Research On Institutional Repository Resource Service Model Based On Linked Data

Under the background of open access movement,institutional repository construction has become a hot topic in academic research field.Institutional repository is to the development of digital library,its main purpose is to become a colleges,universities and research institutions to collect,store,share,and important channel for the dissemination of academic knowledge assets and the origin of academic innovation.Information resources construction is the core of domestic institutional repository construction,resource content is monotonous,institutional repository storage too little situation has become the obstacles of sustainable development of institutional repository.At present,the main focus and difficulty of institutional repository is:how to speed up the ability of information resource discovery,how to enrich the content of information resources of institutional repository.In this way,the recognition of the institutional knowledge base can be improved,and the publicity and promotion ability of the institutional knowledge base can be further strengthened.In recent years,with the development and dissemination of semantic web technology,the research process of digital resource integration has been accelerated.Especially,since Tim Berners-Lee first proposed" linked data" in 2006,the vision of the semantic web has taken a step closer.Linked data technology has changed the way digital resources are organized and linked,creating a more open network environment for Internet users.Although relational data technology has been used in many areas of research(such as social networks,governments,enterprises,and digital libraries,etc.).However,the correlation data technology lacks deep research and exploration in the integration of digital resources of institutional repository.Moreover,the institutional repository is the redevelopment of the digital library,so we can use the research of related data in the integration of digital library resources to integrate the digital resources of institutional repositories.This article,first discusses the correlation data and the research background and research significance of institutional repository,analyzed the linked data and the research status of institutional repository,and combed the institutional repository,and related basic concepts and theory of correlation data technology.Then,based on the analysis of the correlation data in institutional repository of digital resources integration,the importance of constructing the institutional repository based on linked data resource integration framework,and put forward the institutional repository resources integration method based on linked data,mainly from the institutional repository resource semantic description and semantic association.Then,in institutional repository based on linked data fusion method based on linked data is constructed on the basis of institutional repository resource service model:it mainly including data layer,link layer and application layer,and elaborates on its structure and function.Finally,based on the method of case analysis of institutional repository based on linked data resource service model feasibility verification,the results show that the linked data will be used to build institutional repository is a kind of institutional repository implementation resource sharing and the effective approach of knowledge service,is also a very feasible and valuable.
