Abstract(in English) A document called a chronology log which records events on a time scale is recorded in the disaster management headquarters. Each event is recorded with the content of a message, the time, the sender and the recipient in chronological order. The documents are created for recording the activity of prefectural office and medical headquarter, thus it could contribute to management of disaster medical care system to establish a method to analyze chronology logs with natural language processing. As the first step in this direction, this paper reports the experimental results of the classification of chronological reports with document clustering models. We will discuss further improvement of the accuracy of the classification.
