I agree with you that a "simple" classification based solely on
keywords is far from ideal. After thinking, one main problem is that
a question can belong to several categories, which makes the parsing 
more difficult. Of course, in the S3 version (Stable, Scalable, Secure),
questions will belong to several categories, but the U2 version does
not need to have this feature. Also, as you mention, it would be nice
to be able to hierarchically parse the database in the GUI in U2 version.

Alternative possibilities:
-The user chooses the category (possibly creating a new one). We know that this
will no longer be feasible in a large scale system, however, smaller groups
wanting to use the DemExp independently may like this feature.
-The hierachy of categories is pre-set and/or evolved by a "person in charge"
and the user can only put his/her question in an existing category

Would this make the implementation easier?

I like the U2 name. I guess the ultimate version can be named T4 (Too much
Trouble To Think about).
