Re: [Demexp-dev] Issues on classification

I think we must decouple the keywords attached to a Question from the
different hierarchies of keywords used to reach this Question.

The keywords would be used to attach some semantics to a Question.

A hierarchy of keywords would be used to navigate into the forest of
keywords, grouping them by common topics, i.e. related subjects.

At least it was the main idea behind my first design using bit
vectors. However, several issues are raised when the classification
hierarchy evolves. We will have to discuss this in front of a white
board.

I have not reached yet this level of design, i.e. interaction with the
user to create new categories and extend the hierarchy. I'll tell you
then what seems to me the easiest. A priori, I think the first choice is
simpler.

Thank you for your feedback.
