选言逻辑程序良基语义的比较与计算

Comparisons and Computation of Well-founded Semantics for Disjunctive Logic Programs

Kewen Wang, Lizhu Zhou

摘要:

在将良基语义扩展到一般的析取逻辑程序方面已经做了大量的工作,并提出了各种方法。然而,这些语义彼此不同,并且对于哪个语义是最意图的没有达成共识。在本文中,我们从不同的角度来看待析取良据推理。我们表明,有一个直观的形式的良基推理的析取逻辑编程,其特征在于通过稍微修改的一些定义析取良基语义,包括程序转换,论证,无基集(和解决方案的过程)的构造方法。我们还提供了一个自底向上的过程,这种语义。我们的工作的意义不仅在于澄清不同方法之间的关系,而且还揭示了什么是一个良好的基础语义的析取逻辑程序。

英文摘要:

Much work has been done on extending the well-founded semantics to general disjunctive logic programs and various approaches have been proposed. However, these semantics are different from each other and no consensus is reached about which semantics is the most intended. In this paper we look at disjunctive well-founded reasoning from different angles. We show that there is an intuitive form of the well-founded reasoning in disjunctive logic programming which can be characterized by slightly modifying some exisitng approaches to defining disjunctive well-founded semantics, including program transformations, argumentation, unfounded sets (and resolution-like procedure). We also provide a bottom-up procedure for this semantics. The significance of our work is not only in clarifying the relationship among different approaches, but also shed some light on what is an intended well-founded semantics for disjunctive logic programs.
