Log analysis of a SPARQL query in Japanese DBpedia

Abstract

Recently, many and various datasets are published as a Linked Open Data (LOD). 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. In this paper, we analyze access logs of a SPARQL endpoint to show a difficulty of utilizing LOD and introduce our prototype system for sharing SPARQL query.
