Abstract
In Japan, social interests on natural disaster are so strong that the public have high expectations of promotion of research on disaster prevention. However, because it is hard for academics to know social interests, academics have difficulty planning research strategy for disaster prevention based on evidence of social needs. The fundamental cause of this difficulty is arising from lack of method for quantification of academic / social interests. Otherwise, text analysis approach which have been greatly improved in recent years makes it possible to quantify someone's interests which are vague and elusive. In addition, it is now easier than ever to get enough text data. In this research, we suggest text analytic approach to quantify academic / social interests and proximity of academic and social interests in disaster prevention.
