odds information K tk , support rate S tk A database 21 is constructed that associates the differential support rate ΔS (tk-t0) may be calculated each time a request from the client terminal 50 is received by the input unit 13, or may be calculated in advance and stored in the database 21 in association with the time information tk.

[0030] The information providing device 100 causes the index value processed by the data processing unit 10 to be displayed on the client terminal 50 (step S4). The display processing unit 18 processes the index value so as to display the data in a form according to the user request received by the input unit 13.

[0031] FIG. 3 is an example of a table that the information providing device 100 according to the first embodiment displays on the client terminal 50. This diagram shows the case of a horse race as an example, and the display content will be changed as appropriate for other publicly managed sports events. This diagram mainly displays basic information about the race, including the race name, race details, information about the participating horses, and odds information K. tk The M column is the horse number, which is the group number of the ticket in the case of a win bet. The K column is the odds information K tk The K1 column shows odds information for the win bet, and the K2 column shows odds information for the horse number consecutive bet. tk The K1 and K2 columns show other odds information K tk You can also display the odds information K tk Basically, the latest odds information tk However, odds information K tk You can also display the following.

[0032] In the embodiment, odds information K tk When the time information is displayed as t0, t1, t2, tk, the information providing device 100 displays the odds information K at each time. t0 , K. t1 , K. t2 ···K tk is obtained and stored.

[0033] 4A and 4B are examples of odds information for publicly managed races and index values ​​obtained by processing the odds information, which are processed by the information providing device 100 according to the first embodiment. tk This is an example of the odds information K that has been acquired and stored as the database 21. The information providing device 100 according to the first embodiment processes the acquired odds information K tk Based on this, the support rate S for each group number is as shown in Figure 4. tk , differential support rate ΔS (tk-t0) The information providing device 100 generates a database 21 that associates each piece of time information tk with the data. However, the database 21 generated by the information providing device 100 is not limited to the form shown in Fig. 4, and the way in which each piece of data is associated with the other pieces of time information tk can be changed as appropriate depending on the convenience of data processing.

[0034] Publicly managed sports events include horse racing, bicycle racing, auto racing, and boat racing, in which multiple horses or people compete in a race. Those who purchase betting tickets can receive a refund based on the results of the race. For example, in the case of Japan's national horse racing, the refund amount is set as follows: x=(W+D / P)×R (Formula 1) x: total refund amount W: Total face value of the pari-mutuel betting ticket for the winning horse D: Total face value of betting tickets for horses that have run in the race but are not the winning horse P: Number of winning horses R: Refund rate determined by the organizer for each voting method

[0035] In other words, for example, if the betting ticket type is a win bet, there will be one winning horse, and (Equation 1) will be as follows. x=(W+D)×R=X×R (Formula 2) X: All voting ticket denominations for that ticket type

[0036] If the odds for a certain group number are K, K can be calculated as follows: K={(W+D)×R} / W=(X×R) / W (Formula 3)

[0037] The above (Equation 3) can be transformed as follows: R / K=W / X=S... (Formula 4)

[0038] In Equation 4 above, W / X means (total face value of winning horse ticket) / (face value of all betting tickets of that ticket type), which corresponds to the winning horse's popularity rating S. Here, popularity rating S refers to the percentage of tickets purchased for that winning horse out of the total face value of all betting tickets of that ticket type. In publicly managed sports events, the payout rate R set by the organizer for each betting method (win bet, place bet, etc.) is fixed, so the popularity rating S of the winning horse can be calculated from the odds K for the winning horse's combination number. In JRA, the ticket types available for purchase as betting tickets include win, place, bracket bet, quinella, wide bet, exacta, trifecta, trifecta, and WIN5. Payout rates are set at 80.00% for win and place, 77.50% for bracket bet, quinella, wide bet, 75.00% for exacta and trifecta, and 72.50% for trifecta (as of May 2023). Note that the payout rate may vary depending on the sponsor and betting method of the publicly managed lottery, and therefore the information providing device 100 according to the first embodiment calculates the support rate S by changing the value to be substituted into the above formula (4) according to the payout rate R. The payout rate R is stored in the storage unit 12 of the information providing device 100, and is called up as appropriate and used to calculate each index value.

