Description

  The present invention relates to a negligence rate estimation system, a negligence rate estimation device, and a negligence rate estimation program for estimating the negligence of a victim or a perpetrator in an accident based on the negligence rate in past accidents.

  An insurance company pays insurance money to a subscriber who has been injured when a subscriber who has taken out non-life insurance has suffered an accident or the like as a victim or perpetrator. The amount of insurance paid by an insurance company to a subscriber varies depending on the non-life insurance plan that the subscriber subscribes to, but may also vary depending on the negligence rate of the subscriber in the accident.

  In an insurance company that deals with such damage, one accident is considered as one case, and the employee who is in charge of each case serves as the contact point, receives the report of the subscriber about the accident, determines the negligence rate, and the subscriber It is common to proceed with work such as paying insurance money. At this time, since the amount of insurance money paid depends on the negligence rate of the subscriber determined by the person in charge, the determination of the negligence rate is important for both the insurance company and the subscriber.

  However, the determination of the negligence rate often depends on the experience and skills of the person in charge, which places a burden on the person in charge. In addition, the person in charge can refer to the negligence ratio of similar cases determined in the past when determining the percentage of negligence, but the person in charge is also responsible for a series of operations to select similar cases for a huge number of past cases. This makes the work of determining the negligence ratio more complicated. Especially for those in charge who have a short experience, the task of determining the negligence rate is considered a heavy burden.

  On the other hand, in the process of creating an accident situation diagram, which is one of the records relating to accidents, a system that appropriately determines the final negligence ratio by increasing / decreasing the negligence ratio is also considered (see Patent Document 1, for example) ).

However, the system of Patent Document 1 also depends on the experience and skills of the person in charge who creates the accident situation diagram.
JP 2005-25667 A

  As described above, the conventional determination of the negligence rate tends to largely depend on the experience and skills of the person in charge who determines the negligence rate of the perpetrator or victim of the accident, etc. There is a problem that the means for assisting the work is not sufficient and the person in charge is forced to bear a burden.

  Accordingly, an object of the present invention is to reduce the burden on the person in charge of determining such a negligence ratio and to facilitate the work of determining the negligence ratio in an accident.

An error rate estimation system having an error rate estimation device that estimates from the error rate of past similar accidents similar to an accident, wherein the client terminal inputs a keyword representing a new accident and uses the keyword as the request A request processing unit that transmits to the negligence rate estimation device; and a display processing unit that displays on the display device the estimation data of the negligence rate received from the negligence rate estimation device in response to the transmitted keyword, and the negligence rate The guessing device includes a keyword indicating a past accident and an error of the perpetrator or victim determined in the past accident. A storage device that stores accident data including a record that correlates a ratio; and an extraction unit that extracts a record including the keyword as data related to a similar accident from the accident data when the keyword transmitted from the client terminal is input; , Classify the accident rate of similar accidents included in each extracted record into groups for each of the predetermined range of fault rates, and generate the distribution rate data as the result of calculating the distribution rate of similar accidents for each group with respect to the overall similar accidents A calculation unit and a transmission unit that transmits the distribution ratio data to the client terminal as the estimated data.

  ADVANTAGE OF THE INVENTION According to this invention, the determination work of the negligence ratio in an accident can be made easy by reducing the burden of the person in charge who determines the negligence ratio.

<Negligence rate estimation system>
As shown in FIG. 1, the negligence ratio estimation system 1 according to the best mode of the present invention is configured such that the negligence ratio estimation apparatus 10 and client terminals 20a to 20c are connected via a network 30 such as an Internet line or an intranet line. Has been.

  The person in charge of the insurance payment related to the accident (case) in which the insurance member becomes the victim or the perpetrator is to estimate the subscriber's negligence rate obtained using this negligence rate estimation system 1 Using the results, the actual negligence rate can be easily determined.

  First, the person in charge uses the client terminals 20a to 20c to input a keyword representing the case in charge (target case). For example, in the negligence ratio estimation system 1, as shown in FIG. 2, items such as “collateral item”, “accident type”, “accident mode”, “accident category”, “accident cause” are targeted this time. A keyword corresponding to the case (target case) is input.

  The client terminals 20a to 20c transmit the input keyword of each item to the negligence rate estimation device 10. The negligence ratio estimation apparatus 10 extracts a case similar to the target case specified by the received keyword (similar case) from the past cases, and transmits the estimation result obtained from the negligence ratio of the similar cases to the client terminals 20a to 20c. To do. Each person in charge determines the negligence rate for the target case with reference to the estimation result provided from the negligence rate estimation device 10.

