Abstract: In view of the interdisciplinary nature of intangible cultural heritage (ICH), this paper discusses the construction scheme of its classification organization. The thesis introduces the theory and methodology of domain analysis and proposes three steps to realize the construction of the classification organization of ICH information resources, based on the exploration of the construction strategies that fit the characteristics of ICH information resources, and then improvement of the construction process. The study concludes that a systematic taxonomy incorporating grouping techniques is suitable for presenting the organizational structure of ICH information resources, and that a combination of bottom-up and top-down logic should be adopted to realize the design of the taxonomic organization by taking information resources as the basic material and reviewing them together with experts in the field, and then repeatedly validating the design of the taxonomic organization. The thesis illustrates the theory and method of constructing a step-by-step classification organization scheme, which provides a scientific basis for the subsequent organization and content revelation of ICH information resources. It will also provide reference for the construction of classification organization in related disciplines within the industry.
