It is a figure explaining the polygon information recorded in the polygon information storage unit 7 of the real estate information storage unit 4.

Here, building polygons are stored in each record (building record) held in the database of the building information storage unit 5, and brush polygons are stored in each record (land record) of the land information storage unit 6. ing. These building polygons, brush polygons, and polygons in the polygon information storage unit 7 are defined on a common coordinate axis, and by superimposing them in the information processing system 1, a virtual map is created. It is possible to generate a display and process data.

Further, FIG. 6 is a diagram showing a list of applicants input to the client device 3 in the present embodiment. The applicant list is composed of one or more applicant information (applicant record).

In the following, the information processing system 1 of the present embodiment will be described with reference to FIG. 2 while appropriately explaining FIGS. 3 to 6.

Further, in the first embodiment, the description will be made on the premise that the database of the real estate information storage unit 4 described with reference to FIGS. 3 to 5 is in a nearly complete state in principle. Since each database of the real estate information storage unit 4 requires a great deal of labor to construct and maintain, it is assumed that records and fields are partially missing. The second embodiment and the third embodiment are configured in consideration of the fact that the real estate information storage unit 4 is in a transitional state, and the details thereof will be described later.

The server device 2 and the client device 3 of the present embodiment include storage elements such as RAM (Random Access Memory) and ROM (Read Only Memory), a storage area composed of a hard disk and the like, and a CPU (Central Processing Unit) and the like. It is realized by including a program control device. In the server device 2 and the client device 3, each function is realized by the CPU executing a program stored in a storage area such as a hard disk.

The server device 2 includes a real estate information storage unit 4 and a registration information acquisition unit RG, and the client device 3 includes an applicant information acquisition unit OG, a building information inquiry unit AQ, and an ownership status determination unit PJ. Consists of including.

In the information processing system 1 of the present embodiment, the address information of the applicant input to the server device via the client device 3 is inquired by the real estate information storage unit 4 of the server device 2, thereby making a credit card contract. It is possible to make a judgment regarding the real estate owned by the applicant.

First, the server device 2 of the present embodiment is configured to include an immovable information storage unit 4 that stores attribute information of real estate in a predetermined area, and the real estate information storage unit 4 further includes a building information storage unit 5 and a land. The information storage unit 6 and the polygon information storage unit 7 are included. The building information storage unit 5 is a database that holds information such as the position of the building on the register (information in the fields of No. 1 to NO. 4), its address, and information on ownership, and is a land information storage unit. Reference numeral 6 is a database that holds information on the position of the land on the register (information on the fields of No. 1 to No. 4) and information on the ownership. Further, the building information storage unit 5 and the land information storage unit 6 also hold building coordinate information (for example, building polygon) and land coordinate information (for example, brush polygon) corresponding to public coordinate values for the building and land, respectively. is doing.

Here, the building information storage unit 5 of the present embodiment holds a database for recording a plurality of records (building records) corresponding to a single building as a unit of registration, and FIG. 3 shows the field names thereof. It is a diagram for explaining. The information of "prefecture", "city", "character / town" is information indicating the location of the building, and by combining these with the information of "house number", the building can be uniquely identified. Will be done.

In addition, the "address" is used as information for identifying the building on a daily basis, but in the municipality where the address is displayed, it is the address by the "address", and in the municipality where the address is not implemented, the "lot number". It will be the address according to the notation. Addresses based on "house number" are basically composed of prefectures- (county) -municipalities / special wards-towns / characters-towns-house numbers, and addresses based on "lot number notation" are prefectures- (county)-. It is composed in principle by municipalities / special wards-towns / characters-lot numbers. For this reason, in the address by "house number display", the information of that part is stored in the fields (NO.6 to 7) of "block" and "house number" which are subordinate to the field of "address", and it is based on "lot number notation". In the address, the information of the part is stored in the subfield (NO.8) of the "lot number" (sometimes referred to as "address").

In addition, "type (use)", "structure", "floor area", "building time", "owner", "information on ownership", and "information on rights other than ownership" are NO. 1-NO. Similar to field 4, the information is based on the real estate registry of the building (Note that the information other than "information on ownership" and "information on rights other than ownership" is provided by the real estate registry. For buildings that do not exist, other official documents such as a building plan summary may be used as the source.) "Information on ownership" is information corresponding to the "Rights Department (Kou-ku)" in the register, "Purpose of registration" such as transfer of ownership, and "Reception date" when the registration was accepted. , "Reception number", and "owner" after the transfer of ownership. In addition, "information on rights other than ownership" is information corresponding to "Rights Department (Otsu Ward)" in the register, "Purpose of registration" such as setting of mortgage, and "Registration" was accepted. It includes the "reception date", "reception number", "credit amount", "debtor", and "mortgagee" of the mortgage.

The "building coordinate information (building polygon)" indicates (or includes) a plurality of bending point coordinate values for forming a building polygon indicating the position of the building on the map, and is a national land base map or a national land base map. , Obtained from aerial photographs and other official documents. In this embodiment, building polygons are periodically acquired by these. (Note that the building coordinate information may be not a building polygon but one coordinate / representative point indicating a specific position on the map.)

