Semantic Interconnection Model Of Library Digital Resources Based On Linked Data

With the growing wealth of library digital resources,the type of resource,the carrier of resource and the storage way of resource are not identical,this to some extent hindered the sharing and reusing of resources.In order to optimize the organization of library digital resources,experts have proposed some information integration methods.The emergence and development of semantic web technology has changed all kinds of application of the network,and it also make a huge impact in the library.As one of the key technologies to realize the semantic interconnection,Linked Data showed prominent advantage in resources integration and sharing.It give a simple and effective way to solve the unstructured and semi-structured semantic interconnection of digital resources,not only the interconnection in the same field can be achieved,it can also solve the interconnection in interdisciplinary,so as to realize the transformation of data island to interconnected space.Linked Data has been used in the library currently,but the breadth and depth of library digital resources interconnection has a certain distance for ideal target.To highlight the core value of Linked Data and narrow the gap,it is necessary for Linked Data to play its role in the digital resources interconnection.This paper researches the semantic interconnection model and method of library digital resource based on Linked Data technology.First of all,this paper discusses the current status of library digital resource semantic interconnection base on the related theory of the semantic web,Linked Data and semantic interconnection of digital resources.Secondly,after comparing the four semantic interconnection methods,this paper build the model of library digital resource semantic interconnection based on Linked data,the model mainly includes the six hierarchy,respectively are data layer,the logo layer,description layer,ontology layer,logic layer and application layer.Then,this paper puts forward the concrete implementation method of this interconnection model to realizes the semantic interconnection of library digital resources,it based on the collection and identification of library digital resources,the construction of RDF metadata,the design and construction of the semantic reasoning and semantic mapping based on Linked Data to achieve semantic interconnection of library digital resources.Finally,using the library metadata ontology as the experimental data,and using FaCT++ reasoning machine to complete the reasoning of entity concept semantic,and digging the implied relationship of library metadata ontology,to strengthen the internal correlation of ontology.In the process of semantic mapping based on Linked Data,use the Falcon-AO mapping system to match the similarity of concept,and obtain the correlation of data sets.The results of the experiment show that the model optimized the organization of digital resources to a certain extent,and provide an effective method to solve the problem of heterogeneity of digital resources.
