(2) Second action: System 1 changes the displayed content from input image 800 in Figure 18 to input image 800 in Figure 25. (3) Third action: System 1 generates data for the property summary.

[0075] (1) First operation First, let's explain the overview of the first operation of System 1. The input image 900 shown in Figure 18 contains multiple items. Specifically, the input image 900 includes property registration no., property name, price, type, current status, frontage land value, address, lot number, public transportation, other, registered area, measured area, rights, land category, private road burden, road, urbanization classification, zoning, building coverage ratio, floor area ratio, fire prevention, height restrictions, other restrictions, type, structure / size, total floor area, construction date, inspection certificate, construction company, income, expenses, net profit, and remarks.

[0076] Traditionally, real estate sellers would input the property name, price, address, income, expenses, net profit, and remarks. In practice, real estate agents (users) interview the sellers and then input the property name, price, address, income, expenses, net profit, and remarks. In addition, real estate agents (users) input the property registration number, type, current status, frontage land value, lot number, public transportation, other information, registered area, measured area, rights, land category, private road burden, road, urbanization classification, zoning, building coverage ratio, floor area ratio, fire prevention, height restrictions, other restrictions, type, structure / size, total floor area, construction date, inspection certificate, and construction company.

[0077] Meanwhile, in System 1, the control circuit 12 of terminal 10 displays the input image 800 shown in Figure 18 on the display 20. The input image 800 includes an input unit 810 and an information display unit 820. The input unit 810 includes multiple input boxes. The information display unit 820 displays one of the following: real estate information I1, certified copy information I2, road register information I3, map information I4, land price information I5, and urban planning information I6, which are used to generate data for the property summary document. Real estate information I1, land register information I2, road register information I3, map information I4, land value information I5, and urban planning information I6 are examples of acquired information I23. Therefore, one of the acquired information I23 will be displayed on the information display unit 820. However, in the initial state, nothing is displayed on the information display unit 820.

[0078] The user inputs the property name, address, and total price (price) in the image shown in Figure 18 by operating the control unit 26 of the terminal 10. The control circuit 12 of the terminal 10 transmits the user input information I0, including the property name, address, and total price (price), to the management server 110.

[0079] The control circuit 112 of the management server 110 collects information based on user input information I0. Specifically, the control circuit 112 of the management server 110 acquires real estate information I1 (acquired information I23) shown in Figure 5 from the real estate information DB 114a of the memory circuit 114. The control circuit 112 of the management server 110 acquires copy information I2 (acquired information I23) shown in Figure 7 from the copy server 210. The control circuit 112 of the management server 110 acquires road ledger information I3 (acquired information I23) shown in Figure 9 from the road ledger server 310. The control circuit 112 of the management server 110 acquires map information I4 (acquired information I23) shown in Figure 11 from the map server 410. The control circuit 112 of the management server 110 acquires road value information I5 (acquired information I23) shown in Figure 13 from the road value server 510. The control circuit 112 of the management server 110 acquires urban planning information I6 (acquired information I23) shown in Figure 15 from the urban planning server 610. The control circuit 112 of the management server 110 acquires photo information I7 from the photo server 710.

[0080] Then, the control circuit 112 of the management server 110 generates display information I53 for displaying the input image 800 shown in Figure 18 on the display 20 of the terminal 10, based on the real estate information I1, the certified copy information I2, the road register information I3, the map information I4, the land value information I5, the urban planning information I6, and the photographic information I7.

[0081] Next, the details of the first operation of System 1 will be explained with reference to the diagrams. Figures 20 to 23 are flowcharts of the first operation performed by the control circuit 12 of terminal 10 and the control circuit 112 of management server 110. Figure 19 is a diagram showing the correspondence table.

[0082] The control circuit 112 of the management server 110 reads program PG1 stored in the memory circuit 114. Program PG1 is a program that instructs the control circuit 112 of the management server 110 to execute a digital document manufacturing method. These programs PG1 cause the control circuit 112 of the management server 110 to execute the operations described below. Program PG1 causes the control circuit 112 of the management server 110 to execute the first display information generation means 112a, the first base information acquisition means 112b, the first digital document generation information generation means 112c, the first correspondence relationship information generation means 112d, the first base information identification means 112e, the first determination information acquisition means 112f, the determination means 112g, the second display information generation means 112h, the second base information acquisition means 112i, the second digital document generation information generation means 112j, the second correspondence relationship information generation means 112k, the second determination information acquisition means 112l, the layout information acquisition means 112m, the first digital document generation means 112n, the update means 112o, and the photo information acquisition means 112p.

[0083] First, the control circuit 12 of terminal 10 displays the input image 800 shown in Figure 18 on the display 20. However, at this point, the acquired information I23 is not displayed on the information display unit 820. The user inputs the property name and total price in the image shown in Figure 18 by operating the operation unit 26 of terminal 10. As a result, the control circuit 12 of terminal 10 acquires user input information I0, which includes the property name and total price (step S1).

[0084] Next, the control circuit 12 of terminal 10 transmits user input information I0 to the management server 110 via the network interface 16 (step S2). Accordingly, the network interface 116 of the management server 110 receives the user input information I0 and outputs it to the control circuit 112. As a result, the control circuit 112 of the management server 110 acquires the user input information I0 (step S101).

[0085] Next, the control circuit 112 of the management server 110 searches for real estate information I1 based on the user input information I0 (step S102). More specifically, the control circuit 112 of the management server 110 retrieves real estate information I1 containing a property name that matches the property name included in the user input information I0 from the real estate information table shown in Figure 5. In this way, the control circuit 112 of the management server 110 obtains real estate information I1 (first base information).

[0086] Next, the control circuit 112 of the management server 110 generates correspondence information I25 (step S103) and digital document generation information I21 (step S104) based on the real estate information I1 acquired in step S102. The generation of digital document generation information I21 and correspondence information I25 will be explained below with reference to Figure 19.

[0087] The memory circuit 114 of the management server 110 stores the correspondence table shown in Figure 19. The upper part of Figure 19 is the correspondence table in the initial state. The lower part of Figure 19 is the correspondence table after the generation of multiple correspondence information I25 has been completed. The correspondence table contains multiple correspondence information I25. Correspondence information I25 (first correspondence information, second correspondence information) shows the correspondence between digital document generation information I21 (first digital document generation information, second digital document generation information) and base information I22 (first base information, second base information) used to generate digital document generation information I21 (first digital document generation information, second digital document generation information). In this embodiment, correspondence information I25 shows the correspondence between digital document generation information I21, base information I22 used to generate digital document generation information I21, and acquired information I23 including base information I22.

[0088] One or more digital document generation information I21 (first digital document generation information and second digital document generation information) is information used to generate data for a property summary. The data for the property summary is an example of the first digital document D1 related to a real estate transaction. One or more digital document generation information I21 (first digital document generation information) contains information related to real estate. One or more digital document generation information I21 (first digital document generation information) contains a first category and content. The first category indicates the category to which the digital document generation information I21 belongs. The first category corresponds to, for example, the title corresponding to the box provided in the input unit 810 shown in Figure 18. The title is, for example, the address. The content is, for example, the information written in the box provided in the input unit 810 shown in Figure 18. The content is, for example, "Tokyo, XX Ward, ▲▲ 3-chome".

