[Outline of taxation information management system S]
FIG. 1 is a diagram showing an overview of the taxation information management system S. As shown in FIG. The taxation information management system S is a system for local governments such as municipalities to manage the tax base amount of property tax, and includes a taxation information management device 1 and one or more information terminals 2 . The taxation information management system S is installed, for example, in government offices and government offices of local governments.

The taxation information management device 1 acquires electronic registration data from a server 3 managed by a legal affairs bureau or the like connected via a network N1, and generates taxation information based on various types of registration information included in the acquired electronic registration data. , is a computer that manages the generated taxation information. The taxation information management device calculates the tax base amount of the property tax based on the generated taxation information.

The taxation information management device 1 stores a taxation information database in which generated taxation information is registered in a storage medium, and responds to requests from one or more information terminals 2 connected via the network N2. 2 to display the taxation information. The information terminal 2 is, for example, a computer used by an employee of a local government. The network N1 is for example the Internet and the network N2 is for example an intranet, but the network N2 may be the Internet.

FIG. 2 is a table showing an example of registration information included in electronic registration data. FIG. 2(a) shows land registration information, and FIG. 2(b) shows house registration information. FIG. 3 is a table showing an example of taxation information on land. FIG. 4 is a table showing an example of taxation information regarding houses. The taxation information shown in FIGS. 3 and 4 is managed in a taxation information database in which the content of each item corresponding to the land or house associated with the same specific information is associated. The specific information is information for specifying land or a house, and includes, for example, a street number indicating the lot number where the land is located, or a house number assigned to the house.

Comparing FIG. 2 with FIGS. 3 and 4, taxation information includes more items than registration information. Some items of the taxation information are the same as the items of the registration information, and the contents of the registration information are directly reflected in the same items as the registration information included in the taxation information. Some other items of taxation information are not included in the registration information, and the contents of these items are generated based on the contents of the registration information or entered by local government officials.

When the taxation information management device 1 acquires new electronic registration data from the server 3, the taxation information management device 1 updates at least the taxation information in the taxation information database with the content indicated by the registration information included in the new electronic registration data. Overwrite the contents of some fields. However, there may be cases where the registration information included in the electronic registration data does not match the current situation. For example, when a house is actually built even though the registered land category included in the registration information of a certain location number is "mountain forest", the taxation information management device 1 registers another address corresponding to the location number. Based on the above information, let the taxable land category included in the land taxation information be “residential land”.

Other information corresponding to the location number is, for example, the house tax information stored in the taxation information management device 1 in association with the house number of the building on the land of the location number, the address number of another adjacent land, etc. or the building tax information corresponding to the house number of the building standing on the adjacent land of another address number, the land of the said address number, or the building standing on the land of the said address number was photographed Photographed image, map image of the location number, field survey results of the land of the location number or the building built on the land of the location number, permission or notification based on the Agricultural Land Law, Fire Service Law, etc., or similar situation classification or drawing It is external information such as evaluation information of places, etc. A map image indicates the position or shape of land or a house, such as a topographic map, a residential map, a lot number map, a public map, a parcel survey map, a floor plan, a building drawing, a floor plan of each floor, a blueprint, or a floor plan. An image of any format.

In this way, when the taxation information management device 1 acquires new electronic registration data, the taxation information corresponding to the specific information such as the location number or the house number is updated based on information different from the registration information corresponding to the specific information. , the taxation information management device 1 can manage appropriate taxation information even when the registration information indicated by the electronic registration data cannot be used as taxation information.

[Configuration of taxation information management device 1]
FIG. 5 is a diagram showing the configuration of the taxation information management device 1. As shown in FIG. The taxation information management device 1 has a communication section 11 , a storage section 12 and a control section 13 . The control unit 13 has an acquisition unit 131 , an information provision unit 132 and an update unit 133 .

The communication unit 11 includes a communication controller for transmitting/receiving data to/from the server 3 via the network N1 and transmitting/receiving data to/from the information terminal 2 via the network N2. The communication unit 11 notifies the control unit 13 of the received data. Also, the communication unit 11 transmits data received from the control unit 13 . The communication unit 11 transmits the display data received from the control unit 13 to the information terminal 2 so that the information terminal 2 displays the display data.

The storage unit 12 includes a storage medium such as a ROM (Read Only Memory), a RAM (Random Access Memory), and a hard disk. The storage unit 12 stores programs executed by the control unit 13 . In addition, the storage unit 12 stores the registration information included in the registration electronic data received by the communication unit 11 from the server 3 and taxation information created based on the registration information or external information in association with a plurality of pieces of specific information. are doing. For example, the storage unit 12 stores land tax information in association with land identification information for identifying land, and stores house tax information in association with house identification information for identifying a house. The land identification information is, for example, information indicating the location number of the land included in the registration electronic data. The house identification information is, for example, information indicating the address number of the land on which the house is built or the house number assigned to the house included in the electronic registration data.

