英文摘要 | The paper presents a general framework for PROSPECTOR-type uncertain reasoning schemes. On the basis of the framework, different PROSPECTOR-type measures of rule-uncertainty are defined to capture different semantics or to differ so-called credulous experts from so-called skeptical experts. For the each of these new measures, the formulas for the corresponding conditional probabilitied from its parameters are given in order that the propagation for the uncertainties through an inference network depends only on that for the corresponding probabilities, the constraint relationships between its two parameters are described, which human experts have follow on supplying the values for them, and the formula for the prior probability of the antecedent part of a rule is proposed, which referred by the sequential propagation formulae. Also, the relational equations between them and the relational equations between them and MYCIN certainty factors are given. |
