Abstract
This paper proposes a methodology to understand the contents discussed after disasters in the macro debate domain such as articles in newspapers, in order to evaluate the legitimacy of decision making in disaster emergency policies. The concept of ontology is utilized to formulate the structure of observed corpus. By conceptualizing the contents of newspaper articles as a part of macro debate, issues which should be concerned at decision making process after disasters are summarized. This methodology may contribute to the evaluation of decision making process of previous disasters and the proposal of effective emergency disaster policies for possible future disasters.
