%A Varol Akman %A Mujdat Pakkan %J Journal of Intelligent Information Systems: Integrating Artificial Intelligence and Database Technologies %T Nonstandard Set Theories and Information Management %X The merits of set theory as a foundational tool in mathematics stimulate its use in various areas of artificial intelligence, in particular intelligent information systems. In this paper, a study of various nonstandard treatments of set theory from this perspective is offered. Applications of these alternative set theories to information or knowledge management are surveyed. %N 1 %K ZF (Zermelo-Fraenkel) set theory, knowledge representation, AFA (anti-foundation axiom), information management, commonsense reasoning, commonsense set theory, situation theory, nonwellfounded sets (hypersets). %P 5-31 %V 6 %D 1996 %L cogprints465
