%0 Book Section %T Information Measures over Intuitionistic Four Valued Fuzzy Preferences publisher IEEE %D 2010 %U 978-1-4244-6920-8 %@ https://hdl.handle.net/20.500.14352/45337 %X This paper studies the meaning of fuzzy preference under the light institionistic fuzzy sets. Intuitionism is revisted and intuitionistic fuzzy prefrerence relations are defined. A linguistic interpretation of strict and weak fuzzy preference is then developed where indecision can be explicity analyzed with the help of a bilattice. Uncertainty is finally examined as a measure of ignorance associated to the intensity value of thhe preferece predicate, where some information measures are applied over its complete structure. %~
