话语权研究可视化分析：溯源、审视与演进

Purpose/Significance] In the current environment of complex international relations, discourse power is regarded as an important symbol of a countrys soft power. Combing the development of discourse power research is helpful to explore the internal logic of evolution, reveal its theme structure, summarize the evolution trajectory and guide positive development. [Method/Process] Aiming at the measurement deviation existing in the process of data mining, this paper designed the comprehensive retrieval strategy of discourse power research, analyzed the origin of the research literatures by using bibliometrics and visual analysis method, and explored the annual change of the research field of discourse power. The annual change of the optimal theme after cross validation was superimposed on the biclustering map. The discipline diffusion context of discourse power research was explored from the citation domain and the cited domain, the evolution context of research topics in different stages was analyzed, and then the evolution trend of discourse power research was revealed. [Result/Conclusion] The research on discourse power can be traced back to the achievements of Foucaults knowledge archaeology. The research can be integrated into five knowledge domains such as linguistics, politics and sociology. The evolution of overall knowledge has changed from the traditional research topics to the refinement, interdisciplinary, and cross-country cooperation of emerging topics. The evolution path is relatively stable and has obvious national leading effect and policy guiding effect.
