KentuckyFC writes "Stories are a powerful channel for communicating emotions. But while they have been studied in detail by generations of critics, there is little in the way of objective tools for analyzing and comparing their emotional content. That looks set to change thanks to one data mining researcher who has applied the process of sentiment analysis to novels and fairy tales that have been digitized on Project Gutenburg and the Google Books Corpus. The results show the density of emotions in different parts of a story and how the emotional 'temperature' changes throughout the tale. For example, this guy has used the technique to compare the emotional content of the entire collection of the Brothers Grimm fairy tales to reveal that the darkest story is a tale called Gambling Hansel; clearly a lesson to us all."
