Mode for Carrying Out the Invention

[0014] Hereinafter, an embodiment of the present invention will be described in detail based on the drawings.

[0015] FIG. 1 is a functional block diagram showing an example of functions implemented in the owner same real estate display control system 10 according to the present embodiment. Note that in the owner same real estate display control system 10 according to the present embodiment, it is not necessary to implement all the functions shown in FIG. 1, and functions other than those shown in FIG. 1 may be implemented.

[0016] As shown in FIG. 1, the owner same real estate display control system 10 according to the present embodiment functionally includes, for example, a registration information storage unit 20, a map image storage unit 22, an owner identification unit 24, a registration information acquisition unit​​​The owner identical real estate display control system 10 may be constituted by a known computer including, for example, a CPU, a memory, a communication interface, an input device, and a display. And, the functional blocks shown in FIG. 1 are realized by executing an owner identical real estate display control program in the owner identical real estate display control system 10 which is a computer. The owner identical real estate display control program may be stored in various computer-readable information storage media such as a semiconductor memory, and may be loaded from the medium into the owner identical real estate display control system 10. Alternatively, it may be downloaded to the owner identical real estate display control system 10 via a data communication line such as the Internet.

[0018] In this embodiment, the registration information storage unit 20 stores, for example, a plurality of real estate registration information. For example, data of real estate registration information may be acquired in advance from a registration information providing service by an entity such as the General Incorporated Association of Civil Law Affairs via a communication interface. And, the registration information data which is the acquired data of real estate registration information may be stored in the registration information storage unit 20.

[0019] FIG. 2A and FIG. 2B are diagrams showing an example of registration information data. It is assumed that one registration information data is represented by the entirety of FIG. 2A and FIG. 2B.

[0020] The registration information data according to this embodiment is associated with information on all matters of real estate registration for one piece of real estate. In FIG. 2A and FIG. 2B, registration information data associated with information on all matters of real estate registration of land is shown. As shown in FIG. 2A and FIG. 2B, the registration information data according to this embodiment includes prefecture name data, title section data, and right section (section A) data. In the registration information data, erased values are underlined.

[0021] The prefecture name data shown in FIG. 2A is data indicating the prefecture name where the real estate associated with the registration information data is located.

[0022] <The title section data shown in Figure 2A corresponds to the content of the title section of the corresponding real estate registration. The title section data includes display type data, preparation date data, real estate number data, map number data, boundary identification data, and location data.

[0023] The display type data is the data indicating the type of real estate, written in parentheses to the right of the title section of the complete real estate registration. The preparation date data, real estate number data, map number data, boundary identification data, and location data are data that indicate the contents of the preparation, real estate number, map number, boundary identification, and location sections of the complete real estate registration, respectively.

[0024] Furthermore, the registration information data associated with the complete real estate registration information for a building includes location map number data, which indicates the location map number described in the title section of the complete real estate registration, instead of map number data.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] In this embodiment, the map image storage unit 22 stores a map image in which each pixel is associated with a geographical location (e.g., latitude and longitude).

[0032] In this embodiment, the owner identification unit 24 identifies, for example, the most recent owner of the real estate associated with a given set of real estate registration information (for example, a set of real estate registration information stored in the registration information storage unit 20), as indicated in the real estate registration information. Here, for example, the owner identification unit 24 identifies, based on the registration information data, the most recent owner of the real estate associated with the registration information data, as indicated in the registration information data.

[0033] The owner identification unit 24 then associates owner data indicating the owner identified based on the registration information data with the said registration information data. The owner data may include, for example, owner name data indicating the name of the identified owner (e.g., full name) and owner address data indicating the address of the identified owner.

[0034] In this embodiment, for example, owner data is associated with all of the multiple registration information data stored in the registration information storage unit 20. Here, as an example, we will explain an example of a process flow in which, based on the rights section (Section A) data included in the real estate registration information data shown in Figure 2B, the latest owner of the real estate indicated in the registration information data is identified, and owner data indicating that owner is associated with the registration information data, referring to the flowchart illustrated in Figure 3. Hereinafter, the registration information data to which owner data is associated will be referred to as owner-associated registration information data.

[0035] First, the owner identification unit 24 generates initial owner management data, as illustrated in Figure 4A (S101). Owner management data is data associated with real estate. As shown in Figure 4A, 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%.

[0036] Then, the owner identification unit 24 sets the value of variable N to 1 (S102). The owner identification unit 24 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).

[0037] If it is not included (S103:N), the process proceeds to S105. If it is included (S103:Y), the owner identification unit 24 updates the owner management data based on the value of the registration purpose data included in the Class A element data with rank number N, and the rights holder and other matters data, which are included in the owner-associated registration information data (S104). A specific example of the process shown in S104 will be described later.

