The intersection of technology and tradition offers unprecedented opportunities for spreading folk culture, mainly through innovative knowledge graph technology. This research delves into the transformative potential of knowledge mapping for folk culture dissemination, with the dual goals of boosting dissemination efficiency and safeguarding our rich cultural heritage. We advocate for integrating scientific methods and theoretical insights to enrich cultural communication, exploring the application of knowledge mapping in folk culture through rigorous quantitative analysis and illustrative case studies. The technology’s application has notably increased the reach and engagement of cultural communication, enhancing audience engagement by 20% and interaction rates by 30% over traditional dissemination methods. Our study highlights knowledge mapping technology as a critical driver for innovating folk culture dissemination, providing essential technical support and offering new pathways for the contemporary communication of traditional culture.
