2. Image or chart similarity: Identify potential improper use by assessing the similarity between images or charts.
3. Reference citation: Determine whether there is improper use, plagiarism, misuse, or lack of citation in references.

What Percentage of Plagiarism is Considered Plagiarism?

Generally, a plagiarism rate exceeding 30% can be considered plagiarism, but the specific criteria may vary depending on the content of the article, the tools used, and the requirements of the institution.
