The semantics of class-based languages can be defined in terms of objects only [8, 7, 1] if classes are viewed as objects with a constructor method. One obtains a store in which m...
The stable semantics has become a prime candidate for knowledge representation and reasoning. The rules associated with propositional logic programs and the stable semantics are no...
As no plan can cover all possible contingencies, the ability to detect failures during plan execution is crucial to the robustness of any autonomous system operating in a dynamic ...
The Semantic Web initiative defines important challenges for knowledge representation and database systems. Recently, several standards for representation languages have been pro...
Disjunctive Logic Programming (DLP) is a very expressive formalism: it allows to express every property of finite structures that is decidable in the complexity class ¡£¢¤ (...
