Chapter 335 Investments

In the early days, the most common practice of search engines is to crawl the entire website directly, and at the beginning, only the title of the web page is generally crawled, which is like registering the names of all the books in the library in their own local database, and others want to find relevant content, use keywords to match in this database, if you find that the title contains this keyword, then you can think of this book "Nine Astronomy Station, Nine Astronomy Station Address Link." Pen "Fun" Pavilion www.biquge.info

Later, after the search engine was large-scale and corporatized, the company with deep pockets had a lot of money and could purchase a large number of servers and hard disks, so it began to crawl all the pages on the website, that is, users could not only search for titles, but also for full-text searches. This is undoubtedly an improvement, as headlines often contain only so much information that it is impossible to cover everything.

However, this is an era of information explosion, the Internet is an ocean of knowledge, there are thousands of websites, and there are often thousands of results from a keyword search, and if you find the information you need in these results, it has become a difficult problem.

This is something that all search engines are looking at, and it boils down to sorting web pages, and the better the pages, the better the ones, so that users don't need to spend much time finding the information they need.

This is easier said than done, and each search engine company has its own sorting algorithm, which is a trade secret and is not disclosed to the public. And users are very realistic, if your product is good, it can indeed bring convenience, then he will use it, and will recommend others to use it.

The bckrup discovered by Lin Hong was discovered only after seeing other people's recommendations, and when used, he found that its algorithm is indeed very strong, and he can usually quickly find the information he is looking for.

After his research, he found that this search engine uses an algorithm called Pagerank.

In fact, Lin Hong doesn't know if it's called this name, and the reason why he calls it pagerank is because this noun appears in the source code many times. (《》)

Each website corresponds to a pagerank value, and there is a database on the server to store the pagerank value of each website.

Lin Hong read through the entire source code, and he found that PageRank is divided into eleven levels, from 0 to 10, the higher the level, the better the quality, and the higher the ranking of the website.

As for how to calculate the PR value of the website, it is also very clever, it is calculated based on the number of links.

To put it simply, it is to count the links on those websites found by all spiders, these websites usually contain links to other websites, and regard it as a kind of vote, who has a link, will get a point, whoever has the most links, who has a higher score, and then convert this score, there is a PR value.

The core idea of this algorithm is that if your website is of good quality, then people will like to link to you and recommend it to others.

Lin Hong speculated that this kind of algorithm idea is likely to come from the scientific community's literature citing calculation principles.

When scientists write literature and papers, they usually need to consult a large amount of information, and they usually cite the information they have consulted at the end of their paper. It is generally accepted that the more citations there are, the higher the quality.

This is how the backrub website uses this method to rate web pages, so that users have a better experience.

Lin Hong saw a business plan on this server, and Larrypage, the director of the Nine Astronomy Station, seemed to be planning to commercialize the website and was looking for angel investors.

Seeing this, Lin Hong was a little moved.

He is very optimistic about this project, although it is only a prototype at present, and there are many shortcomings, but it does not matter, and it can continue to be improved.

This project is very much in line with the question he has been thinking about for a long time, that is, how to process this information in the era of information explosion and find business value from it. The latest chapter of the Templar

And obviously, this backrub fits perfectly.

Lin Hong thought about it for a long time and finally decided to invest in this project.

Lin Hong called up the bit messenger and sent a few messages to Phyllis, asking her to pay attention to the Stanford project and contact him in his name if they were looking for investment.

After sending these messages, he sent a text message to Phyllis, telling her to check it online when she had time.

Unexpectedly, as soon as the text message was sent, the other party immediately replied, saying that she would go online immediately and asked him not to leave.

Soon, on the Bit Messenger, Phyllis sent a message.

In fact, Lin Hong can also use email to communicate with her, but he is used to using bit messenger, and if email needs to be encrypted, it also needs to use encryption software such as PGP, but Phyllis has no talent for using these software, and is not willing to learn.

Therefore, when it comes to confidential information, they still tend to use bit messenger.

Phyllis: I'm here, am I still there?

Lin Hong: Well, yes.

Phyllis: Search engine project? How did you discover this item?

Lin Hong: Their website is already online, which is very good, and I am very optimistic about their development.

Phyllis: I'll take a look at it first.

Phyllis went to experience it according to the website given by Lin Hong.

Phyllis: Looks good, indeed. But wouldn't it be too small?

What Phyllis means is that the projects they invest in are basically relatively large, but this is a personal website, and the scale of investment is generally not large, and even if there is a return, it is basically not large.

Lin Hong: The founders are talented, and they are looking for angel investment, commercialization of the project, and the formation of a search engine company, if nothing else, I think it should be able to develop well, and like other Internet companies in Silicon Valley, if it can go public, the return rate should be very good.

Lin Hong didn't say one thing, that is, if after investing, he will consider participating in it and helping them. The reason why I want to invest in this project is that I am optimistic about the potential of this project, and on the other hand, I want to enter the Western IT industry through this way, and find some suitable talents by the way.

In this field, foreign development is at the forefront of domestic development, and China is lagging behind at least a decade in terms of both education and infrastructure construction. Lin Hong intends to use this project as an entry point to gradually expand investment in the IT field and attract world-class talents for his own use.

Phyllis: Where did you get this news from?

Lin Hong: Special channels. However, don't say that I already know the news, I think they will soon go to Silicon Valley or other places to meet with investors, and then you will show up again, and my specific information, don't disclose it for now.

Phyllis: Got it. I will find a professional to do an assessment. Also, how much stake do you plan to own?

Lin Hong: Naturally, the more the better, of course, not more than the proportion of founders.

Lin Hong didn't want to overstep his bounds, the main reason was that he didn't have time.

The other party's pagerank algorithm gave him a lot of inspiration, as long as he wanted, he could make a better product than the other party, but after all, he was only one person, and there were too many things to do, and it was impossible to do everything himself.

One of the solutions is to find good people to work with, provide their own funding or technology, and then let them develop on their own.

Phyllis: I see.

The two of them communicated for a while, and Phyllis quickly went offline. It's daytime in China, but it's midnight on her side, and she has to continue to sleep.

In her opinion, instead of investing in these industries, it is better to invest directly in financial products, which have large profits and a short return cycle.

However, the return on this investment turned out to be the most successful of all her investments.

Due to the hot weather, Wu Dong and Zhang Da were taking a nap, but Li Qi was not sleepy and couldn't help running to other bedrooms.

After a while, Li Qi came back and saw Lin Hong using the computer, so he walked up to him and said to him: "Boss, I just heard a news that our school has a BBS, called Shuimu BBS. ”

"Oh?" This news made Lin Hong a little surprised, but he was soon relieved, after all, Mizuki University is a first-class university in China, and it is understandable that it is ahead of other universities in this area. In addition, the campus network of Mizuki University has been established since the 80s, and the emergence of BBS is certainly inevitable.

"Do you know the access URL of Mizuki BBS?"

"This ...... I'll go ask again. ”

With that, Li Qi ran back and soon came back, holding a note with an IP address in his hand.

"Boss, this is it." Li Qi handed the note to Lin Hong.

Since it is an internal network, it is a local website, and you can log in directly without connecting to the Internet.

Lin Hong started the tel client and connected directly.

A white-on-black interface soon appeared, followed by a welcome message in the client.

"It's connected!" Li Qi shouted with some excitement.

His voice was a little loud, and he immediately woke up Wu Dong and Zhang Da, who were taking a nap.
