Linked Open Data (LOD) is a powerful mechanism for linking different datasets published on the Web, which is expected to create new value of data through mash-up over such various datasets. One of the important needs to extract data from LOD is to find a path of resources connecting given two classes, each of which has an end resource of the path. Based on the concept, we have been developing data acquisition system named SPARQL Builder assisting users in semantic queries for LOD. Through the
