Disentangling the Lexicons of Disaster Response in Twitter
Abstract: People around the world use social media platforms such as Twitter heavily to express their opinion about various as- pects of daily life. In the same way social media changes communication in daily life, it also is transforming the way individuals communicate during disasters and emergencies. Emergency officials have come to rely on social media to communicate alerts and updates. How do users communi- cate risk on social media? We used a novel information- theoretic unsupervised learning tool, CorEx, to extract and classify highly relevant words used by the public on Twit- ter during known emergencies, such as fires, explosions, and hurricanes. By utilizing the resulting classification strategy, authorities can use the derived language to craft more rel- evant risk communication to maximize the effectiveness of short-message broadcasts such as the Wireless Emergency Alerts (WEA) service.
