| Abstract: | In recent years， knowledge graph and personalized recommendation technology have been the focus of attention of educational researchers. How to make use of the dual advantages of knowledge graph and personalized recommendation technology to help learners build knowledge system and improve learning effect is the focus of this paper. This paper realizes the association analysis of knowledge elements through the construction of domain knowledge graph， and makes personalized recommendation of learning resources with the help of learner portrait analysis. It forms the association recommendation model of learning resources based on knowledge graph， which links learner-learning resources-knowledge elements. On this basis， two classes of “Analog Electronic Technology Foundation” （named A and B） are selected to verify the learning effect. The experimental data prove that the proposed learning resource association recommendation model based on knowledge graph can improve the learning effect of electro-analog to a certain extent. |
