Acquiring case adaptation knowledge: a hybrid approach
David B. Leake, Andrew Kinley, David C. Wilson · 1996
The ability of case-based reasoning (CBR) systems to apply cases to novel situations depends on their case adaptation knowledge. However, endowing CBR systems with adequate adaptation knowledge has proven to be a very difficult task. This paper describes a hybrid method for performing case adaptation, using a combination of rule-based and case-based reasoning. It shows how this approach provides a framework for acquiring flexible adaptation knowledge from experiences with autonomous adaptation and suggests its potential as a basis for acquisition of adaptation knowledge from interactive user guidance. It also presents initial experimental results examining the benefits of the approach and comparing the relative contributions of case learning and adaptation learning to reasoning performance. Introduction Case adaptation plays a fundamental role in the flexibility of case-based reasoning systems. The ability of CBR systems to solve novel problems depends on retrieving relevant prior sol...
