Knowledge graph is the main content in education, and strengthening the knowledge graph analysis of higher education and improving knowledge relevance has become the main problem of research. However, there is a problem of over-analysis of knowledge in higher education, so the integration of intelligent analysis methods into it and the strengthening of knowledge graph analysis are the focus of this paper. The results show that there is an inevitable relationship between knowledge graph and education, and the improvement rate of knowledge structure and knowledge content is greater than 85%. At the same time, it also promotes the optimization of knowledge structure, with a promotion rate of 20%. Therefore, it is necessary to strengthen the analysis of knowledge graphs, optimize the knowledge structure, and form comprehensive knowledge content.
