Abstract
The present invention automatically builds question sets for a decision tree. Under the invention, mutual information is used to cluster tokens, representing either phones or letters. Each cluster is formed so as to limit the loss in mutual information in a set of training data caused by the formation of the cluster. The resulting sets of clusters represent questions that can be used at the nodes of the decision tree.
