[Embodiment]
A configuration and operation of a used car sales support system according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG.

FIG. 1 is a schematic diagram showing an example of the configuration of a used car sales support system 100 according to this embodiment. The used car sales support system 100 is composed of WEB servers 101 to 103, a network 2, a server device 3, and a user terminal 4. FIG. The WEB servers 101 to 103, the server device 3, and the user terminal 4 are connected via the network 2 and are in a communicable state. The user terminal 4 can access the WEB servers 101 to 103 and the server device 3 . Although FIG. 1 shows three WEB servers, one server device, and one user terminal, the number of servers and terminals is not limited to this.

The network 2 is a communication network capable of high-speed communication, and is, for example, a wired or wireless communication network such as an intranet or LAN (Local Area Network). The server device 3 is, for example, a cloud server and is constructed with a plurality of data servers. The user terminal 4 is a computer having an information processing function, a communication function, and an information input/output function, and is, for example, a desktop computer, a notebook computer, a tablet terminal, a smart phone, or the like.

A user who uses the user terminal 4 is, for example, a consumer who is considering purchasing a used car, or a used car dealer who runs a used car sales business.

FIG. 2 is a block diagram showing a configuration example of the server device 3. As shown in FIG. The server device 3 includes a communication unit 31 that communicates with the outside via the network 2, a control unit 32 that executes various programs, and a storage unit 33 that stores programs 330 executed by the control unit 32. have.

The control unit 32 executes the receiving unit 320 and the program 330 stored in the storage unit 33 to obtain the information acquisition unit 321, the storage unit 322, the estimation unit 323, the statistics unit 324, and the evaluation unit 325. , the transmitting means 326 and the like.

Receiving means 320 receives a request to view used car sales sites A to C. FIG. A viewing request is executed by, for example, a user operation on the user terminal 4 .

The information acquisition means 321 continuously acquires, at predetermined intervals, a property information group consisting of a plurality of used car property information posted on the used car sales sites A to C provided by the WEB servers 101 to 103 . The predetermined interval is not particularly limited, but may be, for example, 24 hours or one week. Since it will be smaller, the most up-to-date information will be obtained. In addition, the information acquisition means 321 acquires used car property information including various information related to used car sales posted on each site by using a scraping technique, for example.

The storage unit 322 stores the property information group acquired by the information acquisition unit 321 as acquisition information 331 in the storage unit 33 . A property information group is collective data consisting of a plurality of used car property information. The storage unit 322 also stores information obtained by the estimation unit 323 and the evaluation unit 325 as estimated information 332 in the storage unit 33 .

The estimating means 323 estimates the contract price of the used car property based on the acquired information 331 consisting of the property information group stored by the storage means 322 .

More specifically, the estimating means 323 selects, in the obtained information 331 stored by the storing means 322, the current property information group 331A (shown in FIG. When there is used car property information that does not exist in the current property information group 331B (shown in FIG. 3 described later) acquired by the information acquisition means 321 of , the used car property information that does not exist in the current property information group 331B Information on the sales price of the corresponding used car property is extracted from the previous property information group 331A, and the extracted information on the sales price is estimated as the contract price of the used car property. Details of the estimation means 323 will be described later.

The statistical means 324 selects used car property information similar to each other based on various information included in the plurality of used car property information from the acquired information 331 stored by the storage means 322, and collects the selected used car property information. Output statistical price information obtained by statistically processing the contract price of the information. The statistical price information is, for example, an average contract price of contract prices for each of a plurality of pieces of contract property information.

The evaluation means 325 compares the statistical price information statistically processed by the statistical means 324 with the contract price estimated by the estimation means 323, and generates evaluation information for the used car property information linked to the contract price. do.

