[0004] In order to accumulate information possessed by employees, employees may be made to input information into a storage device. However, there is a problem that the information input by employees is difficult to utilize because the information is fragmented or poorly expressed.

[0005] The present invention has been made in consideration of these points, and has an object to store information in a format that is easy to use. [Means for solving the problem]

[0006] A first aspect of the present invention is an information processing device. The information processing device includes a storage unit that stores product information, which is information about a product, or service information, which is information about a service, a first reception unit that receives an input of additional information for the product information of a predetermined product or the service information of a predetermined service from a terminal used by a user, an estimation unit that estimates an input intention, which is the intention of the user when inputting the additional information, based on the product information of the predetermined product or the service information of the predetermined service and the additional information, a second reception unit that receives from the terminal whether the estimated input intention is correct, and a storage control unit that, when the second reception unit receives that the estimated input intention is correct, stores the input intention in the storage unit in association with the product information of the predetermined product or the service information of the predetermined service.

[0007] The estimation unit may input instruction information for the large-scale language model to the large-scale language model, the instruction information including a template for causing the large-scale language model to estimate the input intention, the additional information, and the product information or the service information, and may estimate the input intention corresponding to the additional information by acquiring an input intention included in an answer output from the large-scale language model.

[0008] The estimation unit may input the product information of the specified product or the service information of the specified service and the additional information accepted by the first reception unit into a learning model that has learned the product information or the service information, the additional information, and the input intention as teacher data and outputs an input intention in response to input of the product information or the service information and the additional information, and may estimate the input intention corresponding to the additional information by obtaining the input intention output from the learning model.

[0009] The estimation unit may estimate multiple input intentions, and the second reception unit may receive from the terminal whether each of the multiple estimated input intentions is correct, and the memory control unit may store in the memory unit an input intention that the second reception unit has received as correct from the multiple estimated input intentions, in association with the product information of the specified product or the service information of the specified service.

[0010] The product information or service information may be associated with category information indicating the category to which the product or service belongs, and the second reception unit may receive from the terminal whether the input intention received as correct can be applied to other products or other services that belong to the same category as the category to which the specified product or the specified service belongs, and when the second reception unit receives that the input intention received as correct can be applied to other products or other services, the memory control unit may store the input intention in the memory unit in association with product information of the other products or service information of the other services.

[0011] The memory unit may store the product information or the service information in association with user identification information for identifying a user who handles the product corresponding to the product information or the service corresponding to the service information, and the memory control unit may associate the input intention accepted as correct with the product information or the service information in the memory unit, on the condition that the user identification information of the user who inputted the additional information is associated with the product information of the specified product or the service information of the specified service.

[0012] The system may further include an evaluation unit that evaluates the user who inputs the additional information, and the memory control unit may associate user identification information for identifying the user with the evaluation result of the user by the evaluation unit and store them in the memory unit.

[0013] The evaluation unit may evaluate the user based on at least one of the number of times the user inputs the additional information and the number of times an input intention corresponding to the additional information is stored by the storage control unit.

[0014] A second aspect of the present invention is an information processing method, which includes the steps of: receiving, from a terminal used by a user, an input of additional information for product information, which is information about a predetermined product, or service information, which is information about a predetermined service, executed by a computer; estimating an input intention, which is the intention of the user when inputting the additional information, based on the product information of the predetermined product or the service information of the predetermined service stored in a storage unit and the received additional information; receiving from the terminal whether the estimated input intention is correct; and, when it is received that the estimated input intention is correct, storing the input intention in the storage unit in association with the product information of the predetermined product or the service information of the predetermined service. Effect of the Invention

[0015] The present invention has the effect of allowing information to be stored in a format that is easy to use. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] [Overview of information processing device 1] 1 is a diagram showing an overview of an information processing device 1. The information processing device 1 is a computer for accumulating knowledge about customer service by employees and the like. The information processing device 1 is communicably connected to a user terminal 2 used by store employees and the like as users of the information processing device 1 to accumulate knowledge about customer service by employees and the like. The user terminal 2 is a computer such as a personal computer, a smartphone, or a tablet, for example.