The building record in the present embodiment is generated by comprehensively acquiring registration information, official drawings, and building drawings of buildings in a predetermined area, for example. Further, in the case of generating a building record from a building polygon acquired from an aerial photograph or the like, for example, it is determined that the building record overlaps with the brush polygon on the map, and the lot number of the land record having the overlapping brush polygon is used on the land. It is also generated by deriving the house number of the building (that is, the building related to the building polygon), acquiring the real estate registry based on this house number, and converting it into data. If there are multiple buildings in one stroke of land, the house numbers will be assigned regularly (if there are multiple buildings in one stroke of land, the numbers will be assigned in ascending order to avoid duplication. The house number of each building polygon is derived based on a plurality of aerial photographs acquired at predetermined intervals. In addition, the address related to each building polygon (furthermore, the house number, etc.) can be derived by referring to, for example, the house display ledger managed by the local government, whereby the location of the building, the house number, the building polygon, the address, etc. can be derived. It is possible to generate a building record with the information of. However, this is an example of a building record generation method, and there may be a generation method using administrative documents other than the above, and in addition to the above method, comprehensiveness, accuracy, and freshness can be improved by using administrative documents other than the above. It is possible to improve. For example, in the case of a local government where the comparison table between the lot number and the addressing system is open to the public, it is possible to improve the comprehensiveness and accuracy by collating this with the above-mentioned generated data and investigating inconsistent points. can.

In addition, "presence or absence of building plan summary" is entered as "yes" when the building plan summary information has been acquired, and "no" when the information has not been obtained. Is entered. If "Yes" is entered, the information described in the building plan summary is entered in some fields such as "Owner" and other fields not shown. In addition, the "lost / closed flag" is a field in which information to that effect is input when "lost" or "closed" is registered, and "lost" or the like is registered. In some cases, the registration of the building is treated as no longer exists. In addition, the "lost / closed flag" is acquired by the registration application information, and by providing this field, it is possible to reflect the disappearance of the building etc. in the building database earlier than the aerial photograph etc. become.

Next, the land information storage unit 6 of the present embodiment holds a database that records a plurality of records (land records) corresponding to one stroke of land, which is one unit of registration, and FIG. 4 shows the field names. It is a diagram for explaining. As shown in the figure, the land records in the database stored in the land information storage unit 6 include information on "prefectures", "municipalities", and "characters / towns", and these are It is information indicating the location of the land, and by combining these with the information of the "lot number", the land can be uniquely identified. This "prefecture", "city", "character / town", and "lot number" information is based on the real estate registry of the land.

Further, the "block" is a field for storing information on the block to which the one-stroke land corresponding to the land record belongs when the area where the residential address is displayed is implemented. The information stored in such a "block" field is acquired, for example, by deriving a block polygon that overlaps with the brush polygon on the map.

In addition, "land", "area", "owner", "information on ownership", and "information on rights other than ownership" are also information acquired based on the real estate registry of the land. As in the case of buildings, "information on ownership" includes information such as "purpose of registration" such as transfer of ownership, and "information on rights other than ownership" is also mortgaged. Information such as "purpose of registration" such as setting of rights is included.

In addition, "land coordinate information (brush polygon)" is information indicating a plurality of bending point coordinate values for forming a brush polygon indicating the boundary of one stroke of land on a map, for example, a public map or a public map. It can be obtained by digitizing the coordinate values shown on the geological survey map. In addition, in the field of "location information (latent address)", in the case of a residential address, the house number of a building that may be built on the brush polygon based on the positional relationship between the block polygon and the brush polygon. Candidates are requested and stored in advance, and in the case of a lot number display area, the lot number that can be a part of the address of the building to be built on the land is stored. Further details of this "location information" will be described in the second embodiment.

In addition, in the fields of "school district information", "hazard map information", "road price", "public land price", and "contour line (elevation value)", information on the school district to which the land belongs, information on the hazard map, and information on the hazard map are added. The land price, official land price, and elevation value are stored respectively. In addition, in the field of "vacant lot flag", when a building is not built on the land, information indicating that it is a vacant lot is recorded, for example, a brush polygon. Whether or not it is a vacant lot is determined based on collation with building polygons and visual inspection of aerial photographs.

The land record in the present embodiment is generated by comprehensively acquiring registration information and official maps of land in a predetermined area, for example.

The polygon information storage unit 7 of the present embodiment records the coordinates of bending points such as "prefecture polygons". These polygons are superimposed on the building polygon of the building information storage unit 5 and the brush polygon of the land information storage unit 6, and a process of generating the building position information described later is performed. In the field such as "school district information" in the brush polygon, the ID information of the school district polygon is stored, and the information about the bending point coordinate value on the map coordinate axis for defining the polygon is stored in the polygon information storage unit 7. You may. Similarly, the identification information of the building polygon is recorded in the field of "building coordinate information" in the building table, and is associated with the identification information of the building polygon in the polygon information storage unit 7, and a plurality of bending points constituting the building polygon. Coordinate values may be recorded.

