Crisis Response Coordination in Online Communities Whom to coordinate with, Why to coordinate and How to coordinate Motivation • During recent crises, citizens (sensors) are increasingly using social media to share variety of information- situation on the ground, emerging needs, donation offers, damage, etc. • In such a dynamic community, how to extract actionable nuggets from the social media streams to aid relief efforts? Hemant Purohit (advisor: Prof. Amit Sheth) Ohio Center of Excellence in Knowledge-enabled Computing (Kno.e.sis), Wright State University, USA 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. helpful knowledgeable users and lurkers in domain-specific forum communities (e.g., Diabetes disease) Approach Highlights Sponsored in part by NSF Grant#IIS-1111182, ‘SOCS: Social Media Enhanced Organizational Sensemaking in Emergency Response’ Second-costliest hurricane in U.S. history estimated damage $75 B 750,000 without power (NY) Hurricane Sandy 2012 285 people killed on the track of Sandy 20+ Million tweets in first week for #Sandy Social Media will aid the existing relief workflows, rather than replace!
