[0044] <Posting control processing> The posting control process will now be described with reference to Fig. 6. The posting control process is executed by the control unit 30 at predetermined intervals.

[0045] 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 control unit 30 ends the post control process. If the control unit 30 determines that a post has been received from the user terminal device 18, the control unit 30 proceeds to step S11.

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

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

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

[0049] <First summary control process> Next, the first summarization control process will be described with reference to Fig. 7. The first summarization 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 or not the first requirement condition is met. The first requirement condition is met when the posted content for the transaction target is registered, but is not limited to this. If the control unit 30 determines that the first requirement condition is not met, it ends the first summary control process. If the control unit 30 determines that the first requirement condition is met, it transitions to step S21.

[0051] In step S21, the control unit 30 executes a posted message acquisition process. In this process, the control unit 30 acquires posted messages for a transaction object posted by a user. In detail, the control unit 30 refers to the posting management database 31A, and acquires a prescribed number of the most recent posted messages from the posted messages corresponding to the transaction object whose registration contents are registered. That is, the control unit 30 acquires the prescribed number of posted messages in order of the most recent posting date and time. The prescribed number is any number required to generate a first summary message, 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 posting evaluation results for the trading object posted by the user. In detail, the control unit 30 acquires a prescribed number of posting evaluation results corresponding to the posted text acquired in step S21. The control unit 30 calculates the average posting evaluation value included in the prescribed number of posting evaluation results. In this manner, the control unit 30 acquires an average posting evaluation value corresponding to the prescribed number of posting evaluation results. The control unit 30 registers the acquired average posting evaluation value in the trading object database 31B as an average posting evaluation value corresponding to the trading object.

[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 a first summary for the transaction object. In detail, the control unit 30 transmits the prescribed number of posted messages 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 the LLM server 13 to generate a first summary based on the prescribed number of posted messages and the average posting evaluation value.

[0054] The control unit 30 transmits an instruction to the LLM server 13 to adjust the content of the first summary so that the ratio of positive content to negative content is based on the average posting rating value. For example, when the average posting rating value is 4 out of 5, the control unit 30 transmits an instruction to the LLM server 13 to adjust the content of the first summary so that the ratio of positive content is greater than the ratio of negative content.

[0055] In step S24, the control unit 30 executes a first summary acquisition process. In this process, the control unit 30 acquires a first summary for the transaction object by receiving it from the LLM server 13. In particular, the control unit 30 acquires a first summary according to the average posting evaluation value. More specifically, the control unit 30 acquires a first summary that is a ratio of positive content to negative content based on the average posting evaluation value.

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

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

[0058] If the control unit 30 determines that the re-acquisition condition is met, it transitions the process to step S21 again. If the control unit 30 determines that the re-acquisition condition is not met, it transitions the process to step S26. As a result, the control unit 30 repeatedly executes steps S21 to S25 until the re-acquisition condition is met. In other words, when the re-acquisition condition is met based on the first summary, the control unit 30 re-acquires the first summary for the transaction object.

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

[0060] <Post item control processing> Next, the posted item control process will be described with reference to Fig. 8. The posted item control process is a process executed by the control unit 30 at predetermined intervals.

[0061] As shown in Fig. 8, in step S30, the control unit 30 determines whether or not the second requirement condition is met. The second requirement condition may be met after the first summary control process is completed. If the control unit 30 determines that the second requirement condition is not met, it ends the posting item control process. If the control unit 30 determines that the second requirement condition is met, it transitions to step S31.

[0062] In step S31, the control unit 30 executes a process of acquiring posted messages. In this process, the control unit 30 acquires a prescribed number of posted messages for the transaction object posted by the user, in the same manner as in step S21.

[0063] In step S32, the control unit 30 executes a transaction object type acquisition process. In this process, the control unit 30 refers to the transaction object database 31B and acquires the type of the transaction object corresponding to the transaction object 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 related to posted messages for the transaction object. In detail, the control unit 30 transmits the prescribed number of posted messages acquired in step S31 and the type of transaction object 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 related to the posted messages based on the prescribed number of posted messages and the type of transaction object.

