Fuzzy ontology and information granulation: An approach to knowledge mobilisation

In order to find a common conceptual framework to address the problems of representation and management of imprecise and vague knowledge in a semantic web we have analysed the role played by information granulation in human cognition. Fuzzy granulation underlies the basic concepts of linguistic variable and fuzzy if-then rules, which play a major role in the applications of fuzzy logic to the representation and treatment of imprecision and vagueness. Fuzzy information granulation is central to fuzzy logic because it is central to concept formation in human reasoning and to the design of intelligent systems, and therefore is central to the modelling of fuzzy ontologies. © Springer-Verlag Berlin Heidelberg 2010.
