ORES aims to get around this by judging purely the content of an alteration. "The thing to note is it doesn't judge whether the facts that people are adding are actually true, because fact-checking is immensely difficult, it's looking at the quality," said Dr. John Carroll, a computational linguist at the University of Sussex.
"It should help a great deal with Wikipedia," he added.
Dr. Carroll own start-up, iLexir, provides software to automatically check the quality of written English in essays by foreign language students.
