Linguistic majorities with difference in support
A new linguistic aggregation rule that extends numerical majorities based on difference in support is introduced. Linguistic majorities with difference in support are formalised for fuzzy set and 2-tuples. Both representations are proved to be mathematically isomorphic. A set of normative properties have been demonstrated to hold for the new linguistic majorities.
