Updated similarity score algorithm

Changes were made to Turnitin’s similarity score on 4 March 2021.

They include:

  • Better detection and exclusion accuracy of quotes
  • Better prioritization of internet sources (for example prioritizing a match wikipedia.com instead randomblog.com)
  • Better matching more content across our various databases

There’s more information on Turnitin’s support site, including information on existing submissions.
