(Embodiment)
1 is an explanatory diagram showing an example of the configuration of a property search system. In this embodiment, a property search system is described that generates a database for property search (search DB 142 described later) by associating property information extracted from real estate registration data (hereinafter referred to as "first property information") with property information based on data other than real estate registration data (hereinafter referred to as "second property information"), and searches and outputs property information from the database in response to a request received from a user. The property search system includes an information processing device 1, terminals 2, 2, 2, . . . Each device is communicatively connected via a network N such as the Internet.

The information processing device 1 is an information processing device capable of various information processing and information transmission and reception, such as a server computer, a personal computer, etc. In this embodiment, the information processing device 1 is a server computer, and will be referred to as server 1 below for simplicity. In this embodiment, the server 1 provides a property search service that allows parties involved in real estate property transactions to search for information on income properties that are candidates for purchase. As will be described in detail later, the server 1 extracts first property information related to real estate properties from real estate registration data (e.g., real estate registry PDF (Portable Document Format) data), and generates a database for property search by associating the extracted first property information with second property information stored in a database (second property information DB 141 described later) constructed based on data other than the real estate registration data. The server 1 then searches for and outputs property information from the database in response to a request received from a user.

The terminal 2 is a terminal device used by a user of the system, such as a personal computer, a smartphone, or a tablet terminal. The server 1 accepts requests from users via the terminal 2 and searches for property information.

2 is a block diagram showing an example of the configuration of the server 1. The server 1 includes a control unit 11, a main memory unit 12, a communication unit 13, and an auxiliary memory unit .
The control unit 11 has one or more arithmetic processing devices such as a central processing unit (CPU), a micro-processing unit (MPU), a graphics processing unit (GPU), etc., and performs various information processing, control processing, etc. by reading and executing a program P1 stored in the auxiliary storage unit 14. The main storage unit 12 is a temporary storage area such as a static random access memory (SRAM) or a dynamic random access memory (DRAM), and temporarily stores data necessary for the control unit 11 to execute arithmetic processing. The communication unit 13 is a communication module for performing processing related to communication, and transmits and receives information to and from the outside.

The auxiliary storage unit 14 is a non-volatile storage area such as a large-capacity memory or a hard disk, and stores the program P1 (program product) and other data necessary for the control unit 11 to execute processing. The auxiliary storage unit 14 also stores a second property information DB 141, a search DB 142, and an update history DB 143. The second property information DB 141 is a database that stores second property information constructed based on data other than real estate registration data. The search DB 142 is a database that stores first property information extracted from real estate registration data in association with second property information. The update history DB 143 is a database that stores the update history (change history) of the name or address of the property owner.

The auxiliary storage unit 14 may be an external storage device connected to the server 1. The server 1 may be a multi-computer consisting of multiple computers, or may be a virtual machine virtually constructed by software.

In the present embodiment, the server 1 is not limited to the above configuration, and may include, for example, an input unit that accepts operational input, a display unit that displays images, etc. The server 1 may also include a reading unit that reads portable storage medium 1a such as a CD (Compact Disk)-ROM or a DVD (Digital Versatile Disc)-ROM, and may read and execute the program P1 from the portable storage medium 1a.

FIG. 3 is an explanatory diagram showing an example of the record layout of the second property information DB 141, the search DB 142, and the update history DB 143.
The second property information DB 141 includes a property ID column, a name column, an address column, and a second property information column. The property ID column stores a property ID for identifying each real estate property (building). The name column, the address column, and the second property information column store the name and address of a property, and second property information related to the property, in association with the property ID, respectively.

Search DB142 includes a property ID column, a parcel number column, a holding period column, an owner ID column, an owner name column, an owner address column, a property name column, a property address column, and a property information column. The property ID column stores a property ID for identifying each real estate property. The parcel number column, holding period column, owner ID column, owner name column, owner address column, property name column, property address column, and property information column each store, in correspondence with the property ID, the property parcel number, the holding period of the property by the owner, the owner ID for identifying the property owner, the owner name, the owner address, the property name, the property address, and property information (first property information and second property information).

Update history DB143 includes an update date column, a new name column, a new address column, an old name column, and an old address column. The update date column stores the update date of the property's name or address (the date when the name change or address change was registered). The new name column, new address column, old name column, and old address column store the latest property name, address, old property name, and old address, respectively, in association with the update date.

