1. Because paper duplicate checking is divided into off-season and peak season, especially during graduation, basically colleges and universities will choose Zhejiang Library to duplicate check on HowNet, which leads to the need to duplicate a large number of papers in a short time, which is very time-consuming, resulting in slow duplicate check on HowNet.

2. It is related to the length of the paper. For example, the length of doctoral thesis is very long, and the detection time will be much longer than that of undergraduate thesis, so the slow detection of HowNet in Zhejiang Library will also be related to the number of words in the thesis itself.
