The wayback machine has archived it a number of times - this it what it
looked like in December:

http://web.archive.org/web/20161205072328/http://research.microsoft.com/en-us/um/beijing/projects/letor/

Neither of those URLs seems to be an exact replacement - I couldn't
trivially find a current version, perhaps there isn't one.

Parth, any idea?
