Approximating Answer Sets of Unitary Lifschitz-Woo Programs
We investigate techniques for approximating answer sets of general logic programs of Lifschitz and Woo, whose rules have single literals as heads. We propose three different method...

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...

Towards a Fuzzy Answer Set Semantics for Residuated Logic Programs
In this work we introduce the first steps towards the definition of an answer set semantics for residuated logic programs with negation.

A New Algorithm for Answer Set Computation
A new exact algorithm for computing answer sets of logic programs is presented and analyzed. The algorithm takes a logic program in Kernel normal form as an input and computes its ...
