Framework to Analyze Coordination in Crisis Response Using Social Media

979 views

Published on

Social Media play a critical role during crisis events, revealing a natural coordination dynamic. We propose a computational framework guided by social science principles to measure, analyze, and understand coordination among the different types of organizations and actors in crisis response. The analysis informs both the scientific account of cooperative behavior and the design of applications and protocols to support crisis management.

  3. 3. wish i could help #tsunami what can i do for these people? #japanearthquake @clancycnn #WFP #Japan Milk for children is so needed right now, there's no milk in some stores & that shortage may be the worse. RT @ietweet: Japan's tsunami-ravaged hospitals run out of food, medicines : http://goo.gl/natY3
  4. 4. The Coordination Challenge <ul><li>How can emergency responders determine greatest need? </li></ul><ul><li>Who in the informal community on social-net can help? </li></ul><ul><li>Which people should be sent where? </li></ul><ul><li>What can remote outsiders do? </li></ul><ul><li>How can someone solicit help when emergency services are overwhelmed? </li></ul>Coordination in Dictionary: “the harmonious functioning of parts for effective results”
  5. 5. An excerpt <ul><li>Address by Commander of Joint Task Force Katrina, Lt. Gen. Russel L. Honoré (Ret.) at Wright State, Feb.1,2012 : </li></ul>“ .. the biggest helping hand comes from people in the local communities, they have resources to share, and no Emergency Response storage can store the things to the scale which is needed during critical time .. ” Lesson Learned: Better understand the dynamics of various actors involved and especially, informal communities forming outside the periphery of responder teams!
  6. 6. Types of Organizations Working Together   <ul><ul><li>Formal </li></ul></ul><ul><ul><ul><li>FEMA, EMTs, Hospitals, Law Enforcement, Public Safety </li></ul></ul></ul><ul><ul><li>Informal </li></ul></ul><ul><ul><ul><li>Local Communities, Churches, Suppliers </li></ul></ul></ul><ul><ul><li>Hybrids </li></ul></ul><ul><ul><ul><li>Red Cross, DERA (Disaster Preparedness and Emergency Response Association) </li></ul></ul></ul><ul><ul><li>Differing structures for command and communication exacerbate the coordination challenge. </li></ul></ul>
  7. 7. Potential Coordination Methods <ul><li>Impose pre-structured communication protocol on the informal organization.    </li></ul><ul><ul><ul><ul><li>Mine natural linguistic patterns in user interactions for formal organization needs. </li></ul></ul></ul></ul><ul><ul><ul><ul><ul><li>Collect tweets </li></ul></ul></ul></ul></ul><ul><ul><ul><ul><ul><li>Detect coordination </li></ul></ul></ul></ul></ul><ul><ul><ul><ul><ul><li>Summarize for formal organization </li></ul></ul></ul></ul></ul>