[0065] The control unit 30 transmits an instruction to generate a posting item based on the type of the trade object to the LLM server 13. For example, when the type of the trade object is sneakers, the control unit 30 transmits an instruction to the LLM server 13 to generate an appropriate posting item based on 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 of items, for example, 6 to 9. 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 posted messages 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 multiple posting items by receiving multiple posting items related to the posted text from the LLM server 13. In particular, the control unit 30 acquires multiple posting items based on the type of trading object. 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 posts.

[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 multiple posting items acquired in step S34. For each of the multiple posting items acquired in step S34, the control unit 30 registers the posting item and the posting item management ID in the transaction object database 31B so as to correspond to the transaction object ID.

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

[0070] As shown in FIG. 9, in step S40, the control unit 30 determines whether or not the third requirement condition is met. The third requirement condition may be met after the end of the posting item control process. If the control unit 30 determines that the third requirement condition is not met, it ends the item evaluation control process. If the control unit 30 determines that the third requirement condition is met, it transitions to step S41.

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

[0072] In step S42, the control unit 30 executes a posted message acquisition process. In this process, the control unit 30 acquires a prescribed number of posted messages for the trading object posted by the user, similar to step S21. The control unit 30 acquires posting management IDs corresponding to the prescribed number of posted messages, respectively.

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

[0074] The control unit 30 transmits an instruction to the LLM server 13 to generate an evaluation classification corresponding to a prescribed number of posted messages for each posting item. The control unit 30 transmits an instruction to the LLM server 13 to generate an evaluation classification based on whether the posted message has positive content related to the posting item, whether the posted message has negative content related to the posting item, or whether the posted message has content unrelated to the posting item.

[0075] The control unit 30 transmits an instruction to respond with the correspondence between the posting item, the posting management ID, and the evaluation category to the LLM server 13. This allows the control unit 30 to identify the posting management ID and the evaluation category related to the posting item for each posting item.

[0076] In step S44, the control unit 30 executes an item evaluation result acquisition process. In this process, the control unit 30 receives and acquires a combination of a posting item, a posting management ID, and an evaluation category from the LLM server 13.

[0077] The control unit 30 calculates an item evaluation value for each posting item based on the evaluation classification corresponding to the posting item. In detail, 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 evaluation classifications for each of the multiple posting 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 multiple posting items.

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

[0079] In step S45, the control unit 30 executes an item evaluation result registration process. In this process, 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 posted item management ID.

[0080] The control unit 30 registers the post management ID and the evaluation category acquired in step S44 in the transaction target database 31B so as to correspond to the post item management ID. In particular, the control unit 30 registers the evaluation category and the post management ID, which are positive or negative content, in the transaction target database 31B so as to correspond to the post item management ID. The control unit 30 does not need to register the evaluation category and the post management ID, which are unrelated to the post item, in the transaction target database 31B. In this way, the posted text, which is positive or negative content, is associated with the post item. Hereinafter, the posted text corresponding to the post item may be referred to as the item posted text.

[0081] The control unit 30 calculates the number of posting management IDs of the item posted messages for each posting item management ID. The control unit 30 registers the calculated number of posting management IDs in the trading target database 31B as the number of item posts corresponding to the posting item management ID. In other words, the control unit 30 registers the number of item posted messages that have positive or negative content for the posted item out of the specified number of posted messages for the trading target in the trading target database 31B as the number of item posts.

[0082] The control unit 30 reads out the posting management ID of the item posted message corresponding to the posting item management ID from the trading target database 31B for each posting item management ID. The control unit 30 reads out the posting evaluation value corresponding to the posting management ID from the posting management database 31A for each posting item management ID. The control unit 30 reads out the number of item posts corresponding to the posting item management ID for each posting item management ID from the trading target database 31B. The control unit 30 calculates the item average posting evaluation value based on the posting evaluation value and the number of item posts 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 trading target database 31B so as to correspond to the posting item management ID.

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

[0084] As shown in Fig. 10, in step S50, the control unit 30 determines whether or not the fourth requirement condition is met. The fourth requirement condition may be met after the item evaluation control process is completed. If the control unit 30 determines that the fourth requirement condition is not met, it ends the excerpt control process. If the control unit 30 determines that the fourth requirement condition is met, it transitions to step S51.

