An impression of heel can be given, and thus the anxiety generated when the advertising subject uses a service provider for a different industry for the first time can be reduced.

  Furthermore, according to the information introduction device of claim 3 of the present invention, since the correlation rule is established when the certainty factor and the support degree are equal to or greater than the predetermined value, the condition for establishing the correlation rule can be clarified, and thus An advertising target person can be easily specified based on the correlation rule from among a plurality of settlers.

  Furthermore, according to the information introduction apparatus of claim 4 of the present invention, the use of the service provider of the different industry based on the advertisement information for the advertising target who is estimated to be highly likely to use the service provider of the different industry. Thus, it is possible to propose an information introduction device that can easily acquire new customers.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  In FIG. 1, reference numeral 1 denotes an information introduction system, which includes an information introduction server 3 installed by a card issuer 2, and a plurality of store terminal devices 4a, 4b and 4c installed at each store contracted with the card issuer 2. It is composed of

  Here, the card issuer 2 registers personal information such as its own name and address, age, gender, account number of the financial institution, and e-mail address of the client terminal 6 owned by the user in the information introduction server 3. As a result, the credit card 7 on which an IC (Integrated Circuit) chip is mounted is issued to the user.

  Each user (hereinafter referred to as a card user) 5 to whom the credit card 7 has been issued can make a settlement using the credit card 7 when receiving service from various service providers. In the case of this embodiment, as the service provider, for example, the airliner A1, the accommodation company B1, and the rental car company C1 will be described below. However, the present invention is not limited to this and is not limited to this. Various other service providers may be applied.

  For example, when the card user 5 as a settlement person purchases a ticket from the airliner A1, the credit card 7 is loaded into the store terminal device 4a. As a result, the store terminal device 4a is connected online to the information introduction server 3 via the network 8, and is entered by the card user 5 himself / herself with payment history data including the name of the air carrier A1, the number of tickets, ticket price, payment date and time, etc. The obtained password data is transmitted to the information introduction server 3.

  The information introduction server 3 executes authentication processing of personal information based on the personal identification number data. When the identity of the five card users is confirmed, the information introduction server 3 transmits settlement permission data to the store terminal device 4a. As a result, the store terminal device 4a can execute a payment process based on the payment permission data.

  Thus, each card user 5 purchases a ticket from the airliner A1 without paying the airliner A1 directly by making a payment to the airliner A1 by the card issuer 2 and making a payment to the airliner A1. be able to. Incidentally, the information introduction server 3 can execute a billing process for deducting a settlement fee from an account of a financial institution with which the card user 5 has contracted, for example, once a month based on the settlement history data. Yes.

  In addition to this configuration, the information introduction server 3 manages a plurality of card users 5 whose addresses, ages, and genders are matched as a group based on the personal information of each card user 5, Understand the tendency of each airliner A1, lodging agent B1 and rental car agent C1 (hereinafter collectively referred to simply as service agents) for each group, and based on the obtained trends The federated advertisement information (described later) that prompts each identified card user 5 to use a new service provider can be distributed via the network 8.

  Incidentally, in the above-described embodiment, the case where the federated advertisement information is distributed to the client terminal 6 via the network 8 has been described. However, the present invention is not limited to this, and the federated advertisement information is printed on a paper medium. Then, it may be mailed to the card user 5.

  In practice, as shown in FIG. 2, the information introduction server 3 includes a control unit 10 having a microcomputer configuration including a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like (not shown). A credit settlement processing unit 11, a history information database 12 as a management means, a correlation rule generation unit 13, a correlation rule database 14, a federated advertisement information generation unit 15, a company introduction information database 16, a network interface 17, Are connected to each other via a bus 18.

  The control unit 10 can centrally control various functions in the information introduction server 3 by loading various programs such as a basic program stored in advance in the ROM and an information introduction processing program into the RAM and starting up the program. Data communication is performed via the network interface 17 between the store terminal devices 4a, 4b and 4c, the client terminal 6 owned by each card user 5 and the information processing device (not shown) owned by the financial institution. Has been made to get.

