document: Definition of a similarity measure between cases based on auto/cross-fuzzy thesauri A similarity measure between cases is needed in order to evaluate the degree of similarity when using past similar cases in order to resolve current problems . In similar case retrieval , multiple indices are set up in order to characterize the queries and individual cases , then terms are given as values to each . The similarity measure between cases commonly used is defined using the rate at which the values provided from the corresponding indices match . In practice , however , values can not be expected to be mutually exclusive . As a result , a natural expansion of this approach is to have relationships in which mutually similar meanings are reflected in the similarity measure between cases . In this paper the authors consider an auto-fuzzy thesaurus which gives the relationship for values between corresponding indices and a cross-fuzzy thesaurus which gives the relationship for values between mutually distinct indices , then defines a similarity measure between cases which considers the relationship of index values based on these thesauri . This definition satisfies the characteristics required for the operation of case-based retrieval even when one value is not necessarily given in the index . Finally , using a test similar case retrieval system , the authors perform a comparative analysis of the proposed similarity measure between cases and a conventional approach
