the unified information :
A large‐scale electronic data is generated constantly by the progress of ICT utilization and
application in various sectors such as environment, medical care, administration, and education.

It reduces environmental impact, and promotes the sustainable development of the city to utilizing
these heterogeneous and multi‐domain data effectively in an integrated manner.

Therefore, it is proposed to include a specific type of technology to create, integrate, and search the
heterogeneous and multi‐domain data, and deliver the unified information as a fundamental
technology for ICT infrastructure of smart sustainable cities.

Role of the technology
In smart sustainable cities, the environmental monitoring with a huge number of sensing devices
generates a large‐scale electronic data. A large scale electronic data is also generated constantly by
the progress of ICT utilization and application in various sectors such as medical care, administration
and education sector.
Large amounts of generated data is integrated in various forms in each domain, and utilized in cloud
environment with huge data centers and high‐speed networks. It can realize sustainable
improvement of environment, energy, economy, and society to utilize these heterogeneous and
multi‐domain data efficiently.
Thus, the technology is required to create, integrate, and search efficiently and transversely the
heterogeneous and multi‐domain data, and deliver the unified information. The technology can
realize not only the environment impact reduction but also the community revitalization, the
reinforcement of disaster prevention, and the improvement of citizens' life.

This technology enables to provide the highly correlated data set group from enormous data, and is
applicable to the environment impact reduction, the energy management, the remote medical care,
the disaster monitoring, e‐Government, and so on.

There are applications of this technology that can support disaster prevention and monitoring; ICT
utilization in Smart Sustainable city is one of the solutions for this key role in future cities.
During disasters it is very difficult to recognize the extent of overall damage. Dealing with disaster
many troubles occur without information sharing among various organizations and individuals.
The technology can solve these issues by providing the appropriate information from various
information accumulated including science, administrative, and SNS information.
Requirements of the technology

To be able to recognize the damage situation, and make a decision appropriately with the
technology to create, integrate, and search the heterogeneous and multi‐domain data and deliver
the unified information.

Highly correlated data set group can be discovered by searching and integrating transversely the
huge heterogeneous and multi‐domain data with the combination of spatio‐temporal correlation,
ontological correlation, and citational correlation analysis. These huge data include real sensing data,
social sensing data from SNS, Web archive, and scientific database, which are collected and
accumulated via the Internet from various individuals and organizations such as victims, rescuers,
and media.
