The intermediary system includes an information processing terminal related to an exhibitor, an information processing terminal related to a purchase applicant, and an information processing server related to the intermediary system, in a communicable manner. The information processing server related to the intermediary system causes the information terminal related to the exhibitor and/or the information terminal related to the purchase applicant to display a value as an equilibrium price where demand and supply match, a market price which is equivalent to the store price of a property seller, and the listing price of the property in consumer-to-consumer transactions in order to give a sense of satisfaction to both the exhibitor and the purchase applicant.SELECTED DRAWING: Figure 1

Description

The present invention relates to a mediation system, a mediation method, and a mediation program.

2. Description of the Related Art Conventionally, there have been intermediary systems that mediate electronic commerce between sellers who want to sell specific products (including used products) or services and buyers who want to buy them. The intermediary system covers a variety of things, including movables and real estate. Hereinafter, a used car will be explained as an example of an object to be traded by the intermediary system, but the object to be traded is not limited to used cars.

Generally, there are various reasons for changing a car, such as ``the current car is getting old'' or ``the family structure has changed,'' but everyone wants to buy a car in good condition at a low price. At such times, the desire to ``buy a used car at a reasonable price'' arises among those who wish to purchase a car. On the other hand, if you do not have the prerequisite knowledge about what price is appropriate, you may be confused at the stage of ``choosing a dealer'', which is the pre-choice stage of choosing a used car.

Broadly speaking, car stores include ``dealers'' and ``stores specializing in used car sales.'' On the other hand, cars can be broadly divided into ``new cars'' and ``used cars.'' A new car is an unregistered car that has just been delivered from the factory, and the buyer becomes the first owner. A used car always refers to a car that has been previously owned by someone. There are also cars that are not actually used, but have a history of administrative registration, and are called ``new and used cars'' or ``registered and unused cars.'' However, broadly speaking, "new and used cars" and "registered and unused cars" also belong to the category of used cars.

In general, used car sales specialty stores either purchase cars from buyers or auction off cars from auto auctions, and then perform the necessary repairs. The same applies hereafter), and display the store price at the store and display it. Used cars tend to have similar price ranges if they are similar in attributes such as model, year, mileage, grade, equipment, and color.

In addition to this, there is also a method of buying and selling used cars through direct transactions between individuals without using a used car dealership as an intermediary. This method does not go through a used car specialty dealer, so it can reduce the dealer's margin, allowing the seller to sell the used car at a high price and the buyer to buy the used car at a low price. There is a problem in that reliability can only be guaranteed to a certain extent in terms of price appropriateness, quality assurance, etc.

In Patent Document 1, a used car sales server 20 accesses an auction server 30 equipped with a market price information database based on a request from a user terminal 10, acquires market price information from this market price information database, and transmits the market price information to the user terminal. This is a used car sales system that transmits desired car information to the user terminal, receives bidding information from the user terminal and sends it to the auction server, receives auction result information from the auction server, and sends it to the user terminal. A user terminal that outputs the estimate sent to the car sales server and received from the used car sales server, sets an expected vehicle contract price for the received desired car information, and generates an estimate that includes this vehicle contract price. The technical concept of a used car sales system that includes a used car sales server that sends data to user terminals is disclosed.

Japanese Patent Application Publication No. 2006-268635

When purchasing used vehicles, especially in direct transactions between individuals (so-called "CtoC services") that do not go through used car dealers, the inability to determine the appropriate value of the vehicle becomes a source of uncertainty in the transaction. This is hindering the promotion of sales. Some existing CtoC services calculate a recommended range for vehicle transaction prices; however, in existing CtoC services, the recommended range presented is simply the search price of similar past cases (in other words, the ``vehicle's'' market). There were problems such as prices that could not be calculated properly (prices that could not be calculated properly), and prices that were simply predicted prices based on linear regression. In other words, in this case, there is no certainty or probability that prices related to past similar cases or predicted prices based on linear regression can be said to be appropriate prices in second-hand goods transactions between individuals. The invention of Patent Document 1 also has such a problem.

The vehicle value of a used car traded between traders through an auction is determined by an appraisal association based mainly on the vehicle specifications and condition (model, mileage, model year, repair history, interior/exterior condition, color, failure status, etc.) It is determined by reflecting appraisal standards, demand for each car model, and market conditions for used car retail prices and purchase prices at the time.

