Summary of the Invention

Problems to be Solved by the Invention

[0004] Even if all items of real estate registration are changed, the above-mentioned business operators are not notified of this. Therefore, in order for the above-mentioned business operators to align the real estate registration information managed in the database with all items of the current real estate registration, it is necessary to compare each of the real estate registration information being managed with all items of the current real estate registration, which is time-consuming.

[0005] Here, if it is possible to estimate a part of the corresponding all items of real estate registration that have been changed from the real estate registration information being managed by referring to the registration application information representing the contents described in the real estate registration acceptance book of the legal affairs bureau, it is possible to expect a reduction in the labor of managing the real estate registration information.

[0006] However, when multiple real estate registration applications are filed together, information such as the location, lot number, and house number of properties other than the representative property is not registered in the registration application information. Therefore, it is not possible to identify properties other than the representative property based solely on the registration application information.

[0007] However, in this case, along with information indicating the representative property, external parcel information such as "External 1" and "External 2," which indicates the existence of registration applications for properties other than the representative property, is recorded as registration application information. If the property corresponding to the external parcel information can be estimated, more property registration information for which the entire property registration details have been changed can be estimated by referring to the registration application information. This would further reduce the effort required to manage property registration information.

[Figure 2A] It is a diagram showing an example of the data of registration information. [Figure 2B] It is a diagram showing an example of the data of registration information. [Figure 3]This figure shows an example of registration application data. [Figure 4] This is a functional block diagram showing an example of a function implemented in a registration information data management system according to one embodiment of the present invention. [Figure 5] This flowchart shows an example of the processing flow in a registration information data management system relating to one embodiment of the present invention. [Modes for carrying out the invention]

[0027] One embodiment of the present invention will be described in detail below with reference to the drawings.

[0028] Figure 1 shows an example of the overall configuration of a computer network according to one embodiment of the present invention. As shown in Figure 1, the following are connected to a computer network 18 such as the Internet: a registration information data management system 10, a registration application information data provision system 12, a registration information provision system 14, and a corresponding information database 16, all of which are centered around computers.

[0029] The registration information data management system 10 is a computer system used by users such as real estate agents and financial institutions. In this embodiment, the registration information data management system 10 registers registration information such as the registration information of real estate owned by the user's customers, and the registration information of all real estate belonging to the area under the jurisdiction of the Legal Affairs Bureau to which the user belongs. In the following description, it will be assumed that the registration information data management system 10 has registered data on the registration information of real estate owned by the user's customers.

[0030] As shown in Figure 1, the registration information data management system 10 includes a processor 10a, a storage unit 10b, a communication unit 10c, an output unit 10d, and an input unit 10e.

[0031] The processor 10a is a program control device such as a CPU, which performs various information processing according to the program stored in the memory unit 10b.

[0032] The memory unit 10b is, for example, a memory element such as ROM or RAM, or a hard disk drive. The memory unit 10b stores programs that are executed by the processor 10a.

[0033] The communication unit 10c is a communication interface for exchanging data with, for example, the registration application information data provision system 12, the registration information provision system 14, and the corresponding information database 16 via the computer network 18. The registration information data management system 10 sends and receives information with the registration application information data provision system 12, the registration information provision system 14, and the corresponding information database 16 via the communication unit 10c.

[0034] The output unit 10d is, for example, a display unit such as a display that outputs information according to instructions input from the processor 10a, or an audio output unit such as a speaker that outputs sound.

[0035] The input unit 10e is, for example, a game controller, touchpad, mouse, keyboard, microphone, etc., which outputs the details of the user's actions to the processor 10a.

[0036] The registration application information data provision system 12 is a computer system in which registration application information, equivalent to the contents of a real estate registration receipt book managed by, for example, a Legal Affairs Bureau, is registered as data. The registration application information data provision system 12 provides the requested registration application information data to a computer system, such as the registration information data management system 10, in response to a request from that computer system.

[0037] The registration information provision system 14 is a computer system that provides registration information provision services, for example, by a general incorporated foundation such as the Civil Legal Affairs Association. The registration information provision system 14 provides registration information, such as all real estate registration details, to a computer system, for example, a registration information data management system 10, in response to a request from said computer system.

[0038] In this embodiment, the registration information provision system 14 provides the registration information data management system 10 with information on all real estate registration details, for example, in a PDF file. In this embodiment, the registration information data management system 10 then performs a text conversion process on the file. In this embodiment, registration information data corresponding to the content of the text generated by the text conversion process is registered in the registration information data management system 10.

[0039] The correspondence information database 16 according to this embodiment stores multiple correspondence information records that show the correspondence between two different types of real estate.

[0040] In the following explanation, it is assumed that the correspondence information database 16 stores multiple land parcel-number-house information comparison data sets, which associate a string representing the location of a building with the building's house number, and a string representing the location of the building's site with the site's land parcel number. The land parcel-number-house information comparison data corresponds to an example of the correspondence information described above. In other words, the land parcel-number-house information comparison data can also be described as data that associates a string representing the location of land with the land parcel number, and a string representing the location of a building that is related to the land with the building's house number.

