RE: [Classifier4j-devel] Several questions regarding Classifier4J

I'm using Classifier4J as a spam email classifier in my
Webgate software (see http://webgate.sourceforge.net).

I don't know the answer to this.  From my dealings with it,
all results are stored in a database.

Well - the matching returns a percentage match I think.  So
you could test the returned result and say, for example.. that
a 0-.2 would be very good, .2-.4 good, .4-.6 moderate, etc.

I used teachMatch() and teachNonMatch() (i think thats the correct
method name) against known good and bad emails in my inbox.

Hope this helps!
