Description

The present invention relates to a vacant house determining device, a vacant house determining method, and a vacant house determining program that determine whether a house is vacant based on an address.

In recent years, e-commerce businesses that conduct non-face-to-face financial transactions perform customer authentication when a customer requests to open an account. Patent Document 1 discloses an account opening support method that uses personal authentication to support account opening.

Patent No. 5922194

By the way, one method of identity authentication by such e-commerce businesses is to accept the input of an address from the user, and then actually send a document containing authentication information to that address, and the user can enter the document with the authentication information. Some devices authenticate your identity by entering the authentication information listed on the website. However, at this time, although it is a real address, the user registers a false address as a mere recipient of a document that does not belong to him/herself, receives the document in front of that address, performs authentication, and completes user registration. The problem was that it was possible. In this case, even if the user makes a malicious transaction, there is a problem that the user may not be able to be traced back to the user himself later.

<Configuration>
The vacant house determination device 100 is a computer device implemented by a PC, a server device, or the like. FIG. 2 is a block diagram showing a configuration example of the vacant house determination device 100. As shown in FIG. 2, the vacant house determination device 100 includes a communication section 110, a storage section 120, and a control section 130. Further, the vacant house determination device 100 may include an input section 140 and a display section 150. Each unit of the vacant house determination device 100 (the communication unit 110, the storage unit 120, the control unit 130, the input unit 140, and the display unit 150) are connected to each other via a bus B so as to be able to communicate with each other.

The communication unit 110 is a communication interface that has a function of communicating with other devices via the network 300. The communication unit 110 does not require wired or wireless communication as long as it can communicate with other devices, and may perform wired or wireless communication, or both. Furthermore, the communication unit 110 may use any communication standard for communication as long as it can communicate with other devices. In this embodiment, communication unit 110 receives inquiry information 10 from terminal device 200 and transmits it to control unit 130. Furthermore, in accordance with instructions from the control unit 130, the communication unit 110 transmits, to the terminal device 200 that has transmitted the inquiry information 10, vacant house information 11 that allows estimation of whether or not the house is vacant.

The storage unit 120 is a storage medium that has a function of storing various programs and data necessary for operation of the vacant house determination device 100. The storage unit 120 can be realized by various storage media such as, for example, an HDD (Hard Disc Drive), an SSD (Solid State Drive), and a flash memory, but is not limited to these. The program stored in the storage unit 120 includes information about whether electricity is being supplied to the address, or, if electricity is not being supplied, how to stop (discontinue) the supply of electricity, based on the address. There are programs for identifying abolition methods and estimation programs for estimating whether the house corresponding to the address of the inquiry is vacant based on the specified method of stopping (abolition) the supply of electricity. The storage unit 120 also stores abolition information 121 for specifying a method of discontinuing power supply from an address, vigilance point information 122a to 122d for specifying a vigilance point from a method of discontinuing power supply, and information on vigilance points. It also stores vacant house standard information 123 for specifying the probability that the house is vacant. Details of the abolition information 121, warning point information 122a-122d, and vacant house standard information 123 will be described later.

The control unit 130 is a processor that implements various functions that should be implemented by the vacant house determination device 100 by executing various programs stored in the storage unit 120. The control unit 130 extracts address information from the inquiry information transmitted from the communication unit 110 and transmits the extracted address information to the identification unit 131. The control unit 130 includes a specifying unit 131, an estimating unit 132, and an output control unit 133.

The specifying unit 131 refers to the discontinuation information 121 from the transmitted address information, and specifies whether or not the corresponding electric power is supplied, and the method for discontinuing the supply of electric power if the electric power is not supplied. Then, the specifying unit 131 transmits the specified method of discontinuing the supply of electric power to the estimating unit 132.

The estimating unit 132 refers to the alert point information 122a to 122d and identifies the corresponding alert point based on the method of discontinuing the power supply transmitted from the specifying unit 131. A warning point is a point used to estimate whether a house at a corresponding address is vacant or not. The estimating unit 132 refers to the warning point information 122a based on the information indicating the manner in which the power supply is to be discontinued, and specifies a warning point for the manner in which the power supply is to be discontinued. Then, based on the identified warning points, the estimation unit 132 refers to the vacant house standard information 123 to estimate the possibility that the house corresponding to the address is vacant, and sends information on this possibility to the output control unit 133. introduce.

