Visualization of researcher´s knowledge structure based on knowledge network

In order to promote intuition and accuracy of researcher´s knowledge representation, this paper is focused on the visualization of knowledge structure based on knowledge network. According to the system science theory, the composition of researcher´s knowledge structure is analyzed. A model of researcher´s knowledge network which represents researcher´s knowledge structure is proposed. This model includes knowledge points, knowledge stocks and relationship between knowledge points. After modeling process of knowledge network which includes modeling of knowledge points, calculating of knowledge stocks, modeling of relationship and hierarchical processing of knowledge network, researcher´s knowledge fields and knowledge sub fields can be discovered. A researcher´s knowledge management prototype system is developed based on the above method. The method makes researcher´s knowledge structure visualized intuitively, objectively and quantitatively, which is validated by a case in the end.
