For example, the health code we used during the epidemic is actually based on big data, collecting the action trajectory of each user, and then automatically generating a green code or a red code. For another example, when the epidemic broke out, Zhejiang used traffic flow big data technology to investigate and analyze vehicles entering from areas with serious epidemics to help improve the efficiency of epidemic prevention and control. In addition, big data is also widely used in speech intelligent recognition, smart cities and information security, medical care, transportation and other aspects.
2. Business process optimization
Big data will also help optimize business processes. Using social media data, web search and weather forecast, we can dig out a lot of valuable data, among which the most widely used big data is the optimization of supply chain and distribution route. From these two aspects, geographic positioning and radio frequency identification track goods and delivery vehicles, and use real-time traffic route data to make more optimized routes.
3. Better understand the needs of users.
The application of big data is currently the most widely known in this field. The focus is on how to use big data to better understand customers, their hobbies and behaviors. Enterprises like collecting social data, browser logs, analyzing text and sensor data very much, so as to understand customers more comprehensively. Generally speaking, the data model is established for forecasting. A simple example is that through the application of big data, telecom companies can better predict the lost customers, Wal-Mart can more accurately predict which products will sell well, the auto insurance industry will understand the needs and driving level of customers, and the government can also understand the preferences of voters.
4. Improve medical care and research and development.
The computing power of big data analysis applications allows us to decode the entire DNA in a few minutes. Let's work out the latest treatment plan. At the same time, it can better understand and predict diseases. Just like the data that people can generate by wearing smart watches, big data can also help patients better treat their diseases. Big data technology has been used by hospitals to monitor the situation of premature and sick babies. By recording and analyzing the baby's heartbeat, the doctor can predict the possible discomfort of the baby. This can help doctors help babies better.
5. Financial transactions
Big data is mainly used for financial transactions in the financial industry. High-frequency transaction (HFT) is an area where big data is widely used. Among them, big data algorithms are applied to trading decisions. Nowadays, many equity transactions are conducted by using big data algorithms. These algorithms now increasingly consider social media and website news to decide whether to buy or sell in the next few seconds.
6. Improve security and law enforcement.
Big data has been widely used in security law enforcement. Presumably, everyone knows that the US Security Agency uses big data to fight terrorism and even monitor people's daily lives. Enterprises use big data technology to defend against cyber attacks. Police use big data tools to catch criminals, and credit card companies use big data tools to stop fraudulent transactions.
