Abstract
Just like most XML documents do not contain schema definitions, we can expect the same to be true for some RDF documents - they may come without RDFS or ontology. When presenting such data, we can interpret it only as a directed labeled graph.
It is natural to present the data by visualizing the graph. Since the RDF data can be extremely large, displaying the whole graph is impossible.
The graph is visualized starting by a single suitable node. Then the user is given possibility to further explore the data with the help of our 'node merging' technique, which also saves space.
By combining suitable visualization and navigation techniques we get a tool that can give the user a good idea about the structure of the data.
