ESTEEM, from Esteem Software Inc., is written in Intellicorps Kappa-PC and is now in version 1.4. ESTEEM can Kappas inference engine, thus enabling developers to create adaptation rules. It supports applications that access multiple case-bases and nested cases. This means that one can reference another case-base through an attribute slot in a case. ESTEEM supports various similarity assessment methods including feature counting, weighted feature computation, inferred feature computation. It also can automatically generate feature weights, either using an ID3 weight generation method, or a gradient descent weight generation method. Moreover, users can incorporate their own similarity functions into ESTEEM if they wish. ESTEEM is very reasonably priced and is well suited as a teaching tool or an entry level CBR product.
