"Cognitive computing systems learn and interact naturally with people to
extend what either humans or machine could do on their own. They help
human experts make better decisions by penetrating the complexity of Big
Data.
Cognitive computing systems get better over time as they build knowledge and
learn a domain - its language and terminology, its processes and its preferred
methods of interacting. "
