We describe the Consistency Extractor System (ConsEx) that computes consistent answers to Datalog queries with negation posed to relational databases that may be inconsistent with...
This paper discusses the background, algorithms and implementation techniques to support programmers in ‘debugging’ logic programs under the answer set semantics. We first inv...
In a recent paper, Ferraris, Lee and Lifschitz conjectured that the concept of a stable model of a first-order formula can be used to treat some answer set programming expressions...
