Task-Oriented Tutorial Dialogue: Issues and Agents
Jeff Rickel, Rajaram Ganeshan, Charles Rich, Candace L. Sidner, Neal B. Lesh · 2000
Towards our goal of developing computer tutors that can collaborate with students on tasks in simulated environments, we have built a series of four prototype tutors. These tutors integrate two independent but related strands of research: intelligent tutoring systems and task-oriented dialogue systems. While the tutors share a core approach to teaching procedural tasks, eachwas designed to explore a different set of issues. This paper outlines the issues that arise in task-oriented tutorial dialogue and the ways they have been addressed in these four tutors.
