Plagiarism detection

Aarhus University has 2 plagiarism detection systems, iThenticate and Ouriginal (formerly Urkund).  

Ouriginal is primarily used in conjunction with the digital exam systems Wiseflow and Digital Exam.  Ouriginal is integrated into these systems, thus all material submitted to Wiseflow and Digital Exam is checked by Urkund.

Ouriginal is a system for detecting plagiarism in student assignments at AU. AU Library fulfills the role of the University’s primary support for Ouriginal users. AU Library has solid experience using the system. They provide support for system use, and are also a key player in relation to the prevention of plagiarism at Aarhus University

iThenticate is used by Health and Science & Technology to detect plagiarism in PhD theses.  

Access to Ouriginal and iThenticate cannot be granted as a means of checking one’s own material, as the system’s structure is not designed in a way that makes it suitable for such a purpose. Such use would also place an undue focus on the system and what it can and cannot do, rather than on it’s core purpose which is to manage and promote good practice in citing, paraphrasing, etc.   

Questions about Ouriginal (formerly Urkund)?

If you have question about Ouriginal, please contact, or your local faculty representative.   

We support Ouriginal on weekdays within normal working hours (8.00-15.30). During holidays / holidays we refer to Ouriginal's own support to the extent that they are open (this is stated via the Ouriginal website and our mail-reply).

What is Ouriginal?

Ouriginal is a plagiarism detection tool, accessible to all lecturers at Aarhus University via the Digital Exam systems.

Ouriginal can detect overlaps between texts and thus help to spot cheating in written assignments. Ouriginal searches in 3 different sources: the Internet, material from publishers and previously screened tasks from institutions with a license to the system.  

Please note that Ouriginal does not work in conjunction with all the publishers that AU Library provides access to. See a list on Ouriginal's own website. The list is not exhaustive. Please contact your faculty representative if you have any questions about specific publishers, or if you have suggestions for journals that you would like to see included in Ouriginal's comparison base. We will then contact Ouriginal in order to discover what possibilities are available to meet your needs.

How do I use Ouriginal?

  1. Ouriginal is mostly employed in relation to the digital exam systems, where tasks are screened automatically. Ouriginal is integrated into Wiseflow and Digital Exam. 

  1. Ouriginal can also be used on an ad hoc basis in special cases. Contact our support to learn more: or contact your local faculty representative.

Manuals and guides to Ouriginal

If I suspect plagiarism

If you suspect plagiarism in an assignment, it is important that you do not consider the Ouriginal analysis to be concrete proof the student has committed plagiarism.  

Ouriginal highlights only duplicate text areas between documents, and duplicate text does not necessarily equal plagiarism. Duplicate text may, for example, be a quote that has been viably inserted into a task and where a clear source has been documented. An Ouriginal analysis must be read in its context in order to determine whether any plagiarism has occurred.  

The Ouriginal analysis must be studied with a view to determining whether it is just a matter of careless citation practice or plagiarism. If you need help finding out how to read an Ouriginal analysis, AU Library Ouriginal Support are there to assist you. 

If, after having studied an Ouriginal analysis thoroughly, you have decided to proceed with a case, you must report and document the case to Educational Law. Educational Law will handle the subsequent processing of the case, based on your documentation.
