RelFinder logoInteractive Relationship Discovery in RDF Data

Are you interested in how things are related with each other? The RelFinder helps to get an overview: It 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. The RelFinder is based on the open source framework Adobe Flex, easy-to-use and works with any RDF dataset that provides standardized SPARQL access.

Check out the following links for some examples:


The RelFinder can easily be configured to work with different RDF datasets. It can even be called from remote to access a specific dataset and/or certain objects.


The RelFinder can also be more deeply integrated with your project:

See the following examples of how the RelFinder is integrated into other projects:


The RelFinder is readily configured to access RDF data of the DBpedia project and only requires a Flash Player plugin to be executed (which is usually already installed in web browsers).

Since most DBpedia data has been automatically extracted from Wikipedia and other sources, it cannot be expected to be 100% complete or correct. If you want to help improving the data, read about how to contribute to DBpedia.

All tools on this website are research prototypes that might contain errors. We do not guarantee their correct working and cannot offer comprehensive support.
