description
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. H. Purohit, A. Hampton, V. Shalin, A. Sheth, J.

The Coordination ChallengeThe Coordination Challenge
How can emergency responders determine greatest need?
Who in the informal community on social-net can help?
Which people should be sent where?What can remote outsiders do?How can someone solicit help when
emergency services are overwhelmed?

Coordination in Dictionary: “the harmonious functioning of parts for effective results”
An excerptAn excerptAddress by Commander of Joint Task Force Katrina, Lt. Gen. Russel L. Honoré (Ret.) at
Wright State, Feb.1,2012 :
“.. 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!

Types of Organizations Types of Organizations Working Together Working Together
• Formal• FEMA, EMTs, Hospitals, Law Enforcement,
Public Safety• Informal• Local Communities, Churches, Suppliers
• Hybrids• Red Cross, DERA (Disaster Preparedness
and Emergency Response Association)
• Differing structures for command and communication exacerbate the coordination challenge.

Preliminary ResultsPreliminary ResultsDiscrimination metric for coordination indicative
candidates: D-prime (values range from 0 to 1.25)• Promising heuristics• Pronouns, length of the candidate set
• Degree of Discrimination• RT > Reply > @Addressee
• Corpus Dependent• Possible Socio-Cultural Influence
• Variation w.r.t. Decision Criterion in D-prime analysis• Examine distribution assumptions
• Explore sophisticated heuristic combinations• Regression modeling to quantify degree of coordination

Current Analysis• 0.55M topical twitter posts• Events with varied social significance, spanning
over different time periods• Parallel Computing paradigm for implementation
Work In progress• Current analysis done offline to build solid
framework but objective is to bring it to near real-time and integrate with visualization tool to help emergency response teams
