A Framework for Case-Based Diagnosis
Yoshiteru Ishida, Hidekatsu TOKUMARU · Transactions of the Society of Instrument and Control Engineers · 1990
Dynamic memory organization has been proposed by R.C. Schank which allows content addressing in a case base.Case-based reasoning on the dynamic memory proceeds in the following two steps: (1) For the problem solving of the given case, find the nearest cases in the case-base, (2) transform the cases so that the information in the case is applicable to the current case.In this paper, we first introduce the mechanism to drive the dynamic organization of the memory.In the memory, knowledge is represented by the frame which is structured to maintain the number of slots small by sharing the common attribute-values among cases.An architecture for case-based diagnosis is presented, using the memory organization where diagnostic cases are indexed both by the symptoms and by the causal relation among symptoms.The program CAOS (CAse Operation System) is implemented for the process diagnosis domain.