[0089] The acquired information I23 shown in Figure 19 is one of the following: real estate information I1, certified copy information I2, road register information I3, map information I4, land value information I5, and urban planning information I6. Furthermore, acquired information I23 includes one or more base information I22. Base information I22 is information used to generate digital document generation information I21. Base information I22 includes a second category, content, and location. The second category indicates the category to which base information I22 belongs. The second category corresponds, for example, to the title listed in the acquired information I23 displayed on the information display unit 820 shown in Figure 18. The title is, for example, land area. The content is, for example, information corresponding to the title listed in the acquired information I23 displayed on the information display unit 820 shown in Figure 18. The content is, for example, "39.53m 2 The position indicates the location of base information I22 in the certified copy information I2. The position is, for example, the X and Y coordinates of base information I22 displayed on the information display unit 820 shown in Figure 18.

[0090] In step S103, the control circuit 112 of the management server 110 identifies the second category corresponding to the first category included in the correspondence table shown in Figure 19 from the real estate information I1. In this embodiment, the control circuit 112 of the management server 110 identifies the address, total price, and lot number as the second category from the real estate information I1. The control circuit 112 of the management server 110 inputs the identified second category into the correspondence table shown in Figure 19. As a result, the control circuit 112 of the management server 110 generates three correspondence information I25. Thus, in step S103, the control circuit 112 of the management server 110 (control circuit of one or more computers, first correspondence information generation means 112d) generates correspondence information I25 (first correspondence information) that shows the correspondence between one or more digital document generation information I21 (first digital document generation information) and one or more base information I22 (first base information).

[0091] In step S104, the control circuit 112 (control circuit of one or more computers) of the management server 110 identifies one or more base information I22 (first base information) from the real estate information I1 (acquired information I23) based on the first category. More specifically, the control circuit 112 of the management server 110 identifies the content of the second category corresponding to the first category of the digital document generation information I21 as the content of the base information I22 from the real estate information I1 (acquired information I23) based on the correspondence relationship table in Figure 19. For example, if the first category of the digital document generation information I21 is an address, the control circuit 112 of the management server 110 identifies "Tokyo, XX Ward, ▲▲ 3-chome" of the address in the real estate information I1 as the content of the base information I22. Then, the control circuit 112 (control circuit of one or more computers) of the management server 110 generates digital document generation information I21 (one or more first digital document generation information) based on the base information I22 (one or more first base information) identified from the acquired information I23. Specifically, the control circuit 112 of the management server 110 sets the address content of the digital document generation information I21 to "Tokyo, XX Ward, ▲▲ 3-chome".

[0092] In step S104, the control circuit 112 of the management server 110 also generates information I21 for generating digital documents of the land parcel number and price.

[0093] Next, the control circuit 112 of the management server 110 generates the certified copy information request information I31 (step S105). The certified copy information request information I31 is information requesting the certified copy information I2 from the certified copy server 210. The certified copy information request information I31 includes the contents of the land number of the digital document generation information I21 generated in step S104. The contents of the land number are "Tokyo, XX Ward, ▲▲ 3-chome 14, 15". Then, the control circuit 112 of the management server 110 transmits the certified copy information request information I31 to the certified copy server 210 via the network interface 116 (step S106). Accordingly, the network interface 216 of the certified copy server 210 receives the certified copy information request information I31 and outputs the certified copy information request information I31 to the control circuit 212. As a result, the control circuit 212 of the certified copy server 210 obtains the certified copy information request information I31.

[0094] The control circuit 212 of the certified copy server 210 obtains certified copy information I2 corresponding to the land parcel number included in the certified copy information request information I31 from the certified copy DB 214a. The control circuit 212 of the certified copy server 210 transmits the certified copy information I2 to the management server 110 via the network interface 216. Accordingly, the network interface 116 of the management server 110 receives the certified copy information I2 and outputs the certified copy information I2 to the control circuit 112. As a result, the control circuit 112 of the management server 110 (control circuit of one or more computers, first base information acquisition means 112b) obtains certified copy information I2 (acquired information I23) including one or more base information I22 (first base information) (step S107). In other words, the control circuit 112 (control circuit of one or more computers, first base information acquisition means 112b) of the management server 110 acquires one or more base information I22 (first base information) from the certified copy server 210 (first server).

[0095] Next, the control circuit 112 of the management server 110 generates correspondence information I25 (step S108) and digital document generation information I21 (step S109) based on the certified copy information I2 acquired in step S107. The generation of digital document generation information I21 and correspondence information I25 will be explained below with reference to Figure 19.

[0096] In step S108, the control circuit 112 of the management server 110 converts the certified copy information I2 into text information using OCR (Optical Character Recognition). The control circuit 112 of the management server 110 identifies the second category corresponding to the first category included in the correspondence table shown in Figure 19 from the certified copy information I2. In this embodiment, the control circuit 112 of the management server 110 identifies the rights (Part A), rights (Part B), land category, and land area as the second category from the certified copy information I2. The control circuit 112 of the management server 110 inputs the identified second category into the correspondence table shown in Figure 19. Furthermore, the control circuit 112 of the management server 110 identifies the location of the second category in the certified copy information I2. In this embodiment, the control circuit 112 of the management server 110 identifies the location of the rights (Part A), rights (Part B), land category, and land area in the certified copy information I2. The control circuit 112 of the management server 110 inputs the identified location into the correspondence table shown in Figure 19. As a result, the control circuit 112 of the management server 110 generates four correspondence information I25. In this way, the control circuit 112 of the management server 110 (control circuit of one or more computers, first correspondence information generation means 112d) generates correspondence information I25 (first correspondence information) that shows the correspondence between one or more digital document generation information I21 (first digital document generation information) and one or more base information I22 (first base information).

[0097] In step S109, the control circuit 112 of the management server 110 (control circuit of one or more computers, first base information identification means 112e) identifies one or more base information I22 (first base information) from the acquired information I23 based on the first category. Based on the correspondence relationship table in Figure 19, the control circuit 112 of the management server 110 identifies the content of the second category corresponding to the first category of the digital document generation information I21 as the content of the base information I22 from the certified copy information I2 (acquired information I23). For example, if the first category of the digital document generation information I21 is land area, the control circuit 112 of the management server 110 identifies the land area of ​​"39.53m" in the certified copy information I2. 2 The control circuit 112 of the management server 110 identifies "39.53m" as the content of the base information I22. Then, based on the base information I22 (one or more first base information) identified from the acquired information I23, the control circuit 112 of the management server 110 generates digital document generation information I21 (one or more first digital document generation information). Specifically, the control circuit 112 of the management server 110 identifies "39.53m" as the content of the land area in the digital document generation information I21. 2 Set "".

[0098] Next, the control circuit 112 of the management server 110 generates road register information request information I32 (step S110). The road register information request information I32 is information requesting road register information I3 from the road register server 310. The road register information request information I32 includes the address content of the digital document generation information I21 generated in step S104. Then, the control circuit 112 of the management server 110 transmits the road register information request information I32 to the road register server 310 via the network interface 116 (step S111). Accordingly, the network interface 316 of the road register server 310 receives the road register information request information I32 and outputs the road register information request information I32 to the control circuit 312. As a result, the control circuit 312 of the road register server 310 acquires the road register information request information I32.

[0099] The control circuit 312 of the road ledger server 310 obtains road ledger information I3 corresponding to the address included in the road ledger information request information I32 from the road ledger DB 314a. The control circuit 312 of the road ledger server 310 transmits the road ledger information I3 to the management server 110 via the network interface 316. Accordingly, the network interface 116 of the management server 110 receives the road ledger information I3 and outputs the road ledger information I3 to the control circuit 112. As a result, the control circuit 112 of the management server 110 (control circuit of one or more computers, second base information acquisition means 112i) obtains road ledger information I3 (acquired information I23) including one or more base information I22 (second base information) (step S112). In other words, the control circuit 112 (control circuit of one or more computers, second base information acquisition means 112i) of the management server 110 acquires one or more base information I22 (second base information) from the road ledger server 310 (second server).

