What about pattern recognition? Years ago neural nets were the great hope for identifying patterns in data which were not detected by human analysts. Perhaps Watson could help to identify patterns of crime in urban environments to enable preventative steps to be taken. It would be a fitting application honoring his namesake.
Good to see the clone version of Watson being used in different fields. Definitely applications of watson can truly revolutionize the way we deal with data because watson can process lot of data very quickly.
