Collective choice rules under linguistic preferences: an example of the computing with words/perceptions paradigm

Originally, most of the popular group decision making rules were conceived for classical (crisp) preference relations (orderings), and then extended to the case of traditional fuzzy preference relations. We propose to further extend them to linguistic preference relations. A Linguistic OWA operators guided aggregation of preferences is employed. The approach proposed is an example of the use of the new paradigm of computing with words/perceptions.