The output control unit 133 generates vacant house information based on the probability that the house is vacant estimated by the estimation unit 132, and transmits the generated vacant house information to the terminal device 200 that has transmitted the inquiry information via the communication unit 110. do.

Although not shown, the control unit 130 accepts input from the operator of the vacant house determination device 100 of a threshold value for the warning point in the vacant house standard information 123 for determining whether the house is vacant according to the warning point, and sets the threshold value. It may also include a setting section for changing.

The input unit 140 is an interface that has a function of receiving input from the operator of the vacant house determination device 100. The input unit 140 can be realized by, for example, a keyboard, a touch panel in combination with the display unit 150, etc., but is not limited to these. For example, when the operator of the vacant house determination device 100 receives an address from the operator 20 of the terminal device 200 by telephone or the like, the input unit 140 can accept the input of the address and transmit it to the control unit 130. can. Alternatively, the input unit 140 may receive an input for setting a threshold value, which is a criterion for determining whether the house corresponding to the address is vacant, and transmit the input to the control unit 130.

The display unit 150 is a monitor that has a function of displaying data instructed by the control unit 130. The display unit 150 may display, for example, the vacant house information generated by the output control unit 133 in the form of text or images.

The above is the configuration of the vacant house determination device 100.

Note that the terminal device 200 of the operator 20 making the inquiry may be any information processing device represented by a commonly known PC, tablet terminal, smartphone, etc., and may have the same configuration as a general terminal. A detailed description of the configuration will be omitted.

<Data>
From here, various data used by the vacant house determination device 100 will be explained.

FIG. 3 is a data conceptual diagram showing an example of the data structure of the obsolescence information 121. As shown in FIG. 3, the abolition information 121 is information in which address information 301 and abolition information 302 are associated with each other. Further, the abolition information 302 includes power supply presence/absence 321 at the corresponding address, a discontinuation method 322, a discontinuation date 323, the number of inquiries 324, and a housing type 325. The obsolescence information 121 is updated by the operator of the vacant house determination device 100 one after another. Alternatively, the vacant house determination device 100 may include an update unit that receives input of various information regarding the stoppage of power supply from a business operator or the like who performed the electrical work that caused the power supply to be stopped, and updates the abolition information 121. .

The power supply presence/absence 321 indicates whether or not power is currently being supplied to the house indicated by the corresponding address (including a house in an apartment complex, a company building, a commercial facility, etc.). This is the information shown. If the power supply presence/absence 321 is "Yes", it means that power is being supplied, so the vacant house information 11 as a response to the inquiry as to whether the address is a vacant house indicates that it is not a vacant house. It will show information. On the other hand, when the power supply presence/absence 321 is "absent", the estimation unit 132 performs estimation processing to determine whether the house is vacant.

The discontinuance method 322 is information indicating in what manner the power supply was stopped when the power supply was stopped. There are five types of abolition methods 322: (1) breaker off, (2) switch off, (3) secondary side processing off, (4) disconnection, and (5) removal. In the order of (1) to (5), the probability that the house is vacant increases in ascending order. This is because the latter requires more effort to resupply electricity, so it is less likely that people will live there. Therefore, by using the abolition method 322, it is possible to estimate the possibility that the house at the address is vacant.

Breaker off refers to the generally recognized process of turning off a so-called breaker switch. A breaker is generally a device that automatically shuts off a circuit when more than a certain amount of electricity is used or an abnormal current flows, but when the breaker is turned off, It is possible to disable the use of electricity. This can be said to be the easiest method to stop the power supply.

Switch off refers to turning off a switch (switching unit, etc.), which is a device that opens and closes an electric circuit (electricity flow path) in a metering device such as a smart meter. A switch is installed between the breaker and the power supply source (a transformer that transforms high-voltage alternating current into household power), and when the switch is turned off, it prevents power from reaching the breaker. can.

Secondary side processing off is a process of physically disconnecting the house side wiring connected to the metering device from the meter and cutting off the electricity supply.

