The era of big data: analyzing the real value of big data

Big data is now familiar to people, and now it can also be useful in the field of public ****decision-making and public ****service, which has a diversified pattern of interests and diversified needs of the society. As China enters the era of big data, and its related topics are endless: the movie "Small Times" said it would be based on big data casting and deletion of scenes; Baidu said that data mining bet on this year's college entrance examination essay questions; is currently in full swing in the World Cup in the big data has not been absent - Deutsche Bank and even with the help of big data to calculate a table of the probability of winning the championship. A table of probability of winning the championship. According to foreign news reports, Deutsche Bank according to each team's FIFA ranking, historical record, player composition and gambling odds and other factors, the establishment of a quantitative analysis model, and according to complex calculations to get a probability of winning the table. Among them, Brazil ranked first, followed by Germany, Spain and France. The final winner is then derived based on certain assumptions.? For the seemingly omnipotent big data, nowadays, in the field of public **** decision-making and public **** service, which has diversified interest patterns and social needs, can it also show its strength? Big data for policymaking navigation? Earlier this year, the much-anticipated "two children alone" policy in various parts of the landing, the National Health and Family Planning Commission Publicity Department Director, spokesman Mao Qun'an has revealed that for the introduction of this policy, the relevant agencies and departments have done nearly 10 years of research on what kind of adjustments to the population policy have been data simulation. Big data can also be used for urban transportation planning, and PADIS has conducted predictive analyses of traffic congestion in certain cities. With the view that we should limit the population and the number of motor vehicles, accelerate the development of public **** transportation of the traditional point of view is different, PADIS predictions show that the population concentration of residential areas and the economic center of the serious deviation is the result of the public demand for commuting to work, traffic deterioration of the root cause, purely to increase the public **** transportation facilities, control people and vehicles can only be raised to stop the boiling water. To this end, the PADIS prescription is to improve urban planning and management, so that the city to the direction of multi-center development. In addition to help the government adjust birth control policy, planning transportation, this system can also rely on its massive data and powerful simulation and prediction capabilities, delayed retirement, pension shortfalls, environmental governance, housing prices and other hot issues to put forward their own "insights", the scope is enough to cover all aspects of our lives. Big data can only assist in decision-making? The charm of big data lies in the ability to analyze huge amounts of data in an unprecedented way to obtain products of great value or deep insights. So does that mean that we can trust computers completely and let data and software help us make decisions?? The answer, of course, is no. Shi Wenzhao, technical director of the PADIS system project and a big data expert at Digital China Information Service Co. believes that an automated decision-making system has not been and should not be created. He said that big data can only assist decision-making but not replace it. Summarizing the experience of these years, the best system should be a perfect combination of human and computer. Big data application is very powerful and will be more powerful, it can realize data mining analysis, policy simulation, indicators of early warning and many other functions, but it is still only a decision-making system. Mining the richness of big data? "Internet Queen" Mary Icke in the "2014 Internet Trends Report" specifically mentioned big data, that in 2014 big data will be more practical, closer than ever to the lives of ordinary people. Starting in 2014 some new types of services that rely on interpreting data to provide solutions will begin to appear, and the trend of big data solving big problems will also emerge. At the same time, she also found that 34% of the information in the available general data has research value, but only 7% of it is tagged, and only 1% has been analyzed. Data access is important, but data that lacks analysis is meaningless.? The real value of big data is not a simple collection of massive amounts of data, but finding the connections between these data and discovering the laws behind them to serve the solution of practical problems. Like mineral deposits, there are poor and rich data. In the current situation, especially in the construction of smart cities, we need to focus on how to revitalize the existing data stock, with a good use of big data incremental, to enhance the city's public **** service capacity and management decision-making level.
