面向科技文献的多维度学科交叉特性研究

Purpose/Significance] This study explores the change process of interdisciplinary integration under different development stages from multiple dimensions, which helps to enrich the research methods of interdisciplinary characteristics, dig out the core technologies and potential methods to promote interdisciplinary integration, and provide references for the formulation of interdisciplinary related policies. [Methodology/Process] A combination of bibliometrics and natural language processing was adopted in this paper. Coarse-grained analysis of interdisciplinary characteristics was conducted by using indicators of diversity, persistence, stability, and affinity. Simultaneously, fine-grained analysis of interdisciplinary characteristics was conducted: based on technology/method trigger verbs, combined with dependency syntax analysis and domain technical reports, technology/method elements are automatically extracted and filtered, then the results are mapped to disciplines to identify research methods and technical elements related to disciplines. [Results/Conclusion] Taking the digital humanities as an example for empirical analysis, the results indicate that the proposed method can effectively reveal the interdisciplinary characteristics within the field.
