Turnitin: Feedback Studio Originality Report and the Similarity Layer

Originality Reports provide a summary of matching or highly similar text found in a submitted paper. Turnitin checks against 45+ billion web pages, 337+ million student papers and 130+ million articles from academic books and publications.

The colour of the report icon indicates the Similarity Index 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

Direct source comparison

Direct Source Comparison allows a user to quickly compare matching text to the source in the Turnitin repository. Matches to other student papers are not available for Direct Source Comparison viewing unless the students’ are enrolled in your class. Direct Source Comparison can be accessed from the Match Overview or the All Sources view mode of the Originality Report.

Users can either view the Direct Source Comparison as a glimpse within the paper or as the Full Source Text within the sidebar. The glimpse only provides the matching text within context of a few outlying sentences from the source while the Full Source Text loads in the sidebar and contains the full text of the source and all the match instances.

  • To access a direct source comparison click on a highlighted area of text on the left hand (student paper) side

direct source.fw

  • A pop-up window will appear above the highlighted text displaying the matching text within the source of the match

  • To view the matching text within the full source text click on the ‘Full source text’ button 
  • The full source text will load into the sidebar
  • If there are multiple matches to this source, click on the arrow icons to quickly navigate through the match instances
  • To exit the ‘Full Source Text’ view click on the ‘X’ button
