摘要:

基于结果的演算是描述逻辑(DL)的一系列推理算法,它们以一种通常在实践中实现优异性能的方式结合了超表和分辨率。然而,到目前为止,它们被提议用于Horn DL(不支持析取)或不计数量词的DL。在本文中,我们提出了一种新的基于结果的演算SRIQ-一个丰富的DL,支持这两个功能。这个扩展是不平凡的,因为中间的结果,需要在推理过程中得出不能使用DL本身捕获。我们初步的性能评估结果表明,我们的方法在实践中的可行性。

英文摘要:

Consequence-based calculi are a family of reasoning algorithms for description logics (DLs), and they combine hypertableau and resolution in a way that often achieves excellent performance in practice. Up to now, however, they were proposed for either Horn DLs (which do not support disjunction), or for DLs without counting quantifiers. In this paper we present a novel consequence-based calculus for SRIQ---a rich DL that supports both features. This extension is non-trivial since the intermediate consequences that need to be derived during reasoning cannot be captured using DLs themselves. The results of our preliminary performance evaluation suggest the feasibility of our approach in practice.