[0039] Referring to the race entry list shown in Figure 3, numerical values ​​are listed in the column for win odds K1. The numerical values ​​listed in the win odds K1 represent the expected multiple of the payout amount relative to the face value of the pari-mutuel betting ticket that will be obtained if each horse with the group numbers "1" to "8" wins. The win odds K1 are distributed from the host system 1, and are processed and displayed by the data processing unit 10.

[0040] While the example above was a win bet in JRA, in the case of a multiple bet such as WIN5, an amount "A / P" obtained by dividing the additional amount A by the number of winning horses P is added to the above (Equation 1). In this case, the support rate calculated above must be revised to take "A / P" into account. Furthermore, since the organizers of each publicly managed gaming event can set the payout rate R within a predetermined range, the payout rate R in the above (Equations 1) to (Equation 4) is adjusted appropriately depending on the type of betting ticket and the organizer's settings to calculate the support rate S.

[0041] In Figure 4, the odds information for the win type K tk 4(a) shows the process of the odds information K obtained by the information providing device 100 from the host system 1 shown in FIG. tk Figure 4(b) shows the odds information K tk Figure 4(c) shows the differential support rate ΔS, which is the change in the support rate S based on the time one hour before the voting deadline. (tk-t0) In Figure 4(c), the reference time t0 is 60 minutes before the voting deadline tf (11:15), and the support rate S tk and the support rate S at time t0 t0 4, the time is shown in 6-minute increments, but the increments can be changed as appropriate depending on how frequently the information providing device 100 acquires data from the higher-level system 1.

[0042] Odds Information K tkindicates the predicted value of how many times the payout will be received for the amount of the betting ticket purchased. In other words, the predicted odds for the final deadline for the betting ticket "1" in Figure 4 are shown as "4.7", and in this case, if you purchase a betting ticket for 100 yen, you will receive a payout of 470 yen. However, the odds shown in Figure 4(a) are the predicted odds at a certain time tk announced by the organizer, and do not necessarily match the payout rate that will be received after the race result is determined. Odds information K tk The number of bets will fluctuate depending on factors such as ticket sales and horses withdrawing from the race before the race.

[0043] Figure 4(a) shows the fluctuations in win odds for horses with group numbers "1" to "8" in Figure 2. In horse racing, the number assigned to each horse is sometimes called a horse number, and for win and place betting tickets, these horse numbers become the group number on the betting ticket. For consecutive betting tickets, the combination of horse numbers becomes the group number. In the race list shown in Figure 2, the horse numbers and gate numbers match, but if there are nine or more horses entered, multiple horses will be placed in one gate. The combination of gate numbers becomes the group number, and it is also possible to purchase a betting ticket (gate number consecutive betting).

[0044] FIG. 4(a) shows the odds for the win bet as described above. The horizontal rows at the top of the table show the times up until the voting deadline, and the columns below show the odds for each pair number at that time. The odds for each pair number fluctuate, and the information providing device 100 receives odds information K from the host system 1 at the receiving unit 11. tk The data processing unit 10 associates the time information tk with the odds of each combination number and stores them in the storage unit 12. The time information tk may be generated by the clock unit 15, or the receiving unit 11 may receive the odds information K tk In FIG. 4, the 60 minutes before the voting deadline is set as time t0, and the times t1, t2, ... are indicated by symbols toward the deadline tf. Therefore, the odds data for the pair numbers "1" to "8" 60 minutes before shown in FIG. 4(a) is used as odds information K t0 After that, the odds information for each time is called K t1 , K. t2 ,···,Ktf It is called.

[0045] FIG. 4(b) shows odds information K tk Support rate S tk The data is converted into the following, and the support rate S t0 , S t1 , S t2 ,···,S tf These support rates are the support rates S calculated using the above formula (4).

