扩充析取逻辑程序的争论语义

摘要

该文探讨争论推理在扩充逻辑程序中的实现及其关系问题.基于"相干原理",建立了扩充逻辑程序的争论推理框架,多种争论推理形式都可以嵌入其中.特别是提出了一种谨慎语义Acc.同时又定义了良基语义的一种合理扩充Mod,以处理较为大胆的推理形式.另外也研究了相关的理论性质.%An investigation into the relationship between argumentation and disjunctive logic programs with explicit negation (EDLP) is conducted.By employing the coherence principle,an argumentation-theoretic framework for EDLP is presented,in which various forms of argumentation can be performed.In particular,a skeptical semantics Acc is introduced in a natural way.To provide a more suitable form of argumentation,a less skeptical semantics Mod is also defined which naturally extends the well-founded model.
