Our goal is to identify the features that pre- dict the occurrence and placement of dis- course cues in tutorial explanations in or- der to aid in the automatic generation of explanations. Previous attempts to devise rules for text generation were based on in- tuition or small numbers of constructed ex- amples. We apply a machine learning pro- gram, C4.5, to induce decision trees for cue occurrence and placement from a corpus of data coded for a variety of features previ- ously thought to affect cue usage. Our ex- periments enable us to identify the features with most predictive power, and show that machine learning can be used to induce de- cision trees useful for text generation.
