− | In general, the three domains of a sign relation can be any sets whatsoever, but the kinds of sign relations that are contemplated in a computational framework are usually constrained to having '''I''' ⊆ '''S'''. In this case, interpretants are just a special variety of signs, and this makes it convenient to lump signs and interpretants together into a single class called the ''syntactic domain''. In the forthcoming examples, '''S''' and '''I''' are identical as sets, so the very same elements manifest themselves in two different roles of the sign relations in question. When it is necessary to refer to the whole set of objects and signs in the union of the domains '''O''', '''S''', '''I''' for a given sign relation '''L''', one may refer to this set as the ''world of '''L''''' and write '''W''' = '''W'''<sub>'''L'''</sub> = '''O''' ∪ '''S''' ∪ '''I'''. | + | In general, the three domains of a sign relation can be any sets whatsoever, but the kinds of sign relations that are contemplated in a computational framework are usually constrained to having ''I'' ⊆ ''S''.

For signs in general, neither the existence nor the uniqueness of a denotation is guaranteed. Thus, the denotation of a sign can refer to a plural, a singular, or a vacuous number of objects. In the pragmatic theory of signs, these references are formalized as certain types of dyadic relations that are obtained by projection from the triadic sign relations. | | One aspect of semantics is concerned with the reference that a sign has to its object, which is called its ''denotation''.
