[0016] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0017] Fig. 1 is a functional block diagram showing an example of functions implemented in the building sectional estimation system 10 according to this embodiment. Note that the building sectional estimation system 10 according to this embodiment does not need to implement all of the functions shown in Fig. 1, and functions other than those shown in Fig. 1 may also be implemented.

[0018] As shown in Figure 1, the condominium unit estimation system 10 of this embodiment functionally includes, for example, a house number list data storage unit 20, a registration application information storage unit 22, a building-related data generation unit 24, a building-related data storage unit 26, a registration information storage unit 28, a condominium register data storage unit 30, an estimation unit 32, a list generation unit 34, and a generated list storage unit 36.

[0019] The building sectional estimation system 10 may be configured with a known computer including, for example, a CPU, memory, a communication interface, an input device, and a display. The functional blocks shown in Fig. 1 are realized by executing a building sectional estimation program in the building sectional estimation system 10, which is a computer. The building sectional estimation program may be stored in various computer-readable information storage media such as semiconductor memory and loaded from the media into the building sectional estimation system 10. Alternatively, it may be downloaded to the building sectional estimation system 10 via a data communication line such as the Internet.

[0020] In this embodiment, the house number list data storage unit 20 stores house number list data including, for example, multiple house number data indicating house numbers. FIG. 2 is a diagram showing an example of house number list data. As shown in FIG. 2, the house number list data according to this embodiment includes multiple house number data, each indicating the house number of a different building. Here, as shown in FIG. 2, the house number data may include a character string indicating the location of the building and a character string indicating the house number of the building. For example, the house number list data storage unit 20 may store house number list data generated by a user of the condominium estimation system 10 based on registration information such as all real estate registration details, registration application information corresponding to the contents of a real estate registration receipt book, house tax register data obtained by digitizing a house tax register, etc. Furthermore, the house number list data storage unit 20 may store house number list data including house number data indicating the house numbers of buildings and condominiums within a given area (hereinafter referred to as the target area).

[0021] In this embodiment, the registration application information storage unit 22 stores registration application information such as the registration application information data exemplified in Fig. 3. The registration application information stored in the registration application information storage unit 22 may include registration application information for real estate within the target area, which is related to registration applications made within a given period. Note that in this embodiment, the registration application information storage unit 22 does not include registration application information for all real estate (including buildings and condominiums) within the target area, but includes registration application information for some of the real estate within the target area.

[0022] Here, data of the registration application information may be acquired in advance via a communication interface from a registration application information data providing system in which registration application information corresponding to the contents of the real estate registration receipt book managed by the Legal Affairs Bureau is registered as data. Then, the acquired data of the registration application information may be stored in the registration application information storage unit 22.

[0023] Fig. 3 is a diagram showing an example of registration application information data. Each piece of registration application information data shown in Fig. 3 corresponds to one real estate registration application. The registration application information data according to this embodiment includes acceptance date data, acceptance number, property identification data, application unit data, registration purpose data, use data, and outline data.

[0024] The acceptance date data is, for example, data indicating the acceptance date of the registration application associated with the registration application information data.

[0025] The reception number is, for example, a number set according to the order in which the registration application was received in the year in which the registration application associated with the registration application information data was made.

[0026] The property identification data is, for example, data for identifying real estate that is the subject of a registration application associated with the registration application information data. As shown in Figure 3, the property identification data includes prefecture name data, city / ward / town / village name data, oaza / town name data, azuma / chome data, and lot / house number data.

[0027] The prefecture name data, city / ward / town / village name data, oaza / town name data, zona / chome data, and land / house number data are data that respectively indicate the prefecture name, city / ward / town / village name, oaza / town name, zona / chome data, land / house number data, and land number data.

[0028] The land lot and building number data is data indicating the land lot number of the real estate if the real estate subject to the registration application is land. Also, the land lot and building number data is data indicating the building number of the real estate if the real estate subject to the registration application is a building.

