First of all, it is possible to contribute to the same journal again after reviewing the rejection. The main purpose of duplicate checking system is to ensure the quality and originality of academic research, not to punish researchers. Therefore, after the paper is checked and rejected, the author can modify and improve the paper to further improve the quality of the paper and resubmit it to the same journal. Of course, the result of re-submission will depend on whether the revised paper meets the requirements and level of the journal.

Secondly, we need to consider whether there are any restrictions. Different journals may have different submission rules after reviewing and rejecting manuscripts. Some journals may clearly stipulate that the same paper will no longer be employed after being rejected, while some journals may adopt a more flexible attitude and allow authors to submit again after revision. Therefore, the author needs to carefully read the journal's submission guide or consult the editorial department to understand the journal's review and rejection policy.

In addition, the scope of revision of the paper also needs to be considered. If only part of the paper is highly similar by the duplicate checking system, and other aspects meet the requirements of the journal, then the author can modify the problems pointed out by the duplicate checking system and resubmit the paper. However, if there is serious plagiarism or plagiarism in the paper, even if the author makes changes, it may not be able to submit it to the same journal again.

Finally, the author should pay attention to abide by academic ethics when revising and resubmitting. Even if the paper is found to be highly similar by the duplicate checking system, the author needs to ensure that the revised paper is independent and original, and there is no plagiarism or plagiarism. Otherwise, not only can you not contribute to the same journal again, but you may also face accusations of academic misconduct.
