Abstract

This paper presents a new method for constructing nested rough set approximations in information systems. Our approach uses the notion of dependency of attributes in information systems. We begin with the notion of nested sequence of indiscernibility relations that can be defined from the dependency of attributes in information systems. With this notion, we can easily construct nested rough set approximations. In addition, we present the property of accuracy of approximation of sets in information systems.
