Hi There!
I just read this post, interesting stuff.

I would like to add my 5 cents about unstructured information:
Talking about Unstructured Information (Ontology, Search and Taxonomy), the only software I know of where the software really works is InfoCodex. InfoCodex comes with a linguistical database with 3 Mio words and terms in German, French, English, Italian and Spanish. What does this mean? This means IC can actually do a cross-language search and find similar documents in another language. This is true-cross-language-search. Autonomy, Fast, OmniFind, none of those can do that. InfoCodex will also produce a Graphical Heat-Map of all the contents in any given collection. Also see:
