New Age of Crisis Management with Social Media

Abstract

Social Media (SM) Volunteered Geographic Information (VGI) is gradually being used for representing the real-time situation during emergency. This chapter presents the SM-VGI review as a new age contribution to emergency management. The study analyses a series of emergencies during the so-called coup attempt within the boundary of Istanbul on the 15th of July 2016 in terms of spatial clusters in time and textual frequencies within 24 h. The aim of the study is to gain an understanding of the usefulness of geo-referenced Social Media Data (SMD) in monitoring emergencies. Inferences exhibit that SM-VGI can rapidly provide the information in the spatiotemporal context with the proper validations, in this way it has advantages to use during emergencies. In addition, even though geo-referenced data embody the small percent of the total volume of the SMD, it would specify reliable spatial clusters for the events, monitoring with optimized-hot-spot analysis and with the word frequencies of its attributes.
