Plagiarism is considered one of the most serious violations of research ethics and academic integrity. In scientific publishing, plagiarism occurs when a researcher copies words, ideas, figures, tables, methods, or results from another source without proper citation or acknowledgment. Plagiarism may occur intentionally or unintentionally; however, both forms can lead to severe academic, professional, ethical, and legal consequences. Scientific journals, universities, ethics committees, and international organizations strongly prohibit plagiarism because it damages scientific credibility, harms authorship rights, reduces trust in research, and may lead to retraction of published articles.
For this reason, checking plagiarism before manuscript submission has become an essential step in the research and publication process. Many journals routinely screen manuscripts using specialized plagiarism-detection software before peer review. If significant plagiarism is detected, the manuscript may be immediately rejected, the authors may be reported to their institutions, and future submissions may be restricted.
