Li Yanhong's super chain analysis patent

Baidu founder Robin Li was one of the top search engine engineers in the United States before returning to China to create that Baidu. It is said that when Robin Li was looking for venture capital, the investor asked the technical experts in the other three search engine industries a question: who should be asked to understand the search engine technology. Two of the three experts who were asked answered: Ask Robin Li about the search engine. From this, investors concluded that Robin Li is one of the people who know search engines best.

This is actually a real life application similar to link relationship. To judge which page is the most authoritative, you should not learn how to say it, but also how to evaluate other pages.
In 1997, Robin Li submitted a patent application called "Hyperlink File Retrieval System and Method", which was much earlier than the invention of PR by Google's founder. It is a very forward-looking research work. In this patent, Robin Li proposed a link based ranking method different from traditional information retrieval systems.
In addition to indexing pages, this system also establishes a link thesaurus to record some relevant information about the link anchor text, such as which keywords are contained in the anchor text, the page index of the link, the total number of links containing specific anchor text, and which pages are pointed to by links containing specific keywords. The thesaurus contains not only the keyword prototype, but also other derived keywords of the same stem.
Based on these link data, especially the anchor text, link based file dependencies are calculated. When users search, they will use the link based relevance and the traditional relevance based on keyword matching to get more accurate rankings. ( High end website construction )
In today's view, this link based correlation calculation is the norm of search engines, and every SEO person knows it. But 134 years ago, this was undoubtedly the concept of Baichang Innovation. Of course, the current search engine algorithm considers links not only as anchor text, but also as complex lines.
The owner of this award was Li Yanhong's company at that time, and the inventor was Li Yanhong himself. Interested readers can check the "Hyperlink File Retrieval System and Methods" issued by the United States Bureau of Trade and Science at the following address.
