KurzfassungAbstract
In this paper, we present a decidability result for entailment of conjunctive queries (CQs) in the very expressive Description Logic (DL) ALCHOIQb by establishing nite representability of countermodels in case the query given as input is not entailed. Our results also generalize to unions of conjunctive queries, and to SHOIQ and SROIQ provided the query contains only simple roles.
