Problems solved by technology

[0005] However, the above user portraits cannot reflect the user's needs for courses
When users need to know which courses in the online education system meet their needs, or when the operator needs to carry out targeted promotion for a certain user, such user portraits cannot provide help
In addition, the above-mentioned user portraits are mainly calculated based on the user's learning situation, and the statistical process hardly considers the subject of the course itself, so it is difficult to reflect the theme relevance between courses, making it impossible for the operator to promote related courses based on it

Abstract

The present invention discloses a user portrait construction system and a method thereof. The user portrait construction system includes forming a corresponding theme distribution matrix of documentsby acquiring keywords of description documents, clustering description documents based on the theme distribution matrix of documents, forming a binomial tree with courses as leaf nodes and clusteringkeywords as father nodes in each layer by using a tree map formation module which can form a tree map reflecting the theme relevance between the courses based on the theme discovery, and further obtaining the user portrait including a plurality of clustering keywords as labels according to the courses purchased by users. The user portrait can effectively reflect the needs of users for online courses, so that users can understand what courses in online education system meet their needs and operators can carry out promotion to target users.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a system and method for constructing user portraits used in the field of online education. Background technique [0002] In various network service systems, user description and positioning are the key to accurate service and promotion. At present, there are many ways to describe user characteristics, one of which is to construct user portraits. The user portrait contains multiple tags that can reflect the characteristics of the user's needs. When users browse the website or purchase services, they can further understand their own needs through the visually displayed tags. When constructing a user portrait, the usual method is to collect information such as the user's personal data, access records, and operation history, and obtain the user's characteristics in multiple dimensions through statistics and machine learning, and then synthesize them to obtain a user portrait. ...
