Yes, clever. But if we're talking about sounds, how is rap/wrap rhyme while rap/rap isn't? Another question... We use imperfect rhyme (slant rhyme) so much in modern song and verse, isn't telling a computer to search for words that rhyme, like dog and log, missing half the rhymes? I'm leaning toward identifying phoneme echoes. True rhymes will show heavy phoneme echoes, while slant rhyme will show some. Weighting the phoneme echoes by whether they're in a stressed or unstressed syllable brings this out even more. Off-beat rhymes are subtle.

This is very interesting! If you might be interested in somewhat traditional publication, Journal of Humanistic Mathematics could be a good possible outlet for this kind of work. (I am one of the editors. And no, I don't spam everyone's content page to get submissions. This really looked interesting! In particular I'd love to know what motivated you to get into this project and what kinds of teaching uses you can envision.)

I was intrigued by your sentence: "The point is that the computer can detect features in poetry and visualize them." For me, this brings up interesting questions about poetry and its humanity. Can a computer that is aware of these poetic features eventually create "good poetry" (whatever that might mean)? Maybe a future project?

For those of you taking a close look at the diagrams, you may notice that the code links some rhymes most people would not consider rhymes. There are three main reasons for this. First, it counts repetition as rhyme, so "dog" rhymes with "dog." Second, the algorithm for splitting syllables is not consistent, which leads to some unexpected connections. Finally, we hear rhymes anchored to stressed syllables, while the code is linking echoes from any syllables, stressed or not. I am working toward a better version that will account for these factors. The current code is my project from the Wolfram Summer School. As such, it is richer than it would have been, including ideas from many people, but it also had to be published before I smoothed all the rough edges.
