Markov chain

to create texts for doorways

[Tsuren]

I have heard that people use "Markov chains" (that's a mathematical term) to make texts for doorways. Could anyone explain what how to use them?

A Markov chain is a mathematical method used for creating random text. Here is a good description of the theory of Markov chains for random text [cs.bell-labs.com].

I don't like Markov chains to produce random text for SEO purposes because I don't believe the output is good enough.
