On Natural Language Based Computer Systems

Abstract

Some of the arguments that have been given both for and against the use of natural languages in question-answering and programming systems are discussed. Several natural language based computer systems are considered in assessing the current level of system development. Finally, certain pervasive difficulties that have arisen in developing natural language based systems are identified, and the approach taken to overcome them in the REQUEST (Restricted English QUESTion-Answering) System is described.
