Problems solved by technology

[0002] At present, major vehicle trading websites focus on buying and selling new cars. The second-hand car market is a scene worth exploring. However, according to the existing used car recommendation algorithm, a user may only search for a few models. Using such a small amount of data to speculate A large amount of unknown information will cause errors in the algorithm, lack of accuracy and interpretability,
[0003] For the lack of accuracy and interpretability of the above-mentioned used car recommendation algorithm, no effective solution has been proposed so far

Embodiment 1

[0028] According to an embodiment of the present invention, an embodiment of a method for recommending a vehicle based on user information is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings may be implemented in a computer system such as a set of computer-executable instructions. and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that herein.

[0029] figure 1 is a flow chart of a method for recommending vehicles based on user information according to an embodiment of the present invention, such as figure 1 As shown, the method may include the following steps:

[0030]Step S102 , collecting user information of the logged-in user currently logged into the application platform, wherein the application platform is a vehicle trading platform, and the user information includes: basic user information and vehicle information of the vehicle re...

Embodiment 2

[0060] The technical solutions of the embodiments of the present invention are illustrated below with reference to the preferred embodiments.

[0061]Most of the traditional recommendation algorithms belong to the coordinated filtering recommendation. This algorithm is one of the earliest recommendation algorithms. Generally, the nearest neighbor technology is used. First, the distance between users is calculated by using the user's historical preferences, and then the nearest neighbor users are found. The user's evaluation of the product and the weighted value of the preference determine the user's preference for the product. The background system recommends the user according to the preference degree. The premise of recommending the user is to find other users with similar interests to the user. This recommendation can sort out simple relationships, so that simple unstructured objects can be easily handled. However, when the content is complex, the number of users is increasi...

Embodiment 3

[0099] According to an embodiment of the present invention, an apparatus for recommending a vehicle based on user information is also provided. It should be noted that the apparatus for recommending vehicles based on user information can be used to execute the method for recommending vehicles based on user information in Embodiment 1.

[0100] Figure 9 It is a schematic diagram of a device for recommending vehicles based on user information according to an embodiment of the present invention. like Figure 9 As shown, the device 900 for detecting the boundary on the driving area of ​​the vehicle may include: a collection module 901, a determination module 902, a processing module 903, and a transmission module 904.

[0101]The collection module 901 is used to collect the user information of the logged-in user currently logged into the application platform, wherein the application platform is a vehicle trading platform, and the user information includes: basic user informatio...

Abstract

The invention discloses a vehicle recommendation method and device based on user information. The method comprises the steps that user information of a login user currently logging in an application platform is collected, and the user information comprises user basic information and vehicle information of a vehicle needed by the user; at least one interaction user associated with the login user is determined, the interaction user is a registered user having a network interaction behavior with the login user in the application platform, and the network interaction behavior between the login user and any one or more interaction users forms social circle information of the application platform; inputting user information of the login user and / or interaction user information of at least one interaction user associated with the login into the constructed knowledge graph model, and generating recommendation information to be recommended to the login user; and sending the recommendation information to equipment held by the login user. The technical problem that the second-hand car recommendation algorithm lacks accuracy and interpretability is solved.

Description

technical field [0001] The present invention relates to the field of vehicles, and in particular, to a method and device for recommending vehicles based on user information. Background technique [0002] At present, major vehicle trading websites focus on the sale of new cars, and the used car market is a scene worth exploring. However, according to the existing used car recommendation algorithm, a user may search for only a few models, and use such a small amount of data to speculate A large amount of unknown information will cause errors in the algorithm, lack of accuracy and interpretability, [0003] Aiming at the lack of accuracy and interpretability of the above-mentioned used car recommendation algorithm, no effective solution has been proposed yet. SUMMARY OF THE INVENTION [0004] Embodiments of the present invention provide a method and apparatus for recommending vehicles based on user information, so as to at least solve the technical problem that the used car ...
