Modeling of fuzzy data

Abstract

Fuzzy data are imprecise data obtained from measurements, perception or by interviewing people. Typically, those data are expressed in linguistic terms (in qualitative form). For example, \"Tony is young\", is a useful information, and yet it is not quite clear how we could model it mathematically for processing. The adjective young is intended to give an elastic constraint on the unobservable variable X (age of Tony), the range of X is [0, 100], say. © Springer-Verlag Berlin Heidelberg 2006.
