Semantic look-up in the New York Times

The NYT has a lookup feature provided by ask.com - just double click on a word and an explanation pops up. It didn't try to disambiguate the word Washington, going straight to an article on Booker T Washington, whom Washingto is not named after.

A complete restructuring of NYT in RDF might solve this (someone recently proposed re-working the UK mapping system to get lorries to avoid a particular village near Bristol). But then so does a right click powered (I'm using a Firefox extension) search of Google which takes me pretty directly to a Wikipedia article.