[0029] In this embodiment, the location of the real estate that is the subject of the registration application associated with the registration application information data can be identified based on the property identification data. For example, a character string that combines the values ​​of prefecture name data, city / ward / town / village name data, oaza / town name data, and azami / chome data corresponds to the character string that represents the location of the real estate.

[0030] The application unit data is, for example, data indicating whether the registration application associated with the registration application information data was made as a single application or as a series of applications. It corresponds to the entries "single," "sequential," and "sequential" in the real estate registration receipt book. The application unit data of the registration application information data associated with the first registration application of a series of registration applications is set to the value "sequential." The application unit data of the registration application information data associated with the registration application made together with the application unit data is set to the value "sequential." Furthermore, the application unit data of the registration application information data associated with the registration application made as a single application is set to the value "single."

[0031] 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 character string of the value of the registration purpose data included in the registration application information data does not necessarily have to match the character string indicating the registration purpose in the real estate registration receipt book associated with the registration application information data.

[0032] The use data is, for example, data indicating the use (type) of the real estate related to the registration application associated with the registration application information data. If the real estate related to the registration application is land, the value "land" is set as the use data. If the real estate related to the registration application is a building, the value "building" is set as the use data. If the real estate related to the registration application is a condominium, the value "ward building" is set as the use data.

[0033] The external registration data is data that indicates the existence and number of real estate properties for which registration applications have been made through a single registration application, along with the real estate properties identified by the property identification data. Hereinafter, a registration application for two or more real estate properties through a single registration application will be referred to as a bulk application.

[0034] If there are other properties that have been applied for together, the registration application information will record additional information such as "External 1" or "External 2." Here, "External 1" means that there is one property that has been applied for together with the property identified by the property identification data. Also, "External 2" means that there are two properties that have been applied for together with the property identified by the property identification data.

[0035] In this embodiment, for registration application information in which outer line information is recorded, the outer line data is set to a value of 1 or greater. In this embodiment, for example, the outer line data of registration application information data corresponding to registration application information in which outer line information of "Outside 1" is recorded is set to a value of 1. Furthermore, the outer line data of registration application information data corresponding to registration application information in which outer line information of "Outside 2" is recorded is set to a value of 2. Furthermore, in this embodiment, the outer line data of registration application information data corresponding to registration application information in which outer line information is not recorded is set to a value of 0.

[0036] In this embodiment, it is assumed that the registration application information data relating to consecutively filed registration applications are associated with each other in the registration application information data stored in the registration application information storage unit 22. For example, it is assumed that the same group ID is assigned to the registration application information data relating to consecutively filed registration applications.

[0037] For example, the same group ID may be assigned to registration application information data whose application unit data value is "continuous" and one or more registration application information data whose application unit data value is "consecutive" and whose reception number follows the registration application information data.

[0038] In this embodiment, the structure relationship data generation unit 24 generates structure relationship data in which, for example, the lot number of a land and the house number of a building that is a structure on the land are associated with each other. Figure 4 is a diagram showing an example of the structure relationship data. As shown in Figure 4, the structure relationship data includes, for example, lot number data and house number data.

[0039] The building-related data generation unit 24 may, for example, use the API of a service provided by the Civil Law Association Registration Information Service, which responds with building numbers from street addresses, to execute a building-related building number query process for each of all parcel numbers in the target area. Alternatively, the building-related data generation unit 24 may execute the building-related building number query process for each of the parcel numbers listed in the G-space information data maintained by the G-space Information Center. Here, a single building number may be identified for a single parcel number, or multiple building numbers may be identified. For example, if multiple buildings or buildings including multiple condominiums are built on a parcel identified by a single parcel number, multiple building numbers may be identified for the buildings on the parcel. Then, the building relationship data generation unit 24 may generate building relationship data that associates the land lot data indicating the land lot number with the house number data indicating the house number identified in this manner, and store the generated building relationship data in the building relationship data storage unit 26.

[0040] Alternatively, the building-related data generation unit 24 may extract the registration application information data whose value of the use data is "ward building" from among the registration application information stored in the registration application information storage unit 22. Then, the building-related data generation unit 24 may execute a site lot number inquiry process to identify the lot number of the land on which the building identified by the house number is built, for the house number indicated in the registration application information data, using an API of a service that responds with a location number from a house number, provided by the Civil Law Association Registration Information Providing Service.

