Lisp-based Intelligent Software Agents
Encyclopedia
The Lisa project is a platform for the development of Lisp-based Intelligent Software Agents. Lisa is a production-rule system implemented in the Common Lisp Object System (CLOS), and is heavily influenced by CLIPS
and the Java
Expert System Shell (JESS).
At its core is a reasoning engine based on an object-oriented implementation of the Rete algorithm
, a very efficient mechanism for solving the difficult many-to-many matching problem.
Intrinsic to Lisa is the ability to reason over CLOS objects without imposing special class hierarchy requirements; thus it should be possible to easily augment existing CLOS applications with reasoning capabilities. As Lisa is an extension to Common Lisp
, the full power of the Lisp environment is always available. Lisa-enabled applications should run on any ANSI-compliant Common Lisp platform.
CLIPS
CLIPS is a public domain software tool for building expert systems. The name is an acronym for "C Language Integrated Production System." The syntax and name was inspired by Charles Forgy's OPS...

Java (programming language)
Java is a programming language originally developed by James Gosling at Sun Microsystems and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities...

Rete algorithm
The Rete algorithm is an efficient pattern matching algorithm for implementing production rule systems. The Rete algorithm was designed by Dr Charles L. Forgy of Carnegie Mellon University, first published in a working paper in 1974, and later elaborated in his 1979 Ph.D. thesis and a 1982 paper...

Common Lisp
Common Lisp, commonly abbreviated CL, is a dialect of the Lisp programming language, published in ANSI standard document ANSI INCITS 226-1994 , . From the ANSI Common Lisp standard the Common Lisp HyperSpec has been derived for use with web browsers...
