Title: Remote Sensing of Emotional States in Real-Time — http://hedonometer.org

Abstract: Using human evaluation of the happiness of words, we analyze a diverse set of large-scale texts which reflect cultural experience including 50 years of music lyrics, 10 million weblogs, and 50 billion status updates from Twitter. We find that happiness rises and falls with age and distance from the Earth’s equator; the 2008 Presidential Election was the happiest day in the blogosphere in the last 5 years; and that a diverse collection of languages exhibit a pro-social bias. This talk will describe these results in the context of our Computational Story Lab’s ongoing efforts to understand the geographical and topological dynamics of large-scale socio-technical phenomena.
