| Your example was quite convincing, so I think I will do it that
| way. The only drawback I can see is a bigger (but more detailed)
| topic map and eventually a more complicated navigation in it.

A precise ontology is harder to create, and does require more
information to be input, but the benefit is much much greater. Whether
it is the right approach or not depends very much on the application
and its domain.

However, as long as you realize that topics and keywords are the same
thing you can choose an ontology that has lower precision and still
get quite good results. 

(It's a little bit like DocBook vs XHTML.  DocBook gives better
results, but XHTML may be good enough in some cases.)
