Plagiarism Checking Software for Rapid
Editorial Decision• Rapid editorial decision attracts good
researchers and improves journal’s quality(impact factor).
• Editorial turnaround time monitoring is important.
• Stategies not to waste time of editor andreviewer– Early statistical screening (Statistical Advisors)– Early usage of Plagiarism Checking DB (CrossCheck)Similariy Percentage•< 10% Low Percentage = Not Likely to Be an Issue (Disregard)– The similarity found in these papers is sporadic matching text or commonly used phrases.
– Single sources normally only yield 1-3% similarity. These reports may be disregarded.

•10-50% Moderate Percentage = Possible Issue (Review Briefly)– Papers that fall in this range may contain portions of copied text that areof some concern, but this depends on the percentage of similarity in theindividual sources. Opening and briefly reviewing these reports can ens
ure that no individual source has more than 10% similarity.

•> 50% High Percentage = Probable Issue (Review Carefully)– At this level, the report percentage is automatically highlighted by Cross
Check in orange.
– These reports require a more careful review. There is likely to be a highpercentage of similarity to one or more individual source.

Interpreting Matching Percentagesof Individual Sources•< 1%-3% match– Occurs with small groups of similar words or a few short phrases. In general,
there is little need to review these sources.

•4-7% match– These matches can be similar single sentences or a small paragraph. Onesource at this level may not be an issue, but several sources at this percentage
level could signify an overall problem with the submission.

•8-15% match– A source in this percentage range usually involves a few matching paragraphs. Similarity at this level could indicate improperly reused material.

•15-25% match– This level of similarity in a single source likely involves as much as one fullpage of matching material, depending on the size of the submission. It is
important to check matches carefully against the source.

•>25% match– This level of similarity from a single source should raise serious concerns
about inappropriate reuse, and should be checked very carefully.

Summary• CrossCheck (iThenticate) is now increasigly used in
KAMJE journals and seemed to useful to checkplagiarism and save the loss of editorial work
• We need careful review of the manuscript suspecting
plagiarism based on the similarity report.
• Although CrossCheck (iThenticate) is not complete, its
usage may prevent many cases of future plagiarism.
• Many Korean journals editors are encouraged to use
CrossCheck and include it in either journal website or“Instruction to Authors” to prevent plagiarism ethicalmisconduct.
