In this paper, we present a conceptual model for knowledge evaluation. After a literature review, over various definitions on knowledge, we first extracted the main plausible features of knowledge both its nature and meaning. The main features are amount of information, verification of information and retrieval ability of information. We then developed a three dimensional model to evaluate knowledge. The surrounded volume amount these components can represent the knowledge value. To see how powerful our model is, we have considered a case study. It has been shown that the model can evaluate customer knowledge. We extracted different aspects of knowledge value from the literature and showed that they can be also acknowledged by the proposed model. The model provides a general framework for knowledge valuation and can be used to evaluate human and artificial knowledge.

Keywords: knowledge management, knowledge value.
