[0056] [System 1 operation] The operation of the system 1 will be described below with reference to the drawings. Fig. 6 is a flowchart showing the operation of the system 1. Fig. 7 is a diagram showing a performance information table. Fig. 8 is a diagram showing a first prompt. Fig. 9 is a diagram showing a second prompt.

[0057] When the control circuit 12 of the first terminal 10 reads the programs stored in the memory circuit 14, these programs cause the control circuit 12 of the first terminal 10 to execute the operations described below. The programs cause the control circuit 12 to execute the acquisition performance information extraction means 30.

[0058] When the control circuit 212 of the second server 210 reads the programs PG stored in the memory circuit 214, these programs PG cause the control circuit 212 of the second server 210 to execute the operations described below.

[0059] The system 1 aims to generate promotional copy for travel products, such as examples 1 and 2 shown below, in response to a request from a first user. Example 1: "A luxurious holiday at a quiet, luxurious resort at Hotel C! A comfortable flight with Company A." Example 2: "Enjoy a blissful Hawaiian experience at a quiet, luxurious resort away from Waikiki! Overlooking the vast mountain range."

[0060] First, the first user operates the operation unit 26 of the first terminal 10 to input target travel product information I1, which includes details of the target travel product. The travel product is a travel-related product, and in this embodiment, it is a package tour. The target travel product is the travel product for which the first user wishes to generate promotional text. Promotional text is a relatively short sentence or phrase that advertises the travel product to the destination, such as the title of a package tour, which is an example of a travel product, or a hotel catchphrase in advertising materials. The target travel product information I1 includes at least one of the target travel product's travel destination, country, season, airline, hotel, departure time, and arrival time as details of the target travel product. In this embodiment, the target travel product information I1 includes the travel destination, country, season, airline, and hotel. For example, the target travel product information I1 includes "Hawaii" as a travel destination, "America" ​​as a country, "summer" as a season, "Company A" as an airline, and "Hotel C" as a hotel. As a result, the control circuit 12 of the first terminal 10 acquires the target travel product information I1 (step S1).

[0061] Here, the memory circuit 114 has a performance information DB 114a. The performance information DB 114a stores the performance information table shown in FIG. 7. The performance information table includes multiple pieces of performance information I2. Therefore, the memory circuit 114 stores multiple pieces of performance information I2. The performance information I2 includes past travel product promotional statements, past travel product details, and past provision records (provision records) of travel products corresponding to the past travel product promotional statements. Provision, for example, refers to sales. Past travel product promotional statements are promotional statements for past travel products that have been provided in the past. Past travel product details are details of the content of past travel products. In this embodiment, the past travel product details include the location, country, airline, hotel, and season. The provision record of past travel products includes at least one of the number of reservations, sales, total number of customers, and number of information views for the past travel product. The total number of customers is the number of customers who have used the past travel product. In other words, the total number of customers is the total number of people who participated in package tours, which are past travel products. The number of information views is the number of views of the website on which the past travel products are posted. In this embodiment, the provision history includes the number of reservations for the past travel products and the number of sales for the past travel products.

[0062] Next, the control circuit 12 (one or more computer control circuits and the acquired performance information extraction means 30) of the first terminal 10 extracts one or more pieces of acquired performance information I3 from the plurality of performance information I2 shown in FIG. 7 based on the target travel product information I1 (step S2). More specifically, the control circuit 12 (one or more computer control circuits and the acquired performance information extraction means 30) of the first terminal 10 extracts one or more pieces of acquired performance information I3 from the plurality of performance information I2 shown in FIG. 7 based on at least one of the travel destination, country, season, airline, hotel, and departure time included in the target travel product information I1. In this embodiment, the control circuit 12 of the first terminal 10 extracts one or more pieces of acquired performance information I2 that include at least one of the travel destination, country, season, airline, hotel, and departure time included in the target travel product information I1 from the performance information table as one or more pieces of acquired performance information I3. For example, the control circuit 12 of the first terminal 10 extracts one or more pieces of performance information I2 that include any of "Hawaii," "America," "Summer," "Company A," or "Hotel C" as one or more pieces of acquired performance information I3. For example, the control circuit 12 of the first terminal 10 extracts, as the acquired performance information I3, performance information I2 that includes, in past promotional text for travel products, "A luxury resort where you can interact with dolphins! A quiet, prestigious hotel 15 minutes by car from Waikiki" as shown in Figure 7. Note that the control circuit 12 of the first terminal 10 may further extract, as the acquired performance information I3, one or more performance information I2 that includes, in past promotional text for travel products, a content other than "A luxury resort where you can interact with dolphins! A quiet, prestigious hotel 15 minutes by car from Waikiki" as shown in Figure 7. In this way, the one or more pieces of acquired performance information I3 are information extracted from the plurality of pieces of performance information I2 shown in Figure 7, and therefore, are at least a portion of the plurality of pieces of performance information I2 shown in Figure 7.

