The Usage of Twitter Data for Early Crisis Detection

The establishment of novel information and communications technologies, such as social media, has changed how individuals and organizations behave. Particularly during uncertain situations caused by natural or man-made disasters, people communicate and share information via social media. Emergency services could use published content of social media participants for an early detection of crisis situations and thus enhance crisis management. However, exploiting these information bears several challenges. To gain insights from large amounts of unstructured data in time-critical situations, emergency services are in the need of tools that enable them to gather, process, and analyze relevant information. In this research article, we follow the design science paradigm and propose a concept (artifact) of an early crisis detection tool. Based on expert interviews, design implications for the concept tool are derived. In addition, we conducted a design thinking workshop to evaluate the artifact, highlighting its practical relevance and usability.
