  FIG. 1 is a conceptual diagram of an information system 1 in the present embodiment. The information system 1 includes a server device 11, one or more terminal devices 12, and an approval server 13. The server device 11 is a device that selects product information and performs automatic purchase processing. The terminal device 12 is a terminal of a user who purchases a product. Furthermore, the approval server 13 is a server that performs an approval process. The product is a purchase target, and includes not only a tangible product but also a so-called intangible service.

  FIG. 2 is a block diagram of the information system 1 in the present embodiment.

  The server device 11 includes a product related information storage unit 111, a terminal purchase information storage unit 112, a server reception unit 113, a product information selection unit 114, a product information output unit 115, a purchase processing unit 116, a condition information change unit 117, and product evaluation information. A receiving unit 118 and a product related information updating unit 119 are provided.

  The terminal device 12 includes a terminal reception unit 121, a terminal transmission unit 122, a terminal reception unit 123, and a terminal output unit 124.

  The approval server 13 includes a purchase process reception unit 131, an approval unit 132, and a server instruction transmission unit 133.

  The product related information storage unit 111 constituting the server device 11 can store one or more product related information. The product related information includes product information and evaluation information. The product information is information about the product and includes product identification information for identifying the product. The evaluation information is information related to the evaluation of the product, and has an unexpected degree of the product and a satisfaction level of the product. Unexpectedness is information regarding the degree of unexpectedness of a product. The satisfaction level is information regarding the level of satisfaction of the product. Further, it is preferable that the product information also includes amount information indicating the amount of the product identified by the product identification information. In addition, the product information may include a genre indicating the type of product, a sales number indicating the number of items that can be sold, a priority indicating a degree that the seller wants to sell, and the like. In addition to the unexpectedness (also referred to as “surprise”) and satisfaction (also referred to as “good”), the evaluation information included in the product-related information may include anger. The anger level is a degree related to the anger of the purchased user.

  The terminal purchase information storage unit 112 can store one or more pieces of terminal purchase information. The terminal purchase information includes a user identifier for identifying the user and condition information. That is, the terminal purchase information is information for managing condition information for each user. The condition information is information relating to conditions for selecting product information, and is information relating to conditions relating to unexpectedness and satisfaction. One terminal purchase information may hold two or more pieces of condition information. In such a case, for example, one condition information among two or more condition information may be sequentially selected. Two or more terminal purchase information corresponding to the same user identifier may be stored. The timing at which the terminal purchase information is stored in the terminal purchase information storage unit 112 does not matter.

  For example, the server reception unit 113 receives an instruction to purchase a product from the terminal device 12. The purchase instruction may include, for example, a user identifier and condition information. In addition, the server reception unit 113 may receive a product purchase instruction from the approval server 13, for example. In addition, the server reception unit 113 may receive user reaction information having satisfaction from the terminal device 12, for example. The user reaction information is information indicating a user's reaction to one or more purchased products or one or more products proposed from the server device 11. The degree of satisfaction is information indicating the degree of satisfaction of one or more products by the user. In addition, the degree of satisfaction is indicated by, for example, an integer from 1 to 10, characters from A to E, or the like. The satisfaction level is different from the satisfaction level. The degree of satisfaction is the degree of satisfaction with respect to the product selection action in the product information selection unit 114, and the degree of satisfaction is the degree of satisfaction with the product selected by the product information selection unit 114. Moreover, it is suitable that user reaction information has a terminal purchase information identifier which identifies terminal purchase information. Further, the user reaction information may have a user identifier.

  The product information selection unit 114 acquires one or more product information from the product related information storage unit 111 for each user identifier. The merchandise information selection unit 114 sets one or more pieces of merchandise information paired with the unexpectedness and satisfaction satisfying the condition according to the condition indicated by the condition information paired with the user identifier included in the purchase instruction received by the server receiving unit 113. get. Here, “for each user identifier” may be considered for each terminal purchase information.

  In addition, the product information selection unit 114 has amount information that is paired with the unexpectedness and satisfaction that satisfy the condition indicated by the condition information, and that satisfies a predetermined condition for the amount information included in the condition information. It is preferable to acquire one or more pieces of product information from the product related information storage unit 111. In such a case, the product information selection unit 114 usually acquires one or more product information within the budget.

  In addition, the product information selection unit 114 pairs, for each user identifier, regularly (for example, once a month) with the unexpectedness and satisfaction satisfying the condition according to the condition indicated by the condition information paired with the user identifier. It is preferable to acquire one or more pieces of product information from the product related information storage unit 111.

