[0038] The memory circuit 114 of server 110 stores the property overview information table shown in Figure 5. The property overview information table contains multiple property overview information I1, which includes details of the transaction property (property overview) that is the subject of the transaction. The transaction property is a real estate property introduced to the user by a real estate agent. The user can purchase the transaction property from the seller through the real estate agent, or rent the transaction property from the owner through the real estate agent. As a result, the memory circuit 114 of the server 110 stores multiple property overview information I1. The property overview information I1 contains multiple items K. Each of the multiple items K contains an item name and a content. The item names of the multiple items K are ID, information acquisition date, person in charge, company that brought the information, person in charge at the company that brought the information, consideration status, tag, sale price, building name, address, asset type, nearest station, completion date, site area, total floor area, owner, rentable area, land ownership type, floor area ratio, building ownership type, building coverage ratio, and group.

The building ownership form is the structure of the rights and ownership methods / mechanisms of the building on which the property is located. The building coverage ratio is the ratio of the building area that is permitted to the site area of ​​the property.

[0042] The control circuit 112 implements the functions of the server 110 by executing the program PG1 stored in the memory circuit 114. The control circuit 112 is a circuit that includes, for example, at least one of the following: ·CPU(Central Processing Unit) ·GPU(Graphic Processing Unit) ·ASIC(Application Specific Integrated Circuit) ·FPGA(Field Programmable Array)

[0043] As shown in Figure 4, the control circuit 112 includes, as functional blocks, a first property overview information acquisition means 120, a duplicate determination means 122, a duplicate information transmission control means 124, an information addition means 126, a change information acquisition means 128, a status change means 130, a priority determination instruction means 132, a priority information acquisition means 134, and a priority information transmission control means 136.

[0044] The network interface 116 is a transmitting and receiving circuit that controls communication between the server 110 and an external device. The external device is a user terminal 10.

[0045] [System 1 Operation] Next, the operation of System 1 will be explained with reference to the diagrams. Figures 6, 9, and 13 are flowcharts of the control circuit 12 of the user terminal 10 and the control circuit 112 of the server 110. Figure 7 is a diagram showing the property summary data D1. Figures 8, 10 to 12 are images displayed on the display 20 of the user terminal 10.

[0046] The control circuit 112 of the server 110 reads the program PG1 stored in the memory circuit 114, causing the control circuit 112 of the server 110 to execute the operations described below. The program PG1 causes the control circuit 112 of the server 110 to execute the following: first property overview information acquisition means 120, duplicate determination means 122, duplicate information transmission control means 124, information addition means 126, change information acquisition means 128, status change means 130, priority determination instruction means 132, priority information acquisition means 134, and priority information transmission control means 136. Furthermore, in the information processing method, the control circuit 112 of the server 110 executes the following: first property overview information acquisition means 120, duplicate determination means 122, duplicate information transmission control means 124, information addition means 126, change information acquisition means 128, status change means 130, priority determination instruction means 132, priority information acquisition means 134, and priority information transmission control means 136.

[0047] In System 1, the first or third process is performed. In the first process, property overview information I1 is newly registered in the property overview information table shown in Figure 5. In the second process, the search results for property overview information I1 are displayed on the user terminal 10. In the third process, the consideration status of property overview information I1 is changed.

[0048] First, the first process will be explained with reference to Figure 6. The user terminal 10 acquires the property summary data D1 shown in Figure 7 (step S1). The property summary data D1 is data from a document that summarizes the basic information and characteristics of the property being traded. In step S1, the broker's computer sends an email to the user terminal 10 with, for example, a PDF file of the property summary (hereinafter referred to as property summary data D1) attached. The network interface 16 of the user terminal 10 receives the email and outputs the email to the control circuit 12. As a result, the user terminal 10 acquires the property summary data D1.

[0049] Next, the control circuit 12 of the user terminal 10 displays the input image shown in Figure 8 on the display 20 (step S2). The input image shown in Figure 8 includes multiple boxes B1 for case data, and multiple boxes B2 and B3 for building data. Multiple boxes B1 are input boxes for the user to input case data. The case data consists of multiple first items K1 in the property overview information I1 shown in Figure 5, for the user to manage the property overview information I1. The item names of the multiple first items K1 are, for example, information acquisition date, person in charge, company bringing the property, person in charge at the company bringing the property, consideration status, tag, and sale price. Multiple boxes B2 are input boxes for the user to input building data. The building data consists of multiple second items K2 related to the transaction property in the property overview information I1 shown in Figure 5. The item names of the multiple second items K2 are building name, address, asset type, nearest station, completion date, site area, total floor area, owner, leasable area, land ownership type, floor area ratio, building ownership type, and building coverage ratio. Box B3 is an input box for the user to enter property details data D1.

