“Big data” has increasingly attracted our attention as an IT keyword since the U.S. announcement of 200 million dollar investment in R&D. This article reviews how the concept evolved and what its essence is. In Japan, Information Explosion (Info-plosion) project (2005-2010) by MEXT and Information Grand Voyage project(2007-2009) by METI were conducted, which had been launched based on quite similar motivation. An actual example video on twitter and blog diffusion and its content analytics shows the new value created by big data. Business applications which utilizes probe information generated by car are also introduced. Big data also are giving an impact of style of research in science:fourth paradigm. Finally the importance of data ecosystem is addressed so that various types of data driven innovation be enabled.
A scientific journal named Synthesiology (kouseigaku) which includes original papers based on the type 2 basic research was newly published in 2008. In the research paper to be published in Synthesiology, authors are requested to show the clear objective of the research, the scenario which leads to the realization of the objective, and the selection and integration of the elemental technologies according to the scenario. In this paper, we have introduced the philosophy of the journal, the circumstances and purpose of the publication, and the results of the analysis of synthetic methodology revealed in the 70 papers which were published in the journal. A kind of methodology called “technological synthesis” has been found to be important, and a continuous follow-up process called “synthesis for social introduction” is also found to be necessary to introduce the research results to society. Precise analysis and the development of the synthesis, use and role of the research scenario are recognized to be necessary in the near future.
Cloud Computing is being promoted from 2007 in Shizuoka University in order to solve many problems resulted by operation and management of information infrastructure, such as Business Continuity Plan, cost saving and etc. As a result, we got high evaluations from many organizations in October 2010. But the Great East Japan Earthquake made us understand that only Cloud promotion has no effect to survive from nature power. This paper describes how to continue functions of University at any great disaster, and introduces the new proposal that can correspond to coming Big Data era.
Open data is becoming one of the policy agendas in Japan. Open data enables public data that has been owned by government agencies to be reused by private entities.
