Similarity Screening

All manuscripts under review or published in Kirkuk University Journal for Agricultural Sciences (KUJAS) may be screened using similarity-checking software (e.g., Turnitin) to support the editorial assessment of originality.

KUJAS may run similarity screening at submission, during peer review, and post-publication when concerns arise.

CrossCheck (Crossref Similarity Check)

Unacceptable Practices

Plagiarism and unethical publishing behaviors include (but are not limited to):

• Plagiarism: using another person’s text, ideas, data, or figures without proper attribution.
• Self-plagiarism / redundant publication: substantial reuse of one’s own published text or results without transparent citation and justification.
• Duplicate publication: publishing the same or substantially similar work more than once without full disclosure.
• Simultaneous submission: submitting the same manuscript to more than one journal at the same time.
• Data fabrication or falsification: inventing data, manipulating results, or omitting data in a misleading way.
• Improper authorship credit: including authors who did not contribute substantially or excluding those who did.

How KUJAS Evaluates Similarity

The similarity report shows the percentage of text overlap between the submitted manuscript and existing sources. A high similarity percentage does not necessarily indicate plagiarism, and a low percentage does not guarantee originality.

• Overlap may arise from correctly cited quotations, standard methods language, or reference lists.
• The same percentage can reflect one large overlap source or many small overlaps.
• Figures and equations may not be fully evaluated by similarity tools.
