Input: The semigraphoid closure of every couple of CI-statements (CI=conditional indepen­ dence) is a stochastic CI-model. As a con­ sequence of this result it is shown that ev­ ery probabilistically sound inference rule for CI-models, having at most two antecedents, is derivable from the semigraphoid inference rules. This justifies the use of semigraphoids as approximations of stochastic CI-models in probabilistic reasoning. The list of all 19 po­ tential dominant elements of the mentioned semigraphoid closure is given as a byproduct.

Semigraphoids are Two-Antecedental Approximations of Stochastic Conditional Independence Models
