RelFinder

RelFinder is a tool based on Adobe Flex that automatically reveals relationships within a set of known objects via arbitrary SPARQL endpoints and displays them as graph visualization. The relationships are found by an algorithm that can be applied to large RDF knowledge bases, such as DBpedia or the whole LOD-Cloud. Interactive features and filtering options are available to reduce the displayed nodes of large graphs.

RelFinder - Interactive Relationship Discovery in RDF Datasets provides a demo application and documentation, including notes on Integrating the RelFinder with a project and hosting it on a server.