For example, when the contract price of the target used car property information is higher than the average contract price obtained by the statistical means 324, the evaluation means 325 determines that the used car property information is traded at a price higher than the market price. Assuming that a car has been purchased, rank C is given as a low evaluation to the used car property information. On the other hand, if the contract price is lower than the average contract price, it is assumed that the used car was purchased at a lower price than the market price, and rank A is given as a high evaluation to the used car property information linked to the contract price. In other words, the evaluation means 325 gives a high evaluation to a property that has been more advantageous in purchasing or purchasing a used car. In addition, the evaluation means 325 assigns rank B to the used car property information when the contract price and the average contract price are the same. In this way, in the above example, the evaluation information generated by the evaluation means 325 is an evaluation of whether or not a good purchase was made for the used car dealer in the used car sales transaction with respect to the used car property information that has already been contracted. It is also an evaluation index of whether or not a favorable used car transaction was successful for general consumers who wish to purchase.

As a modification, the evaluation means 325 may evaluate the selling price included in the property information posted on the used car sales site. For example, if the selling price of used car property information on sale posted on a used car sales site is higher than the average estimated price, the evaluation means 325 determines that the property is higher than the market price, and assigns the evaluation information a low rank of C. to give In other words, in this example, the evaluation information generated by the evaluation means 325 serves as an evaluation index as to whether or not a good transaction was made for a consumer who wishes to purchase a used car.

The storage unit 33 stores a program 330 executed by the control unit 32 , acquisition information 331 acquired by the information acquisition unit 321 of the control unit 32 , and estimation information 332 estimated by the estimation unit 323 .

The transmitting means 326 transmits the information on the contract price estimated by the estimating means 323 to the user terminal 4 including the used car property information. Further, the transmitting means 326 transmits the used car property information including the statistical price information obtained by the statistical means 324 to the user terminal 4 . Further, the transmitting means 326 transmits the evaluation information by the evaluating means 325 to the user terminal 4 including the used car property information. The transmitting means 326 may transmit estimated information 332 to be described later to the user terminal 4 .

Next, the details of the estimation means 323 of the control section 32 will be described in detail with reference to FIGS. 3 and 4. FIG. FIG. 3 is a schematic diagram showing an example of the acquired information 331. As shown in FIG. FIG. 4 is a schematic diagram showing an example of the estimation information 332. As shown in FIG.

As shown in FIG. 3, the information obtained by the information acquisition means 321 at the time of previous acquisition is stored in the storage unit 33 by the storage means 322 in the previous property information group 331A. The information stored in the storage unit 33 by the 322 is the current property information group 331B. In FIG. 3, the information acquisition means 321 acquires the used car property information at intervals of 24 hours, and three property information items among the property information acquired last time will be described as an example.

The previous property information group 331A includes the acquisition date acquired by the information acquisition means 321, property ID for uniquely identifying the used car property information, vehicle type, model year, and used car property information posted on the used car sales site. It includes the publication start date, sales store, sales price, etc. Various information included in the previous property information group 331A is not limited to this, and may include information necessary for used car sales, such as travel distance and used car specifications.

The estimation means 323 compares the previous property information group 331A and the current property information group 331B, and estimates the contract price based on the difference. That is, the estimation means 323 identifies used car property information that exists in the previous property information group 331A but does not exist in the current property information group 331B, based on the difference between the previous property information group 331A and the current property information group 331B. and extract. In the example shown in FIG. 3, the used car property information with the property ID "002" is extracted as the difference between the previous property information group 331A and the current property information group 331B. Then, the estimating means 323 sets the sales price "3.2 million" included in the used car property information with the property ID "002" in the previous property information group 331A as the contract price of the used car property information with the property ID "002". It is estimated, and the storage means 322 stores this as estimation information 332 (shown in FIG. 4). At this time, the storage means 322 stores the acquisition date of the current property information group 331B as the estimated contract closing date, stores the evaluation information by the evaluating means 325 as the evaluation rank, and stores the status as "closed".

FIG. 5 is a flowchart showing an operation example of the control unit 32 of the server device 3. As shown in FIG.

