Paper duplicate inspection is usually carried out by a professional paper duplicate inspection system. These duplicate checking systems will collect a large number of literature resources and develop corresponding duplicate checking algorithms. In duplicate checking, the system compares the paper with the resources in the database according to a certain algorithm, identifies the duplicate content, and calculates the repetition of the whole article.

In general, the duplicate checking system will automatically identify all parts of the paper according to the format of the paper, such as abstract, text, conclusion and so on. , and classify these parts for repeated inspection. The system will compare the words in the paper with the documents in the database sentence by sentence. If a character or sentence that repeats continuously is found, it is judged as repeated content, and the corresponding repetition rate is calculated.

In addition to using the duplicate checking system, you can also check by yourself in other ways, such as using a search engine to search the key sentences in the paper to see if there are similar results. However, it should be noted that self-examination can only be used as an auxiliary means, and the final result of duplicate checking still needs to be subject to the regulations of the school or periodical.

When checking duplicate papers, we should choose a formal and reliable duplicate checking system to avoid paper leakage or other risks caused by using unsafe duplicate checking tools. At the same time, we should check the duplicate according to the requirements of schools or periodicals, abide by academic norms and moral standards, and ensure the originality and academic quality of the papers.