[0100] Next, the control circuit 112 of the management server 110 generates correspondence relationship information I25 (step S113) and digital document generation information I21 (step S114) based on the road register information I3 acquired in step S112. The generation of digital document generation information I21 and correspondence relationship information I25 will be explained below with reference to Figure 19.

[0101] In step S113, the control circuit 112 of the management server 110 converts the road register information I3 into text information using OCR. The control circuit 112 of the management server 110 identifies the second category corresponding to the first category included in the correspondence table shown in Figure 19 from the road register information I3. In this embodiment, the control circuit 112 of the management server 110 identifies private road area and private road burden as the second category from the road register information I3. The control circuit 112 of the management server 110 inputs the identified second category into the correspondence table shown in Figure 19. Furthermore, the control circuit 112 of the management server 110 identifies the location of the second category in the road register information I3. In this embodiment, the control circuit 112 of the management server 110 identifies the location of private road area and private road burden in the road register information I3. The control circuit 112 of the management server 110 inputs the identified location into the correspondence table shown in Figure 19. As a result, the control circuit 112 of the management server 110 generates two correspondence relationship information I25. In this way, the control circuit 112 of the management server 110 (control circuit of one or more computers, first correspondence relationship information generation means 112d) generates correspondence relationship information I25 (second correspondence relationship information) that shows the correspondence between one or more digital document generation information I21 (second digital document generation information) and one or more base information I22 (second base information).

[0102] In step S114, the control circuit 112 (control circuit of one or more computers) of the management server 110 identifies one or more base information I22 (second base information) from the acquired information I23 based on the first category. Based on the correspondence relationship table in Figure 19, the control circuit 112 of the management server 110 identifies the content of the second category corresponding to the first category of the digital document generation information I21 as the content of the base information I22 from the road register information I3 (acquired information I23). For example, if the first category of the digital document generation information I21 is private road burden, the control circuit 112 of the management server 110 identifies "none" for private road burden in the road register information I3 as the content of the base information I22. Then, the control circuit 112 (control circuit of one or more computers) of the management server 110 generates one or more digital document generation information I21 (second digital document generation information) based on the one or more base information I22 (second base information) identified from the acquired information I23. Specifically, the control circuit 112 of the management server 110 sets the content of the land area in the digital document generation information I21 to "none".

[0103] In step S114, the control circuit 112 of the management server 110 also generates information I21 for generating a digital document of the private road area.

[0104] Next, the control circuit 112 of the management server 110 generates map information request information I33 (step S115). Map information request information I33 is information requesting map information I4 from the map server 410. Map information request information I33 includes the address content of the digital document generation information I21 generated in step S104. Then, the control circuit 112 of the management server 110 transmits the map information request information I33 to the map server 410 via the network interface 116 (step S116). Accordingly, the network interface 416 of the map server 410 receives the map information request information I33 and outputs the map information request information I33 to the control circuit 412. As a result, the control circuit 412 of the map server 410 acquires the map information request information I33.

[0105] The control circuit 412 of the map server 410 obtains map information I4 corresponding to the address included in the map information request information I33 from the map DB 414a. Furthermore, the control circuit 412 of the map server 410 searches for the nearest station based on the address included in the map information request information I33. The control circuit 412 of the map server 410 sets the address included in the map information request information I33 as the starting point and the nearest station as the destination. Then, the control circuit 412 of the map server 410 calculates the route from the starting point to the destination. The control circuit 412 of the map server 410 sets the route from the starting point to the destination, the distance from the starting point to the destination, and the walking time from the starting point to the destination in the map information I4. The control circuit 412 of the map server 410 transmits the map information I4 to the management server 110 via the network interface 416. Accordingly, the network interface 116 of the management server 110 receives the map information I4 and outputs the map information I4 to the control circuit 112. As a result, the control circuit 112 of the management server 110 (control circuit of one or more computers, second base information acquisition means 112i) acquires map information I4 (acquired information I23) which includes one or more base information I22 (second base information) (step S117). That is, the control circuit 112 of the management server 110 (control circuit of one or more computers, second base information acquisition means 112i) acquires one or more base information I22 (second base information) from the map server 410 (second server).

[0106] Next, the control circuit 112 of the management server 110 generates correspondence information I25 (step S118) and digital document generation information I21 (step S119) based on the map information I4 acquired in step S117. The generation of digital document generation information I21 and correspondence information I25 will be explained below with reference to Figure 19.

[0107] In step S118, the control circuit 112 of the management server 110 converts the map information I4 into text information using OCR. The control circuit 112 of the management server 110 identifies the second category corresponding to the first category included in the correspondence table shown in Figure 19 from the map information I4. In this embodiment, the control circuit 112 of the management server 110 identifies the destination and travel time as the second category from the road register information I3. The control circuit 112 of the management server 110 inputs the identified second category into the correspondence table shown in Figure 19. Furthermore, the control circuit 112 of the management server 110 identifies the location of the second category in the map information I4. In this embodiment, the control circuit 112 of the management server 110 identifies the location of the destination and travel time in the map information I4. The control circuit 112 of the management server 110 inputs the identified location into the correspondence table shown in Figure 19. As a result, the control circuit 112 of the management server 110 generates correspondence information I25. In this manner, the control circuit 112 (control circuit of one or more computers, first correspondence relationship information generation means 112d) of the management server 110 generates correspondence relationship information I25 (second correspondence relationship information) that shows the correspondence between one or more digital document generation information I21 (second digital document generation information) and one or more base information I22 (second base information).

[0108] In step S119, the control circuit 112 (control circuit of one or more computers) of the management server 110 identifies one or more base information I22 (second base information) from the acquired information I23 based on the first category. Based on the correspondence table in Figure 19, the control circuit 112 of the management server 110 identifies the content of the second category corresponding to the first category of the digital document generation information I21 as the content of the base information I22 from the map information I4 (acquired information I23). For example, if the first category of the digital document generation information I21 is the nearest station, the control circuit 112 of the management server 110 identifies "Station A" of the destination in the map information I4 as the content of the base information I22. Then, the control circuit 112 (control circuit of one or more computers) of the management server 110 generates one or more digital document generation information I21 (second digital document generation information) based on the one or more base information I22 (second base information) identified from the acquired information I23. Specifically, the control circuit 112 of the management server 110 sets the content of the nearest station in the digital document generation information I21 to "Station A".

[0109] In step S119, the control circuit 112 of the management server 110 also generates information I21 for generating a digital document for a given time.

[0110] Next, the control circuit 112 of the management server 110 generates land value information request information I34 (step S120). The land value information request information I34 is information requesting land value information I5 from the land value server 510. The land value information request information I34 includes the address content of the digital document generation information I21 generated in step S104. Then, the control circuit 112 of the management server 110 transmits the land value information request information I34 to the urban planning server 610 via the network interface 116 (step S121). Accordingly, the network interface 516 of the land price server 510 receives the land price information request information I34 and outputs the land price information request information I34 to the control circuit 512. As a result, the control circuit 512 of the land price server 510 acquires the land price information request information I34.

[0111] The control circuit 512 of the land value server 510 obtains land value information I5 corresponding to the address included in the land value information request information I34 from the land value DB 514a. The control circuit 512 of the land value server 510 transmits the land value information I5 to the management server 110 via the network interface 516. Accordingly, the network interface 116 of the management server 110 receives the land value information I5 and outputs the land value information I5 to the control circuit 112. As a result, the control circuit 112 of the management server 110 (control circuit of one or more computers, second base information acquisition means 112i) acquires land price information I5 (acquired information I23) which includes one or more base information I22 (second base information) (step S122). That is, the control circuit 112 of the management server 110 (control circuit of one or more computers, second base information acquisition means 112i) acquires one or more base information I22 (second base information) from the land price server 510 (second server).

