In order to fully understand the research status in the field of knowledge tracking based on deep learning in China, this paper uses CiteSpace visualization analysis software to conduct visualization analysis and text analysis on 118 literatures with the theme of "knowledge tracking based on deep learning" included in CNKI from 2012 to 2022. The results show that "artificial intelligence", "intelligent education", "deep learning" and "big data" are the research hotspots of knowledge tracking based on deep learning in China. The correlation between its frontier research and the development of the times rose rapidly from 2017 to 2021. In the future research, researchers should focus on the optimization of the model, the application of basic research and the practical application of the research results.
