LISA(ID:2172/lis002)

LISP expert system shell 

• LISA Home Page 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). 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. LISA can reason over CLOS objects without imposing special class hierarchy requirements; thus it should be possible to easily augment existing CLOS applications with reasoning capabilities. Also, the full power of Common Lisp is available for use within productions; there is no dichotomy between the programming language and its implementation. The project's goals include complete freedom of availability, ease of portbility, simplicity (so that new developers can easily understand code layout and behavior), familiarity (LISA has its roots in CLIPS and JESS, so it will be familiar to those who've worked with these systems), and flexibility.
