Modes for Carrying Out the Invention

[0017] Hereinafter, the present invention will be described through embodiments of the invention. However, the following embodiments do not limit the invention according to the claims. Also, not all combinations of the features described in the embodiments are essential for the solution means of the invention. In the drawings, the same or similar parts may be given the same reference numerals, and duplicate descriptions may be omitted.

[0018] [Overview of the Transaction Management System 100] FIG. 1 schematically shows an example of the system configuration of the transaction management system 100. In the present embodiment, the transaction management system 100 includes, for example, a management server 110. In the present embodiment, the management server 110 has, for example, a transaction management unit 112 and a distribution management unit 114.

[0019] The transaction management system 100 may further include at least one of a production robot 120, a fruit selection system 140, and a logistics system 160. In the present embodiment, the production robot 120 has, for example, a base unit 130, one or more (which may sometimes be simply referred to as one or more) moving units 132, one or more imaging units 134, one or more sensor units 136, and one or more work units 138.

[0020] In the present embodiment, the details of the transaction management system 100 will be described by taking as an example the case where the transaction management system 100 manages the transactions of products 12 and 14. In the present embodiment, the details of the transaction management system 100 will be described by taking as an example the case where the product 14 is an article of the same or similar type as the product 12, or an article produced by the producer 20 of the product 12.

[0021] Also, in the present embodiment, the details of the transaction management system 100 will be described by taking as an example the case where the products 12 and 14 are (i) fresh foodstuffs or (ii) agricultural products, fishery products, or livestock products. Examples of fresh foodstuffs include fruits and vegetables, fresh flowers, seafood, and meat. Examples of agricultural products include grains, vegetables, fruits, tea, flowers and trees, mushrooms, or hyphae. However, the products 12 and 14 are not limited to fresh foodstuffs, agricultural products, fishery products, or livestock products.

[0022] In the transaction of product 12 and product 14, producer 20 produces product 12 and product 14. Producer 20 transfers produced product 12 and product 14 to consumer 40, with or without compensation. Producer 20 may transfer product 12 and product 14 to consumer 40 via one or more distributors 30. In this case, for example, first, producer 20 transfers product 12 and product 14 to distributor 30, with or without compensation. Next, distributor 30 transfers product 12 and product 14 to consumer 40, with or without compensation.

[0023] In this embodiment, the producer 20 performs various tasks to produce the product 12 and the product 14. The producer 20 may be a natural person or an organization. The organization may or may not have legal personality. The producer 20 may access the management server 110 using a communication terminal 22. The producer 20 may use, for example, the communication terminal 22 to transmit information indicating a record of various tasks related to the product 12 and the product 14 to the management server 110. The producer 20 may use a production robot 120 to produce the product 12 and the product 14.

[0024] In this embodiment, the distributor 30 mediates transactions between the producers 20 and the consumers 40. Examples of the distributor 30 include transport companies, warehouse operators, wholesalers, and retailers. A producer group consisting of multiple producers 20 may have an aspect as a distributor 30 in addition to an aspect as a producer 20. Examples of the producer group include a collection and shipping group and a cooperative.

[0025] In this embodiment, the consumer 40 receives the product 12 and the product 14 from the producer 20 or the distributor 30, with or without payment. The consumer 40 uses or consumes the product 12 and the product 14. The consumer 40 may inspect or evaluate the product 12 and the product 14 before using or consuming the product 12 and the product 14. The consumer 40 may inspect or evaluate the product 12 and the product 14 after using or consuming the product 12 and the product 14.

[0026] [Overview of Information Processing in Transaction Management System 100] Taking as an example the case where consumer 46, which is another example of consumer 40, purchases product 14 after consumer 44, which is an example of consumer 40, purchases product 12, an example of information processing in transaction management system 100 will be described. In the present embodiment, transaction management system 100 collects various data in the transaction process of product 12. Transaction management system 100 may execute a process for assisting in the collection of the above data.

[0027] Various data collected in the transaction of product 12 are used in the transaction of product 14. In one embodiment, transaction management system 100 executes a process for presenting to consumer 46, who is considering purchasing product 14, data regarding the evaluation of product 12 or producer 20 collected in the transaction of product 12 (which may simply be referred to as evaluation information regarding product 12). In other embodiments, transaction management system 100 executes a process for determining the selling points of product 14 based on the characteristics of product 14 that are the subject of current or future transactions and the evaluation of product 12. Also, transaction management system 100 executes a process for notifying consumer 46, who is likely to be interested in the selling points of product 14, of sales promotion information for product 14.

[0028] Evaluation information regarding a product (which may simply be referred to as product evaluation information) may be information indicating the type and quality of the product. For example, the product evaluation information includes information indicating the type of the product and information indicating the evaluation of the product. The product evaluation information may be information in which the type of the product and the evaluation of the product are associated. The type of the product may be identified by the item of the product. The item of the product may be the name of the type of the product. The evaluation of the product may be an evaluation of the quality of the product. The quality of the product is determined based on, for example, various characteristics regarding the product. According to the present embodiment, since transaction management system 100 acquires evaluation information regarding product 12 at a plurality of time points in the transaction process of product 12, the quality of product 12 at the production time or the shipping time can be evaluated more accurately.

[0029] Producer 20 may be evaluated based on the evaluation of product 12, or may be evaluated based on the evaluation of producer 20. In this embodiment, for the purpose of simplifying the description, the details of the information processing in transaction management system 100 will be described by taking the case where consumer 44 evaluates product 12 as an example.

