Fourth, the reference is different.
1. hownet: an information construction project aimed at realizing the dissemination, enjoyment and value-added utilization of knowledge in the whole society. Initiated by Tsinghua and Tsinghua Tongfang.
2.VIP: a world-renowned Chinese professional information service website and the largest comprehensive literature service website in China.
3. Wanfang: a large-scale online library developed by Wanfang Company, covering periodicals, conference minutes, papers, academic achievements, academic conference papers, etc.
Fifth, the impact is different.
1, hownet: With high-quality content, leading technology and professional service, China Hownet enjoys a high reputation in the industry.
2.VIP: We have established strategic cooperation with Google Academic Search Channel, Baidu Library and Baidu Encyclopedia successively.
3. Wanfang: It is the only full-text library of academic conference literature in China. It mainly includes the papers of national academic conferences organized by various societies, associations and research associations since 1998, involving natural science, engineering technology, agriculture, forestry, medicine and other fields. It is an indispensable helper to understand the academic trends in China.
Finally, talk about personal experience. First of all, the industry leader HowNet has the largest audience. In terms of quantity, it covers a wide range, has the advantages of periodicals and doctoral dissertations, and has perfect copyright cooperation, and can basically get all the retrieved ones. If it is not enough, I personally think that the user experience is average, and there are few old documents designed by using the interactive package library page. And the cost is high.
The second vip. As a periodical, VIP is still ahead of CNKI in breadth and collection time, and its meta-integrity is also the highest, so its importance is becoming more and more important in this era. In addition, the new periodical platform has done a good job in interface and user experience. If it is not enough, it is better to meet the audience. Except for periodicals, others are a little short of money. Some periodicals have been sorted out, but they can't get them without copyright, which is a bit uncomfortable. The audience is also much smaller, and it is not as famous as HowNet.
Finally, Wanfang. Wanfang's revised platform has also made great efforts in the world, and the page design, function and presentation are all well done. In the early days, he reached an exclusive cooperation with the medical association by virtue of his relationship, which included many high-tech periodicals, so Wanfang got along well in the medical college and medical company of the hospital. The disadvantage is that the full-text rate is a bit low, with no bright spots and no slots. Checking the weight is not as good as VIP's.
Hownet is undoubtedly the most comprehensive, but it doesn't mean that everything can be found. Some hownets don't have VIP wanfang. So you have to use them all, but HowNet is more expensive and VIP is cheaper.
