Abstract(in English) | Using tweets extracted from Twitter during the Great East Japan Earthquake 2011, social network analysis techniques were used to generate and analysis the online networks that emerged at that time. People attempted to collect information about earthquakes and to communicate with friends through the twitter, and it is coping with the earthquake disaster. The aim was to identify active players for the Great East Earthquake on twitter. We construct a communication network and calculate two centrality measures(degree and betweenness) on twitter. As a result, Important players during the Great East Japan Earthquake were found to be: media reporters, people from not-for-profit, social media volunteers, newspaper publishing company, celebrity, and autonomous computer program. |
