Future work include design a knowledge library, which uses knowledge to describe the data mining component, to support the data mining component library, a rule library, which can modify flexibly and easily, a scheme library based on CRISP-DM data mining process, and a key-word library for
component retrieval. By using the inference engine of the knowledge library and the rule library, we can design the recommendation strategies for data mining components. It realizes the control of knowledge library in the application and development process of data mining.