  Further, the product information selection unit 114 changes at least temporarily the condition information included in the terminal purchase information corresponding to the user reaction information according to the degree of satisfaction of the user reaction information received by the server reception unit 113, and According to the conditions indicated by the changed condition information, it is preferable to acquire one or more pieces of product information from the product related information storage unit 111. More specifically, the merchandise information selection unit 114 determines whether or not the satisfaction level of the user reaction information received by the server reception unit 113 satisfies a predetermined condition. For example, the product information selection unit 114 does not satisfy the condition. If the degree of satisfaction is low, the condition information included in the terminal purchase information corresponding to the user identifier included in the user reaction information is changed at least temporarily, and the degree of unexpectedness that satisfies the condition according to the condition indicated by the changed condition information and One or more pieces of product information paired with the satisfaction level are acquired from the product related information storage unit 111. In such a case, the product information selection unit 114 stores conditions in advance. The merchandise information selection unit 114 may store the conditions in association with one or more user identifiers for each user or for each of two or more user groups, or store conditions common to all users in advance. May be. Note that, for example, the product information selection unit 114 changes the condition information at least temporarily according to the degree of satisfaction of the user with the recently purchased product or the like, and changes the changed condition information to the next product information. Use as an opportunity for selection. In addition, for example, the product information selection unit 114 changes the condition information at least temporarily according to the user's satisfaction degree of two or more items purchased at the latest two or more occasions. The condition information is used as an opportunity for selecting the next product information.

  The merchandise information selection unit 114 changes the condition information as follows, for example, according to the satisfaction level. The first specific example of changing the condition information is as follows. That is, the merchandise information selection unit 114 has a condition in which the satisfaction level of the user reaction information is determined in advance (for example, when the satisfaction level can take any integer from 1 to 10, “satisfaction level> = 5”). When it is determined that the condition is not satisfied, the condition information corresponding to the terminal purchase information identifier included in the user reaction information is read from the terminal purchase information storage unit 112. And the merchandise information selection part 114 judges whether the said terminal purchase information gives priority to satisfaction or unexpectedness from the read condition information. That is, for example, if the product information selection unit 114 is “minimum satisfaction level included in condition information> minimum unexpected level included in condition information”, the terminal purchase information gives priority to satisfaction. If it is determined that “the minimum value of satisfaction included in the condition information <= the minimum value of unexpectedness included in the condition information”, it is determined that the terminal purchase information prioritizes the unexpectedness. Next, the product information selection unit 114 temporarily changes the condition information so as to select a product with a higher degree of satisfaction with respect to terminal purchase information in which satisfaction is prioritized. In addition, the product information selection unit 114 temporarily changes the condition information so as to select a product with a higher degree of surprise for terminal purchase information in which the degree of surprise is prioritized. Furthermore, the second specific example of changing the condition information is as follows. The merchandise information selection unit 114 determines whether the terminal purchase information prioritizes satisfaction or unexpectedness according to the same determination method as described above. Next, the product information selection unit 114 temporarily changes the condition information so as to select a highly unexpected product for the terminal purchase information that gives priority to satisfaction. In addition, the product information selection unit 114 temporarily changes the condition information so as to select a product with a high degree of satisfaction for the terminal purchase information in which the unexpectedness is prioritized. The merchandise information selection unit 114 may change the condition information in any way according to the degree of satisfaction.

  The product information output unit 115 outputs one or more product information selected by the product information selection unit 114 for each user identifier. The output here is usually transmission to the terminal device 12 corresponding to the user identifier. Note that output refers to display on a display, projection using a projector, printing on a printer, sound output, storage on a recording medium, output to another processing apparatus or another program (for example, the purchase processing unit 116), and the like. There may also be cases where processing results are delivered. Here, “for each user identifier” may be considered for each terminal purchase information.

  The purchase processing unit 116 performs a purchase process on one or more pieces of product information selected by the product information selection unit 114. Here, the purchase process is a process of transmitting one or more pieces of product information to the approval server 13, for example. Further, the purchase process may be a process of transmitting one or more pieces of product information to a server that manages the purchased product. The purchase process may be a process for printing a purchase slip. That is, the purchase process may be a process related to purchase.

