Research on Linked Open data of Open Access Infrastructure for Research in Europe
This paper analyzes the OpenAIRE's linked open data from data models,the selection and creation of vocabularies,data mapping,LOD batch generation,data linking,and open external querying in detail,providing a new method and idea for the semantic integration,data interoperability and open access of distributed institutional repositories,academic platform,and periodical platform and so on.However,there are still many problems and challenges:URIs are not stable enough;the data generation process of OpenAIRE LOD is implemented manually,it is mainly accessed through URI,and the quality of data linking needs to be improved.It is recommended to fur-ther enhance data stability,implement automatic data conversion methods,develop multi-path query methods,and strengthen data quality control and evaluation during the implementation of OpenAIRE linked open data.
