Abstract: For digitalization of traditional Chinese medicine (TCM), research is being conducted on objectivization of diagnosis and treatment, mathematical models of TCM theories, and application of modern information technology to digitize the vast amounts of existing information. However, the author believes that TCM practitioners should first conduct a systematic and comprehensive refined analysis on the knowledge of TCM and unify data elements used in computer intelligence to avoid ambiguity. Thus, we must overcome the epistemological constraints and carefully analyze the relationship among data elements to achieve systematic results and administer TCM appropriately.
