Task 5 : Classification of tweets self-reporting potential cases of COVID-19.

This new binary classification task involves automatically distinguishing tweets that self-report potential cases of COVID-19 (annotated as “1”) from those that do not (annotated as “0”). “Potential case” tweets include those indicating that the user or a member of the user’s household was denied testing for, symptomatic of, directly exposed to presumptive or confirmed cases of COVID-19, or has had experiences that pose a higher risk of exposure to COVID-19. “Other” tweets are related to COVID-19 and may discuss topics such as testing, symptoms, traveling, or social distancing, but do not indicate that the user or a member of the user’s household may be infected.

  • Training data: 7,181 tweets
  • Test data: 10,000 tweets
