Method and device for constructing user portrait based on big data, and computer equipment

Abstract

The invention discloses a method and a device for constructing user portrait based on big data, computer equipment and a computer storage medium. The method comprises the following steps of obtainingthe behavior information of a user operating application programs, and information of a list of installed application programs at a user terminal; utilizing a first deep learning algorithm to learn the behavior information, so as to obtain user behavior feature vectors; utilizing a second deep learning algorithm to learn the information of the list of installed application programs at the user terminal, so as to obtain application program feature vectors of the installed application programs at the user terminal; according to the user behavior feature vectors and the application program feature vectors, constructing the user portrait. By adopting the technical scheme, the method has the advantage that when the user portrait is constructed on the basis of big data, the features of the usercan be fully reflected, so as to provide finer services for the user according to the user portrait, and overcome the defect of low quality of the user portrait due to reliance on one-element data ofthe user, such as age and gender, in the user portrait construction process of the prior art.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a user portrait construction method, device, computing device and computer storage medium based on big data. Background technique [0002] With the continuous development of network and information technology, various platform applications are born. In order to improve the various functions of the platform, to facilitate the platform to provide users with better services, and to protect the interests of the platform, it is necessary to understand and analyze various aspects of users. information. At present, user information is often learned by constructing user portraits. [0003] Existing user portrait construction methods mainly construct user portraits based on the user’s unary data, such as gender, age, occupation, constellation, height, weight, shopping type, brand preference and / or income, etc., and do not make full use of the factors The big data generat...

[0003] Existing user portrait construction methods mainly construct user portraits based on the user’s unary data, such as gender, age, occupation, constellation, height, weight, shopping type, brand preference and / or income, etc., and do not make full use of the factors The big data generated by the Internet, although the user portrait constructed by using the unary data can guide the platform, but it cannot fully reflect the characteristics of the user, so that the platform cannot provide users with refined services, and it is impossible for the user to be fraudulent, etc. Protect the interests of the platform when acting
