Uses of ICT to Impact Organizational and Operational Challenges in Disaster Management

Current uses of ICT in disasters • Patient tracking (akin to logistics ) • Assessments - epidemiologic / need / damage • Geolocating areas of need • Communications within organizations • Capturing and sharing data • Incident management

Patient tracking (logistics)

WIISARD LA Lenert, D Kirsh, WG Griswold, C Buono, J Lyon, R Rao, TC Chan. Design and evaluation of a wireless electronic health records system for field care in mass casualty settings. J Am Med Inform Assoc. 2011;18(6):842-52. Epub 2011 Jun 27

Assessments - epidemiologic / needs / damage

Assessments - epidemiologic / needs / damage

Geolocating areas of need

Communications within organizations

Capturing and sharing data

Challenges to Sharing Information • Structure and motivation of the agencies • Leadership capabilities • Social / political structures of the affected area • Needs drive communication – needs for fundraising lead to competitive motivations

Signs of poor collaboration • Process is confused with results • Misallocation of resources • Maldistribution of teams • Resupplies not coordinated between groups • Survivor problems evolve to a critical state

Incident management

Leading ICT challenges in disaster response • perceiving survivors’ needs in near real-time • assessing damage geographically • creating greater horizontal and vertical integration of the response community

Refunite Perceiving survivors’ needs in near real time

Perceiving survivors needs – text analysis • Natural Language Processing - the Holy Grail • Currently uses two methods: probalistic topic models parallel bilingual corpora • MechanicalTurk method of crowdsourcing translations not sustainable

Probalistic topic models Start with 2 billion tweets Train a binary classifier to search for all terms related to “flu” with 5,100 training examples fever/ sneeze/ cough/ pain, etc = 1.63 million hits, Tweets categorized as ailments, symptoms, and treatments. Excludes “confusers” – “I got Bieber fever”

QCRI’s people trained algorithm classifies large volumes of texts into various categories for individualized attention by programs like micromappers, and CrisisTrackers

Bilateral parallel corpora Used to teach computers languages Includes a known language next to the other ‘slanguage’ Builds similarities (essentially the Rosetta stone in cyber age)

Providing integration – horizontal and vertical Integration requires communication Organization requires situational awareness
