Complexity aspects of various semantics for disjunctive databases

Published: 01 August 1993 Publication History

Abstract

This paper addresses complexity issues for important problems arising with disjunctive databases. In particular, the complexity of inference of a literal and a formula from a propositional disjunctive database under a variety of well-known disjunctive database semantics is investigated, as well deciding whether a disjunctive database has a model under a particular semantics. The problems are located in appropriate slots of the polynomial hierarchy.
