Colloquium: Opportunities from Social Media Data for Public Health

Date: 

Thursday, February 13, 2014 - 11:00am

Speaker: 

Mark Dredze

Host: 

Christophe Giraud-Carrier

Twitter and other social media sites contain a wealth of information
about populations and has been used to track sentiment towards
products, measure political attitudes, and study social linguistics.
In this talk, we investigate the potential for Twitter and social
media to impact public health research. Broadly, we explore a range of
applications for which social media may hold relevant data, including
disease surveillance, public safety, and drug usage patterns. To
uncover these trends, we develop new statistical models that can
reveal trends and patterns of interest to public health from vast
quantities of data. Our results suggest that social media has broad
applicability for public health research.
