Second-hand car value evaluation method

Abstract

The invention relates to vehicle value evaluation, in particular to a second-hand vehicle value evaluation method, which comprises the following steps of: acquiring and updating internet public second-hand vehicle data in real time, and processing the second-hand vehicle data; modeling is carried out on the second-hand car data after data processing; matching is carried out in the model according to actual input information, a candidate set is obtained, matching degree scoring is carried out on the candidate set, and the vehicle with the highest score is selected as an evaluation object; data acquisition and data preprocessing are carried out, and a vehicle value evaluation network topology structure is determined; an improved ant colony algorithm is adopted to optimize the weight initialization process of the vehicle value evaluation network, and the vehicle value evaluation network is utilized to evaluate the value of the evaluation object; according to the technical scheme provided by the invention, the defects that information symmetry of second-hand car buying and selling cannot be realized and accurate value evaluation cannot be carried out on the second-hand car in the prior art can be effectively overcome.

Description

technical field [0001] The invention relates to vehicle value evaluation, in particular to a used car value evaluation method. Background technique [0002] With the continuous development of second-hand car transactions in e-commerce, the appraisal and evaluation of second-hand cars, which play an important role in the process of second-hand car transactions, needs to be constantly regulated and improved to meet market needs. At present, the second-hand car market is still a market with asymmetric information, and it is difficult for consumers to obtain real transaction information of second-hand cars. As a result, it is difficult for the second-hand car market to gain the trust of consumers, and many potential second-hand car demands are difficult to transform into a real market. trade. [0003] In the second-hand car market, second-hand cars are non-standard products, and there is no unified pricing method. At present, the pricing services in the market are uneven, the ...
