Outline of Final Research Achievements

In this research, we investigate query sharing among SPARQL users based on query recommendation and query caching. SPARQL is an RDF query language and it provides a powerful way to access LOD. However, it is not easy to utilize them because it requires not only techniques of SPARQL but also knowledge of datasets and vocabularies that they used for users. We developed query recommendation methods for sharing queries among users, and query caching methods to improveme searching with SPARQL queries.