[0041] Hereinafter, the land parcel number of a building's site will be referred to as the building's site parcel number. The correspondence information database 16 according to this embodiment stores land parcel house information comparison data that associates a string representing the location of a building with the building's house number, and a string representing the location of the building's site with the building's site parcel number, not only for existing buildings but also for buildings that have already been destroyed.Hereinafter, the combination of a string representing the location of a building with the building's house number will be expressed as "building location + house number," and the combination of a string representing the location of the building's site with the building's site parcel number will be expressed as "site location + site parcel number."

[0042] In this embodiment, the corresponding information database 16, upon receiving "building location + house number" transmitted from the registration information data management system 10, returns to the registration information data management system 10 "site location + site lot number" for one or more plots of land associated with the building identified by the "building location + house number".

[0043] It should be noted that a single house number may correspond to the site of a building that is adjacent to multiple plots of land. For example, this situation occurs when a building is built across plots of land identified by multiple adjacent plot numbers. In such cases, the correspondence information database 16, upon receiving the "building location + house number," returns to the registration information data management system 10 multiple "site locations + plot numbers" that correspond to the "building location + house number."

[0044] Furthermore, in response to receiving "site location + site lot number" transmitted from the registration information data management system 10, the corresponding information database 16 returns to the registration information data management system 10 "building location + house number" for one or more buildings associated with the land identified by "site location + site lot number".

[0045] It should be noted that multiple buildings may be associated with a single lot number. For example, this situation occurs when multiple buildings are built on a lot associated with a single lot number, or when a building that stood on a lot associated with a single lot number is rebuilt and a new building is constructed on that lot. In such cases, the correspondence information database 16, upon receiving the "lot number + lot number" information, returns to the registration information data management system 10 multiple "building locations + house numbers" associated with the "lot number + lot number" information.

[0046] In this embodiment, the corresponding information database 16 may be included in the registration information provision system 14. For example, the corresponding information database 16 may be included in a computer system that provides registration information provision services, such as the Civil Legal Affairs Association.

[0047] Figures 2A and 2B show examples of registration information data registered in the registration information data management system 10. Note that one piece of registration information data is represented by the entirety of Figures 2A and 2B.

[0048] The registration information data according to this embodiment is associated with the complete real estate registration information for one property, provided by the registration information provision system 14. Figures 2A and 2B show the registration information data associated with the complete real estate registration information for land. As shown in Figures 2A and 2B, the registration information data according to this embodiment includes customer ID, title section data, rights section (Part A) data, and rights section (Part B) data. In the registration information data, deleted values ​​are underlined.

[0049] The customer ID shown in Figure 2A is the identification information of a user of the registration information data management system 10. The registration information data registered in the registration information data management system 10 according to this embodiment is grouped by customer ID. In other words, in this embodiment, the same customer ID is assigned to the registration information data of real estate owned by the same customer. In this embodiment, the customer ID is set by the user.

[0050] The title section data shown in Figure 2A corresponds to the content of the title section of the corresponding real estate registration. The title section data includes display type data, preparation date data, real estate number data, map number data, boundary identification data, and location data.

[0051] The display type data is the data indicating the type of real estate, written in parentheses to the right of the title section of the complete real estate registration. The preparation date data, real estate number data, map number data, boundary identification data, and location data are data that indicate the contents of the preparation, real estate number, map number, boundary identification, and location sections of the complete real estate registration, respectively.

[0052] Furthermore, the registration information data associated with the complete real estate registration information for a building includes location map number data, which indicates the location map number described in the title section of the complete real estate registration, instead of map number data.

[0053] Furthermore, the title section data includes one or more combinations of land parcel number data, land category data, land area data, and cause and date [registration date] data.

[0054] The land number data, land category data, land area data, and cause and date [registration date] data are data that represent the contents of the land number, land category, land area, cause and date [registration date] described in the title section of the complete real estate registration, respectively.

[0055] Furthermore, for registration information data associated with the complete real estate registration information for buildings, the title section data will contain one or more combinations of house number data, type data, structure data, floor area data, cause and date [registration date] data, instead of the combination of land number data, land category data, land area data, and cause and date [registration date] data. The house number data, type data, structure data, floor area data, and cause and date [registration date] data are data that represent the contents of the house number, type, structure, floor area, cause and date [registration date] in the title section of the complete real estate registration information, respectively.

[0056] The rights section (Section A) data shown in Figure 2B corresponds to the content of the rights section (Section A) of the corresponding real estate registration. The rights section (Section A) data includes one or more combinations of rank number, purpose of registration data, date of receipt data, receipt number, rights holder, and other matters data.

[0057] The rank number and registration purpose data are data indicating the rank number and the content of the registration purpose in the rights section (Section A) of the complete real estate registration, respectively. The acceptance date data and acceptance number are data indicating the acceptance date and the content of the acceptance number included in the rights section (Section A) of the complete real estate registration, respectively. The rights holder and other matters data are data indicating the content of the rights holder and other matters in the rights section (Section A) of the complete real estate registration.

