Multi-dimensional Element Graph Construction and Spatial Representation of Gardens in the Fuhai Area of Yuanmingyuan Based on Literary Cartography
Published 2025-04-01“…ObjectiveThe integrated knowledge system of “environment – architecture – behaviour – perception” embedded in classical Chinese gardens has not been systematically recognized in the contemporary research system dominated by the study of material entities and combined with the contemporary design theory system, resulting in the disconnection between ontology research and design research of classical gardens, and the inefficiency of the transformation and application of research results. Aiming at the problem of excavating and characterizing multi-dimensional elements in classical gardens, this research reviews imperial poems in the Fuhai area of Yuanmingyuan Garden, summarizes the coupling relationship of key elements, and puts forward a suitable method of knowledge characterization, so as to expand the research path of “immaterial” gardens depicted in the poems.MethodsThe utilization of text mining, knowledge graph and associated technologies, in conjunction with the Forty Scenes of Yuanmingyuan and the Yangshi Lei Archives, along with other historical materials, facilitates the characterization of the imperial poetry texts regarding the Fuhai area in Yuanmingyuan during the Qianlong period. …”
