Detection of Herb-Symptom Associations from Traditional Chinese Medicine Clinical Data

Figure 5

Distribution of symptom similarity and herb similarity of GPBT/INSOMNIA/TS/CHF: the -axis represents “Herb/symptom similarity bins,” and -axis represents “Number of patient-pairs.” The yellow column shows the symptom similarity data, while green column shows the herb similarity data. Most of the patient cases in GPBT and INSOMNIA data sets are in low symptom similarity and herb similarity (0.2 is the similarity in most cases), while the other two data sets both have much higher symptom and herb similarities (0.3 is the similarity in most cases for herbs and 0.5 or 0.7 is the similarities for symptom). Furthermore, there are clear disparities between herb similarity distribution and symptom similarity distribution in the latter two data sets.