[0058] The rights section (Section B) data shown in Figure 2B corresponds to the content of the rights section (Section B) of the corresponding real estate registration. The rights section (Section B) data includes one or more combinations of rank number, registration purpose data, reception date data, reception number, rights holder, and other matters data.

[0059] The rank number and registration purpose data are data indicating the rank number and the content of the registration purpose in the rights section (Section B) of the real estate registration. The acceptance date data and acceptance number are data indicating the content of the acceptance date and acceptance number included in the rights section (Section B) of the real estate registration. The rights holder and other matters data are data indicating the content of the rights holder and other matters in the rights section (Section B) of the real estate registration.

[0060] Furthermore, the registration information data according to this embodiment may include joint collateral register data corresponding to the contents of the joint collateral register for all real estate registration matters.

[0061] Figure 3 shows an example of registration application information data. Each of the registration application information data shown in Figure 3 corresponds to one real estate registration application. The registration application information data according to this embodiment includes the date of receipt data, receipt number, property identification data, application unit data, registration purpose data, real estate type data, and parcel data.

[0062] The acceptance date data is, for example, data indicating the acceptance date of the registration application associated with the registration application information data.

[0063] The reception number is, for example, a number assigned according to the order in which the registration application was received in the year that the registration application associated with the registration application information data was made.

[0064] Property identification data is, for example, data used to identify the real estate subject to the registration application that is associated with the registration application information data. As shown in Figure 3, property identification data includes prefecture name data, city / ward / town / village name data, district name data, sub-district name data, and land number / house number data.

[0065] The prefecture name data, city / ward / town / village name data, Oaza / town name data, sub-district name / block data, and land number / house number data are, respectively, data indicating the prefecture name, city / ward / town / village name, Oaza / town name, sub-district name or block, and land number or house number of the real estate subject to the registration application.

[0066] The land parcel number and house number data indicates the land parcel number of the property in question if the property subject to the registration application is land. Furthermore, if the property subject to the registration application is a building, the land parcel number and house number data indicates the house number of that building.

[0067] In this embodiment, the location of the real estate subject to the registration application, which is associated with the registration application information data, can be identified based on the property identification data. For example, a string formed by concatenating the values ​​of prefecture name data, city / ward / town / village name data, district name data, and sub-district name data corresponds to a string representing the location of the real estate.

[0068] Application unit data indicates, for example, whether the registration application associated with the registration application information data was made as a single application or as a series of applications. This corresponds to the entries "single," "series," and "continuous" in the real estate registration receipt book. The application unit data of the registration application information data associated with the first registration application in a series of applications will be set to the value "series." The application unit data of the registration application information data associated with the registration application submitted together with that application unit data will be set to the value "continuous." In addition, the application unit data of the registration application information data associated with a single application will be set to the value "single."

[0069] The registration purpose data is, for example, data indicating the purpose of the registration application associated with the registration application information data. Note that the string value of the registration purpose data included in the registration application information data does not necessarily have to match the string representing the registration purpose in the real estate registration receipt book associated with the registration application information data.

[0070] Real estate type data is data that indicates the type of real estate related to the registration application, for example, which is associated with the registration application information data. If the real estate related to the registration application is land, the value "land" will be set in the real estate type data. If the real estate related to the registration application is a building, the value "building" will be set in the real estate type data.

[0071] The external parcel data is data that indicates the existence and number of properties for which registration applications have been filed in a single registration application, along with the properties identified by the property identification data. Hereafter, registration applications for two or more properties in a single registration application will be referred to as a consolidated application.

[0072] If there are other properties included in the bulk application, the registration application information will record information about the other properties, such as "External 1" or "External 2." Here, "External 1" means that there is one property included in the bulk application along with the property identified by the property identification data. "External 2" means that there are two properties included in the bulk application along with the property identified by the property identification data.

[0073] In this embodiment, for registration application information in which outer parcel information is recorded, a value of 1 or more is set for the outer parcel data. In this embodiment, for example, the outer parcel data of registration application information data corresponding to registration application information in which outer parcel information of "Outer 1" is recorded will be set to a value of 1. Also, the outer parcel data of registration application information data corresponding to registration application information in which outer parcel information of "Outer 2" is recorded will be set to a value of 2. Furthermore, in this embodiment, the outer parcel data of registration application information data in which outer parcel information is not recorded will be set to a value of 0.

[0074] When a Legal Affairs Bureau accepts a real estate registration application, the registration information, such as the complete real estate registration details, is updated according to the content of the application. Although the user is not notified of this update to the complete real estate registration details, it is expected that the updated complete real estate registration details can be accurately estimated using the registration application information data. For example, it is conceivable to estimate the registration information data that corresponds to the updated complete real estate registration details by including the location data value and land number data value corresponding to the property identification data value in the registration application information data. Alternatively, for example, it is conceivable to estimate the registration information data that corresponds to the updated complete real estate registration details by including the location data value and house number data value corresponding to the property identification data value in the registration application information data.

[0075] However, even in this case, properties that are included in a single application along with properties identified by property identification data, and for which the registration application information data does not contain information that would allow for the identification of the property subject to registration, cannot be identified solely from the registration application information data.

