Scientists use AI to find out how much of Henry VIII Shakespeare wrote

Artificial intelligence has been used to determine how much of the play'Henry VIII' was written by William Shakespeare and how much was penned by John Fletcher. Fletcher replaced Shakespeare as the house playwright for acting troupe The King's Men in 1616 and, while literary experts have long known Henry VIII was a collaborative work, they didn't know how much of the work was written by Fletcher. To solve the puzzle, Czech artificial intelligence researcher, Petr Plecháč, decided to train a machine-learning algorithm on the works of Shakespeare, Fletcher and other contemporary writers. He then'let it loose' on a the text of Henry VIII to see if it could determine the true authorship of each scene. Mr Plecháč says the algorithm proves that Fletcher wrote several scenes - including much of the second act.
