Social media such as Twitter and Facebook provide a rich, if imperfect portal onto people's lives. This session will cover how we analyze tens of millions of Facebook posts and billions of tweets to study variation in language use with age, gender, personality, and mental and physical well-being. Word clouds visually illustrate the big five personality traits (e.g., "What is it like to be neurotic?"), while correlations between language use and county level health data suggest connections between health and happiness. Similar analyses are widely useful in understanding people's thoughts and concerns.
Joint work with Johannes Eichstaedt, Andy Schwartz, Peggy Kern, Greg Park and Martin Seligman.
