  Latent truth discovery, LTD for short, refers to the problem of aggregating
ltiple claims from various sources in order to estimate the plausibility of
atements about entities. In the absence of a ground truth, this problem is
highly challenging, when some sources provide conflicting claims and others no
claims at all. In this work we provide an unsupervised stochastic inference
procedure on top of a model that combines restricted Boltzmann machines with
feed-forward neural networks to accurately infer the reliability of sources as
well as the plausibility of statements about entities. In comparison to prior
work our approach stands out (1) by allowing the incorporation of arbitrary
features about sources and claims, (2) by generalizing from reliability per
source towards a reliability function, and thus (3) enabling the estimation of
source reliability even for sources that have provided no or very few claims,
(4) by building on efficient and scalable stochastic inference algorithms, and
(5) by outperforming the state-of-the-art by a considerable margin.