[0063] Next, the control circuit 12 of the first terminal 10 transmits the target travel product information I1 and one or more pieces of acquisition history information I3 to the second server 210 via the network interface 16 (step S3). In response, the network interface 216 of the second server 210 receives the target travel product information I1 and one or more pieces of acquisition history information I3 and outputs the target travel product information I1 and one or more pieces of acquisition history information I3 to the control circuit 212. As a result, the control circuit 212 of the second server 210 (one or more computer control circuits, target travel product information acquisition means 220, acquisition history information acquisition means 222) acquires the target travel product information I1 and one or more pieces of acquisition history information I3 (step S11).

[0064] Next, the control circuit 212 (one or more computer control circuits / input information generating means 224) of the second server 210 generates input information I4, which is an instruction to the first LLM 318 to generate one or more promotional texts T for the target travel product, based on the target travel product information I1 and one or more pieces of acquisition history information I3 (step S12). The input information I4 includes the target travel product information I1, a first prompt P1 including an instruction to the first LLM 318, and one or more pieces of acquisition history information I3 referenced by the first LLM 318.

[0065] The first prompt P1 will now be described with reference to Fig. 8. The memory circuit 214 of the second server 210 stores the first prompt P1. The first prompt P1 includes an instruction X0 and a first condition X1 to a fourth condition X4.

[0066] Instruction X0 is an instruction to cause the first LLM 318 to generate ten patterns of promotional text T (tour promotional text) and promotional text patterns TP for the target travel product. Instruction X0 also includes an instruction to cause the first LLM 318 to generate the promotional text T (tour promotional text) and promotional text patterns TP so as to satisfy the first condition X1 through the fourth condition X4.

[0067] The promotional text pattern TP indicates the structure of the promotional text T for the target travel product. The promotional text pattern TP includes a combination of text that indicates the attributes of the promotional text T for the target travel product. If the promotional text T for the target travel product is "An exquisite holiday at a tranquil, high-end resort at Hotel C! A comfortable flight with Company A," the promotional text pattern TP includes, for example, "information about the hotel's location," "hotel characteristics," "intended tour purpose," and "airline characteristics." In other words, the promotional text pattern TP indicates that the promotional text T for the target travel product was generated by combining "information about the hotel's location," "hotel characteristics," "intended tour purpose," and "airline characteristics."

[0068] The first condition X1 includes an instruction to have the first LLM 318 read the target travel product information I1 when generating the target travel product promotional copy T.

[0069] The second condition X2 includes a plurality of reference promotional wording patterns TP1. Similar to the promotional wording patterns TP, each of the reference promotional wording patterns TP1 includes a combination of wordings that indicate the attributes of the travel product. For example, the reference promotional wording pattern TP1 includes "destination characteristics," "attractiveness of accommodation," and "unique experience." The second condition X2 includes instructions for the first LLM 318 to generate a promotional wording pattern TP based on the reference promotional wording pattern TP1 referenced by the first LLM 318. The reference promotional wording pattern TP1 is used as a reference for the promotional wording pattern TP. The third condition X3, described below, includes instructions for the first LLM 318 to generate promotional wording T for the target travel product separately from the promotional wording pattern TP. In this way, each of the reference promotional wording patterns TP1 is referenced by the first LLM 318 when generating one or more promotional wording T for the target travel product.

[0070] The third condition X3 includes the following instructions: The first LLM 318 generates promotional text T for the target travel product and promotional text pattern TP based on the acquisition performance information I3 and the reference promotional text pattern TP1.

[0071] Thus, the third condition X3 includes instructions for causing the first LLM 318 to learn a method for generating promotional wording patterns TP based on one or more past travel product titles. In this case, the first LLM 318 emphasizes the characteristics of past travel product promotional wording that has an excellent track record. In other words, the first LLM 318 generates the promotional wording pattern TP by preferentially extracting the characteristics of past travel product promotional wording that has an excellent track record. An excellent track record means a large number of reservations, a large number of sales, etc.

