[Article] Entropy Analysis of Questionable Text Sources by Example of the Voynich Manuscript

[ReneZ]

I haven't read it completely yet (not all pages are visible), but from the initial description it appears that they are using the modern concept of a cipher, i.e. they assume that a cipher has the property of equalising all character probabilities. This is what a modern cipher would do, and this is what the Voynich MS does not have.

It is one of my pet peeves that the concept 'language vs. cipher' is problematic.

If the MS text is a cipher, in particular a simple cipher, then it is also language.

There is no fundamental difference between writing a text with an invented set of symbols, or a language with an unknown alphabet.
What matters is if the language that has been represented using these symbols is known or unknown, or in fact not a language at all.
