More general forms of the paper by O. Kazanci and S. Yamak (Generalized fuzzy bi-ideals of semigroups, Soft Comput. 12, 1119-1124, 2008) are discussed. The notion of (epsilon, epsilon V q kappa)-fuzzy hi-ideals in a semigroup S is introduced, and several properties are investigated. Characterizations of an (epsilon, epsilon V q kappa)-fuzzy bi-ideal in a semigroup S are discussed.