[0041] Here, for one house number, only one lot number of the land on which the building identified by that house number stands may be specified, or multiple lot numbers may be specified. For example, for a building that straddles two parcels identified by two parcel numbers, two lot numbers of the land on which the building stands will be specified.

[0042] The structure relationship data generation unit 24 may then generate structure relationship data that associates the structure number data indicating the structure number with the lot number data indicating the lot number identified in this manner, and store the generated structure relationship data in the structure relationship data storage unit 26. The structure relationship data generation unit 24 may then execute the structure house number inquiry process described above for the lot number. As described above, for one lot number, only one house number may be identified for the building on the land identified by the lot number, or multiple house numbers may be identified. The structure relationship data generation unit 24 may then generate structure relationship data that associates the lot number data indicating the lot number with the house number data indicating the lot number identified in this manner, and store the generated structure relationship data in the structure relationship data storage unit 26.

[0043] In this case, after the above-mentioned processing is executed, the following may be repeated a predetermined number of times: execution of a building house number inquiry processing for the land number identified as described above; generation of building relationship data based on the results of the building house number inquiry processing; execution of a site land number identification processing for the house number identified by the building house number inquiry processing; and generation of building relationship data based on the results of the site land number identification processing.

[0044] Alternatively, the structure-related data generation unit 24 may extract registration application information data in which the value of the use data is "condominium," in which a predetermined number or more (for example, four or more) of applications for registration have been made collectively through a single application or a series of applications, and in which the value of the registration purpose data is "unit building title" or "preservation of ownership" from among the registration application information data stored in the registration application information storage unit 22. Then, the structure-related data generation unit 24 may store the structure-related data generated by executing the above-mentioned lot number inquiry process and structure building number inquiry process based on the registration application information data extracted in this way in the structure-related data storage unit 26.

[0045] As mentioned above, for one lot number, there may be one or more buildings on the land identified by that lot number. Also, for one house number, there may be one or more lot numbers on the land on which the building identified by that house number stands.

[0046] In the example of Figure 4, the lot number data with the value "D763-1, C-cho, B-city, A-prefecture" is associated with six house number data with the values ​​"D763-1-101, C-cho, B-city, A-prefecture", "D763-1-102, C-cho, B-city, A-prefecture", "D763-1-201, C-cho, B-city, A-prefecture", "D763-1-202, C-cho, B-city, A-prefecture", "D763-1-301, C-cho, B-city, A-prefecture", and "D763-1-302, C-cho, B-city, A-prefecture". This example corresponds to an example in which only one lot number of the land on which the building identified by that house number stands is specified for one house number.

[0047] 4, the combination of the land lot data whose value is "D763-6, C-cho, B-city, A-prefecture" and the land lot data whose value is "D763-7, C-cho, B-city, A-prefecture" is associated with six house number data whose values ​​are "D763-6-1, C-cho, B-city, A-prefecture," "D763-6-2, C-cho, B-city, A-prefecture," "D763-6-3, C-cho, B-city, A-prefecture," "D763-6-4, C-cho, B-city, A-prefecture," "D763-6-5, C-cho, B-city, A-prefecture," and "D763-6-6, C-cho, B-city, A-prefecture." This example corresponds to an example in which multiple land lot numbers are identified for one house number on which a building identified by that house number stands.

[0048] 4, the parcel number data having a value of "D763-7, C-town, B-city, A-prefecture" is associated with the house number data having a value of "D763-6-7, C-town, B-city, A-prefecture." In this manner, in this embodiment, the combination of the parcel number data having a value of "D763-6, C-town, B-city, A-prefecture" and the parcel number data having a value of "D763-7, C-town, B-city, A-prefecture" and the parcel number data having a value of "D763-7, C-town, B-city, A-prefecture" may be managed as separate parcel number data, and each parcel number data may be associated with different house number data.

