# PEARL - A Package for Efficient Access to Representations in LISP

Michael Deering, Joseph Faletti, Robert Wilensky

*Proceedings of the Seventh International Joint Conference on Artificial Intelligence*, pages 930-931.

## Abstract

PEARL is an AI language developed with space and lime etJiciencies in mind . In addition to providing the usual facilities such as slot-tiller objects, demons and associat ive data bases, PEARL introduces stronger typing on slots, user-assisted hashing mechanisms, and a forest of data bases . The resulting product is a simple, but powerful and efficient tool for AI research .
