Anytime approximation in probabilistic databases
<15>
This article describes an approximation algorithm for computing the probability of propositional formulas over discrete random variables. It is used by the SPROUT query engine to approximate the probabilities of results to relational algebra queries on expressive probabilistic databases. It puts together research previously reported in International Conferences on Database Theory (ICDT 2011) and on Data Engineering (ICDE 2010 and 2011). Aspects of this work were used and extended for top-k by Olteanu (ICDE 2012) and Theobald (ICDE 2013), for aggregates by Fink (VLDB 2012), for XML by Senellart (ICDE 2013), for explanation and sensitivity analysis by Deshpande (SIGMOD 2011).
