Turn Planning in CIRCSIM-Tutor
Feng-Jen Yang, Jung Hee Kim, Michael Glass, Martha W. Evens · 2000
Turn planning is not well-studied in natural language dialogue systems. The current version of CIRCSIM-Tutor attempts to imitate human tutorial dialogue. It generates comprehensible conversation but sounds unnatural. We propose to add a turn planner to improve intra-tum coherence by overall planning of variable references, discourse markers, acknowledgments and softeners. This paper specifies the architecture of the turn planner, which we believe will improve the rhetorical structure in the CIRCSIM-Tutor d main to a reasonable level. Since the idea is not domain dependent, it is potentially applicable to most natural language dialogue systems, especially Socratic dialogue systems.