[0072] The fourth condition X4 includes instructions for causing the first LLM 318 to generate promotional text T (tour promotional text) and promotional text pattern TP for the target travel product based on the important information I7. Thus, the fourth condition X4 includes the important information I7. The important information I7 is one or more items reflected in one or more promotional texts T for the target travel product. The important information I7 is information included in the promotional text T for the target travel product that attracts the customer's attention. The important information I7 includes a hotel overview, room features, tour contents (hotel plans), etc. If the target travel product information I1 and one or more pieces of acquisition history information I3 include a hotel overview, room features, tour contents (hotel plans), etc., the first LLM 318 includes the hotel overview, room features, tour contents (hotel plans), etc. in the promotional text T for the target travel product and the promotional text pattern TP.

[0073] Next, the control circuit 212 of the second server 210 transmits the input information I4 to the third server 310 via the network interface 216 (step S13). In response, the network interface 316 of the third server 310 receives the input information I4 and outputs the input information I4 to the control circuit 312. As a result, the control circuit 312 of the third server 310 acquires the input information I4.

[0074] The input information I4 includes target travel product information I1, a first prompt P1, and one or more pieces of acquisition information I3. The first LLM 318 reads the target travel product information I1 based on the first condition X1 of the first prompt P1. Furthermore, the first LLM 318 reads the one or more pieces of acquisition information I3 based on the third condition X3 of the first prompt P1. The first LLM 318 then generates a promotional wording pattern TP in accordance with the second condition X2 and the third condition X3. Furthermore, the first LLM 318 generates promotional wording T for the target travel product based on the target travel product information I1, the one or more pieces of acquisition information I3, and the promotional wording pattern TP in accordance with the third condition X3 and the fourth condition X4. For example, the first LLM 318 generates "hotel location information" + "hotel features" + "expected tour purpose" + "airline features" as a promotional text pattern TP, and generates "An exquisite holiday at the quiet luxury resort of Hotel C! A comfortable air trip with Company A" as promotional text T for the target travel product. By repeating the above process 10 times, the first LLM 318 generates travel product promotional text information I5 that includes 10 patterns of promotional text patterns TP and promotional text T for the target travel product.

[0075] The control circuit 312 of the third server 310 transmits the travel product promotional wording information I5 to the second server 210 via the network interface 316. In response, the network interface 216 of the second server 210 receives the travel product promotional wording information I5 and outputs the travel product promotional wording information I5 to the control circuit 212. As a result, the control circuit 212 of the second server 210 (the control circuit of one or more computers / travel product promotional wording information acquisition means 226) acquires the travel product promotional wording information I5, which includes the ten promotional wording patterns TP generated by the first LLM 318 and the target travel product promotional wording T (step S14).

[0076] Next, the control circuit 212 of the second server 210 deletes the target travel product promotional phrases T having 100 or more characters from the 10 patterns of target travel product promotional phrases T included in the travel product promotional phrase information I5 (step S15). In this way, the control circuit 312 of the second server 210 (the control circuit / selection means 232 of one or more computers) selects one or more target travel product promotional phrases T based on the character length of the one or more target travel product promotional phrases T.

[0077] Next, the control circuit 212 of the second server 210 (a control circuit of one or more computers) acquires a second prompt P2 (step S16). In this embodiment, the memory circuit 214 of the second server 210 stores the second prompt P2. The control circuit 212 of the second server 210 then reads the second prompt P2. The second prompt P2 includes instructions for causing the second LLM 320 to score each of the one or more target travel product promotional phrases T (multiple target travel product promotional phrases) included in the travel product promotional phrase information I5. As shown in FIG. 9 , the second prompt P2 includes scoring criteria. The scoring criteria include at least one scoring item from among concreteness, information content, attractiveness, appeal, conciseness, grammatical accuracy, and originality. In this embodiment, the scoring criteria include "concreteness and information content," "attractiveness and appeal," "conciseness and readability," "grammatical accuracy and spelling," and "originality."

[0078] Next, the control circuit 212 of the second server 210 transmits the second prompt P2 and the travel product promotional message information I5 to the third server 310 via the network interface 216 (step S17). In response, the network interface 316 of the third server 310 receives the second prompt P2 and the travel product promotional message information I5 and outputs the second prompt P2 and the travel product promotional message information I5 to the control circuit 312. As a result, the control circuit 312 of the third server 310 acquires the second prompt P2 and the travel product promotional message information I5. In this way, in step S17, the control circuit 212 of the second server 210 (the control circuit / second prompt input means 228 of one or more computers) transmits the second prompt P2 to the second server 210, thereby inputting the second prompt P2 to the second LLM 320.

