Perspective view of FangNet’s symptom-herb network. A. Herb-herb co-occurrence and Mutual Exclusivity. The triangular heat map is an illustration of co-occurrence and mutual exclusivity for 69 herbs with a frequency more than 0.05. The inner figure on the left is the result of the literature search on CNKI for herbs with significant co-occurrence and mutual exclusivity. 17 Herb pairs on the left with light green background are those herbs with high co-occurrence. 10 herb pairs on the right with light red background are those herbs with high mutual exclusivity. B. Symptom-herb network with 813 herb-herb and 76 symptom-herb edges. C. 76 high confidence symptom-herb associations.
