Matt Clausen on 19 Mar 09In these visualizations, a given text-the "specimen"-is compared to some larger group of texts-the "normative" text-using the Dunning log likelihood statistical analysis, which gives weight to words in a text according to how their frequency of use in the specimen text differs from the norm. All visualizations feature a cloud that varies from gray to blue. In this cloud, the size of the word corresponds to the number of times the word was used in a given address. The word's color depends on how statistically unlikely the word is in the normative text; in other words, a blue word was used more in the given speech than in the others it is compared to.
