“That particular genetic combination of swine influenza viruses has not been recognized before in the U.S. or elsewhere”

Situational Awareness: the ability of a group, organization, or individual to have access to everything they need to make active decisions to create results.

Monitoring Twitter with NLP

  • Processed 1200 Twitter posts (within the first hour)
  • Preprocessed to accommodate format

Schema: UMLS Semantic Types

  • Focus output
  • Schema for influenza epidemic

MetaMap and SemRep Output

  • Tweets: Texas confirms third case of swine flu

Results: Filtered through Schema

  • Disease or Syndrome: Influenza
  • Sign or Symptom: Coughing
  • Location: Mexico

…Basically they analyzed Tweets within the first hour of the outbreak in a calculated system (NLP) defined by some specific search terms to see when outbreaks were occurring, and how fast they were spreading.
