Transaction Modes and Rules in the Perspective of Crowd Science

The crowd intelligence network is a fusion system comprised with physical space, information space and conscious space. All interactions among various agents can be viewed as the transaction activity or behavior in the crowd intelligence network. In this study, we analyze the transaction modes and rules from the perspective of crowd science. We review the transaction modes and rules and further develop four modes for the intelligent transactions based on the modularization level of the transaction objects and the quantity of transaction subjects, including the demand side and the supply side. We also show representative examples to further illustrate rules and features of these transaction modes.