[0046] Figure 4(c) shows how the support rate fluctuates at each time, with the support rate S0 60 minutes before the deadline as the base. tk Support rate S 60 minutes before t0 In each column of Figure 4(c), if a negative value is shown, it means that the support rate S has decreased since 60 minutes ago. tk A positive value indicates that the support rate S has decreased compared to 60 minutes ago. tk means that has risen.

[0047] 4 shows an example of data processed by the data processing unit 10 of the information providing device 100, and these data are stored in the storage unit 12 and can be called up as needed. Also, although a win bet is shown as an example, the information providing device 100 can also calculate the support rate S of each pair of numbers from the odds for consecutive win bets and place bets. tk can be calculated, stored and displayed.

[0048] FIG. 5 shows the information providing device 100 according to the first embodiment providing odds information K tk 5 is a diagram illustrating the flow of data for processing the odds information K shown in FIG. tk The receiving unit 11 receives the odds information K from the host system 1. tk is sent to the data processing unit 10, and the time information tk or odds information K tk The time information tk and the odds information K tk Both are stored in the memory unit 12. In addition, the odds information Ktk is calculated as the support rate S tk This support rate S tk The odds information K tk , time tk, support rate S tk are stored in the storage unit 12 and can be called up as needed.

[0049] The data processing unit 10 also calculates the support rate S tk Based on the differential support rate ΔS (tk-t0) Calculate the differential support rate ΔS (tk-t0) is the support rate S at a certain first time t0 and the support rate S at any second time tk The difference between the two is the difference between the differential support rate ΔS (tk-t0) are also stored in the storage unit 12. The first time that serves as a reference for comparison may be referred to as a reference time, and the second time that is the comparison target may be referred to as a comparison time.

[0050] The odds information K for each group number obtained by the data processing unit 10 tk , support rate S tk , differential support rate ΔS (tk-t0) is processed by the display processing unit 18. For example, based on information P input by the user at the client terminal 50, the display processing unit 18 processes odds information K stored in the storage unit 12. tk , support rate S tk , differential support rate ΔS (tk-t0) The display processing unit 18 processes the data and sends it to the output unit 14.

[0051] In addition, the ranking display processing unit 19 displays the odds information K tk , support rate S tk , differential support rate ΔS (tk-t0) The ranking display processing unit 19 compares each group number with the odds information K tk , support rate S tk , or differential support rate ΔS (tk-t0) Rearrange each group number according to the order of the above.

[0052] 6 shows an example of information displayed on the client terminal 50 in the information providing system 1000 according to the first embodiment. (tk-t0) is calculated for each group number, and the differential support rate ΔS (tk-t0) The ranking display processing unit 19 calculates the differential support rate ΔS of each group number at an arbitrary time. (tk-t0) Compare the difference in support rate ΔS (tk-t0) The group numbers can be rearranged in order from 1st to the lowest according to the value of . Note that what is displayed on the display unit 52 of the client terminal 50 may be at least a part of the ranking of the group numbers.

[0053] Figure 6 shows the differential support rate ΔS for each group at the time of voting closing. (tk-t0) This is an example of a table that arranges information in the order of the group numbers based on the odds. In the table shown in Figure 6, the left side shows the change in odds at the closing time, based on 60 minutes before the voting deadline, and the right side shows the change in support rate. In this table, the increase or decrease in support rate in a certain race, that is, the difference in support rate ΔS (tk-t0) The group numbers are arranged from top to bottom in descending order of odds. tk , support rate S tk The change in is also shown.

[0054] In the table of Figure 6, the reference time t0 is set to 60 minutes before the voting deadline, and the time tk to be compared is displayed as the voting deadline tf. The difference in support rate ΔS immediately after the voting deadline is (tk-t0) Based on the ranking and odds information for each group number K tk , support rate S tk However, the reference time t0 and the time tk to be compared can be set freely. For example, the user sets the time t0 and the time tk by operating the operation unit 51 of the client terminal 50, and the information providing device 100 receives the information as information P. Based on the information P, the display processing unit 18 calls up information from the storage unit 12 as appropriate, processes the information as necessary, and sends it to the output unit 14. The output unit 14 sends the processed information as output Q to the client terminal 50.