In actual pricing operations at used car dealerships, a linear model and certain rules are created based on historical data such as mileage, model year, equipment, etc., and oversubtraction is performed to automatically assess the price of a used car. It is not uncommon for such systems to exist. The Japan Automobile Appraisal Association (General Incorporated Foundation) also recommends using certain rules for appraisals, and currently grants appraiser qualifications based on the ability to make appraisals using these rules. Calculation logic that uses such fixed rules does not reflect qualitative factors such as popularity or model changes, leading to a deviation from actual market conditions.

Since individuals are not allowed to participate in the above-mentioned auctions between traders, they cannot refer to the buying and selling prices of transactions between traders. Therefore, when pricing in private sales (Yahoo Auctions (registered trademark), Mercari (registered trademark), etc.), (1) a certain amount is deducted from the selling price of a used car dealer (Car Sensor, goo) searched on the Internet. (2) An amount that is the purchase price presented by the purchasing store plus a certain amount; (3) An amount that is equivalent to or a certain amount added to the selling price of the used car dealer (desired price);
In many cases, one of the following prices is determined. Currently, the ratio is approximately (1):(2):(3)=3:1:6. The exhibition price is (2)<(1)<(3), and the price in (3) is higher. As a result, we have reached the current situation where some of (2) and (1) are sold, but most of (3) is not. As a result, used cars listed in (3) continue to remain in the private sales market, and individuals who see them try to sell them again at the prices listed in (2) and (3), creating a vicious cycle. In the end, it is not possible to make a transaction at a price that both sellers and buyers are satisfied with.

The present invention is intended to solve the various problems described above, and is aimed at providing a price that both sellers and buyers are satisfied with in consumer-to-consumer (CtoC) transactions of used products (e.g., vehicles). (hereinafter also referred to as "value").

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In this example, descriptions of already known techniques will be omitted. There are various intermediary systems such as movable property and real estate. This example will be explained using used car sales as an example. The present invention is essentially a technical idea related to a platform for trading (including buying and selling; hereinafter the same) of used objects (goods, services) between individuals, and such used objects are limited to used cars. Of course, it is nothing. In the following explanations in this paper, ``a price that makes sense'' is defined as ``an equilibrium price where demand and supply match in transactions between individuals.''

FIG. 1 is a schematic configuration diagram of a mediation system 1 according to an embodiment of the present invention. As shown in FIG. 1, an intermediary system 1 includes a terminal for a used car sales applicant (for example, an information processing terminal related to a seller; the same applies hereinafter) 2 and a terminal for a used car purchase applicant (for example, an information processing terminal related to a seller) 2. An information processing terminal (hereinafter the same) 3 and a used car fair sales price providing server (an information processing server related to an intermediary system; the same hereinafter) 7 communicate with each other via a network (e.g., the Internet; the same hereinafter) 6. Connected and configured.

The used car sales applicant terminal 2 is owned by a person who wishes to sell used cars. A dedicated application for the intermediary system 1 according to an embodiment of the present invention has been downloaded to the used car sales applicant terminal 2. A used car purchase applicant terminal (an information processing terminal related to purchase applicants (including those who conclude a contract)) 3 is owned by a person who wishes to purchase (contract) a used car. A dedicated application for the intermediary system 1 has been downloaded to the used car purchase applicant's terminal 3. Note that although the used car sales applicant terminal 2 and the car purchase applicant terminal 3 are described here as smartphones, for example, they may be terminals having other computer functions.

The used car fair sales price providing server 7 has the function of calculating the value as an equilibrium price where demand and supply match in transactions between individuals for used cars. It has functions to support buying and selling.

The used car fair sales price providing server (for example, an information processing server related to an intermediary system) 7 is realized, for example, as a computer (including a so-called PC) in terms of hardware, and includes a CPU (not shown). The computer is configured to include at least a processing unit), a RAM (Random Access Memory), a ROM (Read Only Memory), a mouse, a keyboard, a display screen, and an interface.

