Problem statment and existing
soulitions
• 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…).

RDF Gravity
(RDF GRAph VIsualization Tool )
• 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

Graph Filtering
• 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

Global Filters
• Global Filters allow a user to hide specific edges and concepts based
on type.
• They are global.

Local Filters
• 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

Local Filter on selected edges from the Local
Filter Panel.

including selected edges from the Local Filter
Panel.

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.

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.

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