If what you are interested in is hiding those concepts from the *users*,
you could simply import the ontology, then use an AnnotationProperty to
tell your application which concepts to show and which ones to hide.
If you want to hide them from the inference engine as well, this is
another story, because it may have some unexpected consequences. For
example, considering the ontology:
Animal
Mammal
Dog
Cat
if you decide that Mammal is not interesting for you, you may lose the
relation between Animal and Dog/Cat. Note that [1] gives some
interesting solutions to this kind of problem.
