MT Talks

MT Talks is a series of mini-lectures on machine translation.

Our goal is to hit just the right level of detail and technicality to make the talks interesting and attractive to people who are not yet familiar with the field but mix in new observations and insights so that even old pals will have a reason to watch us.

MT Talks and the expanded notes on this wiki will never be the ultimate resource for MT, but we would be very happy to serve as an ultimate commented directory of good pointers.

By the way, this is indeed a Wiki, so your contributions are very welcome! Please register and feel free to add comments, corrections or links to useful resources.
