First of all, the duplicate checking of HowNet does require the paper size, and it is generally not recommended to exceed 15m. Once it exceeds 15m, the file is too large to be submitted. At this time, HowNet suggested that you can delete the picture. Because HowNet has limited ability to identify papers at present, pictures are not the most important in paper search.

Secondly, we need to check whether the paper documents are too big because of the joint exam. Joint testing refers to testing several items together. However, what HowNet's checklist wants to tell you is that when HowNet checks the duplicate, don't test it together.

There are two reasons: first, we don't know whose repetition rate is after the test. Second, the repetition rate after joint measurement may be inaccurate. And joint testing may lead to system detection failure.

Finally, a reminder, except that the file is too large to submit. You can't submit if you exceed the word limit, and the word limit of different versions of HowNet is different.

The file format of 1. is incorrect: when the paper is copied on HowNet, the document format uploaded by the paper is generally the docx and doc format of Word, and pdf is not supported. Please do not upload files in other formats.

2. Error in file size: Word document size cannot exceed 15MB, otherwise it cannot be uploaded; Please delete unnecessary pictures (the system does not detect pictures).

3. System error: The last one is that a system error is detected and cannot be uploaded.
