Subject-matter expert Turing test

A subject-matter expert Turing Test is when a computer program attempts to have a conversation with a person to determine if it's a computer or a real person answering it. It can be tricky for a computer to pass the test since it needs to know a lot about a certain subject and be able to answer questions about it correctly. If the person can't guess that the answers are from a computer, the computer has passed the Turing test!
