Tempted to cheat on a written exam? Artificial intelligence is 90% certain to nab you

Combining big data with artificial intelligence has allowed University of Copenhagen researchers to determine whether you wrote your assignment or whether a ghostwriter penned it for you--with nearly 90 percent accuracy. Several studies have shown that cheating on assignments is widespread and becoming increasingly prevalent among high school students. At the University of Copenhagen's Department of Computer Science, efforts to detect cheating on assignments through writing analysis by way of artificial intelligence have been underway for a few years. Now, based on analyses of 130,000 written Danish assignments, scientists can, with nearly 90 percent accuracy, detect whether a student has written an assignment on their own or if a ghostwriter composed it. Danish high schools currently use the Lectio platform to check if a student has handed in plagiarized work with passages copied directly from a previously submitted assignment.
