Chat systems are being used to activate discussion at conferences. In general, it is desirable that many questions are sent to chat systems. However, if no one may answer the question, one will hesitate to make a question. In this study, we assume that users will send more questions if the questions always receive some sort of response. We propose a chat system that uses a question answering system (QA system) as a bot that always responds to questions. This chat system is not a general chat system but a system dedicated to questions and their answers. We actually created the proposed system and used it in our laboratory meeting to verify the functionality and its design. As the result, we have verified that all the questions are actually answered by the QA system.
