Similarity check (Unicheck - previously Turnitin)

If you are a WUR staff member or PhD candidate and you do not have access to Brightspace, you can ask the Copyright Information Point to perform a similarity check.

How to request a similarity check

Send us your document by e-mail and we will use Unicheck to perform the check. Previously, we used Turnitin. The outcome of the check will be sent to you as soon as possible. Teachers are requested to use Unicheck in Brightspace to check student work, for example, by creating a Brightspace Course for MSc-thesis students where students can submit their thesis.

Check for similarity

Unicheck compares the text of the submitted document with our Institutional Library as well as with open access sources on the internet. Our Institutional Library consists of over 285,000 documents that have been uploaded by WUR staff and students to the Turnitin repository since 2009.  

Unicheck doesn't have a global database consisting of all Institutional Libraries. Therefore, it is not possible to compare documents against documents uploaded by other institutions. As you may have read on the intranet on the Brightspace & external learning tools group page from ESA: “During the implementation process of Unicheck, it was discovered that Unicheck only checks against open sources whereas Turnitin also checked against password protected sources (e.g. licensed journals). The Brightspace team considers this a very high priority and is in close contact with Unicheck to solve this issue hopefully as soon as possible.” 

Unicheck PDF report

After the similarity check, the Unicheck PDF report will be mailed to you and if necessary, an information specialist from the Copyright Information Point will explain how to interpret your report.

Here is some information on how to interpret the Unicheck PDF report:

  • Page 1 of the PDF report lists the total match score (similarity score). It is the total percentage of matching text. This total score is then broken down into a percentage for internet sources and a percentage for library sources from the Institutional Library.The source with the highest match is also provided. The percentage of quotes (in-text citations) is indicated if detected and the exclusion setting is on. If character replacements are used, it will be listed here as well. An example of a replacement is when a Latin o is replaced by a Cyrillic o. At the end of the PDF report, all sources are listed. 
  • Page 2 of the PDF report start showing the original document and Unicheck's findings. Detected matches are highlighted in orange, quotes or in-text citations in blue, and references in purple. At the bottom of each page, matching sources are numbered. The numbers correspond to the sources given at the end of the PDF report.
