Probability-Based MYCIN- like Certatinty Factor Models
基于概率的类MYCIN确定因子模型

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.
