In this paper, we present an integrated model of the two central tasks of dialog management: interpretinguseractionsand generating system actions. We model the interpretation task as a classication prob- lem and the generation task as a predic- tion problem. These two tasks are inter- leaved in an incremental parsing-based di- alog model. We compare three alterna- tive parsing methods for this dialog model using a corpus of human-human spoken dialog from a catalog ordering domain that has been annotated for dialog acts and task/subtask information. We contrast the amount of context provided by each method and its impact on performance.
