| Abstract: | Purpose/significance] The dynamic analysis of the centrality in knowledge networks can reveal the laws and models of the domain knowledge development. The detection has important significance for the insight into the derived, cross and fusion phenomena in the process of knowledge development.Method/process] This study used the centrality analysis technology of the complex network analysis as the main research method and structured domain knowledge networks based on co-occurrence relations of domain keywords. The knowledge development process in specific domains was dynamically tracked and analyzed via time series with core-emergence, bridging-control, and relevance-closeness.Result/conclusion] The results show that the growth rate of knowledge relationships is much higher than the literature and keywords growths; the core-emergence degree of domain knowledge shows a fluctuation growth state; the bridging-control degree between domain knowledge has an upward trend over time; the relevance-closeness degree among domain knowledge gradually lowers along the timeline. These rules of the knowledge evolution help to grasp the venation of the domain knowledge evolution, and play a positive role in revealing knowledge development models and rules. |
