title = "Rough Set Approach under Dynamic Granulation in Incomplete Information Systems",
abstract = "In this paper, the concept of a granulation order is proposed in an incomplete information system. Positive approximation of a set under a granulation order is denned and its some useful properties are investigated. Unlike classical rough set, this approach focuses on how to describe the structure of a rough set in incomplete information systems. For a subset of the universe, its approximation accuracy is monotonously increasing under a granulation order. This means that a proper family of granulations can be chosen for a target-concept approximation according to user requirements. {\textcopyright} Springer-Verlag Berlin Heidelberg 2007.",