[0112] Next, the control circuit 112 of the management server 110 generates correspondence relationship information I25 (step S123) and digital document generation information I21 (step S124) based on the land value information I5 acquired in step S122. The generation of digital document generation information I21 and correspondence relationship information I25 will be explained below with reference to Figure 19.

[0113] In step S123, the control circuit 112 of the management server 110 converts the land value information I5 into text information using OCR. The control circuit 112 of the management server 110 identifies the second category corresponding to the first category included in the correspondence table shown in Figure 19 from the land value information I5. In this embodiment, the control circuit 112 of the management server 110 identifies the land value as the second category from the land value information I5. The control circuit 112 of the management server 110 inputs the identified second category into the correspondence table shown in Figure 19. Furthermore, the control circuit 112 of the management server 110 identifies the position of the second category in the land value information I5. In this embodiment, the control circuit 112 of the management server 110 identifies the position of the land value in the land value information I5. The control circuit 112 of the management server 110 inputs the identified position into the correspondence table shown in Figure 19. As a result, the control circuit 112 of the management server 110 generates the correspondence information I25. In this manner, the control circuit 112 (control circuit of one or more computers, first correspondence relationship information generation means 112d) of the management server 110 generates correspondence relationship information I25 (second correspondence relationship information) that shows the correspondence between one or more digital document generation information I21 (second digital document generation information) and one or more base information I22 (second base information).

[0114] In step S124, the control circuit 112 (control circuit of one or more computers) of the management server 110 identifies one or more base information I22 (second base information) from the acquired information I23 based on the first category. Based on the correspondence table in Figure 19, the control circuit 112 of the management server 110 identifies the content of the second category corresponding to the first category of the digital document generation information I21 as the content of base information I22 from the land value information I5 (acquired information I23). For example, if the first category of the digital document generation information I21 is land value, the control circuit 112 of the management server 110 identifies "300,000" of the land value information I5 as the content of base information I22. Then, the control circuit 112 (control circuit of one or more computers) of the management server 110 generates one or more digital document generation information I21 (second digital document generation information) based on the one or more identified base information I22 (second base information) from the acquired information I23. Specifically, the control circuit 112 of the management server 110 sets the land value content of the digital document generation information I21 to "300,000".

[0115] Next, the control circuit 112 of the management server 110 generates urban planning information request information I35 (step S125). Urban planning information request information I35 is information requesting urban planning information I6 from the urban planning server 610. Urban planning information request information I35 includes the address content of the digital document generation information I21 generated in step S104. Then, the control circuit 112 of the management server 110 transmits the urban planning information request information I35 to the urban planning server 610 via the network interface 116 (step S126). Accordingly, the network interface 616 of the urban planning server 610 receives the urban planning information request information I35 and outputs the urban planning information request information I35 to the control circuit 612. As a result, the control circuit 612 of the urban planning server 610 acquires the urban planning information request information I35.

[0116] The control circuit 612 of the urban planning server 610 obtains urban planning information I6 corresponding to the address included in the urban planning information request information I35 from the urban planning DB 614a. The control circuit 612 of the urban planning server 610 transmits the urban planning information I6 to the management server 110 via the network interface 616. Accordingly, the network interface 116 of the management server 110 receives the urban planning information I6 and outputs the urban planning information I6 to the control circuit 112. As a result, the control circuit 112 of the management server 110 (control circuit of one or more computers, second base information acquisition means 112i) obtains urban planning information I6 (acquired information I23) including one or more base information I22 (second base information) (step S127). That is, the control circuit 112 of the management server 110 (control circuit of one or more computers, second base information acquisition means 112i) obtains one or more base information I22 (second base information) from the urban planning server 610 (second server).

[0117] Next, the control circuit 112 of the management server 110 generates correspondence relationship information I25 (step S128) and digital document generation information I21 (step S129) based on the urban planning information I6 acquired in step S127. The generation of digital document generation information I21 and correspondence relationship information I25 will be explained below with reference to Figure 19.

[0118] In step S128, the control circuit 112 of the management server 110 converts the urban planning information I6 into text information using OCR. The control circuit 112 of the management server 110 identifies the second category corresponding to the first category included in the correspondence table shown in Figure 19 from the urban planning information I6. In this embodiment, the control circuit 112 of the management server 110 identifies the urbanization classification, land use zone, building coverage ratio, and floor area ratio as the second category from the road register information I3. The control circuit 112 of the management server 110 inputs the identified second category into the correspondence table shown in Figure 19. Furthermore, the control circuit 112 of the management server 110 identifies the location of the second category in the urban planning information I6. In this embodiment, the control circuit 112 of the management server 110 identifies the location of the urbanization classification, land use zone, building coverage ratio, and floor area ratio in the urban planning information I6. The control circuit 112 of the management server 110 inputs the identified location into the correspondence table shown in Figure 19. As a result, the control circuit 112 of the management server 110 generates four correspondence relationship information I25. In this way, the control circuit 112 of the management server 110 (control circuit of one or more computers, second correspondence relationship information generation means 112k) generates correspondence relationship information I25 (second correspondence relationship information) that shows the correspondence between one or more digital document generation information I21 (second digital document generation information) and one or more base information I22 (second base information).

[0119] In step S129, the control circuit 112 (control circuit of one or more computers) of the management server 110 identifies one or more base information I22 (second base information) from the acquired information I23 based on the first category. Based on the correspondence relationship table in Figure 19, the control circuit 112 of the management server 110 identifies the content of the second category corresponding to the first category of the digital document generation information I21 as the content of base information I22 from the urban planning information I6 (acquired information I23). For example, if the first category of the digital document generation information I21 is urbanization classification, the control circuit 112 of the management server 110 identifies "urbanization area" of the urbanization classification in urban planning information I6 as the content of base information I22. Then, the control circuit 112 of the management server 110 (control circuit of one or more computers, second digital document generation information generation means 112j) generates one or more digital document generation information I21 (second digital document generation information) based on one or more base information I22 (second base information) identified from the acquired information I23. Specifically, the control circuit 112 of the management server 110 sets "urbanization area" to the content of the urbanization classification in the digital document generation information I21.

[0120] In step S119, the control circuit 112 of the management server 110 also generates information I21 for generating digital documents of the land use zone, building coverage ratio, and floor area ratio.

[0121] Next, the control circuit 112 of the management server 110 generates photo information request information I36 (step S130). Photo information request information I36 is information requesting photo information I7 from the photo server 710. Photo information request information I36 includes the address content of the digital document generation information I21 generated in step S104. Then, the control circuit 112 of the management server 110 transmits the photo information request information I36 to the photo server 710 via the network interface 116 (step S131). Accordingly, the network interface 716 of the photo server 710 receives the photo information request information I36 and outputs the photo information request information I36 to the control circuit 712. As a result, the control circuit 712 of the photo server 710 acquires the photo information request information I36.

[0122] The control circuit 712 of the photo server 710 obtains photo information I7 corresponding to the address included in the photo information request information I36 from the photo database 714a. The control circuit 712 of the photo server 710 transmits the photo information I7 to the management server 110 via the network interface 716. Accordingly, the network interface 116 of the management server 110 receives the photo information I7 and outputs the photo information I7 to the control circuit 112. As a result, the control circuit 112 of the management server 110 (control circuit of one or more computers / photo information acquisition means 112p) obtains the photo information I7 from the photo server 710 (fifth server) (step S132).

