i'm asking since i'm using outlook spambayes wc is pure python....

Yes I finished porting the code and it seems to work for the Robinson
method although what I haven't done yet is verify that it produces the
same results as Reverend, i.e. have I ported it properly? Using the
Robinson-Fisher method doesn't seem to work so I think I need to go
back and look at my implementation of that algorithm again.
Here is Lucas' example using Bishop:
require 'bishop'
# The block passed here is actually mimicing the default behaviour however
# I add it here to show how the probability combiner algorithm is replaced,
# e.g. with Bishop::robinson_fisher
b = Bishop::Bayes.new { |probs,ignore| Bishop::robinson( probs, ignore ) }
b.train( "interesting", "here are some good words. I hope you love them" )
b.train( "uninteresting", "here are some bad words, I hate you" )
b.guess( "I hate bad words and you" ).each { |c| puts c.join( " = " ) }
outputs
uninteresting = 0.9999
Is there anyone with some python savvy who'd like to collaborate on testing?