Disconnection refers to physically cutting off the wiring from utility poles, etc. in the vicinity of a house that was supplying electricity. Generally speaking, it is sometimes called pole-cutting because the wiring from the pole is cut.

Removal refers to the removal of the power equipment itself from the house that was supplying power. In the case of disconnection, it is possible to restore power as long as the wiring is installed, but in the case of removal, more steps are required, such as relocating the power equipment, so it is necessary to supply power to such an address. Since this possibility is low, it can be said that there is a high possibility that the house can be estimated to be vacant.

The discontinuation date 323 is information indicating the date on which power supply was stopped. The abolition date 323 is used to determine whether the house is vacant or not, depending on the number of days that have passed from the abolition date to the present. The longer the number of days that have passed since the power supply was cut off, the more likely the house is to be vacant. Therefore, by using the abolishment date 323, which can calculate the number of days since the power supply was stopped, it is possible to estimate whether the house at the address is vacant.

The number of inquiries 324 is information indicating the number of times the address indicated by the address is used for inquiries as to whether or not the house is vacant. The number of inquiries 324 may be the total number of inquiries up to the present, or may be the total number of inquiries over a predetermined period (for example, 10 years) from the present to the past. Generally speaking, the number of inquiries will not be that high, but if the address is being misused for some reason, there is a possibility that the address will be used more than usual. Therefore, by using the number of inquiries 324, it is possible to estimate whether or not the house corresponding to the address is vacant, or more precisely, whether or not there is a possibility that the address is being misused.

The housing aspect 325 is information indicating whether the aspect of the corresponding house is one house in an apartment complex or a detached house. It can be said that detached houses that have long been uninhabited are easier to use for things such as receiving packages as mentioned above. Therefore, assuming such a case, it can be said that the probability that the house corresponding to the address of the inquiry is vacant is higher for a detached house than for an apartment complex where there is a high possibility of being seen by others, so the housing type 325 is used. By doing so, it is possible to estimate whether the house corresponding to the address is vacant or not.

In the example shown in FIG. 3, as an example, for a house whose address information 301 is "Izumisano City, Osaka Prefecture...", as shown in the power supply presence/absence 321, the power supply is "no". The abolition method 322 is "Switch off", the abolition date 323 is "June 23, 2019", the number of inquiries 324 is "15 times", and the housing type 325 is "single-family house". I can understand something.

FIG. 4 is a data conceptual diagram showing an example of the data structure of the warning point information 122 (122a to 122d). FIG. 4(a) shows warning point information 122a for the method of abolishing the power supply, FIG. 4(b) shows warning point information 122b for the number of days elapsed from the date of abolishment, and FIG. 4(c) shows the address 4(d) shows vigilance point information 122d for the housing type. That is, each piece of warning point information 122 is information that numerically indicates a warning point for estimating the possibility that the house is vacant.

As shown in FIG. 4A, the vigilance point information 122a is information in which the abolition method 411 is associated with the vigilance point 412.

The abolition method 411 is information indicating in what manner the power supply was stopped when the power supply was stopped, and is the same information as the above-mentioned abolition method 322.

The warning point 412 is information indicating the first warning point P1 to be set for the address when the power supply is stopped by the corresponding abolition method 411.

The abolition method 322 to which the address indicated by the inquiry information 10 corresponds is specified, and the vigilance point associated with the abolition method 411 to which the abolition method 322 corresponds becomes the first vigilance point P1.

In the example shown in FIG. 4A, it can be understood that when the abolition method 411 is "turn off the switch", the warning point 412 is "2".

The warning point information 122b shown in FIG. 4(b) is information in which the abolishment date 421 and the warning points 422 are associated with each other.

The discontinuation date 421 is information indicating the period during which the supply of electricity was stopped, and is information for specifying within which period the date when the supply of electricity was stopped from the date of the inquiry. It is.

The warning point 422 is information indicating the second warning point P2 when the date on which the power supply to the inquired address is stopped falls within the period of the abolishment date 421.

