<:> Uncertainization approach

Starting at the smallest scale of analysis, carry out an n-gram analysis (also taking account of disjunctive n-grams, i.e., `a b/c d', `e/f g h') and form a Markov model.

Find the smallest encoding of the data in terms of the n-grams found.

Treat the encoding obtained as new data and start again.

Continue until an encoding of a single element is generated.

Markov models obtained along the way then form a hierarchical structure.
