BTW Matt, WRT:

"a system with a modicum of world knowledge would be off to a running start knowing that a person was being discussed (simple entity extraction would deal with this)"

Thought I'd experiement w/a decent entity extractor to see how it would deal w/the sentence "ian anderson was born in". I went to ClearForest's SWS Web interface (http://sws.clearforest.com/SWS.htm) and copied that sentence. While generally speaking on a larger corpus of text it performs pretty well in terms of finding proper names, on just 5 words it found no recognizable entities. When I put the sentence "Ian was born in 1947 in Dunfermline, Fife, Scotland", it found "Fife" to be a city and "Scotland" to be a country.

Interesting hunh? Tough to look too far down the road when this level of functionality is still far fm resolved adequately.

FYI, just tried the Named Entity extractor (http://www.alias-i.com:8080/lingpipe-demos/ne_en_news_muc6/textInput.html) on LingPipe w/the same sentence as I tried w/SWS and it too didn't pick up any entities there.
