DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0019] FIG. 1 is a diagram showing an example of the configuration of a condominium building estimation system 10 according to one embodiment of the present invention.

[0020] As shown in FIG. 1, the condominium building estimation system 10 is a computer system such as a server including a processor 10a, a memory unit 10b, a communication unit 10c, an output unit 10d, and an input unit 10e.

[0021] The processor 10a is a program-controlled device such as a CPU, and executes various information processes according to programs stored in the memory unit 10b. The memory unit 10b is, for example, a storage element such as a ROM or RAM, or a solid-state drive. The memory unit 10b stores programs executed by the processor 10a. The communication unit 10c is a communication interface for sending and receiving data. The output unit 10d is, for example, a display unit such as a display that displays and outputs information according to instructions input from the processor 10a. The input unit 10e is, for example, a mouse, a keyboard, or the like that outputs the contents of operations performed by the user to the processor 10a.

[0022] Fig. 2 is a functional block diagram showing an example of functions implemented in the condominium building estimation system 10 according to this embodiment. Note that the condominium building estimation system 10 according to this embodiment does not need to implement all of the functions shown in Fig. 2, and functions other than the functions shown in Fig. 2 may also be implemented.

[0023] 2, the condominium building estimation system 10 according to this embodiment functionally includes, for example, a house number list data storage unit 20, a condominium register data storage unit 22, a registration application information storage unit 24, a registration information storage unit 26, an estimation unit 28, a list generation unit 30, and a list storage unit 32. The house number list data storage unit 20, the condominium register data storage unit 22, the registration application information storage unit 24, the registration information storage unit 26, and the list storage unit 32 are implemented mainly in the storage unit 10b. The estimation unit 28 and the list generation unit 30 are implemented mainly in the processor 10a.

[0024] The above functions may be implemented by executing a program including instructions corresponding to the above functions, which is installed in the condominium building estimation system 10, which is a computer, on the processor 10a. This program may be supplied to the condominium building estimation system 10 via a computer-readable information storage medium, such as an optical disk, a magnetic disk, a magnetic tape, a magneto-optical disk, or a flash memory, or via the Internet, for example.

[0025] In this embodiment, the house number list data storage unit 20 stores house number list data including a plurality of house number data indicating house numbers, for example. FIG. 3 is a diagram showing an example of house number list data. As shown in FIG. 3, the house number list data according to this embodiment includes a plurality of house number data each indicating the house numbers of different buildings. Here, as shown in FIG. 3, 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 generated by the user of the condominium building estimation system 10 based on the registration information such as all real estate registration items, the registration application information corresponding to the contents of the real estate registration receipt book, the house taxation ledger data obtained by digitizing the house taxation ledger, etc. may be stored in the house number list data storage unit 20.

[0026] In this embodiment, for example, the apartment book data storage unit 22 stores apartment book data, which is electronic data of an apartment book in which the house number and the room number for each of a plurality of rooms are associated with each other.

[0027] Fig. 4 is a diagram showing an example of condominium register data according to this embodiment. As shown in Fig. 4, the condominium register data associates room number data indicating the room number with house number data indicating the house number for a condominium at a given location. In this way, the condominium register data associates room numbers with house numbers, and based on the condominium register data, it is possible to identify the house number corresponding to a specific room number in a building at a specific location, and the room number corresponding to a specific house number.

[0028] In this embodiment, the registration application information storage unit 24 stores registration application information such as the registration application information data exemplified in Fig. 5. The registration application information stored in the registration application information storage unit 24 may include registration application information related to a building identified by a house number indicated in the house number data included in the house number list data.

[0029] Here, data of the registration application information may be acquired in advance via the communication unit 10c 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 registration application information data may be stored in the registration application information storage unit 24.

[0030] Fig. 5 is a diagram showing an example of registration application information data. Each of the registration application information data shown in Fig. 5 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, real estate type data, and outer lot data.

[0031] The acceptance date data is, for example, data indicating the acceptance date of the registration application associated with the registration application information data.

[0032] 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.

[0033] 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 Fig. 5, the property identification data includes prefecture name data, city / ward / town / village name data, oaza / town name data, az / chome data, and lot / house number data.

[0034] The prefecture name data, city / ward / town / village name data, oaza / town name data, zona / chome data, and land / house number data respectively indicate the prefecture name, city / ward / town / village name, oaza / town name, zona / chome data, and land / house number data of the real estate that is the subject of the registration application.

