Hey code4lib! I've been working on some text visualizations recently and realized that there's probably at least a few people on this list who might find this work interesting. The first is a visualization of line similarity in T.S. Eliot's "Four Quartets" http://willkurt.github.io/four_quartets_visualized/ This project also contains a detailed description of what you're actually seeing (essentially cosine similarity matrices). The second is a similar visualization of line repetition/similarity in the lyrics of every Vampire Weekend song (broken out by album): http://imgur.com/a/ZFxFo A super brief explanation of what you're seeing: each square represents the similarity between any two lines. For example [1,2] would shows how similar line 1 is with line 2. This explains the diagonal lines (line x is always identical to line x) as well as the symmetry (the similarity [x,y] is the same as [y,x]). As a next step I plan to create an interactive version of this, as well as an easy way to automate the creation of this type of visualization. Enjoy! --Will
