In this study we investigate the use of Bayesian Belief Networks (BBN) for developing a practical framework for machine learning process incorporating the commonsense reasoning. Bayesian Belief Networks grant a systematic and localized method for structuring probabilistic information about a situation into coherent whole. Bayesian networks have been established as a ubiquitous tool for modelling and reasoning under uncertainty. In this study we attempt to develop a graphical model that is used to represent knowledge about the uncertain domain in which the nodes are the random variables and the edges between the nodes represent probabilistic dependencies among the corresponding random variables. These conditional dependencies in the graph are often estimated by using some known statistical and computational methods. Thus developed Bayesian belief network along with joint probability distribution in the factored form can be used to evaluate all possible inference queries both predictive and diagnostic by marginalization. We experimentally developed a model for educational institutions which could be used to take decision on considering various factors link campus placement, total cost per year, academic excellence etc.
