RDF Class Collection from Distributed LOD

For information on the Internet, by using concepts defined in the format that can be processed by machine, various researches have been made so that a computer understands the Web contents. This is called the Semantic Web, and its practical way has been promoted as Linked Open Data (LOD). When creating an application of interest dataset that was created as an LOD at other places, the URL of a concerned LOD is required to use. However, in order to obtain the URL of the LOD, some work like searching or collecting is required to the application author. Thus we propose to create a system to have or collect the relationship between classes, the class itself and its index into the LOD over all created LOD sites as many as possible. In this article, we present an approach of collecting and sharing the class information created in different place, and the information also is stored as another LOD dataset which can be retrieved by SPARQL.
