What to Expect When the Unexpected Happens: Social Media Communications Across CrisesProceedings of CSCW 2015 (2015)
AbstractThe use of social media to communicate timely information during crisis situations has become a common practice in re- cent years. In particular, the one-to-many nature of Twitter has created an opportunity for stakeholders to disseminate crisis-relevant messages, and to access vast amounts of in- formation they may not otherwise have. Our goal is to under- stand what affected populations, response agencies and other stakeholders can expect—and not expect—from this data in various types of disaster situations. Anecdotal evidence sug- gests that different types of crises elicit different reactions from Twitter users, but we have yet to see whether this is in fact the case. In this paper, we investigate several crises including natural hazards and human-induced disasters, in a systematic manner and with a consistent methodology. This leads to insights about the prevalence of different information types and sources across a variety of crisis situations.
