摘要

我们考虑了一类线性查询程序和完整性约束，并开发了(i)计算残数和(ii)将它们推入递归程序的方法，以最小化冗余计算和运行时开销。我们还讨论了我们的策略在智能查询应答中的应用。

Pushing semantics inside recursion: A general framework for semantic optimization of recursive queries

We consider a class of linear query programs and integrity constraints and develop methods for (i) computing the residues and (ii) pushing them inside the recursive programs, minimizing redundant computation and run-time overhead. We also discuss applications of our strategy to intelligent query answering.<>
