If I were king of the world, with unlimited budget and unlimited
cooperation, I'd start with a taxonomy and domain experts. Let them define a
domain vocabulary (again I keep pointing to MeSH for medical literature).

Then, when new literature is published each month, run it through machine
analysis to identify new terms that start popping up in the literature
(e.g., XML a few years ago). Also identify relationships to existing
concepts or terms (similarity searches), and so on.  The domain experts
identify an alert level (e.g., 5 citations) and when a term or concept
exceeds that level, it's included in a monthly update they receive -- new
terms and concepts in the literature. They use that information when
updating domain vocabularies on a quarterly basis.

Using a pre-defined domain vocabulary is probably more efficient than doing
it all automagically using inference engines, machine analysis of schemas,
RDF, parsing and so on.

Look at the portals that migrated to a classification scheme, instead of
being simply keyword container searches.