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

[0086] In step S52, the control unit 30 executes a process for obtaining posted text to be excerpted. In this process, the control unit 30 obtains all post management IDs corresponding to all post items obtained in step S41 from the transaction target database 31B. The control unit 30 obtains item posted texts corresponding to all post management IDs from the post management database 31A as posted texts to be excerpted. The posted texts to be excerpted are posted texts that will be the subject of excerpts. The control unit 30 obtains post management IDs corresponding to each posted text to be excerpted.

[0087] In step S53, the control unit 30 executes an excerpt request process. In this process, the control unit 30 requests the generation of an excerpt for each posting item and each post to be excerpted. In detail, the control unit 30 transmits to the LLM server 13 all of the posting items acquired in step S51 and all of the combinations of the posts to be excerpted and the posting management IDs acquired in step S52.

[0088] The control unit 30 transmits an instruction to the LLM server 13 to generate an excerpt by extracting a portion of the content related to the posting item for each posting item, for all posting messages to be excerpted. For example, the control unit 30 transmits an instruction to the LLM server 13 to generate an excerpt by extracting a portion of the content related to the posting item of cushioning from the posting messages to be excerpted. The control unit 30 transmits an instruction to the LLM server 13 to respond with a combination of the posting item, the posting management ID of the posting message to be excerpted, the excerpt, and the number of characters to be excerpted.

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

[0090] In step S55, the control unit 30 executes an excerpt registration process. In this process, the control unit 30 registers the acquired excerpt 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 posted text to be excerpted.

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

[0092] As shown in FIG. 11, in step S60, the control unit 30 determines whether or not the fifth requirement condition is met. The fifth requirement condition may be met after the excerpt control process is completed. If the control unit 30 determines that the fifth requirement condition is not met, it terminates the second summary control process. If the control unit 30 determines that the fifth requirement condition is met, it transitions to step S61.

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

[0094] In step S62, the control unit 30 executes an item-posted message acquisition process. In this process, the control unit 30 acquires an item-posted message corresponding to the posting item management ID. In more detail, the control unit 30 acquires all item-posted messages corresponding to 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 a posting evaluation result for the posting item. In detail, the control unit 30 refers to the transaction target database 31B, and acquires an item average posting evaluation value corresponding to the posting item as a 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 for the posting item. In detail, the control unit 30 transmits to the LLM server 13 the posting item acquired in step S61, the posting item sentence acquired in step S62, and the average posting evaluation value of the item acquired in step S63.

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

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

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

[0100] If the control unit 30 determines that the re-acquisition condition is met, it transitions the process to step S61 again. If the control unit 30 determines that the re-acquisition condition is not met, it transitions the process to step S67. As a result, the control unit 30 repeatedly executes steps S61 to S66 until the re-acquisition condition is met. In other words, when the re-acquisition condition is met based on the second summary, the control unit 30 re-acquires the second summary for the transaction object.

[0101] In step S67, the control unit 30 executes a second summary registration process. In this process, the control unit 30 registers the second summary 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 predetermined intervals.

[0103] As shown in FIG. 12, in step S70, the control unit 30 determines whether or not a request for trading object information has been received from the user terminal device 18. The request for trading object information is transmitted from the user terminal device 18 to the information processing device 11 in response to an instruction from the user. The request for trading object information includes a trading object ID. The trading object information is information related to the trading object. The trading object information includes a first summary sentence, a plurality of posted items, and an item evaluation value. The trading object information may include the name, price, average posted evaluation value, still image, and moving image of the trading object.

[0104] If the control unit 30 determines that there has been no request for transaction object information from the user terminal device 18, the control unit 30 proceeds to step S74. If the control unit 30 determines that there has been a request for transaction object information from the user terminal device 18, the control unit 30 proceeds to step S71.

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

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

[0107] In step S73, the control unit 30 executes a transaction object information providing process. In this process, the control unit 30 transmits the transaction object information to the user terminal device 18 that requested the transaction object information. In particular, the control unit 30 transmits the transaction object information to the user terminal device 18 so that the transaction object information is displayed in the display mode determined in step S72.