Figures 4 to 10 are explanatory diagrams showing examples of the display screen of terminal 2. The following provides an overview of this embodiment.

As described above, the server 1 generates a search DB 142 (second database) by associating the first property information extracted from the real estate registration data with the second property information stored in the second property information DB 141 (first database). The server 1 then searches for and outputs property information from the search DB 142 in response to a request received from a user.

The real estate registration data is, for example, PDF data of a real estate registry. Server 1 acquires (collects) real estate registration data for a large number of real estate properties using a registration information service (a service that provides registration information held by a registry office via the Internet) or the like, and extracts first property information for each real estate property from the acquired real estate registration data.

In this embodiment, the server 1 is described as automatically extracting the first property information from the real estate registration data, but the embodiment is not limited to this, and the first property information may be read manually and input to the server 1.

The first property information includes first property identification information capable of identifying a real estate property, and real estate registration specific information. The first property identification information is, for example, but is not limited to, the property's lot number. The real estate registration specific information is information recorded in the real estate registry, and includes, for example, security interest establishment information, ownership transfer history information, information regarding the property's land area or structure, registration information regarding disposal restrictions, and trust information.

The second property information DB141 is a database constructed from data other than real estate registration data, and stores second property information that differs in part or in whole from the first property information.

In this embodiment, the second property information DB141 (first database) is described as being constructed from data other than real estate registration data, but it is not essential that the second property information DB141 be constructed from data other than real estate registration data, and it may be constructed including real estate registration data. In other words, the second property information DB141 (first database) is mainly composed of data other than real estate registration data, such as tenant-related information, and as long as it has data to construct a search DB142 (second database) that associates with real estate registration data and stores property information including real estate registration-specific information and tenant-related information, it does not exclude those that contain even a small amount of real estate registration data.

The second property information DB141 may be stored in a server computer other than Server 1 among multiple server computers managed by the administrator of this system. Alternatively, the second property information may be provided by a third party other than the administrator of this system and stored as the second property information DB141.

The second property information includes second property identification information capable of identifying the real estate property, and resident-related information. The second property identification information is, for example, but is not limited to, the address of the property. The resident-related information is information relating to the occupants of the property and the occupancy conditions, and includes, for example, the conditions for soliciting occupancy (such as the offered rent), occupant history information, and information relating to vacancies (such as the vacancy rate).

The server 1 generates a search DB 142 that stores property information including real estate registration specific information and tenant-related information by associating the first property information and the second property information based on the first property identification information and the second property identification information.

Specifically, when server 1 acquires (collects) real estate registration data, server 1 reads out the address (second property specific information) of each real estate property from second property information DB 141. Based on the read address, server 1 identifies the location of the property on a map using a map search engine (such as Google Map (registered trademark)). Server 1 then acquires the land number (first property specific information) of the same location using a land number search service that can be accessed using a registration information providing service or the like. Based on the acquired land number, server 1 acquires real estate registration data using the registration information providing service or the like, and extracts the first property information.

Then, the server 1 associates the first property information with the second property information based on the correspondence between the land number searched for using the map search engine and the address used as the search query. This links the property indicated by the real estate registration data with the property for which the second property information is stored in the second property information DB 141.

When performing a map search based on an address as described above, it may not be possible to identify the land number from the map, and multiple land numbers (properties) may be linked. In this case, it is preferable for the server 1 to select the optimal land number by determining the degree of agreement between the basic property information (e.g., the number of floors of the building, floor area, etc.) included in the first property information and the second property information.

As described above, the server 1 generates the search DB 142. After generating the search DB 142, the server 1 receives a request from a user to search for property information, searches for property information from the search DB 142 in response to the request, and outputs the property information to the terminal 2.

In this embodiment, it is possible to perform a search based on the property and a search based on the owner of the property. Figure 4 is an explanatory diagram showing an example of a property search screen. Figure 4 shows an example of a search screen based on the property.

The property search screen includes a property search field 41. The property search field 41 is an input field for narrowing down properties using the first property information or the second property information as search criteria. For example, the terminal 2 accepts input of the property name (building name) to be searched for, the area in which the property is located, the year of completion, the total floor area, etc. via the property search field 41. The server 1 searches the search DB 142 for properties that meet the search criteria.

