Summary of the Invention

Problems to be Solved by the Invention

[0004] When a customer dies, property such as real estate owned by the customer is inherited. However, simply checking the registration information of the real estate before inheritance registration may not be able to determine whether the real estate has become the subject of inheritance with the latest owner of the real estate shown in the registration information as the decedent.

[0005] The present invention has been made in view of the above circumstances, and one of its objects is to provide an inheritance occurrence estimation system, an inheritance occurrence estimation method, and a program that can accurately estimate whether the real estate shown in the registration information has become the subject of inheritance with the latest owner of the real estate shown in the registration information as the decedent.

[Figure 6D] This figure shows an example of owner management data. [Modes for carrying out the invention]

[0011] One embodiment of the present invention will be described in detail below with reference to the drawings.

[0012] Figure 1 is a functional block diagram showing an example of the functions implemented in the inheritance occurrence estimation system 10 according to this embodiment. Note that not all of the functions shown in Figure 1 are required to be implemented in the inheritance occurrence estimation system 10 according to this embodiment, and other functions may also be implemented.

[0013] As shown in Figure 1, the inheritance occurrence estimation 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 information acquisition unit 24, an owner identification unit 26, an inheritance occurrence estimation unit 28, and an association unit 30.

[0014] The inheritance estimation system 10 may be composed of a known computer, for example, including a CPU, memory, communication interface, input device, and display. The functional blocks shown in Figure 1 are realized by the execution of an inheritance estimation program in the inheritance estimation system 10, which is a computer. The inheritance estimation program may be stored in various computer-readable information storage media such as semiconductor memory and loaded from such media into the inheritance estimation system 10. Alternatively, it may be downloaded into the inheritance estimation system 10 via a data communication line such as the Internet.

[0015] In this embodiment, the registration information storage unit 20 stores, for example, multiple pieces of registration information. For example, registration information data may be obtained in advance via a communication interface from a registration information provision service provided by a general incorporated foundation such as the Civil Legal Affairs Association. The registration information data, which is the obtained registration information data, may then be stored in the registration information storage unit 20.

[0016] FIG. 2A and FIG. 2B are diagrams showing an example of registration information data. It is assumed that one piece of registration information data is represented by the entirety of FIG. 2A and FIG. 2B.

[0017] The registration information data according to the present embodiment is associated with information on all matters of real estate registration for one piece of real estate. Note that FIG. 2A and FIG. 2B show registration information data associated with information on all matters of land real estate registration. As shown in FIG. 2A and FIG. 2B, the registration information data according to the present embodiment includes acquisition date and time data, title section data, and rights section (section A) data. In the registration information data, underlines are drawn for the erased values.

[0018] The acquisition date and time data shown in FIG. 2A is data indicating the date and time when the registration information data was acquired from the registration information providing service.

[0019] The title section data shown in FIG. 2A is data corresponding to the description content of the title section of all matters of the corresponding real estate registration. The title section data includes display type data, preparation date and time data, real estate number data, map number data, boundary specification data, and location data.

[0020] The display type data is data indicating the type of real estate, which is described in parentheses on the right side of the description in the title section of all matters of the real estate registration. The preparation date and time data, real estate number data, map number data, boundary specification data, and location data are data indicating the description contents of the preparation, real estate number, map number, boundary specification, and location in the title section of all matters of the real estate registration, respectively.

[0021] Note that, for the registration information data associated with information on all matters of real estate registration for a building, instead of the map number data, location map number data indicating the description content of the location map number in the title section of all matters of the real estate registration is included.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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, acceptance date data, acceptance number, rights holder and other matters data. Hereinafter, the combination of rank number, purpose of registration data, acceptance date data, acceptance number, rights holder and other matters data will be referred to as Section A element data. The rights section (Section A) data shown in Figure 2B includes three Section A element data.

[0026] 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.

[0027] Furthermore, the registration information data according to this embodiment may include the rights section (Section B) corresponding to the contents of the rights section (Section B) of the corresponding real estate registration, and joint collateral register data corresponding to the contents of the joint collateral register of the corresponding real estate registration.

[0028] In this embodiment, the registration information storage unit 20 is assumed to store registration information data for a predetermined prefecture (for example, Prefecture A).

