Along with the penetration of ICT in society and the advance and spread of sensors, measurement instruments and observation equipment for gathering information in the real world, the amount of data obtained from various fields has grown exponentially and continues to become more diverse and more frequent in occurrence. Advanced integration and use of big data are expected to bring about science and technology innovation and the creation of intellectual value through new scientific discoveries, with development of the resulting knowledge leading to creation of social and economic value as well as improvement and optimization of services.

This research area will aim for the creation, advancement, and systematization of next-generation core technology solving of essential issues common among a number of data domains, and integrated analysis of big data in a variety of fields.

Specific development targets include technology for stable operation of large-scale data management systems that compress, transfer, and store big data, technology for efficiently retrieving truly necessary knowledge by means of search, comparison, and visualization across diverse information, and the mathematical methods and algorithms enabling such services. In pursuing these studies, with a view to overall system design up to the creation of value for society from big data, the creation, advancement, and systematization of next-generation common core technology highly acceptable to the public will be undertaken, through active efforts at fusion with fields outside of information and communication technology.

Moreover, in this research area collaboration will be encouraged with the related area, “Advanced Application Technologies to Boost Big Data Utilization for Multiple-Field Scientific Discovery and Social Problem Solving,” such as by sharing and use of the next-generation core application technology and data obtained in that research.
