  1. Beyond Crowdsourcing for HADR Huan Liu, Shamanth Kumar and HuijiGao

  2. Outline • Motivation • Crowdsourcing for Disaster Relief • Inadequacies of Current Crowdsourcing Systems • Our Methodology • Demonstration

  3. Motivation • Catastrophic Disasters: • Haiti earthquake/cholera. • Middle–east revolutions. • Japanese tsunami and earthquake. • Social media for disaster relief: • Revolutionize the role of media • Information disseminator • Communication tool

  4. Social Media for Crowdsourcing • Crowdsourcing leverages participatory social media services and tools to collect information • Crowdsourcing allows capable crowds to participate in various HADR tasks. • Crowdsourcing integrated with crisis map has become a powerful tool in humanitarian assistance and disaster relief (HADR).

  5. Applications of Social Media & Crowdsourcing for Disaster Relief • Uses for Individuals • Find missing people • Early warning of disasters • Get information on relief work progress • Find location of shelters & medical resources • Get in touch with officials and relief workers (more ways to ask for help) • Uses for Agencies • Get situational awareness first hand from citizen reporters • Coordination platform • Send updates on progress of relief work • Discredit rumors • Obtain public feedback

  6. Inadequacies of Current Crowdsourcing Systems • Information is hidden in massive and noisy data • Numerous social media sources • Unfiltered information can be hard to interpret • Too many messages can be overwhelming for intelligent decision making • Lack of a common coordination mechanism • Different focus and capabilities of HADR agencies • Hard to optimize resource allocation and distribution

  7. How We Can Help • Building crowdsourcing systems to aid in event analysis • Automate data collection & data storage for event analysis • Preprocessing and summarize collected data for quick interpretation • Visualize crowdsourced data • Building a coordination system for better collaboration • Coordination mechanism designed for disaster relief • Intelligent crisis map view to facilitate the response • Enhancing communications among agencies

  8. Our tools • Crowdsourced information • Groupsourced information • Multi-layer requests view • Inter agency coordination • Crowdsourced information • Feedback information source • Situational awareness • Post event analysis • Crowdsourced information • Situational awareness • Near real time information aggregation • Post event analysis ACT BlogTrackersTweetTrackers

  9. ACT (ASU Coordination Tracker) Four Modules • Request Collection -Crowdsourcing -Groupsourcing • Response • Coordination • Statistics

  10. BlogTrackers Three modules • Data Collection • Crowdsourcing • Analysis Module • Visualization

  11. TweetTrackers Three modules • Data Collection • Crowdsourcing • Analysis • Visualization

  12. Acknowledgments • DMML members, in particular, Geoff Barbier, Fred Morstatter, and Patrick Mcinerney. • This work benefits from the ONR’s vision on Social Computing, Digital Revolution, and HA/DR. Office of Naval Research
