The Similarity Report provides an overall similarity breakdown for each submission to the iThenticate database. This breakdown determines the percentage of similarity between a submission and content existing in the database of the text comparison tool, iThenticate. The database includes billions of web pages (both current and archived content), a repository of work that has been submitted to Turnitin in the past, and a collection of documents, which comprises thousands of periodicals, journals, publications and CrossRef member content.

Interpreting the Similarity Report

iThenticate does not check for plagiarism in a submission. It checks a submission against the content database, and if there are instances where the submission’s content is similar to or matches against one or more sources, it will be flagged for review. It is perfectly natural for a submission to match against sources in the database. If the submission has used quotes and has referenced correctly, there will be instances where there will be a match. The similarity score simply makes the user aware of any problem areas in the submission.
