[0044] <Posting Control Process> Here, the posting control process will be described with reference to FIG. 6. The posting control process is a process executed by the control unit 30 at every predetermined cycle.

[0045] As shown in FIG. 6, in step S10, the control unit 30 determines whether or not a post has been received from the user terminal device 18. If the control unit 30 determines that a post has not been received from the user terminal device 18, the post control process ends. If the control unit 30 determines that a post has been received from the user terminal device 18, the process proceeds to step S11.

[0046] In step S11, the control unit 30 executes a post text acquisition process. In this process, the control unit 30 acquires the post text posted by the user from the post content received from the user terminal device 18.

[0047] In step S12, the control unit 30 executes a post evaluation result acquisition process. In this process, the control unit 30 acquires a post evaluation value as the post evaluation result posted by the user from the post content received from the user terminal device 18.

[0048] In step S13, the control unit 30 executes a post content registration process. In this process, the control unit 30 generates a post management ID. The control unit 30 acquires the transaction target ID corresponding to the post content. The control unit 30 acquires the user ID included in the post content. The control unit 30 may acquire the user ID based on the result authenticated by communication with the user terminal device 18. The control unit 30 acquires the current date and time as the post date and time. The control unit 30 registers the acquired transaction target ID, user ID, post date and time, post text, and post evaluation value in the post management database 31A so as to correspond to the post management ID. When registering the post content in the post management database 31A, the control unit 30 updates the number of posts corresponding to the transaction target ID in the transaction target database 31B.

[0049] <First Summary Control Process> Next, the first summary control process will be described with reference to FIG. 7. The first summary control process is a process executed by the control unit 30 at predetermined intervals.

[0050] As shown in FIG. 7, in step S20, the control unit 30 determines whether the first requirement condition is satisfied. The first requirement condition is satisfied when the posted content for the transaction target is registered, but is not limited thereto. When the control unit 30 determines that the first requirement condition is not satisfied, the first summary control process ends. When the control unit 30 determines that the first requirement condition is satisfied, the process proceeds to step S21.

[0051] In step S21, the control unit 30 executes a posted text acquisition process. In this process, the control unit 30 acquires the posted text for the transaction target posted by the user. Specifically, the control unit 30 refers to the posting management database 31A and acquires the latest specified number of posted texts from the posted texts corresponding to the transaction target for which the registration content is registered. That is, the control unit 30 acquires the specified number of posted texts in ascending order of the posting date and time. The specified number is an arbitrary number required to generate the first summary text, and may be, for example, 50, or may be, for example, 80.

[0052] In step S22, the control unit 30 executes an average posting evaluation value acquisition process. In this process, the control unit 30 acquires the posting evaluation results for the transaction target posted by the user. Specifically, the control unit 30 acquires the specified number of posting evaluation results corresponding to the posted texts acquired in step S21. The control unit 30 calculates the average value of the posting evaluation values included in the specified number of posting evaluation results. In this way, the control unit 30 acquires the average posting evaluation value corresponding to the specified number of posting evaluation results. The control unit 30 registers the acquired average posting evaluation value in the transaction target database 31B as the average posting evaluation value corresponding to the transaction target.

[0053] In step S23, the control unit 30 executes a first summary request process. In this process, the control unit 30 requests the generation of the first summary text for the transaction target. Specifically, the control unit 30 transmits the specified number of posted texts acquired in step S21 and the average posting evaluation value acquired in step S22 to the LLM server 13. The control unit 30 transmits an instruction to generate the first summary text based on the specified number of posted texts and the average posting evaluation value to the LLM server 13.

[0054] The control unit 30 sends an instruction to the LLM server 13 to adjust the content of the first summary text so that it becomes the ratio of positive content to negative content based on the average submission evaluation value. For example, when the average submission evaluation value is 4 out of 5 full marks, the control unit 30 sends an instruction to the LLM server 13 to adjust the content of the first summary text so that the ratio of positive content is more than that of negative content.

[0055] In step S24, the control unit 30 executes the first summary text acquisition process. In this process, the control unit 30 acquires the first summary text for the transaction target by receiving it from the LLM server 13. In particular, the control unit 30 acquires the first summary text according to the average submission evaluation value. Specifically, the control unit 30 acquires the first summary text whose ratio of positive content to negative content is based on the average submission evaluation value.