[0050] In step S2, the user operates the input unit 26 of the user terminal 10 to input the contents of multiple first items K1 into each of the multiple boxes B2 of the case data. In this embodiment, the information input date is April 20, 2025, the person in charge is Tanaka Jiro, the submitting company is JJJ, the submitting company's representative is KKK, the review status is not yet reviewed, the tag is , and the purchase price is 125,000,000,000 yen. As a result, the control circuit 112 of the user terminal 10 acquires input information I2 indicating the contents of multiple first items K1 entered by the user (step S3).

[0051] Next, the control circuit 12 of the user terminal 10 transmits input information I2 to the server 110 via the network interface 16 (step S4). In this specification, when the control circuit transmits information via the network interface, it means that the control circuit instructs the network interface to transmit information. Accordingly, the network interface 116 of the server 110 receives the input information I2 and outputs the input information I2 to the control circuit 112. As a result, the control circuit 112 of the server 110 acquires the input information I2 (step S101).

[0052] Next, the user inputs the property summary data D1 into box B3 of the input image shown in Figure 8 by operating the input unit 26 of the user terminal 10. Accordingly, the control circuit 12 of the user terminal 10 transmits the property summary data D1 to the server 110 via the network interface 16 (step S5). Accordingly, the network interface 116 of the server 110 receives the property summary data D1 and outputs the property summary data D1 to the control circuit 112. As a result, the control circuit 112 of the server 110 acquires the property summary data D1 (step S102).

[0053] Next, the control circuit 112 of the server 110 extracts extracted information I3 from the property summary data D1 (step S103). More specifically, the property summary data D1 is data from a document that summarizes the basic information and characteristics of the property being traded. Therefore, the property summary data D1 contains information corresponding to the content of the second item K2 of the building data. So, the control circuit 112 of the server 110 converts the property summary data D1 into text information using OCR (Optical Character Recognition). Then, the control circuit 112 of the server 110 extracts text information from the text information of the property summary data D1 that leads to the item name and content of the second item K2. For example, the control circuit 112 of the server 110 extracts "Building Name" from the property summary data D1 as the item name of the second item K2, and also extracts "AAA Roppongi" from the property summary data D1 as the content of the second item K2. Furthermore, the control circuit 112 of the server 110 also extracts other character information from the property summary data D1 as the item name and content of the second item K2. Then, the control circuit 112 of the server 110 generates extracted information I3 which includes the item names and content of the multiple extracted second items K2. In this way, the control circuit 112 of the server 110 (first property summary information acquisition means 120) acquires first property summary information I11 which includes the content of the first transaction property that is the subject of the transaction from the user terminal 10 in steps S101 to S103. In this specification, the first property summary information I11 includes input information I2 and extracted information I3. Since the extracted information I3 is generated based on the information extracted by the server 110 from the property summary data D1 acquired from the user terminal 10, it corresponds to the first property summary information I11 acquired from the user terminal 10.

[0054] Next, the control circuit 112 of the server 110 transmits the extracted information I3 to the user terminal 10 via the network interface 116 (step S104). Accordingly, the network interface 16 of the user terminal 10 receives the extracted information I3 and outputs the extracted information I3 to the control circuit 12. As a result, the control circuit 12 of the user terminal 10 acquires the extracted information I3 (step S6).

[0055] Next, the control circuit 12 of the user terminal 10 displays an input image on the display 20 in which the contents of each of the multiple first items K1 included in the input information I2 are written in box B1, and the contents of each of the multiple second items K2 included in the extracted information I3 are written in multiple boxes B2 (step S7). In step S7, the user can give an instruction to generate new first property summary information I11 of the transaction property using the displayed input image. Specifically, the user presses the "Generate Record" button 400 provided on the input screen by operating the input unit 26 of the user terminal 10. As a result, the control circuit 12 of the user terminal 10 sends property summary information generation instruction information I4, which includes an instruction to generate new first property summary information I11 of the transaction property, to the server 110 via the network interface 16 (step S8). Accordingly, the network interface 116 of the server 110 receives the property summary information generation instruction information I4 and outputs the property summary information generation instruction information I4 to the control circuit 112. As a result, the control circuit 112 of the server 110 acquires the property summary information generation instruction information I4 (step S105).

[0056] Next, the control circuit 112 of the server 110 generates the first property summary information I11 based on the property summary information generation instruction information I4 (step S106). More specifically, the control circuit 112 of the server 110 converts the contents of the multiple first items K1 included in the input information I2 acquired in step S101 and the contents of the multiple second items K2 included in the extracted information I3 into the contents of the multiple first items K1 and the multiple second items K2 of the first property summary information I11.

