A decision-tree-based symbolic rule induction system for text categorization

by D. E. Johnson, F. J. Oles, T. Zhang, T. Goetz
We present a decision-tree-based symbolic rule induction system for categorizing text documents automatically. Our method for rule induction involves the novel combination of (1) a fast decision tree induction algorithm especially suited to text data and (2) a new method for converting a decision tree to a rule set that is simplified, but still logically equivalent to, the original tree. We report experimental results on the use of this system on some practical problems.
