Watson's Creator Wants to Teach AI a New Trick: Common Sense

David Ferrucci, the man who built IBM's Jeopardy-playing machine, Watson, is explaining a children's story to his new creation. In the tale, Fernando and Zoey buy some plants. Fernando places his plant on a windowsill while Zoey tucks hers away in a darkened room. After a few days, Fernando's plant is green and healthy but the leaves of Zoey's have browned. She moves her plant to the windowsill, and it flourishes.
