CLIPS - a powerful development and delivery expert system tool

Abstract Much of the attention in large expert systems has been on LISP based systems. Several problems that are inherent in LISP based systems include: limited availability of LISP machines and LISP languages on conventional computers; low portability; and restricted capability for integration with other languages, particularly data base systems. To facilitate the delivery of expert systems, the Artificial Intelligence Section of the Mission Planning and Analysis Division at NASA/Johnson Space Center has developed an expert system tool called CLIPS which provides high portability and ease of integration with most external computer languages.
