  2. Outline • Introduction • Related Work • The Visualization Interface Design • The Visual Interface Prototype • Conclusions

  3. Semantic Web • Machine-understandable ability • Two standards are under investigations: • RDF (Resource Description Framework) • Topic Maps • Each of them describes the Semantic Web in a different view.

  4. Semantic Web Visualization • How to Present the full view of the Semantic Web becomes an important research issue. • Visualization techniques play an important role to reveal the concepts of data frameworks. • Visualization techniques have been increasingly applied to the Semantic Web. • Past efforts visualize the Semantic Web on diverse frameworks. • The panorama of the Semantic Web cannot be well displayed.

  5. RDFSViz RDFViz RDF Visualizations

  6. Topic Navigator Tree Map Topic Maps Visualizations

  7. Summary • Various map metaphors have been proposed to be available for the Semantic Web. • IsaViz and RDFViz do not consider the presentation of topic information. • The integration of their features can benefit the visualization of the Semantic Web and help users interact with the visual interfaces.

  8. Our Research • ISWIVE (integrated Semantic Web interactive visualization environment) • ISWIVE visualizes the concept of Topic Maps in the RDF framework. • ISWIVE enhances the interface interoperability by providing a local magnifier panel and an interactive semantic query procedure.

  9. The ISWIVE Design • ISWIVE uses a dual mode visualization. • ISWIVE visualizes the content of the Semantic Web in detail and outlines all the topics and the relationships in a high-level view. • The Semantic Web panorama can be visualized in a complemented way.

  10. The Dual Visualization Layout

  11. The RDF Visualization Algorithm • The multi-scale force-directed algorithm:

  12. The Hv-tree-drawing Algorithm • The original hv-tree-drawing algorithm is used to draw a binary tree. • The extended hv-tree-drawing algorithm:

  13. System Architecture

  14. The Prototype Environment • ISWIVE uses the RDQL query tool and parser provided by the Jena Semantic Web Toolkit. • We have applied RDF Topic Maps (RTM) namespaces for mapping the XML Topic Maps (XTM) to the RDF model. • The System is developed with Java JDK 1.4.1.

  15. The ISWIVE Interface

  16. Visualization of the Topic Tree

  17. Visualization of the Query Results

  18. Conclusions • ISWIVE visualizes the concept of Topic Maps in the RDF framework and presents a complete view of the Semantic Web. • ISWIVE enhances the interoperability and query visualization interface. • A simple, clear metaphor and an inferential query visualization still need further studying.
