Micro-census basically covers most academic journals, that is to say, once the author's article quotes or draws lessons from academic journals, micro-census basically covers academic journals, and in the detection process, academic journals similar to articles will be automatically identified and compared with databases.

Wei census repeatedly uses keyword identification technology, that is, even if some sentences of the author are original, as long as their keywords are duplicated with those of other articles, Wei census is repeatedly used as suspected plagiarism, which is also the reason for the high repetition rate of Wei census in articles such as law and economics.

Although keyword recognition technology can identify most plagiarism to a great extent, it may also misjudge the author's originality as suspected plagiarism. This calculation rule is stricter and more unreasonable than HowNet.

Judging the authenticity of the duplicate checking system:

1. To judge whether the duplicate checking system uses official website, the first criterion is whether official website is followed by cn or com. For example, the papertime double check system uses papertime plus. cn。 There are also third parties or impostors.

2. The second judgment is the duplication check and duplication reduction system. For example, if you enter official website in papertime, you will only see a duplicate check in papertime. If you enter a website which contains many duplicate checking systems, it is definitely not official website but a third-party duplicate checking website.

3. If you enter a company that includes HowNet duplicate checking system, papertime duplicate checking system and Victoria census duplicate checking system, it must be a third party fraud, which is not safe!

4. There is another verification method. If you find the papertime duplicate checking system, enter this system, click "Recharge Center" and pull it to the bottom. If you enter "463092" in the exchange code, you can change the number of duplicate words, which means official website, because only official website can change it.

5. Let's talk about the weight inspection system of HowNet. The checkweighing of a Baozhi. com is an agent. It can't be said that they are all fake, but many of them are fake. It's too hard to tell. In case it is a fake, this paper is likely to be sold. Because the duplicate checking system of HowNet is not open to individuals, but only to magazines, schools and other institutions, you can call HowNet for consultation, check with customer service in official website or ask in your school library.
