Perfect? No. Good enough? Maybe?

[Wally Hartshorn]

I suspect the question isn't "Is there a way to do this and get 100% correct results" (answer: no), but rather "Is there a way to do this and get perhaps 60% correct results" (answer: ???). Yes, it might get tripped up by "time flies like an arrow" vs. "fruit flies like a banana" stuff, but if you set the bar lower, could something useful be created? (As to whether "60% correct" would be useful, that will be a question for your friend to consider.)
