A group of Adelaide researchers has released an open-source tool that helps identify document authorship by comparing texts.
While their own test cases – and therefore the headlines – concentrated on identifying the authors of historical documents, it seems to The Register that any number of modern uses of such a tool might arise.
The two test cases the researchers drew on in developing their software, on Github here, were a series of US essays called The Federalist Papers, and the Letter to the Hebrews in the New Testament.
