Students they have submitted more than 22 million documents that may have been created by artificial intelligence in the past year, new data released by plagiarism detection firm Turnitin show.
A year ago, Turnitin released an AI writing detection tool that was trained on scores of student-written documents as well as other AI-generated texts.
Since then, more than 200 million documents have been examined by the crawler, mostly written by high school and college students.
Turnitin found that 11 percent may contain AI-generated text in 20 percent of their content, while 3 percent of the total documents examined appear to have 80 percent or more AI-generated text.
Turnitin reports that the detector it uses has a false positive rate of less than 1 percent when analyzing full documents.
Of course, all of the above could be a very good promotion of Turnitin's product.
