First, most schools choose to check the duplication of the knowledge network, and students may choose other systems when checking in advance. The first draft of the paper must be a paper duplicate checking system with relatively low price. But we must choose some safe and reliable paper duplicate checking systems. Although HowNet duplicate checking is not open to individuals, there are many illegal enterprises posing as academic misconduct duplicate checking, and the test results are naturally different.

Secondly, the types of paper detection are analyzed, and academic misconduct is divided into several types of repeated detection. According to different detection types, there are unique databases, and the results are naturally different.

Thirdly, whether the uploaded content changes and whether the paper form is different will affect the inconsistency of the paper inspection report. According to the actual situation, specific problems are analyzed. Moreover, the database is updated in real time, so it is not too early to check the duplicate in advance. If it is too early, there may be new papers included, which may provide you with reference materials. In addition, the school has its own library, which is unknown to the outside world and confidential private documents are not made public, so the external paper detection system cannot call these resources.

Therefore, it is necessary to analyze specific problems. Due to different situations, each paper duplicate checking system will generate different "detection" reports. Therefore, a specific case study is needed, and then at the end of the paper, the duplicate checking rate is reduced to below the requirements of the school, just in case.
