Artificial Intelligence Helps in Detecting Cheating in Class Assignments

Artificial Intelligence can help determine whether an assignment was written by its author or a ghost writer. 
The study was done by researchers at Department of Computer Science at University of Copenhagen based on an analysis of 130,000 Danish assignments. They were able to detect with 90% accuracy whether the assignment was written by its author or by a ghost writer. It is common knowledge that Danish high school students use online services to prepare assignments but the Lectio platform used to check plagiarism cannot detect it. The program Ghostwriter developed by researchers use big data and artificial intelligence and looks at the writing pattern of the students based on previously submitted assignments to reach a conclusion. 
The AI application may find applications beyond the academic world and in Police Department where forged documents can be detect. The program uses a Siamese neural network to distinguish writing styles of two texts. https://www.science.ku.dk/english/press/news/2019/tempted-to-cheat-on-a-written-exam-artificial-intelligence-is-90-percent-certain-to-nab-you/
