A second hand account from a VentureBeat journalist is the best I could find [1]. As a researcher with more than a decade of experience in Natural Language Processing, what is described by the journalist in regards to the paper content seems to be non-controversial and nothing out of the ordinary from this kind of work. If anyone could find an actual leak I would be more than excited to have a look at it using my own eyes rather than filtered through someone else’s.
