[Entertainment] website predicts "card House" will be red

Netflix has 33 million users all over the world, and it's clearer than anyone who likes to watch movies.

Netflix, the US online video site, also benefited from big data.

Netflix's first business was to rent DVDs, now offering 36 million of customers online to watch the movie business. Through numerous data analyses, Netflix has successfully predicted that the American play "card House" will be red.

Netflix, which has 27 million subscribers in the United States and 33 million in the world, knows more about movies and TVs than anyone else. Research has shown that daily peak-hour web downloads are from Netflix's streaming services, and last year people watched streaming video online more time than physical DVDs.

Life] "Magic Carpet" can automatically alarm

The number of steps the carpet stores, if the owner's step is less than the normal range, will issue an alert

The University of Manchester has used large data to invent a "magic rug" that can help the lone-person to alert when an anomaly occurs. On the surface, "magic carpets" are no different from ordinary carpets, but they are also laid on the floor, but "magic carpets" store the number of times a single person walks every day. If the single person walks less than normal in the day, the Magic carpet will alert you to the possibility of an accident as soon as possible.

Blueyonder, a company of 85 employees, is a company that analyzes large data. The company provides "accurate forecasts" for retailers such as Wal-Mart by combing the supermarket card information, weather information, school vacations and traffic reports.

These "predictions" are important to businesses because they avoid shipping errors and reduce storage costs.

For example, Blueyonder had suggested that a supermarket put milk, chocolate bars and apples together, and a few days later, sales of these three items increased significantly. The real reason is that Blueyonder learned about a new school near the supermarket, and the company analyzed the crowd characteristics and came to the conclusion.

View: Need to beware of "data tyranny"

Yes, big data is a powerful thing in areas like business. But for the average consumer, the pros and cons are the most important?

A survey by the Austrian-American company shows that 75% of people do not want companies to store their personal information, and 90% are against companies collecting records of web browsing.

"Today, our social networking society has a knack for creating panic," says Boyd, a senior researcher at Microsoft Research. In the big data age, the fear of privacy leaks is a source of intense tension and anxiety. It is generally accepted that the most worrying thing is that you do not know when your privacy is inadvertently leaked out. ”

One of the most worrying is the unrestricted use of such data. The American best-selling book, "Outbreak", pointed out that human behavior seems random disorder, but in fact there is some kind of law. The social network is so developed today, big data magnifies human behavior and makes it possible to predict people's personalities and journeys relatively accurately. So, don't rule out the possibility that after a day's work, you haven't decided where to go, and the data center has already predicted exactly where you're going.

This brings us to the alert: how to define the rights and interests of large data in the big Data age? How to control the risk of using large data? How to maintain the data democracy of our society?

In addition, how many people would really like to accept a "digital-driven economy" of the world? Do you really want to live in a world so clearly predicting the future that data can predict how your child behaves in school, what works for him or her, how likely he or she is to become a criminal, how likely he is to get sick?

Can a television or music record company better cater to the tastes of audiences or audiences through data analysis, but does it really outweigh the benefits of the creative industry? Where are the innovations, instincts, and surprises?

Internet expert Yevgeny Morozov proposed the concept of "data tyranny", noting that political and economic decisions based on large data are checked at intervals by independent auditors to prevent the misuse of digital power.
