## About these proceedings

### Introduction

This book contains papers which investigate how to extend
logic programming toward the artificial intelligence and
software engineering areas, covering both theoretical and
practical aspects. Some papers investigate topics such as
abductive reasoning and negation. Some works discuss how to
enhance the expressive power of logic programming by
introducing constraints, sets, and integration with
functional programming. Other papers deal with the
structuring of knowledge into modules, taxonomies, and
objects, withthe aim of extending logic programming toward
software engineering applications. A section is devoted to
papers concentrating on proof theory and inspired by
Gentzen-style sequent or natural deduction systems. Topics
such as concurrency are considered to enhance the expressive
power of logic languages. Finally, some papers mainly
concernimplementation techniques for some of these logic
programming extensions.
