[development] Auto-tagging a large amount of content

[Brian Vuyk]

Hello all.

We have a site we are migrating to D6, and it has a very large amount of 
text content that we've imported. We are trying to find a good solution 
to auto-tag all the migrated content. Obviously, there is a bunch of 
modules that do term extraction / tagging in the  d.org modules list, 
however, there is little in the way of comparison of the various 
modules, and to test them all properly could take days / weeks.

So, what has everyone used in the past? Any gotchas we should be looking 
for?

Note: This is for very short term use - once the migrated content is 
tagged, new content will be tagged manually. Also, ideally we want 
something that uses a single 'tags' vocabulary instead of creating new 
vocabularies for people, locations etc (ie, like OpenCalais does).

Thanks in advance for any recommendations.

Brian
