Per TFA, "98% accuracy rate" is advertised by Turnitin. They don't say what they mean by that, but if that's the specificity, then that means a class of 300 with no cheaters would have 6 false-positives on each assignment, making it not particularly useful for catching individual cheaters. OTOH if it really is 98% accurate and you get 100 positives on an assignment, you can probably figure there is systemic cheating going on.
