The Akron professor says he has run additional tests on the data since the first study and found nothing to contradict the original findings. “I’m not going to read anything Les Perelman ever writes,” he told The Chronicle. Shermis, a psychology professor, says he has not read the critique. Shermis and his fellow researchers to task in a blistering critique, accusing them of bad data analysis and suggesting a retraction. They concluded that the robots awarded scores that were reliably similar to those given by humans on the same essays. Shermis and his colleagues analyzed 22,000 essays from high-school and junior-high students that had been scored by both humans and software programs from nine major testing companies. Shermis, a former dean of the College of Education at the University of Akron. In recent years, the target of his criticism has been Mark D. Although he retired from MIT in 2012, he persists as a thorn in the side of testing companies and their advocates. He speaks in a deliberate, husky baritone, almost devoid of inflection, which makes him sound perpetually weary.īut this effect belies his appetite for the fight. He wears glasses and hearing aids, and his mustache is graying. Perelman, 66, does not look like a crusader. “How can these people claim that they are grading human communication?” Challenging Evidence Perelman sits back in his chair, victorious. Immediately the score appears on the screen: 5.4 points out of 6, with “advanced” ratings for “focus and meaning” and “language use and style.” He pastes the nonsense essay into the answer field and clicks “submit.” Perelman copies the nonsensical text of the “privateness” essay and opens MY Access!, an online writing-instruction product that uses the same essay-scoring technology that the Graduate Management Admission Test employs as a second reader.

Perelman criticizing the automatons by appealing to his audience’s sense of irony.īy that measure, the Babel Generator is a triumph, turning the concept of automation into a farce: machines fooling machines for the amusement of human skeptics. Until now, his fight against essay-grading software has followed the classic man-versus-machine trope, with Mr. He has spent the past decade finding new ways to make that point, and the Babel Generator is arguably his cleverest stunt to date. More to the point, they cannot tell gibberish from lucid writing. Perelman’s fundamental problem with essay-grading automatons, he explains, is that they “are not measuring any of the real constructs that have to do with writing.” They cannot read meaning, and they cannot check facts. In 2012 he published an essay that employed an obscenity (used as a technical term) 46 times, including in the title. Perelman says the rubric is so rigid, and time so short, that they may as well be robots.) (That test is graded by human readers, but Mr. (It’s a skill he happily demonstrated to a New York Times reporter in 2005.) In presentations, he likes to show how the Gettysburg Address would have scored poorly on the SAT writing test. He has claimed to be able to guess, from across a room, the scores awarded to SAT essays, judging solely on the basis of length. SoftwareĬritics of automated essay scoring are a small but lively band, and Mr. Perelman is not trying to impress humans. Perelman has entered only one keyword: “privacy.” With the click of a button, the program produced a string of bloated sentences that, though grammatically correct and structurally sound, have no coherent meaning. Perelman built with a team of students from MIT and Harvard University, can generate essays from scratch using as many as three keywords.įor this essay, Mr. Essay Language Generator, or Babel, a new piece of weaponry in his continuing war on automated essay-grading software. Perelman wrote the essay in less than one second, using the Basic Automatic B.S. “Humankind will always subjugate privateness.” “Privateness has not been and undoubtedly never will be lauded, precarious, and decent,” he reads.