The control unit 13 is, for example, a CPU (Central Processing Unit), and functions as an acquisition unit 131 , an information provision unit 132 and an update unit 133 by executing programs stored in the storage unit 12 . The control unit 13 may further have a calculation unit (not shown) that calculates the standard taxable amount. The calculation unit calculates the standard taxable amount based on the taxation information stored in the storage unit 12 .

The acquisition unit 131 acquires electronic registration data created by the legal affairs bureau via the communication unit 11 . The acquisition unit 131 causes the storage unit 12 to store registration information (for example, land registration information or house registration information) included in the acquired registration electronic data. The acquisition unit 131 causes the storage unit 12 to store the registration information in association with the specific information included in the registration information. The acquisition unit 131 creates taxation information based on the registration information, and causes the storage unit 12 to store the created taxation information. When the registration information and taxation information corresponding to the specific information included in the registration information are already stored in the storage unit 12, the acquisition unit 131 adds the acquired registration information and the created registration information to the stored registration information and taxation information. Override tax information.

The acquisition unit 131 identifies at least one of the items “location”, “lot number”, or “house number” included in the registration information stored in the storage unit 12, and obtains the identified “location”, “ The taxation information stored in the storage unit 12 in association with at least one of "lot number" or "house number" is read. Subsequently, the acquiring unit 131 retrieves the content corresponding to one or more items included in the registration information notified from the communication unit 11 among the plurality of items included in the read taxation information. By matching the contents, the stored tax information is overwritten with the new tax information. When overwriting the stored taxation information with new taxation information, the acquisition unit 131 may cause the storage unit 12 to store the stored taxation information as history information.

The acquisition unit 131 may notify the update unit 133 that the electronic registration data has been received. Further, the acquiring unit 131 may notify the updating unit 133 of the registration information included in the acquired electronic registration data or the created taxation information.

In addition, the acquisition unit 131 may acquire usage status information indicating the usage status of the land or building in association with the specific information. The usage information is, for example, a photographed image of the land of the address number or a building standing on the land of the address number, a map image of the address number, or the land of the address number or the building on the land of the address number This is the survey result. The acquisition unit 131 acquires the usage status information from, for example, the information terminal 2 used by the local investigator or the information terminal 2 of the employee of the government office where the taxation information management device 1 is managed. The acquisition unit 131 causes the storage unit 12 to store the acquired usage information in association with the specific information. The acquisition unit 131 may notify the update unit 133 of the acquired usage information.

The information providing unit 132 causes the information terminal 2 to display a plurality of pieces of taxation information stored in the storage unit 12 . For example, the information providing unit 132 reads from the storage unit 12 the land tax information corresponding to the location number designated from the information terminal 2 or the house tax information corresponding to the house number of the building on the land of the location number. , the read land tax information or house tax information is transmitted to the information terminal 2 via the communication unit 11 . The information providing unit 132 may cause the information terminal 2 to display the standard taxable amount calculated by the calculating unit.

The updating unit 133 changes the taxation information stored in the storage unit 12 in association with the partial specific information, which is at least part of the specific information among the plurality of specific information, to information different from the registration information corresponding to the partial specific information. update based on For example, in response to receiving a notification that the electronic registration data has been acquired from the acquiring unit 131, the updating unit 133 stores the taxation information of the partial specific information corresponding to the registration information included in the acquired electronic registration data. 12 to determine if the tax information is appropriate. The updating unit 133 may determine whether or not the taxation information stored in the storage unit 12 is appropriate in response to receiving an instruction to check the taxation information from the information terminal 2 .

The update unit 133 determines whether the taxation information read from the storage unit 12 is appropriate based on other information different from the taxation information corresponding to the partial specific information associated with the taxation information read from the storage unit 12. You can judge. Other information different from the tax information corresponding to the partial specific information is, for example, tax information associated with the address number of land adjacent to the land of the address number corresponding to the partial specific information. For example, when the partial specific information is a location number, the update unit 133 updates the building tax information corresponding to the house built on the land corresponding to the location number (for example, the land adjacent to the location number). update the land tax information associated with the location number based on When the partial specific information is a house number, the updating unit 133 updates the land tax information of the land corresponding to the land on which the house corresponding to the house number was built (for example, the land adjacent to the land on which the house was built). Based on this, the house tax information associated with the house number may be updated.

For example, when the taxation information read from the storage unit 12 is determined to be inappropriate, the updating unit 133 updates the taxation information based on other information different from the taxation information corresponding to the partial specific information associated with the taxation information determined to be inappropriate. to update tax information. The updating unit 133 corrects the original taxation information based on other information different from the taxation information corresponding to the partial specific information, and stores the corrected taxation information in the storage unit 12, thereby updating the taxation information. do. When the updating unit 133 determines that the taxation information read from the storage unit 12 is appropriate, it does not update the taxation information.

