They don't make it easy to find out what the Microsoft Research License Agreement is, when they put it behind a login wall on a site that doesn't work with ad-block. But this appears to be a copy of it: http://www.cs.toronto.edu/~aditya/langid/msrla.txt These license terms are a trap. Nobody should ever accept them. You can't use the data for commercial purposes, which is harsh enough on its own -- it means the data…
It'd also be useful for someone farting around with machine learning who isn't anywhere close to being at a point of shipping anything to anyone else.
What you can benefit from is what you learn while using the data. Then you start a new project using what you've learned, and using different data.
