The Consistency Extractor System: Querying Inconsistent Databases Using Answer Set Programs

Download www.face.ubiobio.cl

Abstract. We present the Consistency Extractor System (ConsEx) that uses answer set programming to compute consistent answers to ﬁrst-order queries posed to relational databases that may be inconsistent wrt their integrity constraints. Among other features, ConsEx implements a magic sets technique to evaluate queries via disjunctive logic programs with stable model semantics that specify the repair of the original database. We describe the methodology and the system; and also present some experimental results.
