Embodiment Construction

[0013] Embodiments of the information pushing method of the present invention will be described below in conjunction with the accompanying drawings.

[0014] figure 1 It is a flow chart of the information pushing method of the present invention. like figure 1 As shown, the information push method may include the following steps:

[0015] S1, extracting feature information of the content to be pushed and historical operation information of the target user from the database, and constructing a content feature vector and a user feature vector respectively according to the feature information and historical operation information;

[0016] The content feature vector can be constructed according to:

[0017] First, the feature information of the content to be pushed can be extracted from the database;

[0018] Then, the content to be pushed can be modeled according to the feature information to obtain a model of the content to be pushed, and the model can include historical feat...

Abstract

The present invention relates to an information push method, comprising the following steps: extracting feature information of content to be pushed and historical operation information of a target user from a database, and constructing a content feature vector and a user feature vector respectively according to the feature information and historical operation information; Calculate the similarity between the target user and other users according to the user feature vector, select a number of similar users similar to the target user from other users according to the similarity, and obtain the similar user's response to each content to be pushed According to the weight, calculate the correlation coefficient of the target user for each content to be pushed according to the weight; predict the popularity of each content to be pushed according to the content feature vector, and modify the correlation coefficient according to the prediction result of the popularity; according to the modified The correlation coefficient of each content to be pushed is sorted, and the corresponding content to be pushed is pushed to the target user according to the sorting result.

Description

technical field [0001] The invention relates to the technical field of machine learning, in particular to an information pushing method. Background technique [0002] The rapid growth of information on the Internet makes it increasingly difficult for users to find valuable information, making information push systems one of the most active academic research fields today. The information push system tries to assist users to discover potentially favorite music, movies, products, apps, etc. [0003] Some information push systems learn based on user information and product information, so that products that users prefer have higher weights. When a large amount of user information is available, the information push system can provide personalized push results. For example, push software books for software workers, and provide art books for art workers. [0004] However, users' interests and preferences change over time in many cases. The current information push system lacks ...