[0076] Therefore, in this embodiment, it is possible to estimate real estate for which the information that can identify the real estate subject to the registration application is not shown in the registration application information data, even though the application was submitted in a single application along with the real estate identified by the property identification data, as described below.

[0077] The following will further explain the functions of the registration information data management system 10 according to this embodiment and the processing performed by the registration information data management system 10, focusing on the estimation of real estate that has been applied for together with real estate identified by property identification data.

[0078] Figure 4 is a functional block diagram showing an example of the functions implemented in the registration information data management system 10 according to this embodiment. Note that not all of the functions shown in Figure 4 are required to be implemented in the registration information data management system 10 according to this embodiment, and other functions may also be implemented.

[0079] As shown in Figure 4, the registration information data management system 10 according to this embodiment functionally includes, for example, a registration information storage unit 20, a registration application information storage unit 22, a registration application information request unit 24, a registration application information acquisition unit 26, a registration information identification unit 28, an external parcel-corresponding real estate estimation unit 30, a current status confirmation unit 32, and a registration information update unit 34. The registration information storage unit 20 and the registration application information storage unit 22 are mainly implemented using the storage unit 10b. The registration application information request unit 24 is mainly implemented using the processor 10a, a communication unit 10c, an output unit 10d, and an input unit 10e. The registration application information acquisition unit 26 and the current status confirmation unit 32 are mainly implemented using the communication unit 10c. The registration information identification unit 28 and the registration information update unit 34 are mainly implemented using the processor 10a. The external parcel-corresponding real estate estimation unit 30 is mainly implemented using the processor 10a and the communication unit 10c. In this embodiment, the registration information data management system 10 will serve as a real estate estimation system corresponding to parcel data, estimating real estate that corresponds to parcel data.

[0080] The above functions may be implemented by executing a program containing instructions corresponding to the above functions, which is installed on the computer-based registration information data management system 10, on the processor 10a. This program may be supplied to the registration information data management system 10 via a computer-readable information storage medium such as an optical disc, magnetic disc, magnetic tape, magneto-optical disc, or flash memory, or via the internet or the like.

[0081] In this embodiment, the registration information storage unit 20 stores registration information, such as the registration information data illustrated in Figures 2A and 2B.

[0082] In this embodiment, the registration application information storage unit 22 stores registration application information, such as the registration application information data illustrated in Figure 3.

[0083] In this embodiment, the registration application information request unit 24 requests registration application information. The registration application information request unit 24 sends a search command associated with search conditions entered by the user via the input unit 10e to the registration application information data provision system 12, for example, on a search screen (not shown) displayed on the output unit 10d. Examples of search conditions include the range of values ​​for the acceptance date data and the range of values ​​for the property identification data.

[0084] The registration application information data provision system 12 then identifies one or more registration application information data that satisfy the search conditions associated with the search command, in response to receiving the search command transmitted by the registration application information request unit 24. The registration application information data provision system 12 then transmits the identified registration application information data to the registration information data management system 10.

[0085] In this embodiment, the registration application information acquisition unit 26 acquires registration application information, for example. The registration application information acquisition unit 26 receives registration application information data transmitted by the registration application information data provision system 12 and stores it in the registration application information storage unit 22. In this embodiment, the registration application information acquired by the registration application information acquisition unit 26 includes registration application information in which parcel information is recorded.

[0086] In this embodiment, the registration information identification unit 28 identifies, for example, the registration information of a real estate that is the subject of a registration application, from among the multiple pieces of registration information stored in the registration information storage unit 20, and which is indicated in the registration application information acquired by the registration application information acquisition unit 26. Here, the registration information data of the real estate indicated in the registration application information data acquired by the registration application information acquisition unit 26 is identified. Here, the registration information identification unit 28 identifies, for example, a combined location string obtained by combining the values ​​of the city / ward / town / village name data, the large district name / town name data, and the district name / chome data included in the registration application information data acquired by the registration application information acquisition unit 26. The registration information identification unit 28 also replaces the hyphens included in the value of the land number / house number data with "number". Then, the registration information identification unit 28 identifies registration information data that includes the value of the identified combined location string as the value of the location data, and includes the value of the replaced land number / house number data as the value of the land number data or house number data. However, the method for identifying the real estate registration information of a property that is the subject of a registration application, provided that the registration application information acquired by the registration application information acquisition unit 26 contains information that can identify the real estate that is the subject of a registration application, is not limited to this method. The registration information of a property that is the subject of a registration application, provided that the registration application information acquired by the registration application information acquisition unit 26 contains information that can identify the real estate that is the subject of a registration application, may be identified by other methods.

[0087] In this embodiment, the Outer Parcel Corresponding Real Estate Estimation Unit 30 estimates the real estate that corresponds to the outer parcel information, for example, with respect to the registration application information that contains the outer parcel information, which is acquired by the registration application information acquisition unit 26.

[0088] In this embodiment, the Outer Parcel-Related Real Estate Estimation Unit 30 identifies, for example, a real estate that is identified as a specific real estate in the registration application information obtained by the registration application information acquisition unit 26, which contains information that allows for the identification of the real estate subject to the registration application. In the case of the registration application information exemplified in Figure 3, the land identified by the property identification data (A Prefecture B City Oaza C Aza D763-1) corresponds to the specific real estate. Hereafter, the type of specific real estate will be referred to as Type 1. For example, in the case of the registration application information exemplified in Figure 3, Type 1 is land.