[0038] Then, the owner identification unit 24 checks whether N is the last rank number (S105). If N is not the last rank number (S105:N), the owner identification unit 24 increments the value of N by 1 (S106) and proceeds to the process shown in S103.

[0039] If N is the last rank number (S105:Y), the owner identification unit 24 identifies the latest owner of the real estate associated with the owner-associated registration information data, as shown in the owner-associated registration information data, based on the latest owner management data (S107). A specific example of the process shown in S107 will be described later.

[0040] Then, the owner identification unit 24 generates owner data indicating the owner identified in the process shown in S107, associates the generated owner data with the owner-associated registration information data (S108), and the process shown in this example is completed.

[0041] In the process shown in S104, for example, named entity recognition (NER) technology is used to determine the registration details. The system checks whether the target data value contains a string indicating a name or other identifier.

[0042] Here, it is confirmed that the value of the registration purpose data does not contain a string indicating a name or other designation. If this occurs, the rights holder will be identified using named entity recognition technology, etc., in accordance with predetermined rules. A string representing the address and a string representing the name (e.g., full name) are extracted from other data. Here, for example, the string "owner" is followed by a "string indicating the address" and "name". A combination of strings indicating " may be extracted. Also, the string "shared by" followed by The combination of "a string indicating the address," "a string indicating the share," and "a string indicating the name" is 1 Alternatively, multiple results may be extracted.

[0043] Then, the owner management data for which the owner name data value is "unknown" is updated.

[0044] For example, in the rights section (Section A) data shown in Figure 2B, the Section A element data has a rank number of 1. Based on this, the combination of the owner's address "D124-1, C-cho, B-city, A-prefecture" and the owner's name "Mr. N. Tadashi" is extracted from the rights holder and other information data. Then, based on this, the owner management data is updated from what is shown in Figure 4A to what is shown in Figure 4B. That is, the rights holder management data where the owner name data value is "unknown", the owner address data value is "unknown", and the ownership share data is "100%" is updated to the rights holder management data where the owner name data value is "Mr. N. Tadashi", the owner address data value is "D124-1, C-cho, B-city, A-prefecture", and the ownership share data is "100%".

[0045] Furthermore, based on the Section A element data with rank number 2, the combination of the owner's address "A Prefecture 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 "A Prefecture B City C Town D125-3", ownership share "1 / 2", and owner's name "M. P. K.".

[0046] Based on this, the owner management data is updated from what is shown in Figure 4B to what is shown in Figure 4C. Specifically, 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 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 to 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%."

[0047] 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.

[0048] In this case, the name or other designation confirmed in the registration purpose data is the owner's name. The owner management data, which is set as the data value, will be updated.

[0049] For example, based on the Section A element data with rank number 3, "M. O

[0050] Based on this, the owner management data is updated from what is shown in Figure 4C to what is shown in Figure 4D. That is, 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%" is updated to the rights holder management data where the owner name data value is "R. Taro Qgawa", the owner address data value is "H24-1, G-cho, F-city, E-prefecture", and the ownership share data is "50%". In this example, the owner management data shown in Figure 4D becomes the owner management data used in the process shown in S107.

[0051] In the process shown in S107, based on the owner management data shown in Figure 4D, it is identified that there are two current owners as indicated in the owner-associated registration information data. The name and address of one owner are identified as "Qgawa R Taro" and "H24-1, G-cho, F-shi, E-ken," and the name and address of the other owner are identified as "Mida P-ko" and "D25-3, C-cho, B-shi, A-ken." Thus, the owner identification unit 24 may identify multiple owners for jointly owned real estate.

[0052] Thus, if it is determined that there are multiple current owners, the process shown in S108 will associate multiple owner data with the owner-associated registration information data. For example, if it is determined that there are two current owners, the process shown in S108 will associate two owner data with the owner-associated registration information data. In the example above, owner data containing owner name data with the value "Qgawa R Taro" and owner address data with the value "E Prefecture F City G Town H24 No. 1", and owner data containing owner name data with the value "Mda P Ko" and owner address data with the value "A Prefecture B City C Town D25 No. 3", will be associated with the owner-associated registration information data. If it is determined that there is only one current owner, the process shown in S108 will associate one owner data with the owner-associated registration information data. Furthermore, if it is determined that there are n current owners (n is an integer greater than or equal to 3), the process shown in S108 will associate n owner data with the owner-associated registration information data.

[0053] 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 24 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. The owner data, which includes owner name data indicating the name of the owner identified in this way and owner address data indicating the address of the owner identified in this way, may be associated with the owner-associated registration information data.

