In Japan, according to a survey of a company, average of meeting time per a day is 68.2 minutes. To improve the productivity of a group meeting, we need to know and measure the quality of the meeting. On the other hand, it is hard to record and analyze the conversation because of the reason of compliance. Therefore, we start considering the camera-based group meeting assessment that utilizes Omni-directional camera. We can observe various kind of facial expression and body gestures of attendees through the video. However, there is no standardized definition of human expressions. So, in this paper, we try to define the semantic human expression observed in a group meeting.