In terms of software, the used car appropriate sales price providing server 7 includes a page providing unit 8, an appropriate price determining unit 9, and a used car sales applicant information storage unit 11 that stores information related to used car sales applicants. A used car purchase applicant information storage unit 12 that stores information related to used car purchase applicants, a value storage unit 13 that stores values, purchase prices of purchasing companies, auction prices between companies, completed listing prices, and properties. a learning model information storage unit 14 that stores learning model information generated from at least one of price data such as market prices such as in-store prices of dealers, and specifications and evaluations that store used car specifications and evaluation information. It includes an information storage section 15 and a control section (not shown) that controls the exchange of various information (including information regarding prices). As a whole system, the above-mentioned functions can be realized by the above-mentioned software appropriately operating the above-mentioned hardware resources (the same applies hereinafter).

"Purchase price" is the purchase price of the purchasing agent, and whether it is a price obtained by linking with the purchasing agent's price calculation system, a price obtained by using the same price calculation system, or a price obtained from the database. The price may be calculated from representative values such as the average value, mode value, median value, etc. obtained by searching, or it may be any price. Alternatively, the price may be obtained by estimating a representative value using machine learning, or estimating a market price or value.

The "exhibition price" is a price displayed on the terminal 2 of the used car sales applicant and indicates how much the used car sales applicant wants to sell the used car for by referring to the purchase price and the market price.

"Market price" is the price obtained by extracting data similar to vehicle specifications from the same model and grade listed at a used car dealer, or by searching a database, and calculating a representative value from the average value. be. In addition to the average value, the representative value may be a statistical representative value such as a mode value or a median value. Alternatively, the representative value may be estimated by machine learning.

"Value" refers to the equilibrium price at which demand and supply match (in other words, the price at which the balance between demand and supply is appropriate in the market) at which both those who wish to sell used cars and those who wish to purchase used cars Define it as a price that gives you a sense of satisfaction. The system uses machine learning to learn from traded price data of at least one of the following: the purchase price of the purchasing agent, the auction price between agents, the completed listing price, and the market price equivalent to the in-store price of the property seller, and estimates the representative price. This refers to the calculated value. Alternatively, it may be a statistical representative value extracted by database search. In addition, it may be a value obtained by correcting these representative values according to the so-called rules of addition and subtraction as determined by the Appraisal Association.

The above-mentioned calculations in the page providing unit 8, appropriate price determining unit 9, and value storage 13 are performed not in the used car appropriate selling price providing server 7, but in the used car sales applicant terminal 2 or the used car purchase applicant terminal 3, for example. It can also be executed within.

The page providing unit 8 provides used car sales applicant terminals 2 (e.g., information processing terminals related to sellers) and used car purchase applicant terminals (e.g., information processing terminals related to purchasers) 3. Provide screens necessary for support. The appropriate price determination unit 9 has a function of calculating an acceptable price value for a used car, and also has a function of supporting sales of used cars and used car buyers in buying and selling.

FIG. 2 is a sequence diagram for explaining the operation of the mediation system 1 according to this embodiment. Although the figure will be explained by showing an example of the operation of the intermediary system 1 according to the present embodiment, the order of each step is not limited to this. The number of purchasers is not limited to two people, one for each item. First, in the used car appropriate sales price providing server 7, a control unit (not shown) determines the market price corresponding to the purchase price of the purchasing agent, the auction price between agents, the concluded listing price, and the in-store price of the property seller. , and stores it in the learning model information storage unit 14 (step S10).

In the used car appropriate sales price providing server 7, a control unit (not shown) transmits information for becoming a member to the used car sales applicant terminal 2. Correspondingly, for example, a used car sales applicant may register membership information such as a sales applicant ID and a sales applicant password in the used car appropriate sales price providing server 7, and download a dedicated application. Then, a dedicated application is downloaded to the used car appropriate selling price providing server 7, and member information such as the sales applicant ID and the selling applicant password is stored as information in a RAM (not shown) of the used car appropriate selling price providing server 7. (Step S11, Step S12). On the other hand, in the used car appropriate sales price providing server 7, a control section (not shown) transmits information for becoming a member to the used car purchase applicant terminal 3. In line with this, for example, a person who wishes to purchase a used car registers member information such as a purchaser ID and a purchaser password in the used car fair sales price providing server 7, and downloads a dedicated application. , a dedicated application is downloaded to the used car appropriate sales price providing server 7, and member information such as the purchase applicant ID and purchase applicant password is stored as information in a RAM (not shown) of the used car appropriate sales price providing server 7 ( Step S13, Step S14).

