Modelling Comparative Concepts in Conceptual Spaces

Abstract

The conceptual spaces approach has emerged as a new and powerful way of thinking about concepts. In earlier work, the present authors have addressed the question of how to model vague concepts in the conceptual spaces framework. That in turn was instrumental in Decock's and Douven's account of a graded membership relation in further work. In this paper, we make use of the account of graded membership to present a way of modelling comparative concepts in conceptual spaces. Finally, Dietz' alternative account of comparative concepts is contrasted with the presented Decock---Douven type account.