The server device 2 has the real estate information storage unit 4 as described above, and further has a registration information acquisition unit RG. The registration information acquisition unit RG uses, for example, an internet line, and the Foundation Law People's Affairs Access the registration information service provided by the Legal Association to obtain registration information. The registration information acquisition unit RG may periodically acquire registration application information from the outside to acquire registration information about the real estate in which the registration has changed, or may obtain the registration information of the building information from the client device 3 described later. In response to the inquiry, the registration information of the building record to be inquired may be acquired (updated). The registration information acquisition unit RG reflects the content of the acquired registration information in the real estate record recorded in the real estate information storage unit 4 (generates a new building record, etc., or is recorded in an existing building record, etc.). Update information).

The registration application information includes the date of reception when the registration application was made, the reception number that identifies the application, the name of the prefecture, the name of the city, ward, town, and village as information that identifies the target property for which the registration application was made, and large letters.・ Information that includes data such as town name, lot number and house number, purpose of registration, and usage. Registration application information can be obtained, for example, from the real estate registration reception book written on a paper basis from the Legal Affairs Bureau, thereby monitoring changes in the register (registration changes) that occur in real estate within a given area. be able to. Further, the registration application information in this embodiment is converted into data in a table format in which "lot number and house number" are used as fields and is accepted by the server device 2, and one record of the registration application information is in principle. In addition, it corresponds to a part of the contents of one registration application for one real estate.

Next, the configuration of the client device 3 will be specifically described.

The applicant information acquisition department OG acquires information about the applicant such as a credit card contract. The information about the applicant includes information indicating the name of the applicant (name information) and information indicating the address of the applicant (address information), and the applicant information acquisition unit OG includes other servers. The information about the applicant may be acquired via the network or the network, or the information may be acquired by the input of the user of the client device 3, and the applicant information list including the information about a plurality of applicants may be acquired. It may be (see FIG. 6 (a)).

Further, the applicant information may include name information and other information of address information (for example, spouse's name information, whether the building to be the address is a rented house or a owned house, etc.). By including such other information, the accuracy of the judgment in the following ownership status judgment unit PJ can be improved, but if the applicant is requested to input other information, the burden increases and the speed is increased. It will diminish the effect of credit business processing that requires sex.

The building information inquiry unit AQ transmits the address information of the applicant to the server device 2 and inquires about the building record corresponding to the address information. The server device 2 receives the address information together with the inquiry from the client device 3, searches the field field of "address" in the building table, and identifies the building record in which the data having the same content as the received address information is recorded. do. The building information inquiry unit AQ receives at least a part (preferably all) of the contents of the building record specified by the server device 2 from the server device 2.

The ownership status determination unit PJ is a building (including a sectioned building) that is the address where the applicant resides based on the contents of the building record received from the server device 2 by the building information inquiry unit AQ and the name information of the applicant. Make a judgment as to how you own the.

More specifically, the ownership status determination unit PJ includes an address existence determination unit P1, an ownership determination unit P2, and a serviceability determination unit P3. In principle, the address existence determination unit P1 in the present embodiment actually does not record in the building information storage unit 5 the record of the building corresponding to the address that the applicant should have described at the time of contract. It is determined that the applicant has entered a fictitious address that does not exist as address information. A non-residential facility in the "type" field of the building record, even if the building record corresponding to the address that the applicant should have entered at the time of the contract is recorded in the building information storage unit 5. When the content to the effect is stored, it may be determined that the applicant has entered a fictitious address that does not actually exist as the address information, as described above.

Next, in the ownership determination unit P2, when the record of the building corresponding to the address described by the applicant is recorded in the building information storage unit 5 (in the address existence determination unit P1, the applicant is not fictitious). If it is determined that the application was made at the address to be used), the address entered by the applicant will be based on the information about the owner of the building recorded in the record of the building and the name information of the applicant. Determine if you own the corresponding building. Specifically, when the "last name / first name" of the applicant and the "last name / first name" of the owner of the building match, the ownership determination unit P2 indicates that the applicant owns the building. Judgment is made as. In addition, if the spouse's "last name / first name" is entered and the spouse's "last name / first name" and the building owner's "last name / first name" match, , The ownership determination unit P2 determines that the applicant owns the building. If only the "last name" of the applicant and the "last name" of the owner of the building match, it is determined that the relatives or relatives of the applicant own the building, and the "last name / first name" is determined. "Is treated as if they match (that is, they are treated in the same way as if the" first and last name "matches). On the other hand, if the "last name" of the applicant does not match the "last name" of one or more owners of the building, the building corresponding to the address stated by the applicant is the applicant or Judge that it is unlikely that it is owned by the relative. (Note that the ownership determination unit P2 applies by determining whether the building corresponding to the address stated by the applicant is a rental residential facility, etc., based on the "type (use)" in the building record. It may be possible to increase the precision of the determination as to whether or not the person owns the building corresponding to the address stated by the person.)

Then, when the ownership determination unit P3 determines that the applicant, his / her spouse, or his / her relatives own the building, the mortgage determination unit P3 provides information on the mortgage set for the building. Based on the above, it is determined whether or not the building is provided to others as collateral.

