Wanfang detection system is a text similarity matching system based on Wanfang paper database resources, which uses collision fingerprint algorithm to compare the documents to be detected with the published documents in the database to find the content with similarity higher than the set threshold. However, China HowNet has adopted many techniques, including string comparison, wavelet analysis, TF-IDF algorithm and cosine similarity. The coverage and depth of the detected document library will also affect the accuracy of the detection results.
Generally speaking, although both systems are commonly used paper duplicate checking systems in China, their detection methods and database ranges are different, which may lead to some deviations in the detection results. Therefore, it is not easy to judge which system is more accurate, and it needs to be decided according to the specific situation. If more accurate test results are needed, it is suggested to combine your own judgment and multiple tests to draw more accurate conclusions.