[0055] The information displayed on the display unit 52 of the client terminal 50 can be changed as needed. For example, the odds information K tk , support rate S tk , and differential support rate ΔS (tk-t0) Some of the numerical values ​​may not be displayed. In addition, the order of the group numbers does not have to be rearranged and displayed, but the order may be expressed by numbers or by color-coding the columns. For example, each column of the table displayed on the display unit 52 may be (tk-t0) The display may be such that it is easy to visually classify, for example, blue for positive values ​​(when approval rating is increasing), green for 0 (or close to 0), and red for negative values ​​(when approval rating is decreasing).

[0056] 7 is an example of information displayed on the client terminal 50 in the information providing system 1000 according to the first embodiment. (tk-t0) 7 is a graph showing the transition of the differential support rate ΔS (tk-t0) The odds information K tk Or approval rating S tk The graph format is not limited to a line graph, and other formats may be used.

[0057] (Operation of the First Embodiment) Usually, in publicly managed games, users can only obtain odds information K expressed as a payout ratio from the organizer. tk When a user wants to purchase a betting ticket, the latest odds information K available at that time tk is used. tk However, the odds information K tkThe odds only show the payout ratio relative to the purchase price of the betting ticket, so when comparing multiple betting numbers, it is difficult to instantly determine how popular a betting number is and how much of a difference in popularity there is just by looking at the odds numbers.

[0058] Also, if a certain set number is popular, even if a large number of tickets are purchased for that set number, the fluctuation in the odds is small. Therefore, even if a certain set number is actually popular and a large number of tickets are purchased at a certain point in time, it is difficult to grasp the fluctuation just by looking at the odds, especially for set numbers that are already popular.

[0059] In the information providing system 1000 according to the first embodiment, odds information K tk Support rate S tk This allows users to understand the overall voting situation in more detail and use this information to make decisions about purchasing voting tickets.

[0060] Furthermore, in the information providing system 1000 according to the first embodiment, a first time and a second time are selected, and the change in the support rate between the first time and the second time (the difference support rate ΔS (tk-t0) ) can be displayed on the display unit 52 of the client terminal 50, and the differential support rates ΔS (tk-t0) This allows users to understand the voting situation in more detail for a certain period. tk Since the information is limited to one decimal place, the desired support rate S tk The accuracy of the odds information is limited, and the calculation results may have errors. However, in order for users to use the odds information as a basis for deciding whether to purchase a betting ticket, tk It is sufficiently usable compared to the case of only.

[0061] Generally, when buying a ticket for a publicly managed race, the basis for deciding whether to buy a ticket is the race results of the horses and runners participating. Information about the horses and runners participating in the race is diverse, and can be found in newspapers, on television, or on the Internet. People who buy tickets decide which bets to buy while looking at this information, but for example, in horse racing, as the race deadline approaches, such as when the horses make their rounds in the paddock or when they enter the main racecourse, information is provided that tells them the condition of the participating horses that day, so some people may check this information before buying a ticket. Therefore, for example, in horse racing, the support rate S after events such as the end of paddock and entry into the main racecourse is tk It can be said that the change in the differential support rate ΔS represents the evaluation of the horses participating in the event. According to the information provision system 1000 of the first embodiment, the user can specify the first time and the second time, and the differential support rate ΔS for that period can be calculated. (tk-t0) can be displayed on the client terminal 50. For example, the differential support rate ΔS can be displayed by specifying a time including the time when the paddock tour is being performed. (tk-t0) By displaying this, you can understand the overall status of ticket purchases at that time.

[0062] As described above, according to the information providing system 1000 of embodiment 1, the user can specify any time and get a more detailed understanding of the popularity rate and changes in the popularity rate of each group number that is the target for betting on a betting ticket, and use this information as information for purchasing a betting ticket.

