What are the application fields of big data?

1. Understanding and positioning customers

This is the most well-known application field of Dabaobai. Many companies are keen on social media data dao, browser logs, text mining and other data sets, and create prediction models through big data technology, so as to understand customers, their behaviors and preferences more comprehensively.

Using big data, American retailer Target can even guess when customers will have babies; Telecom companies can better predict customer churn; Wal-Mart can predict product sales more accurately; Auto insurance companies can more truly understand the actual driving situation of customers.

Ski resorts use big data to track and lock customers. If you are an avid skier, imagine that you will receive an invitation from your favorite resort; Or receiving SMS reminders of customized services; Or tell you the most suitable taxi route. . . . . . At the same time, it provides an interactive platform (website, mobile APP) to record daily data-how many landslides, how many climbs, etc. Share this information on social media and compare and compete with family and friends.

In addition, the government campaign also introduced big data analysis technology. Some people think that Obama's victory in the 20 12 presidential election is due to his team's excellent big data analysis ability.

2.

Improve health care and public health.

The ability of big data analysis can decode the entire DNA sequence in a few minutes, which helps us find new treatments and better understand and predict disease patterns. Imagine that when the data of all wearable devices such as smart watches can be applied to millions of people and their various diseases, future clinical trials will no longer be limited to small samples, but include everyone!

Research Kit, Apple's health application, has effectively turned mobile phones into medical research devices. By collecting data about users, you can track how many steps you take in a day, or remind you of the feeling after chemotherapy and the progress of Parkinson's disease. Researchers hope that this process will become easier, more automated, attract more participants and improve the accuracy of data.

Big data technology is also used to monitor the physical condition of premature and sick babies. By recording and analyzing each baby's heartbeat and breathing pattern, we can predict the symptoms of body infection 24 hours in advance, so as to intervene early and save those vulnerable babies who may be in danger at any time.

More importantly, big data analysis helps us to monitor and predict the outbreak of epidemic or infectious diseases, and can combine the data of medical records with some social media data for analysis. For example, Google predicts flu outbreaks based on search traffic. Although the prediction model didn't work on 20 14-because your search for "flu symptoms" doesn't mean that you are really sick, the influence of this big data analysis is becoming more and more known.

Provide personalized service

Big data applies not only to companies and governments, but also to each of us, such as benefiting from data collected by wearable devices such as smart watches or smart bracelets. Jawbone's smart bracelet can analyze people's calorie consumption, activity and sleep quality. Jawbone has been able to collect 60 years' sleep data, analyze some unique insights from it and feed them back to every user. Also benefiting from this is the online platform "Finding True Love". Most dating websites use big data analysis tools and algorithms to match the most suitable objects for users.

4.

Understand and optimize business processes

Big data is also increasingly used to optimize business processes, such as supply chain or distribution path optimization. Tracking goods or transport vehicles through the positioning and identification system, and optimizing transport routes according to real-time traffic data.

Human resources business processes are also being optimized with big data. Sociometric Solutions detects employees' workplaces and social activities by implanting sensors on their badges-which workplaces employees walk around, who they talk to, and even the tone of their communication. In use, Bank of America found the best employees in the call center-they established a group rotation rest system, and their average performance improved by 23%.

If you stick the RFID tag on your mobile phone, keys, glasses and other personal belongings, you can quickly locate them if you accidentally lose them. Imagine that in the future, smart tags may be created and attached to anything. They can not only tell you where the object is, but also tell you the temperature, humidity, motion state and so on. This will open a new era of big data. The field of "big data" seeks * * * information and patterns, so the "small data" bred in it focuses on a single product.

5.

Improve urban and national construction

Big data is used to improve all aspects of our city and country. At present, many big cities are committed to building smart transportation. Vehicles, pedestrians, road infrastructure and public service places are all integrated into the intelligent transportation network to improve the efficiency of resource utilization and optimize urban management and services.

Long Beach, California is using smart water meters to detect illegal water use in real time, which has helped some homeowners reduce their water consumption by 80%. Los Angeles uses the data of magnetic road sensors and traffic cameras to control traffic lights, thus optimizing the city's traffic flow. According to statistics, the city has controlled 4500 traffic lights, reducing traffic congestion by about 16%.

6. Strengthen scientific research

The infinite possibilities brought by big data are changing scientific research. CERN has 150 data centers and 65,000 processors in the world, which can analyze 30pb of data at the same time. This computing power has influenced scientific research in many fields. For example, the census data and natural disaster data needed by the government have become easier to obtain and analyze, thus creating more value for our health and social development.

7. Improve the performance of mechanical equipment

Big data makes mechanical equipment more intelligent and automated. For example, the Toyota Prius is equipped with a camera, a global positioning system and powerful computers and sensors, which can realize automatic driving without human intervention. Xcel Energy launched the first test of "smart grid" in Colorado, installing smart meters in users' homes, and then logging in to the website to check the electricity consumption in real time. "Smart Grid" can also predict usage, so that power companies can plan future infrastructure needs and prevent power exhaustion. In Ireland, warehouse employees of grocery chain Tescos wear special armbands to track the distribution of goods on the shelves and even predict the completion time of a task.

8. Strengthening security and law enforcement capacity

Big data has been widely used to improve security and law enforcement. The National Security Agency (NSA) uses big data technology to detect and prevent cyber attacks (thwarting terrorist plots). The police use big data to catch criminals and predict criminal activities. Credit card companies use big data to detect fraudulent transactions and so on.

2065438+February 2004, Chicago Police Department reported and visited the "list" generated by big data-people who may commit crimes, with the aim of preventing crimes in advance.

9.

Improve motor skills

Now most top sports events use big data analysis technology. The IBM SlamTracker tool for tennis matches tracks the position of a football or the performance of each player in a baseball game through video analysis. Many excellent sports teams also track the nutrition and sleep of athletes outside training. The NFL has developed a special application platform to help all teams make the best decisions according to the grass conditions, weather conditions and players' personal performance during their study, so as to reduce unnecessary injuries to players.

Another cool thing is the smart yoga mat: the sensors embedded in the yoga mat can give feedback on your posture, grade your exercises and even instruct you how to practice at home.

10. Financial transactions

Big data is also widely used in the field of financial transactions. Most stock trading decisions are made through a certain algorithm model. Now, the input of these algorithms will consider data from social media and news networks, so as to make more comprehensive trading decisions. At the same time, according to the needs and wishes of customers, these algorithm models will also change with the changes of the market.
