摘要 人们分析了MYcIN确定因子的定义川之后,发现了它的一些缺点,并给出了如下一些新定义: This paper presents a general probability-based framework for MYCIN-like Certainty Factors approach. On the basis of the framework, four kinds of new MYCIN-like Certainty Fac-tors are defined and discussed. One of them,called Odds Certainty Factor,has the semantics similar to MYCIN's,but the propagation of its estimate for the same uncertainty is different from that of MYCIN's. Perhaps can be used to distinguish between so-called credulous experts and so-called skeptical experts.
