Michel Leclère, Marie-Laure Mugnier, Guillaume Pérution-Kihli
We consider the issue of answering unions of conjunctive queries (UCQs) with disjunctive existential rules and mappings. While this issue has already been well studied from a chase…
Worst-case Optimal Query Answering for Greedy Sets of Existential Rules and Their Subclasses
Sebastian Rudolph, Michaël Thomazo, Jean-François Baget +1
The need for an ontological layer on top of data, associated with advanced reasoning mechanisms able to exploit the semantics encoded in ontologies, has been acknowledged both in t…
Extending Acyclicity Notions for Existential Rules (\emph{long version})
Jean-Francois Baget, Fabien Garreau, Marie-Laure Mugnier +1
Existential rules have been proposed for representing ontological knowledge, specifically in the context of Ontology-Based Query Answering. Entailment with existential rules is und…
Revisiting Chase Termination for Existential Rules and their Extension to Nonmonotonic Negation
Jean-François Baget, Fabien Garreau, Marie-Laure Mugnier +1
Existential rules have been proposed for representing ontological knowledge, specifically in the context of Ontology- Based Data Access. Entailment with existential rules is undeci…
