As we all know, a paper consists of several parts. When writing a paper, looking for inspiration in the early stage, and designing a paper, we will refer to some materials and documents to explain your paper and check the duplicate, which is reflected here. Because a large number of papers and documents are cited, the references in the papers account for too many parts. At this time, it is necessary to check the duplicate.

Duplicate checking is to check the repetition rate of papers, and each paper detection system will have a relative comparison database. Duplicate checking is the process of matching in comparison database. Most paper detection systems are repetitive units in comparison sentences. When the paper repetition rate is the same, it will be bound as repetition.