  The condition information changing unit 117 changes the condition information included in the terminal purchase information according to the degree of surprise and the degree of satisfaction corresponding to one or more product information that is the target of the purchase processing performed by the purchase processing unit 116. The change of the condition information may be temporary.

  In the terminal purchase information storage unit 112, when one terminal purchase information includes two or more condition information, the condition information changing unit 117 uses a predetermined algorithm among the two or more condition information, One condition information may be selected, and a flag that can identify condition information to be used next may be written in the terminal purchase information storage unit 112. For example, when one terminal purchase information includes two pieces of condition information, the condition information changing unit 117 is configured so that the second condition information is used after the first condition information is used. A flag that can identify the condition information to be used next is written in the terminal purchase information storage unit 112.

  In addition, for example, the condition information changing unit 117 indicates that the information indicating the degree of surprise and the degree of satisfaction corresponding to one or more pieces of product information for which the purchase processing unit 116 has performed the purchase process is so large that the degree of unexpectedness satisfies the condition. In this case, the condition information of the terminal purchase information storage unit 112 is changed so as to increase the satisfaction level, and the unexpectedness and the satisfaction level corresponding to one or more pieces of product information for which the purchase processing unit 116 has performed the purchase process. If the degree of satisfaction is large enough to satisfy the condition, the condition information in the terminal purchase information storage unit 112 is changed so as to increase the degree of surprise. In such a case, the condition information changing unit 117 changes the condition information so as to purchase a safe product with a high degree of satisfaction after purchasing a highly unexpected product. On the other hand, the condition information changing unit 117 changes the condition information so as to purchase a highly unexpected product after purchasing a safe product with a high degree of satisfaction. The terminal purchase information here is terminal purchase information corresponding to the terminal purchase information identifier or the user identifier.

  The condition information changing unit 117 may change the condition information according to the purchase history of the product twice or more. That is, for example, when a product with a satisfaction level smaller than the threshold value is purchased twice in succession, the condition information changing unit 117 may change the condition information to a condition where the unexpected degree is equal to or higher than the threshold value.

  The product evaluation information receiving unit 118 receives product evaluation information from the terminal device 12. The product evaluation information includes product identification information, an unexpected degree, and a satisfaction level. Further, the product evaluation information may include product identification information, an unexpected level, a satisfaction level, and an anger level. Further, the product evaluation information may include other evaluation information.

  The product related information update unit 119 reflects the product evaluation information received by the product evaluation information receiving unit 118 in the product related information in the product related information storage unit 111. That is, the product related information update unit 119 may simply add the product evaluation information received by the product evaluation information receiving unit 118 to the product related information storage unit 111, or each evaluation information (exception, satisfaction, The average value of the anger level and the like is added to each evaluation information included in the product evaluation information received by the product evaluation information receiving unit 118 and recalculated, and the calculated average value of each evaluation information is calculated as the product identification information. Alternatively, the product related information storage unit 111 may accumulate the information. When the product related information storage unit 111 exists in an external device (product related information management server), the product related information update unit 119 receives the product evaluation information reception unit 118 from the product related information management server. The product evaluation information is used to instruct to change the product related information.

  The terminal accepting unit 121 constituting the terminal device 12 accepts a purchase instruction having a user identifier and condition information. The user identifier here may be stored in the terminal device 12 in advance. Further, the terminal receiving unit 121 may receive product evaluation information having product identification information, unexpectedness, and satisfaction. In addition, the terminal reception unit 121 may receive user reaction information having satisfaction. The user reaction information may include a terminal purchase information identifier for identifying terminal purchase information and a user identifier. And the terminal reception part 121 may read a terminal purchase information identifier from a recording medium, and may receive satisfaction from a keyboard, a mouse | mouth, etc. In other words, here, reception means reception of information input from an input device such as a keyboard, mouse, touch panel, reception of information transmitted via a wired or wireless communication line, an optical disk, a magnetic disk, a semiconductor memory, etc. This is a concept including reception of information read from the recording medium. The means for inputting purchase instructions and product evaluation information may be anything such as a keyboard, mouse, or menu screen. The terminal reception unit 121 can be realized by a device driver of an input unit such as a keyboard, menu screen control software, or the like.

  The terminal transmission unit 122 transmits a purchase instruction, product evaluation information, user reaction information, or the like to the server device 11. Further, it is preferable that the terminal transmission unit 122 also transmits the user identifier to the server device 11. In addition, the terminal transmission unit 122 may transmit a purchase instruction including a user identifier and condition information to the approval server 13.

