RelFinder is a Web application that extracts and visualizes relationships between given objects in RDF data and makes these relationships interactively explorable. Highlighting and filtering features support visual analysis both on a global and detailed level. RelFinder is based on the open source framework Adobe Flex and works with any RDF dataset that provides standardized SPARQL access. It makes heavy use of Web 2.0 concepts and programming techniques like AJAX.

Briefly, the key features of RelFinder are the following:

  • it visualizes the relationships between the given objects as a directed graph.
  • it allows the user to choose the SPARQL endpoint of any linked data server as a source of RDF data.
  • it allows the user to filter the relationships discovered.

The original version of RelFinder appears to be incapable of revealing relationships between objects identified by IRIs. Due to some technical issues related to the connection of RelFinder with linked data servers that serve RDF data containing non - latin characters, the operation of the application is interrupted and no relationships are discovered.

With the support of the Web Science Master Program, organized by the Mathematics Department of the Aristotle University of Thessaloniki and within the course "Knowledge Processing in the Web", with instructor Dr. Charalampos Bratsas, RelFinder has become fully compatible with the greek language and is now capable of revealing relationships between given objects in RDF data served by the DBpedia greek. The alterations in the source code and the design and development of the new version of RelFinder were implemented by gradute student Ioannis Avraam.
