Qualitative definition is a term coined by Ashu M. G. Solo to refer to a linguistic definition of an imprecise word without numerical parameters, such as is found in dictionaries, instead of a definition of an imprecise word using a crisp set or fuzzy set (quantitative definition). All of these terms were coined by Solo.

Abstract
Fuzzy logic can deal with information arising from perception and cognition that is uncertain, imprecise, vague, partially true, or without sharp boundaries. Fuzzy logic can be used for assigning linguistic grades and for decision making and data mining with those linguistic grades by teachers, instructors, and professors. Many aspects of fuzzy logic including fuzzy sets, linguistic variables, fuzzy rules, fuzzy math, fuzzy database queries, computational theory of perceptions, and computing with words are useful in uncertainty management of linguistic evaluations for students. This chapter provides many examples of this after describing the theory of fuzzy logic.
