(CBR) Information on situations (cases) is stored with the purpose of recalling cases that are similar to a target problem in order to help solve the problem. People commonly use this approach informally in problem solving and forecasting See analogy.). It can also be used as the basis for designing expert systems by starting with examples rather than with the process. CBR is a term used in the fields of cognitive science and artificial intelligence. The forecasting method of structured analogies could be viewed as one type of CBR. We have been unable to locate any tests of the predictive validity of CBR.
