Thanks to all the students who showed up for the information extraction lecture today. It would certainly not have been any fun lecturing to the walls ;-)
To those who couldn't make it, the video as well as audio are available on the class page. I hope you will make time to watch or hear it. As I said, IE is one of the more active topics of research now, and I would hate for you not to know any entry into it--especially given that all you have done to-date provides you a pretty good infrastructure.
For Tuesday's last class, I plan to spend the first 45min or so discussing some issues in "information integration" and then then doing a quick wrapup.
The slides for the information integration are on line, but are likely to change by the class time.