[0018] First, the information processing device 1 accepts, from the user terminal 2, a designation of a specific product for which the user wishes to input additional information, and causes the user terminal 2 to display product information of the designated specific product ((1) in FIG. 1). The information processing device 1 accepts, from the user terminal 2, input of additional information for the product information of the specific product ((2) in FIG. 1).

[0019] The information processing device 1 estimates an input intention, which is the user's intention for inputting the additional information, based on the accepted input additional information and pre-stored product information of a specific product ((3) in FIG. 1). Then, the information processing device 1 displays the estimated input intention on the user terminal 2 ((4) in FIG. 1), and receives from the user terminal 2 whether the input intention is correct ((5) in FIG. 1). If the input intention is correct, that is, when the information processing device 1 receives from the user terminal 2 that the input intention is correct, it stores the input intention in association with the product information of the specific product ((6) in FIG. 1).

[0020] In this way, the information processing device 1 can infer the intention of inputting the additional information based on the additional information and the product information, and can supplement the missing information even if the additional information input by the employee is fragmentary or poorly expressed, thereby storing information in an easy-to-use format.

[0021] [Functional configuration of information processing device 1] Next, a description will be given of functions of the information processing device 1. Fig. 2 is a diagram showing a functional configuration of the information processing device 1. The information processing device 1 has a communication unit 11, a storage unit 12, and a control unit 13.

[0022] The communication unit 11 is a communication interface for transmitting and receiving data to and from an external device such as the user terminal 2 via a communication network such as the Internet or a mobile phone line. The storage unit 12 is a storage medium that stores various data, and includes a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk, etc. The storage unit 12 stores a program executed by the control unit 13. The storage unit 12 stores a program that causes the control unit 13 to function as a first reception unit 131, an estimation unit 132, a second reception unit 133, a memory control unit 134, and an evaluation unit 135.

[0023] The storage unit 12 also stores product identification information for identifying a product in association with product information, which is information related to the product. The product identification information is, for example, a product name and a product code. The product information is the price, size, description, and image of the product.

[0024] The control unit 13 is, for example, a CPU (Central Processing Unit). The control unit 13 executes a program stored in the storage unit 12 to function as a first reception unit 131, an estimation unit 132, a second reception unit 133, a storage control unit 134, and an evaluation unit 135.

[0025] The first reception unit 131 receives input of additional information for product information of a predetermined product from the user terminal 2 used by the user. For example, first, the first reception unit 131 receives product identification information of the predetermined product from the user terminal 2, thereby receiving designation of the predetermined product. Then, the first reception unit 131 displays product information of the specified predetermined product on the user terminal 2, and causes a reception screen for receiving input of additional information for the product information of the predetermined product to be displayed on the user terminal 2, and receives input of the additional information for the product information of the predetermined product from the user terminal 2.

[0026] Fig. 3 is a diagram showing an example of a reception screen. In the example shown in Fig. 3, it can be seen that a Chinese steamer has been specified as the predetermined product by the user, and the sentence "It can hold two meat buns or six shumai" has been input as additional information. When an OK button provided on the reception screen is pressed with the additional information input on the reception screen, the first reception unit 131 receives the additional information.

[0027] The estimation unit 132 estimates an input intention, which is the intention of the user when inputting the additional information, based on the product information of a predetermined product and the additional information accepted by the first accepting unit 131. Specifically, the estimation unit 132 inputs a prompt, which is instruction information for the large-scale language model, including a template for causing the large-scale language model to estimate the input intention, the additional information, and the product information, to the large-scale language model. Then, the estimation unit 132 estimates one or more input intentions corresponding to the additional information by acquiring the input intention included in the answer output from the large-scale language model.

[0028] FIG. 4 is a diagram showing an example of a prompt to be input to a large-scale language model. In the example shown in FIG. 4, it can be seen that a standard command sentence is included, "An experienced employee has added the following information to the following product information to be posted on the EC site. Please guess why the experienced employee added that information." In addition, in the example shown in FIG. 4, it can be seen that the additional information input in FIG. 3 and the product information displayed on the reception screen in FIG. 3 are included in the prompt.

