Research And Application On ICH Evolution Data Model

Intangible cultural heritage(ICH)is the crystallization of wisdom condensed from people’s production and life,which is also a special cultural resource,constantly adjusting its features in the evolution and development process.The protection of the “living” characteristic of ICH is a hot topic in the field of ICH digitization.How to reveal the relationship between the ICH projects and the inner knowledge elements,in the temporal and spatial evolution and development process of ICH,is an urgent problem to be solved in the field of ICH knowledge organization.At present,GIS,spatial analysis and visualization,spatiotemporal modeling and other methods have been widely used in the research of Humanities and social sciences.It is conducive to show the “living” characteristic of ICH to the public through the technologies to sort out the trivial spatiotemporal information in the evolution process of ICH,and the design of relevant visualization methods.This theme has also become a research hotspot of digital protection of ICH.However,the relevant research results mainly focus on the application of GIS,such as visualization,in ICH research,and lack of the deep integration in conceptual theory;most researches are oriented to specific projects,organizing the spatiotemporal information from the perspective of technology,which has poor universality;and there is a lack of research on general data model design and related application methods.As a result,the construction of ICH spatiotemporal data model and related application methods not only fills the gap in current researches,but also plays an extremely positive role in benefiting the researches in related fields and inheriting ICH culture,which has great theoretical and practical significance.In this dissertation,theoretical model construction and practical test are combined to explore the design and application of ICH evolution data model for tourism public information services.Through experiments,the practicability and feasibility of the model are verified.The main research contents and contributions of this thesis are as follows:(1)This dissertation explores the application fields and practical needs of ICH evolution data model,analyzes the data characteristics of ICH evolution,classifies and summarizes the types of information in the text content,and combs the expression ways of temporal and spatial information in text data,laying the foundation for subsequent modeling.(2)This dissertation analyzes the temporal and spatial characteristics of various objects in the evolution of ICH and the description methods in the model;on the basis of analyzing the evolution process of ICH,it combs the conceptual level in the evolution,and analyzes the different meanings of ICH in the macro and micro levels;the dissertation also establishes the conceptual model of ICH evolution with events as the core,so as to make the description of ICH evolution,from detail to global.(3)On the basis of the conceptual model,the class in the concept is transformed into the class in the data model,and the class and its internal structure are defined.The correlation method of macro and micro change based on model is explored,and the idea of " base state with amendments " is used to reduce the redundancy of spatial data.Through the semantic division of the attribute and the design of the database table structure with the combination of horizontal and vertical tables,a unified description method of the ICH diversity features at the data model level is proposed.Finally,taking Nanjing City as an example,this dissertation preliminarily demonstrates the practical application effect of the model through software development and GIS technology,and verifies the validity and practicability of the model.The experimental results show that the model can organize and manage the spatiotemporal information from different ICH projects in a unified way,which has good generality and expansibility;based on the model,the evolution process of ICH can be visualized,and help to find the internal relationship of ICH elements in the evolution process;taking tourism public information service as the application scenario of the model,it provides ideas for promoting the integration of culture and tourism at the information service level.
