Query Rewriting Under Query Extensions for OWL 2 QL Ontologies

Abstract

Conjunctive query answering is a key reasoning service for many ontology-based applications. With the advent of lightweight ontology languages, such as OWL 2 QL, several query answering systems have been proposed which compute the so called UCQ rewriting of a given query.
