Artificial intelligence explained: This article describes and explains the concepts and terminology behind what is today being termed as artificial intelligence. Further, it illustrates how these concepts relate to the field of project management, offering opportunity for better, more effective project planning and control. There are many definitions of artificial intelligence or AI. One of the funniest definitions I have run across is "AI is whatever hasn't been done yet" -- now there's a vague and unhelpful answer! One of the more useful definitions I have found is "AI is the ability of a computer program or a machine to think and learn. In general use, the term "artificial intelligence" means a machine which mimics human cognition."
