Plagiarism Screening

Plagiarism Policy

J-KOMA defines plagiarism as the use of others’ ideas, words, data, or works without proper citation, including but not limited to:

• Direct copying of text without quotation marks and references.
• Paraphrasing without acknowledging the original source.
• Self-plagiarism (reusing one’s own work without acknowledgment).
• Plagiarism of ideas or data without credit.

Plagiarism in any form is not tolerated and may result in manuscript rejection or further sanctions.

Plagiarism Screening Process

Stage: Each manuscript is screened using software such as Turnitin or iThenticate before the peer review process.

Threshold: Similarity below 15% is considered safe; 15–25% is subject to evaluation; above 25% is typically rejected.

Additional Check: Editors manually review images, tables, and datasets for originality.

Violation Consequences

• Manuscript rejection without review.
• Retraction of published articles.
• Submission ban for 3–5 years.
• Notification to the author’s institution.

Tips to Avoid Plagiarism

• Use citations according to the IEEE style.
• Paraphrase using your own words and provide proper references.
• Check your manuscript using tools like Turnitin before submission.
• Learn publication ethics from COPE or UNJ writing workshops.