[0054] In this embodiment, the registration information acquisition unit 26 acquires, for example, one of several pieces of registration information, which is the registration information of interest. The registration information acquisition unit 26 acquires, for example, any one of several pieces of registration information data stored in the registration information storage unit 20 as the registration information of interest data. For example, the registration information data that can be associated with a property that the user wishes to identify as having the same most recent owner may be acquired as the registration information of interest data.

[0055] In this embodiment, the Owner Identical Registration Information Identification Unit 28 identifies, for example, from among multiple real estate registration information stored in the Registration Information Storage Unit 20, the real estate registration information in which the identified owner is a given owner of interest as Owner Identical Registration Information. In the following description, it will be assumed that multiple Owner Identical Registration Information are identified.

[0056] Here, the Owner Identical Registration Information Identification Unit 28 may identify the most recent owner of the property associated with the Registration Information Data of Interest, as identified by the Owner Identification Unit 24, as the Owner of Interest. For example, the name indicated by the owner name data included in the owner data associated with the Registration Information Data of Interest may be identified as the name of the Owner of Interest. Alternatively, the address indicated by the owner address data included in the owner data may be identified as the address of the Owner of Interest. If there are multiple most recent owners of the property associated with the Registration Information Data of Interest, the Owner Identical Registration Information Identification Unit 28 may identify any one of those multiple owners (for example, one owner designated by the user from among those multiple owners) as the Owner of Interest. The Owner Identical Registration Information Identification Unit 28 may then identify multiple registration information data where the most recent owner is the Owner of Interest as Owner Identical Registration Information Data. Here, the Registration Information Data of Interest may be identified as Owner Identical Registration Information Data.

[0057] Here, the Owner Identical Registration Information Identification Unit 28 may identify, with respect to jointly owned real estate, real estate registration information in which the owner of interest is included among the multiple identified owners as Owner Identical Registration Information. For example, the Owner Identical Registration Information Identification Unit 28 may identify, among the multiple registration information data stored in the registration information storage unit 20, those in which the associated owner data includes owner data indicating the owner of interest as Owner Identical Registration Information Data. For example, registration information data in which the associated owner data includes owner name data indicating the name of the owner of interest and owner address data indicating the address of the owner of interest may be identified as Owner Identical Registration Information Data.

[0058] In this embodiment, the map display control unit 30 displays a map showing the locations corresponding to the real estate indicated by each of the multiple identical owner registration records identified.

[0059] The map display control unit 30 may, for example, generate a string for each piece of owner-identified registration information data by combining the string indicated by the prefecture name data and the string indicated by the location data included in the owner-identified registration information data.

[0060] Furthermore, the map display control unit 30 may, for example, access a geographic information service that provides a geocoding function that converts strings representing addresses, place names, etc., with geographic locations (e.g., latitude and longitude) via various application programming interfaces (APIs) to identify the geographic location (e.g., latitude and longitude) corresponding to the location represented by the generated string.

[0061] The map display control unit 30 may then generate the display target image 40, as illustrated in Figures 5 and 6, based on the geographical location specified for each of the multiple identical owner registration records as described above, and the map image stored in the map image storage unit 22. The map display control unit 30 may then display the generated display target image 40 on the display.

[0062] Furthermore, the map display control unit 30 may access the aforementioned geographic information provision service to identify the geographic location (e.g., latitude and longitude) corresponding to the address of the most recent owner identified in the registration information data of interest.

[0063] The map display control unit 30 may then generate a display target image 40 based on the geographic location identified in this manner. The map display control unit 30 may then display the generated display target image 40 on the display.

[0064] Furthermore, if the real estate associated with the same-owner registration information is jointly owned real estate, the map display control unit 30 may display a map showing the locations corresponding to the addresses of multiple owners of the real estate, including the owner of interest, and the location corresponding to the location of the real estate as indicated in the same-owner registration information.

[0065] In this embodiment, for example, a display target image 40 is generated that shows a given geographical area (for example, a geographical area specified by the user), which is a part of the geographical area shown by the map image.

[0066] Figure 5 shows an example of the display target image 40 shown on the display. The display target image 40 shown in Figure 5 shows the owner of interest image 42, owned property images 44a (44a to 44d), and arrow images 46 (46a to 46e) superimposed on the map image.

[0067] The map display control unit 30 identifies, for example, a pixel in the map image associated with the geographical location corresponding to the address of the most recent owner identified in the registration information data of interest. The map display control unit 30 then positions the owner image 42 of interest such that the center pixel of the owner image 42 is positioned at the location of the identified pixel.