For the address indicated in the inquiry information 10, the abolition date 323 when the power supply was cut off is specified, the period to which the abolition date 323 corresponds is specified from the abolition date 421, and the period corresponding to the abolition date 421 is associated with the specified abolition date 421. The vigilance point that is present becomes the second vigilance point P2.

In the example shown in FIG. 4(b), as an example, the discontinuation date 421 is "1 year or more and less than 2 years", that is, one year has passed since the power supply stopped, but two years have passed since the power supply stopped. It can be understood that the warning point 422 is "3" when the time has not passed.

Next, the warning point information 122c shown in FIG. 4(c) is information in which the number of times of matching 431 and the warning points 432 are associated with each other.

The number of times of verification 431 is information indicating the number of times inquiries have been made in the past as to whether or not the house indicated by the address is vacant. The number of verifications 431 corresponds to the number of inquiries 324 described above.

The vigilance point 432 is information indicating the third vigilance point P3 of the corresponding verification count 431.

In the example shown in FIG. 4(c), it can be understood that if the number of verifications is "2 to 5", the warning point is "2", for example.

The warning point information 122d shown in FIG. 4(d) is information in which a housing style 441 and a warning point 442 are associated with each other.

The housing type 441 is information indicating the type of house at the address indicated by the inquiry information 10, and indicates whether it is an apartment complex or a detached house. The housing aspect 441 is information corresponding to the housing aspect 325 described above.

The warning point 442 is information indicating the fourth warning point P4 according to the corresponding housing type 441.

In the example shown in FIG. 4D, it can be understood that, for example, if the housing type is "apartment housing", the warning point 442 is "1".

By holding the respective warning point information 122a to 122d shown in FIG. 4, the vacant house determination device 100 can specify the warning point according to the state of discontinuation of power supply.

FIG. 5 is a data conceptual diagram showing an example of the data structure of the vacant house reference information 123. The vacant house reference information 123 shown in FIG. 5 is information used by the estimation unit 132 to estimate the possibility that the house is vacant based on the calculated warning points.

FIG. 5A is a data conceptual diagram showing an example of the structure of the vacant house standard information 123. FIG. 5(b) is a data conceptual diagram showing an example of the configuration of the vacant house reference information 123 configured in a manner different from that of FIG. 5(a). FIG. 5(c) is a data conceptual diagram showing an example of the configuration of the vacant house reference information 123 configured in a manner different from FIGS. 5(a) and 5(b).

The vacant house standard information 123a shown in FIG. 5(a) is information in which the total warning points 501 and the vacant house probability 502a are associated with each other.

The total vigilance points 501 is information indicating the range of the total vigilance points for comparison with the total vigilance points determined based on the state associated with the obsolescence information derived from the address.

The vacant house probability 502 is information indicating the probability that the house is vacant when the calculated total vigilance points fall within the range of the corresponding total vigilance points 501, expressed as high, medium or low.

In the example of FIG. 5(a), if the total number of warning points is "4", the vacant house probability is "low" since it falls within the range of "0 to 6".

The vacant house standard information 123b shown in FIG. 5(b) is information in which the total warning points 511 and the vacant house probability 512 are associated with each other.

The total vigilance points 511 is information indicating the range of the total vigilance points for comparison with the total vigilance points determined based on the state associated with the obsolescence information derived from the address.

The vacant house probability 512 is information that indicates the probability that the house is vacant when the calculated total vigilance points fall within the range of the corresponding total vigilance points 511, expressed as a percentage.

In the example of FIG. 5(b), if the total number of warning points is "4", it falls within the range of "4 to 6", so the probability of vacant house is "20%".

The vacant house standard information 123c shown in FIG. 5(c) is information in which the total warning points 521 and the vacant house probability 522 are associated with each other.

The total vigilance points 521 is information indicating the range of the total vigilance points for comparison with the total vigilance points determined from the state associated with the obsolete curse derived from the address.

The vacant house probability 522 is information expressing the possibility that the house is vacant when the calculated total vigilance points fall within the range of the corresponding total vigilance points 521, based on whether or not the house is vacant.

In the example of FIG. 5(c), if the total number of warning points is "4", it falls within the range of "0 to 7", so it can be understood that the vacant house probability is "none".

