1, HowNet's duplicate checking method is different from other duplicate checking systems. Hownet duplicate checking is to submit word or pdf source files, which means that the format of the paper can be recognized. If the footnotes of the paper are quoted according to the standard format, the system can identify them and list them in the report. This part of the content will not be counted in the repetition rate of the text, but if there is a problem with the format, footnotes and endnotes that the system can't recognize will be regarded as duplicate checking.

2. Academic journal papers and graduation papers will have footnotes. Generally speaking, if the submitted paper is in word version and the footnotes are marked according to the format required by the school, in 90% cases, HowNet can correctly identify the footnotes and will not be marked as the text of the paper.

Generally, the marking position of footnotes is very important. Both sentences and quotation marks should be added before punctuation, so that this part of the content will not be marked red or yellow. Note, for reference only.

3. If the submitted papers are in pdf format, some HowNet cannot correctly identify the footnotes of most pdf files, and the contents of footnotes will be checked as the contents of the text and marked in red. However, with the gradual enhancement of HowNet's ability to identify pdf files, the duplicate checking system of HowNet in the future can also identify footnotes of pdf to prevent the unreasonable phenomenon that footnotes are marked red.