First, the receiving means 320 of the control unit 32 determines whether or not there is a request to view any one of the used car sales sites A to C by the user's operation on the user terminal 4 (step S30). If there is a viewing request (step S30: Yes), the information acquisition means 321 acquires information posted on the used car sales site (step S31). On the other hand, if there is no browsing request (step S30: No), the process of step S30 is executed again.

Next, the storage unit 322 stores the acquired information in the storage unit as the acquired information 331 (step S32), and the estimation unit 323 stores the previous property information group 331A (shown in FIG. 3) and the current property information group 331B (shown in FIG. 3). ) are compared (step S33).

Then, it is determined whether or not there is information in the current property information group 331B that does not contain used car property information corresponding to the used car property information included in the previous property information group 331A (step S34). In other words, the estimating means 323 detects property information that exists in the previous property information group 331A but does not exist in the current property information group 331B in the difference data between the previous property information group 331A and the previous property information group 331A. determine whether

If there is used car property information that exists in the previous property information group 331A but does not exist in the current property information group 331B (step S34: Yes), the selling price of the used car property information in the previous property information group 331A is estimated as the contract price of the used vehicle of the used vehicle property information (step S35). On the other hand, if there is no used car property information that exists in the previous property information group 331A but does not exist in the current property information group 331B (step S34: No), the process of step S34 is repeated.

Next, the statistical means 324 extracts used car property information having similar information, and generates an average contract price as statistical processing information based on the estimated price of each of the extracted used car property information (step S36). ). Then, the evaluation means 325 generates evaluation information for the contract price estimated by the estimation means 323 (step S37).

The storage unit 322 stores information such as the estimated price estimated by the estimation unit 323, the average contract price generated by the statistical unit 324, and the evaluation information generated by the evaluation unit 325 as the estimated information 332 in the storage unit 33 (step S38). At this time, the estimated closing date and status may be stored. For the estimated contract closing date, for example, the acquisition date in the used car property information in the previous property information group 331A corresponding to the used car property information that did not exist in the current property information group 331B may be used as the estimated contract closing date.

Finally, the transmission means 326 transmits the estimated information 332 stored in the storage unit 33 to the user terminal 4 (step S39), and the process ends.

(Effect of Embodiment)
According to the above-described embodiment, the used car property information posted on the used car sales site is acquired at predetermined intervals, and the acquired used car property information is compared in chronological order. Since the sales price at the time when the listing on the site is finished is estimated as the contract price of the used car property information whose publication is finished, the contract price of the used car can be estimated by a simple method.

In addition, since statistical price information on the contract price estimated by the estimation means 323 can be obtained by the statistical means 324, it is possible to provide useful information for determining whether to purchase or purchase a used car.

[Other embodiments]
It should be noted that the present invention is not limited to the above-described embodiments, and can be modified as appropriate without departing from the scope of the present invention.

In the above-described embodiment, the transmission means 326 transmits the estimation information 332 only to the user terminal 4. However, the present invention is not limited to this. is also good (see Figure 6). The used car evaluation site is a site provided by the WEB server D. For example, it is possible to refer to general basic information about used cars of a specific year, color, car model, etc., and comments from multiple purchasers. It is a site where you can By providing such a used car evaluation site with the contract price of the estimated information 332 in the present invention, it is possible to present useful information necessary for purchasing a used car, thereby increasing the reliability and convenience of the used car evaluation site. can be improved.

Also, in the above embodiment, the items of the estimated information 332 are not limited, and may include, for example, information on sales speed for each property ID. The information on the sales speed is information obtained by the number of days difference between the publication start date of the acquired information 331 and the estimated contract date of the estimated information 332. The smaller the number of days difference, the faster the sales speed. The evaluation means 325 may evaluate each store based on the information on the sales speed. In this case, the evaluation unit 325 may be configured, for example, to give a higher evaluation to a sales store that holds more properties with a faster sales speed.
