RT Book, Section T1 On the Semantics of Bipolarity and Fuzziness A1 Rodríguez González, Juan Tinguaro A1 Franco De Los Ríos, Camilo A. A1 Montero De Juan, Francisco Javier A2 Melo-Pint, P. A2 Couto, P. A2 Serôdio, Carlos A2 Fodor, János A2 De Baets, Bernard AB This paper analyzes the relationship between fuzziness and bipolarity, notions which were devised to address different kinds of uncertainty: linguistic imprecision, in the former, and knowledge relevance and character or polarity, in the latter. Although different types of fuzziness and bipolarity have been defined, these relations are not always clear. This paper proposes the use of four-valued extensions to provide a formal method to rigorously define and compare the semantics and logical structure of diverse combinations of fuzziness and bipolarity types. As a result, this paper claims that these notions and their different types are independent and not semantically equivalent despite its possible formal equivalence.