Specifically, the responsibilities determination unit P3 of the present embodiment is a functional block that determines whether or not the applicant has a mortgage, and in the record of the building information storage unit 5. Based on information other than the retained ownership, it is determined whether or not the building corresponding to the address stated by the applicant was acquired by setting a mortgage. For example, (1) whether or not the building is a non-rental residential facility (residential or compartmentalized ownership building), and (2) the first mortgage, which is not a root mortgage, is set for the building. Whether or not the mortgage is granted (3) The first mortgage is within the specified period based on the date of registration at the time of new construction of the building or the date of registration of transfer of ownership due to transferability (for example, from these registrations). Whether or not it is set within 2 months), (4) Whether or not the mortgagee of the first mortgage is a specific organization (bank / financial institution that develops mortgage services), ( 5) Judging the conditions such as whether the debtor of the mortgage is the owner of the building, and if all the conditions are met, it is judged that the mortgage was acquired by setting the mortgage. May be good.

In addition to the above (1) to (5), the above-mentioned responsibilities determination unit P3 further provides information on the asset value of the building corresponding to the applicant's address, for example, by the applicant information acquisition unit OG. Is acquired, and it is determined whether or not the loan is a mortgage based on the information on the asset value and the information on the amount of the claim contained in the information on the non-ownership held in the record of the building information storage unit 5. ((6) That is, whether or not the asset value of the building declared by the applicant is less than or equal to the amount of the claim stated in the information regarding non-ownership). Furthermore, (7) whether the building owner resides in the building that was the object of the mortgage, (8) whether a joint mortgage is attached to the mortgage setting, (9). It may be determined whether or not the mortgage is a mortgage based on conditions such as whether or not the mortgage has been extinguished. The servability determination unit P3 may determine whether or not the loan is a mortgage based on all of the conditions (1) to (9), for example, (1) to (5). And (9) may be used to simply determine whether or not the loan is a mortgage, or the determination may be made based on any one of (1) to (9). ..

As a credit card company, if it is determined by the address existence determination unit P1 that there is no building corresponding to the address stated by the applicant, either do not conclude a credit card contract or lower the credit assessment. Set. In addition, when it is determined by the ownership determination unit P2 that the owner of the building corresponding to the address stated by the applicant is not the applicant, spouse, or relative, the credit card loan facility is high. Try to lower your assessment. Alternatively, if it is determined by the responsibility determination unit P3 that a mortgage is set for the building corresponding to the address stated by the applicant, the appraisal of the loan facility by the applicant's credit card is evaluated low. (See FIG. 6 (b)). As described above, the information processing system 1 of the present embodiment can contribute to the determination of the credibility and economic power of the applicant based on the applicant information including the name and address of the applicant.

Next, the flow of processing executed by the information processing system 1 of the present embodiment will be described with reference to FIG. 7. FIG. 7 (a) is a diagram showing the flow of the possession status determination process, and FIG. 7 (b) is a diagram showing the flow of the serviceability determination process in S605.

First, in the information processing system 1 of the present embodiment, after acquiring the applicant information, by inquiring to the building information storage unit 5, it is determined whether or not there is a building record using the address information input by the applicant as a key. (S601). In S602, the address is fictitious when there is a record (hereinafter, also referred to as an address correspondence record) that holds the content corresponding to the address information entered by the applicant in the "address" field. It is determined that it does not exist, and the process proceeds to S603.

Next, in S603, the ownership status determination unit PJ compares the content of the "owner" field in the address correspondence record with the name information input by the applicant. In S604, if the surname / first name of the applicant and spouse and the surname / first name of the owner of the building match, or only the surname matches, the applicant, spouse, or their relatives have an address correspondence record. It is determined that the building corresponding to the above is owned, and the process proceeds to S605.

In S605, as shown in FIG. 7B, the process of determining the responsibilities is executed.

As shown in FIG. 7B, in S605a of the serviceability determination process, it is determined whether or not all the registered items of the address correspondence record are recorded in the building information storage unit 5, and when this is denied. , Judge whether or not the building plan summary information exists. In principle, S605a and S605f are processes that can be omitted when the building information storage unit 5 is complete (the registration information in the building records of all existing buildings is complete). The details of the building plan summary document information will be described later in the third embodiment, but the S605a and S605f are useful processes in the third embodiment in which the building information storage unit 5 is in a transient state. It becomes. In S605a, specifically, in the case of a building record in which all the registered items are not recorded (no registration information) and the building plan summary information exists (YES), the transfer is made at present. Since it is interpreted as an unregistered building that has no plans to do so, proceed to S605f and determine that there is no mortgage.

Next, if the result is NO in S605a (when the registration information is recorded in the address correspondence record), proceed to S605b and mortgage in the "information on rights other than ownership" field of the address correspondence record. Determine if the right has been set. In S605b, when it is determined that the mortgage is not set, the process proceeds to S605f, and when it is determined that the mortgage is set, the process proceeds to S605c to determine whether or not the mortgage is a mortgage. judge.