[0056] In step S25, the control unit 30 determines whether the re-acquisition condition is satisfied. The re-acquisition condition may be satisfied when the first summary text acquired in step S24 is not in the specified language. The specified language may be, for example, the language used on the website. The specified language may be, for example, the language designated by the administrator of the information processing device 11.

[0057] The re-acquisition condition may be satisfied when the first summary text acquired in step S24 contains predetermined prohibited terms. The prohibited terms may contain overly negative content. The re-acquisition condition may be satisfied when the amount of description of the first summary text acquired in step S24 is outside the predetermined allowable range. The allowable range may be, for example, 100 characters or more and 200 characters or less.

[0058] When the control unit 30 determines that the re-acquisition condition is satisfied, the process proceeds to step S21 again. When the control unit 30 determines that the re-acquisition condition is not satisfied, the process proceeds to step S26. As a result, the control unit 30 repeatedly executes steps S21 to S25 until the re-acquisition condition is satisfied. That is, when the re-acquisition condition is satisfied based on the first abstract, the control unit 30 re-acquires the first abstract for the transaction target.

[0059] In step S26, the control unit 30 executes the first abstract registration process. In this process, the control unit 30 registers the first abstract acquired in step S24 in the transaction target database 31B so as to correspond to the transaction target ID.

[0060] <Posting item control process> Next, the posting item control process will be described with reference to FIG. 8. The posting item control process is a process executed by the control unit 30 at a predetermined cycle.

[0061] As shown in FIG. 8, in step S30, the control unit 30 determines whether the second requirement condition is satisfied. The second requirement condition may be satisfied after the end of the first abstract control process. When the control unit 30 determines that the second requirement condition is not satisfied, the posting item control process ends. When the control unit 30 determines that the second requirement condition is satisfied, the process proceeds to step S31.

[0062] In step S31, the control unit 30 executes the posting text acquisition process. In this process, the control unit 30 acquires a specified number of posting texts for the transaction target posted by the user in the same manner as in step S21.

[0063] In step S32, the control unit 30 executes the transaction target type acquisition process. In this process, the control unit 30 refers to the transaction target database 31B and acquires the type of the transaction target corresponding to the transaction target ID.

[0064] In step S33, the control unit 30 executes a posting item request process. In this process, the control unit 30 requests the generation of posting items regarding the posting text for the transaction target. Specifically, the control unit 30 transmits the specified number of posting texts acquired in step S31 and the type of the transaction target acquired in step S32 to the LLM server 13. The control unit 30 transmits an instruction to the LLM server 13 to generate posting items regarding the posting text based on the specified number of posting texts and the type of the transaction target.

[0065] The control unit 30 transmits an instruction to the LLM server 13 to generate posting items based on the type of the transaction target. For example, when the type of the transaction target is sneakers, the control unit 30 transmits an instruction to the LLM server 13 to generate appropriate posting items based on the sneakers.

[0066] The control unit 30 transmits an instruction to the LLM server 13 to generate a predetermined number of posting items. The predetermined number may be a plurality, for example, 6 or more and 9 or less. The control unit 30 transmits an instruction to the LLM server 13 to generate a predetermined number of posting items in descending order of the number of postings of the posting texts corresponding to the posting items.

[0067] In step S34, the control unit 30 executes a posting item acquisition process. In this process, the control unit 30 acquires a plurality of posting items by receiving a plurality of posting items regarding the posting text from the LLM server 13. In particular, the control unit 30 acquires a plurality of posting items based on the type of the transaction target. The control unit 30 acquires a predetermined number of posting items. The control unit 30 acquires a predetermined number of posting items in descending order of the number of postings.

[0068] In step S35, the control unit 30 executes a posting item registration process. In this process, the control unit 30 generates a posting item management ID corresponding to each of the plurality of posting items acquired in step S34. For each of the plurality of posting items acquired in step S34, the control unit 30 registers the posting item and the posting item management ID in the transaction target database 31B so as to correspond to the transaction target ID.

[0069] <Item Evaluation Control Process> Next, the item evaluation control process will be described with reference to FIG. 9. The item evaluation control process is a process executed by the control unit 30 at predetermined intervals.

