Nowadays, many universities and publishing houses will use some professional duplicate checking software, such as Turnitin and iThenticate, to check the duplicates of papers submitted by students or researchers. These softwares can detect whether there are paragraphs or whole articles similar to other articles in the paper, and whether the citation format and document description format meet the requirements. Therefore, a good academic paper should pay attention to accurate and standardized citation when quoting other people's research results, and avoid directly copying the contents of other articles. Otherwise, it may be identified by duplicate checking software, resulting in serious academic misconduct.
It should be pointed out that duplicate checking software is not omnipotent, and there are also cases of misjudgment. Sometimes, some common words, formulas, quotations, etc. will appear in many articles, so they may also be misjudged as plagiarism. Therefore, the high similarity detected by the duplicate checking software will not have much impact if the papers follow academic norms and cite reasonably when using other people's achievements.
In short, when writing a paper, we should pay attention to the principles of academic integrity and standard citation to avoid copying and being identified by duplicate software. At the same time, we should also pay attention to the misjudgment of duplicate checking software and make reasonable explanations and explanations for some misjudged contents.