[0030] In this embodiment, transaction management system 100 acquires evaluation information regarding product 12 at a plurality of time points in the transaction process of product 12. For example, transaction management system 100 acquires evaluation information regarding product 12 at least at one of the inspection time point or evaluation time point of product 12, the production time point or shipping time point of product 12, and a specific time point in the distribution process of product 12.

[0031] In particular, fresh food, agricultural products, fishery products, livestock products, etc. are more likely to deteriorate in quality compared to, for example, industrial products.

For example, consumer 46 views the evaluation of product 14 included in the above product description screen and considers purchasing product 14. In still other embodiments, a consumer 40 who is a potential customer of product 14 receives various notifications from the transaction management system 100. For example, consumer 40 obtains information regarding product 14 based on the above notifications. The information regarding product 14 includes, for example, information regarding the evaluation of product 14. Consumer 40 considers purchasing product 14, for example, with reference to the evaluation of product 14.

[0125] In this embodiment, the user information acquisition unit 442 acquires various types of information regarding the users of the transaction management system 100. For example, the user information acquisition unit 442 acquires information indicating the respective behavioral characteristics (which may be referred to as competencies) of one or more users, interests, or preferences (which may be referred to as user information). The behavioral characteristics indicate, for example, patterns of behavior, thinking, attitude, etc. (which may be referred to as behavior patterns) that each user characteristically has. The behavioral characteristics may be information indicating in what situations each user takes what actions, thinking, or attitude. The behavioral characteristics may be information in which the situations in which the user is placed are associated with the user's actions, thinking, or attitude in those situations.

[0126] In one embodiment, with the consent of each user, the user information acquisition unit 442 acquires, as user information, the usage history of the EC site operated by the EC site management unit 422. Examples of the usage history of the EC site include a search history, a browsing history, a purchase history, etc. In other embodiments, with the consent of each user, the user information acquisition unit 442 acquires, as user information, (i) the browsing history of a website and / or (ii) the search history of a website or keyword recorded in the communication terminal used by each user.

[0127] Note that the user information may include various types of information other than the information indicating the behavioral characteristics, interests, or preferences of each user. For example, the user information may include information regarding the location of the place where each user produces goods (which may be referred to as the production site), the region to which the production site belongs, etc.

[0128] The user information acquisition unit 442 may analyze the usage history of the EC site, the browsing history of the website, the search history of the website or keyword, etc., and estimate the behavioral characteristics, interests, and / or preferences of each user. The user information acquisition unit 442 may acquire, as user information, information indicating the estimation results of the behavioral characteristics, interests, and / or preferences.

[0129] In this embodiment, the user information storage unit 444 stores the user information acquired by the user information acquisition unit 442. For example, the user information storage unit 444 stores, for each of one or more users, identification information for identifying the user and the user information of the user in association with each other. The user information storage unit 444 may extract the user information of the user that matches the request in response to a request from the sales management unit 420 and / or the evaluation management unit 460. The user information storage unit 444 may output the extracted user information to the sales management unit 420 and / or the evaluation management unit 460.

[0130] In this embodiment, the evaluation management unit 460 manages the evaluation for each of one or more products. The evaluation management unit 460 manages the acquisition of the evaluation for each of one or more products. The evaluation management unit 460 manages the use of the evaluation for each of one or more products.

[0131] In this embodiment, the evaluation acquisition unit 462 manages information regarding the evaluation for each of one or more products. In one embodiment, the evaluation acquisition unit 462 acquires information regarding the evaluation for each of one or more products. In other embodiments, the evaluation acquisition unit 462 generates various types of information using the information regarding the evaluation for each of one or more products. The details of the evaluation acquisition unit 462 will be described later.

[0132] In this embodiment, the evaluation correction unit 464 corrects the evaluation for each of one or more products acquired by the evaluation acquisition unit 462. For example, when there is a large difference between the state of the product at the time of production or shipment and the state of the product at the time of inspection or evaluation, the evaluation by the consumer 40 may not accurately represent the state of the product.

[0133] Therefore, in this embodiment, the evaluation correction unit 464 corrects the evaluation by the consumer 40. For example, when the consumer 44 evaluates the product 12 that has been traded in the past, the evaluation acquisition unit 462 acquires the demand-side evaluation information indicating the evaluation of the product 12 by the consumer 44. The evaluation acquisition unit 462 acquires the demand-side evaluation information from the evaluation acquisition unit 462. As described above, the demand-side evaluation information includes information indicating the results of evaluations for one or more evaluation items related to the product 12.

[0134] In addition, the evaluation correction unit 464 acquires the distribution status information and the distribution period information from the distribution management unit 114. As described above, examples of the distribution status information include information indicating the characteristics of the product 12 in the distribution process and information indicating the state of the distribution environment of the product 12. The evaluation correction unit 464 may acquire production information and / or inspection information. The evaluation correction unit 464 may calculate the length of the distribution period based on the production information and the inspection information.

[0135] The evaluation correction unit 464 corrects the evaluation results for at least one of one or more evaluation items (for example, P evaluation items) related to the product 12 indicated by the demand-side evaluation information acquired by the evaluation acquisition unit 462. The evaluation correction unit 464 may correct the evaluation results for at least one of one or more evaluation items related to the product 12 based on the inspection date or the evaluation date of the product 12 indicated by the inspection information. The evaluation correction unit 464 may correct the evaluation results for at least one of one or more evaluation items related to the product 12 based on the length of the distribution period.