[0123] Next, the control circuit 112 of the management server 110 (control circuit of one or more computers, first display information generation means 112a, second display information generation means 112h) generates display information I53 (first display information, second display information) for displaying digital document generation information I21 (one or more first digital document generation information, one or more second digital document generation information) and base information I22 (one or more first base information, one or more second base information) used to generate digital document generation information I21 (one or more first digital document generation information, one or more second digital document generation information) on the display (step S133). The display information I53 is information for displaying the input image 800 shown in Figure 18 on the display 20 of the terminal 10. The display information I53 includes the multiple digital document generation information I21 generated in steps S114, S119, S124, and S129.

[0124] Furthermore, in step S133, the control circuit 112 of the management server 110 (control circuit of one or more computers, first display information generation means 112a, second display information generation means 112h) generates display information I53 (first display information, second display information) so as to include a plurality of correspondence information I25 (first correspondence information, second correspondence information). More specifically, the display information I53 includes the plurality of correspondence information I25 (first correspondence information, second correspondence information) generated in steps S115, S120, S125, and S130. Correspondence information I25 is information for displaying correspondence indicators 850, 860 (first correspondence indicator, second correspondence indicator; see Figure 18) on the display 20, which show the correspondence between one or more digital document generation information I21 (first digital document generation information, second digital document generation information) and one or more base information I22 (first base information, second base information) used to generate the one or more digital document generation information I21 (first digital document generation information, second digital document generation information). Correspondence indicators 850, 860 will be described later.

[0125] Next, the control circuit 112 of the management server 110 transmits the display information I53 generated in step S133 to the terminal 10 via the network interface 116 (step S134). Accordingly, the network interface 16 of the terminal 10 outputs the display information I53 to the control circuit 12. As a result, the control circuit 12 of the terminal 10 acquires the display information I53 and a plurality of correspondence information I25 (step S3).

[0126] Next, the control circuit 12 of terminal 10 displays the input image 800 shown in Figure 18 on the display 20 based on the display information I53 (step S4). Specifically, the control circuit 12 of terminal 10 inputs the contents of the multiple digital document generation information I21 included in the display information I53 into the box included in the input unit 810. As a result, the control circuit 12 of terminal 10 displays the multiple digital document generation information I21 on the display 20. Furthermore, the control circuit 12 of terminal 10 inputs the copy information I2 into the information display unit 820. As a result, the control circuit 12 of terminal 10 displays the base information I22 used to generate the digital document generation information I21 on the display 20.

[0127] Furthermore, the control circuit 12 of terminal 10 displays correspondence displays 850 and 860 on the display 20 based on the multiple correspondence information I25 contained in the display information I53. More specifically, the correspondence indicators 850 and 860 (first correspondence indicators) are highlighting applied to one or more digital document generation information I21 (first digital document generation information) and one or more base information I22 (first base information). The correspondence indicators 850 and 860 are displays that allow the user to visually perceive the relationship between the digital document generation information I21 and the base information I22. In this embodiment, the control circuit 12 of the terminal 10 displays the correspondence indicator 850 by highlighting the land area box included in the input unit 810. Furthermore, the control circuit 12 of the terminal 10 identifies the second category corresponding to the first category of land area as land area based on the correspondence information I25. Then, the control circuit 12 of the terminal 10 displays the correspondence indicator 860 by highlighting the land area included in the information display unit 820 based on the location of the land area included in the correspondence information I25. Highlighting, for example, means coloring the text and the area surrounding it.

[0128] Furthermore, the control circuit 12 of terminal 10 may highlight the boxes for land rights, co-ownership, and land category. However, in Figure 18, the control circuit 112 of management server 110 has not been able to obtain the contents of the rights section (Section A), rights section (Section B), and land category from the certified copy information I2. Therefore, the contents of the digital document generation information I21 are not entered into the boxes for land rights, co-ownership, and land category. This terminates the process.

[0129] (2)Second operation Next, the details of the second operation of System 1 will be explained with reference to the diagrams. Figure 24 is a flowchart of the second operation performed by the control circuit 12 of terminal 10. Figure 25 is a diagram showing the image displayed on display 20.

[0130] First, the control circuit 12 of terminal 10 displays the input image 800 shown in Figure 18 based on the display information I53 (step S11).

[0131] Next, the user selects a box included in the input unit 810 by operating the operation unit 26 of the terminal 10. In this embodiment, the user clicks the box for the nearest station. As a result, the control circuit 12 of the terminal 10 obtains user selection information I38 (step S12). User selection information I38 is information for identifying the box selected by the user. Therefore, user selection information I38 includes a first category of digital document generation information I21 corresponding to the box selected by the user. In this embodiment, user selection information I38 includes the nearest station as the first category.

[0132] Next, the control circuit 12 of terminal 10 identifies acquired information I23 that includes a second category corresponding to the first category included in user selection information I38, based on the correspondence table (multiple correspondence information I25) shown in Figure 19 (step S13). If the first category is the nearest station, the control circuit 12 of terminal 10 identifies acquired information I23 as map information I4.

[0133] Next, as shown in Figure 25, the control circuit 12 of the terminal 10 inputs the map information I4 contained in the display information I53 to the information display unit 820. As a result, the control circuit 12 of the terminal 10 displays the map information I4 (acquired information I23) on the display 20 (step S14).

[0134] Furthermore, the control circuit 12 of terminal 10 displays correspondence displays 850 and 860 on the display 20 based on the correspondence information I25 contained in the display information I53 (step S15). In this embodiment, the control circuit 12 of terminal 10 displays correspondence display 850 by highlighting the nearest station box contained in the input unit 810. Furthermore, the control circuit 12 of terminal 10 displays correspondence display 860 by highlighting the destination contained in the information display unit 820. This completes the process.

[0135] (3) Third action Next, we will explain the details of the third operation of System 1 with reference to the diagram. Figure 26 is a flowchart of the third operation performed by the control circuit 12 of terminal 10 and the control circuit 112 of management server 110.

[0136] First, the user operates the control unit 26 of the terminal 10 to instruct the management server 110 to generate the first digital document D1. In response, the control circuit 12 of the terminal 10 generates the first digital document request information I37 (step S21).

[0137] Next, the control circuit 12 of terminal 10 transmits the first digital document request information I37 to the management server 110 via the network interface 16 (step S22). Accordingly, the network interface 116 of the management server 110 receives the first digital document request information I37 and outputs the first digital document request information I37 to the control circuit 112. As a result, the control circuit 112 of the management server 110 acquires the first digital document request information I37 (step S151).

[0138] Next, the control circuit 112 (control circuit of one or more computers / first digital document generation means 112n) of the management server 110 generates a first digital document D1 based on one or more digital document generation information I21 (first digital document generation information) generated in steps S114, S119, S124, and S129 (step S152). The first digital document D1 is data of a property description (see Figure 17) of real estate to be rented or sold. The first digital document D1 may be, for example, PDF data or WORD data.

[0139] Next, the control circuit 112 of the management server 110 transmits the first digital document D1 to the terminal 10 via the network interface 116 (step S153). Accordingly, the network interface 16 of terminal 10 receives the first digital document D1 and outputs the first digital document D1 to the control circuit 12. As a result, the control circuit 12 of terminal 10 acquires the first digital document D1 (step S23).

[0140] Finally, the control circuit 12 of terminal 10 displays the first digital document D1 shown in Figure 17 on the display 20 (step S24). This completes the process.

