Cultural relics are important material "evidences" for studying human civilization.In recent years,with the attention of the state on the protection of cultural relics and diversified forms of publicity for cultural relics,people's attention to cultural relics has increased significantly,and the demand for digital resources of cultural relics has increased.How to efficiently organize and utilize a large number of cultural relics'digital resources has become a research hotspot.In China,most museums will temporarily construct small-scale knowledge graphs to organize cultural relics' data when conducting special exhibitions.These cultural relics knowledge graphs rely entirely on artificial construction and lack of automated methods.Based on the above background and from the perspective of practical application,this paper studies the automatic extraction technology of cultural relics' relationship in the process of constructing cultural relics knowledge graph,and designs and realizes the construction and display scheme of cultural relics knowledge graph.The specific work is as follows:Firstly,this paper proposes a semi-supervised learning-based algorithm for extraction of cultural relics',relations.In this algorithm,we use the improved tri-training model(collaborative training model with three classifiers)to extract cultural relics' relations automatically.We design a new kernel function to measure the similarity between the extracted results and the relational model,and construct an improved Tri-training model using three different classifiers.It is proved by experiments that our improved model is superior to the original Tri-training model in the extraction of cultural relics'relations.Then,by referring to the existing knowledge mapping technology,this paper designs and implements a knowledge mapping scheme for the field of cultural relics.Taking calligraphy and painting,literature,and former residences of celebrities as examples,we constructed a cultural relics knowledge graph centered on Huang Binhong.Through the evaluation by experts and practical application of the cultural relics knowledge graph,we illustrate the feasibility and accuracy of the cultural relics knowledge graph construction scheme designed in this paper.Finally,based on the above research results,we design and implement a cultural relics knowledge graph construction and display system.This system supports the construction of various thematic cultural relics knowledge graphs and the cultural relics knowledge structure adjustment.This system also supports the functions of cultural relics' data entry,cultural relics' text data processing,cultural relics'knowledge retrieval and dynamic knowledge graph display.
