What did work is using on page data. Theoretically, nobody can give a definitive answer, but after reading Google's AdSense overview, and reading the Applied Semantics whitepapers about their CIRCA technology, I don't think they use it.
and let me put your scientific comments into simple words:
you, publishers, have to produce as much text as possible to get proper targetting. Nothing, neithr tags, nor URLs with keyword, will replace maximum number of text. This is simple rule of thumb for AdSense: if you need good targetting, then place as much text as possible.
