HURRICANE SANDY RESPONSE: $60+ Bln in damage

Does anyone know how to donate clothes to hurricane #Sandy victims?

Consequence: Creation of 2nd Disaster

• Resource demand-supply mismatch

Time to Start modeling Citizen Behavior for Social Impact!

• Data challenges:

Ambiguity

Sparsity

Diversity

Scalability

Need  for  the  Solution   at  the  intersection

Conclusion

• Start from organizational information needs to create Big Data systems for social impact

• Interdisciplinary Research a necessity!

• Less is More! -- We need to focus on actionable data, not Big Data deluge
