Identifying Influencers on Social Media

This project aims to assess health organization’s influence on social media to derive dissemination strategy recommendations. We designed a four-dimensional framework to analyze topic-specific influence on Twitter. We applied this framework to 1M+ tweets from health organizations and analyzed their influence about dietary sodium intake, one of the risk factors of cardiovascular diseases.

This project was led by Dr. Yanfang Su from University of Washington, School of Public Health
