A collection of free datasets from Microsoft Research
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.txtThese 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 should only be interesting to people who plan to be academics permanently, or who don't plan to succeed at anything they do with it.You can't even open-source anything you make out of it, because open source software does not restrict the purpose for which it's used. You can't combine it with data under any Creative Commons license except CC-By or CC-0, because its restrictions are definitely not Creative Commons compatible.The truly insulting part is that you have to give an unrestricted license back to Microsoft for everything you make out of this data. You can't benefit from what you make out of the data, but Microsoft can, with no limitations.Whatever you make from this data, you can't benefit from it. Most other people can't benefit from it. Microsoft can benefit from it, and if they want to, they can just take it without crediting you.This is like an artist being asked to do something "for the exposure", by someone who will just take it and give you no exposure.
