Knowledge graph construction of Chinese embroidery evolution based on associating cultural space and critical incidents under intangible cultural heritage

Purpose This research aims to provide a methodology for constructing a knowledge graph (KG) to map the evolution of Chinese embroidery by associating cultural space and critical incidents within the context of intangible cultural heritage (ICH). Design/methodology/approach This study deconstructs the cultural space for ICH into physical, spiritual and societal dimensions and scrutinizes the structural components governing the evolution of embroidery projects. Utilizing examples from the four famous embroideries and four ethnic minority embroidery styles of China, we construct a KG connecting cultural space and critical incidents, enabling the storage, retrieval and discovery of knowledge about the evolution of embroideries. Findings The societal dimension of the embroidery cultural space contains more diverse information than its physical and spiritual aspects. Critical events in the evolution of embroidery are categorized into 15 types and further distinguished as internal and external stimuli. Internal stimuli reflect the gradual, positive transformation of ICH embroidery driven by developmental needs. External stimuli often induce changes that are not always beneficial but directly impact the evolution of embroidery. Originality/value This research offers fresh insights into ICH evolution by linking cultural space and critical incidents and enabling the exploration of implicit, potentially valuable and ultimately comprehensible information through knowledge visualization.
