[topicmapmail] Classification of occurrences using keywords

[Johannes Koppenwallner]

Hello,
I have a topic map with already defined topics and associations. Now I 
want to populate this map automatically with occurrences, which should 
be classified to the topics using keywords. (I know, a quite primitive 
way to classify.) To make this work, I have defined keywords for every 
existing topic. It would be nice to define the keywords/topic relation 
in the topicmap, so nothing else than the topic map is needed to 
classify documents. So my question is: What's the best way to model the 
relation between a topic and it's keywords?
Thanks in advance.

Johannes
