The Possibilities of Big Data 2

　This is a continuation of big data. ‘Individual’ can be placed along with ‘infrastructure’. Not only limited to the business field, it is also possible for individuals to take advantage of collective wisdom. 
Services that leverage on integrated content by collective knowledge, such as Cookpad, Kakaku.com, Weather News and others are getting more and more prevalent. Big data might expand Web 2.0 into unprecedented levels, into Web 3.0. 

Based on my calculations, within the 10 years from 1995 to 2005 when digitization first started, the amount of information available has grown by 21 times, and while it is still accelerating, part of it can be attributed to big data. Content = a viewpoint which incorporates people-to-people (P2P) and machine-to-machine (M2M).  

  By the way, “Big Data is Changing the Business” advocates the fact that the use of big data in the public sector, such as in education, medical and public administration spheres. Within education for example, big data can allow education to become more sophisticated. Different people can create different teaching materials, integrate them, and provide the most appropriate teaching material to each student. This is an example of collective wisdom. Field trials in the utilization of big data are required. I would like put a new theme for big data with digital textbooks and movement of teaching materials. 
  Big data is also important in the medical and health care business. However, as the data type of medical records between each hospital differs, there is a fundamental problem of not being able to consolidate inspection data. Although millions of medical information has been integrated in Europe and United States, it has been pointed out that the process is still insufficient in the case for Japan. 
  The obstacles present in this field might pose a bigger challenge when compared to the education field. Although national ID is required for the utilization of big data in government, Japan is still the only country that has not introduced this within developed countries. ‘My Number’ is also not implemented yet, right? 

In the book, three shocking data is published. Based on data provided by Professor Fukao from Hitotsubashi University, investment in information and communication per GDP is at 5% and has increased from 2003. Japan, on the other hand, is at 3% level and has been decreasing since 2001. Although usage by the general user is high, usage by companies remain low.  

According to the white paper on telecommunications published in 2009 on deviation values in information and communications utilization among the seven major industrialized countries, Japan is ranked first in the transportation and logistics business. However, it is also the last in the business management area. This is very shocking. It is a serious issue that IT literacy in the management level is low in Japan. 

  There is also a shocking data from McKinsey which reveals the fact that North America has 5000 petabytes, Europe has 2000 petabytes and Japan with only 400 petabytes in the amount of information accumulated in 2010. In terms of accumulated amount, Japan is only 11% of North America. Both the industry and government in Japan has not realized the importance of information.
The biggest problem is within ourselves, which is for us to recognize the importance of information and data. This is indeed a big challenge.
