What is Turnitin?

Turnitin is an originality checking and plagiarism prevention service that checks your writing for citation mistakes or inappropriate copying. When you submit your paper, Turnitin compares it to text in its massive database of student work, websites, books, articles, etc.  

Turnitin is integrated into the Assignments in many SNU Canvas courses. This means that when you upload your paper to your course for grading, it will automatically be sent through Turnitin’s repository. The originality report that it generates will help identify possible instances of plagiarism.

How do I view Turnitin results for my submission?

Turnitin provides information on the originality of the text in your assignments as well as a similarity index, which rates your submission on how similar it is to existing works.

Turnitin can deliver these reports to you as soon as they are generated (usually takes a minimum of ten minutes, but it can take longer) or after a set date, depending on your instructor’s preferences.

Similarity Score Explained

Similarity Reports provide a summary of matching or highly similar text found in a submitted paper. When a Similarity Report is available for viewing, an icon will appear in the Similarity column of the Assignment Inbox. Similarity Reports that have not yet finished generating are represented by a grayed out icon in the Similarity column. Reports that are not available may not have generated yet, or assignment settings may be delaying the generation of the report. The similarity score makes you aware of any problem areas your paper; you can then use this as a tool to revise your work.

The color of the report icon indicates the similarity score of the paper, based on the amount of matching or similar text that was uncovered. The percentage range is 0% to 100% The possible similarity indices are:

  • Blue: No matching text
  • Green: One word to 24% matching text
  • Yellow: 25-49% matching text
  • Orange: 50-74% matching text
  • Red: 75-100% matching text
