Three-way Decisions with Evaluative Linguistic Expressions
Stefania Boffa Davide Ciucci
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.
