Mapping Voynich connections through rare tokens

rare and semi-rare tokens

I am interested in this. But how do you define rare and semi-rare? Is it words that occur only 2,3,4... times in the manuscript? What is the bar for a word to no longer be rare?

I took tokens that appear between 2 and 10 times all over the MS. Hapax legomena do not give any information about links. And tokens very used give noise. The maximum of 10 is arbitrary. I could have chosen 4, 10, 20...
