1. First of all, it is necessary to understand that the detection algorithms of HowNet and VIP are different. The VIP algorithm chooses the word meaning fingerprint verification technology, while HowNet adopts the character-number segmentation method, so the standard of the algorithm is different.

2. Secondly, HowNet has a wider database and contains more data. HowNet has two comparative databases: the joint comparative database of college students' papers and the joint retrieval database of academic papers. If anyone plagiarizes the papers of previous graduates, it will definitely be found out. So from this point of view, HowNet is stricter than VIP, because VIP can't detect the contents of previous graduates' papers unless the school has its own self-built database.

3. HowNet is a comprehensive retrieval database jointly developed by Tsinghua University and Tsinghua, covering a wide range of disciplines. * * * Search more than 6,000 source journals, cited more than 7.9 million times, and updated daily.

Wei Pu was developed by Chongqing Wei Pu Information Co., Ltd., and its subject scope is narrower than HowNet, mainly involving engineering technology, agriculture, science, medicine and other disciplines. It can search more than 5,000 journals with more than 6.5438+0.4 million citations, and the update frequency is updated every two months.

Therefore, through the above comparison, HowNet is better in any aspect, which is why HowNet retrieval is the most authoritative and recognized reason in China. Among many requirements for professional title evaluation or doctoral and postgraduate graduation, HowNet retrieval is the most common one. The advantage of VIP retrieval lies in the fast retrieval speed and good effect of logical retrieval function, which can achieve better recall and precision. So both are authoritative searches. about
