Probabilistic Data Formalisms Real-world applications model probabilistic data using a plethora of different formalisms, Bayesian networks are a natural fit for managing expert knowledge, where the probabilistic relationship between input random variables, which are observable quantities, unknown parameters, or hypotheses, exhibits conditional independence.(More)
Πgora is an integration system for probabilistic data modelled using different formalisms such as pc-tables, Bayesian networks, and stochastic automata. User queries are expressed over a global relational layer and are evaluated by Πgora using a range of strategies, including data conversion into one probabilistic formalism followed by(More)
