On building knowledge cloud

In this paper, we have extended the "data in the cloud" approach to the "knowledge in the cloud" paradigm. The knowledge cloud model represents an ideal solution for on-demand KaaS on the cloud platform. The design framework for public knowledge service platform previously proposed by the authors can be smoothly migrated into the cloud environment as explained in this paper. The knowledge cloud is a high-usability knowledge source for all knowledge workers, moreover, a collaborative base for knowledge co-creation.