[0108] As a result, in the user terminal device 18, the terminal control unit 20 causes the terminal display unit 24 to display the transaction object information received from the information processing device 11. In detail, the terminal control unit 20 causes the terminal display unit 24 to display the first summary corresponding to the transaction object ID received from the information processing device 11 and information indicating a plurality of posting items.

[0109] In this manner, the control unit 30 causes the user terminal device 18 to display the first summary and the multiple posted items related to the transaction object. In particular, the control unit 30 causes the user terminal device 18 to display, based on the item evaluation values, the posted items with positive evaluations among the multiple posted items in a manner in which they are prioritized over the posted items with negative evaluations.

[0110] In step S74, the control unit 30 determines whether or not a request for posted item information has been received from the user terminal device 18. The request for posted item information is transmitted from the user terminal device 18 to the information processing device 11 in response to an instruction from the user. The request for posted item information includes a trading object ID and a posted item management ID. Hereinafter, the posted item specified by the user may be referred to as a specified posted item. The posted item information includes a second summary sentence, an item evaluation value, and an excerpt sentence. The posted item information may include multiple posted items.

[0111] The control unit 30 ends the information provision control process if it determines that there has been no request for posting item information from the user terminal device 18. If the control unit 30 determines that there has been a request for posting item information from the user terminal device 18, it proceeds to step S75.

[0112] In step S75, the control unit 30 executes a posting item information acquisition process. In this process, the control unit 30 acquires posting item information corresponding to the designated posting item. In detail, the control unit 30 acquires the second summary sentence, the item evaluation value, and the excerpt sentence corresponding to the posting item management ID of the designated posting item from the transaction target database 31B.

[0113] In particular, the control unit 30 acquires a predetermined number of excerpts with a large number of excerpt characters from a plurality of excerpts corresponding to the posting item management ID of the specified posting item. The predetermined number is one or more, but may be, for example, four.

[0114] In this way, the control unit 30 preferentially selects a posted message that contains a large amount of information related to the posting item from among a plurality of posted messages corresponding to the posting item. The control unit 30 acquires an excerpt that is an excerpt of a portion of the content corresponding to the posting item from among a plurality of posted messages corresponding to the posting item.

[0115] The control unit 30 may acquire a predetermined number of excerpts from a plurality of excerpts corresponding to the posting item management ID of the designated posting item so as to obtain a ratio between excerpts with positive content and excerpts with negative content based on the item evaluation value. In other words, the control unit 30 may select excerpts from a plurality of excerpts corresponding to the posting item so as to obtain a ratio between excerpts with positive content and excerpts with negative content based on the item evaluation value.

[0116] In step S76, the control unit 30 executes a posting item display determination process. In this process, the control unit 30 determines the display mode of information indicating a plurality of posting items, in the same manner as in step S72.

[0117] In step S77, the control unit 30 executes a posting item information providing process. In this process, the control unit 30 transmits the posting item information to the user terminal device 18 that requested the posting item information. In particular, the control unit 30 transmits the posting item information to the user terminal device 18 so that the posting item information is displayed in the display mode determined in step S76.

[0118] As a result, in the user terminal device 18, the terminal control unit 20 causes the terminal display unit 24 to display the posting item information received from the information processing device 11.

Therefore, the convenience of users regarding posted messages for transaction targets can be improved.

[0146] [Example of change] This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction.

[0147] In steps S21, S31, and S42, the control unit 30 may exclude posted messages with an amount of description less than a prescribed amount, and may acquire a prescribed number of posted messages from posted messages with an amount of description equal to or greater than the prescribed amount. The prescribed amount of description may be a level that can be estimated as an appropriate posted message. The prescribed amount of description may be, for example, 50 characters.

[0148] When registering the posted content in the post management database 31A, the control unit 30 may calculate an average posting evaluation value corresponding to the trading object ID, and update the average posting evaluation value corresponding to the trading object ID in the trading object database 31B.

[0149] In step S22, the control unit 30 may obtain an average posting evaluation value corresponding to all of the posted messages regarding the transaction target, instead of the average posting evaluation value corresponding to the specified number of posted messages obtained in step S21.

