Finishing off

In order to provide a good quality error assessment of the classifiers abilities.
I've retrained it on 10,000 BMC sections and used this to classify 10,000 PMC sections.
These two section sets should be mutually exclusive. However i'm not sure they are, because PMC distributes BMC content. I'll have to look in to this overlap.

Anyway here is the result

Sect Corr Incor Precis Recall F-Measure
INTROD 2308 839 0.7334 0.8809 0.8004

not bad considering that when you train on all sections (over 300,000) then you get this for 10,000 classifications.
