Navigation in RDF Data

There are already several tools available that are capable of visualizing RDF data. The problem with RDF data is that they tend to be very large. To handle the data, the visualizers cannot display the whole data but rather need to use some kind of navigation. We have designed and implemented such visualizer. This paper describes our approach to the navigation, which was designed specifically with the preservation of the user´s mental map in mind. We also compare our approach to the other visualizers.
