– Titre : Decidable Fragments of Horn First-Order Logic
 – Sommaire : In this seminar, we present recent results about Existential Rules, an undecidable Horn fragment of first-order logic that is widely used in ontological modelling. Namely, we discuss the main approaches devised to retrieve decidability as well as efficient implementations to solve complex reasoning tasks.
