Excellent. For others sitting on the fence, I am not asking for a lot of
time or coding (though I will not turn it away), but more for help gathering
data. I do not have an active Drupal installation at my finger tips (yet),
so I need assistance with data collection.

I'll check it out. Perhaps the classifiers should be factored out into a
separate component module. I'll look at the feasibility of that.

Thanks. I'll investigate.

I agree it is long, but I want to be honest about the project. My experience
has been that creating a successful machine learning model is a slow,
iterative process. One refines the data collection, and then modifies the
model, tests, and repeats. Depending on your hunches at the beginning this
can be either a quick process or a painfully lengthy one.

This is good advice. I hope to go from "I have an itch" to "I have a
concrete task on which to concentrate" soon. If anyone has suggestions, I'm
all ears.
