Query: Controlled Query Evaluation for Datalog and OWL 2 Profile Ontologies   We study confidentiality enforcement in ontologies under the Controlled Query
Evaluation framework, where a policy specifies the sensitive information and a
censor ensures that query answers that may compromise the policy are not
returned. We focus on censors that ensure confidentiality while maximising
information access, and consider both Datalog and the OWL 2 profiles as
ontology languages.