The vacant house determination device 100 stores any of the vacant house standard information 123 shown in FIGS. 5(a) to 5(c), and refers to the stored vacant house standard information 123 to determine whether the house is vacant or Information indicating the possibility that the house is vacant can be transmitted to the terminal device 200 that made the inquiry. Note that the vacant house determination device 100 may be configured to store all the vacant house standard information 123 and select the vacant house standard information to be used as appropriate. Further, the range of the total warning points may be changed to an appropriate range depending on the type and number of obsolete information used for calculation.

<Operation>
The operation of the vacant house determination device 100 will be described below. FIG. 6 is a sequence diagram showing an example of exchange between the vacant house determination device 100 in the communication system 1 and the terminal device 200 that makes an inquiry.

As shown in FIG. 6, the operator 20 uses his own terminal device 200 to transmit inquiry information 10 including the address to the vacant house determination device 100 (step S601). For example, when the operator 20 receives a user registration request for a service from a general user, the operator 20 inputs the address transmitted from the general user into the terminal device 200. Then, the terminal device 200 transmits the inquiry information 10 including the address input to the terminal device 200 to the vacant house determination device 100 in accordance with the input from the operator 20.

The vacant house determination device 100 calculates a warning point based on the address included in the received inquiry information 10 (step S602). Based on the calculated warning points, the vacant house determination device 100 identifies the vacant house probability indicating the possibility that the house at the address included in the inquiry information 10 is vacant (step S603). The vacant house determination device 100 transmits the specified vacant house probability to the terminal device 200 that transmitted the inquiry information 10 (step S604).

The terminal device 200 receives the information including the vacant house probability transmitted from the vacant house determination device 100, displays the information indicating the vacant house probability (step S605), and ends the process.

Next, an example of the operation of the vacant house determination device 100 in the communication system 1 will be described using FIG. 7. FIG. 7 is a flowchart showing the operation of the vacant house determination device 100 for realizing the exchange shown in FIG. 6.

As shown in FIG. 7, the communication unit 110 of the vacant house determination device 100 receives inquiry information 10 transmitted from the terminal device 200 (step S701). The communication unit 110 transmits the received inquiry information 10 to the control unit 130.

The control unit 130 extracts address information from the transmitted inquiry information 10. Then, it is determined whether or not electricity is being supplied to the house indicated by the extracted address, with reference to the electricity supply presence/absence 321 of the abolition information 121 (step S702).

If the control unit 130 determines that power is not being supplied to the house at the address indicated in the inquiry information (NO in step S702), the specifying unit 131 of the control unit 130 determines that electricity is not supplied to the house at the address indicated in the inquiry information 10. The abolition method corresponding to the above is specified from the abolition method 322 of the abolition information 121 (step S703). Then, from the identified abolition method, the corresponding warning point P1 is specified by referring to the warning point information 122a (step S704).

Next, the specifying unit 131 identifies the abolishment date on which the supply of electricity to the house indicated by the address in the inquiry information 10 was stopped from the abolishment date 323 in the abolishment information 121. Then, specify how many days from now the specified abolition date is within. Then, the number of days from the present date to which the specified abolition date is within is specified by referring to the abolition date 421 of the warning point information 122b. (Step S705). The specifying unit 131 then specifies the corresponding vigilance point P2 from the specified obsolescence date 421 (step S706).

Next, the identification unit 131 identifies the number of inquiries corresponding to the address in the inquiry information 10 from the number of inquiries 324 in the obsolescence information 121 (step S707). Then, it is determined which of the ranges indicated by the number of collations 431 of the vigilance point information 122c falls within the specified number of inquiries, and the corresponding vigilance point P3 is specified (step S708).

Further, the specifying unit 131 specifies the housing type of the house indicated by the address in the inquiry information 10 from the housing type 325 in the abolishment information 121 (step S709).

Then, from the specified housing type, the warning point information 122d is examined to specify the warning point P4 (step S710).

