We study the formal relationships between the inferential aspects of Carneades (a general argumentation framework) and Defeasible Logic. The outcome of the investigation is that t...
We define the semantics of logic programs with (abstract) constraint atoms in a way closely tied to default logic. Like default logic, formulas in rules are evaluated using the cl...
Much work has been done on extending the well-founded semantics to general disjunctive logic programs and various approaches have been proposed. However, no consensus has been reac...
World-set algebra is a variable-free query language for uncertain databases. It constitutes the core of the query language implemented in MayBMS, an uncertain database system. Thi...
In this work we recall the first steps towards the definition of an answer set semantics for residuated logic programs with negation, and concentrate on the development of relati...