  The terminal receiving unit 123 receives one or more product information from the server device 11. Here, the terminal reception unit 123 receives one or more pieces of product information transmitted by the product information output unit 115.

  The terminal output unit 124 outputs one or more product information received by the terminal receiving unit 123. The product information output here is product information of the purchased product. The terminal output unit 124 may be considered as including or not including an output device such as a display or a speaker. The terminal output unit 124 may be realized by output device driver software, or output device driver software and an output device.

  The purchase process reception unit 131 constituting the approval server 13 receives a user identifier and one or more product information. The purchase processing reception unit 131 may receive only the user identifier and information on the total amount of purchased products. The purchase process receiving unit 131 may receive information necessary for making a decision. The purchase process reception unit 131 may receive a purchase instruction having a user identifier and condition information from the terminal device 12.

  The approval unit 132 performs an approval process using the user identifier received by the purchase processing reception unit 131 and one or more product information. Since the approval process is a known technique, a detailed description thereof will be omitted.

  The server instruction transmission unit 133 transmits a purchase instruction to the server device 11. The purchase instruction usually includes a user identifier. The purchase instruction may include amount information, for example. It is preferable that the server instruction transmission unit 133 periodically transmits a purchase instruction to the server device 11 for each user identifier.

  The product related information storage unit 111 and the terminal purchase information storage unit 112 are preferably non-volatile recording media, but can also be realized by volatile recording media. The process in which product related information etc. are memorize | stored in the product related information storage part 111 grade | etc., Is not ask | required. For example, the product related information or the like may be stored in the product related information storage unit 111 or the like via a recording medium, and the product related information or the like transmitted via a communication line or the like may be stored in the product related information storage unit 111. The product related information input via the input device or the like may be stored in the product related information storage unit 111 or the like.

  The server receiving unit 113, the product evaluation information receiving unit 118, the terminal receiving unit 123, and the purchase processing receiving unit 131 are usually realized by wireless or wired communication means, but may be realized by means for receiving broadcasts. .

  The product information selection unit 114, the purchase processing unit 116, the condition information change unit 117, the product related information update unit 119, and the decision unit 132 can be usually realized by an MPU, a memory, or the like.

  Next, the operation of the information system 1 will be described. First, operation | movement of the server apparatus 11 is demonstrated using the flowchart of FIG.

  (Step S301) The server device 11 determines whether or not it is the timing for starting the product selection. If it is the product selection start timing, the process goes to step S302, and if it is not the product selection start timing, the process goes to step S307. Here, when the server reception unit 113 receives an instruction to start product selection from the terminal device 12 or the approval server 13, it may be determined that it is the timing for starting product selection. Further, when the product information selection unit 114 determines that it is a time that matches a predetermined condition, it may be determined that it is the timing for starting the product selection. That is, the timing for starting the product selection is not limited. Further, it is assumed that a user identifier for identifying a user corresponding to the product selection has been acquired at this stage. For example, the product selection start instruction has a user identifier. Further, for example, the product information selection unit 114 reads the user identifier when determining that it is the timing for starting the product selection.

  (Step S302) The product information selection unit 114 selects product information from the product related information storage unit 111, and acquires one or more product information. Such processing is called product selection processing. The product selection process will be described using the flowchart of FIG. A user identifier is passed to the product selection process.

  (Step S303) The purchase processing unit 116 performs a purchase process on the one or more pieces of product information acquired in Step S302.

  (Step S304) The product information output unit 115 transmits the one or more product information acquired in Step S302 to the terminal device 12.

  (Step S305) The condition information changing unit 117 configures new condition information. For example, it is assumed that the condition information changing unit 117 stores a condition 1 that places importance on satisfaction and a condition 2 that places importance on unexpectedness. If the condition information used in step S302 is condition 1, the condition information changing unit 117 acquires condition 2. If the condition information used in step S302 is condition 2, the condition information changing unit 117 acquires condition 1. The condition 1 is, for example, “satisfaction> = 7 (7 out of 10 points)”, “satisfaction> = 7 AND unexpected degree <= 3 (3 out of 10 points)”, or the like. The condition 2 is, for example, “unexpected degree> = 8” or “unexpected degree> = 8 AND satisfaction degree == 4”. In such a case, the purchase behavior emphasizing unexpectedness and the purchase behavior emphasizing satisfaction are alternately repeated, and the user satisfaction can be improved as a whole.

