Official website of PaperYY said, "With the fingerprint matching algorithm based on big data developed by Dr. Haigui for many years, the matching speed is increased by 10 times compared with the conventional matching, and the duplicate checking result can be obtained in a few seconds while ensuring the duplicate checking quality".

Hownet, on the other hand, takes half an hour as fast as it takes a few hours as slow. How long does it take to check the weight of the network? For details, please refer to how often you check the weight of HowNet. In addition, PaperYY does not support duplicate checking of PDF, and the uploaded document formats are limited to doc, docx and txt formats. ?

Second, the difference between detection rules and principles

Hownet is continuous 13 characters are similar, which is judged as duplication by the system, and the threshold of Hownet system is 5%, so there will be errors in simultaneous detection of the same article.

At present, the principle of detection rules of PaperYY has not been clearly explained in official website, and only one sentence is given: "Four returnees have studied fingerprint comparison technology for many years, and created original classification comparison technology on the basis of big data cloud, with an accuracy rate of over 90%, pre-processing fingerprint technology and second-level response, making detection and duplicate checking more accurate".

However, it is definitely different from HowNet. China HowNet is nationwide, because the detection principle of HowNet is a patent invented by China HowNet, and it also won the Science and Technology Progress Award!

Third, the differences of system functions.

PaperYY has a self-built comparison database to test the effect of duplicate checking. In addition, PaperYY also has automatic and manual weight loss services. HowNet does not have such humanized service. There are also many softwares for automatic weight loss, which are described in detail in "What softwares are there to lose weight and modify the repetition rate of papers" of Academic Misconduct Network, but the author still recommends PaperEasy's manual weight loss service.

Fourth, the difference in charging standards.

At present, PaperYY charges 1 yuan 10000 words, and some students will find that the revocation of its second-level domain name is completely free! HowNet does not support individual users to register accounts. Students can only go to the library to check the duplicates. The library either charges fees or limits the number of exams.

You can also go to some duplicate checking platforms, such as the "HowNet Paper Duplicate Checking Portal" of Academic Misconduct Network, and directly connect to China HowNet official website without registering an account. Self-service detection in the whole process is safe, accurate and fast! ?

Verb (abbreviation of verb) compares the differences in the scope of the library.

PaperYY official website did not explain the database resources, which exceeded 65.438+0.20 billion of massive fingerprint data, covering most periodicals, books, papers and Internet data.

There are 90 million Chinese periodicals, 6 million dissertations and discussion papers, 6,543,800,000 Chinese books, 6,543,800,000 newspaper data, 6,543,800,000 Chinese and foreign standard patents and 65,438,800,000 Chinese and foreign Internet pages. The comparison database of HowNet includes academic discussion database, network resources and joint comparison database of college students' papers. HowNet can detect senior graduation thesis, and try not to refer to senior thesis.

Sixth, the difference of college recognition.

99% of colleges and universities adopt the detection system of China HowNet, and China HowNet is now the largest Chinese online library in the world. With the soaring price of HowNet. The paper duplicate checking service provided by PaperYY still needs to enhance brand awareness, compare resources and algorithm rules.
