Through knowledge flows, organizations can provide task-relevant knowledge to workers to fulfill their knowledge-needs. Nevertheless, conventional knowledge flow models do not provide different views of knowledge flow according to the different knowledge-needs of individuals or team workers. In this work, we propose a novel concept and a theoretical model of knowledge-flow view. A knowledge-flow view is a virtual knowledge flow derived from a base knowledge flow to provide abstracted knowledge. According to different workers? knowledge-needs, the knowledge-flow view model abstracts some knowledge nodes of a knowledge flow to generate corresponding virtual knowledge nodes by a knowledge concept generalization mechanism. The virtual knowledge flows not only fulfill workers? different knowledge-needs but also provide effective knowledge support in teamwork.
