On the way home by car, Hang Yu got the news that several other groups had also succeeded. There is a letter of introduction from Secretary Bai, and then show the power of engineering simulation, and the next situation is similar to Hang Yu's side.

"I didn't expect that there are so many ways to develop big data, or I would do a big data blind date, maybe it will become popular. Qiu Xueyan felt it.

"Blind dates are mainly based on feelings, at most ask about family conditions, do you need big data. Hang Yu didn't think much about that, he had enough of his own products, and he didn't have time to continue to help Qiu Xueyan research.

"It mainly depends on the conditions, but it is actually difficult for them to figure it out after they meet a few times, and they can refine it with big data. It definitely works, but I don't know how effective it is. Qiu Xueyan said.

"The data must be true to be useful, and many of those people on the Internet write fake information, and they may not even be accurate in their academic qualifications. Your blind date business is like this, mainly because of the lack of authenticity. Hang Yu said.

Previously, the marriage company held a blind date meeting for 10,000 people, which was very lively, but it did not contribute much to the growth of the blind date business itself, but increased the sales of the RV business.

Qiu Xueyan didn't think much about it, she felt that the online blind date was a bit of a void, so she simply stopped working hard and treated the blind date as a gimmick, the main purpose was to publicize and attract people.

Hang Yu hadn't thought much about it before, but when he talked about it today, he felt that he still had to remind him.

"There's no way, it's so difficult to collect RV resources, people have brains, and they won't stand there and check for you. To ensure the authenticity of users' information, we can only rely on their own consciousness and our complaint and crackdown channels. Qiu Xueyan said.

"It's not completely impossible, if big data is all over our lives, such as RVs, shopping, businesses and other equipment, we can collect their real information. Many of your users will spend on Weibo and the two shopping platforms, and some information can be collected through their consumption records and express delivery records. Hang Yu said.

"It's... That's an exaggeration. Qiu Xueyan was dumbfounded.

"What's the exaggeration, we've been collecting user data, including yours. It is clear who buys a house and a car, and through these data, you can analyze what level the other party is approximately. Of course, no matter how good the analysis is, it is not as reliable as the direct knowledge, so we will continue to collect it in the future. Hang Yu said.

"Can these materials be blatantly taken out and used, if users see their salary level, living situation, and employment situation posted on the Internet, they will probably complain to us. Qiu Xueyan said.

"It can't be used directly, but it can be matched to judge the authenticity of the information filled in by the user. In addition, we can use it secretly, not to publish the data, but to use the method of confidential recommendation. Hang Yu said.

"Confidential recommendation?" Qiu Xueyan was puzzled.

"For example, if I want to find a sister paper on your website, then I need to fill in my approximate address and requirements first, and then the computer will match the data in the background, and select a female user who is closer to me and has similar conditions. However, on the computer, only the information filled in by female users is disclosed to me. Hang Yu said.

"I see, one thing on the surface and one behind the other. Qiu Xueyan said.

"Almost. Hang Yu said.

This practice is unethical, but as long as the true information is not disclosed, it is acceptable to the average user. In fact, technology is becoming more and more developed, and everyone knows that those Internet companies will collect their own information, and you can't do anything about it.

Sometimes a company sends advertisements directly in order to recommend its own products.

This kind of advertisement, which is clearly self-aware and clearly aimed at oneself, is very unpleasant. But over time, everyone will get used to it, and it is really convenient to position and publicize.

Hang Yu will also do positioning publicity, but he won't do it too obviously.

Different groups of users will receive different ads, but the ads do not have obvious information about them. When users see it, they think everyone will receive it, so they won't notice it.

This kind of advertising can reduce the number of times, if the whole range is placed, different ads will have to be placed many times, and everyone will have to receive many times, which will be annoying.

"You can try, but the public information doesn't match our match, I'm afraid that users will be suspicious. Qiu Xueyan hesitated for a moment before agreeing, obviously not used to doing this kind of thing.

"The unspoken rule is that everyone can guess something, but everyone doesn't say it. Hang Yu said.

"Okay. Qiu Xueyan nodded.

How to match the user profiles of different websites? It is generally through Weibo, because Jiangyan's products and cooperative products are all logged in with Weibo, and mobile phone numbers are required to create Weibo.

There are also those created with fake numbers, after all, there are minority, and this kind of person is not a consumer power. If you use your real number to create a Weibo, it will be much easier to match his information.

If the real-name system of mobile phone numbers is implemented in the future, the authenticity of the information will be further improved.

When I got home, it was already past nine o'clock in the evening.

The nanny doesn't stay at Hang Yu's house all the time, so sometimes they have to cook for themselves.

Cooking dinner with Qiu Xueyan is mainly Hang Yu's hand, and Qiu Xueyan just helps wash the vegetables. Seeing Hang Yu's skillful spoon flipping action, although she had seen it many times before, Qiu Xueyan was still very interested, and praised and amazed Hang Yu's cooking skills.

"Where did you learn to cook?" Qiu Xueyan couldn't help but ask.

"I started to help my mom cook when I was very young, my dad worked in other places, and sometimes my mom wasn't at home, so I had to cook it myself. Hang Yu casually found a reason, in fact, his cooking skills were practiced by being single for too long in his previous life.

Generally speaking, the longer a man is single, the better he cooks, and the longer a woman is married, the better her cooking skills.

Hearing Hang Yu's words, Qiu Xueyan seemed to imagine his "miserable" childhood, and couldn't help but love her mother.

"Let me try. Qiu Xueyan also wants to cook for Hang Yu.

"No, I want to get a good night's sleep tonight. Hang Yu decisively refused, he didn't want to be hungry at night, and he would wake up hungry when he fell asleep.

"What do you mean, my cooking is so unpalatable? Qiu Xueyan was angry.

"It's not bad, but it's not tasty either. Hang Yu said.

Qiu Xueyan's teeth itched, but she had to admit that the secret path had the opportunity to practice her cooking skills.

Although I usually don't need to cook by myself, when I marry Hang Yu in the future and want to go to his house for dinner, I may have to help my mother-in-law cook together, and if my cooking skills are too poor, I may be discriminated against.

"You go take a bath, the chicken soup will be stewed for a long time. Hang Yu said.

"I still stew chicken soup so late, and I can't sleep well if I'm too full. Qiu Xueyan spoke, turned around and went to the bedroom.

Hang Yu smiled slightly when he heard this, he used to go out for supper at eleven o'clock in the evening, and nine o'clock was not too late.
