Problems solved by technology

[0004] It can be seen that the construction method of the used car pricing model shown in the prior art only considers the influence of numerical information on the price of used cars during the construction process, and there is a large gap between the constructed used car pricing model and the actual transaction situation of used cars. Differences, using the used car pricing model shown in the prior art to evaluate the price of used cars, its accuracy is difficult to guarantee

Embodiment 1

[0061] In the construction method of the used car pricing model shown in the prior art, in the construction process, only the influence of numerical information on the used car price is considered, and the constructed used car pricing model is quite different from the actual transaction situation of the used car. , using the used car pricing model shown in the prior art to evaluate the price of a used car, the accuracy of which is difficult to guarantee.

[0062] In order to solve the technical problems existing in the prior art, the first aspect of the embodiments of the present application shows a method for constructing a pricing model for used cars. For details, please refer to figure 1 , the method includes:

[0063] S101 acquires vehicle data of a modeled vehicle, the vehicle data includes vehicle condition information of the modeled vehicle, and a transaction price of the modeled vehicle, the vehicle condition information includes: numerical information and text informa...

Embodiment 2

[0077] Usually in the process of building a used car pricing model, in the process of converting text information into a computer-recognizable language, the similarity between unused texts cannot be accurately measured, such as engine oil leakage and serious engine oil leakage, which may As the same influencing factor; however, in actual situations, engine oil leakage and serious engine oil leakage obviously have different degrees of impact on the price of used cars. Influencing factors, the accuracy of the constructed used car pricing model is difficult to guarantee;

[0078] In order to solve the above problem, the embodiment of the present application shows a method for generating a text vector. For details, please refer to figure 2 ,as well as, image 3 ;

[0079] Embodiment 2 The technical solution shown in Embodiment 1 has similar steps to the technical solution shown in Embodiment 1, and the only difference is that in the technical solution shown in Embodiment 1, the...

Embodiment 3

[0104] In order to reduce the data processing amount of the application platform, the embodiment of the present application shows a method for filtering vocabulary. For details, please refer to Figure 4 ;

[0105] Embodiment 3 The technical solution shown in Embodiment 2 has similar steps to the technical solution shown in Embodiment 2, and the only difference is that in the technical solution shown in the embodiment, the word segmentation preprocessing is performed on the text information to obtain The steps of the thesaurus include:

[0106] S10211 performs word segmentation on the text information according to a preset rule to obtain a first thesaurus, where the first thesaurus includes words obtained by performing Chinese word segmentation on the text information;

[0107] Specifically, the subject-predicate participle method can be used:

[0108] For example: replacement of front wheel; the result after word segmentation by subject-predicate participle is: front wheel,...

Abstract

The embodiment of the present application shows a method for constructing a pricing model for a used car, a pricing method and an apparatus. The method shown in the embodiment of the present application converts text information into a computer-recognizable text vector in advance, and then combines the text vector and numerical information. , as the price influencing factor, and then, according to the price influencing factor and the transaction price, a used car pricing model is constructed. It can be seen that the technical solutions shown in the embodiments of the present application, in the process of constructing the pricing model of used cars, at the same time, considering text information and numerical information, the entire modeling environment is closer to the actual trading environment of second-hand cars, so as to ensure that this application is used only The used car pricing model constructed in the embodiment can accurately evaluate the price of the used car.

Description

technical field [0001] The invention relates to the technical field of computers, and in particular to a method for constructing a pricing model for a used car, a pricing method and a device. Background technique [0002] With the improvement of living standards, cars have become a common means of transportation in ordinary families. More and more consumers choose to buy a car to bring convenience to their daily life. In recent years, with the development of economy and society and the improvement of living standards of urban residents, vehicles have become a basic requirement of private individuals. In recent years, with the rapid development of China's economy and the rapid growth of vehicle ownership, the trading of second-hand cars has become more and more prosperous, and second-hand cars are usually carried out on vehicle trading platforms. [0003] The vehicle trading platform first acquires second-hand cars in stores or individuals, usually obtains the vehicle data ...
