Abstract: 

This talk will discuss our effort to quantify trends in a wide array of human behaviors using social media. It will showcase our Hedonometer http://hedonometer.org and its measurements of collective, dynamical patterns of happiness found in massive text corpora including Twitter, blogs, and song lyrics. Finally, I will also describe recent proof-of-concept studies using photographic data from Instagram to predictively screen for depression.
