Question answering by a machine such as Watson is not very useful unless
the system can explain its answers. Thus i am disappointed that IBM's
"explanation" of its error in Final Jeopardy does not explain why it
chose its answer. (01)

This explanation is little more than "Jeopardy is hard":
* Category names are tricky and their significance is downgraded.
* There are cities named Toronto in the US
* Toronto, Ontario, has an American League baseball team. (03)
This does not explain why "Toronto" was selected as a response. (04)
In the IBM ads accompanying the show, they discuss Watson being used
for diagnosis -- not just for pointing out information that a doctor
may want to look at for a case. However, without explanation for
a diagnosis -- or even for a recommendation for reviewing some paper,
such use seems quite improper. (05)
