Three-way Decisions with Evaluative Linguistic Expressions

TL;DR

This paper introduces a linguistic framework for three-way decisions by utilizing evaluative linguistic expressions, establishing new links between decision theory and natural language semantics.

Contribution

It presents a novel approach to three-way decision-making by incorporating evaluative linguistic expressions, bridging two distinct research areas.

Findings

Established connections between three-way decisions and evaluative linguistic expressions.

Proposed a method to construct decision regions using natural language expressions.

Highlighted potential applications in decision support systems.

Abstract

We propose a linguistic interpretation of three-way decisions, where the regions of acceptance, rejection, and non-commitment are constructed by using the so-called evaluative linguistic expressions, which are expressions of natural language such as small, medium, very short, quite roughly strong, extremely good, etc. Our results highlight new connections between two different research areas: three-way decisions and the theory of evaluative linguistic expressions.
