Social information infrastructure via ICTs
A large volume of data among human-to-human, human-to-machine, and machine-to-machine is delivered,
shared, processed, and consumed through the ICT infrastructure. The concept of social information
infrastructure is shown in Figure 7. To explain the left-hand side of this figure, more than seven billion people
may connect to build up their own human relationships and communities through the ICT infrastructure. The
traditional telecommunication services and the recent social networking services are connecting people. The
right-hand side of the figure illustrates the concept of the cyber physical system consisting of building,
transport, energy, water, manufacture, health, surveillance, and environment through the ICT infrastructure.
All the physical entities are mapped to the corresponding objects in the cyber world through the ICT
infrastructure. The actual behaviours and presence of the physical world are connected to the equivalent
objects in the cyber world. Human intelligences accumulated by social communities are reflected on the
objects in the cyber world. Therefore, the future social information infrastructure can consist of both the
human platform among people and the platform for the cyber-physical system.
