Guessing Someone’s Income from Their Tweets?

Can people guess your income based on your tweets? “We present the first extensive study where user behaviour on Twitter is used to build a predictive model of income. We apply non-linear methods for regression, i.e. Gaussian Processes, achieving strong correlation between predicted and actual user income. This allows us to shed light on the factors that characterise income on Twitter and analyse their interplay with user emotions and sentiment, perceived psycho-demographics and language use expressed through the topics of their posts.” The link goes to the entire paper; data files are available on Figshare.
