"The aim of this book is to report on recent results pertaining to genuinely logical aspects of fuzzy sets in relation to algebraic considerations, to knowledge representation and commonsense reasoning. It is the first one to propose a state-of-the-art glance at the current status of multiple-valued and fuzzy set-based logics, in an Artificial Intelligence perspective. This volume gathers recent surveys or contributions written by many leading contributors in fuzzy sets, logics and artificial intelligence." "This book will be of interest to scholars and graduate students in logics, algebra, knowledge representation and formal aspects of artificial intelligence."--Jacket.
