In this study, we present a computational approach to support content creation by recording and reusing the conversational contents as reusable nuggets. We introduce the concept of the conversation quantization – a technique for approximating a continuous flow of conversation by a series of conversation quanta that correspond to the points in a discourse. We describe the creation of contents using conversation quanta. To realize the concept of conversation quanta, we attempt to manually extract conversation quanta from the videos of some meetings and create the conversational contents. As a result, we have confirmed that conversation quanta can be reused as conversational contents such as conversational agents and presentation contents. Further, we have obtained valuable insights into the nature of conversation quanta.
