  abstract  = {In dialogue systems, conveying understanding results of user utterances is
	important because it enables users to feel understood by the system. However,
	it is not clear what types of understanding results should be conveyed to
	users; some utterances may be offensive and some may be too commonsensical. In
	this paper, we explored the effect of conveying understanding results of user
	utterances in a chat-oriented dialogue system by an experiment using human
	subjects. As a result, we found that only certain types of understanding
	results, such as those related to a user's permanent state, are effective to
	improve user satisfaction. This paper clarifies the types of understanding
	results that can be safely uttered by a system.},
