With the full use of syndrome differentiation theory and making the best of the treatment of medicated diet, the dietetic therapy of traditional Chinese medicine is devoted to harmonize the Yin, Yang, Qi, blood within the human body, to improve human body´s health effectively. In this paper, we proposed an improved information gain method based on information gain method and TF-IDF method to express symptoms and mine the relationship between symptoms and category of medicated diet. According to the given symptom sets, it got the most suitable and likely category of medicated diet. In this way, it could simulate the diagnosis of the dietetic therapy of traditional Chinese medicine. The results show that the improved information gain method is more effective than information gain method and TF-IDF method on the expression of symptoms and can improve the accuracy of classification.
