This is a summarized view of doctoral consortium presentation done at NSF SoCS 2013 PI meeting.
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 an evolving ad-hoc community, how can we extract actionable nuggets from the social media streams to aid relief efforts? This doctoral consortium presentation summarized in a poster shows a framework to analyze social media data and manage information to assist coordination by focusing on three important questions to answer: Whom to coordinate with, Why to coordinate and How to coordinate. It shows exemplary insights for needs and availability from the recent disaster events.

  1. 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! RT @OpOKRelief: Southgate Baptist Church on 4th Street in Moore has food, water, clothes, diapers, toys, and more. If you can't go,call 794 Text "FOOD" to 32333, REDCROSS to 90999, or STORM to 80888 to donate $10 in storm relief. #moore #oklahoma #disasterrelief #donate Want to help animals in #Oklahoma? @ASPCA tells how you can help: http://t.co/mt8l9PwzmO CITIZEN SENSORS RESPONSE TEAMS (including humanitarian org. and ‘pseudo’ responders) Coordination of needs and offers between seekers, suppliers and intermediate responders via automatic analysis Does anyone know where to send a check to donate to the tornado victims? Where do I go to help out for volunteer work around Moore? Anyone know? Anyone know where to donate to help the animals from the Oklahoma disaster? #oklahoma #dogs Matched Matched Matched Serving the need! If you would like to volunteer today, help is desperately needed in Shawnee. Call 273- 5331 for more infoVICTIM SITE 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)?
