Wanfang and Daya duplicate checking are two different paper duplicate checking systems, which have certain differences in database, algorithm and price.

1 database: Wanfang replica database is relatively small, with limited coverage, while Daya replica database is relatively large, containing more academic journals, dissertations and other resources. Therefore, the coverage of Daya duplicate checking is wider, and the detection result may be more accurate.

2 Algorithm: Wanfang duplicate checking uses advanced algorithm to detect text similarity, while Daya duplicate checking uses algorithm based on knowledge map to deeply analyze text semantics. Therefore, Daya duplicate checking algorithm is more advanced and can detect similarity more accurately.

3 Price: Wanfang has a relatively low check weight, which is suitable for some individuals or small organizations, while Daya has a relatively high check weight, but it can provide a more comprehensive paper similarity detection service.

In short, no matter which paper duplicate checking system you choose, you should take the duplicate checking results seriously and make necessary modifications and weight reduction to ensure the originality and legitimacy of the paper.