[0136] For example, when at least one of the state of the product 12 in the distribution process indicated by the above-described distribution status information and the length of the distribution period indicated by the distribution period information does not meet a predetermined condition, the evaluation correction unit 464 corrects the evaluation results for at least one of one or more evaluation items related to the product 12 indicated by the demand-side evaluation information acquired by the evaluation acquisition unit 462. Examples of the above-described predetermined conditions include the condition that the state of the product 12 in the distribution process is worse than a predetermined state and the condition that the length of the distribution period is greater than a predetermined value.

[0137] The evaluation correction unit 464 corrects the evaluation result for at least one of one or more evaluation items regarding the product 12 indicated by the demand-side evaluation information acquired by the evaluation acquisition unit 462, based on at least one selected from the group consisting of, for example, (i) at least one of the origin and item of the product 12, (ii) the state of the product 12 in at least a part of the distribution process of the product 12, and (iii) the length of the period indicated by the distribution period information. The evaluation correction unit 464 may correct the evaluation result for at least one of one or more evaluation items regarding the product 12 indicated by the demand-side evaluation information acquired by the evaluation acquisition unit 462, based on (a) at least one of the origin and item of the product 12 and (b) at least one of the state of the product 12 in at least a part of the distribution process of the product 12 and the length of the period indicated by the distribution period information.

[0138] For example, when the product 12 is a fresh food, agricultural product, fishery product, or livestock product, depending on the origin and / or item of the product 12, the quality may be more likely to deteriorate compared to when the product 12 has other origins and / or items. Therefore, when the origin of the product 12 is a predetermined origin, the evaluation correction unit 464 may correct the evaluation result so that the evaluation for the predetermined evaluation item is better than the evaluation by the consumer 44. When the item of the product 12 is a predetermined item, the evaluation correction unit 464 may correct the evaluation result so that the evaluation for a specific evaluation item is better than the evaluation by the consumer 44.

[0139] The above specific evaluation item may be determined based on the origin or item of the product 12. A correspondence relationship between the origin or item of the product 12 and the evaluation item to be corrected may be predetermined.

[0140] For example, when the state of product 12 is poor in at least a part of the distribution process of product 12, the quality of product 12 is likely to deteriorate. In particular, depending on the origin or item of product 12, when the state of product 12 is poor in at least a part of the distribution process of product 12, the quality of product 12 will deteriorate significantly. Also, it is expected that the degree of deterioration of the quality of product 12 will increase as the state of product 12 in the distribution process becomes worse. Therefore, the evaluation correction unit 464 may correct the evaluation result so that the evaluation for a specific evaluation item becomes better than the evaluation by the consumer 44 as the state of product 12 in the distribution process becomes worse.

[0141] The above specific evaluation item may be determined based on the origin or item of product 12. A correspondence relationship between the origin or item of product 12 and the evaluation item to be corrected may be predetermined. The above specific evaluation item may also be determined based on the matters that were poor in the distribution process among the states of product 12. A correspondence relationship between the matters representing the state of product 12 and the evaluation item to be corrected may be predetermined.

[0142] For example, when the distribution period of product 12 is long, the quality of product 12 is likely to deteriorate. In particular, depending on the origin or item of product 12, when the distribution period of product 12 is long, the quality of product 12 will deteriorate significantly. Also, it is expected that the degree of deterioration of the quality of product 12 will increase as the distribution period of product 12 becomes longer. Therefore, the evaluation correction unit 464 may correct the evaluation result so that the evaluation for a specific evaluation item becomes better than the evaluation by the consumer 44 as the distribution period of product 12 becomes longer.

[0143] The above specific evaluation item may be determined based on the origin or item of product 12. A correspondence relationship between the origin or item of product 12 and the evaluation item to be corrected may be predetermined. The above specific evaluation item may also be determined based on the length of the distribution period of product 12. A correspondence relationship between the length of the distribution period and the evaluation item to be corrected may be predetermined.

[0144] The evaluation correction unit 464 may store information indicating the corrected evaluation result in the evaluation information storage unit 466 as an evaluation of product 12. If the state of product 12 or the length of the distribution period in the distribution process meets the above-mentioned predetermined conditions, the evaluation acquisition unit 462 may store the demand-side evaluation information indicating the evaluation of product 12 by the consumer 44 in the evaluation information storage unit 466 as an evaluation of product 12.

[0145] The sales management unit 420 may be an example of a management device. The EC site management unit 422 may be an example of a management device. The user information acquisition unit 442 may be an example of a viewer information acquisition unit or a receiver information acquisition unit.

The user information may be an example of viewer information or receiver information. The evaluation management unit 460 may be an example of a management device or a support unit. The evaluation acquisition unit 462 may be an example of a management device or a support unit. The evaluation correction unit 464 may be an example of a correction unit. The evaluation information storage unit 466 may be an example of an evaluation storage unit.

[0146] FIG. 5 schematically shows an example of a product description screen of a product on sale. Using FIG. 5, an example of the generation process of the product description screen by the EC site management unit 422 will be described. In the present embodiment, the EC site management unit 422 adjusts the content displayed on the product description screen according to the behavior characteristics, interests, or preferences of the viewer. For example, the EC site management unit 422 determines the evaluation items used for evaluating the product on the product description screen according to the behavior characteristics, interests, or preferences of the viewer.

[0147] As described above, the evaluation items used for evaluating the product can be classified into a plurality of evaluation categories. The EC site management unit 422 may determine the above-mentioned evaluation items by determining the evaluation category used for evaluating the product on the product description screen according to the behavior characteristics, interests, or preferences of the viewer. The EC site management unit 422 may determine the evaluation category and the evaluation items according to the behavior characteristics, interests, or preferences of the viewer.

[0148] In FIG. 5, the product description screen 540 shows an example of the product description screen of product 14 when the first consumer 40 views the EC site. Similarly, the product description screen 560 shows an example of the product description screen of product 14 when the second consumer 40 views the EC site.