[0049] In this embodiment, the building relation data storage unit 26 stores, for example, the building relation data described above.

[0050] In this embodiment, the registration information storage unit 28 stores registration information such as all real estate registration details, which can be obtained by accessing a registration information service provided by, for example, the General Incorporated Foundation Civil Law Association. The registration information service provides the condominium estimation system 10 with information on all real estate registration details, for example, in a file in PDF format. In this embodiment, the condominium estimation system 10 then performs a text conversion process on the file. In this embodiment, data of the registration information corresponding to the content of the text generated by the text conversion process (hereinafter referred to as registration information data) is stored in the registration information storage unit 28.

[0051] In this embodiment, the apartment register data storage unit 30 stores, for example, apartment register data, which is electronic data of an apartment register in which the house number and room number for each of the rooms in each of the multiple buildings are associated with each other. In this way, in this embodiment, the house number and room number of the rooms in each building can be identified.

[0052] In this embodiment, for example, the estimation unit 32 estimates house number data indicating the house number of a condominium from among multiple house number data included in the house number list data stored in the house number list data storage unit 20.

[0053] Here, as described below, the estimation unit 32 may identify the building number of the condominium based on registration application information related to the condominium registration application. Then, the estimation unit 32 may identify the lot number of the land on which the building identified by the identified building number stands based on the building relationship data. Then, the estimation unit 32 may estimate the building number associated with the identified lot number in the building relationship data as the building number of the condominium.

[0054] In this embodiment, the list generation unit 34 generates a list indicating the estimation results by the estimation unit 32. Here, for example, a list of house number data estimated to indicate house numbers of condominiums may be generated. The list generation unit 34 then stores the generated list in the generated list storage unit 36.

[0055] An example of the flow of processing performed in the building section estimation system 10 according to this embodiment will be described below with reference to the flow chart shown in FIG.

[0056] In the following description, for example, it is assumed that house number list data including a plurality of house number data each indicating the house numbers of buildings within the target area is stored in the house number list data storage unit 20. Furthermore, it is assumed that structure-related data associating the lot numbers of land within the target area with the house numbers of buildings on the land is stored in the structure-related data storage unit 26. It is also assumed that registration application information data relating to registration applications for real estate within the target area made during a given period is stored in the registration application information storage unit 22. However, it is assumed that registration application information data relating to registration applications for some real estate within the target area is not stored in the registration application information storage unit 22.

[0057] First, the estimation unit 32 selects one of the house number data included in the house number list data stored in the house number list data storage unit 20 for which the processes shown in S102 to S104 have not been performed (S101).

[0058] Then, the estimation unit 32 checks whether or not there is registration application information data for a condominium identified by the house number indicated by the house number data selected in the process shown in S101, from among the multiple registration application information data stored in the registration application information storage unit 22 (S102). Here, for example, it is checked whether or not there is registration application information data in which the house number indicated by the house number data selected in the process shown in S101 matches a character string obtained by combining a character string that is the value of prefecture name data, a character string that is the value of city / ward / town / village name data, a character string that is the value of oaza / town / village name data, a character string that is the value of azame / name / chome data, and a character string that is the value of lot / house number data, and the value of use data is "kuken".

[0059] If it is not confirmed that the file exists (S102: N), the process returns to S101.

[0060] If it is confirmed that it exists (S102: Y), the estimation unit 32 identifies the land number associated with the house number indicated by the house number list data selected in the processing shown in S101 in the building relationship data (S103).

[0061] Then, the estimation unit 32 estimates the house number associated in the building relation data with the lot number identified in the process shown in S103 as the house number of the condominium (S104).

[0062] Then, the estimation unit 32 checks whether or not the processes shown in S102 to S104 have been executed for all house number list data stored in the house number list data storage unit 20 (S105).

[0063] If the processes shown in S102 to S104 have not been executed for all house number list data (S105: N), the process returns to the process shown in S101.