[0057] Next, the control circuit 112 (duplicate determination means 122) of the server 110 determines whether a duplicate state has occurred in which the first transaction property included in the first property summary information I11 exists among the transaction properties included in the multiple property summary information I1 stored in the memory circuit 114 of the server 110 (step S107). More specifically, in the duplicate state determination process, the control circuit 112 of the server 110 determines whether a duplicate state has occurred by comparing the contents of multiple items K included in the multiple property summary information I1 with the contents of multiple items K included in the first property summary information I11. In this embodiment, the control circuit 112 of the server 110 determines whether a duplicate state has occurred by determining whether the contents of the addresses included in the multiple property summary information I1 match the contents of the addresses included in the first property summary information I11. In this embodiment, the control circuit 112 of the server 110 determines whether there is a property summary information I1 that contains the same address as the address of the first property summary information I11, "Minato-ku, Tokyo...". If a duplicate state has occurred, this process proceeds to step S108. If no duplicate conditions occur, the process proceeds to step S109.

[0058] If a duplication condition occurs, the control circuit 112 of the server 110 records duplication information I5, indicating that a duplication condition has occurred, in the first property summary information I11 (step S108). Hereinafter, one or more property summary information items that include the contents of the first transaction property among multiple property summary information items I1 are defined as one or more second property summary information items I12. That is, one or more second property summary information items I12 are property summary information items I1 that overlap with the first property summary information item I11. Therefore, the control circuit 112 of the server 110 records the IDs of one or more second property summary information items I12 that overlap with the first property summary information item I11 in the contents of the group of first property summary information item I11 shown in Figure 5. Thus, the duplication information I5 corresponds to the contents of the group of first property summary information item I11 shown in Figure 5. If multiple second property summary information I12s overlap with the first property summary information I11, the control circuit 112 of the server 110 records the ID of the second property summary information I12 that has the oldest information acquisition date among the multiple second property summary information I12s. In this embodiment, property summary information I1 (second property summary information I12) with ID "1" has the oldest information acquisition date among the multiple second property summary information I12s. Therefore, the control circuit 112 of the server 110 records "1" in the group content of the first property summary information I11. As a result, the control circuit 112 of the server 110 (information addition means 126) includes in the overlap information I5 that the first property summary information I11 and one or more second property summary information I12s belong to a specific group. After this, the process proceeds to step S109.

[0059] In step S109, the control circuit 112 of the server 110 records the first property summary information I11 in the property summary information table shown in Figure 5 (step S109). This completes the process.

[0060] Next, the second process will be explained with reference to Figure 9. The control circuit 12 of the user terminal 10 displays the search image shown in Figure 10 on the display 20 (step S11). The search image shown in Figure 10 includes a search condition input section P1 and a search result display section P2. The search condition input section P1 includes multiple boxes B4. The search result display section P2 includes multiple property summary information I1. However, since no search has been performed at the time step S11 is executed, the search result display section P2 is blank. The user inputs search conditions into the multiple boxes B4 by operating the input section 26 of the user terminal 10. In this embodiment, the user inputs "Roppongi" into the keyword box B4. As a result, the control circuit 12 of the user terminal 10 obtains search condition information I7 indicating the search conditions entered by the user. In this embodiment, the search condition information I7 includes "Roppongi" as the search keyword.

[0061] Next, the control circuit 12 of the user terminal 10 transmits the search condition information I7 to the server 110 via the network interface 16 (step S13). Accordingly, the network interface 116 of the server 110 receives the search condition information I7 and outputs the search condition information I7 to the control circuit 112. As a result, the control circuit 112 of the server 110 acquires the search condition information I7 (step S111).

[0062] Next, the control circuit 112 of the server 110 extracts one or more property summary information I1 that match the search criteria from the property summary information table based on the search criteria information I7 (step S112). In this embodiment, the control circuit 112 of the server 110 extracts one or more property summary information I1 that include the keyword "Roppongi" included in the search criteria information I7 from the property summary information table as a search result.

[0063] Next, the control circuit 112 of the server 110 transmits one or more property summary information I1, which are the search results, to the user terminal 10 via the network interface 116 (step S113). Here, if a duplicate state occurs, the one or more property summary information I1 includes a first property summary information I11 and one or more second property summary information I12. Since the first property summary information I11 and one or more second property summary information I12 belong to a specific group, they include duplicate information I5 with the same content. Duplicate information I5 is an ID recorded in the group content of the property summary information table shown in Figure 5. In this embodiment, the one or more property summary information I1, which are the search results, includes a first property summary information I11 containing an ID of "1" and one or more second property summary information I12. Thus, if a duplicate state occurs, the control circuit 112 of the server 110 (duplicate information transmission control means 124) transmits duplicate information I5, indicating that a duplicate state has occurred, to the user terminal 10 via the network interface 116. Accordingly, the network interface 16 receives one or more property summary information I1 as a search result from the user terminal 10 and outputs the one or more property summary information I1 as a search result to the control circuit 12. As a result, the control circuit 12 of the user terminal 10 acquires one or more property summary information I1 as a search result (step S14). As a result, the control circuit 12 of the user terminal 10 acquires one or more duplicate information I5 contained in each of the one or more property summary information I1 as a search result.