[0063] Embodiment 2 The information providing system 1000 according to the second embodiment provides odds information K tk In addition to the vote count information V tk The second embodiment mainly describes the modified parts of the first embodiment.

[0064] FIG. 8 shows odds information K for displaying information on the client terminal 50 in the information providing device 100 according to the second embodiment. tk and vote count information V tk10 is a flowchart showing a processing procedure of the information providing device 100 according to the second embodiment. tk Not only the number of votes but also the number of votes tk (Step S1), and associate the time information tk with them (Step S2). tk and vote count information V tk are stored in the storage unit 12 and organized into a database.

[0065] The information providing device 100 receives odds information K tk The index value of each group number is calculated based on the support rate S tk , differential support rate ΔS (tk-t0) etc., and odds information K tk In addition to the vote count information V tk In the second embodiment, the index value is processed by a predetermined method using odds information K tk and approval rating S tk The individual votes for each group calculated from v tk , Odds Information K tk , support rate S tk and the number of individual votes v tk The differential support rate ΔS calculated from (tk-t0) It may also include the following.

[0066] The information providing device 100 causes the index value processed by the data processing unit 10 to be displayed on the client terminal 50 (step S4). The display processing unit 18 processes the index value so as to display the data in a form according to the user request received by the input unit 13.

[0067] FIG. 9 shows the information providing device 100 according to the second embodiment providing odds information K tk and vote count information V tk 9 is a diagram illustrating the flow of data for processing the odds information K from the upper system 1. FIG. 10 is an example of an index value processed by the information providing device 100 according to the second embodiment. As shown in FIG. 9, the information providing device 100 receives the odds information K from the upper system 1. tk and vote count information V tk The data processing unit 10 receives the odds information K tk From approval rating Stk This support rate S tk is shown in Figure 10(a).

[0068] The information providing device 100 generates the vote count information V as shown in FIG. tk Also obtained is the number of votes V tk is the total number of votes for a certain ticket type that can be purchased as a betting ticket. For example, in the case of a race such as the one shown in Figure 3, it represents the total number of votes for win betting tickets at a certain time tk, and the total number of betting tickets for each of the combination numbers "1" to "8" is displayed in each column of Figure 10(b).

[0069] The data processing unit 10 calculates the support rate S tk and the vote count information V shown in Fig. 10(b) tk Multiplying by and, the individual vote count v for each group at time tk tk The individual vote count calculation unit 24 calculates the individual vote count v tk are shown in each column of Figure 10(c). For example, by multiplying "20.5%" in the 10:15 column of the group number "1" shown in Figure 10(a) by "122563" in the 10:15 column of the number of votes shown in Figure 10(b), the number of individual votes "25141" in the 10:15 column of the group number "1" in Figure 10(c) is obtained. The number of individual votes at each time for other group numbers can be calculated in the same way. The number of individual votes for each group number v tk is stored in the storage unit 12. At this time, the individual vote count v tk is associated with time information tk.

[0070] The data processing unit 10 calculates the number of individual votes v tk Based on the difference in votes, Δv (tk2-tk1) The differential vote number calculation unit 25 calculates the differential vote number Δv (tk2-tk1) is the number of votes v for a certain group at the second time tk2. tk2 and the number of votes at the first time tk1, v tk1This can be calculated from the difference between the number of votes cast for a group number from the specified first time tk1 to the second time tk2. The first time tk1 is a time before the second time tk2, and the first time tk1 and the second time tk2 can be selected freely. Specifically, the difference in the number of votes cast from 10:15 to 10:21 can be calculated by subtracting the number of votes cast at 10:15 (25141) from the number of votes cast at 10:21 (29886) for group number "1" shown in Figure 10(c).

