Information for supervisors

The Similarity Report is a dynamic document that offers a synopsis of text matches found in submitted work when compared to an extensive database of online sources, academic publications, and previously submitted documents. This tool enables PhD students and instructors to examine similarities between the submitted work and online materials. The percentage presented in a student's submission, referred to as the similarity index or similarity score, indicates the extent to which their work matches content from the database. However, this percentage should not be taken as a definitive indicator of plagiarism. The report may show matches to correctly cited and appropriately used sources, making it imperative for the instructor to apply their academic judgment in evaluating these matches. 

The report icon's colours can be adjusted, to allow for easier reading of the paper's similarity score, determined by the extent of matching or similar text found. The score ranges from 0% to 100%. The allocated colours do not have to match the colours that are decided upon by the faculty, as users can apply their colour schemes individually. Facilitate easy reading by applying colours to categories, for example:

  • Blue: No matching text
  • Green: 1-24% matching text
  • Yellow: 25-49% matching text
  • Orange: 50-74% matching text
  • Red: 75-100% matching text

The report can show high matches that stem from quotes, references or previously uploaded documents. To exclude such matches in the report,  advanced settings can be applied.

It is important to note that iThenticate will show a high percentage of matching text when the student has previously uploaded their work to the database. This can be addressed by applying advanced settings, such as excluding specific sources or excluding by word number.