[0029] Note that the estimation unit 132 estimates the input intention corresponding to the additional information by inputting a prompt to the large-scale language model and acquiring the input intention included in the answer output from the large-scale language model, but this is not limited to the above.

[0030] The estimation unit 132 may estimate an input intention corresponding to the additional information using a learning model that outputs an input intention in response to input of product information and additional information, the learning model having previously learned product information, additional information added in the past, and the input intention of the additional information as teacher data. In this case, the estimation unit 132 may input product information of a predetermined product and the additional information accepted by the first accepting unit 131 to the learning model, and obtain the input intention output from the learning model, thereby estimating an input intention corresponding to the additional information. In this way, the information processing device 1 can estimate an input intention in the same way as in the case of using a large-scale language model.

[0031] The second receiving unit 133 receives from the user terminal 2 whether the input intention estimated by the estimation unit 132 is correct. The second receiving unit 133 receives from the user terminal 2, for each of the one or more input intentions estimated by the estimation unit 132, whether the input intention is correct.

[0032] For example, the second reception unit 133 displays on the user terminal 2 a first selection screen that accepts a selection of whether each of the one or more input intentions estimated by the estimation unit 132 is correct, and receives from the user terminal 2, via the first selection screen, a selection of whether the input intention is correct for each of the one or more input intentions.

[0033] Fig. 5 is a diagram showing an example of the first selection screen. In the first selection screen shown in Fig. 5, it can be seen that a check box is provided for each of the four input intentions estimated by the estimation unit 132, and an OK button is also provided. When the OK button provided on the first selection screen is pressed, the second reception unit 133 receives from the user terminal 2 the input intention with a check mark entered in the check box as the correct input intention.

[0034] When the second receiving unit 133 receives that the estimated input intention is correct, the memory control unit 134 associates the input intention with product information of a predetermined product and stores the input intention in the memory unit 12. Specifically, the memory control unit 134 stores, in the memory unit 12, the input intention that the second receiving unit 133 has received as correct, out of the multiple estimated input intentions, and the additional information, in association with the product information of the predetermined product.

[0035] In the example shown in FIG. 5, the memory control unit 134 associates with the product information of a specific product additional information "It contains two meat buns or six shumai" and an input intention "By replacing the abstract concept of 'steamed food' with the concrete numbers 'two meat buns' and 'six shumai,' consumers can more easily imagine how easy the product is to use."

[0036] The information processing device 1 may apply the correct input intention to other products that belong to the same category as a given product. In this case, the storage unit 12 stores product information of the product in association with category information indicating one or more categories to which the product belongs and lower category information indicating categories lower than the category to which the product belongs.

[0037] The second receiving unit 133 refers to the memory unit 12, identifies a category to which the specific product received by the first receiving unit 131 belongs, and identifies one or more other products that belong to the same category. The second receiving unit 133 refers to the memory unit 12, and identifies a subcategory of each of the one or more other products. Then, the second receiving unit 133 receives from the user terminal 2 a request as to whether the input intention received as correct can be applied to the identified other products.

[0038] The second receiving unit 133 groups one or more other products into subcategories, and receives from the user terminal 2 whether the input intention received as correct can be applied to each subcategories. For example, the second receiving unit 133 displays on the user terminal 2 a second selection screen that receives a selection of other products to which the correct input intention received by the second receiving unit 133 can be applied, and receives from the user terminal 2, via the second selection screen, whether the correct input intention can be applied to the other products for each subcategories.

[0039] Fig. 6 is a diagram showing an example of the second selection screen. In the example shown in Fig. 6, "pot" is identified as the category to which the Chinese steamer belongs, and it can be seen that the second selection screen has check boxes for accepting whether or not the selected input intention is to be applied to each of the other products that belong to the same category as "pot" and are in a subcategory of "pot", and an OK button. When the OK button on the second selection screen is pressed, the second reception unit 133 accepts the other products corresponding to the subcategory for which a check mark has been entered in the check box as other products to which the correct input intention is to be applied.

