Contemporary society relies heavily upon the massive amount of information connected each other by Internet. Social progress will depend upon the establishment and continuous revision of technologies to enable the rapid and accurate transmission of data, and technologies to allow quick search of massive volume of data to retrieve required information in a timely manner. For this reason, we will conduct fundamental research on database, information retrieval, data mining, geographic information systems, social network analysis, and privacy protection. We also conduct application-oriented research such as health/medical big data analysis, scientific data management, integrated utilization of knowledge bases and search engines, utilization of scholarly data, educational information systems, in cooperation with domain experts.