[0064] Next, the control circuit 12 of the user terminal 10 displays the search screen shown in Figure 10 on the display 20, which includes a list of one or more property summary information I1, based on one or more duplicate pieces of information I5 (step S15). In step S15, the search result display unit P2 included in the search screen shown in Figure 10 includes one or more property summary information I1, which are the search results. However, the first property summary information I11 and one or more second property summary information I12 are duplicates of each other. Therefore, the control circuit 12 of the user terminal 10 identifies the first property summary information I11 and one or more second property summary information I12 that are duplicates of each other based on the one or more duplicate pieces of information I5. Then, the control circuit 12 of the user terminal 10 displays one of the first property summary information I11 and one or more second property summary information I12 as a representative on the display 20.

[0065] Furthermore, in step S15, the control circuit 12 of the user terminal 10 displays the number of duplicates, which is the total number of duplicates in the first property summary information I11 and one or more second property summary information I12, on the display 20, based on the duplicate information I5 contained in the first property summary information I11 and one or more second property summary information I12. The duplicate information I5 is the content of item K of the group. In this embodiment, the control circuit 12 of the user terminal 10 displays the total number of duplicates in the first property summary information I11 and one or more second property summary information I12 for which "1" is recorded in the content of item K of the group, on the display 20. In this embodiment, the control circuit 12 of the user terminal 10 displays "6 items" in the duplicate column. The control circuit 12 of the user terminal 10 also displays the number of duplicates for other property summary information I1 on the display 20.

[0066] Furthermore, in step S15, if the number of duplicates exceeds a predetermined number, the control circuit 12 of the user terminal 10 makes the display of the first property summary information I11 and one or more second property summary information I12 different from the display of one or more property summary information I1 excluding the first property summary information I11 and one or more second property summary information I12. In this embodiment, the predetermined number is 5. The control circuit 12 of the user terminal 10 displays the characters of the first property summary information I11 and one or more second property summary information I12 on the display 20 more faintly than the characters of one or more property summary information I1 excluding the first property summary information I11 and one or more second property summary information I12.

[0067] Furthermore, each of the one or more property summary information I1 included in the search image shown in Figure 10 has an "Open" button. By operating the input unit 26 of the user terminal 10, the user can select one of the "Open" buttons of the one or more property summary information I1 included in the search image shown in Figure 10. As a result, the control circuit 12 of the user terminal 10 displays the search screen shown in Figure 11 on the display 20, which includes a list of mutually overlapping first property summary information I11 and one or more second property summary information I12. The search image shown in Figure 11 includes the contents of the property summary information I1 corresponding to the "Open" button selected by the user (i.e., mutually overlapping first property summary information I11 and one or more second property summary information I12).

[0068] Furthermore, the user can select one of the one or more property summary information I1 included in the search image shown in Figure 10 by operating the input unit 26 of the user terminal 10. If the property summary information I1 selected by the user includes a first property summary information I11 and one or more second property summary information I12 that overlap with each other, the control circuit 12 of the user terminal 10 identifies the first property summary information I11 and one or more second property summary information I12 that overlap with each other based on one or more overlapping information I5. Then, as shown in Figure 12, the control circuit 12 of the user terminal 10 displays a list of the first property summary information I11 and one or more second property summary information I12 belonging to a specific group on the display 20. At this time, the control circuit 12 of the user terminal 10 arranges the first property summary information I11 and one or more second property summary information I12 in order of information acquisition date. Specifically, the control circuit 12 of the user terminal 10 positions the first property summary information I11 and one or more second property summary information I12 with older information acquisition dates at the top, and the first property summary information I11 and one or more second property summary information I12 with newer information acquisition dates at the bottom. This completes the process.

[0069] Next, the third process will be explained with reference to Figure 13. The control circuit 12 of the user terminal 10 displays the search image shown in Figure 12 on the display 20 (step S21). The search image shown in Figure 12 includes a first property summary information I11 and one or more second property summary information I12 belonging to a specific group. The user decides on a third property summary information I13 whose review status will be changed from the first property summary information I11 and one or more second property summary information I12 belonging to a specific group. Then, the user changes the review status of the third property summary information I13 from "not yet considered" to "under consideration" by operating the input unit 26 of the user terminal 10. In this embodiment, the user changes the review status of property summary information I1 (third property summary information I13) whose submitting company is "JJJ" from "not yet considered" to "under consideration" by operating the input unit 26 of the user terminal 10. As a result, the control circuit 12 of the user terminal 10 obtains change information I6 indicating that the consideration status (status) included in the first property summary information I11 and the third property summary information I13, which is one or more second property summary information I12 belonging to a specific group, has been changed (step S22).

