Problems solved by technology

At the other level, knowledge graph technology is usually used to extract the relationship between entities, and in the knowledge system of the course, it is necessary to extract multiple related relationships such as knowledge points, knowledge concepts, and course names. There is an essential gap between the two concepts, so the effect extremely bad

Abstract

The invention relates to the technical field of big data analysis, and provides a course knowledge graph construction method and a device, a terminal and a storage medium, and the method comprises thesteps: extracting domain keywords from full text data, combining the domain keywords into keyword pairs at will, and calculating the co-occurrence features of the keyword pairs in a same text data; clustering the keyword pairs according to the co-occurrence features, and screening out a plurality of forward keyword pairs; determining a first keyword as a first-level knowledge point and determining a plurality of second keywords and a plurality of second-level knowledge points corresponding to the first keyword based on the plurality of forward keyword pairs; extracting problem points corresponding to each knowledge point and extracting related courses corresponding to the knowledge points; and constructing a course knowledge graph according to the knowledge points, the problem points andthe related courses, and recommending the courses. The method can be applied to smart education, and the course knowledge graph is established to improve the course recommendation quality and efficiency. In addition, the invention also relates to the block chain technology, and the course knowledge graph is stored in a block chain node.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a method, device, terminal and storage medium for constructing a course knowledge graph. Background technique [0002] With the development of mobile networks, online education has become more and more popular. The number of online education courses has been greatly enriched, and the teaching direction has also been greatly expanded. In the application scenario of online education, there are a large number of scattered and uploaded courses, and there is a lack of continuity between courses. After learning a course, facing an unfamiliar knowledge system, it is difficult for users to choose knowledge step by step for learning. Therefore, for the vast ocean of knowledge, extracting a knowledge system composed of knowledge points is beneficial for users to acquire knowledge in a targeted manner. At the same time, having a complete knowledge system is also conducive...