[0089] Then, in this embodiment, the Outer Parcel Corresponding Real Estate Estimation Unit 30 identifies, for example, a second type of real estate that is associated with a specific real estate that is the first type of real estate, as the corresponding real estate in correspondence information that shows correspondence between two different types of real estate.

[0090] For example, as described above, the correspondence information database 16 stores land parcel house information comparison data in which a combination of a string representing the location of a building and the building's house number is associated with a combination of a string representing the location of the building's site and the land parcel number of the site. Here, if the first type is land as described above, then the second type will be a building.

[0091] In this case, the Outer Parcel Corresponding Real Estate Estimation Unit 30 may identify a building that is in a superstructure relationship with the land, which is the specified real estate, as the corresponding real estate. For example, the Outer Parcel Corresponding Real Estate Estimation Unit 30 may transmit to the Corresponding Information Database 16 a string of characters corresponding to the location and lot number of the specified real estate, which is the land, namely "site location + site lot number". Then, in response to such transmission, the Corresponding Information Database 16 may return a building identified by "building location + house number" for one or more buildings on which the specified real estate is the site, and identify that building as the corresponding real estate.

[0092] In this embodiment, the Outer Parcel Corresponding Real Estate Estimation Unit 30 estimates, for example, a first type of real estate that is different from the specific real estate that is associated with the corresponding real estate in the correspondence information, as the real estate that is associated with the Outer Parcel Information.

[0093] For example, if the corresponding real estate consists of one or more buildings, the Outer Parcel Corresponding Real Estate Estimation Unit 30 may identify the land on which each of the one or more buildings is located. The Outer Parcel Corresponding Real Estate Estimation Unit 30 may then estimate that the land among the multiple lands identified in this way, which is different from the land that is the specific real estate, is the land to be associated with the Outer Parcel Information. For example, for each of the one or more corresponding real estate (buildings), the Outer Parcel Corresponding Real Estate Estimation Unit 30 may transmit to the Corresponding Information Database 16 a string of characters corresponding to the location and house number of the corresponding real estate, namely "building location + house number". The Outer Parcel Corresponding Real Estate Estimation Unit 30 may then identify the land identified by "site location + site lot number" for the one or more lands that are the site of the corresponding real estate, which is returned from the Corresponding Information Database 16 in response to the transmission. The Outer Parcel Corresponding Real Estate Estimation Unit 30 may then estimate that the land among the lands identified in this way for each of the one or more corresponding real estate (buildings), which is different from the land that is the specific real estate, is the real estate to be associated with the Outer Parcel Information.

[0094] In this embodiment, the current status confirmation unit 32 confirms, for example, all real estate registration details of the current status of the real estate associated with the registration information. Here, the current status confirmation unit 32 may also confirm all real estate registration details of the current status of the real estate associated with the parcel information. For example, the current status confirmation unit 32 may obtain a file of information on all real estate registration details identified based on the "site location + site lot number" of the real estate estimated to be associated with the parcel information from the registration information provision system 14.

[0095] In this embodiment, the registration information update unit 34 updates the registration information stored in the registration information storage unit 20 based on the current status confirmed by the current status confirmation unit 32. Here, the registration information update unit 34 may also update the registration information of real estate that is estimated to be associated with the parcel information, which is stored in the registration information storage unit 20, based on the current status confirmed by the current status confirmation unit 32. The registration information update unit 34 performs a text conversion process on the file of real estate registration information received by the current status confirmation unit 32. Then, the registration information update unit 34 updates the registration information data by, for example, reflecting the content of the text generated by the text conversion process in the value of the registration information data.

[0096] Below, an example of the processing flow performed in the registration information data management system 10 according to this embodiment will be explained with reference to the flowchart illustrated in Figure 5.

[0097] First, the registration application information request unit 24 sends a search command associated with the search conditions to the registration application information data provision system 12 (S101).

[0098] Then, the registration application information acquisition unit 26 receives one or more registration application information data transmitted by the registration application information data provision system 12 in response to the receipt of the search command transmitted in the process shown in S101 (S102).

[0099] The registration information identification unit 28 then selects one registration application information data from the registration application information data obtained in the process shown in S102 that has not had the processes shown in S104 to S111 performed (S103). In this example, the real estate in which the registration application information data selected in the process shown in S103 contains information that can identify the real estate that is the subject of the registration application will be called the specified real estate. The type of specified real estate will be called the first type.

[0100] The registration information identification unit 28 then identifies the registration information data stored in the registration information storage unit 20 that corresponds to the registration application information data selected in the process shown in S103 (S104).

[0101] The Outer Parcel-Related Real Estate Estimation Unit 30 then checks the value of the outer parcel data included in the registration application information data selected in the process shown in S103 (S105).

