The Wireless Emergency Alerts (WEA) service has been in use since April 2012, and there is a growing base of commercial mobile service subscribers who receive WEA messages. Therefore, it is an opportune time to assess to the public’s sentiment towards WEA and improve the communication of information related to the alert. Public sentiment towards WEA messages can be assessed by analyzing user discussions in online (e.g., news, blogs) and social media (e.g., Twitter, Facebook) platforms.
To gauge public sentiment towards WEA messages, the Homeland Security Systems Engineering and Development Institute (HSSEDI) used commercial tools to search online media sources for user comments and feedback. MITRE-developed research tools then analyzed this information to gain an understanding of the public sentiment related to WEA messages.
