Omitting information when submitting a paper may have serious consequences. First of all, the omission of key information may lead to the direct rejection of the paper. Many journals and conferences will make a preliminary screening after receiving the manuscript. If they find that they lack necessary information, such as the author's contact information, abstract of the paper, keywords, etc. They may reject the manuscript directly.

Secondly, the omission of information may affect the evaluation process of the paper. Reviewers need enough information to evaluate the quality and relevance of papers. Without this information, reviewers may not fully understand the content and contribution of the paper, thus affecting their evaluation results. This may lead to delayed acceptance or rejection of the paper, or require the author to provide more explanations and supplementary materials.

In addition, the lack of information may also affect the citation and dissemination of papers. If the paper lacks the author's contact information, other researchers may not be able to contact the author for more information or cooperation. Similarly, if the paper lacks keywords or abstracts, other researchers may not be able to accurately understand the theme and content of the paper, thus affecting its citation and dissemination.

Finally, the omission of information may also lead to accusations of academic misconduct. Some journals and conferences require authors to provide detailed information about data sources, experimental methods and interpretation of results. If the author omits this information, he may be suspected of academic misconduct, such as data fraud or plagiarism. This will seriously affect the author's academic reputation and career development.

Therefore, in order to avoid these consequences, authors should carefully read the submission guide of journals or conferences and ensure that all necessary information is provided. At the same time, the author can also ask peers or tutors to help review the submission to ensure that no important information is missed.
