Spectators are increasingly using social platforms to comment about big public events such as sports games and political debates. The quantity of such data is too overwhelming to be processed by a human. During the 2012 Olympic games, 150 million tweets were generated on Twitter alone.
To understand the public's perception of these events, it is important to recognize the subjective content revealed in such "big data". This has motivated us to develop a system to automatically detect and visualize the patterns and trends of user sentiments as expressed in their comments, and how their sentiments evolve over time. Previous work in opinion mining has addressed some of these issues. But the majority of them identify only two categories of emotions: positive and negative, leaving a more detailed and insightful analysis to be desired.
In this talk, I describe EmotionWatch, a data mining and visualization tool, that helps people make sense of spectators’ emotional reactions in public events using a fine-grained, multi-category emotion model.
