Data Mining and Machine Learning Lab Beyond Crowdsourcing for HADR Huan Liu, Shamanth Kumar and Huiji Gao

Data Mining and Machine Learning Lab Outline ‒ Motivation –Crowdsourcing for Disaster Relief –Inadequacies of Current Crowdsourcing Systems –Our Methodology –Demonstration

Data Mining and Machine Learning Lab 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

Data Mining and Machine Learning Lab 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). Social Media for Crowdsourcing

Data Mining and Machine Learning Lab 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

Data Mining and Machine Learning Lab Inadequacies of Current Crowdsourcing Systems Information is hidden in massive and noisy data –N–Numerous social media sources –U–Unfiltered information can be hard to interpret –T–Too many messages can be overwhelming for intelligent decision making Lack of a common coordination mechanism –D–Different focus and capabilities of HADR agencies –H–Hard to optimize resource allocation and distribution

Data Mining and Machine Learning Lab 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
