Looking for patterns in the words is meaingingless, so a pair of analysts created a formula that looks for global patterns in the frequency and clustering of words that might indicate meaning. So if you analyze "Moby Dick" you get high-entropy words like 'whale' and Darwin's 'Origin of Species' yields 'species' and 'varieties'.
Ummm, no kidding.
