hi guys --
thought you might like to know -- I've recently added code to pluginize
SpamAssassin's default Bayesian-style probabilistic classifier, allowing
other trainable classifier implementations to be switched in in its place.
Given last year's TREC results (congrats ;), the OSBF approach is the
first candidate I'm trying out. If you're interested in tracking
develoment, the issue tracker is at:
http://issues.apache.org/SpamAssassin/show_bug.cgi?id=5686
(The http://www.siefkes.net/ie/winnow-spam.pdf paper has been the main
source of data on the algorithms, btw. I suspect it may be a little
out-of-date w.r.t. current practices, though...)
Cool! Both OSBF and Winnow use OSB for tokenization, but other than that
they're quite different filters :). For more details on OSBF, please check
http://osbf-lua.luaforge.net/papers/OSBF-Lua_VBFeb07.pdf and
http://osbf-lua.luaforge.net/papers/osbf-eddc.pdf.
If you need any help with pluginizing OSBF-Lua, I'll be glad to assist :).
