Researcher uses AI to unravel the mystery of Shakespeare's co-author

After all these years, someone might have figured out exactly how much Shakespeare worked on one of his last plays. It's long been suspected that Shakespeare didn't write the whole of Henry VIII, but now, thanks to machine learning, we could know just how much he outsourced to a playwright friend. For those of you who aren't up on your Shakespeare, the notion that Henry VIII may have had more than one formal author is also a very old one, born from the fact that some of the scenes just don't "sound" like Shakespeare. His co-author is generally supposed to be his successor, John Fletcher. They also collaborated on The Two Noble Kinsmen: both of their names were on the published edition.
