Chapter 335 Investment

In the early days, the most common practice of search engines was to directly crawl the whole website, and at the beginning, they usually only crawled the title of the web page, which is like registering the names of all books in the library in their own local database. If others want to find relevant content, they use keywords in this number. According to the matching in the library, if you find that the title contains this keyword, you can think that the "book" is what the user is looking for, and tell the user the "book shelf" where the "book" is located and let him visit it.

The book is the website, and the bookshelf where the book is located is the address link of the website.

Later, after the scale of search engines and corporation, the rich companies had a large amount of funds and could purchase a large number of servers and hard disks, so they began to grab all the web pages on the website, that is to say, users can not only search for titles, but also search the full text. This is undoubtedly an improvement, because the title usually contains only so much information that it is impossible to cover all the content.

However, this is an era of information explosion. The Internet is a sea of knowledge. There are thousands of websites, and the results of a keyword search are often thousands. If you find the information you need in these results, it will become a difficult problem.

This is a problem that all search engines are studying. In the final analysis, the more web pages are sorted, the better the web pages should be at the forefront, so that users don't need to spend much time to find the information they need.

It is easy to say, but it is quite difficult to do. Each search engine company has its own sorting algorithm, which are business secrets and are not disclosed to the public. And users are very realistic. If your product is good and can indeed bring convenience, then he will use it and recommend it to others.

The bckrup found by Lin Hong was found after seeing other people's recommendations, and after using it, he found that its algorithm was indeed very powerful, and usually he could quickly find the information he was looking for.

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

In fact, Lin Hong doesn't know whether it is called this name or not. The reason why he called it pagerank is that this noun has appeared in the source code many times.

Each website corresponds to a pagerank value, and there is a special database on the server to save the pagerank value of each website. Lin Hong read through the whole source code. He found that the pagerank is divided into eleven levels, from level 0 to level 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, which is calculated according to 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, which are regarded as a kind of vote. Whoever has a link gets one point. Whoever has the most links, the higher the score. Then convert this score, there will be p R value,.

The core idea of this algorithm is that if your website is of good quality, others will like to make links for you and recommend them to others.

Lin Hong guesses that this algorithmic idea is likely to be a literature reference calculation principle from the scientific community.

When scientists write literature and papers, they usually need to consult a large amount of information, and generally refer to the information they have consulted at the end of their papers. It is generally believed that the more literature is quoted, the higher the quality.

This backrub website uses this way to rate web pages, so that users can get a better experience.

Lin Hong saw a business plan in this server. Larrypage, the director of this website, seems to be planning to commercialize the website and is 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, there are still many shortcomings, but it doesn't matter, and it can continue to be improved.

This project is very much in line with a problem he has been thinking about, that is, how to process this information and find commercial value from it in the era of the Big Bang Theory.

And obviously, this backrub is exactly in line.

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

Lin Hong transferred the bit messenger and sent a few messages to Phylize to ask her to pay attention to Stanford's project. If they seek investment, they will contact her in his name.

After sending these messages, he sent a text message to Phylise, asking her to check it online if 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 told him not to leave.

Soon, on the bit messenger, Phylise sent a message.

In fact, Lin Hong can also communicate with her by email, but he is used to using bit messenger. If emails need to be encrypted, he also needs to use encryption software such as pgp, but Phylize has no talent for using these software and is unwilling to learn.

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

[Felice: I'm coming. Are you still there?]

[Lin Hong: Well, I'm there.]

[Felice: Search engine project? How did you find this project?

[Lin Hong: Their website has been launched, which is very good. I am very optimistic about their development.]

[Felice: Let me take a look first.]

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

[Felice: It really looks good. But isn't it too small?

Felice means that the projects they invest in are basically relatively large, but this is a personal website. Generally speaking, the investment scale is not much, and even if there is a return, it is basically not much.

[Lin Hong: The founder is a talent. They are planning to seek angel investment to commercialize this project and set up a search engine company. If nothing unexpected happens, I think it should be able to develop well. Like other Internet companies in Silicon Valley, if they can be listed, the rate of return should be considerable.]

Lin Hong didn't say anything, that is, if he invests, he will consider participating in it and helping them. The reason why I want to invest in this project is that on the one hand, 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 China. Whether it is education or infrastructure construction, China has lagged behind for at least ten years. Domestic talents in this field basically need a period of time to be trained, and ready-made world-class talents still have to be found from the Western world. Lin Hong intends to take this project as an entry point, gradually expand investment in the IT field, and attract world-class talents for his own use.

[Felice: Where did you get this news?]

[Lin Hong: Special channel. However, don't say that I already know the news. I think they will go to Silicon Valley or other places to meet investors soon. Just show up at that time. Don't disclose my specific information for the time being.]

[Felice: I got it. I will find a professional to evaluate it. In addition, how many shares do you plan to occupy?

[Lin Hong: Naturally, the more the better. Of course, it can't exceed the proportion of founders.]

Lin Hong doesn't want to replace him. The main reason is that he doesn't have time.

The other party's pagerank algorithm inspired him a lot. As long as he wants, he can make better products than the other party, but after all, there is only one person. There are too many things to do, and it is impossible to do everything by himself.

One of the solutions is to find excellent talents to cooperate, provide their own funds or technology, and then let them develop alone.

[Felice: I know.]

After a while of communication, Phylise quickly went offline. It's daytime in China at this moment, but it's midnight on her side. She has to continue to get some sleep.

She is actually not very optimistic about Lin Hong's investment proposal. In her opinion, instead of investing in these industries, it is better to invest directly in financial products, with large profits and short return cycles.

However, the return on this investment surprised her later, and eventually became the most successful investment in all her investment projects.

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 dormitories.

After a while, Li Qi came back. Seeing that Lin Hong was using the computer, he walked to him and said to him, "Big boss, I just heard the news that there is a bbs in our school, called Shuimu bbs."

"Oh?" Lin Hong was a little surprised by this news, but he was soon relieved. After all, Shuimu University is a first-class university in China, and it is understandable to be ahead of other universities in this area. Moreover, the campus network of Shuimu University has been established in the 1980s, and the emergence of bbs is inevitable.

"Do you know the website of Shuimu bbs?"

"This... I'll ask again."

With that, Li Qi ran back and soon came back. He held a note in his hand with an IP address 166.111.1.11.

"Big boss, that's it." Li Qi handed the note to Lin Hong.

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

Lin Hong started the telnet client and connected it directly.

An interface with white words on a black background soon appeared, and then the welcome message began to be flashed out in the client.

"It's connected!" Li Qi shouted excitedly.

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