The analysis of big data today is not the focus, I want to bring a little, there are many people are not very clear what is big data, I will give you two small examples to say what is big data. I do not know how many people here have worked in a big city like Tianjin, anyway, in Beijing, then there is one thing that is difficult, is to take a taxi, taxi especially especially difficult to hit the car during rush hour, I asked the people downstairs, I said master go? Too far, too close, too congested places do not go, he only go with him on the way to the place, you have no right to complain about him. You find ten cars downstairs to find a car with you on the road is particularly difficult, so now there is a taxi software, to two kilometers as a radius, looking for drivers on the road. That's big data, and big data isn't high end.

Some people say that big data is a new wave of concepts that come out of Silicon Valley, in fact, not, big data a long time ago, someone used, that is, Lin Biao, which is the god of war in my heart, he has a particularly good habit is to listen to the war report, others like to listen to the tactics and results of the war, he likes to listen to the number of guns and ammunition seized, so Mao Zedong said that Lin Biao is the biggest fan of money in the PLA. Have you ever wondered why he listens to this? Many people do not know, October 14, 1948 Liao-Shen Battle, Lin Biao over there listening to the battle report, suddenly he said stop, everyone is quiet, please say this battle report again, so said again, but also called everyone up to listen to it again what is the problem. Listened again, after Lin Biao asked three questions, generals, commanders, do you have a feeling in this battle, the number of captured short rifles and long rifles compared to other battlefields slightly higher than the proportion of captured carts and carts than other battlefields slightly higher than the proportion of captured and captured officers slightly higher than the other battlefields, and sure enough, we look over the previous record, really higher. Lin Biao said, I said that General Liao's house is in Hujia Wojiao, draw four troops to capture General Liao, 200,000 people captured 800,000 people, through this big data at least let the Chinese PLA died 40,000 fewer people.

Some people say what is the use of this data? Let me give you a simpler example, this movie everyone saw a while ago? Called "Small Times", we sampled 100,000 users, microblogging in the face of the small times of user data was analyzed, we found that the people in these places of the North almost no one commented on this matter, commented on the people basically in Hunan, Hubei, Jiangxi, Zhejiang, such a number of provinces, so we are not able to say that the small times of the placement strategy in these provinces will be better. Among them, women account for almost 80% or more, while men only account for a very small number, so if you are going to invest in advertising, is it not a bit more worthwhile to advertise women's products in Small Times. Among all the comments, you find that the fans of Nicholas Tse and Supremes appear especially often, does the addition of these people in "Small Time 2" make the ratings go up a notch? One hundred thousand concerned users inside, ranked in front of the unhelpful Guo Jingming, Ko Zhendong, and happy camp is also in the 100,000 people concerned about the inside, our "Small Times 2" is not with the "happy camp" to do a campaign, because their fans are overlapping. These are about the analysis of big data.