[0029] In this embodiment, the registration application information storage unit 22 stores, for example, multiple registration application information. Here, registration application information data corresponding to the contents of the real estate registration receipt book managed by the Legal Affairs Bureau may be obtained in advance via a communication interface from a registration application information data provision system in which registration application information is registered as data. The obtained registration application information data may then be stored in the registration application information storage unit 22.

[0030] Figure 3 shows an example of registration application information data. Figure 4 shows another example of registration application information data. The registration application information data exemplified in Figures 3 and 4 are each associated with one real estate registration application. The registration application information data according to this embodiment includes reception date data, reception number, property identification data, application unit data, registration purpose data, usage data, and parcel 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 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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."

[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 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.

[0039] The usage data is, for example, data indicating the usage (type) of the real estate related to the registration application, which is associated with the registration application information data. If the real estate related to the registration application is land, the value "land" is set in the usage data. If the real estate related to the registration application is a building, the value "building" is set in the usage data. If the real estate related to the registration application is a condominium unit, the value "condominium unit" is set in the usage data.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] Furthermore, in this embodiment, the registration application information data stored in the registration application information storage unit 22 is associated with each other in relation to the registration application information data related to the registration applications that have been submitted in succession. For example, the registration application information data related to the registration applications that have been submitted in succession are assigned the same group ID.

[0044] 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.

[0045] In this embodiment, the registration information acquisition unit 24 acquires, for example, real estate registration information. The registration information acquisition unit 24 acquires, for example, one of several registration information data stored in the registration information storage unit 20. Hereinafter, the registration information data acquired by the registration information acquisition unit 24 in this manner will be referred to as the "target registration information data." Furthermore, the real estate associated with the target registration information data will be referred to as the "target real estate."

[0046] In this embodiment, the owner identification unit 26 identifies the latest owner of the property of interest indicated in the registration information of the property acquired by the registration information acquisition unit 24, for example. Here, for example, the owner identification unit 26 identifies the latest owner of the property of interest indicated in the registration information data of interest, which is the registration information of the property. However, if the acquisition date and time of the registration information data of interest is old, the latest owner of the property of interest indicated in the registration information data of interest is not necessarily the current owner of the property of interest.

[0047] Here, we will explain an example of the process for identifying the latest owner of the real estate, as indicated in the registration information data obtained at 9:12 AM on April 1, 2018, based on the rights section (Section A) data included in the real estate registration information data shown in Figure 2B, referring to the flowchart illustrated in Figure 5.

[0048] First, the owner identification unit 26 generates initial owner management data, as illustrated in Figure 6A (S101). Owner management data is data associated with real estate. As shown in Figure 6A, the owner management data includes, for example, owner name data indicating the name (e.g., full name) of the owner of the real estate associated with the owner management data, owner address data indicating the address of the owner of the real estate, and ownership share data indicating the owner's share of the real estate. Initially, the value of the owner name data is "unknown", the value of the owner address data is "unknown", and the value of the ownership share data is 100%.

[0049] Then, the owner identification unit 26 sets the value of variable N to 1 (S102). The owner identification unit 26 then checks whether the value of the registration purpose data included in the Section A element data whose rank number is N contains the string "transfer" (S103).

[0050] If it is not included (S103:N), the process proceeds to S105. If it is included (S103:Y), the owner identification unit 26 updates the owner management data based on the value of the registration purpose data and the rights holder and other matters data included in the Section A element data with priority number N (S104). A specific example of the process shown in S104 will be described later.

[0051] Then, the owner identification unit 26 checks whether N is the last rank number (S105). If N is not the last rank number (S105:N), the owner identification unit 26 increments the value of N by 1 (S106) and proceeds to the process shown in S103.

[0052] If N is the last rank number (S105:Y), the process shown in this example is terminated.

[0053] In the process shown in S104, for example, named entity recognition (NER) technology is used to check whether the value of the registration purpose data contains a string indicating a name or other designation.

[0054] If it is confirmed that the value of the registration purpose data does not contain a string indicating a name or other designation, then named entity recognition technology is used to extract a string indicating an address and a string indicating a name (e.g., name) from the rights holder and other matters data according to predetermined rules. For example, a combination of a string indicating an address and a string indicating a name following the string "owner" may be extracted. Alternatively, one or more combinations of a string indicating an address, a string indicating a share, and a string indicating a name following the string "co-owner" may be extracted.

[0055] Then, the owner management data for which the owner name data value is "unknown" is updated.

