Subject Re: Automatically extracted CouchDB FAQs

Interesting project.  :)

I didn't get a very strong sense of correlation between the topic
categories and the questions in them.  For example,
"Questions & Answers about Couchdb, Couch, Replication, Databases and Database."

Had the following question:

"I'm looking for a recommendation for ruby gem that will enable me to
use couchdb from rails. I'd like to have couch documents be modeled by

This didn't have any mention of replication (or databases), so I can
only guess that it was clustering on "couch" or "couchdb".

Do you do any screening of common terms from the clustering?  I'd
imagine that if you looked at the user@couchdb mailing list, you could
find a list of very common terms (like couch, couchdb, database, etc.)
and discard or ignore those when trying to cluster the messages (in
the same way that words like "the" and "and" shouldn't be used).
Basically, a per-mailing-list set of generic terms.

The questions and answers themselves seemed to be a nice, readable "I
have X problem" "here is an answer" pair, so that was cool.  :)
