Oh yes, now that you mentioned them, I remember studying Markov chains
in linear algebra, I think. I've also heard this called a histogram or
ngram, but I've never looked into the terminology at all. I have never
done this at the word level, because I was simulating randomly-typing
monkeys when I played with this. And for the monkeys I wanted letter
generation. I will have to play with word generation too, because it
just never occurred to me!  :-)
