Yes nimdoc, rather uncanny I agree. Anyway I think we are a long way from Lingua::Lit::Condense yet but it would great for students indeed.
Imagine,

condense prideandprejudice.txt
"Human bonding is complex"
condense oneflewover.txt
"Insanity is relative"
condense 1984.txt
"Government watches people"

cool!

Anyway, I searched ibiblio/gutenberg and turned found no lunch nor on Google. Which confirms there is no free lunch. I found a couple of excerpts though to cat together. They were formatted pretty weirdly so a quick blast with

perl -pi -e 's/\W/ /g' lunch.txt
[download]

and we lost all the punctuation, which imho is best for this sort of pseudo science (the loss of symbols to untrapped punctuation outweighs their syntactic value).

Anyway Burrows ....

I have picked the choice few sentences out of 15 or so, truncated some,

Old Pete men suck the Florida tan the same about you
taboos curses and subway is lurking in Washington Square a cell of rotten
he has scored he cruises the same dirty junky he hangs off
Thanks kid I am evidently his sharkskin suit
And the bodys string of inquiry ruling that anesthizes his enveloping presence
all over from shooting in my kid I ll wipe your release

- absolute filth imho, but who should concerned mothers sue? Mr Markov or Mr Burrows?, or Me?.

Still searching for Joyce.