[0035] The land lot and building number data is data indicating the land lot 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.

[0036] 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 specified 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 az / cho / name / chome data corresponds to a character string that represents the location of the real estate.

[0037] The application unit data is, for example, data indicating whether the registration application associated with the registration application information data is made as a single application or as a consecutive application. It corresponds to the entries "single," "consecutive," and "consecutive" in the real estate registration receipt book. The application unit data of the registration application information data associated with the first registration application of the consecutive applications is set to the value "consecutive." 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 "consecutive." 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."

[0038] 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 and the character string indicating the registration purpose in the real estate registration receipt book associated with the registration application information data do not necessarily have to match.

[0039] The real estate type data is, for example, data indicating the type of 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 real estate type data is set to the value "land". If the real estate related to the registration application is a building, the real estate type data is set to the value "building". If the real estate related to the registration application is a condominium building, the real estate type data is set to the value "ward building".

[0040] The external registration data is data that indicates the existence and number of real estate for which a registration application has been made in a single registration application together with the real estate identified by the property identification data. Hereinafter, a registration application for two or more real estate properties in a single registration application will be referred to as a "batch application."

[0041] If there are other properties that have been applied for together, the registration application information will record additional information such as "External 1", "External 2", etc. Here, "External 1" means that there is one property that has been applied for together with the property identified by the property identification data. "External 2" means that there are two properties that have been applied for together with the property identified by the property identification data.

[0042] In this embodiment, for registration application information in which outer stroke information is recorded, the outer stroke data is set to a value of 1 or greater. In this embodiment, for example, the outer stroke data of registration application information data corresponding to registration application information in which outer stroke information "Outside 1" is recorded is set to a value of 1. In addition, the outer stroke data of registration application information data corresponding to registration application information in which outer stroke information "Outside 2" is recorded is set to a value of 2. In addition, in this embodiment, the outer stroke data of registration application information data corresponding to registration application information in which outer stroke information is not recorded is set to a value of 0.

[0043] In this embodiment, it is assumed that the registration application information data related to consecutively applied registration applications are associated with each other in the registration application information data stored in the registration application information storage unit 24. For example, it is assumed that the same group ID is assigned to the registration application information data related to consecutively applied registration applications.

[0044] For example, the same group ID may be assigned to registration application information data whose application unit data value is "consecutive" 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.

[0045] In this embodiment, the registration information storage unit 26 stores, for example, data of registration information. For example, registration information such as all real estate registration details may be acquired in advance via the communication unit 10c from a registration information service that provides information on all real estate registration details in a PDF file, such as a registration information service provided by the General Incorporated Foundation Civil Law Association. Then, registration information data generated by executing a text conversion process on the file may be stored in the registration information storage unit 26.

[0046] In this embodiment, for example, the estimation unit 28 estimates house number data indicating the house number of a condominium from among a plurality of house number data included in the house number list data stored in the house number list data storage unit 20. Here, for example, house number data indicating the house number of a condominium that is not a multi-family home (such as a two-family home or a three-family home) may be estimated. Note that the multi-family home in this embodiment includes a two-family home. Alternatively, house number data indicating the house number of a condominium may be estimated. The estimation process executed by the estimation unit 28 will be described later.

[0047] In this embodiment, the list generation unit 30 generates a list indicating the estimation result by the estimation unit 28, for example. Here, for example, a list of house number data estimated to indicate the house numbers of condominiums may be generated. Also, a list of house number data estimated to indicate the house numbers of condominiums that are not multi-family homes may be generated. Also, data of a house number list estimated to indicate the house numbers of condominiums may be generated. Then, the list generation unit 30 stores the generated list in the list storage unit 32.

[0048] For example, house number list data including a plurality of house number data each indicating a house number of a building in a given area is stored in the house number list data storage unit 20. In this case, in this embodiment, for example, as shown in FIG. 6, the estimation unit 28 executes an estimation process on the house number list data stored in the house number list data storage unit 20 (S101). Then, the list generation unit 30 generates a list based on the execution result of the estimation process in the process shown in S101 (S102). Then, the list generation unit 30 outputs the list generated in the process shown in S102 to the list storage unit 32 (S103).

[0049] Hereinafter, several examples of the estimation process executed in the process shown in S101 and the list generation process executed in the process shown in S102 will be described.

