Acyclicity notions for existential rules and their application to query answering in ontologies

Acyclicity notions for existential rules and their application to query answering in ontologies

Answering conjunctive queries (CQs) over a set of facts extended with existential rules is a prominent problem in knowledge representation and databases. This problem can be solved using the chase algorithm, which extends the given set of facts with fresh facts in order to satisfy the rules. If the...