[0040] Then, when the second receiving unit 133 receives that the input intention received as correct can be applied to other products, the memory control unit 134 associates the input intention with product information of other products in the subcategory in which a check mark has been entered, and stores the input intention in the memory unit 12. In the example shown in FIG. 6, the second receiving unit 133 accepts other products that belong to "saucepan," a subcategory of "saucepan," among other products associated with the category "saucepan" to which Chinese steamers belong, as other products to which the input intention received as correct can be applied. For this reason, the memory control unit 134 associates additional information with the input intention received as correct for product information of other products in the subcategory "saucepan."

[0041] In addition, among users, there are employees who have been handling the product for a long time and are knowledgeable about the product, and employees who have been handling the product for a short time and are not knowledgeable about the product. In addition, there is a high probability that the additional information of an employee who is knowledgeable about the product and the input intention corresponding to the additional information are valid. In response to this, the storage control unit 134 may store the input intention corresponding to the additional information entered by an employee who is likely to be knowledgeable about a specific product in association with the product information of the specific product.

[0042] In this case, the storage unit 12 stores product information corresponding to the product in association with a user ID as user identification information for identifying a user who handles the product. The first reception unit 131 receives the additional information from the user terminal 2 and acquires the user ID of the user who input the additional information. On the condition that the user ID of the user who inputs the additional information is associated with product information of a specific product and stored in the storage unit 12, the storage control unit 134 associates the input intention that the second reception unit 133 has accepted as correct with the product information and stores the product information in the storage unit 12.

[0043] Furthermore, the storage unit 12 may store the user ID of the user in association with the category of the product handled by the user. Then, the storage control unit 134 may store the input intention that the second receiving unit 133 has accepted as correct in association with the product information on a specific product, on condition that the category associated with the product information of the specific product is included in the category associated with the user ID of the user who input the additional information, in the storage unit 12. In this way, the information processing device 1 can add additional information and input intention that have been entered by an employee who is knowledgeable about the product and that are highly likely to be valuable for sharing with other employees, to the product information.

[0044] In addition, the memory unit 12 is configured to add additional information and input intentions of employees who are knowledgeable about the product to the product information, but this is not limited to the above, and the memory unit 12 may also be configured to add additional information and input intentions of employees who are not knowledgeable about the product to the product information.

[0045] In this case, for example, the storage unit 12 stores a user ID, a product or a category to which the product belongs, and a proficiency level indicating the probability that the user is knowledgeable about the product or category in association with each other. The proficiency level may be determined based on, for example, the period during which the user has handled the product, evaluations from other users regarding the input of additional information, and the rank of the user's position in the store. Here, evaluations of the additional information and the input intention are received from other users, and the proficiency level may be determined based on the number of good evaluations received, or the proficiency level may be determined based on the number of views of the additional information and the input intention.

[0046] Then, when the amount of information of the product information is equal to or less than a predetermined amount, the storage control unit 134 may store the additional information and the input intention in association with the product information, regardless of the proficiency level corresponding to the user ID. In this case, the storage control unit 134 stores the additional information and the input intention in association with the product information, and also stores the additional information in association with the user ID of the user who inputted the additional information or the proficiency level of the user. When the amount of information of the product information is equal to or more than a predetermined amount and the additional information and the input intention are already associated with the product information, the storage control unit 134 identifies the proficiency level of the user corresponding to the already associated additional information.

[0047] The storage control unit 134 stores the new additional information and input intention in association with the product information, instead of the already associated additional information and input intention, on condition that the proficiency of the user who newly inputs additional information is higher than the specified proficiency. Furthermore, when the proficiency of the user who newly inputs additional information is equal to or lower than the specified proficiency, the storage control unit 134 stores the new additional information and input intention in association with the product information. In this way, the additional information associated with the product information can be updated to additional information that is likely to be worth sharing with other employees.