[0050] In the first processing example, in the processing shown in S101, the estimation unit 28 estimates, for example, from among a plurality of house number data included in the house number list data stored in the house number list data storage unit 20, house number data indicating house numbers with branch numbers of three or more digits and house number data having a predetermined number or more of common parts excluding branch numbers from the indicated house numbers, as house number data indicating the house numbers of condominium buildings. Here, the predetermined number may be a number equal to or greater than 4. Then, in the processing shown in S102, the list generation unit 30 generates condominium building house number list data including the house number data estimated to indicate the house numbers of condominium buildings.

[0051] 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. Also, 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.

[0052] For example, when the house number list data shown in FIG. 3 is stored in the house number list data storage unit 20, the condominium building house number list data shown in FIG. 7 is generated by the above-mentioned process.

[0053] In condominiums, it is normal for the room number, which is the house number, to be three or more digits, and it is extremely rare for the part of the house number that corresponds to the branch number to be three or more digits for other reasons. Also, if there are a certain number of buildings that have the same part of their house numbers excluding the branch numbers, it is highly likely that they are condominium buildings that are not multi-family housing.

[0054] In the first processing example, house number data in which the branch number of the house number is three digits or more and house number data in which the part excluding the branch number is common to a certain number or more (for example, four or more) are estimated as house number data indicating the house number of a condominium. Therefore, according to the first processing example, the house number of a building estimated to be a condominium or other condominium can be accurately extracted.

[0055] In addition, users of the condominium building estimation system 10, such as real estate agents, can refer to the condominium building house number list data stored in the list memory unit 32 to determine the house numbers of buildings within a given area that are likely to be condominium buildings.

[0056] In the first processing example, in the process shown in S101, the estimation unit 28 may estimate house number data indicating a house number having three or more digits as house number data indicating a condominium house number from among a plurality of house number data included in the house number list data stored in the house number list data storage unit 20. Then, in the process shown in S102, the list generation unit 30 may generate condominium house number list data including the house number data estimated to indicate the condominium house number.

[0057] For example, when the house number list data shown in Fig. 3 is stored in the house number list data storage unit 20, the condominium house number list data shown in Fig. 8 may be generated by the above-mentioned process. In this way, it is possible to accurately extract house numbers of buildings that are presumed to be condominiums. Furthermore, by referring to the condominium house number list data stored in the list storage unit 32, a user of the condominium building estimation system 10 can ascertain the house numbers of buildings that are likely to be condominiums among the buildings in a given area.

[0058] In the first processing example, in the process shown in S101, the estimation unit 28 may estimate house number data having a predetermined number or more of common house numbers excluding branch numbers from among the multiple house number data included in the house number list data stored in the house number list data storage unit 20 as house number data indicating the house number of a condominium building that is not a multifamily house. Here, the predetermined number may be 4 or more. Then, in the process shown in S102, the list generation unit 30 may generate condominium building house number list data including house number data estimated to indicate the house number of a condominium building that is not a multifamily house.

[0059] In this way, it is possible to accurately extract house numbers of buildings that are estimated to be condominium buildings (but not multi-family homes). Also, by referring to the condominium building house number list data stored in the list storage unit 32, a user of the condominium building estimation system 10 can ascertain house numbers of buildings that are likely to be condominium buildings (but not multi-family homes) among the buildings in a given area.

[0060] In the second processing example, in the process shown in S101, the estimation unit 28 estimates, for example, house number data indicating a house number indicated in the condominium book data stored in the condominium book data storage unit 22, from among a plurality of house number data included in the house number list data stored in the house number list data storage unit 20, as house number data indicating a condominium house number. Then, in the process shown in S102, the list generation unit 30 generates condominium house number list data including the house number data estimated to indicate the house number of a condominium.

[0061] In this case, for example, the estimation unit 28 checks whether or not the house number indicated by each of the multiple house number data included in the house number list data stored in the house number list data storage unit 20 is indicated in the condominium register data. Then, the house number data for which it has been confirmed that the house number is indicated in the condominium register data is estimated to be house number data indicating the house number of a condominium.

[0062] For example, it may be confirmed whether a character string indicated by the house number data included in the house number list data matches a character string obtained by combining a location character string (excluding the condominium name) indicated in the condominium register data, a hyphen, and a character string indicated by any house number data included in the condominium register data. If there is a match, the house number data included in the house number list data may be presumed to be house number data indicating the house number of a condominium.