Then, in S605c, the burden determination unit P3 determines whether or not the mortgage is set by the mortgage depending on whether or not all of the above-mentioned conditions (1) to (5) are satisfied. do. If all of the conditions are satisfied, proceed to S605d and determine that "the applicant or spouse (or their relatives) has a mortgage", and if any of the conditions is not satisfied. Goes to S605e and determines that it is not a mortgage (that is, it is a mortgage setting by a business loan).

In the information processing system 1 of the present embodiment, the process of determining the ownership status of the building corresponding to the address of the applicant is executed as described above. As a user of the client device 3, if it is determined in S602 that the address does not exist (or a non-residential facility), the applicant maliciously inputs an address that does not exist (or a place that does not exist as an address). Since it is highly probable that the contract itself has been canceled, the contract itself such as a credit card may be cancelled. Further, in S604, if it is determined that the applicant himself or his relatives do not own the building corresponding to the address, the credit evaluation of the applicant is lowered (or the evaluation is to put it on hold temporarily). ) May be possible, and if it is determined in S605 that there is a mortgage, the credit evaluation of the applicant may be lowered (or the evaluation shall be temporary suspension). good.

[Second Embodiment]
Next, the information processing system 1 of the second embodiment of the present invention will be described.

Conventionally, when the Legal Affairs Bureau looks up a lot number, a house number, etc., it is simply a superposition of the image data of a public map on the image data of a house map. The lot number or house number recorded in the register is not recorded in association with the building coordinate information indicating the coordinates on the map, such as a building polygon.

Here, as the information processing system 1, it is desirable that each database of the real estate information storage unit 4 is complete and maintained in the latest state, but the database of the real estate information storage unit 4 requires a great deal of labor to construct. As the area covered becomes wider, the amount of information becomes enormous. Further, even if the real estate information storage unit 4 is updated or maintained by the registration application information described in the first embodiment, the load of the update process is large because the amount of information is large.

Therefore, in the information processing system 1, each database of the real estate information storage unit 4 is up-to-date in a state where records are only partially accumulated or not updated (that is, wholly or partially). It is also assumed that it will be operated on the assumption that it is not maintained in a state).

In the following, the construction and maintenance of each database in the real estate information storage unit 4 will be described.

The contents of the land database in the land information storage unit 6 are good because the change of the brush polygon itself is triggered by the division or the combined writing. In addition, it is possible to construct and manage it by updating it with the acquisition of registration application information (registration transfer information) regarding separate writing and combined writing.

Further, as shown in FIG. 5, the polygon information in the polygon information storage unit 7 is information with little fluctuation and is also information actively published by local governments and the like, so that various types of information are provided in a predetermined area. It is considered relatively easy to keep the polygon information up to date.

Regarding the building database in the building information storage unit 5, new construction (title registration) and demolition (loss registration) of the building occur more frequently than the division of land. For this reason, even if the registration information of buildings in the area is comprehensively acquired and grasped from the Legal Affairs Bureau at a predetermined timing, the disappearance / generation cycle of each record itself in the building database is short, and the building polygons fluctuate frequently. , It becomes obsolete sooner.

Further, even if the above-mentioned registration application information is acquired and the contents of the building information storage unit 5 are updated, the number of registration application information required for the update tends to increase. Therefore, the building database of the building information storage unit 5 is used. The cost of maintaining it will be high. Also, considering that the existence of each record in the building database fluctuates more frequently than that of land, it is assumed that the updated record will disappear without being referenced / queried, and there is room for reduction of acquisition / update costs. It is thought that there is.

As described in the first embodiment, the building information storage unit 5 associates the house number with the building polygon based on the aerial photograph acquired periodically and the list of house numbers. , It is also conceivable to generate a building record by associating a building polygon with an address display by referring to the addressing system. However, there are many exceptional cases, and it is not always possible to reliably generate building records by such processing. Therefore, it is assumed that one of the building polygon, the address, and the house number is missing in the building record.

From the above, in the information processing system 1 of the second embodiment, it is not always premised that the registration information of the building is comprehensively acquired or updated by the registration application information, and the registration information of the already collected building is retained. , Registration information is acquired in response to a request or inquiry from the client device 3.

Further, in the second embodiment, for example, the address information from the client device 3 is used as a key because there is a building record lacking the information in the "address" field (or the building record itself does not exist). In the search, it is assumed that the building corresponding to the address information cannot always be specified, and the land corresponding to the address information is first specified, and then the registration information of the building built on the land is acquired. (Note that there are four valuations for building records that lack information in the "address" field, depending on the presence or absence of "fields corresponding to registration information (house number, etc.)" and "building polygons". If any of these information is missing, the building record itself does not exist).

FIG. 8 is a diagram showing a functional configuration of the information processing system 1 of the second embodiment. As shown in the figure, the server device 2 of the second embodiment is further configured to include a location information generation unit PA and a land identification unit LI.

The location information generation unit PA generates information stored in the location information (latent address) field for the land record recorded in the land information storage unit 6. Here, the location information is information that directly or indirectly corresponds to the address given by the building when the building is built on the land of one stroke. In this embodiment, the address information is used. It corresponds to the house number or lot number used for the address. When the land specified by the predetermined record belongs to the residential addressing system, the location information generation unit PA generates location information based on the positional relationship between the brush polygon of the land and the block polygon to which the land belongs. Further, in the case of a lot number display area, the location information generation unit PA generates location information based on the information stored in the lot number field in the same record.

