Both Daya and Victoria census are commonly used duplicate checking tools for papers, but their duplicate checking standards and algorithms are different, so it is impossible to simply compare which one has a higher duplicate checking rate.

Daya duplicate checking mainly uses sentences as the smallest unit to check duplicates, which can detect some minor duplicates, but its database is relatively small, and there may be some missing cases. The dimension census takes paragraphs as the smallest unit to check duplicates, paying more attention to the repetition rate of the whole content, and the database is larger, which can detect more duplicate content.

Therefore, when choosing a duplicate checking tool, you need to choose it according to your own needs and paper type. At the same time, it is suggested to use a variety of duplicate checking tools to test the final version to ensure the accuracy and reliability of the duplicate checking results. HowNet and VIP are systems used by most schools, and their databases are authoritative. Paperfree and papertime are auxiliary revision references, which provide free weight checking, machine weight reduction, online revision and other functions, covering about 70% of the data of HowNet, which can reduce the absolute cost of the previous inspection fee.