[0079] The second LLM 320 scores one or more target travel product promotional statements T included in the travel product promotional statement information I5 based on the second prompt P2. The second LLM 320 then generates scoring information I6 including the scoring results for the one or more target travel product promotional statements T. The scoring information I6 may also include a reason for the scoring of the one or more target travel product promotional statements T. The control circuit 312 of the third server 310 transmits the scoring information I6 to the second server 210 via the network interface 316. In response, the network interface 216 of the second server 210 receives the scoring information I6 and outputs the scoring information I6 to the control circuit 212. As a result, the control circuit 212 of the second server 210 (the control circuit / scoring information acquisition means 230 of one or more computers) acquires the scoring information I6 from the second LLM 320 (step S18).

[0080] Finally, the control circuit 212 of the second server 210 causes the display 20 to display one or more target travel product promotional statements T included in the travel product promotional statement information I5 and the scoring results included in the scoring result information I6 (step S19). This allows the first user to view one or more target travel product promotional statements T and their scoring results. The first user determines the target travel product promotional statement T to be used for the target travel product based on the one or more target travel product promotional statements T and their scoring results. This allows the control circuit 212 of the second server 210 to upload the target travel product promotional statement T to the travel agency's web server. As a result, the second user can view the target travel product promotional statement T using the second terminal 50.

[0081] [effect] System 1 is suitable for generating promotional text for travel products. More specifically, the control circuit 212 of the second server 210 generates input information I4, which instructs the first LLM 318 to generate one or more promotional texts T for the target travel product based on the target travel product information I1 and one or more pieces of acquired performance information I3. As a result, the first LLM 318 generates one or more promotional texts T for the target travel product using the one or more pieces of acquired performance information I3 as a reference. The one or more pieces of acquired performance information I3 include past promotional texts for the travel product and past performance records of providing the travel product. Therefore, the first LLM 318 can analyze past promotional texts for travel products with excellent performance records to generate one or more promotional texts T for the target travel product that are likely to have excellent performance records. As described above, System 1 is suitable for generating promotional text for travel products.

[0082] In the system 1, the first prompt includes instructions for causing the first LLM 318 to generate one or more promotional text patterns TP. Each of the one or more promotional text patterns TP includes a combination of text that indicates attributes of one or more target travel product promotional text T. Therefore, the first LLM 318 can generate one or more target travel product promotional text T based on the one or more promotional text patterns TP. This allows the first LLM 318 to learn the process of generating one or more target travel product promotional text T through the generation of the promotional text patterns TP. As a result, the first LLM 318 can generate one or more high-quality target travel product promotional text T. Furthermore, by viewing the one or more promotional text patterns TP, the first user can understand the process of generating one or more target travel product promotional text T.

[0083] In the system 1, the first prompt P1 includes a plurality of reference promotional wording patterns TP1. Each of the plurality of reference promotional wording patterns TP1 is referenced by the first LLM 318 when generating one or more target travel product promotional wordings T, and includes a combination of wordings that indicate the attributes of the travel product. In this way, if the first prompt P1 includes a plurality of reference promotional wording patterns TP1 that are likely to have a good performance record, the first LLM 318 can generate one or more target travel product promotional wordings T that are likely to have a good performance record.

[0084] In the system 1, the first prompt P1 includes instructions for causing the first LLM 318 to generate one or more promotional wording patterns TP based on the reference promotional wording pattern TP1 referenced by the first LLM 318. As a result, if the first prompt P1 describes multiple reference promotional wording patterns TP1 that are likely to have a good performance record, the first LLM 318 can generate one or more promotional wording patterns TP that are likely to have a good performance record. Furthermore, the first LLM 318 can generate one or more promotional wordings T for the target travel product that are likely to have a good performance record based on the one or more promotional wording patterns TP that are likely to have a good performance record.

[0085] In the system 1, the first prompt P1 includes key information, including one or more items that will be reflected in one or more target travel product promotional statements T. The first prompt P1 then includes instructions for the first LLM 318 to generate one or more target travel product promotional statements T based on the key information, thereby allowing the first user to obtain a target travel product promotional statement T that reflects the key items desired by the first user.