In the following, the process of generating the location information of the land record belonging to the residential addressing system will be described with reference to FIG.

FIG. 9 is a diagram for explaining a method of determining a house number assigned when a building is built on the land when the land belongs to the residential addressing system. In the figure, there are 6 lands (brush polygons 1 to 6) in one block (block polygon), and one or two buildings exist in each land.

For example, the basic number is set in order for each area (frontage) divided clockwise at predetermined intervals (10 m, 15 m, etc.) along the outer circumference from the apex of the block near the center of the municipality. To. In the case of the example of FIG. 9, starting from the upper left apex in the figure of the block polygon, the basic numbers are sequentially assigned at the frontage every 10 m in the clockwise direction. That is, in the building built on the brush polygon 1, any of the basic numbers 2 to 6 may be assigned as a house number depending on the position of the entrance.

In the server device 2, information on whether it is a residential addressing area or a lot number display area is recorded for each local government, and in the case of a residential addressing area, the above-mentioned basic number setting rule is also used. It is recorded (the rules for setting basic numbers are slightly different for each municipality). The location information generation unit PA generates location information in the location information field of the record recorded in the land information storage unit 6 based on the brush polygon and the block polygon while referring to these information. (Note that the land information storage unit 6 and the building information storage unit 5 adopt a table configuration different from the table configuration of the present embodiment, and the location information field exists in the building information storage unit 5 instead of the land information storage unit 6. In this case, for example, when the location information generation unit PA generates temporary or potential location information, a record having the contents is newly installed in the building information storage unit 5. May be done.)

The location information in this embodiment is configured to include information other than the house number (information on cities, wards, towns and villages, towns and characters), but these information are in the land table (see FIG. 4). NO. 1-3 and NO. It is also the information stored in the field of 5, and is appropriately omitted in the description described later.

Further, the land specifying unit LI searches for the location information of the building generated by the location information generation unit PA using the address information input from the client device 3 as a key, and identifies the land corresponding to the address information. Explaining with reference to FIG. 9, when the address information is the address display district, the land corresponding to the basic number is specified. Specifically, when the house number (basic number) included in the address information is 7, the land of the lot number 2 (brush polygon 2) is specified, and when the basic number is 6, the lot number 1 or The land of lot number 2 (brush polygon 1 or 2) will be specified.

Then, the registration information acquisition unit RG acquires the registration information of the building built on the land based on the location / lot number of the land specified by the land identification unit LI. Then, when the record corresponding to the registration information of the building acquired by the registration information acquisition unit RG does not exist in the building database in the building information storage unit 5, the server device 2 newly establishes a new record and acquires the registration. Record the content of the information in a new record. If the server device 2 determines that a record corresponding to the building registration information acquired by the registration information acquisition unit RG exists, the contents of the record are updated based on the acquired registration information.

Further, it is assumed that the building information storage unit 5 may generate a building record in which only the building polygons are known, based on an aerial photograph or the like. When one building polygon has a one-to-one correspondence in the one-stroke land specified by the land identification unit LI (specifically, when a land such as lot number 1 in FIG. 8 is specified), the relevant case is concerned. The registration information of the building acquired by the registration information acquisition unit RG is associated and recorded in one building polygon.

Further, as in the case where the land of lot number 2 in FIG. 9 is specified, it is assumed that a plurality of building records are generated based on two building polygons on one stroke of land. In such cases, first identify the order in which the two buildings were built based on multiple aerial photography information (preferably taken regularly at predetermined times), and then the Legal Affairs Bureau. Obtain a list of house numbers or registration application information obtained from, and determine the house numbers of the two buildings based on this. In the list of house numbers in the Legal Affairs Bureau, in principle, the buildings are listed in ascending order with the youngest number. (In addition, after specifying multiple house numbers assumed from the lot number of the one-stroke land from the list of house numbers obtained from the Legal Affairs Bureau, the building drawing (building position) from the Legal Affairs Bureau based on the multiple house numbers. The arrangement relationship is recorded.) By acquiring the contents and checking the contents, the connection between each building polygon and the house number can be maintained.)

As described above, in the case of FIG. 9, for example, when the basic number of the address information input from the client device 3 is "6", the land of the lot number 1 or 2 is determined by the land identification unit LI. Will be identified. Then, the registration information of all the buildings in the lot number 1 and the lot number 2 is acquired, and the acquired registration information is reflected in the building information storage unit 5 according to the state of the building record.

In the information processing system 1 of the second embodiment, the applicant information input by the client device 3 is inquired by the real estate information storage unit 4 of the server device 2, as in the case of the first embodiment. .. At this time, if the address information included in the applicant information is not recorded in the building table of the building information storage unit 5, the location information generation unit PA generates the location information of the building and becomes the address of the applicant. The land on which the building is presumed to be built is identified. The server device 2 acquires the registration information of the building built on the estimated land based on the location and lot number of the estimated land, and generates a building record from the acquired registration information (or already exists). It is reflected in the building record to be used).

