SPARQL Builder: Constructing SPARQL Query by Traversing Class-Class Relationships for Life Science Databases

Abstract

Abstract. Linked Open Data (LOD), a powerful mechanism for linking different datasets published on the World Wide Web, is expected to increase the value of data through mashups of various datasets on the Web. One of the important requirements for LOD is to be able to find a path of resources connecting two given classes. Because each class contains many instances, inspecting all of the paths or combinations of the instances results in an explosive increase of computational complexity. To solve this problem, we have proposed an efficient method that obtains and prioritizes a comprehensive set of connections over resources by traversing class-class relationships of interest. Based on the method, we developed a system for constructing a SPARQL query named SPARQL Builder. We showcase how to generate a SPARQL query according to user's interest by using the SPARQL Builder system
