Input: This paper presents a five-valued representation of bifuzzy sets. This representation is related to a five-valued logic that uses the following values: true, false, inconsistent, incomplete and ambiguous. In the framework of fivevalued representation, formulae for similarity, entropy and syntropy of bifuzzy sets are constructed.
