Until this weekend. I spent a few (okay, more like eight) hours putting together a tool with Processing that would examine some of the similarities and differences between the two articles. The most interesting data ended up coming from word usage analysis (I looked at sentences and phrases as well, but with not much luck). The base interface for the tool is a XY chart of the words – they are positioned vertically by their average position in the articles, and horizontally by which article they occur in more. The words in the centre are shared by both articles. Total usage affects the scale of the words, so we can see quite quickly which words are used most, and in which articles.
