Many CLIPS rule-bases contain one or more rule groups that perform
classification.  In this paper we describe CLIPS-Induce, an automated
system for the creation of a CLIPS classification rule-base from a set
of test cases.  CLIPS-Induce consists of two components, a decision tree 
induction component and a CLIPS production extraction component.  ID3 
(Quinlan, 1986), a popular decision tree induction algorithm, is 
used to induce a decision tree from the test cases.  CLIPS production 
extraction is accomplished through a top-down traversal of the decision 
tree.  Nodes of the tree are used to construct query rules, and branches 
of the tree are used to construct classification rules.  The learned 
CLIPS productions may easily be incorporated into a large CLIPS system that
perform tasks such as accessing a database or displaying information.
