摘要：

This paper presents a new approach to the summarization of linguistic data. A fuzzy mean, or average, for linguistic data is defined. Linguistic approximation is used to label the average membership function computed using the definition. A measure of variation of the data, a fuzzy variance, is defined. Using the fuzzy variance and the range of the fuzzy data, a normalized measure of dispersion is constructed. A method for labeling this normalized measure is provided using linguistic approximation. Thus the concepts of mean, variance and range are extended to the theory of fuzzy sets and the values obtained are interpreted in a linguistic fashion. Examples illustrate each of these concepts. © 1990.
