Automagically Generated Summaries of MIT OCW Algorithms Lectures

I'm really interested in how you did the automagic summarization? Is there some sort of public algorithm, or did you make something yourself? If so what/how?<p>The reason I'm asking is because I was thinking of making a summarizator but ended up realising I have no idea how to even begin making one.

Why don't you just read introduction to algorithms?

As promised here yesterday on the MIT Video lectures - Introduction to Algorithms discussion thread -&#62; <a href="http://news.ycombinator.com/item?id=1751181" rel="nofollow">http://news.ycombinator.com/item?id=1751181</a>

This is nice, though some formatting would make it easier to read. In IE7x there is almost no whitespace on the right margin. On my big monitor it is close to wall to wall text.
