An international expo(博览会) on big data(数据) opened on Wednesday in southwest China’s Guizhou Province, showing the newest scientific and technological creations and achievements in the relevant area, May 26, 2021.
Big data is a lot of sets of information that are put together so they can be used by a computer program. The computer program looks for different kinds of answers or patterns in the data. Big data can have different kinds of information that comes from schools, social media sites, companies, and governments. One set of data can have people’s names and addresses. Another set can have what they like, where they go to school, and how much time they spend on the computer.
President Xi Jinping called for China to speed up its big data strategy(战略) in order to better serve social and economic(经济) development and improve people’s lives. In the past few years big data has been used more often in China. The government uses it to understand how many people travel on buses or trains. The information is then used to make bus or train systems better. Some schools use big data to understand which children may need extra(额外的) help in class. The teacher can give certain students more help or support so those students can succeed in school. The role it plays in tourism is another example. The data travelers share online is offering the tourism industry a lot of information about the country’s scenic areas(景区). 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.
