I read through you post once again and figured out that I didn't probably answer all your questions in my previous reply.
First read about projects we have been using Wandara to:
About simplifying extracted information. Wandora has some tools that modify topics and associations in a way you could consider simplifying, even refining. However, it is always user's responsibility to interpret what topics and associations actually mean and then act according to the interpretation. What Wandora can do is to support user's will as well as possible. Thus we have included Wandora a large set of tools used to modify topics and associations. If tools are used in right context, the information in Wandora is really refining.
I already answered the question about 3D visualization. I would not consider Wandora as visualization software.
About similar programs. Well, you could think all Topic Maps and RDF editors similar to Wandora. See Protege (http://protege.stanford.edu
) for example.
About the usage of similar applications in industry, government and NGOs. Look at the supporter list of Protege (see http://protege.stanford.edu/aboutus/aboutus.html
). Wandora is also used in Finnish art museums to publish artwork related information (see http://kokoelmat.fng.fi/wandora/w?action=gen&lang=en
