Turnitin (stylized as turnitin) is an Internet-based similarity detection service run by the American company Turnitin, LLC, a subsidiary of Advance Publications. Founded in 1998, it sells its licenses to universities and high schools who then use the software as a service (SaaS) website to check submitted documents against its database and the ...
A study was conducted to test the effectiveness of similarity detection software in a higher education setting. One part of the study assigned one group of students to write a paper. These students were first educated about plagiarism and informed that their work was to be run through a content similarity detection system.
At off-peak hours for Turnitin, they could run full reports of every single article on English Wikipedia. The reports would detail which parts of Wikipedia articles matched web content, proprietary content, and, if desired, prior submissions to Turnitin. The reports would identify which external source positively overlapped for each match.

The Turnitin trial, should it be approved by the community will have certain questions it seeks to answer: Does Turnitin's system effectively screen out false positives created by Wikipedia mirrors or sites that legitimately reuse our content under a compatible license?

One formal definition is that it is "a summary of the evidence contained in an examinee's responses to the items of a test that are related to the construct or constructs being measured."
If Turnitin does find matches, investigation and confirmation is still necessary. The question is whether having Turnitin's reports gives us another beneficial tool and improves upon our current copyright checking regime. We can test to see if it does, and if it does, then a partial solution is better than a no solution.
