Robin Li's Early Patent Exposure: Supporting Baidu's US $50 Billion Market Value

Baidu.

The patent is called hyper chain analysis technology, and its author is

The search that people use today is actually very intelligent, and search results are arranged orderly according to relevance, and can even be customized according to user history.

But in the middle of 90s, there was no real search engine, and the search results were jumbled. How to identify website quality and prevent cheating became a technical bottleneck that could not be broken through.

At that time, Robin Li, 28, was a senior technical adviser to Jones Company. He has led the development of the Wall Street Journal online version of real-time financial information system, which is also the first network real-time financial information system in the world.

At that time, there were 150 thousand pieces of information every day, so huge amounts of information that it was difficult for users to find the information they wanted quickly. It is urgent for a fast and accurate retrieval technology to solve this problem.

When he was thinking about how to solve the search accuracy technology, Robin Li suddenly thought of his indexing method of scientific papers in Peking University.

"How many papers are indexed by scientific papers determine the quality of a paper. Hyperlinks are references to pages."

Robin Li recalled, "the text on the hyperlinks is a description of the linked web pages. By this description, we can calculate the correlation between hyperlinks and pages."

This made Robin Li very excited. He immediately demonstrated the theory and compiled it. In 1996, he put forward the concept of "hyperlink analysis" and published relevant articles. In February 1997, he applied for a patent, Hypertext document retrieval system and method, patent No. 5920859.

The invention of hyper chain analysis technology has changed the situation of chaotic search and redundant information in the Internet, which has greatly improved the search results.

At an academic conference, Robin Li invited Infoseek CTO William Zhang to watch the practice of hyperlink analysis.

Robin Li entered ChinaTimes, ranking first in the website of China times, then searching IBM, and IBM official website ranked first.

William Zhang exclaimed: "no popular search engine can do it."

It is worth mentioning that Robin Li's hyperlink analysis points out the relevance of different text links. This thought foresight predicts that in the future, different language search engines may be different in main technologies.

Now, this prediction has become a reality. At present, there are different search engines in Chinese, English, Russian and Korean languages. Although the technology system has its own advantages, its essence is closely related to hyperlink analysis, such as Google.

Secrets of past events: page and Brin, or inspired by Robin Li

Ancient Chinese literati and friends often call each other "one word teacher", that is, each other's words give themselves great inspiration and inspiration.

In the Internet world, Baidu founder Robin Li is actually the founder of Google Larry Page and Sergi Sergi (Sergey Brin) as a teacher.

Former Google China President Li Kaifu (micro-blog) has mentioned in micro-blog that three people such as Robin Li and page are the earliest proponents of search engine ranking algorithm.

But he may not know that there is a little known past between Robin Li and page.

In February 1997, Robin Li submitted a patent application for the hyperlink analysis; in April 1998, Robin Li went to Australia to make a speech search ahead technology, among which there were page and Brin on the audience; in October 1998, Google went online, and applied for PageRank patent in the same year, but because of the similarity between Pagerank and the super chain analysis patent applied by Robin Li, the United States Patent and Trademark Office approved PageRank patent application in September 2001.

According to the exposure of Robin Li papers, the essence of hyperlink analysis (ESP) technology is a voting mechanism. A link can be considered as a web page's voting on another page, and the number of votes determines sorting.

In addition to the basic voting mechanism, the technology also has two characteristics: using link text as an important information to make the search engine more accurately understand the content of the target web page, thereby effectively improving the relevance of the search results; adjusting the voting weight according to the authoritativeness and recommendation methods of the voters themselves, thus effectively improving the authority of the search results.

Robin Li's hyperlink analysis points out the trend and direction for the development of modern search engine, which indicates that Internet search engine has entered a fast developing era.

Robin Li's related hyperlink analysis has been cited in various studies. Up to now, hyperlink analysis has been cited by 211 international patents and widely adopted by the world's major search engines.

For example, hyperlink analysis sets up a new platform for search, and others use this new platform to derive personalized development.

From 1997 to 2000, Robin Li also analyzed and perfected his hyperlink theory through his works. He published it in the Journal of the IEEE (American Institute of electrical and Electronic Engineers) and studied new solutions in the field of Internet search. Subsequently, Robin Li's new technology invention applied for several patents.

At the end of 1999, Robin Li returned to the motherland to create Baidu, a Chinese search engine company.

Today, Baidu has grown into the largest Chinese search engine and the largest Chinese website in the world.

When Robin Li led Baidu to win the 80% market share of China's search, many people thought that it was excellent business management to achieve Robin Li and Baidu. But in Robin Li's opinion, the focus and innovation of search technology is the key to Baidu's growth.

He said: "in China, silence is not management, but technology.

Too few people really care about the progress of technology. Too many people are obsessed with management as a war.
