Goal-oriented Query Rewriting for OWL 2 QL
24th International Workshop on Description Logics (DL 2011), Barcelona, Spain, 13-16 July 2011
ABSTRACT
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.