The product evaluation image 546 includes, for example, the evaluation value of product 14 (which may be referred to as a comprehensive score in some cases) when product 14 is comprehensively evaluated using evaluation categories H, B, J, K, D, and F.

[0153] In the product evaluation images 546 and 566, the evaluation items for deriving the evaluation values of each evaluation category may be calculated based on the evaluation values of all the evaluation items constituting each evaluation category, or may be calculated based on the evaluation values of some of the evaluation items constituting each evaluation category. The above-mentioned some of the evaluation items may be determined based on at least one of the behavioral characteristics, interests, and preferences of the consumer 40 who views the product description screen.

[0154] In the product evaluation images 546 and 566, the arrangement of each evaluation category in the graph showing the characteristics of the product 14 may be determined (i) based on a predetermined rule, or (ii) based on at least one of the behavioral characteristics, interests, and preferences of the consumer 40 who views the product description screen. Examples of the predetermined rule include the order of the names of each evaluation category, the magnitude of the evaluation values of each evaluation category, and the like. The arrangement of each evaluation category in the graph showing the characteristics of the product 14 is determined, for example, based on the correspondence between the degree of conformity or the order of the degree of conformity with the behavioral characteristics, interests, and preferences of the consumer 40 who views the product description screen and the arrangement in the graph.

[0155] According to the present embodiment, the evaluation items used for evaluating the product on the product description screen are adjusted according to the behavioral characteristics, interests, or preferences of the user who views the product description screen.

[0160] On the other hand, the evaluation input screen 640 includes an input form 642 for inputting an evaluation regarding evaluation category A and an input form 644 for inputting an evaluation regarding evaluation category C. On the evaluation input screen 640, input fields for inputting evaluation items Aa, Ad, and Af are arranged in the input form 642. Similarly, input fields for inputting evaluation items Ca, Cb, and Cc are arranged in the input form 644. Examples of the input fields include a text field, a text area, a checkbox, a radio button, and a pull-down box.

[0161] In the present embodiment, the evaluation input screen 640 is different from the evaluation input screen 620 in that it does not include an input form for inputting an evaluation regarding evaluation category B. Also, the input form 642 for inputting an evaluation regarding evaluation category A on the evaluation input screen 640 is different from the input form 622 for inputting an evaluation regarding evaluation category A on the evaluation input screen 620 in that input fields for inputting evaluation items Ad and Af are arranged instead of input fields for inputting evaluation items Ab and Ac.

[0162] According to the present embodiment, the evaluation items displayed on the evaluation input screen are adjusted according to the state or the length of the distribution period in the distribution process of the product to be evaluated. Thereby, the burden on the user's input is reduced. Also, since input / output of unnecessary data is suppressed, the load on the management server 110 is reduced.

[0163] FIG. 7 schematically shows another example of the evaluation input screen for the product after delivery is completed. In FIG. 7, the evaluation input screen 740 shows an example of the evaluation input screen presented to the consumer 44 for inputting an evaluation of the product 12 when the state of the product 12 in the distribution process is not good.

[0164] In this embodiment, the evaluation input screen 740 is different from the evaluation input screen 640 in that it includes an input form 744 for inputting an evaluation regarding evaluation category B. In this embodiment, a message 750 indicating that it is not necessary to input an evaluation regarding evaluation category B is displayed in the input form 744. A message 750 indicating the reason why it is not necessary to input an evaluation regarding evaluation category B may be displayed in the input form 744.

[0165] FIG. 8 schematically shows an example of the internal configuration of the EC site management unit 422. As described above, in this embodiment, an example of the EC site management unit 422 is described by taking as an example the case where the EC site management unit 422 uses various data collected in the transaction of product 12 in the transaction of product 14. In this embodiment, for the purpose of simplifying the explanation, the details of each part of the EC site management unit 422 are described by taking as an example the case where the item and producer of product 12 are the same as the item and producer of product 14. As described above, the relationship between product 12 and product 14 is not limited to this embodiment.

[0166] In this embodiment, the EC site management unit 422 includes a transaction support unit 820, a matching support unit 840, and a data transmission unit 860. In this embodiment, the transaction support unit 820 includes an evaluation information extraction unit 822, a user information extraction unit 824, a first item determination unit 826, a first item evaluation unit 828, a product evaluation unit 830, and a transaction screen generation unit 832. In this embodiment, the matching support unit 840 includes a second item evaluation unit 842, a second item determination unit 844, a recipient extraction unit 846, and a notification generation unit 848.

[0167] The transaction support department 820 supports the transaction of products on the EC site. For example, the transaction support department 820 generates screen data of various screens (which may be referred to as transaction screens) used for the transaction of products. Examples of transaction screens include a product search screen, a product description screen, a product purchase screen, a settlement screen, and the like. The transaction support department 820 may support the transaction of products by managing the evaluation of the products. For example, the transaction support department 820 generates screen data of a product description screen for presenting the evaluation of a product to a viewer.

[0168] In the present embodiment, the evaluation information extraction unit 822 acquires evaluation information regarding the product 12. For example, the evaluation information extraction unit 822 accesses the evaluation information storage unit 466 and extracts one or more pieces of evaluation information regarding one or more products 12 that have been transacted in the past. As described above, the evaluation information regarding the product 12 indicates the evaluation result for at least one of P (P is an integer of 2 or more) evaluation items regarding the product 12. Also, in the transaction management system 100, the P evaluation items are classified into a plurality of evaluation categories.

