Paper duplication check will detect the cover, original statement, abstract, keywords, text, notes and opening report of the paper, not just the repetition rate of the text. After the paper is uploaded to the duplicate checking system, the duplicate checking system will first carry out hierarchical processing, create fingerprints according to chapters, paragraphs, sentences and other levels, and also use the same technology to create fingerprint indexes for the comparative documents in the resource library. This hierarchical multi-level fingerprint structure can not only meet the rapid detection of long documents, but also meet the high requirements of the system for precision and recall because the minimum fingerprint granularity is sentences.

Paper duplicate checking includes text, original description, abstract, icon and formula description, references, appendices, experimental research results, conclusions, introduction, patents, documents, notes and various forms. During the graduation season, most colleges and universities will issue a notice explaining the specifications and duplicate checking instructions of the graduation thesis, and the school will uniformly issue the paper style and other contents, and generally explain the scope of duplicate checking in detail. If the school has specific requirements, it must be submitted according to the requirements of the school.
