Bulletin Board System for Scenario Creation based on a Sub-Story Model

It is important to decide the next action for a collaborative community. The leader of a collaborative community must choose an action that increases rewards and reduces risks. When a leader cannot make this decision, the action will be determined through community member discussion. However, this decision cannot be made in blind discussions, so systematic discussion is necessary for choosing effective actions in limited time. In addition, the repetition of divergence and convergence in the discussion according to the members’ common knowledge and backgrounds will lead to an effective conclusion. In this paper, we propose a bulletin board system framework in which the scenario creation, a series of actions to be undertaken, is established through the discussion and exchange of opinions.
