Graph2VR

Graph2VR visualizes Resource Description Framework (RDF) and Web Ontology Language (OWL) knowledge graphs as immersive three-dimensional virtual reality representations to support exploration and analysis using SPARQL queries.

Key Features:

• 3D knowledge graph visualization: Renders RDF- and OWL-encoded graphs as three-dimensional structures within a virtual reality environment.
• SPARQL query integration: Displays and explores results from SPARQL (SPARQL Protocol and RDF Query Language) queries against graph data.
• dotNetRDF connectivity: Integrates with dotNetRDF to connect to SPARQL endpoints and retrieve linked data in real time.
• Unity-based rendering: Implemented on the Unity platform for real-time rendering of graph structures in VR.

Scientific Applications:

• Linked Data visualization: Visual inspection and interpretation of linked data encoded in RDF and OWL.
• Knowledge graph exploration: Analysis of large-scale knowledge graph topology, entities, and relationships in three dimensions.
• SPARQL-driven data discovery: Exploration and discovery of graph data via SPARQL queries executed against SPARQL endpoints.

Methodology:

Implemented in Unity and integrated with dotNetRDF to query SPARQL endpoints and render RDF/OWL graph data as real-time three-dimensional visualizations in a VR environment.