[0141] [effect] According to System 1, the user can easily verify whether the contents of the first digital document D1 relating to real estate are correct. More specifically, the control circuit 112 of the management server 110 generates display information I53. This allows the control circuit 12 of the terminal 10 to display the digital document generation information I21 and the base information I22 used to generate the digital document generation information I21 on the display 20. The display information I53 includes multiple correspondence information I25. The correspondence information I25 is information for displaying correspondence displays 850,860 on the display 20, which show the correspondence between the digital document generation information I21 and the base information I22 used to generate the digital document generation information I21. This allows the user to recognize the correspondence between the digital document generation information I21 and the base information I22 used to generate the digital document generation information I21. Therefore, according to System 1, the user can easily verify whether the contents of the first digital document D1 relating to real estate are correct.

[0142] According to System 1, the control circuit 112 of the management server 110 can easily generate digital document generation information I21. More specifically, each of the one or more digital document generation information I21 includes a first category to which the one or more digital document generation information I21 belong. Based on the first category, the control circuit 112 of the management server 110 identifies one or more base information I22 from the acquired information I23. Therefore, the control circuit 112 of the management server 110 can easily identify the base information I22 used to generate the digital document generation information I21. Thus, according to System 1, the control circuit 112 of the management server 110 can easily generate digital document generation information I21.

[0143] In System 1, the control circuit 112 of the management server 110 obtains one or more base information I22 from the certified copy server 210. In this way, the control circuit 112 of the management server 110 can generate one or more digital document generation information I21 using one or more base information I22 obtained from a server located outside the management server 110. Furthermore, in this embodiment, the base information I22 is information issued by a public institution. Therefore, the control circuit 112 of the management server 110 can generate one or more digital document generation information I21 based on one or more base information I22 issued by a public institution. As a result, the probability of errors occurring in the first digital document D1 is reduced.

[0144] In System 1, the control circuit 112 of the management server 110 acquires urban planning information I6 (acquired information I23) which includes one or more base information I22. In this way, the control circuit 112 of the management server 110 can generate one or more digital document generation information I21 using one or more base information I22 acquired from multiple servers located outside the management server 110.

[0145] In System 1, the correspondence indicators 850 and 860 are highlighting applied to one or more digital document generation information I21 and one or more base information I22. This allows the user to visually confirm the correspondence between the digital document generation information I21 and the base information I22 used to generate the digital document generation information I21.

[0146] (First variation) Next, the system 1a relating to the first modified example will be described with reference to the drawings. Figure 27 is a flowchart of the first operation performed by the control circuit 12 of the terminal 10 and the control circuit 112 of the management server 110. Figure 28 is a diagram showing the correspondence table.

[0147] System 1a differs from System 1 in that the control circuit 112 of the management server 110 generates the first digital document D1 based on the second digital document D2. The second digital document D2 is related to a real estate transaction and is acquired information I23. The second digital document D2 is data from a property summary. However, the creator of the second digital document D2 (real estate agent) is different from the creator of the first digital document D1 (real estate agent). Therefore, the format of the second digital document D2 is different from the format of the first digital document D1.

[0148] First, the user inputs the second digital document D2 by operating the operation unit 26 of the terminal 10. The user may download the second digital document D2 to the terminal 10 from a server (not shown), or input the second digital document D2 by scanning a property summary document. As a result, the operation unit 26 of the terminal 10 acquires the second digital document D2 (step S31). The second digital document D2 contains one or more base information I22 (first base information). Each of the one or more base information I22 (first base information) contains a second category and content. The second category, like the first category, indicates the category to which the one or more base information I22 (first base information) belongs. The second category is, for example, an address. The content is the content of the base information I22. The content is, for example, "3-chome, ▲▲, ○○-ku, Tokyo".

[0149] Next, the control circuit 12 of terminal 10 transmits the second digital document D2 to the management server 110 via the network interface 16 (step S32). Accordingly, the network interface 116 of the management server 110 receives the second digital document D2 and outputs the second digital document D2 to the control circuit 112. As a result, the control circuit 112 (control circuit of one or more computers) of the management server 110 acquires the second digital document D2 (step S201).

[0150] Next, the control circuit 112 of the management server 110 generates correspondence information I25 based on the second digital document D2 acquired in step S201 (step S202), and also generates digital document generation information I21 (step S203). The generation of digital document generation information I21 and correspondence relationship information I25 will be explained below with reference to Figure 28.

[0151] In step S202, the control circuit 112 of the management server 110 converts the second digital document D2 into text information using OCR. The control circuit 112 of the management server 110 identifies the second categories from the second digital document D2 that correspond to the first categories included in the correspondence table shown in Figure 28. In this embodiment, the control circuit 112 of the management server 110 identifies 17 second categories from the second digital document D2, ranging from the address to the land value. The control circuit 112 of the management server 110 inputs the identified second categories into the correspondence table shown in Figure 19. Furthermore, the control circuit 112 of the management server 110 identifies the location of the second category in the second digital document D2. In this embodiment, the control circuit 112 of the management server 110 identifies the location of 17 second categories from the address to the land value in the second digital document D2. The control circuit 112 of the management server 110 inputs the identified locations into the correspondence table shown in Figure 19. As a result, the control circuit 112 of the management server 110 generates 17 correspondence information pieces I25.

[0152] In step S203, the control circuit 112 (control circuit of one or more computers) of the management server 110 identifies one or more base information I22 (first base information) from the second digital document D2 based on the first category and the second category. Based on the correspondence relationship table in Figure 28, the control circuit 112 of the management server 110 identifies the content of the second category corresponding to the first category of the digital document generation information I21 as the content of the base information I22 from the second digital document D2 (acquired information I23). For example, if the first category of the digital document generation information I21 is an address, the control circuit 112 of the management server 110 identifies "Tokyo, XX Ward, ▲▲ 3-chome" of the address in the second digital document D2 as the content of the base information I22. Then, the control circuit 112 of the management server 110 (control circuit of one or more computers, first digital document generation information generation means 112c) generates one or more digital document generation information I21 (first digital document generation information) based on one or more base information I22 (first base information) identified from the acquired information I23. Specifically, the control circuit 112 of the management server 110 sets the content of the address in the digital document generation information I21 to "Tokyo, XX Ward, ▲▲ 3-chome". The control circuit 112 of the management server 110 also generates the remaining 16 digital document generation information I21. Steps S204, S205, S33, and S34 in Figure 27 are the same as steps S133, S134, S3, and S4 in Figures 20 and 23, respectively, so their explanation is omitted.

[0153] System 1a can achieve the same effect as System 1. Furthermore, System 1a can generate a first digital document D1 based on a second digital document D2 created by another real estate agent.

[0154] (Second variation) Next, we will describe system 1b, which relates to the second modified example, with reference to the drawings. Figure 29 is a flowchart of the first operation performed by the control circuit 112 of the management server 110.

[0155] System 1b differs from System 1a in that the control circuit 112 of the management server 110 determines whether the base information I22 contained in the second digital document D2 is correct. The operation of System 1b will be explained below, focusing on this difference.

[0156] Steps S201 to S203 in Figure 29 are the same as steps S201 to S203 in Figure 27, so their explanation is omitted. Also, step S102 in Figure 29 is the same as step S102 in Figure 20, so its explanation is omitted.

[0157] The control circuit 112 of the management server 110 (control circuit / determination means 112g of one or more computers) determines whether one or more base information I22 (first base information) contained in the second digital document D2 is accurate based on the real estate information I1 (first determination information) (step S210). More specifically, the base information I22 in step S210 is an address. Therefore, the control circuit 112 of the management server 110 determines whether the address contained in the base information I22 matches the address contained in the real estate information I1. If the address contained in the base information I22 matches the address contained in the real estate information I1, the base information I22 (first base information) contained in the second digital document D2 is accurate. In this case, the process proceeds to step S211. If the address contained in the base information I22 does not match the address contained in the real estate information I1, the base information I22 (first base information) contained in the second digital document D2 is inaccurate. In this case, the process proceeds to step S212.

