Decision Support Method in Risk Communications Using Collaborative Learning

In this paper, we propose a method for supporting risk communications that uses collaborative learning. Using collaborative learning, participants in risk communications (e.g., stakeholders, decision makers, and experts) can not only acquire desired information, but also ascertain the intentions and knowledge of other parties with different concerns. In the process of collaborative learning, the participants achieve mutual understanding of risks. Features of this method are the use of externilization and construction of a fishbone diagram of opinion understanding.
