Speakers: Dr Lewis Mitchell (University of Adelaide)

Topic: Happiness and the shapes of stories

Abstract: The advent of so-called ‘sentiment analysis’ techniques in recent years has led to novel methods for extracting information from large, unstructured, text-based corpora. In this talk I will review work we have done using one such tool called the ‘hedonometer’, developed to measure population-level happiness from text. I will talk about recent work applying such tools to examine the emotional trajectories of stories such as films and books, and how meaningful features of stories such as genre are encoded within the trajectory of the story. We will look at examples of emotional content analysis across literature, film and even social media, and discuss ways in which these simple algorithms may be used for prediction of population-level events.

Dr Lewis Mitchell is a lecturer in applied mathematics at the University of Adelaide. His background is in applying mathematical models to predict complex physical and social systems, in particular techniques for assimilating real data into predictive models. In the past Lewis has worked on ocean wave models and ensemble data assimilation methods for forecasting in chaotic dynamical systems such as weather. Since being introduced to the fields of complex systems and computational social science during a postdoctoral fellowship at the University of Vermont, Lewis has started to work on sentiment analysis for social media, human dynamics, and disease prediction. Some of his current interests involve understanding information flows across social networks, and the interaction between both mass and social media on the spread of diseases.

Feel free to forward this meeting notice to colleagues, all welcome.
