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.
