A new class of lineage expressions over probabilistic databases computable in p-time

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

We study the problem of query evaluation over tuple-independent probabilistic databases. We define a new characterization of lineage expressions called disjoint branch acyclic, and show this class to be computed in P-time. Specifically, this work extends the class of lineage expressions for which evaluation can be performed in PTIME. We achieve this extension with a novel usage of junction trees to compute the probability of these lineage expressions.