[0056] For example, in the rights section (Section A) data shown in Figure 2B, based on the Section A element data with rank number 1, the combination of the owner's address "B City, C Town, D124-1" and the owner's name "Mr. N" is extracted from the rights holder and other matters data. Based on this, the owner management data is updated from what is shown in Figure 6A to what is shown in Figure 6B. That is, the rights holder management data where the value of the owner name data is "unknown", the value of the owner address data is "unknown", and the ownership share data is "100%" is updated to the rights holder management data where the value of the owner name data is "Mr. N", the value of the owner address data is "A Prefecture, B City, C Town, D124-1", and the ownership share data is "100%". In this way, the value of the owner address data may be set to a string in which a predetermined string "A Prefecture" is added before the owner's address extracted from the rights holder and other matters data.

[0057] Furthermore, based on the Section A element data with rank number 2, the combination of the owner's address "B City C Town D125-2", ownership share "1 / 2", and owner's name "M. O. O." is extracted from the rights holder and other matters data, as well as the combination of the owner's address "B City C Town D125-3", ownership share "1 / 2", and owner's name "M. P. K.".

[0058] Based on this, the owner management data is updated from what is shown in Figure 6B to what is shown in Figure 6C. Specifically, the rights holder management data where the owner name data value is "Mr. N," the owner address data value is "D124-1, C-cho, B-city, A-prefecture," and the ownership share data is "100%" is updated to the rights holder management data where the owner name data value is "Mr. O," the owner address data value is "D125-2, C-cho, B-city, A-prefecture," and the ownership share data is "50%", and the rights holder management data where the owner name data value is "Mr. P," the owner address data value is "D125-3, C-cho, B-city, A-prefecture," and the ownership share data is "50%".

[0059] If it is confirmed that the value of the registration purpose data includes a string indicating a name or other designation, the same process as described above will be used to extract the string indicating the address and the string indicating the name from the rights holder and other matters data using named entity recognition technology.

[0060] In this case, the owner management data is updated, and the name or other designation confirmed in the registration purpose data is set as the value of the owner name data.

[0061] For example, based on the Section A element data with rank number 3, "M. O

[0062] Based on this, the owner management data is updated from what is shown in Figure 6C to what is shown in Figure 6D. Specifically, the owner name data value is "Mr. O.", the owner address data value is "D125-2, C-cho, B-city, A-prefecture", and the ownership share data is "50%", and the owner management data is updated to "R. Taro Qgawa", the owner address data value is "G24-1, F-cho, E-city, A-prefecture", and the ownership share data is "50%".

[0063] As described above, based on the rights section (Section A) data shown in Figure 2B, it is ultimately determined that the most recent owners shown in the registration information data are "Qgawa R Taro" and "Mida P Ko".

[0064] Furthermore, the process for identifying the most recent owner is not limited to the methods described above. For example, if there is only one Section A element data in the rights section (Section A) data, the owner identification unit 26 may identify the address following the string "owner" in the rights holder and other matters data of the Section A element data as the address of the most recent owner, and identify the name following the string representing that address as the name of the most recent owner.

[0065] In this embodiment, the inheritance occurrence estimation unit 28 determines, for example, whether there exists a first registration application information among the multiple registration application information stored in the registration application information storage unit 22, which is registration application information relating to the property of interest, where the acceptance date is after the acquisition date of the registration information acquired by the registration information acquisition unit 24, and the purpose of the registration is indicated to be the transfer of ownership through inheritance.

[0066] Furthermore, if the inheritance occurrence estimation unit 28 determines that a first registration application information exists, it determines whether there exists a second registration application information among the multiple registration application information stored in the registration application information storage unit 22, which is registration application information pertaining to the property of interest, whose acceptance date is after the date of acquisition of the registration information obtained by the registration information acquisition unit 24 and before the acceptance date of the first registration application information, and whose purpose of registration is indicated to be the transfer of ownership. In this embodiment, registration application information in which the purpose of registration is indicated to be the transfer of ownership is also considered to be registration application information in which the purpose of registration is indicated to be the transfer of ownership. That is, if the value of the purpose of registration data of the registration application information data pertaining to the property of interest contains the string "transfer of ownership", and whose acceptance date is after the date of acquisition of the registration information obtained by the registration information acquisition unit 24 and before the acceptance date of the first registration application information, then said registration application information data corresponds to the second registration application information.

