Abstract

The invention discloses a user portrait construction method, system and device and a storage medium. The method comprises the steps of S1, obtaining user data; s2, processing the user data by adopting a word embedding model to obtain an embedded word vector; s3, performing clustering analysis on the embedded word vector by using a Kmeans clustering algorithm to obtain a clustering result; s4, using a KNN model to classify the anonymous users embedded in the word vectors, and marking corresponding labels to obtain labels of all the users; and S5, constructing a user portrait model according to the embedded word vector, the clustering result and the label of the user. False users can be effectively deleted, the authenticity of data is improved, and an accurate and real-time user portrait model is constructed.

Description

technical field [0001] The invention belongs to the field of recommendation algorithms, and relates to a user portrait construction method, system, device and storage medium. Background technique [0002] Alan Cooper, the "Father of Interaction Design", put forward the concept of user portrait. Alan Cooper believes that user portrait is a virtual representation of real users and a target user model based on a series of real attribute data. User portrait is to build a user tag system based on the real information of a large number of users, characterize the user's basic data, behavior data and interests to form a virtual user model, which will fully and dynamically represent a real user. User portraits play a crucial role in the recommendation system, and an excellent user portrait will greatly improve the recommendation efficiency of the recommendation system. User portraits can be divided into the following four genres: [0003] (1) User portrait behavior genre [0004] ...
