KD(D&K): A New Knowledge Discovery Process Model for Complex System
面向复杂系统的知识发现过程模型KD(D&K)及其应用

Based on double bases cooperating mechanism and double-basis fusion mechanism, as well as process models of KDD and KDK, we propose KD (D&K), which is a new KDD(Knowledge discovery in database) process model for complex systems. KD (D&K) integrates the above two mechanisms and the two process models synthetically. This paper discusses the overall flow, the dynamic knowledge base system of KD (D&K), and the application of KD(D&K) to fertilization and plant protection.
