To the extent that abuse is a medical diagnosis, it would be trivial for a computer to make that presumptive diagnosis. In fact, if Watson is truly performing at the level of an M2, it probably already can.
Actually, I'd think the first signs of abuse would be the most difficult things for a computer to diagnose. Excuses are given, nobody says anything about violence, the person slipped, but the non-verbal cues might raise a red flag.
I'm not sure how much common sense world knowledge would be in Watson. "Hey doc, I got a pain in my chest while watching the football game vs Cal at Memorial Stadium." The DDX might include angina despite the computer being unlikely to know about a fan's emotions or environment of a football game.