The server 1 outputs various data related to the searched properties from the search DB 142. For example, the server 1 calculates and outputs the total floor area of the property based on the real estate registration specific information. The server 1 also calculates and outputs the vacancy rate of the property based on the tenant-related information. Furthermore, if a property is owned by multiple owners, the server 1 calculates and outputs the ownership percentage of each owner in the entire property based on the real estate registration specific information. In addition, the server 1 extracts and outputs the year of completion of the property, etc. from the real estate registration specific information and/or the tenant-related information.

In this embodiment, the "vacancy rate" may include not only the current vacancy rate, but also the potential vacancy rate (rooms that have not been renewed are calculated as vacant rooms) that takes into account future vacancies based on the contract status. The current vacancy rate is calculated, for example, by calculating the available rent area of the total floor area and dividing the area of vacant rooms available for rent by the available rent area. The potential vacancy rate is calculated by dividing the sum of the area of vacant rooms available for rent and the area of vacant rooms that have not been renewed by the available rent area.

In addition, if the server 1 already has information on the total floor area of several properties as the second property information, it may simply acquire the total floor area of the missing properties from the real estate registration data (real estate registration specific information). In addition, the total floor area may be calculated as an estimated area, for example, by multiplying the standard floor area by the number of floors.

When calculating the ownership ratio of each owner, the server 1 calculates, for example, the total floor area for each section owned by each owner, and calculates the ratio of the total floor area of each section to calculate the ownership ratio.

Furthermore, the server 1 may output an alert to the user when the number of owners of a property reaches or exceeds a threshold value (e.g., two owners). This can notify the user that the property will require a high negotiation burden when acquiring it.

Terminal 2 displays a list of the property information output from server 1 on a property search screen. For example, terminal 2 displays the year of completion of the property, total floor area, vacancy rate, and current property owner information (owner name and ownership percentage) in association with each property name.

FIGS. 5 to 7 are explanatory diagrams showing examples of property details screens. When an operation input to select any property is received on the property search screen of FIG. 4, terminal 2 displays the property details screens shown in FIG. 5 to FIG. 7.

For example, terminal 2 displays basic information about the property (property name, address, nearest station, etc.) as well as a button 51 for switching the display screen. When an operation input is received through the "Owner Information" button 51, terminal 2 displays the screen shown in FIG. 5. In this case, terminal 2 displays information about the current property owner (owner name, ownership percentage, start date of ownership, etc.), as well as owner transfer history information.

For example, server 1 may acquire information about the property owner (company) in advance (such as stock price, address, and group company information), and output information about the property owner when it receives an operation input (click) on the property owner's name on the property details screen.

When an operation input to the "Performance" button 51 is received, the terminal 2 displays the screen shown in FIG. 6. In this case, the terminal 2 displays the asking rent and vacancy rate, as well as the trend in the asking rent.

When an operation input to the "Recruitment Information" button 51 is received, the terminal 2 displays the screen shown in FIG. 7. In this case, the terminal 2 displays the recruitment information for the tenant (room floor plan, recruited area, recruited rent, etc.).

Figure 8 is an explanatory diagram showing an example of an owner search screen. Figure 8 shows an example of a search screen centered on the property owner.

The owner search screen includes an owner search field 81. The owner search field 81 is an input field for narrowing down property owners using the first property information or the second property information as search criteria. The terminal 2 accepts input of the name of the property owner to be searched for, the number of properties owned, the average holding period, etc. via the owner search field 81. The server 1 searches the search DB 142 for property owners that meet the specified search criteria.

The server 1 outputs various data related to the searched property owners from the search DB 142. For example, the server 1 calculates and outputs the average property ownership period based on the real estate registration specific information. In addition, the server 1 counts and outputs the number of properties owned by each owner, the number of property sales within a certain period of time, the number of property acquisitions, etc.

The "average holding period" refers to the average period that a right holder (property owner) holds a property. The average holding period is calculated by calculating the holding period of each real estate property from the ownership transfer history (time of acquisition, time of transfer) of one or more real estate properties owned by a right holder, and then calculating the average of those periods.

Terminal 2 displays a list of data related to the searched property owners on an owner search screen. For example, terminal 2 displays the number of owned properties, the number of properties sold, the number of properties acquired, the average holding period, etc., in association with the property owner's name.

