Narration structure as the tiebreaker between cipher & (synthetic) language

[-Job-]

The question is ready - what do we do to "observe" the narration structure? Actually that is the question that I was about to ask - does anyone know any computational methods of revealing narration patterns in unknown texts?

I expect that it will be difficult to do this without a tentative classification of the words in the text, but it's worth looking.

As you mentioned, a synthetic language would likely preserve grammatical features of the author's language, much more so than a cipher.

One possible avenue is to start by determining where the information bits are, and how they're distributed throughout the page.

Assuming that the synthetic language's encoding mechanism is consistent (i.e. words are always encoded in the same way), the distribution of keywords should be comparable to that of a plaintext.
