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. This online course is a core requirement of Georgia Tech's online Master of Science in Computer Science program. 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 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 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. 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.
单选题
What do we learn about Knowledge-Based Artificial Intelligence? ______
单选题
How did the students feel about Jill Watson? ______
【正确答案】
D
【答案解析】由题干中的students feel about Jill Watson定位到第三段最后三句。 推理判断题。定位句指出,学习人工智能的学生与虚拟助理进行互动,而且无法将其与真人区分开来,故答案为D。 文中未提及A“他们认为她有点太假了”、B“他们发现她不如预期的那么有能力”和C“他们不得不钦佩她的知识”,故排除。
单选题
What does Professor Goel plan to do next with Jill Watson? ______
【正确答案】
C
【答案解析】由题干中的Professor Goel plan to do定位到最后一段第一句。 推理判断题。定位句指出,戈埃尔教授的虚拟助教明年的目标是回答在线论坛里学生提出的40%的问题。由此可见,戈埃尔教授会让虚拟助教回答更多的学生问题,故答案为C。 最后一段第二句指出,吉尔·沃森会在下个学期换个别的名字,而非发布不同的版本,故排除A项。文中并未提及B“给她新的问题和答案”和D“鼓励学生更自由地与她互动”,故排除。
