When people describe big data , they usually indicate that it has 4 " V " characteristics , that is, 4 English descriptions with " V " as the initials : Volume is large, Variety has many modes, Velocity is fast, and Value is large. The first three " Vs " essentially serve the fourth " V " . Imagine , if there are no large data we want to get value , we also worked hard so why toss before the three " V "?
Mr. Wu Gansha, Dean of Intel China Research Institute, said , “Given the low information density of big data , big data is a poor mine , and input-output is better than nothing.” The famous technology reporter Steve Lohr of The New York Times reported in his interview that data Times the age of big data "in the show , the risk of large-value data mining lies , there will be a lot of" false positives "found that , statistically Stanford professor Trevor Hastie's words , is" big in the data haystack in , found meaningful "needle" , its difficulty is that "a lot of hay looks like a needle .
For large value data , Li Guojie aid of traditional Chinese fable "garden gold" , explained the value of big data from another point of view , allegorical story is this :
"There are father and son duo , ranking the village , the camp after the parent orchard disease. , Son sedentary farming , garden gradually barren day. , The father was dying , that Confucius said : Park in the gold sub-plowing to find gold. , No income , even Feeling surprised. It is the autumn of the year , and the grapes and apples in the garden have a good harvest. The son has realized the truth of his father's words."
People are expected , from large data mining the unexpected "great value." Li Guojie may think , in fact , the value of big data is mainly reflected in its driving effect , large data contribution to the economy is not fully reflected in the company's direct income big data , consideration should be given to other industries improve the efficiency and quality of contribution.
Big Data is a typical general-purpose technology , understand the value of GM technology , to know how a "bee model" : the maximum benefit of bees , not their own brewed honey bee pollination, but the contribution of agriculture and forestry - you can say the fall of countless The fruit has no credit for the bees .
Back to the story foregoing , the son of plowing value , not only to turn the garden of gold , but also to promote the orchard after harvest autumn plowing.
For large data once the study in terms of data collection, storage, analysis and transmission capacity , improve the new knowledge even if did not find any universal law or it is totally unexpected , but also greatly promoted, such as computer hardware and software, data analysis, etc. With the development of the industry , the value of big data has gradually been reflected.
Academician Li Guojie believes that we don't need to expect miracles every day , and do more "unpretentious" things , and actual progress will be reflected in solid efforts. Some media always like to promote some eye-catching successful cases of big data , but those engaged in the big data industry should keep a clear head . The absence of hua is normal and the qualitative change of blazing is.
If the "big data" compared to the land of the farmer and his son after the hospital , then the more will not be able to dig out the "gold" of the land area of the General Assembly of it , the answer really is not .
