RDFDigest+: A Summary-driven System for KBs Exploration

In this paper, we present RDFDigest+, a novel tool that enables effective and efficient RDF/S Knowledge Base (KB) exploration using summaries. The tool employs a diverse set of algorithms for identifying the most important nodes, offering a wide range of possibilities to capture importance. The selected nodes can be combined using multiple state of the art algorithms to generate a complete schema summary graph. In addition, we present a new approach enabling the dynamic exploration of summaries through two novel operations zoom and extend. Extend focuses on a specific subgraph of the initial summary, whereas zoom on the whole graph, both providing granular information access to the end-user.
