Abstract
It is important to activate social communications among citizens. The importance of communication tools supporting for society increases. We need to construct the evaluation method which measures the impact on the society. SIQ (Social Intelligence Quantity) was presented as the evaluation method for communication tools supporting for community. SIQ have two components, SIQ-Personal and SIQ-Collective. SIQ-Personal is the scale for the impact on personal in society, and SIQ-Collective is the scale for communities, society, or groups. It is expected that the construct of the evaluation package for communication tools would make clear the impact of communication tools on society.
