Plagiarism detection

Aarhus University uses Ouriginal (formerly Urkund) for the screening of exam assignments. The screening of texts is carried out in order to detect any plagiarism.

The primary use of Ouriginal is found in the digital exam systems Wiseflow and Digital exam. Ouriginal is integrated with this and checks all submitted material in these systems.

AU Library provides support in relation to the use of the system and is also a player in relation to the prevention of plagiarism at Aarhus University.

Ouriginal provides a quick guide on how to understand a Ouriginal report here

As a student, you cannot access Ouriginal for checking your own materials, as the system is not intended for this purpose.

Ouriginal support from AU Library

AU Library supports Ouriginal on weekdays within normal working hours (8.00-15.30). During holidays/holidays, please refer to Ouriginals own support to the extent that they are open.

As a teacher and examiner, you have access to external analyses via Wiseflow or Digital exam. Please contact us to find out what your options are if you have student exam assignments which are not checked in Ouriginal and via the exam systems.

We do not check scientific material in Ouriginal prior to submission to conferences or journals.

About Ouriginal

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 your local support in AU Library to learn more.

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.
