Usage of discourse markers in tutorial language can make the difference between stilted and natural sounding dialogue. In this paper we describe some simple rules for selection of discourse markers. These rules were derived for use in an intelligent tutoring system by applying decision-tree machine learning to human tutoring language. The fact that these(More)
CIRCSIM-Tutor is a dialogue-based intelligent tutoring system that conducts dialogues with medical students about blood pressure regulation. To obtain models for computer-generated dialogues, we analyzed dialogues involving expert human tutors. In this paper we describe some of the interesting and complex patterns we isolated from the human tutorial(More)
We are investigating computer-assisted methods for identifying plan operators at both the conversational strategy and surface generation levels. We are using standard-conforming SGML markup on our corpus in order to be able to process it mechanically. We are using C4.5 to identify rules of the form "when is goal x implemented with plan y?". We are currently(More)
An intelligent tutoring system, CIRCSIM-Tutor tutors first-year medical students on blood pressure regulation based on the dialogue patterns of human tutors. To obtain data about the language and conversation patterns of human tutors, we analyzed transcripts of human tutors working over a modem, then annotated them to show tutorial goal structure. In this(More)