Next, in the used car appropriate sales price providing server 7, a control section (not shown) requests the used car sales applicant terminal 2 to submit sales car information (including specifications and evaluation information). Along with this, sales car information (including specifications and evaluation information) is transmitted from the control unit (not shown) of the used car sales applicant terminal 2 to the used car appropriate sales price providing server 7, and the used car appropriate sales price is The control section (not shown) of the providing server 7 stores this sales vehicle information (including specifications and evaluation information) in the specifications and evaluation information storage section 15 (steps S15 and S16).

Next, the appropriate price determination unit 9 performs appropriate price determination processing based on the sales vehicle information (including specifications and evaluation information). Thereby, the value is calculated (step S16). Note that the value calculated in this way is stored in the value storage section 13 by the appropriate price determination section 9.

Next, in the used car appropriate sales price providing server 7, the control unit (not shown) notifies the used car sales applicant terminal 2 of the value, purchase price, and market price (step S17). Note that the purchase price and market price are also calculated by the appropriate price determination unit 9 from the sales vehicle information stored in the specification and evaluation information storage unit 15.

Next, the exhibition price of the used car is determined based on the value, market price, and purchase price displayed on the used car sales applicant's terminal 2. Specifically, for example, a used car sales applicant looks at the value, market price, and purchase price displayed on the used car sales applicant terminal 2, and inputs a listing price into the used car sales applicant terminal 2. As a result, after the used car sales applicant terminal 2 acquires the information related to the listing price, the control unit (not shown) of the used car sales applicant terminal 2 transmits the information related to the listing price to the used car appropriate sales price providing server. 7 (step S18).

Next, the value, exhibition price, and market price are transmitted to the used car purchase applicant terminal 3 by the control unit (not shown) of the used car appropriate sales price providing server 7. (Step S19, Step S20).

Next, in the used car purchase applicant terminal 3, the control unit (not shown) transmits information such as "like", "expensive", "cheap", etc. to the used car appropriate sales price providing server 7. (Step S21, Step S22).

Next, in the used car appropriate sales price providing server 7, a control unit (not shown) determines whether the sale has been completed (step S23). If it is determined that the sale has been completed, the control unit (not shown) registers the actual results and the contract price in, for example, a RAM (not shown) or the like (step S24). Then, in the used car appropriate sales price providing server 7, the control unit (not shown) transmits the sales completion information to the used car sales applicant terminal 2 and the used car purchase applicant terminal 3 (step S25, step S26). ). Then, the control unit (not shown) updates the learning model using the established contract price as training data and the specifications and evaluation information used this time as input data (step S27). This updates the learning model to a more appropriate one.

If the sale is not completed (step S28), the process proceeds to the flow of FIG. 3.

FIG. 3 is a flowchart of the case where negotiation for a reduction in the listing price is performed in the intermediary system 1 according to the present embodiment. Although the figure will be described by showing an example of the operation of negotiating a discount on the listing price in the intermediary system 1 according to the present embodiment, the order of each flow is not limited to this. First, a person desiring to sell a used car and a person desiring to purchase a used car decide whether to negotiate the price for buying and selling the used car. If it is determined not to negotiate, the process ends.

Next, in the used car appropriate sales price providing server 7, a control unit (not shown) sends change request information related to a request to change the listing price to the used car sales applicant terminal 2 (information processing terminal related to the seller). is sent.

When responding to a change in the listing price, the listing price related to the change request is transmitted to the used car appropriate selling price providing server 7 by the control unit (not shown) in the used car sales applicant terminal 2.

If the listing price change is not supported, information indicating that the change is not supported is transmitted by the control unit (not shown) in the used car sales applicant terminal 2 to the used car appropriate sales price providing server 7, and the used car appropriate sales price provision server 7 is sent. Via the server 7, information is sent to the used car purchase applicant's terminal 3 that it is not possible to change the listing price.

