§16§This book explores reasoning with rough sets by developing a granularity-based framework. It begins with a brief description of the rough set theory, then examines selected relations between rough set theory and non-classical logics including modal logic. In addition, it develops a granularity-based framework for reasoning in which various types of reasoning can be formalized. The book will be of interest to all researchers whose work involves Artificial Intelligence, databases and/or logic. §04§Introduction.- Rough Set Theory.- Non-Classical Logics.- Logical Characterizations of Rough Sets.- A Granularity-based Framework of Reasoning.- Conclusions.
