"As one of the popular and important probabilistic graphical models, Bayesian network (BN) is the effective framework for representing and inferring uncertain knowledge by means of qualitative and quantitative manners. In this book, adopting BN as the framework of knowledge representation and inferences, we consider the following issues: Learning BN from massive data using MapReduce; Inferences of large-scale BN using MapReduce; BN-based lineage representation and analysis over uncertain data; Lineage-driven and BN-based error detection in uncertain data; Fusion of uncertain knowledge in dynamic data."--Preface
