Establishing shared knowledge is indispensable to construct a safe and secure society. With the goal of providing information technologies helping knowledge sharing in a society, this paper proposes a conversational agent that can produce a presentation with natural nonverbal expressions, such as gestures and facial expressions. We also describe an information providing system into which the conversational agent is integrated. First, analyzing human presentation video-data, we establish a model of human gesture usage. Then, we implement the model into a conversational agent who works as a presenter. Finally, we will discuss the effectiveness of such systems in terms of information sharing in a society.
