Generally speaking, the detection algorithm of PaperPass is strict, but sometimes it may lead to misjudgment. The duplicate checking system of HowNet is more scientific, and the updating speed is fast, with an algorithm threshold of 3%. In terms of color coding, PaperPass marks plagiarized content as red, lightly plagiarized content as yellow, HowNet marks plagiarized content as red and quoted content as yellow. In addition, there are huge differences between the two databases, and HowNet is the largest detection system in domestic databases.
Therefore, the detection of HowNet is more stringent.
