Research On Web Service Semantic Association And Publishing Of Digital Library Based On Linked Data

With the rapid development of new technologies and e-commerce on the Internet,people have great demands on the availability of digital resources and the use of various application software on the Internet.As the main application mode of the Internet,Web services has become the technical support for digital library internship data storage,integration,and sharing.Many scholars have been devoted to studying how digital libraries can better meet the needs of users.Web services of various forms and functions have been continuously developed and deployed in digital library systems.For system developers,if these Web services can be efficiently searched and invoked,not only can the development time of the system be saved,a one-stop integration service for digital libraries can be completed,but also the distribution of digital library resources from different systems can be realized by cross-language and platform operations.With the advent of the Semantic Web era,the introduction of linked data has provided possibilities for solving the above problems.This paper takes the digital library Web service as the research object.First of all,the Web service of most digital libraries does not contain semantic information,and there is no relationship between services and services.This paper proposes a semantic relation model of Web services based onlinked data.Then,the semantic description model of Web services is improved and improved by using ontology relationship and metadata technology.Through the research on the relationship between Web service entities and attributes,the functional semantic relationship between four services and their functions are defined,and services are established.The relationship between services,the construction of a Web service semantic association model based on associated data,and the establishment of the basis for the release of associated data for Web service entities.Based on the semantic linked model of Web services,it follows the four principles of linked data to create and publish Web service entities.Explained the process of creation and publication,including entity naming,entity RDF and correlation,database establishment,D2RQ platform deployment,semantic mapping and finally linked data publication.Finally,the digital library Web service test set is selected to conduct empirical research.The results show that the Web service semantic association model constructed in this paper can effectively describe the semantic information of Web services and make the Web services form a certain correlation relationship,which can be achieved for system developers.The integrated services of the digital library provide an effective way to find and invoke related Web services.
