Crisis Response Coordination in Online CommunitiesWhom to coordinate with, Why to coordinate and How to coordinate
Motivation
• During recent crises, citizens (sensors) are increasingly usingsocial media to share variety of information- situation on theground, emerging needs, donation offers, damage, etc.
• In such a dynamic community, how to extract actionablenuggets from the social media streams to aid relief efforts?

a. Coordination here means managing the competitive intentional behaviors (e.g. needs, offers)b. Psycholinguistic cues help to filter messages with higher information gain for coordination [1]c. Domain dependent analysis helps to understand the context of intentional behavior and
therefore, organize information in semantically rich data inventories [2]d. Contextual queries (needs against offers, vice-versa) across space and time help to generate
recommendations for both responders as well as informal social community actors [2,3,5]e. Interactive engagement interface with spatio-temporal-thematic and people-content-network
analyses allows coordinators to prioritize what to focus and whom to engage with [2,4,5]Application: This framework can be applied to coordinate information seekers vs. helpfulknowledgeable users and lurkers in domain-specific forum communities (e.g., Diabetes disease)

A big challenge is the very small signal to
noise ratio!How to transform the micro-
level (tweets) signals into actionable nuggets for macro-level analysis (coordination)?
