HowNet's duplicate checking is defined by the sentence paragraph repetition rate of 5%.

If the repetition rate of a sentence is higher than 5% in its paragraph, it needs to be further detected, and then whether it is plagiarized is judged by the number of words in the sentence. If 13 similar or identical words appear continuously, it is regarded as plagiarism. Titles and references are not involved in duplicate checking, but only if their formats meet the requirements.
