Character Classes

[MarcoP]

Just to be sure: the clusters are for any position, but relatively for 1 word only ?

h radar showing high for bf.y and af.t and af.y
q radar showing high for bf.o and af.0 and af.l

Could you give 1 word as an example for these please?

Hi David,
thank you for your interest!
The clusters are based on the data in the radar charts (same data as the csv attached You are not allowed to view links. Register or Login to view.). For each character, the frequency with which it appears before or after each other character are considered. The statistics are based on single unique words in isolation (words are not weighted on their number of occurrences).

The q radar only shows high for "before o". The graphing software plots a larger blue area because the value for bf.o greatly exceeds 0.2, the limit I set for the radar diameter (in the You are not allowed to view links. Register or Login to view. you can see the actual value for "q before o" is 0.88). Since the diagram is so small, the effect is that the blue are comes close to the confining lines for af.l and af.o: I understand that this can be confusing but I cannot think of a different way to plot all these numbers in a single image, I am sorry. 
I attach a slightly enlarged version of the q radar-chart.