Then, the client device 3 confirms the content recorded in the "owner" field of one or more newly generated building records (building records reflecting the registration information) and the name information of the applicant, and the first As in the case of the first embodiment, the ownership determination and the like are executed and the credit evaluation is performed.

In the following, the flow of the address existence determination process in the information processing system 1 of the second embodiment will be described with reference to FIG.

As shown in FIG. 10, in the address existence determination process of the second embodiment, first, is the building record specified in the database (building information storage unit 5) using the address information described by the applicant as a key? Whether or not it is judged. When a building is searched in this S901, the process is terminated as it is in principle (registration information is acquired and the building record is updated as necessary). If the building is not specified in S901, the process proceeds to S902, and it is determined whether the building belongs to the municipality of the residential addressing area or the lot number display area. If it belongs to the residential addressing system (S903), the location information generation unit PA generates a house number that may be attached to each brush in the same block as the address information of the applicant, and each land record. Store in the location information field of. If it belongs to the lot number display area (S904), the location information generation unit PA generates the location information of the building in the land record having the same town / character and lot number as the address information of the applicant (that is,). In the case of S904, a potential house number that is location information is generated based on the lot number of the land, and the land corresponding to the address information is specified as it is. Therefore, the address information, the lot number, and the lot number are used. The house number will indicate the same content).

From the location information generated by the steps of S903 and S904, the address of the building to be built in the future (or the address of the building to be built) is required for each brush, and the land identification department LI is described by the applicant. Identify the land where the building corresponding to the address can exist (S905).

Regarding S903 and S905, the case of specifying the land where the building having the address corresponding to the house number "6" in the example of FIG. 9 is located will be described. First, in S903, each land in the block polygon (brush). Generate the location information of polygons 1 to 6). In this case, the location information of the brush polygon 1 on the land is "2", "3", "4", "5", and "6", and the location information of the brush polygon 2 on the land is "6", "7", and "8". .. Then, in S905, the land identification unit LI identifies the land including the location information corresponding to the house number "6", and the land corresponding to the brush polygons 1 and 2 is specified.

Then, in S906, the registration information acquisition unit RG acquires the registration information of the building built on the land specified in S905, and the acquired registration information is reflected in the building information storage unit 5.

In the second embodiment, the input of the applicant information from the client device 3 is accepted, and when the building record corresponding to the address does not exist, the location information is generated and the registration information is acquired. ing. However, as a modification of the second embodiment, the location information may be derived and held in advance in the record corresponding to each brush of the land information storage unit 6 regardless of the input from the client device 3, or the client. Every time the applicant information is input from the device 3, the location information may be derived and the registration information may be acquired.

The information processing apparatus 1 of the second embodiment is the same as the information processing apparatus 1 of the first embodiment except for the above-mentioned points, and the description of the same points will be omitted as appropriate. ..

[Third Embodiment]
Next, a third embodiment of the present invention will be described. In each of the above embodiments, it is premised that a registration exists for an existing building. However, in the case of a building that is not planned to be transferred in the future, the owner does not necessarily register it.

If there is no registration by the owner, the existence of the building will be confirmed, for example, in the aerial photograph, even though the registration information itself cannot be obtained from the Legal Affairs Bureau. Therefore, there may be a building record generated only by the building coordinate information (for example, a building polygon) indicating the coordinates on the map of the building, and the information about the address, the house number, etc. is not prepared in the building record. It is assumed that it has become.

Therefore, in the information processing device 1 of the third embodiment, the server device 2 of the second embodiment further has a building plan summary document information acquisition unit, and the building plan summary document information acquisition section is a local government through an internet line. To get the building plan summary information. The building plan summary information acquisition unit in the present embodiment attempts to acquire the building plan summary information, for example, when the registration information acquisition unit RG cannot acquire the building registration information in S906. .. In addition, the building plan summary information includes the target building coordinate information (building polygons indicating the spatial coordinates and shape of the building, information indicating the spatial representative point coordinates of the building, etc.) and the target building. It is acquired based on the information about the built land (specifically, the information indicating the location and lot number of the land). Specifically, the building plan summary information acquisition unit is based on the information contained in the land record in which the building polygon recorded in the real estate information storage unit and the brush polygon corresponding to (overlapping) the building polygon are associated with each other. , Acquire building plan summary information.

This building plan summary is a document that can be viewed in the municipality where the building manager is located, and the building plan summary information is an electronic version of the information described in the document, even if the building is not registered. Even if there is, it is a document and information that always exists if it is a constructed building. Specifically, the building plan summary document information includes not only the attribute information such as the outline and inspection of the building, but also the owner of the building and the location / lot number of the land on which the building is built. It may also include address information that will be attached to the building in the future. By using such building plan summary information, even if the building registration does not exist, it is possible to confirm whether or not the building exists and the attribute information such as the building owner (that is, the owner of the building). can do.

FIG. 11 is a diagram showing a flow of address existence determination processing in the third embodiment. As shown in the figure, the flow of the address existence determination process in the third embodiment is the same as that in the second embodiment in the steps S901 to S905, and is different in the steps after S905.

