Handling KDD Process Changes by Incremental Replanning

Within the framework of our GLS (Global Learning Scheme) system that is a multi-strategy and cooperative KDD (Knowledge Discovery in Databases) system, this paper reports new research progress, by addressing one deeper issue concerning KDD process planning: change management, and giving our solution for it. The problem on change management can be largely solved by an incremental replanning technique. With the issue being properly handled, the GLS system is more complete in KDD process modeling, and more flexible and robust for practical use.
