1. Provide evidence: If you can prove that your paper is original, then you can successfully appeal. This may include your drafts, research notes, reference materials, etc. You can also provide evidence to prove that you have discussed this problem with others and that you have no intention of plagiarism.
2. Explain misunderstanding: Sometimes, the accusation of plagiarism may be a misunderstanding or a false alarm. For example, your paper may have a similar point of view or structure to another paper, but it doesn't mean that you copied it. In this case, you need to explain how this similarity came about, and prove that your thesis was completed independently.
3. Ask for re-evaluation: If you think the accusation of plagiarism is wrong, you can ask for re-evaluation of your paper. This may require you to provide more evidence, or ask a third party to make an evaluation.
4. Submit a formal complaint: If your school or publisher has a formal complaint procedure, you should follow this procedure. This usually requires you to fill out a form detailing your situation and attach all relevant evidence.
5. Seek legal help: If your paper is wrongly accused of plagiarism, you have tried all other methods but still can't solve the problem, you may need to seek legal help. You can contact a lawyer to see if there is enough evidence to file a lawsuit.
Generally speaking, if your paper is accused of plagiarism, you should take action as soon as possible. You should collect all relevant evidence and submit a complaint as soon as possible. At the same time, you should keep calm and professional, so that you can solve this problem effectively.
