? First, database comparison
HowNet: China Academic Journals Online Publishing Database, China Doctoral Dissertation Full-text Database/China Excellent Master Dissertation Full-text Database, China Important Conference Papers Full-text Database, China Important Newspapers Full-text Database, China Patent Full-text Database, Internet Resources, English Database, etc. Some books are not in the database of HowNet, so plagiarism cannot be detected, mainly from the local literature collected by HowNet.
PaperPass:PaperPass's fingerprint database contains more than 90 million academic journals and dissertations, and an Internet webpage database with a number of more than 654.38 billion.
Second, the test language comparison? ?
PaperPass is the world's first Chinese document similarity comparison system, which only detects Chinese.
China HowNet can detect Chinese and English.
Third, the comparison of the principle and rules of algorithm duplicate checking? ?
HowNet adopts semantic level detection technology, and there is no concept of "lowest level detection". When the system identifies duplicates and references, it will make a judgment according to the context.
PaperPass takes sentences as the smallest unit, and the report is detailed;
Fourth, the comparison of recognition ability? ?
HowNet can identify the title and will not count it as repeated similarity; Automatically identify chapters according to the directory system; Tags and references can detect citations.
Due to the problems of inconsistent citation format, nonstandard reference format and false citation, PaperPass will no longer distinguish between "similarity" and "citation" in order to provide users with strict and responsible test results. PaperPass detection system is a tool to provide users with the basis for revision in paper revision. Whether the similar parts (in red) displayed in the system belong to normal quotation will be left to the user for approval.
? 5. Comparison of accuracy and authority? ?
China Knowledge Network is a national knowledge infrastructure project in China. The information construction project, which aims at realizing the dissemination, enjoyment and value-added utilization of knowledge resources in the whole society, was initiated by Tsinghua University and Tsinghua Tongfang and was established in June 1999. It is a recognized authoritative academic misconduct detection system.
PaperPass website was born in 2007, which is the first Chinese literature similarity comparison system in the world. After eleven years' operation, it has developed into an authoritative and reliable online website for checking Chinese originality and preventing plagiarism. The dynamic fingerprint leapfrog scanning detection technology independently developed by the system has been ahead of other detection systems at home and abroad, and has become the leader of paper plagiarism detection technology.
Comparison of format requirements of intransitive verbs
HowNet dissertations are tested as a whole article, and the format may have an impact on the test results. It is necessary to submit the final submission format for testing, so as to minimize the impact, and a few tens of impacts may not be detected. But it will not affect the passage. The algorithm of the system is complex, and there may be small plagiarism that was not detected for the first time after each revision of the paper.
PaperPass detection does not require high format, because there is a copy-and-paste process in the detection process. Detection is basically in text format.
Through the comparison of the above six aspects, we can draw the following general conclusions: HowNet database mostly comes from local documents, and paperpass mostly comes from 9000 academic journals, dissertations and Internet data. There are still some differences between the two databases, and the algorithm of paperpass is not so accurate. Sometimes your article is compared with a completely irrelevant article. Therefore, the result of paperpass is generally higher, but this does not mean that the detection in HowNet will be 100% lower than paperpass, and there is no saying that paperpass algorithm is stricter. PaperPass detection system is most suitable for paper revision.
