Many of us may have experienced the pleasant surprise of seeing recommended(推荐的)songs after you listen to certain songs on a music app. When we open shopping websites, we are more likely to see things on the home page that we might want to buy.
This is based on data(数据). Data is no longer only about numbers, but information from almost every part of our lives: our location, shopping habits and interests. All of this is called "big data". The sources for big data generally fall into one of three categories: Streaming data, Social media data and publicly available sources.
President Xi Jinping called for China to speed up its big data strategy in order to better serve social and economic development and improve people's lives, the Xinhua News Agency reported. He also asked for greater use of big data in areas like education, social safety and transportation.
In the past few years we have seen big data being used more often in China. The role it plays in tourism is just one example. The data travelers share online is offering the tourism industry a lot of information about the country's scenic areas. After the data is analyzed(分析), different scenic areas can create their own online information for other travelers to see. The information not only tells travelers' reviews, but also tells the scenic areas where services need to be improved.
Big data is also an important growth engine(增长引擎)for economic development. With an annual growth rate of 30 percent, sales of big data services and products in China will reach 1 trillion yuan yearly by 2020, China News Service reported.
