嵌套正则表达式的包容性
Containment of Nested Regular Expressions
摘要:
嵌套正则表达式(NRE)已被提出作为一个强大的形式主义查询RDFS图,但在一个更一般的图数据库上下文中的研究一直很少,目前缺乏静态分析的结果。在本文中,我们研究了NRE的包容问题,并表明它可以在PSPACE中解决,即,与包含正则表达式或正则路径查询(RPQ)的问题相同的复杂性。
英文摘要:
Nested regular expressions (NREs) have been proposed as a powerful formalism for querying RDFS graphs, but research in a more general graph database context has been scarce, and static analysis results are currently lacking. In this paper we investigate the problem of containment of NREs, and show that it can be solved in PSPACE, i.e., the same complexity as the problem of containment of regular expressions or regular path queries (RPQs).
