The next day, Su Yan went directly to the teaching building. Today was the day he had made an appointment with Lu Yuanting.

When I arrived at Lu Yuanting's office, there were three men talking and laughing with Lu Yuanting in the office.

Seeing Su Yan's arrival, Lu Yuanting also stood up and made an introduction. These three people were the heads of the computer department. The main purpose of coming here this time was to see what Su Yan had and how dare he go to Haikou and search abroad.

Engines compete.

After Su Yan said a simple hello, the group, led by Lu Yuanting, went to a conference room and sat down. Next, it was time for Su Yan to demonstrate his core search engine technology.

Search engines require the use of web crawler technology, retrieval and sorting technology, web page processing technology, big data processing technology, natural language processing technology, etc. At this time in 2001, natural language processing technology and big data were not yet available.

The processing is also different from the concept of later generations.

But to put it bluntly, the core point of all search engines is actually one thing, algorithms.

Because everything revolves around algorithms.

"You are all computer experts, and you may have your own opinions on search engines, so I hope you can follow my own pace during the explanation. If you have any objections, you can raise them and I will give detailed answers.

.”

After saying this, Su Yan began to prepare to get to the point.

"Before showing the core of my algorithm, let's first take a look at the three major current algorithms, Baidu's hyperlink analysis, Google's pagerank algorithm and IBM's hits algorithm.

Among the three algorithms, almost everyone thinks that Baidu's hyperlink analysis is the most backward among the three algorithms. However, we still need to look at some things from multiple angles. Baidu's hyperlink analysis can to some extent

It can be regarded as laying the foundation for the development of search engines.

By grabbing the web page information, and then using the algorithm mechanism to sort these web pages, when the user enters keywords to search, the web pages arranged according to the mechanism are matched based on the keywords.

The current three major mainstream algorithms, no matter which algorithm they are from, the algorithm basis is actually the same. They are all carried out according to the above steps.

There is even a saying that Google’s algorithm actually plagiarizes Baidu’s hyperlink algorithm. We will not do too much research on this. So why can’t Baidu, the same search engine, fail to compete with Google in foreign markets?

The key is that Baidu's current ranking method is too simplistic and based on the basic ranking method that the more web pages that are hyperlinked to by other web pages in all results of a certain search, the higher the value.

This basic sorting method causes some correct web pages to be covered by some inferior web pages. In the end, bad money drives out good money, making it difficult for users to find what they need.

Google's pagerank has two more important things. The first thing is to interpret the link from page a to page b as the voting behavior of a to b. Google will evaluate the grades of a and b at the same time to form a ranking.

New level.

That is, each page has a PR value, and your PR value will become a reference for the PR values ​​of other pages.

Then the PR of each page is calculated repeatedly. Assuming that each page is given a random PR value, then after repeated calculations, the PR values ​​of these pages will tend to be stable, that is, a convergence state.

This also means that users can use Google's search engine to obtain the information they need more effectively than Baidu. As for why I don't take Baidu seriously, it is entirely because Baidu launched a bidding service not long ago.

"

When talking about Baidu's bidding business, Su Yan obviously paused.

And the comrades from the Institute of Planning also praised it at the right time, "As far as I know, the bidding business is Baidu's new profit model."

"So what do you think of this profit model?"

Su Yan looked at everyone calmly.

"It is indeed a good means of profit, and it can be regarded as a relatively accurate promotion for merchants. If you want to get on the search homepage, then the fee paid to Baidu will be a huge sum of money. If

If there are no major changes, this will be another important profit method for Baidu in addition to traditional advertising."

"It is true that after the bidding ranking system is launched, many companies will definitely be willing to pay the money. However, there is a problem here. How to solve the bidding review problem. After all, bidding, the highest bidder will get it. Then some false advertising money will be given to

What should I do if I can get on the homepage if I have enough? You must know that it is impossible to check other people’s products one by one when it comes to website review, and once a problem occurs, the loss suffered by the website is not ordinary. After all, search engines are more about reputation.

.”

Su Yan looked at the people who were lost in thought and couldn't help but breathed a sigh of relief. He knew that Baidu made a lot of money by relying on bidding ranking in later generations, but it was also criticized. Various Putian hospitals in later generations were

Make a fortune out of this, as the saying goes, Baidu treats doctors, and cancer starts.

If several people from the Institute of Design also became interested in this kind of bidding ranking, then Su Yan would rather postpone the search engine project and wait until Shenxiu Technology recovers to develop it on its own.

"Mr. Su, it sounds like you are not optimistic about Baidu's bidding ranking?"

A middle-aged man from the Planning Institute pushed up the gold-rimmed glasses on the bridge of his nose and looked at Su Yan and said.

As his words fell, the other three people, including Lu Yuanting, also looked at Su Yan, wanting to hear his answer.

"I am really opposed to bidding ranking. Because if we play bidding, we are betraying the trust of users. Why do users use search engines? It is because he wants to know something but he doesn't know it himself, so he actually comes here

Consult search engines.

At this time, the search engine plays the role of answering questions, and a good search engine is something that allows more users to get the answers they want. Slowly, when users become accustomed to using a certain search engine,

In fact, the core of this matter is that he believes in this search engine, and he believes that the search engine will give him the answer he wants.

At this time, if we use the bidding model that places the search results at the top of the rankings, users will actually have a trusting habit. They will trust the recommendations we put there more. This trust stems from their trust in the search engine and also from their trust in the search engine.

They don’t understand this bidding model or the Internet.

For example, what should we do if a user searches for cold medicine when he has a cold? If we pin a cold medicine merchant, the user will probably buy it. Indeed, the merchant can get relatively more accurate advertising effects, but what about our users?

They may believe our recommendations. I believe you all know that the Internet in our country has not yet been fully popularized. Many people only have a superficial understanding of the Internet. They do not understand things like bidding ranking at all.

, maybe they thought that the first result that appeared after their own search was the search result. And this result is probably just a bidding advertisement.

Our Internet is not perfect, and there are also big loopholes in supervision. I don’t want people to poke my spine and curse me many years later when they learn the truth. After all, some money can be made, but some money is real.

Unconscience.

As for how to make money, my idea is the Internet advertising business. At the same time, we also engage in bidding ranking, but we use the bidding ranking method to conduct advertising auctions.

After that, on the one hand, it sells advertising space through its high users and subsequent high-traffic products developed. On the other hand, it uses advertising alliances to match advertisers and traffic owners (small and medium-sized websites, small and medium-sized apps, media websites, etc.) to occupy the long-tail advertising market.

, and earn a commission from it.”

Shenxiu will not just be a search engine. We use search engines to consume users’ trust, which will actually directly affect future products.”
