Reasoning about multiple aspects in DLs: Semantics and Closure
  Construction
  Starting from the observation that rational closure has the undesirable
property of being an "all or nothing" mechanism, we here propose a
multipreferential semantics, which enriches the preferential semantics
underlying rational closure in order to separately deal with the inheritance of
different properties in an ontology with exceptions. We provide a
multipreference closure mechanism which is sound with respect to the
multipreference semantics.
