EnglishWe provide a simple formulation of a framework where three main extensions of logic programming for non-monotonic reasoning are treated uniformly: Negation-by-default, explicit negation and abduction. The resulting semantics is purely model-theoretic and gives meaning to any consistent abductive logic program. Moreover, it embeds and generalises existing semantics which deal with negation and abduction separately. The abductive framework is equipped with a correct top-down proof procedure.

| Abstract: | We provide a simple formulation of a framework where three main extensions of logic programming for non-monotonic reasoning are treated uniformly: Negation-by-default, explicit negation and abduction. The resulting semantics is purely model-theoretic and gives meaning to any consistent abductive logic program. Moreover, it embeds and generalises existing semantics which deal with negation and abduction separately. The abductive framework is equipped with a correct top-down proof procedure. |
