Estimation of Novelty Assessment of Strategic Scenarios Using Relativeness

A scenario is the series of elements of information which supports decision making. Action Planning is a method for cultivating ideas to generate practical scenarios of actions (strategic scenarios). Frameworks and items on Action Planning sheets provide participants with constraint, and guide creative thinking to solve social issues. In this study, we propose a method for evaluating a value of a strategic scenario. We define novelty as one of the indicators to assess strategic scenarios, and introduce the concept of Relativeness to calculate the closeness between a role and knowledge included in strategic scenarios. A role is an attribute of a participant which is a job selected from real world. By regarding a word as the smallest unit of knowledge in strategic scenarios, Relativeness takes the function of an indicator to measure the degree of affinities between a role and a scenario. The result of our experiment suggests that combining low relative knowledge with roles may lead to a high assessment of novelty in strategic scenarios, and Relativeness may work as the automatic method for estimating subjective assessment.
