How much is " about " ? Fuzzy interpretation of approximate numerical expressions

Abstract : Approximate Numerical Expressions (ANEs) are linguistic expressions involving numbers and referring to imprecise ranges of values , such as " about 100 ". This paper proposes to interpret ANEs as fuzzy numbers. A model, taking into account the cognitive salience of numbers and based on critical points from Pareto frontiers, is proposed to characterise the support, the kernel and the 0.5-cut of the corresponding membership functions. An experimental study, based on real data, is performed to assess the quality of these estimated parameters.
