Response generation should also be beneficial in building "chatterbots" (Weizenbaum, 1966) for entertainment purposes or companionship (Wilks, 2006).
we are most excited by the future potential of data-driven response generation when used inside larger dialogue systems, where direct consideration of the user's utterance could be combined with dialogue state (Wong and Mooney, 2007;Langner et al., 2010) to generate locally coherent, purposeful dialogue.
