Semantic Fusion And Service Of Cultural Relic Digital Resources Based On Linked Data

China is a long history of ancient civilizations.The ancestors legacy of a large number of precious cultural relics,after years of hard work by civil and media workers and historians,they found and unearthed a number of rare sites and precious cultural relics which record the development of Chinese civilization.Many cultural relics'protection institutions have used the modern information technology to preserve the historical relics digitally,the cultural relics digital resources have been greatly enriched and enriched,and through the online platform free open access to the public to achieve resource sharing.However,through the investigation of digital museums which provide cultural resources services and use found that the digital resources of relics have some problems such as heterogeneous distribution,poor correlation and single service.These problems cause the low efficiency of the utilization of digital resources at the present stage.Therefore,how to effectively discover and access these distributed storage and heterogeneous heritage digital resources,and provide retrieval and service from multiple dimensions is an important problem that needs to be solved at present.In recent years,with the development of the Semantic Web,the World Wide Web has evolved from a document network to a data network,and this evolutionary process mainly relies on linked data.The linked data uses the RDF data model,URI and the HTTP protocol to establish the link between different origin data,and finally forms the global data network.At present,the practice and application of linked data has been deepened and developed in various fields.It has made some process in government information fusion,enterprise information fusion and library information fusion.Therefore,it is necessary to introduce correlative data technology to solve the problem of distributed heterogeneity of existing cultural relic digital resources,to strengthen the semantic fusion of digital resources of other relics in the network environment,and to improve user-oriented service capabilities.This paper investigates literature,combs the relevant research status to analysis the deficiencies.And put forward research content:Semantic fusion and service of cultural relics digital resources based on linked data.Firstly,based on defining the connotation and denotation of cultural relic digital resources,this paper analyzes the function of the linked data technology in the semantic fusion process of the cultural relic digital resources,puts forward the cultural digital resources fusion method and Service method based on linked data.The fusion method includes the description method,the publishing method and the fusion method of cultural relic digital resource based on linked data.Secondly,based on literature and case analysis,according to the features of cultural relics digital resources,this paper put forward semantic service based on linked data,which includes concept retrieval service,browse and recommend service,visualization service,personalized services and so on.This paper also construct digital resource service platform of cultural relics,and analysis function module to provide rich semantic service for users.Finally,this paper makes an empirical study on the field of cultural relic painting,collects digital resources related to cultural relic painting from different data sources,records the resources through the core meta-data standard,and constructs the ontology realization resource of cultural relic painting domain.Resource associated data distribution,and then through Falcon-Ao to complete entity recognition based on ontology mapping,to realize the interconnection with external related data,complete retrieval and browse of digital resources of cultural relic painting on cultural relic digital resource service platform.The research of this paper shows that the theory and technology of linked data is an effective way to realize the semantic description,fusion and service of cultural relic digital resources,and it has an important role in improving the utilization rate of cultural relic digital resources.