[0048] Furthermore, when the proficiency level corresponding to the user is lower than a predetermined threshold, the storage control unit 134 may not store the additional information and the input intention in association with the product information of the other product. In this case, the second reception unit 133 may not receive the other product to which the correct input intention is applied without displaying the second selection screen on the user terminal 2. Furthermore, when the proficiency level corresponding to the user is lower than a predetermined threshold, the storage control unit 134 may associate the additional information and the input intention as reference information with the product information of the predetermined product.

[0049] The evaluation unit 135 evaluates the user who inputs the additional information. For example, the evaluation unit 135 evaluates the user based on at least one of the number of times the user inputs additional information and the number of times the memory control unit 134 stores the input intention corresponding to the additional information in the memory unit 12. Then, the memory control unit 134 associates the user ID of the user with the evaluation result of the user by the evaluation unit 135 and stores it as evaluation information in the memory unit 12. In this way, the input of additional information increases the user's evaluation, so the information processing device 1 can increase the user's motivation to input additional information to increase their own evaluation, and promote the accumulation of knowledge by the user.

[0050] [Processing flow in information processing device 1] Next, a description will be given of the flow of processing in the information processing device 1. FIG 7 is a flowchart showing the flow of processing in the information processing device 1.

[0051] First, the first reception unit 131 receives a designation of a predetermined product from the user terminal 2 (S1). The first reception unit 131 displays product information of the designated predetermined product, and causes the user terminal 2 to display a reception screen for receiving input of additional information for the product information of the predetermined product, and receives the input of additional information for the product information of the predetermined product from the user terminal 2 (S2).

[0052] Next, the estimation unit 132 estimates one or more input intentions, which are the intentions of the user when inputting the additional information, based on the product information of the predetermined product and the additional information accepted by the first acceptance unit 131 (S3). Next, the second acceptance unit 133 causes the user terminal 2 to display a first selection screen that accepts whether each of the one or more input intentions estimated by the estimation unit 132 is correct, and accepts selection of the correct input intention from the one or more input intentions (S4).

[0053] Next, the memory control unit 134 determines whether the input intention is correct based on the content accepted by the second accepting unit 133 (S5). If the memory control unit 134 determines that the input intention is correct (YES in S5), the process proceeds to S6, and stores the input intention accepted as correct by the second accepting unit 133 and the additional information in association with product information of a predetermined product in the memory unit 12. If the memory control unit 134 determines that the input intention is not correct (NO in S5), the process related to this flowchart ends.

[0054] [Variations] In the above embodiment, the information processing device 1 estimates the input intention of additional information for the product information of a predetermined product, and when it has accepted that the input intention is correct, associates the input intention with the product information of the predetermined product and stores the input intention; however, this is not limited to the above. The information processing device 1 may accept, from the user terminal 2, a designation of a predetermined service for which the user desires to input additional information, and cause the user terminal 2 to display service information, which is information related to the designated predetermined service. The information processing device 1 may accept, from the user, an input of additional information for the service information of the predetermined service. Then, the information processing device 1 may estimate the input intention of the input additional information, and when it has accepted that the input intention is correct, associates the input intention with the service information of the predetermined service and stores the input intention.

[0055] [Effects of information processing device 1] As described above, the information processing device 1 according to this embodiment accepts input of additional information for product information of a predetermined product or service information of a predetermined service from the user terminal 2, and estimates an input intention, which is the intention of the user when inputting the additional information, based on the product information of the predetermined product or the service information of the predetermined service and the additional information. Then, when the information processing device 1 accepts that the estimated input intention is correct, it associates the input intention with the product information of the predetermined product or the service information of the predetermined service and stores the input intention in the storage unit 12. In this way, the information processing device 1 can accumulate information in an easy-to-use format.

[0056] Furthermore, this invention will make it possible to contribute to Goal 9 of the United Nations' Sustainable Development Goals (SDGs), which is to "build resilient infrastructure, promote industry, innovation and infrastructure."