[0102] Let's assume here that the value of the outer parcel data is confirmed to be 1 or greater. In this case, the outer parcel corresponding real estate estimation unit 30 accesses the corresponding information database 16 and identifies the second type of real estate that is associated with the first type of specific real estate associated with the registration application information selected in the process shown in S103 as the corresponding real estate (S106).

[0103] Then, the Outer Parcel Corresponding Real Estate Estimation Unit 30 accesses the Corresponding Information Database 16 and estimates a first type of real estate, which is different from the specific real estate associated with the registration application information selected in the process shown in S103 and is associated with the corresponding real estate identified in the process shown in S106, as the real estate associated with the outer parcel information of the registration application information data of the specific real estate. (S107).

[0104] Then, the registration information identification unit 28 identifies the registration information data of the real estate that has been estimated to be associated with the parcel information in the process shown in S107, which is stored in the registration information storage unit 20 (S108).

[0105] The process shown in S105 confirms that the value of the outer parcel data is 0 (S105:N), or the process shown in S108 is completed. In this case, the current status confirmation unit 32 sends a request to the registration information provision system 14 to transmit the information on all real estate registration matters corresponding to the registration information data identified in the processes shown in S104 and S108 (S109). The current status confirmation unit 32 then receives the information on all real estate registration matters transmitted by the registration information provision system 14 in response to the receipt of the request to transmit the information on all real estate registration matters (S110).

[0106] Then, the registration information update unit 34 updates the registration information data identified in the processes shown in S104 and S108 based on the complete real estate registration information received in the process shown in S110 (S111).

[0107] The registration information identification unit 28 then checks whether all of the registration application information data obtained in the process shown in S102 has been selected in the process shown in S103 (S112). If not all of the registration application information data has been selected in the process shown in S103 (S112:N), the process returns to the process shown in S103. If all of the registration application information data has been selected in the process shown in S103 (S112:Y), the process shown in this example is terminated.

[0108] In the practical application of real estate registration, when applying for registration of two or more properties located within the jurisdiction of the same registry office, if the "purpose of registration," "cause of registration," and the "date" of the said cause of registration are the same, a single application is permitted. However, if the applicants for the registration applications are not the same, the application is not eligible for a single application.

[0109] Furthermore, if a specific property is land, there is a high probability that the building on that land has the same owner as the land itself, and that the multiple plots of land (multiple adjacent plots of land) on which this building stands also have the same owner.

[0110] In this embodiment, focusing on the points mentioned above, we decided to estimate that a piece of land different from the specific piece of land associated with the corresponding building is the piece of land associated with the outer parcel information.

[0111] Furthermore, in this embodiment, the type of real estate that can identify the real estate subject to the registration application is indicated in the registration application information in which the parcel information is recorded may be a building. For example, this case occurs when the value of the real estate type data included in the registration application information data is "building".

[0112] In this case, the Outer Parcel Corresponding Real Estate Estimation Unit 30 may identify at least one plot of land that is the site of a building that is a specific real estate as the corresponding real estate. For example, the Outer Parcel Corresponding Real Estate Estimation Unit 30 may transmit to the Corresponding Information Database 16 a string of characters corresponding to the location and house number of the specific real estate that is a building, namely "building location + house number". Then, in response to such transmission, the Corresponding Information Database 16 may return a plot of land identified by "site location + site lot number" for one or more plots of land that are the site of the specific real estate, and identify that plot as the corresponding real estate.

[0113] Furthermore, the Outer Parcel Corresponding Real Estate Estimation Unit 30 may estimate a building that is in a superstructure relationship with any of the corresponding properties, but is different from the specific property, as a property that can be associated with the Outer Parcel Information. For example, the Outer Parcel Corresponding Real Estate Estimation Unit 30 may transmit to the Corresponding Information Database 16 a string of characters corresponding to the location and lot number of each of the one or more corresponding properties (land). Then, the Outer Parcel Corresponding Real Estate Estimation Unit 30 may identify a building identified by "Building Location + House Number" for one or more buildings on which the corresponding property is located, which is returned from the Corresponding Information Database 16 in response to the transmission. Then, the Outer Parcel Corresponding Real Estate Estimation Unit 30 may estimate a building that is different from the specific property, among the buildings identified in this way for each of the one or more corresponding properties (land), as a property that can be associated with the Outer Parcel Information.

[0114] In this case, the current status confirmation unit 32 may obtain a file of real estate registration information from the registration information provision system 14, which is identified based on the "building location + house number" of the building that is presumed to be real estate associated with the parcel information. The registration information update unit 34 may then update the registration information of the real estate that is presumed to be real estate associated with the parcel information, which is stored in the registration information storage unit 20, by reflecting the content of the text generated by the text conversion process performed on the file obtained in this way into the value of the registration information data.

[0115] If a specific property is a building, it is highly likely that the land on which this building stands has the same owner as the building itself, and that multiple buildings on the same land also have the same owner.

[0116] Focusing on the points mentioned above, in this case, we decided to presume that the building associated with the land, which is the corresponding real estate, is different from the building that is the specific real estate, and is associated with the land, as the real estate associated with the parcel information.

