摘要:

我们研究概率信息(弱)版本的传递性,通过使用合适的定义的默认值和否定的默认值,在设置的连贯性和不精确的概率。我们表示p-一致的序列的默认值和/或否定的默认值的g-相干的不精确概率评估的相应序列的条件事件。最后,我们证明了弱传递性的连贯概率传播规则和有效性的选择推理模式,通过证明相关的知识库的p-蕴涵。

英文摘要:

We study probabilistically informative (weak) versions of transitivity, by using suitable definitions of defaults and negated defaults, in the setting of coherence and imprecise probabilities. We represent p-consistent sequences of defaults and/or negated defaults by g-coherent imprecise probability assessments on the respective sequences of conditional events. Finally, we prove the coherent probability propagation rules for Weak Transitivity and the validity of selected inference patterns by proving the p-entailment for the associated knowledge bases.
