Based on my knowledge, some Description Logics include the constructor for role complement, while some others don't.

OWL DL doesn't support  role (i.e. property) complement, the language designers (of OWL DL) may consider the issue of computational complex (as well as the decidability problem). 

Maybe, somebody can give us the right answer.
