Abstract
This paper presents a framework for the formulation, interpretation, a nd comparison of neighborhood systems and rough set approximations usi ng the more familiar notion of binary relations. A special class of ne ighborhood systems, called 1-neighborhood systems, is introduced. Thre e extensions of Pawlak approximation operators are analyzed. Propertie s of neighborhood and approximation operators are studied, and their c onnections are examined. (C) 1998 Elsevier Science Inc. All rights res erved.
