Turnitin's product: Authorship Investigation

The Telegraph talks about "contract cheating," related to students paying third parties to perform
course work, which amounts to a form of plagiarism:



Amid growing concern over “contract cheating”, Turnitin, the largest provider of monitoring software to British universities, will launch a new programme designed to catch out students who pay for professionally written essays.

The new software, named Authorship Investigation, will monitor and learn the writing styles of individual students and flag up content which shows considerable divergence from their previous work.
