The relationship between object level intuitionistic
fuzzy sets and predicate based intuitionistic fuzzy sets is
explored. Mass assignment uses a process called semantic unification
to evaluate the degree to which one set supports another,
the inverse function is semantic separation. Intuitionistic fuzzy
sets are mapped onto a mass assignment framework and the
semantic unification operator is generalised to support both
mass assignment and intuitionistic fuzzy sets, as is semantic
separation. Transfer of inconsistent and contradictory evidence
are also dealt with
