onto2problog: A Probabilistic Ontology-Mediated Querying System using Probabilistic Logic Programming

We present onto2problog, a tool that supports ontology-mediated querying of probabilistic data via probabilistic logic programming engines. Our tool supports conjunctive queries on probabilistic data under ontologies encoded in the description logic $$\mathcal{ELH}^{dr}$$, thus capturing a large part of the OWL 2 EL profile.
