Research on the Evolution of Discipline Knowledge based on Concept Flows

In order to grasp the law of development and evolution of discipline knowledge from a more detailed level, this paper analyzes the movement form and law of objective knowledge world concept after analyzing the meaning of knowledge and concept. On this basis, a theoretical model of diachronic concept flow is proposed, and its practical significance is briefly described. Finally, taking the interdisciplinary field of "library & computer" as an example, according to the diachronic frequency data of sparse complex network intermediary concept, the diachronic evolution of discipline knowledge is visualized and analyzed, and the existence of sequential concept flow following the logic growth law is confirmed.