[0067] Then, the inheritance occurrence estimation unit 28 determines that there is a first registration application information and that there is no second registration application information, and presumes that the property of interest is the property that was inherited with the owner identified by the owner identification unit 26 as the deceased.

[0068] For example, let's assume that the registration information data shown in Figures 2A and 2B are the registration information data of interest. In this case, based on the registration information data of interest, the string "A Prefecture B City C Town D123-1", which is formed by combining the predetermined string "A Prefecture", the location data value "B City C Town D", and the land number data value "123-1", is identified as the land number of the property of interest that is associated with the registration information data of interest.

[0069] Then, from among the multiple registration application information data stored in the registration application information storage unit 22, the string formed by combining the values ​​of prefecture name data, city / ward / town / village name data, district name data, and land number / house number data is identified as "A Prefecture B City C Town D123-1", and the value of the use data is "land". Hereinafter, each of the one or more registration application information data identified in this way will be referred to as the registration application information data of interest.

[0070] Then, it is checked whether there is one or more of the target registration application information data where the date indicated by the acceptance date data is after the date indicated by the acquisition date data of the target registration information data, and the value of the registration purpose data is "transfer of ownership inheritance". If this is confirmed, the target registration application information data will be considered to be the first registration application information.

[0071] Furthermore, if the existence of the first registration application information is confirmed, it is checked whether there is one or more of the target registration application information data where the date indicated by the acceptance date data is after the date indicated by the acquisition date data of the target registration information data, but before the date indicated by the acceptance date data of the target registration application information data that is the first registration application information, and the string indicated by the registration purpose data contains "transfer of ownership". If confirmed, that target registration application information data will be considered to be the second registration application information.

[0072] For example, in the registration information data shown in Figures 2A and 2B, the date indicated by the acquisition date data is April 1, 2018.

[0073] In this case, it is confirmed that the registration application information data shown in Figure 3 is stored in the registration application information storage unit 22. The date indicated by the receipt date data of the said registration application information data is September 22, 2023, and the value of the registration purpose data is "Transfer of ownership, inheritance". Therefore, in this case, it is determined that the first registration application information exists.

[0074] Furthermore, in this case, it is confirmed that the registration application information data shown in Figure 4 is stored in the registration application information storage unit 22. The date indicated by the receipt date data of the said registration application information data is January 20, 2020, and the value of the registration purpose data is "Transfer of Ownership". Therefore, in this case, it is determined that the second registration application information exists.

[0075] Thus, if the registration application information storage unit 22 stores both the registration application information data shown in Figure 3 and the registration application information data shown in Figure 4, the property of interest (land in this example) is not presumed to be the property subject to inheritance, with the owner identified by the owner identification unit 26 being the deceased.

[0076] On the other hand, if the registration application information data shown in Figure 3 is stored in the registration application information storage unit 22, but the registration application information data shown in Figure 4 is not stored, then the property of interest (land in this example) is presumed to be property that has been inherited, with the owner identified by the owner identification unit 26 being the deceased.

[0077] Furthermore, as shown in Figure 6D, if there are multiple owners identified by the owner identification unit 26, the inheritance occurrence estimation unit 28 estimates that one of these multiple owners is the deceased of the property of interest.

[0078] As described above, according to this embodiment, by utilizing registration application information, it becomes possible to accurately estimate whether the real estate indicated in the registration information is subject to inheritance with the most recent owner of the real estate indicated in the registration information as the deceased, even if the registration information is prior to the inheritance registration.

[0079] In the above example, the property of interest was land, but even if the property of interest is a building or a subdivided building, it is possible to estimate whether or not the property of interest was subject to inheritance with the owner identified in the owner identification section 26 as the deceased, using the same method.

[0080] In this embodiment, the association unit 30 associates, for example, the first registration application information with the real estate registration information related to the first registration application information, which is obtained after the date of receipt of the first registration application information.

[0081] For example, from among the multiple registration information data stored in the registration information storage unit 20, a registration information data containing Section A element data that includes the same date as the date indicated by the date of receipt data included in the registration application information data which is the first registration application information, and the same receipt number as the receipt number included in the registration application information data which is the first registration application information, may be identified. The association unit 30 may then associate the registration information data identified in this way with the registration application information data which is the first registration application information.

[0082] By doing so, it becomes possible to identify the heirs, the deceased, the date of death, etc., of the real estate that is the subject of the registration application related to the first registration application information.

[0083] However, the present invention is not limited to the embodiments described above.
