Reformulation of Global Constraints in Answer Set Programming
We show that global constraints on finite domains like alldifferent can be reformulated into answer set programs on which we achieve arc, bound or range consistency. These reform...

Answer Sets for Consistent Query Answering in Inconsistent Databases
A relational database is inconsistent if it does not satisfy a given set of integrity constraints. Nevertheless, it is likely that most of the data in it is consistent with the co...
