Abstract
This paper presents an extension of the Rhetorical Structure Theory (RST) from modeling monologues to two-party dialogues. We show how RST can be suitably applied to build an initial synoptic model of the exchange structure and then how rhetorical relations can be especially useful in modeling various types of interruptions that may dynamically occur in an exchange. Our dialogue model and theory are finally illustrated through selected examples from cooperative tutorial dialogues. The result of our work is the construction of a dynamic model of exchange, grounded on the idea of RST, that can handle interruptions to an arbitrary level of nesting in a coherent manner. We contend that our dynamic process model provides a different approach of modeling cooperative and negotiative-type of dialogues than previous models; controls when the completion of the exchange has been reached; facilitates natural passing to the next exchange after the current one is completed; allows smooth resumption of its interruption; and most importantly accounts for the global coherence of the dialogue by knowing the role and function that each (statis or interrupting) move plays in the dialogue at any point.
