Knowledge–based Reference Resolution for Dialogue Management in a Home Domain Environment

Several features of spoken dialogue systems require advanced reference resolution strategies. This paper presents a knowledge–based strategy for reference resolution implemented over an agent architecture which differentiates the Knowledge and Action Managers from the Dialogue Manager. The strategy, in conjunction with the ability of the Dialogue Manager to manipulate the dialogue history, has been applied to a home environment domain to solve successfully different phenomena such as quantification, anaphoric expressions and coordination.
