In this paper, taking account of an information retrieval in connection with sensitive information such as fine arts, the authors discuss quantitative verifica-tion of synonymous relations among sensitive words in their thesaurus. For instance, the criticism or apprediation of fine art are often emotiona, subjective, and sensitive so that sensitive words are frequently used as keywords in the informa-tion retrieval. However, because a sensitive word has many complicate and fuzzy synonyms, it is inevitable to control the information retrieval by fuzzy thesaurus. In this paper, regarding a sensitive word as a fuzzy set of stimula-ting events, the authors formulate the experimental method to quantify the fuzzy synonymous relations among sensitive words by "a membership function" and "a coefficient of the synonymous relation". The characteristics of this method is to cellect subjective's reaction of sensitive workds to a series of stimulating events, and analyze those data to estimate the fuzzy synonymous relation among sensitive words. The results contributes to the fuzzy synonymous thesaurus of sensitive words to the sensitive information retrieval of a fuzzy database.