[0169] The user information extraction unit 824 acquires user information of a user who accesses the EC site. For example, the user information extraction unit 824 accesses the user information storage unit 444 and extracts user information regarding a user who accesses the EC site. As described above, the user information includes information indicating the behavior characteristics, interests, or preferences of the user.

[0170] In the present embodiment, the first item determination unit 826 determines Q (Q is a positive integer less than or equal to P) evaluation items used for generating the product description screen from among the P evaluation items regarding the product 12 based on the user information acquired by the user information extraction unit 824. For example, a correspondence relationship between at least one of the behavior characteristics, interests, and preferences of the user and the evaluation items used for generating the product description screen is predetermined. The first item determination unit 826 determines Q evaluation items used for generating the product description screen based on at least one of the behavior characteristics, interests, and preferences indicated by the user information acquired by the user information extraction unit 824 and the above correspondence relationship.

[0171] The Q evaluation items are used, for example, to derive the evaluation value of product 14 in generating the product description screen. The evaluation value of product 14 indicates the degree of evaluation of product 14. The evaluation value of product 14 may be expressed by continuous numerical values or by stepwise classification. The evaluation value of product 14 is used, for example, in generating the graph displayed in the product evaluation image 546 and / or calculating the overall score displayed in the product evaluation image 546 in the product description screen 540 described in relation to FIG. 5.

[0172] The first item determination unit 826 determines one or more evaluation categories used in generating the product description screen from among a plurality of evaluation categories based on at least one of the user's behavior characteristics, interests, and preferences indicated by the user information. For example, a correspondence relationship is predetermined between at least one of the user's behavior characteristics, interests, and preferences and the evaluation categories used in generating the product description screen. The first item determination unit 826 determines one or more evaluation categories used in generating the product description screen based on at least one of the behavior characteristics, interests, and preferences indicated by the user information acquired by the user information extraction unit 824 and the above correspondence relationship. Thereby, the evaluation categories used for presenting the evaluation to the user are determined.

[0173] Similarly, the first item determination unit 826 may determine one or more evaluation categories used in generating the product description screen from among a plurality of evaluation categories based on at least one selected from the group consisting of (i) the type of product 14, (ii) the user's instruction, and (iii) the behavior characteristics, interests, and preferences of the viewer indicated by the user information. Thereby, the evaluation categories used for presenting the evaluation to the user are determined.

[0174] For each of one or more evaluation categories used to generate the product description screen, the first item determination unit 826 may determine Q evaluation items by determining the evaluation items used to generate the product description screen among one or more evaluation items included in each evaluation category. The first item determination unit 826 may determine Q evaluation items including one or more evaluation items included in one or more evaluation categories based on at least one of the behavior characteristics, interests, and preferences of the user indicated by the user information.

[0175] In the present embodiment, the first item evaluation unit 828 calculates an evaluation value for each of the above Q evaluation items based on one or more evaluation information regarding the product 12 acquired by the evaluation information extraction unit 822. For example, the first item evaluation unit 828 calculates the evaluation value for each evaluation item by calculating the statistical value of the evaluation values of each evaluation item included in the one or more evaluation information. Examples of the statistical value include the average value and the median value. When the evaluation value of a specific evaluation item is expressed by a stepwise category in the one or more evaluation information, the first item evaluation unit 828 may calculate the above statistical value by replacing each category with a numerical value.

[0176] The first item evaluation unit 828 may calculate an evaluation value for each of one or more evaluation categories determined by the first item evaluation unit 828. For example, the first item evaluation unit 828 calculates the evaluation value for each evaluation category by calculating the statistical value of one or more evaluation items included in each evaluation category. Examples of the statistical value include the average value and the median value. When the evaluation value of a specific evaluation item is expressed by a stepwise category in the one or more evaluation categories, the first item evaluation unit 828 may calculate the above statistical value by replacing each category with a numerical value.

[0177] In the present embodiment, the product evaluation unit 830 calculates an overall evaluation value of the product 12 based on the evaluation value for each of the Q evaluation items calculated by the first item evaluation unit 828 and the weight assigned to each of the Q evaluation items. The overall score described in relation to FIG. 5 may be an example of the overall evaluation value of the product 12.

[0178] The product evaluation unit 830 may determine the weight values assigned to each of the Q items based on at least one of the user's behavioral characteristics, interests, and preferences indicated by the user information. For example, the product evaluation unit 830 may determine the weight values such that the weight value assigned to at least one of one or more items related to the user's behavioral characteristics, interests, and / or preferences is greater than that assigned to at least one of one or more items not related to the user's behavioral characteristics, interests, and / or preferences.

[0179] The product evaluation unit 830 may determine each weight value such that the greater the degree of the user's interests and / or preferences, the greater the weight value assigned to the item related to the interests and / or preferences. The product evaluation unit 830 may also determine each weight value such that the greater the tendency of the user to take a specific action, thinking, or attitude, the greater the weight value assigned to the item related to the specific action, thinking, or attitude.

[0180] For example, when product 12 is an agricultural product, the balance of flavors such as sourness and sweetness, texture, etc. varies depending on the variety. Therefore, the product evaluation unit 830 determines the weight values assigned to each of the Q items according to the user's preference for taste and / or texture. For example, the product evaluation unit 830 determines the weight values assigned to each of the Q items such that the item that matches the user's preference for taste and / or texture has a greater weight value.

[0181] More specifically, the product evaluation unit 830 determines the weight values assigned to each of the Q items based on the user's evaluation of the taste and / or texture of agricultural products that the user has traded in the past and that are of the same or similar variety as product 12. The product evaluation unit 830 may determine the weight values assigned to at least one of the Q items such that the higher the evaluation in the user's past evaluation, the greater the weight.