  (Step S306) The condition information changing unit 117 sets the condition information acquired in step S305 as the next condition information. The process returns to step S301.

  (Step S307) The product evaluation information receiving unit 118 determines whether or not product evaluation information is received from the terminal device 12. If the product evaluation information is received, the process goes to step S308, and if not received, the process goes to step S312.

  (Step S308) The product related information update unit 119 forms new product related information using the product evaluation information received in step S307.

  (Step S309) The product related information update unit 119 overwrites the new product related information configured in step S308 with the old product related information, and changes the product related information.

  (Step S310) The condition information changing unit 117 configures new condition information based on the product evaluation information received in Step S307. For example, if the degree of satisfaction of the product evaluation information received in step S307 is lower than a threshold, condition information with a high degree of satisfaction (for example, condition 1 described above) is configured. For example, if the unexpectedness degree which the merchandise evaluation information received by step S307 has is lower than a threshold value, condition information (for example, the above-mentioned condition 2) with a high unexpectedness degree will be comprised. The process returns to step S301.

  (Step S311) The condition information changing unit 117 accumulates the condition information configured in step S310 in the condition information area corresponding to the user identifier. The condition information changing unit 117 accumulates the condition information in the terminal purchase information storage unit 112.

  (Step S <b> 312) The server reception unit 113 determines whether user response information having satisfaction is received from the terminal device 12. If the user reaction information is received, the process goes to step S313, and if the user reaction information is not received, the process returns to step S301.

  (Step S313) The merchandise information selection unit 114 acquires the degree of satisfaction that the user reaction information received in Step S312 has. Here, the product information selection unit 114 may also acquire one or more past satisfaction levels stored in a recording medium (not shown). Note that the past satisfaction level of one or more is a past satisfaction level for the same terminal purchase information as the satisfaction level for the terminal purchase information corresponding to the received user reaction information.

  (Step S314) The merchandise information selection unit 114 reads the pre-stored conditions relating to the satisfaction level, and determines whether one or more satisfaction levels acquired in Step S313 satisfy the condition. If the condition is not satisfied, the process goes to step S315, and if the condition is satisfied, the process returns to step S301.

  (Step S315) The merchandise information selection unit 114 reads out condition information corresponding to the user reaction information received in step S312 from the terminal purchase information storage unit 112. And the merchandise information selection part 114 changes the said condition information with a predetermined algorithm, and produces | generates new condition information. Next, the merchandise information selection unit 114 temporarily stores the generated new condition information in association with the user identifier. Note that the recording medium in which the new condition information is stored is the terminal purchase information storage unit 112, but is normally not overwritten on the condition information set by the user. The process returns to step S301.

  In the flowchart of FIG. 3, the process ends when the power is turned off or the process is terminated.

  Next, the product selection process in step S302 will be described using the flowchart of FIG.

  (Step S401) The product information selection unit 114 reads out the condition information corresponding to the user identifier from the terminal purchase information storage unit 112. In this step, the product information selection unit 114 determines whether or not the condition information temporarily stored in step S315 exists, and when the condition information temporarily exists, it is preferable to read the condition information. It is. Moreover, it is suitable for the merchandise information selection part 114 to delete the temporary condition information once used. Further, the merchandise information selection unit 114 holds a condition for deleting the temporary condition information, and even if the condition information of one or more matches the deletion condition, the temporary condition information may be deleted. good.

  (Step S402) The merchandise information selection unit 114 substitutes 1 for a counter i.

  (Step S403) The product information selection unit 114 determines whether or not the i-th product related information exists in the product related information storage unit 111. If the i-th product related information exists, the process returns to step S404.

  (Step S404) The product information selection unit 114 reads the i-th product related information from the product related information storage unit 111.

  (Step S405) The product information selection unit 114 acquires evaluation information such as an unexpected degree and a satisfaction level included in the i th product related information. Here, the information acquired by the product information selection unit 114 is evaluation information related to the condition information.

  (Step S406) The merchandise information selection unit 114 determines whether or not the unexpectedness degree and the satisfaction degree acquired in step S405 match the condition information read in step S401. If they match, go to step S407, and if they do not match, go to step S413.

  (Step S407) The merchandise information selection unit 114 acquires amount information included in the i-th merchandise related information.

  (Step S408) The merchandise information selection unit 114 determines whether or not the amount information acquired in step S407 matches the condition information. If they match, go to step S409, and if not, go to step S413.