[0158] If the base information I22 (first base information) contained in the second digital document D2 is accurate, the control circuit 112 of the management server 110 generates digital document generation information I21 based on the second digital document D2 (step S211). Step S211 is the same as step S104 in Figure 20, except that the second digital document D2 is used instead of the real estate information I1, so its explanation is omitted.

[0159] If the base information I22 (first base information) contained in the second digital document D2 is inaccurate, the control circuit 112 of the management server 110 generates judgment result information I55 indicating that the second digital document D2 is incorrect (step S212). Furthermore, the control circuit 112 of the management server 110 generates digital document generation information I21 based on the real estate information I1 (step S213). Note that step S213 is the same as step S104 in Figure 20, so the explanation is omitted.

[0160] Steps S105 to S107 in Figure 29 are the same as steps S105 to S107 in Figure 20, so their explanation is omitted. In step S107, the control circuit 112 (control circuit of one or more computers, first determination information acquisition means 112f) of the management server 110 acquires certified copy information I2 (first determination information) from the certified copy server 210 (fourth server) which is connected to the management server 110 (one or more computers) via a network, based on one or more base information I22 (first base information).

[0161] The control circuit 112 of the management server 110 (control circuit / determination means 112g of one or more computers) determines whether one or more base information I22 (first base information) contained in the second digital document D2 is accurate based on the certified copy information I2 (first determination information) (step S214). More specifically, the one or more base information I22 in step S214 is, for example, the rights section (Section A). The control circuit 112 of the management server 110 then determines whether the rights section (Section A) contained in the one or more base information I22 matches the land rights contained in the one or more certified copy information I2. If the rights section (Section A) contained in the one or more base information I22 matches the land rights contained in the one or more certified copy information I2, then the one or more base information I22 (first base information) contained in the second digital document D2 is accurate. In this case, the process proceeds to step S215. If the rights section (Section A) contained in one or more base information I22 does not match the land rights contained in one or more certified copy information I2, then one or more base information I22 (first base information) contained in the second digital document D2 is inaccurate. In this case, the process proceeds to step S216.

[0162] If one or more base information I22 (first base information) contained in the second digital document D2 is accurate, the control circuit 112 of the management server 110 generates digital document generation information I21 based on the second digital document D2 (step S215). Step S215 is the same as step S109 in Figure 20, except that the second digital document D2 is used instead of the copy information I2, so the explanation is omitted.

[0163] If one or more base information I22 (first base information) contained in the second digital document D2 is inaccurate, the control circuit 112 of the management server 110 generates determination result information I55 indicating that the second digital document D2 is incorrect (step S216). Furthermore, the control circuit 112 of the management server 110 generates digital document generation information I21 based on the certified copy information I2 (step S217). Note that step S213 is the same as step S109 in Figure 20, so its explanation is omitted.

[0164] After this, the control circuit 112 of the management server 110 acquires road register information I3, map information I4, land value information I5, and urban planning information I6. Then, the control circuit 112 of the management server 110 repeats the same process as in steps S214 to S217, repeatedly determining whether one or more base information I22 contained in the second digital document D2 are accurate based on the road register information I3, map information I4, land value information I5, and urban planning information I6.

[0165] Next, the control circuit 112 (one or more computers and first display information generation means 112a) of the management server 110 generates display information I53 (first display information) that allows the digital document generation information I21 and the base information I22 used to generate the digital document generation information I21 to be displayed on the display (step S204). The display information I53 (first display information) includes a determination result display that shows the result of the determination. Note that step S204 is the same as step S133, so the explanation is omitted.

[0166] Next, the control circuit 112 of the management server 110 transmits the display information I53 generated in step S204 to the terminal 10 via the network interface 116 (step S205).

[0167] System 1b can achieve the same effect as System 1a. Furthermore, with System 1b, if there is an error in one or more base information I22 contained in the second digital document D2, the user can be informed of this through the display of the judgment result.

[0168] (Third variation) Next, we will describe system 1c, which relates to the third modified example, with reference to the drawings. Figure 30 is a flowchart of the first operation performed by the control circuit 112 of the management server 110.

[0169] System 1c differs from System 1b in that the user inputs the base information I22. The operation of System 1c will be explained below, focusing on this difference.

[0170] First, the control circuit 12 of terminal 10 displays the input image 800 shown in Figure 18 on the display 20. The real estate agent (user) operates the operation unit 26 of terminal 10 to input the property name, total price, address, lot number, nearest station, and walking distance in the image shown in Figure 18. As a result, the control circuit 12 of terminal 10 acquires user input information I0 (base information), including the property name, total price, address, lot number, nearest station, and walking distance. The property name, total price, address, lot number, nearest station, and walking distance are one or more pieces of base information I22 (first base information).

[0171] Next, the control circuit 12 of terminal 10 transmits user input information I0 to the management server 110 via the network interface 16. Accordingly, the network interface 116 of the management server 110 receives the user input information I0 and outputs it to the control circuit 112. As a result, the control circuit 112 of the management server 110 (control circuit of one or more computers, first base information acquisition means 112b) acquires user input information I0 including one or more base information I22 (first base information) input by the user (step S301). Steps S202 onwards in Figure 30 are the same as steps S202 onwards in Figure 29, so the explanation is omitted.

[0172] System 1c can achieve the same effect as System 1b. Furthermore, with System 1b, if there is an error in one or more base information I22 entered by the user, the user can be notified of this through the display of the judgment result.

[0173] (Fourth variation) Next, we will describe system 1d relating to the fourth modified example with reference to the drawings. Figure 31 shows an image displayed on the display 20.

[0174] System 1d differs from System 1 in its display configuration of the land value information I5. More specifically, in step S121 of Figure 20, the control circuit 112 of the management server 110 transmits the land value information request information I34 to the urban planning server 610 via the network interface 116. Accordingly, the network interface 516 of the urban planning server 610 receives the land value information request information I34 and outputs the land value information request information I34 to the control circuit 512. As a result, the control circuit 512 of the land value server 510 acquires the land value information request information I34.

[0175] The control circuit 512 of the land value server 510 obtains nine land value information I5 corresponding to the addresses included in the land value information request information I34 from the land value DB 514a. Specifically, the control circuit 512 of the land value server 510 obtains the land value information I5 for the address included in the land value information request information I34, and eight land value information I5 adjacent to the land value information I5 for the address included in the land value information request information I34. The control circuit 512 of the land value server 510 transmits the nine land value information I5 to the management server 110 via the network interface 516. Accordingly, the network interface 116 of the management server 110 receives the nine land value information I5 and outputs the nine land value information I5 to the control circuit 112. As a result, in step S122, the control circuit 112 of the management server 110 obtains nine land value information I5 including one or more base information I22. The control circuit 112 of the management server 110 generates the combined land value information I15 shown in Figure 31 by combining nine land value information I5.

[0176] The control circuit 112 of the management server 110 transmits the composite land value information I15 shown in Figure 31 to the terminal 10 via the network interface 16. In response, the network interface 16 of the terminal 10 receives the composite land value information I15 shown in Figure 31 and outputs it to the control circuit 12. As a result, the control circuit 12 of the terminal 10 acquires the composite land value information I15 shown in Figure 31. As a result, the control circuit 12 of the terminal 10 can display the composite land value information I15 shown in Figure 31.