Alternatively, regarding the operation in response to the above change in the listing price and the operation in the case not to respond to the change in the listing price, the used car sales applicant terminal 2 (control unit not shown) and the used car purchase applicant The user terminal 3 (control unit, not shown) may directly negotiate a change request, and the resulting information may be transmitted to the used car appropriate sales price providing server 7.

Next, the person wishing to sell a used car decides the listing price again. Specifically, when the used car sales applicant inputs the relisting price on the used car sales applicant terminal 2, the used car sales applicant terminal 2 (control unit, not shown) changes the relisting price to ( (in a RAM (not shown), etc.), and necessary information is presented in the same manner as in the above flow (step S29). A control unit (not shown) determines whether a contract has been concluded at the newly presented re-listing price (step S30). If it is determined that the contract has been concluded, the series of operations/functions described above are completed. If the contract is not concluded, the control unit (not shown) returns the process (step S28).

Next, when it is determined (by a control unit (not shown) that a contract has been concluded), the control unit (not shown) uses training data for learning a learning model (AI model) that estimates value (or estimates by database search). Record the closing price (as data for). The learning model (AI model) is updated at any timing, such as regularly or immediately.

Next, the value calculation operation of the intermediary system 1 according to the present embodiment will be explained.

The appropriate price determination unit 9 uses at least one of the price data stored in the learning model information storage unit 14 as teacher data, that is, an objective variable, and uses the used car specifications and evaluation information stored in the specification and evaluation information storage unit 15. Machine learning is performed using the learning model stored in the learning model information storage unit 14 as input data. Alternatively, the value may be the market price corresponding to the purchase price of the purchasing agent, the auction price between agents, the completed listing price, or the in-store price of the property seller based on the price data stored in the learning model information storage unit 14. It may be calculated by data matching between at least one of the specifications and evaluation information.

After that, the control unit (not shown) adds the listing price (selling price) of the used car when a deal is concluded as training data, and performs machine learning using the used car's specifications and evaluation information as input data. , making the learning model more reliable.

The value is stored in the value storage unit 13 of the used car appropriate sales price providing server 7, for example, by a control unit (not shown).

The value may also be calculated using a function F(x). Here, the explanatory variable vector is the vehicle manufacturer, model, grade, model year, mileage, repair history, smoking status, pet ride status, interior and exterior evaluation (assessment association standards, personal evaluation, rule-based or Machine learning evaluation, etc.), presence of equipment (navigation, air conditioner, sunroof, navigation, leather seats, heat seat, safe driving support, etc.), vehicle color, vehicle inspection period remaining, listing period (when it was put on sale), spare keys and maintenance. It is a function where x is the presence or absence of equipment such as record books, the number of accesses to the exhibited vehicle, the number of likes, the number of inquiries, the number of comments, etc.

The AI (Artificial Intelligence) learning of this embodiment includes deep learning, a decision tree algorithm such as random forest, a learning algorithm using a kernel function such as SVM, a nonlinear regression function (or machine learning model) such as polygonal regression, It may be based on any linear regression function such as ridge regression or lasso regression.

In order to perform statistical learning, we pinpoint statistically appropriate values from direct transaction results using a dedicated application (or externally) rather than just database matching. At this time, accidental variations in actual transaction prices are recognized and learned as variations. Due to the logic of the learning model (AI model), it is possible to respond to intermittent price changes such as model changes. It is possible to respond to market fluctuations while using past data.

FIG. 4 is a diagram schematically showing a screen on which specifications of a used car are input in the system according to the present embodiment. As shown in the figure, for example, a used car sales applicant inputs information regarding the specs of a used car on the used car sales applicant terminal 2. The specs include information regarding the condition, basic specs, and equipment. "Condition" here includes manufacturer, vehicle type, grade, model, year, mileage, vehicle inspection expiration date, repair history, color, exterior features, interior features, overall evaluation, purchase date, monthly mileage, and smoking.・Contains at least one of the following information regarding smoking bans, pets, maintenance records, etc.

FIG. 5 is a diagram showing an example of a screen used to input the condition of a used car according to the present embodiment. Inspection items include, for example, the following: For example, a used car sales applicant inputs the inspection results of 69 items such as exterior, interior, operation, etc. from the used car sales applicant terminal 2. However, the test results are not limited to 69 items.

