Inside the Voynich Network: graph analysis

[quimqu]

It'd be interesting to plot the probability distribution of the degree of each node. I think it could paint a bigger picture than cond. entropy alone. I expect Voynichese to have a more multimodal-like distribution than the other corpora, but it's just a wild guess.

Great job by the way 

Thank you RadioFM,

it is an interesting point of view that you give here. Luckily, this is easily calculated and plotted. Here you have the degree distributions for several corpora, in log scale.
   
The result is quite revealing: all texts follow a similar heavy-tailed distribution, meaning that most tokens have few connections while a small number of words act as hubs.
The Voynich and Torsten Timm texts show almost identical shapes and very close statistics (mean and median degree around 20–90). They both sit between the compact structure of the French medical and scholastic Latin texts (around 60 mean degree) and the more rich / prose texts like Culpeper or Tirant lo Blanch (mean degree 300–500).
In other words, the Voynich doesn’t look random at all (neither Torsten's, because it follows creation rules). Its structure follows the same kind of scale-free law that natural and technical texts do, just with a bit less connectivity than full prose.