[0063] For example, when the condominium register data shown in Figure 4 is stored in the condominium register data storage unit 22, if the house number indicated by the house number data included in the house number list data is any of "18-1-1, F Town, E City, D Prefecture," "18-1-2, F Town, E City, D Prefecture," "18-1-3, F Town, E City, D Prefecture," ..., "18-1-9, F Town, E City, D Prefecture," ..., the house number data is presumed to be house number data indicating the house number of a condominium.

[0064] According to the second processing example, it is possible to accurately extract house numbers of buildings that are estimated to be condominiums. Also, by referring to the condominium house number list data stored in the list storage unit 32, the user of the condominium building estimation system 10 can ascertain the house numbers of buildings that are likely to be condominiums among the buildings in a given area.

[0065] In the third processing example, in the processing shown in S101, the estimation unit 28 estimates house number data indicating the house number of a building for which a predetermined number or more registration applications have been submitted by collective application or consecutive application based on the registration application information and which satisfies any one of the following conditions: (1) the use is a ward building and the registration purpose is a title of a condominium building, (2) the use is a ward building and the registration purpose is an indication of a land right, or (3) the use is a building and the registration purpose is division / division, as house number data indicating the house number of a condominium building that is not a multi-family house. Here, the predetermined number may be a number equal to or greater than 4. Then, in the processing shown in S102, the list generation unit 30 generates a condominium building house number list data including the estimated house number data.

[0066] In a third processing example, for example, in the processing shown in S101, as shown in FIG. 9, the estimation unit 28 selects one of the multiple house number data included in the house number list data for which the processing shown in S202 to S209 has not been performed (S201).

[0067] Then, the estimation unit 28 identifies, from among the multiple registration application information data stored in the registration application information memory unit 24, the registration application information data of a building identified by the house number indicated by the house number data selected in the processing shown in S201 (S202).

[0068] Then, the estimation unit 28 determines whether the registration application information data identified in the process shown in S202 is registration application information data relating to a registration application in which a predetermined number (e.g., four or more items) have been registered together (S203).

[0069] In the processing shown in S203, for example, if the value of the outer stroke data included in the registration application information data identified in the processing shown in S202 is 3 or greater, the registration application information data identified in the processing shown in S202 is determined to be registration application information data relating to a registration application in which four or more items are registered collectively.

[0070] For example, if the number of other registration application information data assigned the same group ID as the registration application information data identified in the processing shown in S202 is three or more, the registration application information data identified in the processing shown in S202 is determined to be registration application information data relating to a registration application in which four or more items are registered together.

[0071] For example, if the sum of the number of other registration application information data that are assigned the same group ID as the registration application information data identified in the process shown in S202 and the number of values ​​of the outer line data included in the registration application information data that are assigned the same group ID and whose application unit data value is ``connected destination'' is 3 or more, the registration application information data identified in the process shown in S202 is determined to be registration application information data related to a registration application in which four or more items are registered together.

[0072] If it is determined that the registration application information data identified in the process shown in S202 is not registration application information data relating to a registration application in which a predetermined number or more properties have been registered collectively (S203:N), the estimation unit 28 estimates that the registration application information data identified in the process shown in S202 does not relate to a condominium building that is not a multi-family home (S204).

[0073] If it is determined that the registration application information data identified in the process shown in S202 is registration application information data relating to a registration application in which a predetermined number or more properties have been registered together (S203:Y), the estimation unit 28 checks whether the value of the real estate type data included in the registration application information data identified in the process shown in S202 is “ward property” (S205).

[0074] If it is confirmed that the value of the real estate type data is “condominium” (S205: Y), the estimation unit 28 checks whether the value of the registration purpose data included in the registration application information data identified in the process shown in S202 is either “title of condominium” or “indication of land right” (S206).

[0075] If the value of the registration purpose data included in the registration application information data identified in the process shown in S202 is either the “title of the condominium” or the “indication of land right” (S206: Y), the estimation unit 28 estimates that the registration application information data identified in the process shown in S202 relates to a condominium building that is not a multi-family house (S207).

[0076] If it is confirmed in the process shown in S205 that the value of the real estate type data is not “ward building” (S205:N), the estimation unit 28 confirms whether the value of the real estate type data included in the registration application information data identified in the process shown in S202 is “building” (S208).

[0077] If it is confirmed that the value of the real estate type data is not "building" (S208:N), the estimation unit 28 estimates that the registration application information data identified in the process shown in S202 does not relate to a condominium building that is not a multi-family dwelling (S204).

