Non-monotonic reasoning with logic programming

Non-Monotonic Reasoning with Logic Programming

Our purpose is to exhibit a modular systematic method of representing non{ monotonic reasoning problems with the Well Founded Semantics WFS of extended logic programs augmented with eXplicit negation (WFSX), augmented by its Contradiction Removal Semantics (CRSX) when needed. We apply this semantics, and its contradiction removal semantics counterpart, to represent non-monotonic reasoning probl...

Prolegomena to Logic Programming for Non-monotonic Reasoning Prolegomena to Logic Programming for Non{monotonic Reasoning

The present prolegomena consist, as all indeed do, in a critical discussion serving to introduce and interpret the extended works that follow in this book. As a result, the book is not a mere collection of excellent papers in their own specialty, but provides also the basics of the motivation, background history, important themes, bridges to other areas, and a common technical platform of the p...

Logic Programming for Non-Monotonic Reasoning

Our purpose is to exhibit a modular systematic method of representing nonmonotonic reasoning problems with the Well Founded Semantics of extended logic programs aumented with eXplicit negation (WFSX), augmented by its Contradiction Removal Semantics (CRSX) when needed. We show how to cast in the language of such logic programs forms of non-monotonic reasoning like defeasible reasoning and hypot...

A Unifying View for Logic Programming with Non-Monotonic Reasoning

We provide a simple formulation of a framework where some extensions of logic programming with non-monotonic reasoning are treated uniformly, namely two kinds of negation and abduction. The resulting semantics is purely model-theoretic, and gives meaning to any non-contradictory abductive logic program. Moreover, it embeds and generalizes some existing semantics which deal with negation and abd...