  The company introduction information database 16 includes industry information representing the industry of the service provider using the information introduction system 1, introduction text introducing each service content of the service provider, image images of the service provider, and the like. Is stored.

  On the other hand, personal information of each card user 5 is stored in the history information database 12 in advance, and payment history data received from the store terminal devices 4a, 4b and 4c via the network interface 17 is stored for each personal information. It can be stored in association with each other.

  The control unit 10 uses the personal information stored in the history information database 12 and the personal identification number data and the payment history data received via the network interface 17, by the credit payment processing unit 11, by the store terminal device 4a, A general settlement process can be executed between 4b and 4c, and an accounting process can be executed with an information processing apparatus (not shown) owned by the financial institution.

  In addition to this configuration, the control unit 10 creates a management table T1 having a format as shown in FIG. 3, for example, based on the personal information and settlement history data of each card user 5, and stores it in the correlation rule database 14.

  In the case of this embodiment, the management table T1 includes the “region” column D1 indicating the address of the card user 5, the “age” column D2 indicating the age group of the card user 5, and the gender of the card user 5. A plurality of card users 5 having a “sex” field D3 to be shown and a “card user name” field D4 for identifying the card user 5 and having the same address, age group and gender of the card user 5 Can be managed together as a group.

  For example, if each of the card users 5 of “A”, “B” and “A” is a male in his 20s who has an address in Tokyo, as shown in FIG. 3, these “A”, “B” and “A” Can be managed together as one group G1 in the management table T1.

  In addition, in this management table T1, women in their 20s who have addresses in Tokyo are group G2, men in their 30s who are in Tokyo are group G3, and women in their 30s who are in Tokyo are group G4. Users 5 can be managed together. Although not shown in FIG. 3, a plurality of card users 5 having the same age group and gender can be managed together in each region such as Saitama Prefecture and Chiba Prefecture.

  In addition to this, the management table T1 includes an “industry” column D5 indicating the service provider that each card user 5 has settled with the credit card 7, and is classified according to the type of industry. It is possible to manage which service provider is used in the industry.

  That is, when receiving the payment history data via the network interface 17, the control unit 10 recognizes what type of business the service provider of the payment history data is based on the industry information stored in the company introduction information database 16. Then, the service provider name is recorded in the “business type” column D5 of the corresponding “card user name” column D4 in the management table T1.

  In the case of FIG. 3, for example, an “industry” column D5 includes an “airline agent” column D5a, an “accommodation agent” column D5b, a “rental car dealer” D5c column, and the like. For example, when each of the card users 5 of “A” and “B” stays at the accommodation company B1 using the airliner A1, rents a car at the rental car company C1, and makes a settlement with the credit card 7, Based on the payment history data received from the store terminal devices 4a, 4b, and 4c, “A1” is displayed in the “Airliner” column D5a of “Exhibitor A” and “O” in the “Card user name” column D4 in the management table T1. “B1” is associated with the “accommodation agent” column D5b, and “C1” is associated with the “car rental agent” column D5c.

  Further, for example, when “丙” as the card user 5 stays at the lodging agent B1 using the airliner A1, but does not rent a car, it is based on the settlement history data received from the store terminal devices 4a and 4b. In the management table T1, “A1” is associated with the “air carrier” field D5c of “丙” in the “card user name” field D4, and “B1” is associated with the “accommodation agent” field D5b. The In FIG. 3, “-” described in the “rental car dealer” column D5c of “丙” in the “card user name” column D4 indicates that no payment has been made.

  Similarly, when a woman in her 20s who has an address in Tokyo, for example, stays at a lodging company B1 using an airliner A2, rents a car at a rental car company C2, and completes a settlement with a credit card 7, the network Based on the settlement history data received via the interface 17, “A2” is associated with the “air carrier” column D5a for the corresponding “card user name” column D4 in the group G2 column of the management table T1, and “ “B1” is associated with the “accommodation agent” column D5b, and “C2” is associated with the “car rental agent” column D5c (FIG. 3).

