Phew. It's ended up taking somewhat longer than I expected it would, but I'm confident this will provide a firm foundation for lots of interesting and useful semantics work in the VO in future.

Powerset
An interesting way to extract information from wikipedia, where you can try natural language queries:
http://www.powerset.com/
It retrieves relevant articles, and highlights the most relevant sentences within articles.
I got interesting answers for:
"What is a standard candle in astronomy?"
"When was the first supernova observed?"
But sometimes the results are more precise, giving you the exact answer !
"Who discovered the neutrino?"
"Who killed kennedy?"
"When was Albert Einstein born?"