The updating unit 133 may notify the information terminal 2 via the information providing unit 132 of the update before updating the land tax information or the house tax information. For example, before updating the taxation information stored in the storage unit 12, the updating unit 133 causes the information terminal 2 to display a message indicating that the taxation information is to be updated, and instructs the information terminal 2 to update the taxation information. Update tax information after receiving
Processing for updating the taxation information by the updating unit 133 will be described in detail below.

[Processing to update taxation information]
(Updating land tax information based on the condition of houses with the same lot number)
The update unit 133 updates the land tax information stored in the storage unit 12 in association with the location number based on the house tax information stored in the storage unit 12 in association with the house number of the building on the land of the location number. Update. For example, even if the taxable land item of the location number indicated by the land taxation information is other than "residential land", the updating unit 133 may update the information when there is house taxation information of a building on the land of the same location number as the land taxation information. In addition, the taxable land category in the land tax information may be updated to "residential land".

Specifically, even though the taxable land category indicated by the land taxation information stored in the storage unit 12 is “field,” the land indicated by the location number in the land taxation information is such as a residence, a store, a warehouse, or a garage. 2, if there is a building to be taxed, the update unit 133 determines that the taxable land category of "field" is incorrect, and updates the taxable land category of the land tax information to "residential land." By the update unit 133 operating in this way, even though there is a taxable building on the land, when the taxable land category of the land is not “residential land”, the taxable land category of the land tax information is appropriately determined. content can be made.

(Update of house tax information based on the condition of the land on which the house is built)
The update unit 133 updates the house tax information stored in the storage unit 12 in association with the house number based on the land tax information stored in the storage unit 12 in association with the location number of the land on which the building is built. good too. For example, even if the type of building in the house taxation information is "office", the updating unit 133 adds "special residential land" to the land taxation information with the same address number as the address number corresponding to the house taxation information. is applied, the type of building in the building taxation information may be updated to "residence".

(Update based on tax information for other lot numbers)
The updating unit 133 associates the first taxation information stored in the storage unit 12 in association with the first partial identification information with the second partial identification information different from the first partial identification information, and updates the storage unit 12 with the first partial identification information. may be updated based on the second tax information stored in the . The update unit 133 updates, for example, the house taxation as the second taxation information stored in the storage unit 12 in association with the house number of the building on the land of the second location number, which is an example of the second partial identification information. Land tax information as the first tax information is updated based on the information. The relationship between the first location number and the second location number is, for example, the relationship between the location number of adjacent land or the location number of land within a predetermined distance.

For example, the update unit 133 determines that the taxable land category of the land indicated by the first taxation information of the first location number, which is an example of the first partial identification information, is other than "residential land" and is used together with the first location number. If the taxable land category of the land indicated by the second taxation information of the second location number is “residential land”, the taxable land category of the land corresponding to the first taxation information may be updated to “residential land”. Specifically, even if the first location number has a tennis court and the taxable land category of the land in the first taxation information of the first location number is “mixed land”, If there is a building in the second location number that is used together with the first location number, the taxable land category of the land is "residential land", and a tennis court is considered to be attached to the building, The taxable land category of the land in the first taxation information is updated to “residential land”. By the update unit 133 operating in this manner, the taxable parcel category of the land that is used together with other land can be made appropriate.

(Update based on external information)
The update unit 133 may update the taxation information stored in the storage unit 12 in association with the partial specific information based on the usage status information corresponding to the partial specific information acquired by the acquisition unit 131 . For example, when the photographed image or the map image indicates that the land of the location number includes a building, the updating unit 133 updates the taxable land category of the land tax information corresponding to the location number to "residential land." If the updating unit 133 determines whether or not the building included in the land of the location number is a taxable building based on the photographed image or the map image, and determines that the building is a taxable building In addition, the taxable land category of the land tax information corresponding to the location number may be updated to "residential land".

If the photographed image or the map image indicates that a building is included in an area equal to or larger than a predetermined ratio or a predetermined area of the land of the location number, which is an example of the partial identification information, the update unit 133 The taxable land category of the land tax information corresponding to the number may be updated to “residential land”. For example, when the updating unit 133 determines that the area of the object included in the photographed image is not a taxable building (such as a doghouse) but a taxable building (such as a warehouse), the land tax information is subject to taxation. Change the land category to "Residential land".

