Knowledge management (KM), which pursues dynamic knowledge creation and sharing within and among organizations, had been boomed since the end of the last century. However, because of some technical limitations as well as cultural barriers, the concept of KM has been getting buried alive, nowadays, in spite of its tremendous potentials to organizations.

... [Show full abstract] conventional KM has has been pointed out tardy and ineffective acquisition of knowledge, which initiates the tragedy in knowledge revolution. Without knowledge to be managed, naturally the usability of knowledge management must be doubted. Therefore, this paper suggests an amended KM framework, especially focused on the autonomous knowledge acquisition process. The suggested methodology for knowledge acquisition is basically processed in an automated manner, but follows the same pattern of human experts' activities for acquiring knowledge by deploying the capabilities of ubiquitous computing technologies. Based on the proposed methodology, this paper also clarifies the relationship between context and knowledge, and hence defines the concept of contextual knowledge. To validate the feasibility of the proposed concepts, CKAS (Context-based Knowledge Acquisition System), a prototype system, is implemented.