《Negligence rate estimation device》
As shown in FIG. 1, the negligence ratio estimation device 10 is a computer including a central processing unit (CPU) 11, a storage device 12, and a communication interface (communication I / F) 13. The negligence ratio estimation apparatus 10 transmits data to an external apparatus such as the client terminals 20a to 20c via the network 30 or receives data from the external apparatus under the control of the communication interface 13.

  In the negligence rate estimation device 10, when a negligence rate estimation program (not shown) is installed, an extraction unit 111, a calculation unit 112, a transmission unit 113, and a selection unit 114 are installed in the central processing unit 11 as shown in FIG. Is done.

  The storage device 12 stores accident data D1 as shown in FIG. In addition, the storage device 12 stores intermediate data D2 and distribution ratio data D3 generated by processing executed by the negligence ratio estimation apparatus 10.

  The accident data D1 is data related to past accident cases. As shown in FIG. 3, for example, each record includes “case number” that is the case identifier as a key in each record. “Keywords”, “detailed information” of accidents, and “failure ratio” of insurance subscribers in accidents are associated with each other. In the accident data D1 of FIG. 3, the items corresponding to the “keyword” include “collateral type”, “accident type”, “accident mode”, “accident category”, “accident cause”, and “detailed information”. Information such as “general status” and “progress management”, but is not limited thereto. “Overview” included in “detailed information” is an explanatory text indicating the situation of the accident, and “progress management” is an explanatory text indicating the progress of the processing performed by the insurance company after the accident. .

  In the example shown in FIG. 3, the case with the case number “A123456” guarantees the accident of “objective”, and this accident is a “daily life accident” related to the “back” of “car-to-car”. This is an accident caused by "speed violation". In addition, the negligence rate of insurance subscribers in this case is “80%”.

  The extraction unit 111 inputs the estimation request received from the client terminals 20 a to 20 c by the communication interface 13 via the network 30. This guess request is a request for the client terminals 20a to 20c to request the negligence rate estimation apparatus 10 to transmit data related to the negligence rate of a similar case similar to the target case, and includes keywords for each item related to the target case. It is out.

  The extraction unit 111 that has input the estimation request reads the accident data D1 from the storage device 12, and extracts all records associated with the keywords included in the estimation request from the accident data D1. For example, when “object”, “car-to-car”, “back”, “daily life accident”, and “speed violation” are input as keywords, the extraction unit 111, for example, from the accident data D1 in FIG. The record identified by the case number “A123456” including the keyword is extracted. Since the similar case is a case specified by the same keyword as the target case, the record related to the similar case can be extracted by extracting the record including the keyword of the input target case.

  Further, the extraction unit 111 uses the “keyword” included in the extracted record as a key, and “detailed information” such as an overview of a similar case similar to the target case as shown in FIG. Intermediate data D <b> 2 having a record associated with “case number” is generated and stored in the storage device 12. That is, the intermediate data D2 is a list of similar cases.

  Specifically, the intermediate data D2 in FIG. 4A is generated when keywords “object”, “car-to-car”, “back”, “daily life accident”, and “speed violation” are input. A list of similar cases. The intermediate data in FIG. 4B is a list of similar cases generated when the keywords “vehicle”, “car-to-car”, “side”, “daily life accident”, and “speed violation” are entered. It is.

  The calculation unit 112 reads the intermediate data D2 from the storage device 12, and classifies each case number of the intermediate data D2 into a level corresponding to the negligence ratio. Specifically, the range of the negligence ratio corresponding to each classification level is determined in advance, and the calculation unit 112 classifies each case number of the intermediate data D2 into a group of classification levels corresponding to the negligence ratio. . For example, the case number of similar cases with a negligence ratio of 90% or more is “classification level 1”, the case number of similar cases with 80% or more and less than 90% is “classification level 2”, and the case number of similar cases with 70% or more and less than 80% Case numbers are classified into “classification level 3”, and case numbers of similar cases less than 70% are classified into “classification level 4” groups.

  Further, as shown in an example in FIG. 5, the calculation unit 112 uses the classification result and uses the “classification level” of the negligence ratio as a key, the “fault ratio” corresponding to the classification level, and the classification level. The distribution ratio data D3 that associates the “case number” of the case belonging to the group with the “distribution ratio” of the similar case belonging to the group of the classification level is generated and stored in the storage device 12. Here, the “distribution ratio” is a ratio of similar cases belonging to the group of each classification level among all similar cases included in the intermediate data D2, that is, the number of similar cases belonging to the classification level is determined as the total similar cases. It is obtained by dividing by the number of.

