Three networks refer to the three major retrieval systems in China: HowNet, Wanfang and VIP. Papers can be searched by three networks, which means that the articles published by the author can be searched by these three data platforms. Search on three networks is a requirement and standard for the publication of papers. Some domestic academic papers have this requirement, and some only require HowNet retrieval.

HowNet, Wanfang and VIP are all authoritative databases in China, but in comparison, HowNet has great popularity and influence in China. Therefore, in the demand of publishing papers in various fields, the retrieval of HowNet is a universal demand, while the retrieval of Wanfang and VIP are relatively few, and the retrieval of publications or documents by HowNet is also the largest. Whether it is work, study or promotion assessment at ordinary times, the role of HowNet is very obvious.

Although HowNet is more useful, it does not mean that other databases are useless. In the evaluation of professional titles or other assessments, the retrieval of other databases is also recognized. According to the identified system, you can choose the publications retrieved from the corresponding database and publish your own articles according to specific requirements. The articles searched by Triple Play are usually more obvious than those searched by HowNet, and have a wider scope of application.
