Research progress of Bohai culture: in-depth insight and trend analysis from the perspective of knowledge graph

As an important political power in northeast China, the culture of Bohai has a unique position in the history of exchange in Northeast Asia. However, the past research is scattered, systematic sorting and integration is insufficient. Therefore, first of all, this paper systematically collects the research literature of Bohai culture, and expounds the basic principle of knowledge graph technology. On this basis, a knowledge map data system for cultural studies of Bohai is constructed, which can integrate and analyze the information of related research literature, and discover the hot spots and trends of research. Then, this paper determines the literature retrieval strategy and selects academic databases such as China National Knowledge Network (CNKI), Web of Science and Wanfang Data for retrieval. Using “Culture of Bohai”, “history of Bohai” and “Archaeology of Bohai” as keywords, the search method is set. In the course of the experiment, the core issues and development of Bohai culture research were systematically revealed, and visualized. The experimental results show that through cluster analysis, five clear research clusters are formed, which show the main direction of the study of Bohai culture, and provide a new perspective and technical support for the in-depth study of Bohai culture. The research method of Bohai culture based on knowledge graph and visual analysis proposed in this paper effectively solves the limitations of traditional research methods and has high academic value and application prospect.