The estimating unit 132 totalizes each warning point P1 to P4 specified by the specifying unit (step S711). Then, the estimating unit 132 specifies to which range of the total warning points of the vacant house standard information 123 the total warning point total falls. Then, the vacant house probability 502 associated with the specified range is specified (step S712). The estimation unit 132 transmits the specified vacant house probability to the output control unit 133 as information indicating the possibility that the address is a vacant house.

The output control unit 133 generates vacant house information 11 based on the transmitted information indicating the possibility that the house is vacant, and transmits the generated vacant house information 11 to the terminal device 200 via the communication unit 110 (step S713), the process ends.

On the other hand, if the control unit 130 determines that electricity is being supplied to the house at the address indicated by the inquiry information (YES in step S702), the specifying unit 131 of the control unit 130 Since there is a resident in the house, the vacant house probability is set to zero, that is, 0 (step S714). The specifying unit 131 transmits the specified vacant house probability to the output control unit 133. The output control unit 133 generates vacant house information 11 indicating whether the house is vacant or the probability is 0 based on the transmitted vacant house probability, and transmits the generated vacant house information 11 to the terminal device via the communication unit 110. 200 (step S715), and the process ends.

In the process shown in FIG. 7, the processes shown as a set of steps S703 and S704, a set of steps S705 and S706, a set of steps S707 and S708, and a set of steps S709 and S710 are executed in the order of execution. can be changed from the order shown in FIG. 7, or may be executed in parallel. For example, the processing from steps S703 to S710 may be executed in the order of S705-S706, S709-S710, S703-S704, and S707-S708.

<Summary>
As shown in the above embodiment, the vacant house determination device 100 receives address information and identifies whether the house corresponding to the address is vacant based on the method of discontinuing the supply of electricity to the house. When the power supply is cut off, it is possible to estimate whether there is a high possibility that people will live in the house in the future, depending on the method of decommissioning, and this can be used as a basis for estimating the possibility that the house is vacant. Then, by outputting the vacant house information 11 indicating the possibility that the vacant house determination device 100 is vacant, the terminal device 200 allows the user to This can be used as a basis for deciding whether to register or not, and it is possible to improve the possibility of preventing malicious users from registering.

<Supplement>
It goes without saying that the apparatus according to the embodiment described above is not limited to the embodiment described above, and may be realized by other methods. Various modifications will be described below.

(1) In the above embodiment, the vacant house determination device 100 refers to the abolition information 121, the warning point information 122a to 122d, and the vacant house standard information 123, and determines that the address indicated by the inquiry information is a vacant house. We decided to determine whether or not. However, the method for determining whether the address indicated by the inquiry information is a vacant house is not limited to the method shown in the above embodiment. This can also be achieved by the following method.

For example, instead of the information shown in FIGS. 3 to 5, the vacant house determination device 100 includes various pieces of information (abolition method, abolition date, number of times of verification, housing type) indicating the mode of discontinuation of electricity supply corresponding to the address, A learning model that has learned the correspondence between whether or not the house is vacant may be stored in the storage unit 120. Then, the estimating unit 132 may be configured to input the address indicated by the inquiry information 10 to the learning model, acquire information on the possibility that the house is vacant, and transmit it to the output control unit 133. .

The learning model includes at least one of the following information as information indicating the mode of discontinuation of electricity supply: discontinuation method, date of discontinuation, number of verifications, and housing type; and information indicating whether the house is vacant in that case; It can be constructed by learning by using information that associates these as training data. As the learning model algorithm, an appropriate one may be selected from existing algorithms and used. In this way, the estimation unit 132 may be configured to perform estimation using deep learning.

(2) In the embodiment described above, the vacant house determination device 100 further includes a learning unit that learns the threshold value that defines the range of warning points in the vacant house standard information 123 (123a-123c) and automatically changes the setting. You can also use it as For example, the learning unit may receive feedback information indicating whether or not the house is actually vacant based on the result estimated by the estimation unit 132 of the vacant house determination device 100, and change the threshold value based on the received feedback information. good.

