  1. RDF Gravity al113301m@student.etf.rs

  2. al113301m@student.etf.rs Content • 1. Introduction • Problem statement and Existing Solutions • 3. RDF Gravity • 4. Conclusion • 5. References

  3. al113301m@student.etf.rs Problem statmentandexistingsoulitions • A tool for visualizing directed graphs built in RDF and OWL. • Allows users to interact with this kind of data in an intuitive way. • Overview graphs, and • edit them. • Tools avaible as a standalone tool or as a part of a bigger tool. (SemanticStudio, Graphl, Cypher…).

  4. al113301m@student.etf.rs al113301m@student.etf.rs RDF Gravity(RDFGRAphVIsualizationTool ) • Its main features are: • Graph Visualization (Renderers/ Zoom/ Selection) • Filters - enabling specific views on a graph. (Global, Local, Namespace, Instance level) • Full text Search/ RDQL queries • Visualizing multiple RDF files

  5. al113301m@student.etf.rs al113301m@student.etf.rs  Graph Visualization • Select and manipulate • Zoom • Automatic Graph Layout

  6. al113301m@student.etf.rs al113301m@student.etf.rs Graph Navigation • Outgoing and incaming nodes. • Literals • Instances

  7. al113301m@student.etf.rs al113301m@student.etf.rs GraphFiltering • The tool allows a user to apply filters to have specific views on the graph. • Filters enable hiding of particular nodes or edges from the graph. • There are two types of filter : • Global Filters • Local Filters

  8. al113301m@student.etf.rs al113301m@student.etf.rs Global Filters • Global Filters allow a user to hide specific edges and concepts based on type. • They are global.

  9. al113301m@student.etf.rs al113301m@student.etf.rs LocalFilters • Local Filters allow a user to hide or view (include) edges of a particular type from the RDF Graph. •  Local Filters are "one-time filters" and unlike Global Filters, they are not persistent. • Local Filter Panel provides three options on its user interface: • Apply Filter • Include Visible Type • Include Type

  10. al113301m@student.etf.rs al113301m@student.etf.rs Local Filters(2) • Apply Filter: This option is used for applying Local Filter on selected edges from the Local Filter Panel.

  11. al113301m@student.etf.rs al113301m@student.etf.rs Local Filters(3) • Include Visible Type: This option is used for including selected edges from the Local Filter Panel.

  12. al113301m@student.etf.rs al113301m@student.etf.rs Local Filters(4) • Include Type: This option is also used for including selected edges from the Local Filter Panel. • Unlike "Include Visible Type" option, this option will include all selected edges.

  13. al113301m@student.etf.rs al113301m@student.etf.rs Search • Full Text Search: the Query Tab allows a user to input any string, choose what he wishes to search (Resources, Properties or both) and then search for the query.

  14. al113301m@student.etf.rs al113301m@student.etf.rs Search(2) • A user can also make RDQL queries and the resulting triples from the query are directly visible on the Graph Panel.

  15. al113301m@student.etf.rs Conclusion • RDF Gravity is a tool for visualising RDF/OWL Graphs/ ontologies.  • Main Features: • Graph Visualisation • Global & Local Filters • Full Text Search • Visualising Multiple RDF Files
