Abstract

In spite of the fact that BN is inherently capable of representing, learning, and reasoning with uncertain knowledge , the performance of BN highly depends on the size of available training dataset. A proper learning of the network needs large amount of observed data be available during the training procedure. Otherwise, it may result in strongly biased inference due to parameter learning uncertainty . The recent research indicates that a prior knowledge about the respective domain  may help in reducing such epistemic uncertainty . This chapter discusses on semBnet, a semantically enhanced Bayesian network model, which has inherent capability of incorporating external knowledge over the associated domain. Consequently, semBnet is potential enough to model spatio-temporal relationships  in an improved manner with incorporated domain knowledge . The performance of semBnet-based prediction model has been evaluated in comparison with a number of conventional statistical and state-of-the-art space-time prediction models, with respect to a case study on climatological time series data . Experimental result demonstrates the superiority of semBnet over the other models considered.