[0064] If it is confirmed that the processes shown in S102 to S104 have been executed for all house number list data (S105: Y), the list generation unit 34 generates sectioned building house number list data, which is a list of house numbers estimated as house numbers of sectioned buildings in the process shown in S104, and stores the generated sectioned building house number list data in the generated list storage unit 36 ​​(S106), and the process shown in this processing example is terminated. Figure 6 is a diagram showing an example of a sectioned building house number list generated in this way.

[0065] If multiple land lot numbers are identified in the process shown in S103, the process shown in S104 will estimate the house number of the condominium that is associated with the combination of the multiple land lot numbers in the building relationship data.

[0066] In the process shown in S102 above, the estimation unit 32 may further check whether or not there is registration application information data for a building that is not a condominium, identified by the house number indicated by the house number data selected in the process shown in S101, from among the multiple registration application information data stored in the registration application information storage unit 22. Here, for example, it is checked whether or not there is registration application information data in which the house number indicated by the house number data selected in the process shown in S101 matches a character string obtained by combining a character string that is the value of prefecture name data, a character string that is the value of city / ward / town / village name data, a character string that is the value of oaza / town / village name data, a character string that is the value of azame / name / chome data, and a character string that is the value of lot / house number data, and the value of use data is "building."

[0067] If the existence of registration application information data for a building that is not a condominium unit, identified by the house number indicated by the house number data selected in the process shown in S101, is confirmed, the estimation unit 32 may exclude the house number indicated by the house number data from the house numbers estimated as the house numbers of the condominium unit. In this case, the house number will not be included in the condominium unit house number list data generated in the process shown in S106.

[0068] In this way, the estimation unit 32 may exclude house numbers that are identified as house numbers of buildings that are not condominium buildings based on the registration application information from house numbers that are estimated to be house numbers of condominium buildings.

[0069] In this embodiment, the estimation unit 32 may estimate the house number of the condominium from among the house numbers of the condominiums estimated as described above.

[0070] For example, the estimation unit 32 may identify the number of house numbers other than the house numbers of buildings that are not condominium buildings that are associated in the building relationship data with the land number of the land on which a building identified by a house number estimated as the house number of a condominium building is built.

[0071] For example, suppose that "D763-1-101, C-cho, B-city, A-prefecture" is identified as the building number of a condominium based on the registration application information. In this case, the parcel number of the land on which the condominium stands is identified as "D763-1, C-cho, B-city, A-prefecture" based on the building-related data shown in Figure 4. Then, the six building numbers associated with the parcel number in the building-related data are identified as "D763-1-101, C-cho, B-city, A-prefecture," "D763-1-102, C-cho, B-city, A-prefecture," "D763-1-201, C-cho, B-city, A-prefecture," "D763-1-202, C-cho, B-city, A-prefecture," "D763-1-301, C-cho, B-city, A-prefecture," and "D763-3-302, C-cho, B-city, A-prefecture." Furthermore, suppose that there is no registration application information data for any of these six building numbers that is not a condominium and is identified by the corresponding building number. In this case, "6" is specified as the number of the house number mentioned above.

[0072] Then, when the number of house numbers identified in this way is equal to or greater than a predetermined number (for example, 4), the estimation unit 32 estimates the house numbers as house numbers of condominiums. In this case, all of the six house numbers mentioned above are estimated as house numbers of condominiums.

[0073] Furthermore, the estimation unit 32 may estimate a house number that is estimated as the house number of a condominium building and has a branch number of three or more digits as the house number of a condominium building. For example, if the character string indicated by the house number data contains one hyphen, the part to the right of the hyphen corresponds to the branch number. Furthermore, if the character string indicated by the house number data contains two or more hyphens, the part to the right of the rightmost hyphen corresponds to the branch number.

[0074] For example, suppose the condominium house number list shown in Figure 6 is generated. In this case, the following six numbers are estimated to be condominium house numbers: "D763-1-101, C-cho, B-city, A-prefecture," "D763-1-102, C-cho, B-city, A-prefecture," "D763-1-201, C-cho, B-city, A-prefecture," "D763-1-202, C-cho, B-city, A-prefecture," "D763-1-301, C-cho, B-city, A-prefecture," and "D763-3-302, C-cho, B-city, A-prefecture."