FIG. 6 is a diagram showing an outline/arrangement of a screen on which a photo screen of a used car according to the present embodiment is presented. At the used car sales applicant terminal 2, a control unit (not shown) captures images of the front, top, left and right sides, rear side, etc. of the used car and transmits them to the used car appropriate sales price providing server 7.

FIG. 7 is a diagram showing an example of a value display screen according to the present embodiment. Value is a price that satisfies both the seller (who wants to sell a used car) and the person who wants to buy (including those who have completed the contract) (who wants to buy a used car). The information terminal (used car sales applicant terminal 2) and the information terminal (used car purchase applicant terminal 3) related to purchase applicants (including those who have completed the contract) are equipped with the following information (for example, as shown in the lower part of the figure). ) to be displayed. Further, the market price and the purchase price are displayed on the used car sales applicant terminal 2. The listing price is determined by operating the used car sales applicant terminal 2 (for example, the listing price information is edited by an editing function not shown). In this case, the purchase price may be displayed on the used car purchase applicant's terminal 3.

In detail, for example, the purchase price, value, and representative market price are displayed on the used car sales applicant's terminal 2 (screen display section), and the seller decides the listing price based on this. In this case, the listing price can be determined by looking at not only the purchase price and the representative market price, but also the value. This system guarantees support for determining a listing price that is acceptable for transactions. From the opposite perspective, the purchaser can refer to the (purchase price), value, market price, and listing price displayed on the used car purchase applicant terminal 3 and proceed with the purchase with a sense of satisfaction. It means possible. Representative values (pinpoints) of purchase price, value, market price, and listing price may be presented. The representative value may be expressed as a point, or it may be a standard deviation or confidence interval calculated from the price distribution on which the representative value is calculated, or a statistic that represents the tendency of the distribution, such as the minimum and maximum value of the distribution. You may also write range using , or you may write range and point together. The screen showing the representative value may be expressed by superimposing the distribution itself, which is the basis for calculating the representative value, on the histogram. The representation of the above distribution may be displayed on a separate screen. The above distribution may be expressed using a scatter diagram or a heat map that includes specific vehicle specifications as an axis. The screen showing representative values may not only be expressed on one axis based on price, but may also be expressed multidimensionally, including vehicle specifications, by adding specific vehicle specifications to another axis. The screen showing the representative values does not have to be expressed using axes, but may be expressed simply as a table or as a list of items.

FIG. 8 is a diagram showing an example of a screen on which used car selection can be performed according to the present embodiment. Pictures of used cars A to J are displayed on the screen related to the figure. For example, a prospective purchaser can obtain detailed information about the used car by tapping an image of the used car of their choice on the screen showing the displayed photo. This operation can be performed by the used car purchase applicant via the used car purchase applicant terminal 3.

FIG. 9 is a diagram showing an example of a screen for viewing comments about used cars according to the present embodiment. Here, an example is shown in which comments from purchasers and viewers are posted. Those who wish to purchase a used car can view the comments on the display screen of the used car purchase applicant's terminal 3 and refer to them when making a purchase.

FIG. 10 is a diagram showing an example of a screen for deciding on a purchase in this embodiment. The information terminal (used car purchase applicant terminal 3) related to the purchase applicant (including the person who has completed the contract), where "value" is the price that gives a sense of satisfaction to the purchase applicant (including the person who has completed the contract) (used car purchase applicant). will be displayed. Furthermore, the market price equivalent to the selling price at the store and the listing price determined by the person wishing to sell the used car are displayed. Those who wish to purchase (including those who have completed the contract) can decide whether or not to purchase by operating the terminal 3 for those who wish to purchase a used car.

The value is not limited to being calculated by the appropriate price determination unit 9 of the used car appropriate sales price providing server 7, but may be calculated by a dedicated application installed on the sales applicant terminal 2 and/or in collaboration with a dedicated application. , may be calculated.

Since the degree of certainty of value changes depending on the variation in data and/or the amount of data, the degree of confidence in value may be calculated by the appropriate price determination unit 9. Here, the confidence level is a measure of the certainty of a value.