[0117] Furthermore, in this embodiment, the correspondence information stored in the correspondence information database 16 is not limited to the land parcel house information comparison data described above. For example, for agricultural land areas in suburban areas, the correspondence information stored in the correspondence information database 16 may be cultivated area land comparison data that shows the correspondence between cultivated areas and the land included in said cultivated areas. Specifically, for example, the correspondence information database 16 may store cultivated area land comparison data in which a cultivated area polygon showing the geographical extent of a cultivated area associated with a pre-established cultivated area identifier (ID) and a polygon showing the geographical extent of land surrounded by a boundary associated with the location and land parcel number are superimposed.

[0118] By referring to the cultivated area land comparison data, it is possible to identify the ID of the cultivated area to which a piece of land identified by its location and land number belongs. Furthermore, by referring to the cultivated area land comparison data, it is possible to identify the location and land number of a piece of land within the cultivated area identified by a specified ID.

[0119] Furthermore, if the above-mentioned cultivated area land comparison data is stored in the corresponding information database 16, and the above-mentioned type of specific real estate is land, the outer parcel corresponding real estate estimation unit 30 may access the corresponding information database 16 to identify the cultivated area containing the land, which is the specific real estate, as the corresponding real estate.

[0120] Furthermore, the Outer Parcel Corresponding Real Estate Estimation Unit 30 may estimate that land that is included in the cultivated area, which is the corresponding real estate, and is different from the land that is the specific real estate, is land that can be associated with the Outer Parcel Information.

[0121] If the specific property in question is land, there is a high probability that the owner of this land and the owner of other land included in the cultivated area containing this land are the same person.

[0122] Focusing on the points mentioned above, in this case, we decided to presume that the land associated with the outer parcel information is a different piece of land from the specific piece of land that is associated with the cultivated area, which is the corresponding piece of real estate.

[0123] Furthermore, for example, in mountainous areas, the correspondence information stored in the correspondence information database 16 may be sub-unit land comparison data that shows the correspondence between a sub-unit and the land included in that sub-unit. Specifically, for example, the correspondence information database 16 may store sub-unit land comparison data in which a sub-unit polygon indicating the geographical extent of a sub-unit associated with a pre-established sub-unit identifier (ID) and a polygon indicating the geographical extent of land surrounded by a boundary associated with the location and land number are superimposed.

[0124] By referring to the sub-unit land parcel data, it is possible to identify the ID of the sub-unit to which a parcel identified by its location and lot number belongs. Furthermore, by referring to the sub-unit land parcel data, it is possible to identify the location and lot number of a parcel within the scope of a sub-unit identified by a specified ID.

[0125] Furthermore, if the above-mentioned sub-lot land comparison data is stored in the correspondence information database 16, and the above-mentioned type of specific real estate is land, the outer parcel corresponding real estate estimation unit 30 may access the correspondence information database 16 to identify the sub-lot containing the land which is the specific real estate as the corresponding real estate.

[0126] Furthermore, the Outer Parcel Corresponding Real Estate Estimation Unit 30 may estimate that a parcel of land different from the specific real estate land, which is included in the sub-unit that is the corresponding real estate, is a parcel of land that can be associated with the Outer Parcel Information.

[0127] If the specific real estate is land, it is highly likely that the owner of this land and the owner of a different plot of land included in the sub-compartment containing this land are the same person.

[0128] Focusing on the points mentioned above, in this case, we decided to presume that the land parcel associated with the information on the outer parcel is a different piece of land from the specific piece of land that is associated with the sub-parcel that is the corresponding piece of land.

[0129] Furthermore, in this embodiment, the property estimation unit 30 corresponding to the outer parcel may estimate the property that corresponds to the outer parcel information based on the registration information of the specified property described above.

[0130] For example, the real estate estimation unit 30 corresponding to the outer parcel may identify the address of the owner of the specific real estate as shown in the registration information. Here, for example, the address shown for the owner in the rights holder and other matters data of the rights section (Section A) of the registration information data of the specific real estate may be identified as the address of the owner of the specific real estate. Alternatively, for example, the address shown for the owner at the bottom of the rights holder and other matters data of the rights section (Section A) of the registration information data of the specific real estate (the address of the most recent owner of the specific real estate) may be identified as the address of the owner of the specific real estate.

[0131] Furthermore, the Outer Parcel Corresponding Real Estate Estimation Unit 30 may estimate the real estate identified based on the address of the owner of the specific real estate as the real estate associated with the outer parcel information if the real estate indicated in the title section of the registration information of the specific real estate (for example, the real estate identified by the location data included in the title section data of the registration information data of the specific real estate) is different from the real estate identified based on the address of the owner of the specific real estate.

[0132] For example, if Figures 2A and 2B represent the registration information data of a specific property, then "1-2-3 F-cho, E-city" is identified as the address of the owner of the specific property. However, the property shown in the title section of the registration information of the specific property is different from the property identified based on the owner's address. Therefore, in this case, the property identified by the owner's address (1-2-3 F-cho, E-city) is presumed to be the property associated with the parcel information.

[0133] The owner of a specific property and the owner of a property identified by the address of the owner of that specific property are highly likely to be the same person.

