A Classified Herbs Method and Searching Algorithm of Classification Tree Used for Mathematical Measurement of Effect

It´s the fundamental guarantee of intelligent mining curative efficacies of prescriptions to establish mathematical models, which transforms data in a prescription into reflection of essential intensity of effect. As we know, logical classification based on characteristics of herbs is a necessary precondition to design measuring models indicating essential effect of any herb. This paper proposes a natural classification method, whereby complexity of classification is largely decreased, and requirements required by measuring effect of any herb are satisfied. Through discussion on equivalence characteristic attributes of herbs and dosage, as well as implicative relevancy of dosage range and dosage, this paper presents algorithms of classifying herbs, used for intelligent mining of efficacies of Chinese Medicine Prescriptions, which can help to achieve automatically implementation of classified herbs in practice.
