A KDD experience factory: Using textual CBR for reusing lessons learned

Abstract

We introduce an integrated framework for Knowledge Discovery in Databases (KDD) and Knowledge Management and show how Knowledge Management can complement KDD. Specifically, we examine methods how to improve the knowledge intensive and weak structured process of KDD through the use of an experience factory using the method of experience packaging and case based reasoning (CBR). This paper investigates how knowledge contained in the textual components of experience packages can be used to improve the retrieval of lessons learned in KDD. We add textual CBR techniques to our CBR approach in order to improve the case retrieval mechanism of the experience factory. Our technique exploits domain-specific knowledge contained in the textual parts of the packages to find better reuse candidates of lessons learned in KDD.
