Plagiarism is not allowed in IEEE papers, and even a small amount of plagiarism can result in rejection of the paper or other disciplinary actions. IEEE (Institute of Electrical and Electronics Engineers) has strict guidelines regarding plagiarism and expects authors to adhere to high standards of academic integrity.
IEEE uses a tool called CrossCheck to detect plagiarism, and papers found to have significant similarities to previously published work, even if it’s the author’s own work, will not be accepted. In general, it is recommended that authors aim for less than 20% similarity in their papers, although ultimately it is up to the discretion of the editors and reviewers to determine what constitutes plagiarism and how much similarity is acceptable.
It’s important to note that even unintentional plagiarism, such as failing to properly cite sources or paraphrasing too closely, can result in accusations of academic misconduct. To avoid any issues, it’s important to thoroughly cite all sources and ensure that your paper is original and adds new contributions to the field.
