| 摘 要： | 人工智能以知识为基础,然而知识往往是可错的.当知识被发现是错误时,就要撤销该错误知识及依赖于该错误知识的知识.基于对Forget机制、TMS和ATMS的改进,提出一种新的知识表示方法,即带有依赖关系的知识库.基于命题逻辑程序,给出带有依赖关系的知识库的示例,同时还给出1个规则加入算法和2个规则撤销算法.第2个规则撤销算法可以处理循环依赖关系.带有依赖关系的知识库,是一种全新结构的知识库,在知识表示、信念修正和辩论推理中具有应用的前景.

| Abstract: | Knowledge plays an important role in artificial intelligence,but there is the possibility that knowledge turns out to be erroneous.When a proposition turns out to be erroneous,this erroneous proposition and the other propositions,which depend on the erroneous proposition,will be retracted from the knowledge base.Based on TMS and ATMS,this paper presents a novel representation of knowledge,i.e.knowledge base with dependencies.This paper applies this idea to propositional logic program.Given a logic program,c... |