[0177] The user selects a land value from the composite land value information I15 shown in Figure 31 by operating the operation unit 26 of the terminal 10. As a result, the control circuit 12 of the terminal 10 obtains selected land value information I16, which indicates the land value. The control circuit 12 of the terminal 10 then transmits the selected land value information I16 to the management server 110 via the network interface 16. Accordingly, the network interface 116 of the management server 110 receives the selected land value information I16 and outputs it to the control circuit 112. As a result, the network interface 116 of the management server 110 obtains the selected land value information I16. The network interface 116 of the management server 110 can use the selected land value information I16 as base information I22. The control circuit 112 of the management server 110 performs the processing from step S123 onwards.

[0178] Land price information I5 may have different formats depending on the issuer. Therefore, it may be difficult for the control circuit 112 of the management server 110 to accurately read the land price from land price information I5. To address this, the control circuit 112 of the management server 110 generates composite land price information I15 by combining multiple land price information I5. This allows the user to select a land price by operating the operation unit 26 of the terminal 10.

[0179] (Other embodiments) The system according to the present invention is not limited to systems 1, 1a to 1d, but can be modified within the scope of its gist. Furthermore, the configurations of systems 1, 1a to 1d may be combined in any way.

[0180] In System 1, the memory circuit 114 (memory circuit of one or more computers) of the management server 110 may pre-store the correspondence relationship information I25 (first correspondence relationship information) shown at the bottom of Figure 19. In this case, the correspondence relationship information I25 is set by the user. This eliminates the need for steps S103, S108, S113, S118, S123, and S128. The control circuit 112 (control circuit of one or more computers, first base information acquisition means 112b) of the management server 110 acquires one or more base information I22 (first base information) (step S117). Specifically, the control circuit 112 of the management server 110 acquires acquired information I23 (for example, map information I4) which includes one or more base information I22. The control circuit 112 of the management server 110 (control circuit of one or more computers, first digital document generation information generation means 112c) generates one or more digital document generation information I21 (first digital document generation information) based on one or more base information I22 (first base information) and correspondence relationship information I25 (first correspondence relationship information) (step S119). Specifically, the control circuit 112 of the management server 110 sets the contents of one or more base information I22 (e.g., Station A) to the contents of the digital document generation information I21 corresponding to the second category (e.g., nearest station) included in the base information I22. Then, the control circuit 112 of the management server 110 (control circuit of one or more computers, first display information generation means 112a) generates display information I53 (first display information) so as to include the correspondence relationship information I25 (first correspondence relationship information) (step S133). As a result, the control circuit 112 of the management server 110 does not need to generate correspondence information I25 each time the first digital document D1 is generated.

[0181] In System 1, the user may select the layout of the first digital document D1 from multiple layouts. In this case, the control circuit 112 of the management server 110 (control circuit of one or more computers / layout information acquisition means 112m) acquires layout information indicating the layout selected by the user from among multiple layout patterns. In the process of generating the first digital document D1, the control circuit 112 of the management server 110 (control circuit of one or more computers) generates the first digital document D1 having the layout selected by the user based on the layout information.

[0182] In addition, in systems 1,1a to 1d, the control circuit 112 (one or more computers / update means 112o) of the management server 110 may update the first digital document D1 when one or more base information I22 (first base information) is updated. More specifically, the control circuit 112 of the management server 110 periodically (for example, once a year) queries the copy server 210, road register server 310, map server 410, and land price server 510 to check whether the real estate information I1, copy information I2, road register information I3, map information I4, land price information I5, and urban planning information I6 (acquired information I23) have been updated. Then, if the real estate information I1, the certified copy information I2, the road register information I3, the map information I4, the land value information I5, and the urban planning information I6 are updated, the control circuit 112 of the management server 110 acquires the updated real estate information I1, the certified copy information I2, the road register information I3, the map information I4, the land value information I5, and the urban planning information I6 and generates the first digital document D1.

[0183] Furthermore, if the first digital document D1 is updated, the control circuit 112 of the management server 110 may store the first digital document D1 for each version. In this case, the control circuit 112 of the management server 110 manages the digital document generation information I21, base information I22, acquisition information I23, and correspondence relationship information I25 for each version of the first digital document D1. As a result, the control circuit 112 of the management server 110 can generate display information I53 for each version of the first digital document D1.

[0184] In system 1a, the control circuit 112 of the management server 110 generates the first digital document D1 based on the second digital document D2. In this case, the control circuit 112 of the management server 110 can use multiple types of second digital documents D2 having different formats created by multiple real estate agents. In this case, the user may assign an identifier to the first digital document D1 so that they can identify which of the multiple types of second digital document D2 formats they are using.

[0185] In addition, in systems 1,1a to 1d, the control circuit 112 (one or more computers and first digital document generation means 112n) of the management server 110 may generate the first digital document to include photographic information I7.

[0186] The certified copy server 210 may include multiple servers that store multiple certified copy information I2 from different areas.

[0187] Note that emphasis is not limited to highlighting; it can also be achieved by underlining or changing the color of the text.

[0188] The correspondence information I25 may also be generated by the user operating the control unit 26 of the terminal 10.

[0189] System 1 may include multiple terminals 10.

[0190] Furthermore, the control circuit 112 of the management server 110 does not have to send the first digital document D1 to the terminal 10. The control circuit 112 of the management server 110 may send a URL indicating the storage location of the first digital document D1 to the terminal 10.

[0191] Note that the same base information I22 may be included in multiple different acquired information I23. In such cases, the control circuit 112 of the management server 110 may decide, according to predetermined rules, which acquired information I23's base information I22 will be used to generate the digital document generation information I21. Alternatively, the user may decide, through their operation, which acquired information I23's base information I22 will be used to generate the digital document generation information I21.

[0192] Furthermore, the correspondence indicators 850 and 860 may be displayed when the user clicks on the content of the digital document generation information I21. In this case, the correspondence indicator 850 will be displayed in a way that highlights the content of the digital document generation information I21. The correspondence indicator 850 will be displayed in a way that highlights the content of the base information I22.

[0193] When multiple pairs of correspondence indicators 850,860 are displayed, correspondence indicators 850,860 will be displayed in multiple colors. In this case, corresponding correspondence indicators 850,860 will have the same color.

[0194] Furthermore, the control circuit 112 of the management server 110 may send notification information to the terminal indicating that the price of the property deviates significantly from the fair price. In this case, the control circuit 112 of the management server 110 uses a machine learning model to determine whether the price of the property deviates significantly from the fair price, for example, based on the property's address, land value, and age of the building.

[0195] Furthermore, the format of the first digital document D1 may be customized by the user.

[0196] The display information I53 may be information that simultaneously displays on the display 20 one or more digital document generation information I21 related to real estate used to generate the first digital document D1 relating to real estate transactions, and one or more base information I22 used to generate the one or more digital document generation information I21, as shown in Figure 18, or it may be information that sequentially displays one or more digital document generation information I21 and one or more base information I22 on the display 20. The sequential display of one or more digital document generation information I21 and one or more base information I22 on the display 20 means a display mode in which an image containing one or more digital document generation information I21 and an image containing one or more base information I22 are switched by the user's operation.

[0197] As shown in Figure 8, the certified copy information I2 is on a single sheet, but it may also consist of two or more sheets.

[0198] Furthermore, the correspondence indicators 850 and 860 are not limited to highlighting applied to one or more digital document generation information I21 (first digital document generation information) and one or more base information I22 (first base information). For example, the correspondence indicator 850 is a highlighting applied to the land area box included in the input unit 810, and the correspondence indicator 860 may be an enlarged display of the land area included in the information display unit 820, or a cropped image of the land area included in the information display unit 820.
