Does anybody know how the built in mac OS X summary service works? I played around with it a while ago and was fairly impressed with its accuracy.
Tonight I was working on a short story and ran the summary, at the most condensed setting the summary program gave me the one paragraph of the document that completely sums up the focus of the story. In short the story is about a person and the summary gave me the paragraph with the most well rounded description of that person. I was floored by this accuracy.
Does anyone know exactly how the summary service works? Does it look for repetition of words, references to to subjects, what?
If you know the answer share, if you have a good guess let's hear that too.
