There is no exact value for the duplicate checking of Wanfang and HowNet, but generally speaking, the duplicate checking rate of Wanfang will be lower than HowNet. Wanfang is one of the three major providers of paper testing databases in China, and many colleges and universities use HowNet instead of Wanfang.

Relatively speaking, Wanfang's database is not as large, thorough and detailed as HowNet's database, and the duplicate checking results of different comparative databases in the system are also different. It is suggested that the system used in our school for duplicate checking of papers shall prevail.

The difference between Wanfang and HowNet

Compared with HowNet, the standard of Wanfang duplicate checking is too broad, because its database coverage is limited. When testing Wanfang, sometimes you will get 0% test results, while when testing HowNet with the same article, you will get 70%-80% repetition rate test results. Comparing their data sources is different.

It is also one of the main reasons for the great difference between the two test results. The contents of some papers are only of reference significance to HowNet duplicate checking, and Wanfang duplicate checking does not include English database. Once the article involves English, Wanfang can't use duplicate checking.

Comparatively speaking, Wanfang database is smaller than HowNet database, and the accuracy of duplicate checking rate is not enough, but Wanfang duplicate checking price is cheaper than HowNet, Wanfang is suitable for initial check, and HowNet is more suitable for final draft. The following is a detailed analysis of HowNet and Wanfang's database, detection entrance, document citation detection, repetition rate and chart similarity detection.