[0070] Next, the control circuit 12 of the user terminal 10 transmits change information I6 to the server 110 via the network interface 16 (step S23). Accordingly, the network interface 116 of the server 110 receives the change information I6 and outputs the change information I6 to the control circuit 112. As a result, the control circuit 112 (change information acquisition means 128) of the server 110 acquires the change information I6 from the user terminal 10 (step S121).

[0071] Next, the control circuit 112 of the server 110 updates the review status of the third property summary information I13 included in the property summary information table based on the change information I6 (step S122). More specifically, the change information I6 indicates that the review status of the third property summary information I13 has changed from "not yet reviewed" to "under review". Therefore, the control circuit 112 of the server 110 changes the review status of the third property summary information I13 in the property summary information table shown in Figure 5 from "not yet reviewed" to "under review". In this embodiment, the control circuit 112 of the server 110 changes the review status of property summary information I1, whose ID is "51", from "not yet reviewed" to "under review".

[0072] Next, the control circuit 112 of the server 110 identifies property summary information I1, which belongs to the same specific group as the third property summary information I13, from the property summary information table (step S123). In step S123, the control circuit 112 of the server 110 identifies one or more property summary information I1s from the property summary information table, excluding the third property summary information I13, from the first property summary information I11 and one or more second property summary information I12s included in the search image shown in Figure 12.

[0073] Next, the control circuit 112 of the server 110 changes the status of one or more property summary information I1 identified in step S123 based on the change information I6 (step S124). That is, the control circuit 112 of the server 110 (status change means 130) changes the status of one or more property summary information I1, excluding the third property summary information I13, from the first property summary information I11 and one or more second property summary information I12 belonging to the specified group, based on the change information I6. As a result, the review status of the first property summary information I11 and one or more second property summary information I12 belonging to the specified group is changed all at once. This completes the process.

[0074] [effect] According to Server 110, even if the properties being traded overlap, transactions involving multiple properties can be properly managed. More specifically, in a system that manages property overview information related to transactions of properties, the same property may be introduced by multiple real estate agents. In other words, multiple property overview entries may overlap. In such cases, the person in charge may mistakenly believe that the multiple property overview entries pertain to different properties and may consider each of the multiple property overview entries as a transaction.

[0075] Therefore, the control circuit 112 of the server 110 determines whether a duplication state has occurred in which the first transaction property included in the first property summary information I11 exists among the transaction properties included in the multiple property summary information I1 stored in the memory circuit 114. If a duplication state has occurred, the control circuit 112 of the server 110 sends duplication information I5 to the user terminal 10 indicating that a duplication state has occurred. This allows the user to recognize that a duplication state has occurred. As a result, the user is less likely to mistakenly believe that the multiple property summary information I1 are information about different transaction properties, and the likelihood of the user considering a transaction for each of the multiple property summary information I1 is reduced. Thus, according to the server 110, transactions of multiple properties can be appropriately managed even when the properties being traded overlap.

[0076] In server 110, the control circuit 112 determines whether a duplicate situation has occurred by determining whether the content of the addresses included in multiple property summary information I1 matches the content of the addresses included in the first property summary information I11. The address is an element that can identify the transaction property. Therefore, by using the address in the duplicate situation determination process, the accuracy of the duplicate situation determination is improved.

[0077] In server 110, the control circuit 112 of server 110 includes in the duplicate information I5 that the first property summary information I11 and one or more second property summary information I12 belong to a specific group. As a result, the user terminal 10 can determine, based on the duplicate information I5, that the first property summary information I11 and one or more second property summary information I12 belong to a specific group. Therefore, the user can recognize that the first property summary information I11 and one or more second property summary information I12 are related to the same transaction property.

[0078] According to server 110, users can determine which property summary information I1 transaction should take priority. More specifically, there may be multiple users in an organization such as a company. In this case, multiple users may acquire multiple property summary information I1 for the same transaction property. Generally, the transaction of the property summary information I1 acquired first by the organization takes priority. Therefore, server 110 includes the date (information acquisition date) on which each of the first property summary information I11 and one or more second property summary information I12 was notified to the user terminal 10. As a result, if a duplicate occurs, the user can determine which of the duplicate first property summary information I11 and one or more second property summary information I12 should take priority by checking the information acquisition dates of the duplicate first property summary information I11 and one or more second property summary information I12.

[0079] On the server 110, the control circuit 12 of the user terminal 10 displays a list of first property summary information I11 and one or more second property summary information I12 belonging to a specific group on the display 20, as shown in Figure 12. This allows the user to easily compare the first property summary information I11 and one or more second property summary information I12 that overlap with each other.

