[Purpose/significance] The purpose of this paper is to reveal the current status of health informatics re⁃search methods in the domestic information resource management perspective, to explore the characteristics of re⁃search methods applied under different research themes, and to provide a reference basis for the selection of research design methods in this field. [Method/process] Firstly, the study obtained 2154 academic paper abstract data from 61 journals in the field of information resource management from CNKI. Secondly, it utilized BERT model with data aug⁃mentation and the ChatGPT large language model for research method entity extraction. On this basis, a method entity co-occurrence network was constructed. The method entity clusters were classified according to the Louvain communi⁃ty detection algorithm. Finally, the BERTopic model was used to mine research themes and reveal the status of applica⁃
tion of method entities under each theme. [Result/conclusion] Health informatics research methodology entities are broadly categorized into empirical research methods, qualitative research methods, data intelligence and simulation methods, data collection methods and tools, modeling research methods, and information systems analysis and design methods, with significant differences in the distribution of research methods under different research themes. The re⁃sults of the study help to adapt research methods for discipline-specific problems and promote the combined applica⁃tion of multifaceted, mixed, and interdisciplinary methods in health informatics.