  In this way, every time the control unit 10 receives payment history data from each of the store terminal devices 4a, 4b and 4c, the “card user name” of the corresponding group G1, G2, G3,... In the management table T1. The column D4 is specified, and the service provider name included in the settlement history data is recorded in the corresponding category of the “business type” column D5.

  And the correlation rule production | generation part 13 uses the management table T1 memorize | stored in the correlation rule database 14, and shows the tendency of what service provider is used for each group G1, G2, G3, ... It is grasped for each business type, and based on the obtained tendency, it is determined whether a correlation rule between different business types can be established for each group G1, G2, G3,. Here, the correlation rule is a rule that the card user 5 who uses a certain service provider has a high probability of using another service provider (different industry service provider) having a different industry relationship with this card user. is there.

  In the case of this embodiment, the correlation rule generation unit 13 uses, as the correlation rule, a processing method that evaluates a rule based on, for example, confidence and support, and each group G1, G2, G3,. The certainty factor and the support factor are calculated every time, and it is determined that the correlation rule can be established when the certainty factor and the support factor are equal to or greater than a predetermined value.

  The certainty factor here indicates the probability that a conclusion will occur with respect to the precondition. For example, when the premise is that “a certain service provider is used”, this precondition is satisfied. Predetermined card user 5 shows the rate at which the conclusion that “it is also used by other service providers that have a different business relationship with this” is generated, and the higher the number, the more the association between the preconditions of the association rule and the conclusion It means to be strong.

  On the other hand, the support level indicates the probability that both the precondition and the conclusion are generated in all data of each group G1, G2, G3,..., And each group G1, G2, G3 in the management table T1. ... Shows the ratio of the occurrence of the combination. If this numerical value is extremely low, it means that the association rule is difficult to be established in each group G1, G2, G3,.

  Incidentally, as shown in FIG. 3, for example, in group G1, it is assumed that both airliner A1 and hotel carrier B1 that has a different industry relationship with airliner A1 are used, and this precondition is satisfied. When each card user 5 assumes that the association rule indicating the estimation result (conclusion) that the car rental company C1 having a different industry relationship with the card user 5 is used with a high probability is established, the certainty level and the support level are as follows. It is calculated as follows.

  The certainty factor is that in Group G1, the number of card users who have a payment history for all three companies, airliner A1, lodging agent B1 and rental car company C1, and that there is a payment history for two companies, airliner A1 and accommodation carrier B1. It can be calculated by dividing by the number of card users that satisfy the condition. At this time, the degree of support is divided by the number of card users belonging to the group G1 in the group G1 and the number of card users who have a settlement history for all three companies of the airliner A1, the accommodation company B1 and the rental car company C1 Can be calculated.

  The correlation rule generation unit 13 as the generation unit and the identification unit calculates the certainty factor and the support factor as described above, and when the certainty factor and the support factor are equal to or greater than a predetermined value set in advance, between these different industries. Although it is determined that the correlation rule is established and the group G1 that generated the correlation rule satisfies the precondition that the airliner A1 and the accommodation company B1 are used, the car rental company C1 is still used. A plurality of card users 5 (hereinafter referred to as advertisement target persons) can be specified.

  When the association rule is established by the above-described determination, the federated advertisement information generation unit 15 serving as the advertisement generation unit obtains the company introduction information of the airliner A1 and the accommodation company B1 based on the preconditions of the association rule. , And the company introduction information of the rental car dealer C1 is read out from the company introduction information database 16 on the basis of the estimation result to generate federated advertisement information.

  The control unit 10 can distribute the associated advertisement information only to the client terminal 6 owned by each advertisement target person specified by the association rule via the network interface 17 serving as a distribution unit.

  Thus, when each client terminal 6 receives the federated advertisement information as the advertisement information, as shown in FIG. 4, the company introduction area 31 of the airliner A1, the company introduction area 32 of the accommodation company B1, and the car rental company C1. The company introduction area 33 and the guidance statement that profit return processing is performed for the advertising target person when the payment by the credit card 7 is made to all the airliner A1, the accommodation agent B1, and the rental car agent C1. The associated advertisement screen 35 including the guidance sentence area 34 is displayed on the display unit.

