We did some 'auto query generation' in our SemanticSever. The user draws 
a graph with some nodes labeled with a question mark, then the engine 
first builds the query for the users to make sure this is what they 
intended, then allows them to run the query. S-Server searches on many 
participating physical servers from the list you can maintain - it 
treats the Web as one "information space" hosted on many servers.

You can try S-Server directly at our site - www.semanticsoft.net. After 
login as a guest, the first thing you see is a "desktop" with a Start 
button like in Windows, but you are actually on our minuature 
SemanticWeb hosted on our servers.  Press Start button and select Help - 
this will help you to use this tool.

The  "canvas" (or "tissue", "media", "substratum") on which our Semantic 
Web is built, allows ontologies to be stored in a "transparent" manner 
so that the query engines "see inside" them while regular  digital 
artifacts are kept as blobs. "Folders" are just a UI simulation of 
Windows on this "canvas" - behind the UI you actually group resources 
(things) and, this manner, change the "topology" of the information space.

I would treat "understanding" of some content (like the content in GGG) 
as representation of that content onto such "canvas", because as soon as 
the content is onto the "canvas", the engines can query inside such 
content and they are  also aware of the context which is also on the 
canvas as Semantic Web formatted content.
