The following material was taken from the Turn-It-In website:
"Every paper submitted is returned in the form of a customized Originality Report. Results are based on exhaustive searches of billions of pages from both current and archived instances of the internet, millions of student papers previously submitted to Turnitin, and commercial databases of journal articles and periodicals."
"The industry's most advanced search technology that checks papers against our in-house copies of both current and archived internet content and our proprietary database of millions of previously submitted student papers."
'Any matches uncovered between submitted papers and source material is detailed in an intuitive and unambiguous format..."
Here is an example of an excerpt from a Turn-It-In report:
Note that the words in purple on the left were taken from the student's paper, while the words on the right were found in an online source; Turn-It-In identified the words in the student's paper that were copied (without attribution) from the web.
Question (True/False): Turn-It-In is very effective in detecting plagiarism.
