Professor Ashok Goel of Georgia Tech developed an artificially intelligent teaching assistant to help handle the enormous number of student questions in the online class, Knowledge-Based Artificial Intelligence. Professor Goel already had eight teaching assistants, but that wasn’t 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 ignored or confused and reach out with questions that go unanswered, their motivation to continue begins to taper off. Professor Goel decided to do something to improve this situation and his solution was to create a virtual assistant named Jill Watson.
Goel and his team developed several versions of Jill Watson before releasing her to the online forums. At first, the virtual assistant wasn’t 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 didn’t know she was a computer. The students, who were studying artificial intelligence, were interacting with the virtual assistant and couldn’t tell it apart from a real human being. Goel didn’t inform them about Jill’s true identity until April 26. The students were actually very positive about the experience.
The goal of Professor Goel’s virtual assistant next year is to take over answering 40% of all the questions posed by students on the online forum. Professor Goel has a much rosier outlook on the future of artificial intelligence.

Nicole Ihus’s son John Henry was born last month with a life-threatening disease. Nicole and her husband, who live in Kansas City, contacted doctors from Minnesota and Missouri in hopes of finding a doctor who could treat John Henry for the condition, but to no avail. Luckily, Nicole managed to get in contact with the “best doctor in the world for this condition” at Johns Hopkins All Children’s in St. Petersburg, Florida, so she traveled all the way to the Sunshine State to give her newborn son a fighting chance.
After John Henry was into the ICU, Nicole felt alone in the new state, although she knew that she had to leave her son’s side in order to buy him some new clothes. Upon ordering an Uber ride to the nearby Rhea Lana children’s clothing store, she was picked up by a woman named Belinda.
Shortly after Nicole got into Belinda’s car, the new mother couldn’t help talking about her heartbreaking circumstances.
“She told me her story,” Belinda said. “She was in tears a couple of times and I really felt for her.” Rather than simply dropping Nicole off at the store, however, Belinda parked the car and insisted on accompanying her passenger into the store so she could treat John Henry to new clothes. Needless to say, Nicole was filled with gratitude.
Nicole said, “For this stranger to go completely out of her way - stop what she was doing and stop making money- to come be with me for a couple of hours while we shopped together, that was just incredible.” As Nicole cares for her newborn son and raises money for his medical conditions, she hopes to introduce the Uber driver to her son as a thank you for her compassionate gesture.