[0182] The product evaluation unit 830 may estimate the user's evaluation of the taste and / or texture of agricultural products of the same or similar varieties as product 12, and determine the weight values assigned to each of the Q items based on the estimated evaluation. For example, the product evaluation unit 830 determines the reference values of the evaluations for each variety based on the evaluations from a plurality of users for variety A and variety B. Also, the product evaluation unit 830 obtains the evaluation of user X for variety A. The product evaluation unit 830 estimates the evaluation of user X for variety B based on the evaluation of user X for variety A, the reference value of the evaluation for variety A, and the reference value of the evaluation for variety B.

[0183] For example, when product 12 is a strawberry of variety B and the evaluations of the sweetness of strawberries of variety A and variety B are represented on a 10-point scale from 0 to 9, and the evaluation of user X for the sweetness of variety A is 3 and the reference value of the evaluation for the sweetness of variety A is 5, the product evaluation unit 830 estimates that user X tends to evaluate the sweetness of strawberries low. Therefore, when the reference value of the evaluation for the sweetness of variety B strawberries is 8, the product evaluation unit 830 outputs a value smaller than 8 (for example, 5 to 6) as the estimated value of the evaluation of user X for the sweetness of variety A. Similarly, the product evaluation unit 830 estimates the evaluation of user X for each item related to taste and / or texture.

[0184] The product evaluation unit 830 determines the weight values assigned to each of the Q items such that, for example, the larger the estimated value of the evaluation of user X for each item related to taste and / or texture, the larger the weight value assigned to that item. The product evaluation unit 830 may also determine the weight values assigned to each of the Q items such that the greater the deviation between the estimated value of the evaluation of user X for each item related to taste and / or texture and a predetermined value, the larger the weight value assigned to that item. Thereby, the product evaluation unit 830 can assign values according to the preferences of the user as the weights of each item based on, for example, the evaluation history of agricultural products that the user has eaten or purchased in the past.

[0185] Similarly, the product evaluation unit 830 may determine the weight values assigned to each of the Q items based on the characteristics in the production process of the agricultural products purchased by the user in the past. For example, when the frequency of the user purchasing organic agricultural products is greater than a predetermined value, the product evaluation unit 830 determines the weight values assigned to each of the Q items such that the weight assigned to the item regarding the presence or amount of use of chemical fertilizers and / or pesticides in the production process increases.

[0186] The product evaluation unit 830 may also determine the weight values assigned to each of the Q items based on the use of product 12. For example, the required quality differs between strawberries for fresh consumption and strawberries for jam. For strawberries for fresh consumption, appearance quality, freshness, etc. are emphasized. On the other hand, for strawberries for jam, low price is emphasized. Therefore, the product evaluation unit 830 determines the weight values assigned to each of the Q items such that, for example, the weight value increases for the items emphasized in the use of product 12.

[0187] In this embodiment, the transaction screen generation unit 832 generates screen data for various transaction screens. The transaction screen generation unit 832 may generate data (sometimes referred to as screen data) for causing the communication terminal 42 of the consumer 46 to display a product description screen for explaining product 14. For example, the transaction screen generation unit 832 generates a product description screen 540 and a product description screen 560.

[0188] More specifically, the transaction screen generation unit 832 generates data for causing the communication terminal 42 to draw a graph showing the characteristics of the product 14 (i.e., the product 12) based on one or more evaluation categories determined by the first item determination unit 826 and the evaluation values of each evaluation category regarding the product 12 determined by the first item evaluation unit 828. Further, the transaction screen generation unit 832 generates data for causing the communication terminal 42 to draw the overall score of the product 14 (i.e., the product 12) based on the overall evaluation value of the product 12 determined by the product evaluation unit 830. As described above, each evaluation category regarding the product 12 is information related to Q evaluation items regarding the product 12, and the evaluation value of each evaluation category is information related to the evaluation value for each of the Q evaluation items.

[0189] In the present embodiment, the matching support unit 840 supports the transaction of the product 14 by matching the product 14 or the producer 20 with one or more users. For example, the matching support unit 840 extracts potential customers who match the characteristics of the product 14 or the producer 20 from among one or more users based on the demand-side evaluation information regarding the product 12 and / or the supply-side evaluation information regarding the product 14. The matching support unit 840 notifies the extracted users of the information regarding the product 14. The information regarding the product 14 may include information regarding the evaluation of the product 14.

[0190] As described above, in the present embodiment, an example of the matching support unit 840 is described by taking the case where the item and producer of the product 12 are the same as those of the product 14 as an example. Also, in the present embodiment, for the purpose of simplifying the explanation, an example of the matching support unit 840 is described by taking the case where the matching support unit 840 extracts potential customers who match the characteristics of the product 14 or the producer 20 from among one or more users based on the demand-side evaluation information regarding the product 12 as an example. As described above, the matching support unit 840 is not limited to the present embodiment.

[0191] In this embodiment, the second item evaluation unit 842 calculates an evaluation value for each of the P evaluation items regarding the product 12 based on one or more pieces of evaluation information regarding the product 12 acquired by the evaluation information extraction unit 822. The second item evaluation unit 842 may calculate an evaluation value for each of the P evaluation items regarding the product 12 in the same procedure as the first item evaluation unit 828.

[0192] In this embodiment, the second item determination unit 844 determines Q (Q is a positive integer less than or equal to P.) evaluation items to be used for determining the evaluation of the product 12 from among the P evaluation items based on the evaluation values for each of the P evaluation items calculated by the second item evaluation unit 842. The Q evaluation items are determined, for example, for the purpose of promoting the sale of the product 14.

