Abstract: Tacit knowledge representations directly affect tacit knowledge transfer and sharing. Tacit knowledge is different from explicit knowledge, because it is difficult to be represented by propositional symbol accurately and completely, but we cannot deny its existence in the human brain. From the epistemological perspective and through the individual tacit knowledge representative model, this paper demonstrates that the tacit knowledge is the person's whole mental imagery which is concerned with particular situation and connections between entities. Based on the information theory and the tacit knowledge characterization model, the paper constructs the tacit knowledge transfer model. There are 8 parts in the tacit knowledge transfer model:the source, output mapping, show, mirror, channel, perception, input mapping and destination of the tacit knowledge. The tacit knowledge transfer model completes the whole transfer process through the eight parts from tacit knowledge demonstration to tacit knowledge absorption. The target of the tacit transfer process is to minimize the tacit knowledge conditional entropy and to maximize the mutual tacit knowledge quantity between entities.

Key words: tacit knowledge existence characterization, context-dependent, mutual tacit knowledge, tacit knowledge transfer model
