An Overview of Public Concerns During the Recovery Period after a Major Earthquake: Nepal Twitter Analysis

摘要

In responding to disasters, Twitter is extensively used, both for information exchange and mapping the crisis, among citizens, and in relation to national and international humanitarian responders. This paper reports Twitter analysis aimed at identifying the most pressing issues that arose in the short term recovery phase starting about a week after the Nepal earthquake, including the heretofore neglected topic of mismatch between international relief and local cultures. Based on Twitter data collected between April 30th and May 6th 2015. 1,074,864 raw messages apparently related to the Nepal earthquake were retrieved, filtered and analyzed. This exploratory adapts established frameworks for use in the dataset. The results show that our framework can identify several unique problems, including that disaster relief efforts can trigger negative sentiments when they are conducted without understanding of the local cultures.
