The Linked Open Data (LOD) Cloud is continuously expanding and the number of complex and large sources is raising.Understanding at a glance an unknown source is a critical task for LOD users but it can be facilitated by visualization or exploration tools.H-BOLD (High-level visualization over Big Open Linked Data) is a tool that allows users with no a-priori knowledge on the domain nor SPARQL skills to start navigating and exploring Big Linked Data.Users can start from a high-level visualization and then focus on an element of interest to incrementally explore the source, as well as perform a visual query on certain classes of interest.At the moment, 32 Big Linked Data (with more than 500.000triples) exposing a SPARQL endpoint can be explored by using H-BOLD.
