The OWL 2 QL profile, which is based on DL-LiteR, has been designed so that query answering is possible using relational database technology via query rewriting. Unfortunately, given a query Q posed in terms of an OWL 2 QL ontology O, the size of the rewritten query, Qo, which can be evaluated directly on the relational database, is worst case exponential w.r.t the size of Q and O . This means that the computation and evaluation of Qo can be costly. Recent research focuses on creating rewriting algorithms that generates Qo with a smaller size .