  Thus, the information introduction server 3 displays the federated advertisement screen 35 on the client terminal 6 of each advertisement target person who has a high possibility of using the car rental company C1 as a service provider of a different industry. The company introduction information of the airliner A1, the accommodation company B1 and the rental car company C1 is presented at the same time, and not only the airliner A1 and the accommodation company B1 but also each advertisement target person now It is intended to encourage the use of a rental car dealer C1 who has never used it.

  Incidentally, in the case of this embodiment, the information introduction server 3 manages the points given in accordance with the payment of the credit card 7 in the history information database 12 for each card user 5. Then, the information introduction server 3 confirms by the payment history data that each advertising target person has made a payment with the credit card 7 in all of the airliner A1, the accommodation company B1 and the rental car company C1 included in the federated advertisement information. Profit return processing is executed to increase the number of points given by the payment by the credit card 7 more than usual. Incidentally, the information introduction server 3 executes, for example, a discount process for discounting the price, a delivery arrangement process for giving novelties, etc. according to the accumulated number of points.

  In the case of this embodiment, the information introduction server 3 provides the airliner A1, the accommodation company B1 and the car rental company C1 who distributed the company introduction information to the respective advertisement target persons by the federated advertisement information for the points given by the profit return process. A point burden request can be transmitted to each information processing device (not shown) owned by the airliner A1, the accommodation agent B1, and the rental car agent C1.

  At this time, for example, the information introduction server 3 has more points than the other airliner A1 and accommodation agent B1 for the rental car dealer C1 who has been able to present his company introduction information to a new advertising target person who has no usage history. The burden on the number of points of the airliner A1 and the accommodation company B1 can be reduced.

  As a result, although the airliner A1 and the accommodation company B1 are required to bear the number of points, the burden of the number of points is reduced, and the company introduction information can be presented to a plurality of advertising targets. Encourage target users to use the company.

  Next, the information introduction processing procedure described above will be briefly described using a flowchart. As shown in FIG. 5, the control unit 10 starts the information introduction processing procedure RT1 from step SP1 and determines whether payment history data has been received from the store terminal devices 4a, 4b and 4c.

  If a negative result is obtained in step SP1, this means that the settlement history data is not transmitted from the store terminal device 4a, 4b or 4c to the information introduction server 3, that is, each card user 5 uses the credit card 7. This means that no payment is made with the service provider, and at this time, the control unit 10 waits for payment history data from the store terminal devices 4a, 4b and 4c.

  On the other hand, if a positive result is obtained in step SP1, this means that the payment history data has been received from the store terminal device 4a, 4b or 4c via the network interface 17, that is, any of the card users 5 This shows that payment was made with a service provider using the credit card 7, and at this time the control unit 10 proceeds to the next step SP2.

  In step SP2, the control unit 10 executes an association rule generation process using the settlement history data for each group G1, G2, G3,..., And proceeds to the next step SP3.

  In step SP3, the control unit 10 determines whether or not the correlation rule is established based on whether or not the certainty factor and the support factor calculated by the correlation rule generation process are equal to or greater than a predetermined value set in advance. Here, if a negative result is obtained, this means that the certainty factor and the support factor are less than the predetermined value, that is, the correlation rule is not established, and at this time, the control unit 10 again performs the step. Returning to SP1, the above-described processing is repeated.

  On the other hand, if a positive result is obtained in step SP3, this indicates that the certainty factor and the support factor are equal to or greater than the predetermined value, that is, the correlation rule is established. At this time, the control unit 10 The next step SP4 is entered.

  In step SP4, the control unit 10 executes the combined advertisement information generation process, so that the company introduction information of the airliner A1 and the accommodation company B1 based on the preconditions of the association rule and the company of the car rental company C1 based on the estimation result. The introduction information is read from the company introduction information database 16, and the combined advertisement information to which the company introduction information and the guidance text are attached is generated, and the process proceeds to the next step SP5.

  In step SP5, the control unit 10 distributes the fed advertisement information to the client terminal 6 owned by each advertisement target person who has estimated that the car rental company C1 will be used based on the association rule, and proceeds to the next step SP6 to move to the above-described step SP6. The process ends.