[0193] In one embodiment, the second item determination unit 844 compares the evaluation values of each of the P evaluation items and determines Q evaluation items in descending order of the evaluation values. In another embodiment, the second item determination unit 844 determines Q evaluation items consisting of S (S is a positive integer greater than or equal to 1 and less than P.) evaluation items of a predetermined type and T (T is a positive integer calculated as P - S.) evaluation items selected based on the evaluation values calculated by the second item evaluation unit 842. T evaluation items may be determined in descending order of the evaluation values from among the evaluation items other than the S evaluation items.

[0194] In this embodiment, the receiver extraction unit 846 extracts users who can become customers of the product 14 from among one or more users who can receive information regarding the product 14. For example, the receiver extraction unit 846 refers to the user information storage unit 444 and extracts users who have behavioral characteristics, interests, or preferences related to the Q evaluation items determined by the second item determination unit 844. The receiver extraction unit 846 may refer to the user information storage unit 444 and extract users who do not have behavioral characteristics, interests, or preferences related to evaluation items other than the Q evaluation items determined by the second item determination unit 844. The receiver extraction unit 846 may refer to the user information storage unit 444 and extract users who (i) have behavioral characteristics, interests, or preferences related to the Q evaluation items determined by the second item determination unit 844 and (ii) do not have behavioral characteristics, interests, or preferences related to evaluation items other than the Q evaluation items determined by the second item determination unit 844.

[0195] For example, when comparing the product 14 with other products, if the evaluation of the appearance of the product 14 is low and the evaluations of the taste and texture of the product 14 are high, the second item evaluation unit 842 selects taste and texture as the Q evaluation items. The receiver extraction unit 846 extracts, from among one or more users, users who have a strong preference for taste and texture and / or users who have a weak preference for appearance as potential customers of the product 14.

[0196] In this embodiment, the notification generation unit 848 generates information regarding the product 14 (which may be referred to as notification information) to be notified to the users extracted by the receiver extraction unit 846. For example, the notification generation unit 848 determines an evaluation of the product 14 using the Q evaluation items determined by the second item evaluation unit 842. The notification generation unit 848 may determine an evaluation of the product 14 by the same procedure as the product evaluation unit 830. Further, the notification generation unit 848 generates notification information including information indicating the evaluation of the product 14. The notification generation unit 848 may generate the notification information by the same procedure as the transaction screen generation unit 832. The notification information may include the URL of the EC site or the URL of the product description page of the product 14.

[0197] In the present embodiment, the data transmission unit 860 transmits the notification information generated by the notification generation unit 848. For example, the data transmission unit 860 transmits the above notification information to the communication terminal used by the user extracted by the recipient extraction unit 846.

[0198] The transaction support unit 820 may be an example of a management device. The evaluation information extraction unit 822 may be an example of an evaluation information acquisition unit. The user information extraction unit 824 may be an example of a viewer information acquisition unit. The product evaluation unit 830 may be an example of an article evaluation unit. The notification generation unit 848 may be an example of a generation unit. The data transmission unit 860 may be an example of a transmission unit. A user who accesses the EC site may be an example of a viewer who views evaluations of articles. The overall evaluation value of product 12 may be an example of an evaluation value of an article.

[0199] FIG. 9 schematically shows an example of the internal configuration of the evaluation acquisition unit 462. In the present embodiment, the evaluation acquisition unit 462 includes a distribution status determination unit 912 and a distribution period determination unit 914. In the present embodiment, the evaluation acquisition unit 462 includes an evaluation support unit 920. In the present embodiment, the evaluation support unit 920 has an input item determination unit 922, an input screen generation unit 924, and an input screen transmission unit 926. In the present embodiment, the evaluation acquisition unit 462 includes a supply-side evaluation acquisition unit 932, a demand-side evaluation acquisition unit 934, and an evaluation data control unit 936. In the present embodiment, the evaluation acquisition unit 462 includes a deviation determination unit 942 and a deviation notification unit 944.

[0200] In this embodiment, the distribution status determination unit 912 acquires the distribution status information of each of one or more products 12 that have been traded in the past. For example, the distribution status determination unit 912 accesses the distribution management unit 114 to acquire one or more pieces of distribution status information. The distribution status determination unit 912 determines the distribution status of the product 12 based on the status of the product 12 in the distribution process indicated by the distribution status information of each of one or more products 12 that have been traded in the past. For example, the distribution status determination unit 912 expresses the status of the product 12 in the distribution process by continuous numerical values or stepwise classifications. For example, the distribution status determination unit 912 calculates a statistical value of the status of the product 12 indicated by one or more pieces of distribution status information, and expresses the status of the product 12 in the distribution process by continuous numerical values or stepwise classifications based on the statistical value.

[0201] In this embodiment, the distribution period determination unit 914 acquires the distribution period information of each of one or more products 12 that have been traded in the past. For example, the distribution status determination unit 912 accesses the distribution management unit 114 to acquire one or more pieces of distribution period information. The distribution period determination unit 914 may acquire production information and inspection information as the distribution period information. The distribution period determination unit 914 determines the length of the distribution period of the product 12 based on the length of the distribution period indicated by the distribution period information of each of one or more products 12 that have been traded in the past. For example, the distribution period determination unit 914 expresses the length of the distribution period of the product 12 by continuous numerical values or stepwise classifications. For example, the distribution period determination unit 914 calculates a statistical value of the length of the distribution period of the product 12 indicated by one or more pieces of distribution period information, and expresses the length of the distribution period of the product 12 by continuous numerical values or stepwise classifications based on the statistical value.

