Logic Programming '88: Proceedings of the 7th Conference, Tokyo, Japan, April 11-14, 1988 (Lecture Notes in Computer Science / Lecture Notes in Artific)

"This volume contains a selection of papers presented at the Seventh Logic Programming Conference that took place in Tokyo, April 11-14, 1988. It is the successor to the previous conference proceedings published as Lecture Notes in Computer Science Volumes 221, 264 and 315. The book covers various aspects of logic programming such as foundations, programming languages/systems, concurrent programming, knowledge bases, applications of computer-aided reasoning and natural language processing. The papers on foundations present theoretical results on "narrowing", a proof strategy for proving properties of Prolog programs based on inductionless induction and several issues in nonmonotonic reasoning. Of special interest to mathematicians is the paper on computer-aided reasoning, which describes a system for assisting human reasoning. Natural language application papers treat the lexical analysis of Japanese sentences, a system that generates a summary of a given sentence and a new knowledge representation formalism suited for representing dynamic behavior by extending the frame system."--Publisher's website Completeness of extended unification based on basic narrowing....Pages 1-10 Proving definite clauses without explicit use of inductions....Pages 11-26 Pseudo extension in default reasoning and belief revision by model inference....Pages 27-37 An approach to nonmonotonic inference mechanism in production system KORE/IE....Pages 38-52 Nonmonotonic parallel inheritance network....Pages 53-66 Logic programming debugger using control flow specification....Pages 67-81 ALEX: The logic programming language with explicit control and without cut-operators....Pages 82-95 Lattice programming methodology....Pages 96-107 A simple programming system written in GHC and its reflective operations....Pages 108-121 Implementation of full GHC by communicating processes....Pages 122-135 Inference methods and semantics on or-type knowledge bases....Pages 136-155 Access program to minimize redundant refutations on the network database system....Pages 156-171 EUODHILOS: A general-purpose reasoning assistant system — Concept and implementation —....Pages 172-187 Logic based lexical analyser LAX....Pages 188-216 Extraction of characteristic facts and abstract generation....Pages 217-237 Knowledge representation and reasoning for discourse understanding....Pages 238-251 "This volume contains selected papers presented at the Eighth Logic Programming Conference, held in Tokyo, 1989. Various topics in logic programming are covered. The first paper is an invited talk by Prof. Donald Michie, Chief Scientist of the Turing Institute, entitled "Human and Machine Learning of Descriptive Concepts", and introduces various research results on learning obtained by his group. There are eleven further papers, organized into sections on reasoning, logic programming language, concurrent programming, knowledge programming, natural language processing, and applications. A paper on knowledge programming introduces a flexible and powerful tool for incorporating and organizing knowledge using hypermedia. Another paper presents the constraint logic programming language cu-Prolog, designed for combinatorial problems; the way cu-Prolog solves the constraints is based on program transformation."--Publisher's Website.