  According to the distribution ratio data D3 in FIG. 5, in the current case, the similar case corresponding to the classification level 1 is “35%”, the similar case corresponding to the classification level 2 is “45%”, and the classification level 3 is applicable. It can be seen that the similar case is “13%” and the similar case corresponding to the classification level 4 is “7%”. Therefore, the negligence ratio of “80% or more and less than 90%” corresponding to “classification level 2” having the highest distribution ratio becomes the negligence ratio estimated by the negligence ratio estimation apparatus 10.

  The transmission unit 113 reads the distribution ratio data D3 from the storage device 12, and transmits it as estimated data to the client terminals 20a to 20c that have transmitted the estimation request via the communication interface 13.

  The selection unit 14 inputs the detailed request received from the client terminals 20 a to 20 c via the network 30 by the communication interface 13. This detailed request is a request in which the client terminals 20a to 20c request the negligence ratio estimation apparatus 10 to transmit detailed data of a desired similar case, and includes the case number of the desired similar case.

  The selection unit 14 that has input the detailed request reads the accident data D1 from the storage device 12, and selects the record identified by the case number included in the detailed request from the accident data D1. The selection unit 14 transmits the detailed information of the selected record as detailed data to the client terminals 20a to 20c that have transmitted the detailed request.

  In this way, the negligence ratio estimation device 10 provides the client terminals 20a to 20c with distribution ratio data D3 relating to the negligence ratio of the past case similar to the current case upon request. Further, the negligence ratio estimation device 10 provides detailed data regarding a specific case to the client terminals 20a to 20c in response to a request.

  In FIG. 1, the negligence ratio estimation apparatus 10 is configured by one computer, but the fault ratio estimation apparatus 10 may be configured by a plurality of computers. Therefore, for example, the accident data D1 may not be stored in the storage device 12 of the negligence ratio estimation device 10, but may be stored in an external storage device.

<Client terminal>
As shown in FIG. 1, the client terminal 20a is a computer including a central processing unit (CPU) 21, an input device 22, a display device 23, a communication interface (communication I / F) 24, and a storage device 25. The input device 22 is a means for a person in charge such as a keyboard or a mouse to input an operation or the like, and the display device 23 is a means for displaying an operation content or a processing content or the like such as a display. In the client terminal 20a, data is transmitted to or received from an external device such as the fault ratio estimation device 10 via the network 30 under the control of the communication interface 24.

  In the client terminal 20a, when a program (not shown) corresponding to the negligence rate estimation system stored in the storage device 25 is installed, as shown in FIG. Part 212 is implemented.

  In the client terminal 20a, in a business related to a new accident (case), the display processing unit 211 reads screen data for displaying an input screen W1 as shown in FIG. indicate. The input screen W1 shown in FIG. 6 includes an input box b5 for inputting keywords regarding the items of “collateral item”, “accident type”, “accident mode”, “accident category”, and “cause of accident”, and execution for operating the execution It has a button b6.

  When an execution button b6 is pressed after a necessary person inputs a required keyword in each of the input boxes b1 to b5 via the input device 22, the request processing unit 212 generates a guess request including the input keyword. The error rate estimation device 10 transmits the error to the error rate estimation device 10 via the communication interface 24. The input screen W1 shown in FIG. 6 is an example in which “object”, “body car”, “back”, “daily life accident”, and “speed violation” are entered as keywords in the input boxes b1 to b5, respectively. .

  Here, an example in which the keyword input by the person in charge is transmitted to the input boxes b1 to b5 of the input screen W1 will be described. However, the keyword list is displayed on the input screen and the selected keyword is transmitted to the person in charge. The same applies to the method.

  When the communication interface 24 receives the estimation data corresponding to the estimation request from the negligence ratio estimation device 10, the display processing unit 211 generates an estimation result screen W2 as shown in FIG. 7 based on the received estimation data. Is displayed on the display device 23. The estimation result screen W2 illustrated in FIG. 7 is an example of a screen displayed based on the estimation data corresponding to the distribution ratio data D3 described above with reference to FIG. The “distribution ratio” in the range of the corresponding negligence ratio is associated with the list of the case numbers of the corresponding negligence ratio cases (“case list”).

  When the person in charge refers to the guess result screen W2 in FIG. 7, the negligence rate of the similar case of the target case is the negligence rate corresponding to “classification level 2”, that is, 80% to less than 90% is 4.5% It can be seen that the error rate estimated by the error rate estimation device 10 is 80% or more and less than 90%. On the other hand, each similar case has the same target case and keyword, but has different “general conditions”, “progress management” and the like that cannot be grasped from the estimation result screen W2. Therefore, the person in charge can finally determine the negligence ratio with reference to the “summary” and “business management” of the similar case together with the estimated negligence ratio.