[0080] According to server 110, users can easily change the review status of the first property summary information I11 and one or more second property summary information I12 that overlap with each other. More specifically, the control circuit 112 of server 110 obtains change information I6 from the user terminal 10 indicating that the review status (status) included in the third property summary information I13, which is one of the first property summary information I11 and one or more second property summary information I12 belonging to a specific group, has been changed. The control circuit 112 of the server 110 then changes the status of one or more property summary information I1s, excluding the third property summary information I13, from the first property summary information I11 and one or more second property summary information I12 belonging to a specific group, based on the change information I6. As a result, if a user changes the status of the third property summary information I13 by operating the input unit 26 of the user terminal 10, the status of the first property summary information I11 and one or more second property summary information I1s, excluding the third property summary information I13, will be automatically changed. Consequently, the user can easily change the review status of the first property summary information I11 and one or more second property summary information I12 that overlap with each other.

[0081] As shown in Figure 10, the control circuit 112 of server 110 displays a list of multiple property summary information I1, including first property summary information I11 and one or more second property summary information I12 that overlap with each other. Based on the overlap information I5, it also displays the overlap count, which is the total number of first property summary information I11 and one or more second property summary information I12 that overlap with each other. This allows the user to know the overlap count.

[0082] According to the server 110, as shown in Figure 10, the control circuit 12 of the user terminal 10, when the number of duplicates exceeds a predetermined number, sets the display mode of the first property summary information I11 and one or more second property summary information I12 that are duplicates of each other to be different from the display mode of one or more property summary information I1 that are not duplicates of each other. This allows the user to easily recognize property summary information I1 with many duplicates. If a large number of duplicates indicates that the transaction property is popular, the control circuit 12 of the user terminal 10 should set the display mode of the first property summary information I11 and one or more second property summary information I12 that are duplicates of each other to be more prominent than the display mode of one or more property summary information I1 that are not duplicates of each other. If a high number of duplicates indicates that the property being traded is unpopular, the control circuit 12 of the user terminal 10 should set the display modes of the first property summary information I11 and one or more second property summary information I12 that overlap with each other to be less conspicuous than the display modes of one or more property summary information I1 that do not overlap with the first property summary information I11 and one or more second property summary information I12.

[0083] (First variation) The first modified system 1a will be described below with reference to the drawings. Figure 14 is a block diagram of systems 1a and 1b. Figure 15 is a flowchart showing the actions performed by the control circuit 12 of the user terminal 10 and the control circuit 112 of the server 110.

[0084] System 1a differs from System 1 in that it further includes a database server 210. The memory circuit of the database server 210 stores multiple property details I31, which include the property's contents. The operating company that operates Server 110 and Database Server 210 collects information on multiple properties. The operating company then records multiple property details I31, which include the contents of the properties for which information has been collected, in the memory circuit of the database server 210. Each of the multiple property details I31 includes, for example, the building name, address, asset type, nearest station, completion date, site area, coordinates / total floor area, owner, leasable area, land ownership type, floor area ratio, building ownership type, building coverage ratio, etc.

[0085] Next, the operation of system 1a will be described. Steps S1-S8, S101-S106, S108, and S109 in Figure 15 are the same as steps S1-S8, S101-S106, S108, and S109 in Figure 6, so their explanation will be omitted.

[0086] The control circuit 112 of server 110 updates the first property summary information I11 based on multiple property details I31 (step S201). More specifically, in step S201, the control circuit 112 of server 110 obtains property details I31, which includes the building name or address of the first property summary information I11 generated in step S106, from the database server 210. The control circuit 112 of server 110 then compares the contents of the obtained property details I31 with the contents of multiple second items K2 of the first property summary information I11. The control circuit 112 of server 110 then matches one or more second items K2 of the first property summary information I11 that do not match the contents of the obtained property details I31 to the contents of the obtained property details I31.

[0087] Next, the control circuit 112 of the server 110 determines whether a duplication state has occurred in which the first transaction property included in the first property summary information I11 updated in step S201 exists among the transaction properties included in the multiple property summary information I1 stored in the memory circuit 114 of the server 110 (step S202). More specifically, in the duplication state determination process, the control circuit 112 of the server 110 determines whether a duplication state has occurred by comparing the contents of multiple items K included in the multiple property summary information I1 with the contents of multiple items K included in the first property summary information I11. In this modified example, the control circuit 112 of the server 110 determines whether a duplication state has occurred by determining whether the contents of the addresses included in the multiple property summary information I1 match the contents of the addresses included in the first property summary information I11. In this embodiment, the control circuit 112 of the server 110 determines whether there is a property summary information I1 that contains the same address as the address of the first property summary information I11, "Minato-ku, Tokyo...". If a duplication state has occurred, this process proceeds to step S108. If no duplicate conditions occur, the process proceeds to step S109.

