There's something like frequency information in WordNet, it could probably
be used to ignore the uncommon meanings.

I added "query expansion" which takes in a simple query string and for
every term adds their synonyms. There's an optional boost parameter to
be used to "penalize" synonyms if you want to use the heuristic that the

I'll try it.
Small optimization suggestion: use int[] with a single element for that

How do you model/store your taxonomies/ontologies regarding your
datastructure ? Do you use Java datastructures or RDF?

Hi,
expanding a query is basically done by generating a new one an reusing the
existing terms plus the selected one from your ontology/taxonomy. There has
been discussion here before and you should search the archive for that.
Extracting and using the right bit from your ontology is basically a ta
Hi Everybody,
I wish to use an hierarchy of concept provided by an Ontology to refine
