CLIPS is an acronym for C Language Integrated Production System.

It is a rules-based programming framework designed for building expert systems. Its programming language COOL is similar to LISP and allows object-oriented as well as procedural programming. CLIPS itself is written in C and can be embedded in programs of other languages.

CLIPS core is a forward-chaining inference engine based on the Rete algorithm designed by Dr. Charles L. Forgy of Carnegie Mellon University.

It was developed starting 1985 at NASA to replace the existing LISP based expert system building tool ART*Inference and released into the public domain in the 1990s.

The original name of CLIPS was NASA's AI Language(NAIL).
