HowNet will look up English documents. At present, HowNet contains a lot of English documents, and has the function of translation between Chinese and English, which can detect the repetition rate of English papers. Turnitin is a more authoritative duplicate checking system for English papers.

When quoting English documents, we should pay attention to avoid copying and pasting directly, but should rewrite them appropriately to reduce the risk detected by the duplicate checking system. At the same time, it is necessary to standardize the citation format to ensure the correct citation and labeling of cited documents.
