I am a Ph.D. student at Augmented Human Communication Lab (AHC), Nara Institute of Science and Technology (NAIST). Since I was an undergraduate student, I have been strongly interested in systems that interact with users. During my undergraduate, I made some products to pursue my interest. I have been studying dialogue systems in my graduate school. My current research interest is thoughtful dialogue agents that respond with thoughtful actions to ambiguous user requests. The agents assume to be used in tasks that users sometimes can not clearly verbalize their requests such as sightseeing navigation or hotel reception. I also interested in how dialogue systems use external knowledge such as event causality. I have been studying these topics to develop a dialogue agent that can support users in diverse situations as well as thoughtful human concierges.