For example, for a result in which the calculated total alert point is "7", when determined using the vacant house standard information 123 shown in FIG. 5(a), the vacant house probability 502 becomes "medium". On the other hand, as a result of accumulating feedback information, if a predetermined number of feedback information has been accumulated indicating that the house is vacant when the total warning points are "7", or if the house is vacant when the total warning points are "7". Qualitatively, it is sufficient to estimate that the total number of warning points is ``7'' is a vacant house, such as when the feedback information that the house has a total of 7 warning points is more than a predetermined number than the feedback information that the house is not vacant. , the learning unit sets the range of the total warning points corresponding to the empty house probability 502 of the vacant house standard information 123a being “low” from “0 to 6” to “0 to 7”. The range of the total warning points corresponding to the "medium" vacant house probability 502 may be changed from "7 to 10" to "8 to 10."

By including such a learning unit, the vacant house determination device 100 can sequentially set an appropriate range of the total warning points and specify the vacant house probability. The timing of the change by the learning unit may be periodically executed, or may be determined based on a predetermined condition (for example, in the above example, the feedback information has a total of 7 warning points and the house is vacant). The feedback information may be executed when the timing exceeds the number of pieces of feedback information that has a total warning point of "7" and that the house is not vacant, etc.).

(3) In the embodiment described above, the estimating unit 132 totals the identified vigilance points P1 to P4, that is, P1+P2+P3+P4, as the total vigilance point, but this is not the case. Each warning point may be multiplied by a predetermined coefficient. In other words, points that are likely to contribute to the determination of whether a house is vacant are multiplied by a relatively high coefficient, and points that are unlikely to contribute are multiplied by a lower coefficient. The total caution points may be calculated by multiplying by . That is, the estimation unit 132 may calculate αP1 + βP2 + γP3 + δP4 as the total warning points. Here, α, β, γ, and δ are coefficients having values of 0 or more, and may be appropriately set by the operator of the vacant house determination device 100 or the like.

Furthermore, the vacant house determination device 100 may include a coefficient learning unit that determines the suitability of these values and resets them so that appropriate values can be set for these coefficients α, β, γ, and δ. For example, the coefficient learning unit receives feedback information as shown in supplement (2) above, and adjusts and learns the coefficients so that all the feedback information results in the results indicated by the feedback information. may be used as

(4) In the above embodiment, an example of using the method of discontinuing electricity supply, the number of days that have passed since the discontinuation date, the number of inquiries as to whether the address is vacant, the type of housing, etc. is shown as an example of the discontinuation information. However, the obsolescence information is not limited to these. Other information may also be used. This will be explained in detail below.

FIG. 8 is a diagram showing another example of obsolescence information. As shown in FIG. 8, the abolition information 121 may be information in which surrounding abolition status 326, area attribute 327, site area 328, and building age 329 are stored for each address. The obsolescence information 121 may include all of the information shown in FIG. 3 and the information shown in FIG. 8, or may hold only a part of them. Further, even if all of the information is included, the vacant house determination device 100 may be configured to select necessary information as appropriate, or the operator of the vacant house determination device 100 may set necessary information as appropriate. It may be configured as follows.

The surrounding abolition status 326 is information indicating whether or not the supply of electricity has been discontinued to houses corresponding to addresses surrounding the corresponding address. In the example shown in FIG. 8, the surrounding abolition status 326 is defined in three stages: "no abolition," "less abolition," and "many abolition," but it is expressed by the number of abolitions of electricity supply. Good too. Further, the surrounding addresses may be any addresses that exist around the target address, and may be only the house next to the corresponding address, or may include the three houses opposite the address in addition to the neighboring house. Alternatively, the surrounding addresses may be addresses of houses located within a predetermined distance from the target address.

The area attribute 327 is information indicating whether there is public housing such as prefectural housing or municipal housing at the target address. The area attribute 327 is shown as an example in which public housing is defined in three levels: "few," "normal," and "many," but it may also be expressed by the number of public housing.

The site area 328 indicates the site area of the corresponding address. Since the type of house (for example, whether it is a detached house or not) can be specified from the site area, the possibility that the house is vacant can be estimated from the contents.

The building age 329 is information indicating the number of years that have passed since the corresponding address was built.

By using this information and the warning point information shown in FIG. 9, the warning points of each address can be calculated. FIG. 9A shows warning point information 122e in which a warning point 452 is associated with a surrounding abolition status 451 indicating whether power supply around the target address has been abolished.

