Lineage-Aware Temporal Windows: Supporting Set Operations in Temporal-Probabilistic Databases
Katerina Papaioannou, Martin Theobald, Michael H. Böhlen
In temporal-probabilistic (TP) databases, the combination of the temporal and the probabilistic dimension adds significant overhead to the computation of set operations. Although s…
Generalized Lineage-Aware Temporal Windows: Supporting Outer and Anti Joins in Temporal-Probabilistic Databases
Katerina Papaioannou, Martin Theobald, Michael Böhlen
The result of a temporal-probabilistic (TP) join with negation includes, at each time point, the probability with which a tuple of a positive relation matches none of the…
A General Framework for Anytime Approximation in Probabilistic Databases
Maarten Van den Heuvel, Floris Geerts, Wolfgang Gatterbauer +1
Anytime approximation algorithms that compute the probabilities of queries over probabilistic databases can be of great use to statistical learning tasks. Those approaches have bee…
