Abstract
Granulation of a universe involves grouping of similar elements into granules. With granulated views, we deal with approximations of concepts, represented by subsets of the universe, in terms of granules. This paper examines the problem of approximations with respect to various granulations of the universe. The granulation structures used by rough set theory, neighborhood systems and topological space and the corresponding approximation structures, are studied.