[0088] According to system 1a, the first property overview information I11 is updated based on multiple property details I31. This improves the accuracy of the first property overview information I11. As a result, the control circuit 112 of server 110 can more accurately determine whether or not a duplication state has occurred.

[0089] (Second variation) Below, we will describe system 1b, which relates to the second modified example, with reference to the drawings. Figure 16 is a flowchart showing the operations performed by the control circuit 12 of the user terminal 10, the control circuit 112 of the server 110, and the control circuit of the LLM server 310.

[0090] System 1b differs from System 1 in that it further includes an LLM server 310. The LLM server 310 is equipped with LLM (Large Language Models). The LLM server 310 determines the priority of overlapping first property summary information I11 and one or more second property summary information I12. Priority is a parameter that indicates which of the overlapping first property summary information I11 and one or more second property summary information I12 the user should prioritize considering.

[0091] Next, the operation of system 1b will be described. The control circuit 112 of server 110 sends mutually overlapping first property summary information I11 and one or more second property summary information I12, as well as a prompt, to LLM server 310 via the network interface 116 (step S131). The prompt is an instruction to cause LLM to generate priority information I32 indicating the priority of mutually overlapping first property summary information I11 and one or more second property summary information I12. The prompt describes determining the priority of mutually overlapping first property summary information I11 and one or more second property summary information I12 based on the differences between them. The prompt may indicate, for example, that the priority of the first property summary information I11 or one or more second property summary information I12 has an older information acquisition date, or that the priority of the first property summary information I11 or one or more second property summary information I12 has a higher selling price. Accordingly, the LLM server 310 obtains priority information I32 (step S301).

[0092] The LLM server 310 generates priority information I32 indicating the priority of the first property summary information I11 and the one or more second property summary information I12 by inputting the mutually overlapping first property summary information I11 and one or more second property summary information I12, as well as prompts to the LLM (step S302). In this way, the control circuit 112 (priority determination instruction means 132) of the server 110 inputs the mutually overlapping first property summary information I11 and one or more second property summary information I12 to the LLM, causing the LLM to determine the priority of the first property summary information I11 and one or more second property summary information I12.

[0093] Next, the LLM server 310 transmits priority information I32 to the server 110 (step S303). Accordingly, the network interface 116 of the server 110 receives the priority information I32 and outputs the priority information I32 to the control circuit 112. As a result, the control circuit 112 (priority information acquisition means 134) of the server 110 acquires the priority information I32 indicating the priority from the LLM server 310 (step S132).

[0094] Next, the control circuit 112 (priority information transmission control means 136) of the server 110 transmits priority information I32 to the user terminal 10 via the network interface 116 (step S133). Accordingly, the network interface 16 of the user terminal 10 receives the priority information I32 and outputs the priority information I32 to the control circuit 12. As a result, the control circuit 12 of the user terminal 10 acquires the priority information I32 (step S31). Then, the control circuit 12 of the user terminal 10 displays the priority information I32 on the display 20 (step S32). This completes the process.

[0095] According to system 1b, the user can easily determine which of the overlapping transactions in the first property summary information I11 and one or more second property summary information I12 should take priority.

[0096] (Other embodiments) The system according to the present invention is not limited to systems 1, 1a, and 1b, but can be modified within the scope of its gist. Furthermore, the configurations of systems 1, 1a, and 1b may be combined in any way.

[0097] When the control circuit 12 of the user terminal 10 displays a list of first property summary information I11 and one or more second property summary information I12 on the display 20, this includes both the enumeration of the first transaction property and its contents in the first property summary information I11 and one or more second property summary information I12, and the enumeration of the first transaction property in the first property summary information I11 and one or more second property summary information I12. When the first transaction property in the first property summary information I11 and one or more second property summary information I12 is enumerated, the user can select either the first property summary information I11 or one or more second property summary information I12 by operating the input unit 26 of the user terminal 10. The control circuit 12 of the user terminal 10 displays the contents of either the first property summary information I11 or one or more second property summary information I12 selected by the user. This allows the user to confirm the contents of either the first property summary information I11 or one or more second property summary information I12.

[0098] The control circuit 112 of server 110 obtains the extracted information I3 by generating it from the property summary data D1. However, the control circuit 112 of server 110 may also obtain the contents of the property summary data D1 entered by the user using the input unit 26 of the user terminal 10. Alternatively, the control circuit 112 of server 110 may also obtain the contents of the property summary data D1 entered by the staff of the server 110's operating company.

[0099] Please note that the property details data D1 may be in the form of an email instead of a PDF file.

