Abstract: Objective: Based on analysis association rules mining model data for the liver disease of traditional Chinese medicine (TCM), to search for relation between checking index and the Chinese medicine dialectical. Method: By setting the minimum support and minimum confidence, we used association rules to analyze the patients’ data for the liver disease of traditional Chinese medicine. According to the importance of generated rules, we screened out the rules which are positively correlated to the before and after rule, and evaluated the accuracy of the mining results with the lift chart. Result: Through the analysis of 317 samples, 48 rules are received, which reveals the relationship between the check index combination and TCM syndrome differentiation results. Conclusion: Using association rules in electronic medical record data analysis for the liver disease of TCM can reveal the influence of different examination indexes for TCM syndrome differentiation, and is advantageous to the auxiliary diagnosis.
