提出了一种优化的owl2查询重写算法,该算法通过避免不必要的推理和扩展子句的包含检查来计算用户查询的重写集。与其他类似方法相比,该评估显示了显著的性能改进。或者,该算法可以生成等效的非递归数据表程序,而不是重写集。
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.