In S905, after the land where the building corresponding to the address described by the applicant exists is specified, in S910, it is determined whether or not the registration information of the building constructed in the specified land has been acquired. Then, in S911, the registration information of the building acquired in S910 is reflected in the building record recorded in the building information storage unit 5.

On the other hand, in S910, if the registration information of the building constructed on the land specified in S905 is not acquired, the local government that manages the specified land is accessed through the Internet line, and the building plan summary information is obtained. Acquire (S912). When the building plan summary document information is acquired, proceed to S913, and while reflecting it in the building record of the building information storage unit 5 based on the acquired information, "presence or absence of the building plan summary document" in the building record. Write "Yes" in the "Yes" field. In addition, if the building plan summary information is not acquired, proceed to S914, determine that the building plan summary information corresponding to the address stated by the applicant does not exist, and in the building record. Write "None" in the "Building Plan Summary" field. In addition, based on the determination that the building plan summary information does not exist in S914, it may be determined that the building itself at the address described by the applicant does not exist, and the credit assessment may be lowered.

In S905, one or more lands may be specified, and in S910, if the registration information of the building in any of these lands is not acquired, the process proceeds to S912 or the like to register the building. The building plan summary document information of the building built on the land where the information was not acquired may be acquired and reflected in the building information storage unit 5.

In S912, the building plan summary information acquisition unit overlaps the information (location / lot number) for specifying the land specified in S905 and the brush polygon of the land specified in S905, and is within the writing boundary. The building polygon, which is the information indicating the position of the building in the building, is acquired from the real estate information storage unit 4, and these are transmitted to the local government to acquire the building plan summary information. In the third embodiment, a building record is generated from a building polygon derived based on an aerial photograph or the like, and a building polygon showing a horizontal outline of the building is used when acquiring building plan summary information. However, the building coordinate information acquired by other methods may be used.

It is desirable that the building plan summary information is acquired immediately after the request from the server device 2 to the local government, but it is expected that it will take a certain amount of time to acquire the information. In such a case, for example, information indicating that the building plan summary is being applied for is recorded in the "presence / absence of building plan summary" field of the building record, and the credit evaluation in the client device 3 is suspended. You may do so.

As a modification of the third embodiment, the client device 3 acquires the information for specifying the land from the server device 2 and the building polygon of the land, and based on these, the building plan summary document. The data or document for the acquisition application of information may be output (the information processing system 1 may be provided with a means for outputting the document for the acquisition application of the building plan summary document information). If the digitization of the building plan summary document by the local government has not progressed and the server device 2 cannot be acquired via the network, submit such an acquisition application document to the local government and separately provide the building plan summary document. Is conceivable to acquire. The contents of the acquired building plan summary may be input by the administrator of the server device 2 or the user of the client device 3 and reflected in the building record of the building information storage unit 5. ..

The information processing system 1 of the third embodiment is the same as that of the second embodiment except for the above-mentioned viewpoints, and the description of the same points will be omitted as appropriate. In the information processing system 1 of the third embodiment, the building plan summary information may be uniformly acquired regardless of whether or not the registration information is acquired by the registration information acquisition unit RG. In this case, the information processing system 1 may be uniformly acquired. The location information generation unit PA and the land identification unit LI may not exist in the server device 2.

[others]
In the first embodiment described above, if the building record is not detected using the address information entered by the applicant at the time of contract such as a credit card as a key, it is determined that the address is fictitious and credit is provided. The assessment is getting lower. However, in the second embodiment and the third embodiment, even when the building record is not detected by using the address information as a key, the location information is generated and the land corresponding to the address information is specified and specified. It is intended to acquire registration information and building plan summary information on the land. In the second embodiment and the third embodiment, it is determined that a fictitious non-existent address is input when even the land cannot be specified based on the address information of the applicant.

In addition, in the above-mentioned second embodiment and the third embodiment, a plurality of building registration information and building plan summary information are acquired corresponding to the address information of the applicant, and the address information of the applicant is used. It is also expected that multiple candidates for the corresponding building record will be acquired.

In each of the above embodiments, the land record and the building record are recorded in separate tables, but the present invention is not limited to such an embodiment. For example, the land record and the building record store real estate information. It may be included in a common table held in part 4. In this case, a field for distinguishing a land record and a building record may be provided in the common table. Further, although the information processing system 1 in each of the above embodiments is configured by connecting the server device 2 and the client device 3 via a network, it may be configured by one terminal without going through the network. Further, the server device 2 and the real estate information storage unit 4 may be configured via a network.

In each of the above embodiments, the address information of the applicant is acquired via the client device 3 and inquired by the real estate information storage unit 4 of the server device 2. However, for example, the address information of the applicant is input by a mobile terminal, a PC terminal, an ATM terminal, etc., relayed by the client device 3, and further inquired by the real estate information storage unit 4 of the server device 2, after being inquired. The relayed client device 3 may determine the ownership status, and the result or the like (whether or not a credit card contract can be accepted, etc.) may be provided to the terminal of the applicant to which the address information is input.

It is needless to say that the present invention is not limited to each of the above-described embodiments, and various modifications can be made, and further, each embodiment may be appropriately combined.