[0071] The data processing unit 10 also calculates the number of votes information V tk Based on the difference in total votes, ΔV (tk2-tk1) This is the vote count information V at the second time tk2 shown in FIG. 10(b). tk2 and the vote count information V at the first time tk1 tk1 Specifically, by subtracting the number of votes at 10:15 (122563) from the number of votes at 10:21 (145698) in Figure 10(b), the total difference in the number of votes from 10:15 to 10:21 can be calculated. This gives the total number of votes cast for a certain bill type from the specified first time to the specified second time.

[0072] The data processing unit 10 calculates the difference vote number Δv (tk2-tk1) and the total number of differential votes ΔV (tk2-tk1) Based on the period support rate δS (tk2-tk1) 10(d) shows the period support rate ΔS of each group number in each period from time t0 to t1, t1 to t2, t2 to t3, . . . , t9 to t10. (t1-t0) , δS (t2-t1) , , δS (t10-t9) The period support rate δS shown here is (tk2-tk1) is calculated using the following formula: δS (tk2-tk1) =(v tk2 -v tk1 ) / (V tk2 -V tk1 )...(Formula 5) Here, the first time tk1 and the second time tk2 can be freely selected.tk2 -v tk1 ) is the differential vote count Δv (tk2-tk1) and (V tk2 -V tk1 ) is the difference in the total number of votes ΔV (tk2-tk1) is.

[0073] FIG. 10(d) shows the period support rate ΔS for each of the times t0 to t1, t1 to t2, t2 to t3, . . . , t9 to t10, using the above (Equation 5). (tk2-tk1) Specifically, the popularity rate of each group number in each period is calculated in 6-minute increments. In the information providing system 1000, the time increment can be changed as appropriate depending on the frequency at which the information providing device 100 acquires data from the upper system 1.

[0074] FIG. 11 shows the period support rate δS of each group number in FIG. 10(d). (tk2-tk1) The graph shows the trend of the period support rate δS (tk2-tk1) Since ΔS is a support rate limited to a certain specified period, if there are a large number of votes for a certain group number during a certain specified period, the value may become large. In Fig. 10 and Fig. 11, the support rate for each period is calculated in 6-minute increments, but in reality, the information provision system 1000 calculates the support rate ΔS for a period from an arbitrary first time to an arbitrary second time specified by the user. (tk2-tk1) can be freely displayed on the display unit 52 of the client terminal 50.

[0075] Furthermore, the information providing system 1000 calculates the period support rate ΔS (tk2-tk1) The order of each group number based on this can be displayed on the display unit 52 of the client terminal 50.

This allows users to perform various analyses, such as understanding the voting behavior of people who watched an event such as the racer's entry into the main racecourse.

[0077] (Variation) 12 is a modified example of the information providing system 1000 according to the first and second embodiments. The information providing system 1000 uses a differential support rate ΔS (tk-t0) and period support rate δS (tk2-tk1) The information providing device 100 may be provided with a betting target determination unit 30 that not only provides the above information but also calculates the ranking of each group number using these numerical values ​​and presents betting targets when the user purchases a betting ticket. The betting target determination unit 30 displays one or more top betting targets based on the ranking of each group number on the client terminal 50, based on instructions from the user input to the input unit 13. Alternatively, if the client terminal 50 is equipped with a betting ticket purchase function, the betting target determination unit 30 may be configured to send the betting targets output by the betting target determination unit 30 directly to the betting ticket purchase function, allowing automatic or semi-automatic purchase of betting tickets. When the betting target determination unit 30 determines betting targets, the user sets in advance the type of betting ticket, the purchase amount, how many betting tickets to purchase according to which index value ranking, etc. Furthermore, the user may input the period support rate δS (tk2-tk1) It is also possible to set a threshold value for the betting price, and set it to pick up and present the combination numbers that exceed this threshold. By providing such a betting recommendation determination unit 30, the information provision system 1000 can quickly determine the differential support rate ΔS even just before the voting deadline. (tk-t0) and period support rate δS (tk2-tk1) Since it is possible to determine the bets using index values ​​other than the payout rate, such as the above, it is possible to prevent missing opportunities to purchase betting tickets.