[0134] Taking the above points into consideration, in this case, we decided to presume that the property identified based on the address of the owner of the specific property is the property that corresponds to the information on the outer parcel of land.

[0135] Furthermore, in this embodiment, the parcel-related real estate estimation unit 30 may identify a real estate as a specific real estate in which information that can identify the real estate subject to the registration application is indicated in the first registration application information in which the parcel-related information is recorded. The registration information identification unit 28 may then identify the registration information of the specific real estate identified in this manner. The parcel-related real estate estimation unit 30 may then identify the acceptance date and acceptance number of a registration application different from the registration application related to the first registration application information, as indicated in the registration information of the specific real estate. For example, in the example of Figure 2B, a combination of the acceptance date data value and the acceptance number value included in the rights section (Section A) data or the rights section (Section B) data of the registration information data of the specific real estate may be identified that is different from the combination of the acceptance date data value and the acceptance number value included in the first registration application information in which the parcel-related information is recorded.

[0136] Furthermore, the external property estimation unit 30 may identify a second registration application information identified by the specified acceptance date and acceptance number.

[0137] Here, for example, the registration application information request unit 24 may request registration application information data from the registration application information data provision system 12, which includes a combination of the reception date data value and the reception number value for a registration application different from the registration application related to the first registration application information. The registration application information acquisition unit 26 may then acquire the registration application information data transmitted from the registration application information data provision system 12 in response to the request. This registration application information data corresponds to the second registration application information described above.

[0138] Here, suppose that the second registration application information contains information about the parcel of land, and that the second registration application information contains information that can identify the real estate subject to the registration application, and that this real estate is different from the real estate in the first registration application information that contains information that can identify the real estate subject to the registration application. In this case, the parcel of land corresponding real estate estimation unit 30 may estimate that the real estate in the second registration application information contains information that can identify the real estate subject to the registration application is the real estate that corresponds to the parcel of land information. For example, the real estate identified by the property identification data in the second registration application information may be estimated as the real estate that corresponds to the parcel of land information.

[0139] It is highly probable that the owner of a specific property and the owner of another property related to a separate registration application, as indicated in the registration information for that specific property, are the same person.

[0140] Taking the above points into consideration, in this case, we have decided to presume that the property to which the property subject to the registration application is identified in the second registration application information, which is a different registration application from the first registration application information, and which is shown in the registration information associated with the first registration application information, is the property to which the parcel information is associated.

[0141] Furthermore, in this embodiment, a specific property is defined as a property in which information that can identify the property subject to the registration application is shown in the first registration application information in which the parcel information is recorded.

[0142] In this case, the Outer Parcel Corresponding Real Estate Estimation Unit 30 may identify a second registration application information relating to a series of applications, which is different from the first registration application information, in which information that can identify a specific real estate is shown. For example, a second registration application information data may be identified in which the property identification data value is the same as the first registration application information data, and the application unit data value is "sequential" or "continuous".

[0143] Furthermore, the Outer Parcel Corresponding Real Estate Estimation Unit 30 may estimate that real estate that can identify the real estate subject to the registration application is shown in the third registration application information related to the registration application filed in conjunction with the second registration application information as real estate that can be associated with the outer parcel information.

[0144] Here, for example, in the registration application information data stored in the registration application information storage unit 22, the registration application information data related to the registration applications that have been submitted in succession may be linked to each other. For example, the registration application information data related to the registration applications that have been submitted in succession may be assigned the same group ID.

[0145] For example, the same group ID may be assigned to registration application information data where the value of the application unit data is "sequential," and to one or more registration application information data where the value of the application unit data is "consecutive," and whose reception number follows that registration application information data.

[0146] Furthermore, a different registration application information data, which is assigned the same group ID as the second registration application information data, may be identified as the third registration application information data.

[0147] Furthermore, the real estate identified based on the property identification data of the third registration application information data may be presumed to be the real estate corresponding to the parcel information.

[0148] It is highly probable that the owner of a specific property and the owner of a property related to a separate registration application filed concurrently with the registration application for that specific property are the same person.

[0149] Taking the above points into consideration, in this case, we decided to presume that the real estate related to the third registration application information, which is filed concurrently with the second registration application information that contains information that can identify the specific real estate, is the real estate that corresponds to the parcel information recorded in the first registration application information that contains information that can identify the specific real estate.

[0150] As explained above, this embodiment makes it possible to accurately estimate the real estate corresponding to the parcel information. Then, the contents of the current real estate registration are confirmed, and the registration information data is updated based on the contents of the real estate registration, focusing on the registration information data of the real estate for which it is presumed that the entire real estate registration has been updated. In this way, this embodiment makes it possible to reduce the effort required to manage the registration information data compared to the case where all the registration information data stored in the registration information storage unit 20 is compared with the current real estate registration and the registration information data is updated.

[0151] However, the present invention is not limited to the embodiments described above.

[0152] Furthermore, the division of roles among the registration information data management system 10, the registration application information data provision system 12, the registration information provision system 14, and the corresponding information database 16 is not limited to those described above. For example, in the above embodiment, the registration application information data registered in the registration application information data provision system 12 may be stored in the registration information data management system 10.
