Visual Exploration , Query , and Debugging of RDF Graphs

Semantic Web engineers create and explore the content and structure of RDF graphs in order to build Semantic Web applications. Currently, some Semantic Web development and visualisation tools for Semantic Web engineers are available. However, the tasks of exploring, debugging, and querying RDF graphs have been neglected in the past. This paper evaluates a hybrid visualisation technique of RDF graphs for Semantic Web engineers. A prototype has been implemented representing RDF graphs in different textual views and in a graph visualisation. To examine the usefulness of our approach, a usability test, based on typical use cases of Semantic Web engineers, has been done. Author
