What resources does VeriCite use to identify possible plagiarism?
VeriCite compares student submissions against data that have been encrypted from millions of academically-related websites, both public and private, including books, journals, articles, open educational resources and much more. For example, the 4.6 million articles in the English edition of Wikipedia have been indexed and VeriCite is negotiating with commercial vendors to include their periodical and book databases in the process.
The VeriCite crawler was initiated with a “seed” list of several thousand key academic resources that are commonly plagiarized. The VeriCite crawler continuously indexes each of those sites and all the sites that are linked within those sites and beyond. Academically-related sites most often link to other academically oriented sites, and to sites that provide additional topical information for their site visitors (all potentially plagiarized material). We are constantly adding new sites to the list based on our crawling process, manual additions to the seed list, and negotiated permissions to add new resources.
In addition, each institution has their own private repository in which all student submissions for that institution are stored and used for comparison. VeriCite can even index papers from prior term courses in order to populate the private repository with several years worth of student work. All papers stored in this private repository remain the property of the institution and are removed from the VeriCite database if the institution discontinues the service.