[0150] In step S22, the control unit 30 may correct the posting evaluation value posted by the user. For example, the control unit 30 may correct the posting evaluation value posted by the user based on the user's behavior history for the transaction object so as to increase the posting evaluation value. The behavior history may include impressions (IMP). The impressions indicate the number of times a web page corresponding to the transaction object was displayed. The behavior history may include click-through rates (CTR). The click-through rates indicate the ratio of the number of clicks to the number of times a web page corresponding to the transaction object was displayed. The behavior history may include conversions (CV). The conversions indicate the number of times a targeted behavior was performed starting from a web page corresponding to the transaction object. The conversions include the establishment of a transaction in an electronic commerce service, and include the purchase of a product or service in electronic commerce. The conversions include the establishment of a transaction in a travel service, and include the purchase of a product or service related to travel. For example, the control unit 30 may correct the posting evaluation result posted by a user with a high impression corresponding to the transaction object so as to increase the posting evaluation result. The control unit 30 may correct the posting evaluation result so as to increase the posting evaluation result posted by a user with a high click rate corresponding to the transaction target, for example. The control unit 30 may correct the posting evaluation result so as to increase the posting evaluation result posted by a user with a high conversion corresponding to the transaction target, for example.

[0151] In step S23, the control unit 30 may transmit a prescribed number of posting evaluation values ​​corresponding to the prescribed number of posted messages to the LLM server 13, rather than transmitting the average posting evaluation value to the LLM server 13. In this case, the control unit 30 may transmit the posted messages and the posting evaluation values ​​to the LLM server 13 so that the correspondence between the acquired posted messages and the posting evaluation values ​​can be identified.

[0152] In steps S23 and S64, when requesting the generation of the first summary sentence and the second summary sentence, the control unit 30 may send an instruction to the LLM server 13 to generate the first summary sentence and the second summary sentence without using prohibited terms.

[0153] In steps S23 and S64, when requesting the generation of the first summary and the second summary, the control unit 30 may send an instruction to the LLM server 13 to generate the first summary and the second summary in the language to be used.

[0154] In steps S23 and S64, when requesting the generation of the first summary and the second summary, the control unit 30 may transmit to the LLM server 13 an instruction to keep the amount of description in the first summary and the second summary within a predetermined allowable range.

[0155] In step S33, the control unit 30 may perform control so as to acquire posted items when the type of the transaction object corresponding to the transaction object is a permitted type, and not acquire posted items when the type of the transaction object corresponding to the transaction object is a restricted type. The restricted type may include, for example, medicines.

[0156] In step S33, the control unit 30 may transmit an instruction to the LLM server 13 not to generate a posting item in which the number of posted messages related to the posting item is equal to or less than a lower limit. The lower limit is, for example, three. By setting a lower limit on the number of posted messages related to the posting item in this manner, the reliability of the posting item can be ensured. This can improve the convenience for users regarding messages posted to trading objects.

[0157] In step S42, the control unit 30 may refer to the transaction target database 31B and obtain post management IDs corresponding to all the post items obtained in step S41. The control unit 30 may refer to the post management database 31A and obtain posted messages corresponding to all the post management IDs.

[0158] In step S43, the control unit 30 may transmit a statement unrelated to the evaluation of the transaction object itself to the LLM server 13 as an instruction to respond that the posted message is unrelated to the posting item as the evaluation result of the transaction object. The statement unrelated to the evaluation of the transaction object itself may include, for example, a statement regarding the evaluation of the transaction process of the transaction object, such as delivery and packaging.

[0159] In the item evaluation control process, the control unit 30 may select one of all posting items and a specified number of combinations of posted messages and posting management IDs, and repeatedly send the selected posting item, posted message, and posting management ID to the LLM server 13.

[0160] In step S53, the control unit 30 may select one of all combinations of posts to be excerpted and post management IDs for each post category, and send the selected posts to be excerpted and post management IDs for each post category to the LLM server 13. In this case, the control unit 30 may select a predetermined number of the latest combinations from all combinations of posts to be excerpted and post management IDs. The control unit 30 may select a predetermined number of combinations with the most description from all combinations of posts to be excerpted and post management IDs.

