It has long been recognized in academia that associations between knowledge units are often more important than the knowledge unit itself.In a specific knowledge domain,its internal knowledge units will not always be in a completely isolated or free,but have a certain interdependence and mutual promotion relationship.The evolution of the domain knowledge makes the domain knowledge network in time series belong to a dynamic network over time.And the evolution and change of the relationship is relatively small,but it is enough to constitute the micro-rules of structured reorganization of knowledge networks.The structural reorganization of the knowledge network can produce an overall greater than partial sum of knowledge,so that the core knowledge will emerge.Based on the idea of the network science,this study builds a time series knowledge network.This study analyzes the evolution of domain knowledge based on the network Hub structure,clustering coefficient and other indicators,and combines the community discovery algorithm to identify the knowledge community in the domain knowledge network,along the time series.Dynamically track and analyze the core knowledge in the domain knowledge network and the evolution patterns of knowledge communities and knowledge inheritance characteristics.The results show that the evolution of domain knowledge evolves between random and non-random interactions,while in time series,the domain knowledge network evolves from a random-dominated model to a non-random-oriented model.At the same time,in the process of development and evolution of the domain knowledge network,the knowledge units are not always fully connected,but more in a non-connected state.The more mature the domain knowledge develops,the more frequent the knowledge cross-fusion between communities,and the cross-integration The knowledge inheritance mostly occurs between the knowledge communities within the giant branches.In order to reveal the internal mechanism of knowledge development,this study is of great significance for mastering the development of domain knowledge and development model.
