Firstly, the fuzzy algorithm is applied to the paper duplicate checking system. When changing and reducing the weight of paper, try not to disturb the outline structure of paper and modify the parts with high repetition rate. Because if the outline structure is disturbed, the system may recognize it as another piece of paper, and the position of the mark color will be different.

Second, the sensitivity of the universal duplicate inspection system is set to a sensitivity threshold of 5%. If it is higher than this threshold, it will be detected as plagiarism. Therefore, when studying literature, you can use more than one article, and don't copy one article completely.

Third, the format duplicate checking system generally has format requirements, and it is necessary to upload the whole article, otherwise it may affect the duplicate checking results.

Fourth, the multi-level comparison method takes the sentence as the smallest unit to detect, and then to the paragraph and the whole article. Sentences can be converted into sentences, and words can be replaced by synonyms to reduce repetition rate.

5. References and appendices generally do not participate in the test, and the system will automatically identify them. If there is a reference, try to quote the whole paragraph and mark the reference symbol. If the content is too short, the system may not detect it.
