This check prevents plagiarised manuscripts from proceeding to review.
AIRA uses an external service (iThenticate, powered by Crossref) to check for text-overlap in all manuscript submissions. The manuscript will not be sent to review if the text-overlap percentage is too high. The authors will be asked to make appropriate revisions to proceed with the review. Sometimes there is a small amount of text-overlap with previous publications. Then, the editorial office works with the authors to make revisions during the manuscript review.
You do not need to take action if this check highlights text overlap. The editorial office is always aware and will ensure the text overlap is addressed during author revisions. The editorial office will also check the manuscript again in iThenticate prior to acceptance.
