Abstract

In a natural dialog, a considerable proportion of the utterances actually relate to the maintenance of the dialog itself rather than to furthering the task or goals motivating the conversation. For example, many utterances serve to acknowledge, clarify, correct a previous utterance rather than pursue some goal in the domain. In addition, natural dialog is full of false starts, ungrammatical sentences and other complexities not found in in written language. This paper describes our recent efforts to define and construct a model of discourse interaction that handle dialogs that are rich in these natural dialog-related phenomena.
