We present an optimized query rewriting algorithm for OWL 2 QL that computes the rewriting set of a user query by avoiding unnecessary inferences and extended clause subsumption checks. The evaluation shows a significant performance improvement in comparison to other similar approaches. Alternatively, instead of a rewriting set, the algorithm can produce an equivalent non-recursive datalog program.
