Since entering the information superhighway in 1970s, the development of Internet has been striding forward in innovation and change. Every day, when we open the Internet, we are greeted by various possible or ongoing changes. At present, when people are still talking about cloud computing, the era of big data has quietly arrived.
From the contact platform to the browsing platform, to the interactive platform, to the work platform, the Internet is always moving forward in constant development. Wu said that with the continuous development of the Internet and gradually entering the era of big data, urban data, enterprise data, medical data and website data have become an important part of our virtual and real life.
What is big data? Wu explained that big data refers to a collection of data whose contents cannot be crawled, managed and processed by conventional software tools within the allowed time. Of course, the standard of big data scale is constantly changing. At present, it is generally believed that the size of a single data set is between tens of TB and several PB.
There is no doubt that big data will accelerate the evolution of the Internet. The new format spawned by big data will also make our work easier, our economy more active and our life more convenient. He Hezhen said.
Big data can provide macroeconomic analysis services. The economic index forecasting system of Japanese companies searches 480 economic data that affect manufacturing industry from Internet news, and calculates the PMI forecast value of purchasing managers' index.
Big data can strongly support information consumption. 60% of online shopping in China is a substitute for shopping in physical stores, and 40% is newly purchased for convenience and variety. E-commerce is more conducive to the needs of mobile phone users, and big data will further promote their sales.
Big data can also provide consulting services. There is a climate company in Silicon Valley, which obtains decades of weather data from the US Meteorological Bureau and other databases, and makes accurate charts of rainfall, temperature, soil conditions and crop yield, so as to predict the annual output of each farm and sell personalized insurance to farmers.
The application of big data is also reflected in our lives. Wu Shuo and Beijing bus cards generate 40 million credit card records every year. Analyzing these data can optimize the design of urban bus lines. This is the change of big data to transportation services.
The rapid development of the Internet has produced big data, which in turn has promoted the accelerated evolution of various Internet applications. In the foreseeable future, through the full excavation of big data, more new applications will be generated, thus generating more new formats. Will bring us more convenience and surprises. He Hezhen said.
