If the fourth work is plagiarized, only one or two authors are excluded. Hownet detection is to compare your paper with the papers already included in Hownet database with some algorithm, so as to find out which parts of your paper are suspected of plagiarism.

After 20 13 upgraded to 5.0 system, HowNet's detection ability became more powerful. I still suggest writing it myself, and a few can learn from other articles.
