This online course is a core requirement of Georgia Techs online Master of Science in Computer Science program. Professor Goel already had eight teaching assistants, but that wasnt enough to deal with the overwhelming number of daily questions from students.Many students drop out of online courses because of the lack of teaching support. When students feel isolated or confused and reach out with questions that go unanswered, their motivation to continue begins to fade. Professor Goel decided to do something to remedy this situation and his solution was to create a virtual assistant named Jill Watson, which is based on the IBM Watson platform.Goel and his team developed several versions of Jill Watson before releasing her to the online forums. At first, the virtual assistant wasnt too great. But Goel and his team sourced the online discussion forum to find all the 40,000 questions that had ever been asked since the class was launched. Then they began to feed Jill with the questions and answers. After some adjustments and sufficient time, Jill was able to answer the students questions correctly 97% of the time. The virtual assistant became so advanced and realistic that the students didnt know she was a computer. The students, who were studying artificial intelligence, were interacting with the virtual assistant and couldnt tell it apart from a real human being. Goel didnt inform them about Jills true identity until April 26. The students were actually very positive about the experience.The goal of Professor Goels virtual assistant next year is to take over answering 40% of all the questions posed by students on the online forum. The name Jill Watson will, of course, change to something else next semester. Professor Goel has a much rosier outlook on the future of artificial intelligence than, say, Elon Musk, Stephen Hawking, Bill Gates or Steve Wozniak.46.