Figures 9 and 10 are explanatory diagrams showing an example of an owner details screen. When an operation input to select any property owner is received on the owner search screen, terminal 2 displays the owner details screen shown in Figures 9 and 10.

The owner details screen includes a button 91 for switching the display screen. When an operation input to the "Owned Properties" button 91 is received, the terminal 2 displays the screen shown in FIG. 9. In this case, the terminal 2 displays a list of property information (property name, ownership percentage, year of completion, total floor area, etc.) for each property owned by the owner.

When an operation input to the "Ownership Transfer History List" button 91 is received, the terminal 2 displays the screen shown in FIG. 10. In this case, the terminal 2 displays a list of ownership transfer history information (the date of ownership transfer, the type of ownership, the transfer origin, the transfer destination, the transferred share, etc.).

As described above, the server 1 outputs property information from the search DB 142 in response to a request received from a user and displays it on each search screen.

In addition, when an owner manages a property, there are cases where a nominal limited liability company or special purpose company is established to manage the property, and the nominal owner and the true owner are different. More precisely, the nominal owner is the owner in the name of the registration, but even if the parties involved in the transaction of the real estate property contact the nominal owner when negotiating the sale of the property, the nominal owner does not have the actual decision-making authority for the sale of the property, so they need to contact a person who has the actual decision-making authority for the sale of the property. In preparation for such a case, the server 1 may estimate and output information regarding the contact information for the sale of the property based on the name or address of the property owner indicated in the real estate registration specific information or the resident-related information (the entity of the contact information may be called the true owner). For example, the server 1 may store a list of the names of the true owners in association with the names or addresses of the limited liability companies or special purpose companies. The server 1 refers to the list, estimates the true owner from the name or address of the property owner, and outputs the estimated true owner name. Contact information may include all or part of your name, address, telephone number, email address, etc.

When outputting the search results, the server 1 may also determine whether or not the property is a building for the owner's own use, and output the determination result. For example, the server 1 searches for the location of the property owner (corporation), and if the searched location matches the address of the property, it determines that the building is for the owner's own use. This makes it possible to know whether or not a property searched for as a potential income property is for the owner's own use.

In this embodiment, the server 1 further performs a process of unifying (matching) the names or addresses of each property owner stored in the search DB 142 to the most recent names or addresses.

Specifically, server 1 periodically acquires real estate registration data for each real estate property and extracts first property information from the acquired real estate registration data. Server 1 acquires the latest name change or address change of the property owner from the real estate registration specific information contained in the extracted first property information. Server 1 then refers to the acquired name change or address change and updates the name or address of the property owner stored in search DB 142 to the latest name or address.

However, the above matching process is slow because it is necessary to collect each name or address change for each property every time. Therefore, Server 1 performs the above matching process during specific times when there is little access from users (e.g., at night). In contrast, during times when there is a lot of access from users (e.g., during the day), the matching is performed simply by referencing the update history of the property owner's name or address (owner ID issuance history) as follows:

Specifically, server 1 stores the update history of the property owner's name or address resulting from the above-mentioned name matching process. For example, when server 1 acquires a name change or address change as described above, server 1 stores the new name and address and the old name and address in update history DB 143 in association with the update date (date of registration) of the name or address.

When a request is received from a user, server 1 acquires real estate registration data for the property searched in response to the request, and extracts the first property information. Server 1 refers to the stored update history (update history DB143) of the property owner's name or address, and updates the name or address of the property owner indicated in the real estate registration specific information of the extracted first property information to the latest name or address. Server 1 then outputs the desired data as a search result, based on the real estate registration specific information updated to the latest name or address.

By performing simple name matching as described above, real estate registration data can be provided in real time, since it is only necessary to refer to the file for the target property.

In this embodiment, the server 1 further acquires ownership transfer history information based on the real estate registration receipt book, and performs a process to update the real estate registration specific information stored in the search DB 142. The real estate registration receipt book is a ledger that stores properties for which changes in registration have occurred for each prefecture on a monthly basis. In this real estate registration receipt book, when land and buildings are bought and sold as a set, or when multiple properties are inherited at the same time, only one representative property is updated. Therefore, when the server 1 confirms the transfer of a property in the real estate registration receipt book, it identifies properties that have the same owner as the property in question, and updates the real estate registration specific information in the search DB 142.