[0202] In this embodiment, the evaluation support unit 920 supports the input of the evaluation result of the product 12 by the consumer 44. For example, the evaluation support unit 920 generates the screen data of the evaluation input screen described in relation to FIGS. 6 and 7. The evaluation support unit 920 transmits the screen data of the evaluation input screen to the communication terminal 42 of the consumer 44. The screen data of the evaluation input screen may be data for causing the communication terminal 42 of the consumer 44 to display an evaluation input screen for inputting an evaluation of the product 12.

[0203] In this embodiment, the input item determination unit 922 determines evaluation items for which input of evaluation by the consumer 44 is requested on the evaluation input screen. For example, the input item determination unit 922 determines the types of one or more evaluation items for the consumer 44 to evaluate the product 12 based on at least one of the state of the product 12 indicated by the distribution state information and the length of the distribution period of the product 12 indicated by the distribution period information.

[0204] In one embodiment, when the state of the product 12 is worse than a predetermined standard, the input item determination unit 922 determines the types of one or more evaluation items so that the number of evaluation items for the consumer 44 to evaluate the product 12 is smaller compared to the case where the state of the product 12 is better than the predetermined standard. In other embodiments, when the length of the distribution period of the product 12 is greater than a predetermined value, the input item determination unit 922 determines the types of one or more evaluation items so that the number of evaluation items for the consumer 44 to evaluate the product 12 is smaller compared to the case where the length of the distribution period of the product 12 is smaller than the predetermined value. Thereby, the burden of input by the consumer 44 is reduced.

[0205] The input item determination unit 922 may determine the types of one or more evaluation items for the consumer 44 to evaluate the product 12 based on at least one of the state of the product 12 indicated by the distribution state information and the length of the distribution period of the product 12 indicated by the distribution period information, and at least one of the origin and item of the product 12. For example, when the origin of the product 12 matches or is included in a predetermined region, the input item determination unit 922 determines the types of one or more evaluation items by the same procedure as the above-described procedure. For example, when the item of the product 12 matches or is included in a predetermined item, the input item determination unit 922 determines the types of one or more evaluation items by the same procedure as the above-described procedure.

[0206] In this embodiment, the input screen generation unit 924 generates the screen data of the evaluation input screen. In this embodiment, the input screen transmission unit 926 transmits the screen data of the evaluation input screen to the communication terminal 42 of the consumer 44. As described above, the evaluation input screen is a screen for the consumer 44 to input the evaluation result for the product 12, and is a screen for assisting the input of the evaluation result for each of the one or more items determined by the input item determination unit 922.

[0207] In this embodiment, the supply-side evaluation acquisition unit 932 acquires supply-side evaluation information. As described in connection with FIG. 3, the supply-side evaluation acquisition unit 932 acquires supply-side evaluation information from, for example, the communication terminal 22 or the product 12. As described above, the supply-side evaluation information includes, for example, information indicating the evaluation result of the product 12 by the producer 20.

[0208] In this embodiment, the demand-side evaluation acquisition unit 934 acquires demand-side evaluation information. As described in connection with FIG. 3, the demand-side evaluation acquisition unit 934 acquires demand-side evaluation information from, for example, the communication terminal 42. As described above, the demand-side evaluation information includes, for example, information indicating the evaluation result of the product 12 by the consumer 44.

[0209] In this embodiment, the evaluation data control unit 936 controls the output destinations of the data of the supply-side evaluation information and the demand-side evaluation information. For example, the evaluation data control unit 936 acquires the supply-side evaluation information from the supply-side evaluation acquisition unit 932 and stores the supply-side evaluation information in the evaluation information storage unit 466. For example, the evaluation data control unit 936 acquires the demand-side evaluation information from the demand-side evaluation acquisition unit 934 and outputs the demand-side evaluation information to the evaluation correction unit 464 or the evaluation information storage unit 466.

[0210] For example, when at least one of the state of product 12 indicated by the distribution state information and the length of the distribution period of product 12 indicated by the distribution period information meets a predetermined condition, the evaluation data control unit 936 determines to store the demand-side evaluation information in the evaluation information storage unit 466. In this case, the evaluation data control unit 936 outputs the demand-side evaluation information to the evaluation information storage unit 466. Examples of the above-mentioned predetermined conditions include the condition that the state of product 12 in the distribution process is worse than a predetermined state, and the condition that the length of the distribution period is greater than a predetermined value.

[0211] On the other hand, when at least one of the state of product 12 indicated by the distribution state information and the length of the distribution period of product 12 indicated by the distribution period information does not meet the above-mentioned predetermined condition, there is a possibility that at least a part of the evaluation result indicated by the demand-side evaluation information is not appropriate. Therefore, the evaluation data control unit 936 decides: (i) not to store at least a part of the evaluation result indicated by the demand-side evaluation information in the evaluation information storage unit 466; (ii) correct at least a part of the evaluation result indicated by the demand-side evaluation information; or (iii) associate the demand-side evaluation information with information indicating that at least a part of the evaluation result indicated by the demand-side evaluation information may not be appropriate, and store it in the evaluation information storage unit 466.

[0212] When it is determined not to store at least a part of the evaluation result indicated by the demand-side evaluation information in the evaluation information storage unit 466, the evaluation data control unit 936 deletes a part of the demand-side evaluation information and then outputs the demand-side evaluation information to the evaluation information storage unit 466. As a result, the demand-side evaluation information with a part of the evaluation result deleted is stored in the evaluation information storage unit 466. The evaluation data control unit 936 may not output the demand-side evaluation information to the evaluation information storage unit 466.
