CBG - ”Casebase Generator” is a decision support system recently developed at Department of Mathematics and Informatics, University of Novi Sad. The technology used for implementing this system is Case-Based Reasoning (CBR). CBR is relatively new and promising area of artificial intelligence where every new problem is solved by adapting the solutions of the previously successfully solved problems. In the past few years CBR has become a popular technique for knowledge-based systems in different domains because the experience is included in solving every new problem. The purpose of this system is to be the main engine of some future, more specialized systems. ”Case Base Generator” system is partly described in this paper and some future specialization are analyzed.
