# The concept of a linguistic variable and its application to approximate reasoning - I

@article{Zadeh1975TheCO, title={The concept of a linguistic variable and its application to approximate reasoning - I}, author={L. Zadeh}, journal={Inf. Sci.}, year={1975}, volume={8}, pages={199-249} }

By a linguistic variable we mean a variable whose values are words or sentences in a natural or artificial language. I:or example, Age is a linguistic variable if its values are linguistic rather than numerical, i.e., young, not young, very young, quite young, old, not very oldand not very young, etc., rather than 20, 21, 22, 23, In more specific terms, a linguistic variable is characterized by a quintuple (&?, T(z), U, G,M) in which &? is the name of the variable; T(s) is the term-set of2… Expand

Fuzzy Logic and the Resolution Principle

It is proved that, in fuzzy logic, a set of clauses is unsatisfiable iff it is unsatisfiability in two-valued logic, and it is also shown that if the most unreliable clause of aSet of clauses has a truth-value a>0.5, then all the logical consequences obtained by repeatedly applying the resolution principle has truth- value never smaller than a.