The updating unit 133 updates the captured image or the map image to indicate that the building is not certified as a building or a building with a predetermined ratio or less even if a building is built on the land of the location number. Alternatively, if the map image includes rice fields or fields, the taxable land category of the land tax information is not updated to "residential land", but the taxable land category of the land tax information is changed to "rice fields" or "fields." By operating the updating unit 133 in this manner, it is possible to prevent the taxable land category of the land tax information from being erroneously updated to "residential land" even though the taxable parcel category should not be "residential land."

If the photographed image or the map image indicates that the photovoltaic power generation facility is installed in an area equal to or greater than a predetermined ratio of the land of the location number, the updating unit 133 updates the land tax information corresponding to the location number. The land category may be referred to as "hybrid land". Due to the updating unit 133 operating in this way, even if a building is included in the photographed image, if most of the land is equipped with photovoltaic power generation equipment, the taxable land category will be incorrectly classified as " It is possible to prevent updating to "residential land".

The update unit 133 updates the land taxation corresponding to the location number when the land area (parcel area) of the location number indicated by the usage status information corresponding to the location number is different from the taxable acreage area indicated by the land taxation information corresponding to the location number. The taxable area of the information may be updated to the area of the land indicated by the usage information corresponding to the location number. By operating the update unit 133 in this way, even if there is an error in the taxable land area of the land tax information due to an error in the land registration information included in the electronic registration data, the photographed image, etc. external information makes it possible to correct errors in taxable acreage.

The acquisition unit 131 further acquires plan information indicating a land or building usage plan based on law, and the update unit 133 updates the taxation information stored in the storage unit 12 in association with the partial specific information based on the plan information. , may be partially updated based on the land or building utilization plan corresponding to the specific information. The law is, for example, the Agricultural Land Law or the Fire Service Law. The plan information is, for example, information indicating legally permitted content or information indicating legally notified content. As an example, the plan information is information indicating that the land will be used as a residential subdivision. The plan information may include evaluation information indicating similar situation divisions, road prices, plots, and the like.

The update unit 133 may use a machine learning model for the above determination. For example, when a captured image of land is input, the updating unit 133 inputs the captured image acquired by the acquiring unit 131 to a machine learning model that outputs the result of determining whether or not the land includes a building. Then, by obtaining the determination result output from the machine learning model, it is determined whether or not the land of the location number includes a building. When a photographed image of land is input, the updating unit 133 updates taxation information using a machine learning model that outputs the type of building included in the photographed image or the ratio of the occupied area of the building to the area of the land. You may update.

FIG. 7 is a diagram showing an example of house tax information stored in the storage unit 12. As shown in FIG. The house tax information shown in FIG. 7 indicates the location number, house number, building type, and building usage status. The usage status of a building is information indicating details of a building specified based on usage status information such as a photographed image, a map image, or a field survey result.

FIG. 8 is a diagram showing land taxation information after updating unit 133 updates the land taxation information shown in FIG. 6 based on the house taxation information shown in FIG. In FIG. 8, the taxable parcel underlined and indicated by a larger character than the other characters is the updated part.

The taxable land category of the land with location number 3 is "residential land" in FIG. Further, the type of building corresponding to location number 3 in the house taxation information shown in FIG. 7 is "residence". However, the usage status corresponding to location number 3 in the house tax information shown in FIG. 7 is "solar panel". The usage status is information determined based on the photographed image obtained by actually photographing the land corresponding to the location number or the result of the field survey, and is considered to be the most reliable.

Therefore, if the building type in the house taxation information does not match the usage status associated with the location number, the updating unit 133 may update the land taxation information based on the usage status regardless of the building type. . Further, if the building type in the house taxation information does not match the usage status associated with the location number, the updating unit 133 may update the building type in the house taxation information based on the usage status.

The taxable land category of the land with location number 4-2 is "field" in FIG. Further, the type of building corresponding to location number 4-2 in the house taxation information shown in FIG. 7 is "garage", and the usage status is "garage". In such a case, the update unit 133 updates the taxable land category of the land tax information to “residential land”.

[Operation Flowchart of Taxation Information Management Device 1]
FIG. 9 is a flowchart of the operation of taxation information management device 1 to update taxation information. FIG. 9 starts from the time when the acquisition unit 131 acquires an instruction to check the taxation information from the information terminal 2 (S1). It is assumed that the instruction acquired by the acquisition unit 131 specifies a plurality of location numbers to be checked.

The update unit 133 first selects one location number from the designated plurality of location numbers (S2). Subsequently, the land tax information and the house tax information corresponding to the selected location number are collated (S3). The details of this processing will be described later.

Subsequently, the updating unit 133 determines whether or not matching of all the location numbers to be checked has been completed. ), and the process returns to S2. When the updating unit 133 determines that matching of all location numbers is completed (YES in S4), the updating unit 133 notifies the information terminal 2 of the matching result via the information providing unit 132 (S5).

FIG. 10 is a flow chart showing an example of the matching process (S3) in FIG.