  In the above configuration, the information introduction server 3 simply receives the payment history data, and the correlation rule generation unit 13 determines whether or not a correlation rule is established between different industries for each group G1, G2, G3,. As a result of the determination, for each group G1, G2, G3,..., A group of a plurality of card users 5 having the same address, age group, and gender, what card user 5 is currently different from what Accurate association rules that indicate which service providers tend to use between industries can always be generated.

  In the information introduction server 3, for example, in the group G1, it is assumed that the airliner A1 and the accommodation company B1 are used, and each card user 5 that satisfies the preconditions tends to use the car rental company C1. If the correlation rule showing the presumed result is established, each advertisement that has the settlement history of the credit card 7 for the airliner A1 and the accommodation company B1 and satisfies the preconditions, but has not yet used the car rental company C1. The target person is identified from within the group G1 based on the association rule.

  The information introduction server 3 reads out the company introduction information of the car rental company C1 from the company introduction information database 16 based on the estimation result of the correlation rule, generates federated advertisement information with the company introduction information of the car rental company C1 attached, By distributing the federated advertisement information to the client terminal 6 owned by the advertising target person, the rental car company C1 is only given to each advertising target person who is most likely to use the rental car company C1 in the group G1. The company introduction information can be presented efficiently.

  At this time, the information introduction server 3 also presents the company introduction information of the airliner A1 and the accommodation company B1 that each advertisement target person has used in the past by the federated advertisement information. About the rental car dealer C1 that each advertisement target has not used in the past, it can give an impression that it may have some relationship with the air carrier A1 and the accommodation contractor B1 that have been used in the past. It is possible to reduce the anxiety that occurs when each advertisement target person uses the rental car dealer C1 for the first time.

  Further, the information introduction server 3 makes a new payment with the credit card 7 to the airliner A1 and the accommodation agent B1, and uses the credit card 7 for all three companies of the airliner A1, the accommodation agent B1 and the car rental agent C1. By executing profit return processing for increasing the number of points for each advertisement target person who made a settlement, not only the rental car company C1 but also the use of the airliner A1 and the accommodation company B1 The target person can be urged.

  Further, in the case of this embodiment, the information introduction server 3 makes it possible to clarify the conditions for establishing the correlation rule by establishing the correlation rule when the certainty factor and the support level are equal to or greater than the predetermined value. A predetermined advertising target person can be easily specified from among the card users 5 based on the correlation rule.

  According to the above configuration, the possibility of using the rental car dealer C1 is high based on the correlation rules established for each group G1, G2, G3,... Based on the payment history data of a plurality of card users 5. By characterizing each estimated advertisement target and generating the associated advertisement information including the company introduction information of the rental car dealer C1, the associated advertisement information is presented to each advertisement target person to rent a car. The information introduction server 3 that can prompt the use of the trader C1 and can easily acquire a new customer can be proposed.

  The present invention is not limited to this embodiment, and various modifications can be made within the scope of the present invention. For example, a debit card may be used instead of the credit card 7, or the client terminal 6 A mobile phone with an electronic money processing function in which the credit card 7 and the credit card 7 are integrated may be applied, or simple advertisement information other than the federated advertisement information may be generated and presented.

  Furthermore, in the above-described embodiment, a case has been described in which card users whose regions, age groups, and genders are managed as a group are collectively managed as a group. However, the present invention is not limited to this. , Manage multiple card users that match any one of region, age group and gender as a group, or match multiple other genres such as occupation, school, hometown, etc. You may make it manage a card user collectively as one group.

  Furthermore, in the above-described embodiment, as a condition for establishing the association rule, the case where the association rule is established when the certainty factor and the support degree are equal to or greater than a predetermined value has been described, but the present invention is not limited thereto. The settlement history data of a plurality of target card users 5 in the group and the other plurality of card users 5 are compared, and the settlement history data is similar to that of the plurality of target card users 5. Search for a plurality of card users 5 and correlate service providers to which the target card user 5 has not yet received service out of the service providers that have received the services. A rule estimation result may be used, or various other correlation rules may be applied.
