In case-based reasoning, previous reasoning experiences are used directly to solve new problems and make Inferences,rather than doing those tasks from saatch using generalized methods. One major advantage of a case-based approach is that It can help a reasoner avoid repeating previously-made mistakes. W h e n the case-based reasoner Is reminded of a case in which a mistake was made. It provides a warning of the potential for a mistake. If the previous case was finally solved successfully, it can provide a suggestion of what to do instead. In this paper, w e describe the process by which a case-based reasoner can take advantage of previous failures. W e Illustrate with cases from the domains of common-sense mediation and menu planning and show a program called JULIA reasoning In the domain of menu planning.