  When any case number included in the estimation result screen W2 is selected by the person in charge via the input device 22, the request processing unit 212 generates a detailed request including the selected case number, and sets the communication interface 24. To the negligence rate estimation apparatus 10 via the network. For example, when the case number “A123456” is selected in the estimation result screen W2 of FIG. 7, the request processing unit 212 transmits a detailed request including the selected case number “A123456”.

  When the communication interface 24 receives the detailed data corresponding to the detailed request from the negligence ratio estimation device 10, the display processing unit 211 generates a detailed screen W3 as shown in FIG. 8 based on the received detailed data, and the display device 23. The detailed screen W3 shown in FIG. 8 includes “overview” and “business management” included in the detailed data.

  In addition, if the person in charge wants to determine the negligence rate of the target case with reference to the outline of other similar cases, the other person can select the other case number included in the estimation result screen W2, and With reference to the general situation, the negligence rate of the target case can be determined.

  As described above, the client terminal 20a transmits the keyword related to the input target case to the negligence ratio estimation apparatus 10, and receives and displays the negligence ratio estimated according to the transmitted keyword. Further, the client terminal 20a receives and displays detailed information on similar cases received from the negligence rate estimation device in response to a request.

  Since the client terminals 20b and 20c have the same configuration as the client terminal 20a, the description thereof is omitted. Further, in the negligence ratio estimation system 1 illustrated in FIG. 1, the configuration is described in which three client terminals are connected to the network 30, but the number of connected client terminals is not limited.

<Negligence rate estimation method>

  Further, the extraction unit 111 stores the data of all the records extracted in step S3 in the storage device 12 as the intermediate data D2 (S4).

  When the intermediate data D2 is stored in the storage device 12, the calculation unit 112 classifies similar cases for each classification level corresponding to the negligence ratio included in each record of the intermediate data D2, and the similarity in each classified classification level. The distribution ratio of cases is calculated (S5).

  Moreover, the calculating part 112 memorize | stores the calculation result of step S5 in the memory | storage device 12 as distribution ratio data D3 (S6).

  Thereafter, the transmission unit 113 reads the distribution ratio data D3 from the storage device 12 and transmits it to the client terminal 20a (S7).

  The display processing unit 211 of the client terminal 20a that has received the distribution ratio data D3 in step S7 displays the received estimation data on the display device 23 as an estimation result screen W2 as shown in FIG. 7 (S8).

  The person in charge who uses the client terminal 20a selects the case number in the guess result screen W2 when he wants to know detailed information about the similar case included in the guess result screen W2.

  When any case number included in the estimation result screen W2 is selected by the person in charge via the input device 22 (S9), the request processing unit 212 selects the case number selected in step S9 for the negligence rate estimation device 10. A detailed request including the message is transmitted (S10).

  The selection unit 114 of the negligence ratio estimation device 10 that has received the detailed request in step S10 reads the accident data D1 from the storage device 12, and selects a record associated with the case number included in the received detailed request (S11).

  Further, the selection unit 114 transmits the data of the record selected in step S11 to the client terminal 20a as detailed data (S12).

  Upon receiving the detailed data in step S12, the display processing unit 211 of the client terminal 20a displays the received detailed data on the display device 23 as a detailed screen W3 as shown in FIG. 8 (S13).

  The person in charge can grasp the contents of past similar cases by referring to the detailed screen W3 displayed on the display device 23 in this way, and can determine the negligence ratio of the current case. If another case number is selected, the detail request is sent again and a new detail screen W3 is displayed. The person in charge determines the negligence ratio of the current case with reference to a plurality of similar cases. can do.

  In addition, in FIG. 9, although demonstrated as a process with the negligence ratio estimation apparatus 10 and the client terminal 20a, it is the same even if it replaces the client terminal 20a with the client terminals 20b and 20c.

  As described above, in the negligence rate estimation system 1, each person in charge who determines the negligence rate with respect to a case inputs a keyword via the client terminals 20a to 20c, so that the negligence rate estimation device 10 responds to a similar case. The negligence ratio estimated based on the negligence ratio determined in the above can be received. Therefore, the person in charge can determine the negligence ratio of the current case with reference to the negligence ratio estimated by the negligence ratio estimation apparatus 10. In addition, since the person in charge can easily refer to the detailed information of the similar case, it is possible to determine an appropriate negligence ratio.

  In the example described above with reference to FIGS. 1 to 9, keywords are input and displayed on the client terminals 20 a to 20 c having the input device 22 and the display device 23, but the negligence ratio estimation device 10 itself is also an input device.