[0068] Furthermore, the map display control unit 30 identifies, for example, a pixel in the map image associated with the geographical location identified as described above for each of the multiple identical owner registration records.

[0069] Then, if the identified geographical location is included in the geographical range indicated by the display target image 40, the map display control unit 30 positions the owned property image 44 such that the center pixel of the owned property image 44 is positioned at the location of the identified pixel. The map display control unit 30 then positions, for example, an arrow image 46 pointing from a location corresponding to the address of the owner of interest to a location corresponding to the location of the property indicated in the owner-identified registration information.

[0070] On the other hand, if the identified geographic location is not included in the geographic range indicated by the display target image 40, the map display control unit 30 places an arrow image 46 that extends from the center pixel of the owner of interest image 42 to the edge of the display target image 40, superimposed on a line that extends from the center pixel of the owner of interest image 42 to a pixel in the map image associated with that geographic location.

[0071] In the example shown in Figure 5, five identical owner registration data sets are identified. One of these five identical owner registration data sets is located at a geographical location not included in the geographical range indicated by the display target image 40. Hereafter, this identified geographical location for the identical owner registration data set will be referred to as the location outside the display target image. Of the remaining four identical owner registration data sets, two are land registration data sets and two are building registration data sets. In this case, the geographical location identified for the building registration data set is represented by the property images 44 (44a and 44b) indicating the building, and the geographical location identified for the land registration data set is represented by the property images 44 (44c and 44d) indicating the land.

[0072] In the example shown in Figure 5, arrow images 46a point from the central pixel of the owner image 42 to the central pixel of the property image 44a, arrow images 46b point from the central pixel of the owner image 42 to the central pixel of the property image 44b, arrow images 46c point from the central pixel of the owner image 42 to the central pixel of the property image 44c, and arrow images 46d point from the central pixel of the owner image 42 to the central pixel of the property image 44d. In addition, in the example shown in Figure 5, an arrow image 46e is also placed that superimposes on the line from the central pixel of the owner image 42 to the pixel in the map image associated with the above-mentioned location outside the display target image, and points from the central pixel of the owner image 42 to the edge of the display target image 40.

[0073] Thus, the map display control unit 30 may display a map showing an arrow pointing from a location corresponding to the address of the owner of interest to a location corresponding to the location of the real estate indicated in the owner-identified registration information.

[0074] Figure 6 shows another example of the display target image 40 shown on the display. The display target image 40 shown in Figure 6 includes an image of the owner of interest 42, images of owned properties 44a (44a to 44d), arrow images 46 (46a to 46g), and co-owner images 48 (48a and 48b) superimposed on the map image.

[0075] In the example in Figure 6, unlike the example in Figure 5, the property associated with property image 44a and the property associated with property image 44d are assumed to be jointly owned by two owners. Furthermore, the owner of the property associated with property image 44a is different from the owner of interest, and the owner of the property associated with property image 44d is different from the owner of interest.

[0076] If the real estate associated with the same owner registration information is jointly owned real estate, the map display control unit 30 identifies a pixel in the map image associated with the geographical location corresponding to the address of the most recent owner of the real estate other than the owner of interest. The map display control unit 30 then positions the co-owner image 48 such that the center pixel of the co-owner image 48 is positioned at the location of the identified pixel. For example, for real estate associated with the owned real estate image 44a, the co-owner image 48a is positioned, and for real estate associated with the owned real estate image 44d, the co-owner image 48b is positioned.

[0077] In this case, the map display control unit 30 also places an arrow image 46 that points from a location corresponding to the address of an owner other than the owner of interest to a location corresponding to the location of the real estate shown in the owner-identified registration information. In the example of Figure 6, an arrow image 46f is placed that points from the center pixel of the co-owner image 48a to the center pixel of the owned real estate image 44a, and an arrow image 46g is placed that points from the center pixel of the co-owner image 48b to the center pixel of the owned real estate image 44d. Other processing performed with respect to Figure 6 is the same as the processing described with reference to Figure 5, so its explanation is omitted.

[0078] As described above, this embodiment makes it easy to identify multiple properties that have the same most recent owner.

[0079] However, the present invention is not limited to the embodiments described above.

[0080] For example, the owner-identified real estate display control system 10 may accept input from the user of a string indicating the name and address of the owner of interest. Then, the registration information data associated with the owner data, which includes owner name data indicating the name and owner address data indicating the address, may be identified as owner-identified registration information data.

[0081] Furthermore, the specific strings and numbers mentioned above, as well as the specific strings and numbers in the drawings, are examples only and are not limited to these strings and numbers. [Explanation of Symbols]
