Exploring the evolution of global trends and knowledge structure in intangible cultural heritage: insights from topic modeling

Intangible cultural heritage (ICH) research is increasingly interdisciplinary, yet its evolving knowledge structure remains insufficiently mapped. This study applies Structural Topic Modeling to ICH-labelled publications indexed in the Web of Science Core Collection. Eight latent topics are identified and synthesized into three thematic domains, revealing shifting scholarly priorities across technology, sustainability, and spatial governance within ICH-labelled research. The findings provide a structured overview of recent developments in this field.