[0070] As shown in FIG. 9, in step S40, the control unit 30 determines whether the third requirement condition is satisfied. The third requirement condition may be satisfied after the completion of the posted item control process. If the control unit 30 determines that the third requirement condition is not satisfied, the item evaluation control process ends. If the control unit 30 determines that the third requirement condition is satisfied, the process proceeds to step S41.

[0071] In step S41, the control unit 30 executes the posted item acquisition process. In this process, the control unit 30 refers to the transaction target database 31B and acquires all the posted items corresponding to the transaction target.

[0072] In step S42, the control unit 30 executes the posted text acquisition process. In this process, the control unit 30 acquires a prescribed number of posted texts for the transaction target posted by the user in the same manner as in step S21. The control unit 30 acquires the posted management IDs corresponding to each of the prescribed number of posted texts.

[0073] In step S43, the control unit 30 executes the item evaluation request process. In this process, the control unit 30 requests the generation of an evaluation of the posted text for each posted item. Specifically, the control unit 30 transmits all the posted items acquired in step S41, and the combination of the prescribed number of posted texts and posted management IDs acquired in step S42 to the LLM server 13.

[0074] The control unit 30 sends an instruction to the LLM server 13 to generate an evaluation classification corresponding to a specified number of posted texts for each posted item. The control unit 30 sends an instruction to the LLM server 13 to generate an evaluation classification from any of whether the posted text is positive content regarding the posted item, whether the posted text is negative content regarding the posted item, or whether the posted text is content unrelated to the posted item.

[0075] The control unit 30 sends an instruction to the LLM server 13 to answer the correspondence relationship among the posted item, the posting management ID, and the evaluation classification. Thereby, the control unit 30 can specify the posting management ID and the evaluation classification regarding the posted item for each posted item.

[0076] In step S44, the control unit 30 executes item evaluation result acquisition processing. In this processing, the control unit 30 acquires by receiving from the LLM server 13 a combination of the posted item, the posting management ID, and the evaluation classification.

[0077] The control unit 30 calculates an item evaluation value for each posted item based on the evaluation classification corresponding to the posted item. Specifically, the control unit 30 calculates the number of positive evaluations evaluated as positive content and the number of negative evaluations evaluated as negative content as the evaluation classification for each of the plurality of posted items. The control unit 30 calculates the ratio of the number of positive evaluations to the number of negative evaluations as the item evaluation value for each of the plurality of posted items.

[0078] In this way, the control unit 30 acquires the item evaluation results corresponding to each of the plurality of posted items by sending the posted text to the LLM server 13. The control unit 30 calculates the item evaluation values corresponding to each of the plurality of posted items based on the item evaluation results.

[0079] In step S45, the control unit 30 executes item evaluation result registration processing. In this processing, the control unit 30 registers the item evaluation value acquired in step S44 in the transaction target database 31B so as to correspond to the posting item management ID.

[0080] The control unit 30 registers the posting management ID and the evaluation classification acquired in step S44 in the transaction target database 31B so as to correspond to the posting item management ID. In particular, the control unit 30 registers the evaluation classification, which is either positive or negative content, and the posting management ID in the transaction target database 31B so as to correspond to the posting item management ID. The control unit 30 may not register in the transaction target database 31B the evaluation classification and the posting management ID, which are content not related to the posting item. In this way, a posting text that is either positive or negative content is associated with the posting item. Hereinafter, the posting text corresponding to the posting item may be referred to as an item posting text.

[0081] The control unit 30 calculates the number of posting management IDs of the item posting text for each posting item management ID. The control unit 30 registers the calculated number of posting management IDs in the transaction target database 31B as the item posting count corresponding to the posting item management ID. That is, the control unit 30 registers, in the transaction target database 31B, as the item posting count, the number of item posting texts that are either positive or negative content with respect to the posting item among the prescribed number of posting texts for the transaction target.

[0082] The control unit 30 reads out, from the transaction target database 31B, the posting management IDs of the item posting text corresponding to the posting item management ID for each posting item management ID. The control unit 30 reads out, from the posting management database 31A, the posting evaluation value corresponding to the posting management ID for each posting item management ID. The control unit 30 reads out, from the transaction target database 31B, the item posting count corresponding to the posting item management ID for each posting item management ID. The control unit 30 calculates the item average posting evaluation value based on the posting evaluation value and the item posting count corresponding to the posting management ID for each posting item management ID. The control unit 30 registers the item average posting evaluation value in the transaction target database 31B so as to correspond to the posting item management ID.

