Abstract
This paper presents two kinds of rough set approximation definition based on neighborhood system, comparison of some kinds of approximation, and analysis of their related properties. Adopting Pawlak´s method to measure the accuracy in three approximation definitions, that is, Lin´s definition and two definitions presented in this paper. The conclusion is that the first approximation definition presented in this paper is more accurate than the other two.
