The duplicate checking rate of papers written by AI is relatively high, which is determined by the characteristics of its creative mode and language model. AI will refer to a large number of documents and existing papers when creating, so it has a high degree of similarity with other articles. In addition, the language model of AI is trained through the existing corpus, which also increases the possibility that it is similar to other articles. Moreover, the writing and expression of AI may be different from that of human beings, which will also lead to higher duplicate checking results. However, although the duplicate checking rate of AI writing is relatively high, it does not mean that all articles generated by AI are plagiarized or plagiarized. When writing with AI, you still need to check and revise carefully to ensure the originality and uniqueness of the article. At the same time, some duplicate checking tools can also be used to help detect and eliminate potential problems.
