Systems developed

Along with my collaborators and students, I have developed several web-based systems for various practical tasks. Here are some of the systems developed by us (in roughly reverse chronological order).

NARMADA (Needs and Available Resource Managing Assistant for Disasters and Adversities) -- system for identifying resource-needs and resource-availabilities in a post-disaster situation from Twitter, and for suggesting how to match the needs with the availabilities
