Abstract
Assuming a set of linguistic preferences representing the preferences of the individuals, a linguistic choice process is presented. This is developed using the concept of fuzzy majority for deriving a collectiv e linguistic preference, and the concept of nondominated alternatives for deriving the selected alternatives in the linguistic choice proces s. The fuzzy majorities are equated with fuzzy linguistic quantifiers. The collective linguistic preference is derived by means of a linguis tic ordered weighted averaging operator whose weights are defined usin g a fuzzy linguistic quantifier. In order to obtain the nondominated a lternatives, we present a novel reformulation of Orlovski's nondominan ce degree under linguistic information.
