Generally speaking, if there is a lot of plagiarism or plagiarism in the paper, the detection result of HowNet is usually higher than that of PaperPass and Wanfang. This is because HowNet has a more comprehensive academic database and a stricter detection algorithm, which can more accurately detect similar contents and irregular citation formats in papers.
As for which duplicate checking tool is closer to the result of the school knowledge network test, it needs to be decided according to the specific situation. If the school uses the hownet detection system, then the detection result of the system is the closest to the school. If the school uses other detection systems, such as Wanfang or PaperPass, it needs to be compared and evaluated according to the specific situation.
To sum up, in order to get accurate duplicate checking results, it is suggested to directly use duplicate checking tools designated by schools or institutions for testing, so as to better understand the gap between your papers and the requirements of schools.
