*? Appropriate citation of references.

Unreasonable use of references will lead to high text repetition rate, so scientific citation becomes the key to literature reference.

Select the appropriate reference type.

The detection of academic misconduct documents is to compare the detected documents with the documents collected by the detection system, find out the repeated parts of words, and then identify plagiarism. The comparison of academic misconduct document detection systems such as China HowNet covers academic journals, excellent doctoral dissertations and other types of documents.

The test shows that the quotations come from informal publications, online documents, quotations and so on. And the proportion of plagiarism detected will increase, and many will be judged as "plagiarism".

(1) should first cite the published literature contained in the comparison source of the detection system.

(2) Seriously quote the contents of books and foreign documents. Because books and most foreign documents are not included in the comparative source, it is difficult to detect such documents and judge that they are duplicates of other related cited documents. If necessary, the original or copy of the quotation should be attached for verification.

(3) Try not to choose blog, electronic bulletin and other network resources and references. Although the academic misconduct system began to pay attention to the collection of online documents, most online documents such as blogs and electronic announcements are not public publications, so it is difficult to ensure their correctness and scientificity, and it is easy to repeat words because of random or misleading references.