[0083] <Excerpt control process> Next, the excerpt control process will be described with reference to FIG. 10. The excerpt control process is a process executed by the control unit 30 at every predetermined cycle.

[0084] As shown in FIG. 10, in step S50, the control unit 30 determines whether the fourth requirement condition is satisfied. The fourth requirement condition may be satisfied after the completion of the item evaluation control process. When the control unit 30 determines that the fourth requirement condition is not satisfied, it ends the extraction control process. When the control unit 30 determines that the fourth requirement condition is satisfied, it transfers the process to step S51.

[0085] In step S51, the control unit 30 executes a posting item acquisition process. In this process, similar to step S41, the control unit 30 refers to the transaction target database 31B and acquires all posting items corresponding to the transaction target.

[0086] In step S52, the control unit 30 executes an extraction target posting text acquisition process. In this process, the control unit 30 acquires all posting management IDs corresponding to all the posting items acquired in step S41 from the transaction target database 31B. The control unit 30 acquires the item posting texts corresponding to all the posting management IDs from the posting management database 31A as the extraction target posting texts. The extraction target posting texts are the posting texts to be the target of the extracted text. The control unit 30 acquires the posting management IDs corresponding to the extraction target posting texts respectively.

[0087] In step S53, the control unit 30 executes an extraction request process. In this process, the control unit 30 requests the generation of an extracted text for each posting item and extraction target posting text. Specifically, the control unit 30 transmits all combinations of all the posting items acquired in step S51, the extraction target posting texts acquired in step S52, and the posting management IDs to the LLM server 13.

[0088] The control unit 30 sends an instruction to the LLM server 13 to generate an excerpt text by extracting some content related to the posting item for all the excerpt target posting texts for each posting item. For example, the control unit 30 sends an instruction to the LLM server 13 to generate an excerpt text by extracting some content related to the cushioning posting item from the excerpt target posting text. The control unit 30 sends an instruction to the LLM server 13 to answer with a combination of the posting item, the posting management ID of the excerpt target posting text, the excerpt text, and the number of excerpt characters.

[0089] In step S54, the control unit 30 executes an excerpt text acquisition process. In this process, the control unit 30 acquires an excerpt text by extracting some content corresponding to the posting item from the excerpt target posting text corresponding to the posting item. Specifically, the control unit 30 acquires it by receiving from the LLM server 13 a combination of the posting item, the posting management ID of the excerpt target posting text, the excerpt text, and the number of excerpt characters.

[0090] In step S55, the control unit 30 executes an excerpt text registration process. In this process, the control unit 30 registers the acquired excerpt text and the number of excerpt characters in the transaction target database 31B so as to correspond to the posting item management ID and the posting management ID of the excerpt target posting text.

[0091] <Second Summary Control Process> Next, the second summary control process will be described with reference to FIG. 11. The second summary control process is a process executed by the control unit 30 at each predetermined cycle.

[0092] As shown in FIG. 11, in step S60, the control unit 30 determines whether the fifth requirement condition is satisfied. The fifth requirement condition may be satisfied after the completion of the excerpt control process. If the control unit 30 determines that the fifth requirement condition is not satisfied, the second summary control process ends. If the control unit 30 determines that the fifth requirement condition is satisfied, the process proceeds to step S61.

[0093] In step S61, the control unit 30 executes a posting item acquisition process. In this process, the control unit 30 refers to the transaction target database 31B and acquires all the posting items corresponding to the transaction target in the same manner as in step S41.

[0094] In step S62, the control unit 30 executes an item posting text acquisition process. In this process, the control unit 30 acquires the item posting text corresponding to the posting item management ID. Specifically, the control unit 30 acquires all the item posting texts corresponding to each of all the posting items acquired in step S61.

[0095] In step S63, the control unit 30 executes an item average posting evaluation value acquisition process. In this process, the control unit 30 acquires the posting evaluation result for the posting item. Specifically, the control unit 30 refers to the transaction target database 31B and acquires the item average posting evaluation value corresponding to the posting item as the posting evaluation result for the posting item.

