On Axiomatizing Probabilistic Conditional Independencies in Bayesian Networks

Several researchers have suggested that Bayesian networks (BNs) should be used to manage the inherent uncertainty in information retrieval. However, it has been argued that manually constructing a large BN is a difficult process. In this paper, we obtain the only minimal complete subset of the semi-graphoid axiomatization governing the independency information in a BN. This result may be useful in developing an automated BN construction procedure for information retrieval purposes.
