Weak knowledge point identification method and learning path planning method and device

Abstract

The invention provides a weak knowledge point recognition method and a learning path planning method and device.The recognition method comprises the steps that a user portrait of a target user is determined based on test question representation of all test questions in historical answer records of the target user and historical score conditions, corresponding to all the test questions, of the target user; based on the user portrait of the target user, determining similar users of the target user; and determining weak knowledge points of the target user based on the answer score condition corresponding to each knowledge point of the similar user. According to the identification method, the planning method and the device provided by the invention, the problem of increasing the question answering workload of the user is avoided, meanwhile, the contingency of the user when the user answers the evaluation question is also avoided, the accurate identification of the weak knowledge points of the user is realized, the user is helped to carry out targeted learning, and in addition, the user experience is improved. And personalized learning resource recommendation for weak knowledge points can be carried out subsequently, and the interpretability and acceptability of learning resource recommendation are improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method for identifying weak knowledge points, a method and a device for planning a learning path. Background technique [0002] With the advent of the Internet and the era of big data, the process of education informatization continues to deepen, and online education has emerged as the times require. Different from the traditional live broadcast class mode, AI (Artificial Intelligence, artificial intelligence) interactive classes do not require the full participation of the lecturer, and dynamically use video teaching, exercise training and other methods to guide students to participate in the interaction, so that students can learn the key and difficult points of the course efficiently, and cultivate The ability of students to learn consciously. [0003] In the interactive teaching process of existing AI interactive courses, evaluation links are usually set up, and students...
