At the Dialogue Robot Competition 2023 (DRC2023), which was held to improve
the capability of dialogue robots, our team developed a system that could build
common ground and take more natural turns based on user utterance texts. Our
system generated queries for sightseeing spot searches using the common ground
and engaged in dialogue while waiting for user comprehension.