[0100] Furthermore, the user can select one of the one or more property summary information I1 included in the search image shown in Figure 10 by operating the input unit 26 of the user terminal 10. As a result, the control circuit 12 of the user terminal 10 displays a list of first property summary information I11 and one or more second property summary information I12 belonging to a specific group on the display 20, as shown in Figure 12. At this time, the control circuit 12 of the user terminal 10 may display the property summary information I1 selected by the user from among the first property summary information I11 and one or more second property summary information I12 at the top of the list. The control circuit 12 of the user terminal 10 may then display the property summary information I1 that was not selected by the user from among the first property summary information I11 and one or more second property summary information I12 below the property summary information I11 selected by the user.

[0101] Furthermore, when displaying the search images shown in Figure 12, the control circuit 12 of the user terminal 10 may position the first property summary information I11 and one or more second property summary information I12 with the oldest information acquisition date at the top, and may also highlight the first property summary information I11 and one or more second property summary information I12 with the oldest information acquisition date. This allows the user to identify transactions that should be prioritized.

[0102] Furthermore, when displaying the search images shown in Figure 12, the control circuit 12 of the user terminal 10 may narrow down the first property summary information I11 and one or more second property summary information I12 to be displayed on the display 20 by having the user input conditions. The conditions may be, for example, the status of under consideration. If the user selects "Under Consideration," the control circuit 12 of the user terminal 10 may display the first property summary information I11 and one or more second property summary information I12 that have the "Under Consideration" status on the display 20.

[0103] When displaying the search image shown in Figure 10, the control circuit 12 of the user terminal 10 may group multiple property summary information I1 that satisfy specific conditions and display them on the display 20. These specific conditions include, for example, that the transaction price falls within a predetermined price range and that the asset type is the same. Furthermore, the control circuit 12 of the user terminal 10 may narrow down which of the grouped property summary information I1 to display on the display 20 by having the user input conditions. Grouping multiple property summary information I1 and displaying them on the display means, for example, displaying multiple property summary information I1 in the same color text on the display 20, or enclosing multiple property summary information I1 in a single frame on the display 20. In other words, the display manner of the grouped multiple property summary information I1 must differ from the display manner of one or more other property summary information I1. The control circuit 12 of the user terminal 10 may also highlight the property summary information I1 with the highest priority among the grouped multiple property summary information I1.

[0104] Furthermore, if the control circuit 112 of the server 110 determines in step S107 that a duplication state has occurred, it may notify the user terminal 10 that a duplication state has occurred. More specifically, the intermediary distributes a large number of property summary data D1. If the user is a company, the user includes multiple contact persons (for example, a first contact person and a second contact person). Therefore, the second contact person may obtain property summary data D1 with the same content as the property summary data D1 obtained by the first contact person. However, for example, only the photograph in the property summary data D1 obtained by the second contact person may differ from the property summary data D1 obtained by the first contact person. In such a case, if the control circuit 112 of the server 110 determines in step S107 that a duplication state has occurred, it may notify the user terminal 10 that a duplication state has occurred. In response to the notification, the control circuit 12 of the user terminal 10 may change the display format of the property summary information I1 corresponding to the property summary data D1 obtained by the second contact person to a different format from the display format of other property summary information.

[0105] Furthermore, the control circuit 112 of the server 110 may, each time the control circuit 12 of the user terminal 10 displays a search image on the display 20, refer to the contents of item K of the group of multiple property summary information I1 and display the multiple property summary information I1 in groups. Also, each time the control circuit 12 of the user terminal 10 reloads a search image, the control circuit 112 of the server 110 may, each time the control circuit 12 of the user terminal 10 reloads a search image, refer to the contents of item K of the group of multiple property summary information I1 and display the multiple property summary information I1 in groups.

[0106] Furthermore, there is a possibility that the property overview information I1 may be updated frequently. For example, the price of a property or the exterior photo of a property may be updated. In such cases, the content of item K in the group of property overview information I1 will not change. However, while the priority of property overview information I1 changes when the price of a property changes, the priority of property overview information I1 does not change when the exterior photo of a property changes. Therefore, in systems 1, 1a, and 1b, property overview information I1 may also include a priority item K. The control circuit 112 of server 110 may classify multiple property overview information I1 based on the content of item K in the group, and then further classify multiple property overview information I1 within each group into subgroups based on the content of the priority item K. Note that property overview information I1 may also be classified into subgroups by items K other than priority.

[0107] Note that there are variations in the spelling of the first address entered by the user and the first address read by OCR. Therefore, the control circuit 112 of the server 110 may correct the first address entered by the user and the first address read by OCR. In this case, the memory circuit 114 of the server 110 stores multiple property summary information I1, including the first address entered by the user, the first address read by OCR, and the second address with the spelling variations corrected. The control circuit 112 of the server 110 may then determine whether or not a duplication situation has occurred by determining whether the content of the first address or the second address included in the multiple property summary information I1 matches the content of the address included in the first property summary information I11.
