Anatomy: What is "big data" and its application case

Big data can change the way we look at the world, and in Washington this week many experts have gathered to discuss some big data. Below are some examples of references they have mentioned.

The United Nations has established a global pulse, with the primary aim of making better use of large data to enable industries to respond faster and better to the most comprehensive and broadest possible humanitarian crisis. Figure is provided by the United Nations

As a term and a concept, if you don't deal with big data every day, then big data is relatively unfamiliar to you. Even in industry experts, the definition of big data is a hotly debated topic. For some people, the key feature is the capacity of the database, for others, the key feature is the complexity of the data, and some people say that the data concentration and analysis speed. For you and me, perhaps the best way to understand the big data is the amount of data that is infinitely large, which can be influenced by a number of businesses, governments or large groups of organizations whose activities affect tens of thousands of people. In Facebook, the largest social networking site in the United States, similar to China's Sina Weibo, is used to deal with your friends ' referrals, Amazon is used to recommend shopping, and the mobile phone network can provide you with a free location.

These databases, such as each retailer's sales detail, are stored in a loosely formatted format that needs to be in a uniform format in the future. However, for some business companies that are not related to big data, they may not care much about the existence of large data. Now that the significance of big data has grown very clearly, it will have a very deliberate impact on the world.

Below are some examples of references.

Fraud identification

Tax fraud is becoming a growing concern for the Government's desire to cut deficits, when big data can be used to increase the government's process of identifying fraud. Where privacy allows, government departments can synthesize various aspects of data such as vehicle registration, overseas travel data to discover the cost of personal models, so that tax contributions are not superimposed. At the same time a questionable problem arises, and there is no direct evidence of fraud, and these conclusions cannot be used to prosecute individuals. But he can help government departments to identify their audits and other audits as well as some processes.

Medical care and medicine

In the history of medicine, the serialization of human genes has undoubtedly become the greatest and most significant progress of mankind. Now people have the ability to serialize human genetic files, which allows doctors and scientists to predict patients ' susceptibility to certain diseases and other adverse conditions. The main is to reduce the time and cost of the treatment process, and if there is no large data, it seems impossible to talk about.

Increasing the performance and speed of large data collection, storage and analysis tools has reduced the cost from 2 billion dollars to 2000 dollars, shortening the time from 10 years to a week. In any case, these benefits are growing at any time, and these big-span gains have been fully implemented by some cloud computing service providers. Cloud computing services providers are Microsoft, Amazon and the United States Shangtianrui

Humanitarian steering force

In the 2011, the United Nations established the global pulse of the United Nations, with the basic aim of using it in the best way in the age of large data, so that the organization can make faster and better ways to respond to humanitarian crises. In Indonesia and the United States, the project uses social media to track public concerns, which has shown great value, the most holistic of which is reflected in coping with crisis responses and social Science.

Other groups are also working in this direction, including Dataking, an early company founder Jack, who led a data drive in London, where data scientists worked with charities to provide analysis-driven solutions. An organization in the United States, Awhere, is carrying out similar work, using data from satellite imagery in a state-of-the-art project to find and match pools of water in developing countries that may be hotbeds of malaria-bearing mosquitoes.

Privacy

This data often contains a number of detailed potential to display information about us, and gradually aroused our concern about privacy, some deal with large data companies need to take this issue seriously. For example, the United States day Rui information left more impressive is that one of his scientists suggested that we should not simply comply with the legal aspects of privacy protection, these are not enough, companies should comply with Google's principle of not doing evil, and even more should make more positive efforts. The idea coincides with the thrust of the promise of "doing good and Analysis", launched by British data scientist Duncan yesterday, and Duncan now leads the UK in large data analysis. Signatories are committed to taking into account the impact of their analysis and use of data, and they are willing to help more beneficiaries. Full disclosure: At the expense of the days of information Europe, the Middle East and Asia meetings, I spent four days in Washington to attend the day of the core information cooperation Conference.
