Properties of Bel currents

The Bel tensor is divergence-free in some important cases leading to the existence of conserved currents associated to Killing vectors analogously to those of the energy-momentum tensor. When the divergence of the Bel tensor does not vanish one can study the interchange of some quantities between the gravitational and other fields obtaining mixed total conserved currents. Nevertheless, the Bel ...

Silver Bullet Talks with Christofer Hoff

Christofer Hoff: Well, there’s fog and then there’s my favorite analogy of the “goat rodeo,” but I think they’re both relatively accurate. It’s very interesting that this question comes up so many times, and I’ve rehearsed the answer depending on the audience. What I’ve kind of arrived at is that there are two very interesting perspectives to take when answering that question: one from the prov...

BEL: Bagging for Entity Linking

With recent advances in the areas of knowledge engineering and information extraction, the task of linking textual mentions of named entities to corresponding ones in a knowledge base has received much attention. The rich, structured information in state-of-the-art knowledge bases can be leveraged to facilitate this task. Although recent approaches achieve satisfactory accuracy results, they ty...

The Bayesian Description Logic BEL

We introduce the probabilistic Description Logic BEL. In BEL, axioms are required to hold only in an associated context. The probabilistic component of the logic is given by a Bayesian network that describes the joint probability distribution of the contexts. We study the main reasoning problems in this logic; in particular, we (i) prove that deciding positive and almost-sure entailments is not...
