Usually, after graduates finish their graduation thesis, the inevitable obstacle is to check the duplicate. Checking duplicate is a key step to identify whether a student's paper is original or plagiarized. The school will also have a rule that the repetition rate cannot be higher than a few percent, which is a rigid rule. There may be some repetition, because students will actually refer to other documents or give official definitions of nouns. This will be repeated with other published articles. If it exceeds the percentage standard set by the school, it will be considered that the student has a high citation and is suspected of plagiarism.
Because many schools have only one chance to check the duplicate, if they fail, they will face the punishment of delaying graduation. Therefore, many students will go to other platforms to check the duplicate before submitting them to the school, and then modify their papers according to the instructions, and then submit them to the school for duplicate check after insurance. There are many platforms for duplicate checking. There are free and official ones in the official account of WeChat, such as Vanke, HowNet and Weicensus.
The data of duplicate checking of each platform will not be completely consistent, because the duplicate checking of each platform is mainly based on the existing literature database in its own website. If it is free in the official WeChat account, they generally have a high duplicate checking rate, because they basically have a collection of documents of many websites, which are inaccurate and have many vague parts. However, if you compare the official HowNet, Vanke, VIP, etc. You will charge a certain fee, and the price will be set according to the number of words or articles in the paper. The price of master's thesis and undergraduate thesis is also different.
In fact, the data found on these duplicate checking websites are not the same, but students should choose the one cited by their own school to check duplicates, which will be closer to the final result, and check duplicates several times to ensure that the citation rate is lower than the school standard.
