  In this paper we develop a concept aware multi-preferential semantics for
dealing with typicality in description logics, where preferences are associated
with concepts, starting from a collection of ranked TBoxes containing
defeasible concept inclusions. Preferences are combined to define a
preferential interpretation in which defeasible inclusions can be evaluated.
The construction of the concept-aware multipreference semantics is related to
Brewka's framework for qualitative preferences. We exploit Answer Set
Programming (in particular, asprin) to achieve defeasible reasoning under the
multipreference approach for the lightweight description logic EL+bot.
  The paper is under consideration for acceptance in TPLP.