Specifically, when server 1 acquires real estate registration receipt book data, it acquires new real estate registration data (register) of the property for which ownership has been transferred based on the real estate registration receipt book data, and extracts the first property information. Server 1 extracts ownership transfer history information of the property from the real estate registration specific information included in the extracted first property information. Then, server 1 updates the real estate registration specific information stored in search DB 142 based on the extracted ownership transfer history information.

This allows real estate registration specific information to be updated based on the real estate registration receipt book.

11 is a flowchart showing the procedure of the process of generating the search DB 142. The process of generating the search DB 142 will be described with reference to FIG.
The control unit 11 of the server 1 reads out the address (second property specific information) of each real estate property from the second property information DB 141 (first database) (step S11). The second property information DB 141 is a database constructed from data other than real estate registration data, and is a database that stores second property information including second property specific information and tenant-related information. The control unit 11 identifies the location of each property on the map using a map search engine based on the read out address, and obtains the land number (first property specific information) of the same location using a land number search service accessible from the information providing site (step S12).

Based on the acquired land number, the control unit 11 acquires real estate registration data (e.g., PDF data of the real estate registry) for each property (step S13). The control unit 11 extracts first property information including first property identification information and real estate registration specific information from the acquired real estate registration data (step S14). The control unit 11 generates a search DB 142 (second database) that stores property information including real estate registration specific information and tenant-related information by associating the extracted first property information with the second property information stored in the second property information DB 141 based on the correspondence between the land number (first property identification information) acquired in step S12 and the address (second property identification information) that was used as the search query when acquiring the land number (step S15). The control unit 11 ends the series of processes.

12 is a flowchart showing the procedure for updating the name or address of the property owner. The process for updating (collating) the name or address of the owner of each real estate property will be described with reference to FIG.
The control unit 11 of the server 1 periodically acquires real estate registration data (step S31). The control unit 11 extracts first property information from the acquired real estate registration data (step S32).

The control unit 11 acquires the latest name or address change of the property owner from the real estate registration specific information included in the extracted first property information (step S33). Based on the acquired name or address change, the control unit 11 updates the name or address of each property owner stored in the search DB 142 to the latest name or address (step S34). The control unit 11 stores the update history of the property owner's name or address (step S35) and ends the series of processes.

13 is a flow chart showing the procedure of the search process, which will be described with reference to FIG.
The control unit 11 of the server 1 receives a request from a user via the terminal 2 (step S51). Specifically, the control unit 11 receives a search query for narrowing down search properties (property name, location area, year of completion, total floor area, etc.) or a search query for narrowing down property owners (owner name, number of properties owned, average holding period, etc.). Based on the received request, the control unit 11 searches the search DB 142 for real estate properties or property owners (step S52).

The control unit 11 acquires real estate registration data for the searched property or for properties owned by the searched owner (step S53). The control unit 11 extracts the first property information from the acquired real estate registration data (step S54).

The control unit 11 refers to the update history of the property owner's name or address stored in step S35, and updates the property owner's name or address indicated in the real estate registration specific information of the acquired first property information to the latest name or address (step S55).

The control unit 11 outputs data based on the real estate registration specific information and tenant-related information for the property searched for in step S52 or for the property owned by the searched owner (step S56). In this case, the control unit 11 outputs the name or address of the property owner indicated in the real estate registration specific information as the latest name or address updated in step S55. The control unit 11 ends the series of processes.

14 is a flow chart showing the procedure of the process of updating ownership transfer history information. The process of updating ownership transfer history information of a property based on the real estate registration receipt book will be described with reference to FIG.
The control unit 11 of the server 1 acquires real estate registration receipt data (step S71). Based on the acquired real estate registration receipt data, the control unit 11 acquires new real estate registration data for real estate properties whose registration information has been changed (step S72).

The control unit 11 extracts the first property information from the acquired real estate registration data (step S73). The control unit 11 extracts the property ownership transfer history information from the real estate registration specific information included in the extracted first property information (step S74).

The control unit 11 updates the real estate registration specific information stored in the search DB 142 based on the extracted ownership transfer history information (step S75). The control unit 11 ends the series of processes.

As described above, this embodiment allows parties involved in real estate property transactions to conveniently collect property information.