The surrounding abolition status 451 is information indicating the abolition status of the vicinity of the target address. The warning point 452 is information indicating the fifth warning point P5 when the surrounding abolition status of the inquired address corresponds to any of the surrounding abolition situations 451.

In the example shown in FIG. 9A, it can be seen that when the peripheral abolition status 451 is "less abolition", the warning point is "2". If the power supply to nearby residences has been discontinued, there is a high possibility that the surrounding area is uninhabited, so it is possible to receive letters, packages, etc. at the target address without being seen by others. It can be said that the possibility of this happening increases, so the caution points are set accordingly.

The vigilance point information 122f shown in FIG. 9(b) is information in which an area attribute 461 including a target address and a vigilance point 462 are associated with each other.

The area attribute 461 including the target address is information indicating the number of public housing units in a predetermined area including the address. Here, the predetermined area may be within a predetermined range, or may be an area within a predetermined range centered on the target address. The predetermined range may be, for example, an administrative district. The warning point 462 is information indicating the sixth warning point P6, which corresponds to the area attribute of the inquired address.

In the example shown in FIG. 9(b), it can be understood that when the area attribute 461 is "many public housing", the warning point is "3". Note that warning points depending on area attributes may be determined depending on the region. For example, in some areas, the warning points may be set low even in areas where there are many public housing units, and in other areas, the warning points may be set low even in areas where there are many public housing units. It is also possible to set it high. For example, in areas where public housing is scheduled for demolition and left behind, there is a high possibility that the houses will be vacant, so the warning points should be set high, and if the public housing is popular, people will Since there are many houses, it is unlikely that the house is vacant, so set the alert point low.

The warning point information 122g shown in FIG. 9(c) is information in which the site area 471 of the target address and the warning points 472 are associated with each other. The wider the target site area, the higher the possibility that it is a detached house, so the seventh warning point P7 is set to be higher. In the example shown in FIG. 9(c), it can be understood that when the site area 471 is "20 to 30 m ² ", the warning point is "4".

The warning point information 122h shown in FIG. 9(d) is information in which the building age 481 of the residence at the target address is associated with the warning point 482 thereof. The longer the residence at the target address was built, the older the residence, and the higher the probability that the residence will become vacant. Therefore, the warning point information 122h is set so that the longer the age of the target building, the higher the large 8 warning points P8. In the example shown in FIG. 9(d), it can be understood that when the building age is "5 years or more and less than 10 years", the warning point is "3".

Using the information shown in FIGS. 8 and 9, the identifying unit 131 can identify the warning points according to each piece of abolition information, and the estimating unit 132 can also Similarly, it is possible to estimate whether the target address is a vacant house based on the identified warning points.

(5) In the above embodiment, as a method for estimating whether the house corresponding to the address in the vacant house determination device is vacant, the processor of the device executes the above-mentioned specific program, estimation program, etc. It is estimated whether the house corresponding to the address is vacant or not, but this is based on the logic circuit (hardware) formed in the device such as an integrated circuit (IC (Integrated Circuit) chip, LSI (Large Scale Integration)), etc. It may also be realized by a dedicated circuit. Further, these circuits may be realized by one or more integrated circuits, and the functions of the plurality of functional units shown in the above embodiments may be realized by one integrated circuit. LSI is sometimes called VLSI, super LSI, ultra LSI, etc. depending on the degree of integration.

Further, the above program may be recorded on a recording medium readable by a processor, and the recording medium may be a "non-temporary tangible medium" such as a tape, a disk, a card, a semiconductor memory, a programmable logic circuit, etc. can be used. Further, the program may be supplied to the processor via any transmission medium (communication network, broadcast wave, etc.) that can transmit the program. The present invention can also be realized in the form of a data signal embedded in a carrier wave, in which the walking teaching program is embodied by electronic transmission.

Note that the above program may be implemented using, for example, a compiled language such as C language, a script language such as C++, ActionScript, or JavaScript (registered trademark), an object-oriented programming language such as Objective-C or Java (registered trademark), or a markup language such as HTML5. It can be implemented using any language, but is not limited to these languages.
