KDIST: a development environment for knowledge discovery system

The paper presents a universal development environment of application domain-oriented knowledge discovery system - KDIST. Based on graphic modeling and intelligent guidance techniques, KDIST is user-friendly enough for generic people to develop a knowledge discovery system with expertise as little as possible. Not only discovering knowledge from data with high performance, but can the developed knowledge discovery system add discovered knowledge to a relative knowledge base and then refine knowledge on the premise of keeping consistence of the knowledge base.
