Enhanced Similarity Report
Over similarity
The overall similarity is a percentage showing how much text from the submission matches to sources in our database. Turnitin calculate this percentage by dividing the number of matching words by the total number of words in the document.
The Report now provides two unique views for faster insights into instances of text similarity:
The Match Groups view divides the overall similarity into four categories based on the usage of in-text citation and quotation marks.
Not Cited or Quoted - The number of text matches that are not written as a quotation or has no citation to its original source.
Missing Quotations - This text is cited, but the match is so exact that it may also require quotation marks.
Missing Citation - This text is written as a quote, but lacks a citation to its original source.
Cited and Quoted - This text contains a quotation and is cited to a source. You may want to review them for your preferred formatting.Source number
Each highlight in the document has a source number appended to it, which is indicated in the top row of its corresponding source card. Selecting a highlight in the document will bring its corresponding source card into focus in the right-side panel.
Viewing Matches with Source Cards
Source cards contain details about the highlighted match and its source material. Expand a source card for more options.
The top row indicates the top matching source ranking number (this number also appears next to the corresponding highlighted match in the document), the database type, and the match group criteria.
The second row contains the name of the top matching source and the percentage matched with the document.
The third row indicates the number of matching text blocks to that source and match group, as well as a total word count for all matches with the same criteria.
Exploring a source card
To view the source's full url, along with more actions, expand the source card by selecting either:
- A highlighted match in the document,
- or a source card in the right-side panel
Sources provides a list of sources organized in descending order by highest total similarity percentage. (These sources are the same as those detailed in source cards in the Match Groups view.)
What are overlapping sources?
It is possible that similar text can be found within multiple sources. When text is similar to more than one source, whichever source has the most matched words will display first. When multiple sources are found matching the same exact words, the report will prioritize sources as best match, or top source, in this order:
- Internet
- Publications
- Submitted Works (student papers)
To reveal overlapping sources matched to the same text, choose the submission highlight or source card with the match in question, then select View other sources at the bottom of the card in the right-side panel:
Show overlapping sources list
Select the Show overlapping sources option at the top of the Source list. Selecting a source card will highlight the matching text in the submission.