[0161] In the excerpt control process, the control unit 30 may repeatedly select one of all posting items and all combinations of the posting text to be excerpted and the posting management ID, and send the selected posting item, the posting text to be excerpted, and the posting management ID to the LLM server 13.

[0162] In step S63, the control unit 30 may obtain an item evaluation value corresponding to the posting item management ID. In step S64, the control unit 30 may transmit the item evaluation value, instead of the item average posting evaluation value, to the LLM server 13. In step S64, the control unit 30 may transmit the item average posting evaluation value and the item evaluation value to the LLM server 13.

[0163] The control unit 30 may cause the user terminal device 18 to display information indicating multiple posted items in an arbitrary display order, as long as the user terminal device 18 displays posted items with positive evaluations in a manner that prioritizes posted items over posted items with negative evaluations. The control unit 30 may cause the user terminal device 18 to display information indicating multiple posted items in an arbitrary manner, as long as the posted items with positive evaluations and posted items with negative evaluations can be recognized by the user. The arbitrary manner may be at least either the display size or the display color. The arbitrary manner may be displaying regardless of a user instruction, or switching from hidden to displayed in response to a user instruction.

[0164] The first requirement may be satisfied at a predetermined time. The first requirement may be satisfied when the trading object has a predetermined number or more of posts posted by a user within a predetermined period. The predetermined period may be, for example, three years, and the predetermined number may be, for example, 100.

[0165] The control unit 30 may execute at least any of the first summary control process, the posted item control process, the item evaluation control process, the excerpt control process, and the second summary control process at different triggers. For example, the control unit 30 may execute the excerpt control process when a request for posted item information is received from the user terminal device 18, and execute the second summary control process after the item evaluation control process is completed.

[0166] The control unit 30 may execute at least any one of the first summary control process, the posted item control process, the item evaluation control process, the excerpt control process, and the second summary control process at the same time as the same process. This reduces the control load of the information processing device 11. For example, the control unit 30 may execute the first summary control process, the posted item control process, and the item evaluation control process as the same process.

[0167] The information processing device 11 may receive information from the user terminal device 18 via, for example, the EC server 12. That is, the information processing device 11 may indirectly receive information from the user terminal device 18 by receiving information from the EC server 12. The information processing device 11 may receive posted content from the user terminal device 18 via, for example, the EC server 12. The information processing device 11 may receive a request for transaction object information and a request for posted item information from the user terminal device 18 via, for example, the EC server 12.

[0168] The information processing device 11 may transmit information to the user terminal device 18 via, for example, the EC server 12. That is, the information processing device 11 may indirectly transmit information to the user terminal device 18 by transmitting information to the EC server 12. The information processing device 11 may transmit the first summary, the multiple posting items, the second summary, and the excerpt to the user terminal device 18 via, for example, the EC server 12.

[0169] The information processing system 10 may provide a service other than the electronic commerce service. The information processing system 10 may provide, for example, a travel service. In this case, the posted content of the transaction target may be a posted message and a posted evaluation result related to the service traded in the travel service. The information processing system 10 may provide a video distribution service. In this case, the posted content of the transaction target may be a posted message and a posted evaluation result related to the video traded in the video distribution service. The information processing system 10 may provide multiple services. The information processing system 10 may not provide an electronic commerce service. In other words, the information processing system 10 may be a system that provides a service that is the subject of the transaction. The information processing system 10 itself may be a system that does not provide a service that is the subject of the transaction.

[0170] The LLM server 13 may manage at least one of the summary model and the translation model as an integrated learning model. The LLM server 13 may be provided with another learning model in addition to the summary model and the translation model.

[0171] The information processing device 11 may have the configuration of another server. The information processing device 11 may have, for example, a part or all of the configuration related to the EC server 12. The information processing device 11 may have, for example, a part or all of the configuration related to the LLM server 13.

[0172] The information processing device 11 may be composed of multiple servers. The multiple servers may include, for example, a server that manages the posted contents, and a server that manages the first summary, the posted items, the second summary, and the excerpts. The multiple servers may be managed by different administrators or the same administrator.

[0173] The term "at least any" as used herein means one or more of the desired options. As an example, the term "at least any" as used herein means only one option or both options if the number of options is two.
