The Olympic Emotion Project

Where there are data, there are data scientists, analyzing and looking for new applications.

Researchers at École Polytechnique Fédérale de Lausanne (EPFL) developed a Web app that uses tweets about the Olympics to visualize in real time and record how people are feeling. Emotions generally considered more negative are blue or red, while more positive emotions have brighter colors. Disgust is purple, shame is dark blue, and happiness is yellow (obviously).
