Impact is also if others use the tools, our team is developing, without that we know about it :-). The below picture is from a presentation by the team of CAAS in the Chinese Agricultural Ontology workshop.
The idea behind this is the same as behind our multilingual semantic search assistant. It exploits the structured knowledge of the thesaurus against an unstructured corpus like Google. The work was the product of a PhD thesis and is unfortunately still not published.
It should surely be part of our project in using the mapping file between AGROVOC and CAT.
