Is it plagiarism if you submit your own work again?
Self-plagiarism means reusing work that you have already published or submitted for a class. It can involve re-submitting an entire paper, copying or paraphrasing passages from your previous work, or recycling old data. Self-plagiarism misleads your readers by presenting old work as completely new and original.
How much of a paper can be plagiarized?
There is a lack of consensus or clear-cut-rules on what percentage of plagiarism is acceptable in a manuscript. Going by the convention, usually a text similarity below 15% is acceptable by the journals and a similarity of >25% is considered as high percentage of plagiarism.
