Of course, it does mean that if you ask Deep Mind about the cause of anything negative it will probably tell you "immigrants".
I wonder if it has explicit knowledge that they'll always remove a proper noun. Eventually the daily mail will write some article about a place causing or curing cancer, and the poor thing will break down trying to find X in X causes cancer from that corpus :)
On another note, I wonder if they could train it on Buzzfeed-esque content without changing the headlines. "You won't believe who Jeremy Clarkson punched!" -> the answer
Anyway, how about using Wikipedia instead? I can only guess they're using the Mail because they think it's funny.
Ironically, given your self-professed superior tastes in reading material, Deepmind seems to have a better ability to read, comprehend, and answer questions about articles than you do.
Deepmind is cleverly converting the Daily Mail article summaries into questions by removing a proper noun. For example:
Question: Producer X will not press charges against Jeremy Clarkson, his lawyer says.
Answer: Oisin Tymon
They are using the Daily Mail corpus to develop their algorithm, and that's smart. They aren't relying on it as an important source of information. Maybe all you guys with the dismissive comments have a better idea?
