Complexity of approximate query answering under inconsistency in datalog+/-

Complexity of approximate query answering under inconsistency in datalog+/-

Show other versions (1)

Several semantics have been proposed to query inconsistent ontological knowledge bases, including the intersection of repairs and the intersection of closed repairs as two approximate inconsistency-tolerant semantics. In this paper, we analyze the complexity of conjunctive query answering under thes...