[0096] In step S64, the control unit 30 executes a second summary request process. In this process, the control unit 30 requests the generation of a second summary text for the posting item. Specifically, the control unit 30 transmits the posting item acquired in step S61, the item posting text acquired in step S62, and the item average posting evaluation value acquired in step S63 to the LLM server 13.

[0097] The control unit 30 transmits an instruction to the LLM server 13 to generate a second summary text for each posting item based on the item posting text and the item average posting evaluation value. The control unit 30 transmits an instruction to the LLM server 13 to adjust the content of the second summary text so that it is the ratio of positive content to negative content based on the item average posting evaluation value.

[0098] In step S65, the control unit 30 executes the second abstract text acquisition process. In this process, the control unit 30 acquires the second abstract text for the transaction target by receiving it from the LLM server 13. In particular, the control unit 30 acquires the second abstract text corresponding to the item average posting evaluation value of the posting item. Specifically, the control unit 30 acquires the second abstract text that is the ratio of the positive content to the negative content based on the item average posting evaluation value.

[0099] In step S66, the control unit 30 determines whether the re-acquisition condition is satisfied. The re-acquisition condition may be satisfied when the second abstract text acquired in step S65 is not in the specified language. The re-acquisition condition may be satisfied when the second abstract text acquired in step S65 contains a predetermined prohibited term. The re-acquisition condition may be satisfied when the description amount of the second abstract text acquired in step S65 is outside the predetermined allowable range.

[0100] When the control unit 30 determines that the re-acquisition condition is satisfied, the process returns to step S61 again. When the control unit 30 determines that the re-acquisition condition is not satisfied, the process proceeds to step S67. Thus, the control unit 30 repeatedly executes steps S61 to S66 until the re-acquisition condition is satisfied. That is, when the re-acquisition condition is satisfied based on the second abstract text, the control unit 30 acquires the second abstract text for the transaction target again.

[0101] In step S67, the control unit 30 executes the second abstract text registration process. In this process, the control unit 30 registers the second abstract text acquired in step S65 in the transaction target database 31B so as to correspond to the posting item management ID.

[0102] <Information provision control process> Next, the information provision control process will be described with reference to FIG. 12. The information provision control process is a process executed by the control unit 30 at a predetermined cycle.

[0103] As shown in FIG. 12, in step S70, the control unit 30 determines whether there is a request for transaction target information from the user terminal device 18. The request for transaction target information is transmitted from the user terminal device 18 to the information processing device 11 in response to a user's instruction. The request for transaction target information includes a transaction target ID. The transaction target information is information regarding the transaction target. The transaction target information includes a first summary sentence, a plurality of posting items, and item evaluation values. The transaction target information may include the name, price, average posting evaluation value, still image, and moving image of the transaction target.

[0104] When the control unit 30 determines that there is no request for transaction target information from the user terminal device 18, the process proceeds to step S74. When the control unit 30 determines that there is a request for transaction target information from the user terminal device 18, the process proceeds to step S71.

[0105] In step S71, the control unit 30 executes transaction target information acquisition processing. In this processing, the control unit 30 acquires transaction target information. Specifically, the control unit 30 acquires the first summary sentence, a plurality of posting items, and item evaluation values corresponding to the transaction target ID from the transaction target database 31B.

[0106] In step S72, the control unit 30 executes transaction target display determination processing. In this processing, the control unit 30 determines the display mode of the information indicating the posting items indicating the plurality of posting items. Specifically, the control unit 30 determines to display the information indicating the plurality of posting items in the display order with a high item evaluation value. The control unit 30 determines to attach high evaluation information to the information indicating the posting items whose item evaluation value is equal to or higher than the first threshold value. The control unit 30 determines to attach low evaluation information to the information indicating the posting items whose item evaluation value is lower than the first threshold value and equal to or lower than the second threshold value. The first threshold value is, for example, a value at which the ratio of the number of positive postings to the total number of positive and negative postings is 67%. The second threshold value is, for example, a value at which the ratio of the number of positive postings to the total number of postings is 33%.

[0107] In step S73, the control unit 30 executes a transaction target information providing process. In this process, the control unit 30 transmits transaction target information to the user terminal device 18 that requested the transaction target information.
