In BBN's natural language understanding and generation system (Janus), we have used a hybrid approach to representation, employing an intensional logic for the representation...

We prove co-N2ExpTime-hardness for conjunctive query entailment in the description logic ALCOIF , thus improving the previously known 2ExpTime lower bound. The result transfers to ...
