Abstract

The concept of a linguistic variable, first introduced by Zadeh [5], is here modified and reinterpreted with the aim of producing a computationally more manageable model of natural human reasoning with linguistic imprecision. An important characteristic of the new interpretation is that it establishes the meaning of linguistic terms relative to a context comprised of the available atomic linguistic terms. This in turn leads to a formal distinction between the precision of linguistic terms and their specificity.

A future work is planned wherein the new formulation will be explored as the possible basis for an intuitively plausible semantics for Horn clauses. It is hoped that this will yield a viable approach to approximate reasoning in various kinds of automated deduction systems.
