Abstract： Dynamic network analysis is one of the key research areas of machine learning and artificial intelligence within the context of complex networks. To combine formal concept analysis with dynamic network analysis method，it is of great significance to study the dynamics of concepts and network eigenvalues in dynamic network. Firstly，this paper put forward the dynamic network formal context，and unified the dynamic network data and formal concept analysis into a data framework. Combined with the real dynamic network data types，one kind of dynamic network formal context was classified and structurally analyzed. Secondly，the concept of dynamic network and the definition of network eigenvalue were proposed，which laid a foundation for the later study of the dynamics of network concept. Then，the definition of the change rate of eigenvalues of various network concepts was given，and the dynamic analysis algorithms of network object concept and network attribute concept were proposed. Finally，the two algorithms were tested by using the data extracted from the core journal database of web of science. Experimental results show that the proposed algorithm can effectively analyze the dynamics of network concepts and their eigenvalues.