Each aspect of the present invention can be implemented by the following embodiments in addition to the embodiments described above. That is, for example, it may be established as a platform for intermediary transactions between individuals such as used cars, ie, CtoB, BtoB, BtoC, etc. In addition, the value includes at least one of the following: the purchase price of the purchasing agent, the auction price between agents, the completed listing price, the market price equivalent to the in-store price of the property seller, and information related to the seller. It may be calculated by data matching with seller input information consisting of property specifications and evaluation information input from a processing terminal.

Value includes vehicle manufacturer, model, grade, model year, mileage, repair history, smoking, presence of pets, interior/exterior evaluation, presence of equipment, vehicle color, vehicle inspection period remaining, presence of spare keys, maintenance records, etc. , past owner history, exhibition period, number of accesses to the exhibition vehicle, number of likes, number of inquiries, and number of comments.

Among the above explanatory variables, if one variable is in a state of decreasing value, it is difficult for other variables to increase the value, for example, ``Even if the mileage is short, if the model is older, it is difficult for the value to increase.'' This calculation (calculated assuming that there is an interaction between variables) may be performed.

The value may be calculated differently for each manufacturer's vehicle model, each grade, and/or each vehicle condition.

It may also support at least one of insurance procedures, land transportation arrangement procedures, name change procedures, and payment procedures incidental to the transaction, as well as maintenance guarantees.

Additionally, it is possible to pick up and receive a car through a land transportation company without meeting in person. Land transportation can be arranged using a smartphone. By having the office check the name change documents in advance, which are prone to mistakes, it will help prevent problems with changing the name after receiving the car. The secretariat will hold the money until the vehicle and documents are received, making the exchange of large sums of money safe.

FIG. 11 is a diagram showing an example of an explanatory diagram illustrating a screen for recommending buying and selling prices according to the present embodiment. Instead of displaying value, another method of displaying "recommended prices" is to display recommended sales prices, used car store purchase prices, and used car store sales prices in order to give a sense of understanding to both sellers and potential buyers. The price, the seller's merit price and the purchaser's merit price when selling at the recommended price may be displayed on the information processing terminal of the seller and the information processing terminal of the purchaser.

FIG. 12 is a conceptual diagram for explaining price fluctuation analysis using each element of an explanatory variable vector according to this embodiment. For example, compared to the standard price of a used car you want to sell, the price varies depending on the year of the used car. Prices vary depending on the mileage of the used car. Additionally, the price fluctuates depending on the vehicle inspection deadline for used cars. Prices vary depending on the exterior of the used car. Prices vary depending on the interior of the used car. Prices vary depending on the car seat of a used car. Prices vary depending on whether a sunroof is included or not. Taking these into consideration, the value is displayed on the used car sales applicant terminal 2 of the person wishing to purchase a used car and/or the used car purchase applicant terminal 3 of the person wishing to purchase a used car. The price fluctuation analysis chart as shown in FIG. 12 may be displayed on the used car sales applicant terminal 2 of the used car purchase applicant and/or the used car purchase applicant terminal 3 of the used car purchase applicant. It doesn't have to be done. Moreover, the method of displaying price fluctuations for each variable does not have to be the step graph shown in the figure, but may be a bar graph, a pie chart, or a general method of expressing a breakdown such as a simple enumeration of numerical values or a table.

Price fluctuation analysis can be obtained by calculating the perturbation of each explanatory variable using a trained model, for example, by calculating the contribution of each variable to the price difference of a specific used vehicle with respect to the market average. . This makes it possible to explain the breakdown of value, create a sense of "conviction" about value, and calculate the equilibrium price where demand and supply match.

To calculate this price fluctuation analysis, you can simply look at the amount of change when only a specific variable is changed with respect to the market average vehicle specifications, or you can use local partial differentiation, the SHAP method, Lime, etc. Variable contribution interpretation methods for nonlinear models that have been seen in recent years may also be used.

Although this embodiment has been described above, this embodiment is not limited to these, and various changes can be made within the scope of the gist of this embodiment. Furthermore, the present invention is not limited to buying and selling transactions between individuals, but may be used as an intermediary system for buying and selling transactions between businesses.

Since the intermediary system according to each aspect of the present invention can be used for commercial transactions, it has economic value and is an invention that can be used industrially.