[0086] In the system 1, the control circuit 212 of the second server 210 inputs a second prompt P2 to cause the second LLM 320 to score each of the one or more target travel product promotional phrases T included in the travel product promotional phrase information I5. This allows the first user to obtain the scoring results for the one or more target travel product promotional phrases T. Based on the scoring results, the first user can consider which of the one or more target travel product promotional phrases T to use for the travel product.

[0087] In the system 1, the second prompt P2 includes a scoring criterion, which includes at least one of specificity, amount of information, attractiveness, appeal, conciseness, grammatical accuracy, and originality. This allows the first user to consider which of the one or more target travel product promotional phrases T to use for the travel product based on the scoring result and the scoring criterion.

[0088] In the system 1, the control circuit 212 of the second server 210 selects one or more target travel product promotional phrases T based on the number of characters in the one or more target travel product promotional phrases T. This allows for the deletion of target travel product promotional phrases T that are too long or too short and are therefore inappropriate as promotional phrases for the travel product.

[0089] The system 1 can generate one or more promotional statements T for a target travel product that are suitable for the target travel product. More specifically, the target travel product information I1 includes at least one of the travel destination, country, season, airline, departure time, and arrival time of the target travel product. The control circuit 212 of the second server 210 extracts one or more pieces of acquired actual information I3 from the multiple pieces of actual information I2 based on at least one of the travel destination, country, season, airline, and departure time included in the target travel product information I1. Therefore, the control circuit 212 of the second server 210 can extract one or more pieces of acquired actual information I3 suitable for the target travel product from the multiple pieces of actual information I2. Therefore, the control circuit 212 of the second server 210 can generate one or more promotional statements T for the target travel product based on the one or more pieces of acquired actual information I3 suitable for the target travel product.

[0090] (Other embodiments) The system according to the present invention is not limited to System 1 and can be modified within the scope of the invention.

[0091] The third server 310 includes a first LLM 318 and a second LLM 320. However, the third server 310 may include the first LLM 318 but not the second LLM 320. In this case, the system 1 further includes a fourth server. The fourth server includes the second LLM 320.

[0092] It should be noted that the first LLM 318 and the second LLM 320 may be a common LLM.

The control circuit 212 (one or more computer control circuits / priority setting means 234) of the second server 210 may set the priority based on one or more pieces of acquired performance information I3. Specifically, the control circuit 212 of the second server 210 evaluates the contribution of the multiple items to the performance of the provision based on the performance of the provision of the one or more pieces of acquired performance information I3. The control circuit 212 of the second server 210 determines the priority of the multiple items based on the contribution of the multiple items to the performance of the provision and enters the priority in the first prompt P1.

[0095] 6 shows the operation of the control circuit 12 of the first terminal 10 and the control circuit 212 of the second server 210. However, the flowchart of FIG. 6 may be executed by the control circuit of one computer, or may be executed by the control circuits of three or more computers, for example.

[0096] The scoring criteria include at least two of the following scoring items: specificity, amount of information, attractiveness, appeal, conciseness, grammatical accuracy, and originality, and priorities may be set for two or more scoring items.

[0097] In the system 1, the number of promotional statements T for the target travel product is plural. However, the number of promotional statements T for the target travel product may be one or more.

However, the first prompt P1 may include instructions for causing the first LLM 318 to generate one or more promotional copy T for the target travel product.

[0100] The number of characters in the promotional text T for the target travel product in step S15 is not limited to 100. In step S15, the control circuit 212 of the second server 210 may delete promotional text T for the target travel product that is 50 characters or less. 50 characters is an example of the predetermined number of characters.

[0101] Travel products may be optional tours, themed travel products, eco-tours / sustainable travel, luxury travel, family / children's travel products, active tours, workation plans, etc. Optional tours are additional activities that can be selected during a stay at a tourist destination (e.g., night cruises, local guided tours). Themed travel products are trips specialized in a theme, such as gourmet food, art, history, or visiting filming locations. Eco-tours / sustainable travel are tours that allow you to experience environmental conservation activities or travel to enjoy nature. Luxury travel is a high-end individual travel product, with plans that include luxurious accommodations, private guides, and private vehicles. Family / children's travel products are plans that include amusement parks and zoos that the whole family can enjoy. Active tours are trips that allow you to experience active experiences, such as mountain climbing, trekking, diving, and skydiving.

[0102] The input information I4 includes the first prompt P1, the acquisition record information I3, and the target travel product information I1. However, the target travel product information I1 may be included in the first prompt P1. In this case, the input information I4 includes the first prompt P1 and the acquisition record information I3.