[0075] In addition, the estimation unit 32 may estimate the house number of a condominium as the house number of a condominium, which is the house number estimated as the house number of a condominium building and is shown in the condominium register data stored in the condominium register data storage unit 30.

[0076] In addition, the estimation unit 32 may estimate the house number as the house number of a condominium if the building identified by the house number estimated as the house number of a condominium is a building for which the use is a ward building, the registration purpose is the title of the condominium, and more than a predetermined number of registration applications have been filed through a single application or consecutive applications.

[0077] For example, if there is registration application information data relating to a registration application for a condominium identified by a house number that is presumed to be the house number of the condominium and that satisfies all of the following conditions: (1) the value of the use data is "ward building," (2) the value of the registration purpose data is "title of the condominium," and (3) the registration application information data is relating to a bulk application or a series of applications (i.e., there are multiple registration application information data assigned the same group ID as the registration application information data, or the value of the outer line data of the registration application information data is 1 or greater), the house number may be presumed to be the house number of a condominium.

[0078] The estimation unit 32 may also identify the registration information data of the building identified by the house number estimated as the house number of the condominium stored in the registration information storage unit 28. Then, if the value corresponding to the entry in the "House number of exclusive use portion" column in the registration information data (the value written to the right of the entry "House number of exclusive use portion" in the real estate registration details) represents a predetermined number (for example, 4) or more of house numbers, the estimation unit 32 may estimate the house number as the house number of the condominium.

[0079] In addition, in this embodiment, the estimation unit 32 may estimate the house numbers assigned to each of the multiple buildings for the house number of the condominium (or the house number of the condominium) estimated as described above.

[0080] Here, the estimation unit 32 may estimate the house number of a condominium included in each of the multiple buildings based on the contents of the house number column of the exclusive portion shown in the registration information of the building identified by the house number estimated as the house number of the condominium.

[0081] For example, the estimation unit 32 may identify, from among the multiple registration information data stored in the registration information storage unit 28, the registration information data of a building identified by the house number estimated as the house number of the condominium. The estimation unit 32 may then estimate, as the house number of a condominium included in one building, a value corresponding to the entry in the “House Number of Exclusively Owned Part” column in the registration information data (the value written to the right of the entry “House Number of Exclusively Owned Part” in the complete real estate registration information). The estimation unit 32 may also identify a lot number associated with the house number estimated as the house number of the condominium in the building-related data. The estimation unit 32 may then identify multiple house numbers associated with the identified lot number in the building-related data. The estimation unit 32 may then estimate, from among the multiple house numbers identified in this way, at least one house number other than the house number estimated as the house number of the condominium included in one building as the house number of a condominium included in another building.

[0082] Alternatively, the estimation unit 32 may estimate, among the house numbers of sectional buildings (or house numbers of condominiums) estimated as described above, a plurality of house numbers that contain the same predetermined building identification symbol as the house numbers of sectional buildings included in one building. Examples of building identification symbols include "-A", "-B", "-C", "-A", "-B", "-C", "-A", "-I", "-U", "-I", "-B", "-C", and the like.

[0083] Furthermore, for example, among the house numbers of condominiums (or house numbers of condominiums) estimated as described above, multiple house numbers where a house number indicating a shared area and a house number indicating a private area coexist may be estimated as house numbers of condominiums included in one building. For example, multiple house numbers where "-1" indicating a shared area and "-1-***" (where * is any number) indicating a private area coexist may be estimated as house numbers of condominiums included in one building.

[0084] Alternatively, if building information is recorded in the condominium register data stored in the condominium register data storage unit 30, the estimation unit 32 may estimate the house number of a condominium building in the same building based on the building information recorded in the condominium register.

[0085] According to this embodiment, as explained above, the house number of a condominium can be accurately estimated by estimating the house number of the condominium using the building-related data.

[0086] Furthermore, the specific character strings and numerical values ​​described above, as well as the specific character strings in the drawings, are merely examples, and the present invention is not limited to these character strings and numerical values. [Explanation of symbols]
