This is cool - a button you can add to your blog that will automatically summarize the post for readers. I've seen systems like this before - basically the way they work is to give each sentence a ranking based on its salience - how many of the most important words it uses, for example - and then displays the five (or whatever) highest ranking sentences in order. There are different algorithms for selecting important words or phrases, and matching these to sentences. NRC was involved in something like this about ten years ago.
