The application of modern technologies such as big data and artificial intelligence in life and work has inspired scholars to apply them to Chinese medicine diagnosis. And the application of big data is just the right way to digitise and organise and classify millennia of knowledge, experience and literature on Chinese medicine diagnosis. Based on this, the robot will be made intelligent through artificial intelligence-related technology, thus promoting the transmission, development and innovation of Chinese medicine diagnosis. In this paper, the literature is obtained by searching the title "Big Data TCM" or "Artificial Intelligence TCM" on CNKI. The obtained literature was read, analyzed and summarized in order to provide theoretical help for further realizing the objectification of TCM diagnosis.