[0078] If it is confirmed that the value of the real estate type data is "building" (S208: Y), the estimation unit 28 checks whether the value of the registration purpose data included in the registration application information data identified in the processing shown in S202 is "division / section" (S209).

[0079] If the value of the registration purpose data included in the registration application information data identified in the process shown in S202 is “division / division” (S209: Y), the estimation unit 28 estimates that the registration application information data identified in the process shown in S202 is related to a condominium building that is not a multi-family house (S207).

[0080] If the value of the registration purpose data included in the registration application information data identified in the process shown in S202 is not “division / section” (S209:N), the estimation unit 28 estimates that the registration application information data identified in the process shown in S202 does not relate to a condominium building that is not a multi-family home (S204).

[0081] After the process shown in S204 or S207 is executed, the estimation unit 28 checks whether the processes shown in S202 to S209 have been executed for all house number data included in the house number list data (S210).

[0082] If it is confirmed that the process has not been executed for all house number data (S210: N), the process returns to S201.

[0083] If it is confirmed that the process has been executed for all house number data (S210: Y), the process shown in S101 is ended.

[0084] In this case, in the process shown in S102, the list generation unit 30 generates condominium building house number list data including house number data indicating the house numbers of the registration application information data that is presumed to relate to a condominium building that is not a multi-family home.

[0085] In the third processing example, in the processing shown in S202, the estimation unit 28 may acquire the registration application information data of the building identified by the house number indicated by the house number data selected in the processing shown in S201 from the registration application information data providing system via the communication unit 10c. Then, the processing shown in S203 and subsequent processing may be executed for the acquired registration application information data.

[0086] In addition, in the third processing example, it is not necessary to use the house number list data. For example, the registration application information storage unit 24 may store the registration application information data of the buildings in a specific area. Then, the process shown in S203 and the subsequent processes may be executed on the registration application information data.

[0087] That is, the estimation unit 28 may acquire registration application information related to a building. Then, when the registration application information is a building for which a predetermined number or more registration applications have been submitted by collective application or consecutive application, and satisfies any one of the following conditions: the use is a ward building and the registration purpose is a title of a condominium building, the use is a ward building and the registration purpose is an indication of a land right, or the use is a building and the registration purpose is division / division, the estimation unit 28 may estimate the registration application information as registration application information related to a condominium building that is not a multi-family house. Here, the predetermined number may be 4 or more.

[0088] Most multi-family homes, such as two-family homes and three-family homes, have two units, or at most three units. Also, condominiums often have one or more common areas that comply with regulations. In the third processing example, a building whose use and registration purpose meet the above-mentioned conditions and for which a predetermined number or more (e.g., four or more) registration applications have been filed is estimated to be a condominium building that is not a multi-family home, so that the house numbers of buildings estimated to be condominium buildings (but not multi-family homes) can be accurately extracted. Also, by referring to the condominium building house number list data stored in the list storage unit 32, a user of the condominium building estimation system 10 can grasp the house numbers of buildings that are likely to be condominium buildings (but not multi-family homes) among the buildings in a given area.

[0089] In the third processing example, the predetermined number may be set to a number according to the purpose of estimation. Also, the predetermined number may be set to a number according to the type and size of the area to be estimated for the building that is estimated to be a condominium building other than a multi-family house. For example, in an urban area, a large number (e.g., 10) may be set to the predetermined number.

[0090] In the fourth processing example, in the processing shown in S101, the estimation unit 28 estimates, for example, based on the registration information, the house number data indicating the house number of a building related to the registration information in which a title part indicating the display of one building and a character string is shown in the building name column, as the house number data indicating the house number of a condominium building that is not a multi-family house. Then, in the processing shown in S102, condominium building house number list data including the estimated house number data is generated.

[0091] In a fourth processing example, for example, in the processing shown in S101, as shown in FIG. 10, the estimation unit 28 selects one of the multiple house number data included in the house number list data for which the processing shown in S302 to S306 has not been performed (S301).

[0092] Then, the estimation unit 28 identifies the registration information data of a building identified by the house number indicated by the house number data selected in the processing shown in S301 from among the multiple registration information data stored in the registration information storage unit 26 (S302).

[0093] Then, the estimation unit 28 checks whether or not the registration information data identified in the process shown in S302 includes the character string "title section (display of one building)" (S303).

