The informational humidity model (IHM) classifies a message into two modes, and describes communication and community in a novel aspect. At first, a flame message, dry information vs. wet information, is introduced. Dry information is the message content itself, whereas wet information is the attributes of the message sender. Second, the characteristics of communities are defined by two factors: the message sender’s personal specifications, and personal identification. These factors affect the humidity of the community, which corresponds to two phases of knowledge creation. In a rather wet community, members easily specify other members. This is effective for managing memberships and changing knowledge from tacit to formal. In a rather dry community, members barely identify with other members at all. This method is suitable for the formal-to-tacit phase of knowledge creation. Finally, it is discussed how social intelligence should be designed and what features are needed to support knowledge-creating communities.
