In the recent Double Eleven Carnival Shopping Festival, many people only need a few minutes to buy their favorite goods. Different from the traditional mode of trying on and shopping in several shopping malls, with the support of big data, all people have to do is browse, compare and click online. Sometimes, even the steps of Taobao are omitted, and the network will quietly push the products that users like under the analysis of big data.

Big data is providing various conveniences for people's lives, and the time for reading, shopping and storage is greatly shortened. The discussion about big data has penetrated into all fields of economy, society and life. Day after day, year after year, engineers have discovered an amazing reality: big data has begun to be independent of people, forming a separate information space outside the dual space of human society and nature.

1 17 at the 20 15 international high-end seminar on digital knowledge service science and engineering held in Beijing, Pan Yunhe, an academician of China Academy of Engineering, said, "Fifty years ago, human beings were still in a dual space. At that time, information was still generated by people and came from human society. People write books, people meet and communicate, people use the media, and computer information is input by people. Later, people began to connect information. With the Internet, mobile communication and search technology, information began to come directly from the physical world through the Internet. Last year, a related survey found that 60% of online information was not sent by people, but by reptiles. The information flow on most networks is not occupied by people, but by robots. This is a very surprising era. " Pan Yunhe said.

Is the era of big data really centered on "data"? Many countries have begun to make a fuss about "data". On 200 1, the government of China and the American Natural Science Foundation began to enter an international cooperation project: digital library. The goal is to enable all people to acquire the knowledge of all mankind through the Internet anytime and anywhere. The project has digitized 2.5 million books.

"Although the project was originally designed to provide books and materials to the whole world, it was later found that it can not only borrow books, but also provide many new services. For example, through it, you can visit places of interest online, as well as the digital three-dimensional sculpture of Dunhuang Grottoes. For example, the project digitizes more than 4,000 works by more than 900 calligraphers in China, so it can help people who study Chinese and calligraphy all over the world practice calligraphy and can also be used for calligraphy design. " Pan Yunhe said.

There is even a doctoral student from Zhejiang University who compiled a "Red Chamber Recipe" with big data. What he has to do is to link all kinds of cooking contents in A Dream of Red Mansions with all kinds of recipes, find out all kinds of cooking techniques in TV stations, and also find out plant planting methods and nutrition in botany and agronomy.

"We found that if massive data can be connected with each other, we can generate a lot of new knowledge from it. We call these interrelated mass knowledge data sea. If a library has a digital sea, it may develop into a digital library, which is completely different from the original library. " Pan Yunhe said.

Therefore, in the era of big data, not only a "master" set of data, but also more functions can be generated. It is not enough to just mine big data, and we should move from big data to big knowledge.

At the seminar, the reporter learned that Zhejiang University is transforming big data of traditional Chinese medicine into new knowledge. They connect prescriptions, diseases, doctors and patients with each other, and connect the Internet, digital libraries and professional data for in-depth search. This can not only study the composition of a compound in traditional Chinese medicine, but also identify various medicinal materials and analyze how to combine them, which is very helpful for doctors to explore new prescriptions.

Based on the exploration from big data to big knowledge, China Institute of Engineering established the International Engineering Science and Technology Knowledge Center on 20 14, hoping to connect a number of digital libraries, professional databases and various engineering science and technology-related websites around the world, so that a large amount of data can form a data sea, and new knowledge and new understanding can be obtained from different angles with the help of the characteristics of the data sea.

Pan Yunhe said: "The International Engineering Science and Technology Knowledge Center will provide academicians with the knowledge they need to study China's strategy. After the center develops to a certain extent, it will be open to all engineers, so that engineers in China can use it to develop new products and learn about the research progress in this field all over the world. In addition, this center has to shoulder the heavy responsibility of supporting China's industrial transformation. "

Zhou Ji, president of China Academy of Engineering, said at the seminar that the combination of big data with smart terminals and mobile Internet has further promoted the deep integration of informationization and industrialization, further opened up the mode of scientific and technological innovation and economic development, and further improved the scientific level of political leadership and industry development decision-making. We are experiencing a new round of information revolution and industrial transformation based on big data.

The above is what Bian Xiao shared about the real "data" as the center in the era of big data. For more information, you can pay attention to the global ivy and share more dry goods.