[0094] If the registration information data identified in the process shown in S302 does not contain the string “Title (display of a single building)” (S303:N), the estimation unit 28 estimates that the registration information data identified in the process shown in S302 does not relate to a condominium building that is not a multi-family dwelling (S304).

[0095] When the registration information data identified in the process shown in S302 includes the character string "title section (display of a building)" (S303: Y), the estimation unit 28 checks whether or not a character string is displayed in the building name column of the block including the character string of the title section (display of a building) of the registration information data identified in the process shown in S302 (S305). In the process shown in S305, for example, it is checked whether or not a character string is displayed in the cell to the right of the cell including the character string of the building name in the block including the character string of the title section (display of a building) of the registration information data identified in the process shown in S302.

[0096] If not included (S305: Y), the estimation unit 28 estimates that the registration information data identified in the process shown in S302 does not relate to a condominium building that is not a multi-family dwelling (S304).

[0097] If included (S305: Y), the estimation unit 28 estimates that the registration information data identified in the process shown in S302 is related to a condominium building that is not a multi-family dwelling (S306).

[0098] After the process shown in S304 or S306 has been executed, the estimation unit 28 checks whether or not the process shown in S302 to S306 has been executed for all house number data included in the house number list data (S307).

[0099] If it is confirmed that the process has not been executed for all the house number data (S307: N), the process returns to S201.

[0100] If it is confirmed that the process has been executed for all house number data (S307: Y), the process shown in S101 is ended.

[0101] In this case, in the process shown in S102, the list creation unit 30 creates condominium building house number list data including house number data indicating the house number of the registration information data that is presumed to relate to a condominium building that is not a multi-family home.

[0102] According to the fourth processing example, it is possible to accurately extract house numbers of buildings that are estimated to be condominium buildings (but not multi-family homes). Also, by referring to the condominium building house number list data stored in the list storage unit 32, the user of the condominium building estimation system 10 can grasp house numbers of buildings that are likely to be condominium buildings (but not multi-family homes) among the buildings in a given area.

[0103] In a fourth processing example, the estimation unit 28 may estimate, based on the registration information, house number data indicating the house number of a building related to registration information that includes a title section indicating a building, a character string being indicated in the building name column, and a residence being indicated in the type column of the title section indicating a building for exclusive use, as house number data indicating the house number of a condominium.

[0104] For example, for registration information data that is estimated in the process shown in Figure 10 to relate to a condominium building that is not a multi-family home, the estimation unit 28 may check whether the string "residence" is written in the cell below the cell containing the string "type" in a block that contains the string "title section (indication of the building as an exclusive use portion)."

[0105] If the character string "residence" is written, the estimation unit 28 may estimate that the registration information data is related to a condominium. Then, in the process shown in S102, the list generation unit 30 may generate condominium house number list data including house number data indicating the house numbers of the registration information data estimated to be related to a condominium.

[0106] In this way, it is possible to accurately extract house numbers of buildings that are presumed to be condominiums. Also, by referring to the condominium house number list data stored in the list storage unit 32, the user of the condominium building presumption system 10 can ascertain the house numbers of buildings that are highly likely to be condominiums among the buildings in a given area.

[0107] In addition, in the fourth processing example, it is not necessary to use the house number list data. For example, the registration information storage unit 26 may store the registration information data of the buildings in a predetermined area. Then, the process shown in S303 and the subsequent processes may be executed for the registration application information data.

[0108] That is, the estimation unit 28 may acquire registration information related to a building. Then, when the registration information includes a title section indicating that the information indicates a single building and a character string is indicated in the building name field, the estimation unit 28 may estimate that the registration information is registration information related to a condominium building that is not a multifamily house.

[0109] In addition, if the registration information includes a title section indicating a building, a character string is displayed in the building name column, and the type column of the title section indicating a building for exclusive use indicates a residence, the estimation unit 28 may estimate that the registration information is registration information relating to a condominium.

[0110] It should be noted that the present invention is not limited to the above-described embodiment.

[0111] In this embodiment, any one of the processes described in the first to fourth processing examples above may be executed, or a plurality of the processes may be executed.

[0112] In addition, the processes according to the above-mentioned multiple processing examples may be applied in stages. For example, the process described in the second processing example may be executed for multiple house number data included in the house number list data, and then the process described in the first processing example may be executed for the remaining house number data indicating house numbers of buildings that were not estimated to be condominiums.

[0113] 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]
