Research On The Construction Of Intangible Cultural Heritage Knowledge Graph And The Discovery Of Semantic Relations Based On Graph Database

Intangible cultural heritage is a testimony to the historical development of a nation and contains extremely rich cultural resources.In the current background of big data,in order to realize the effective association and integration of intangible cultural heritage knowledge,dig in-depth intangible cultural heritage knowledge,and provide intangible cultural heritage knowledge discovery and services,digital technology provides new technical means and ways for it.This article mainly builds intangible cultural heritage knowledge graph based on graph database,uses Cypher query language to realize the visual presentation of intangible cultural heritage knowledge,visualizes the intangible cultural heritage knowledge discovery from many aspects,and combs and evolves the relationship between intangible cultural heritage knowledge.Mining,and then realize the intangible cultural heritage digital knowledge service,and at the same time enable people to find out the explicit and implicit correlations from the massive data,and provide the basis for the development of humanities and social culture.Based on this,this article sorts out the domestic and foreign research status of intangible cultural heritage and knowledge graph through literature research,and proposes the research content of this article: Research on the construction of intangible cultural heritage knowledge graph and the discovery of semantic relations based on graph database.Firstly,through the explanation of intangible heritage concepts,classification methods and Grand Canal intangible heritage,the relevant reference sources of intangible heritage knowledge in this article are clarified.Secondly,through the explanation of knowledge map concepts,architecture,Neo4 j graph database,Cypher query language and other related knowledge,Propose a method of constructing an intangible cultural heritage knowledge map based on a graph database.Then,taking the national intangible cultural heritage along the Beijing-Hangzhou Grand Canal as an example,organize related entities and relationships into structured data and store them in the Neo4 j graph database to realize the visualization of intangible cultural heritage.Finally,the Cypher query language is used to discover the semantic relationship of intangible cultural heritage knowledge from many aspects.At the same time,the experimental discoveries are sorted out in-depth relationships and the evolutionary rules are explored.The experiment found that the categories of national intangible cultural heritage projects along the Beijing-Hangzhou Grand Canal are involved in nine categories except traditional medicine.Among them,the intangible cultural heritage projects of traditional skills are the most.From the distribution of the number of intangible cultural heritage along the canal,Jiangsu Province Suzhou City in Zhejiang Province,Hangzhou City in Zhejiang Province,Liaocheng City in Shandong Province,and Cangzhou City in Hebei Province.These four prefecture-level cities have more projects.In addition,Beijing and Tianjin also have more projects in the two municipalities directly under the Central Government.Regarding the canal section,the number of intangible cultural heritages distributed in the Jiangnan Canal is significantly greater than that of other canal sections;from the perspective of the evolution of intangible cultural heritage projects,among the intangible cultural heritage that originated from the Beijing-Hangzhou Canal,Peking Opera and Kunqu opera are in the evolution of other intangible cultural heritage projects.The two projects that have appeared the most.Not only do the intangible heritage of the same category use Peking Opera or Kunqu Opera as one of the evolutionary foundations,but also the intangible heritage of different project categories.This phenomenon also exists;from the perspective of the teacher-inherit relationship between non-genetic inheritors and representative figures,they are not only the same There is a teacher-inheritance relationship between inheritors and representatives of intangible cultural heritage projects,and there may also be a teacher-inheritance relationship between inheritors and representatives of different intangible heritage projects.
