We present WiBi Explorer, a new Web application developed in our laboratory for visualizing and exploring the bitaxonomy of Wikipedia, that is, a taxonomy over Wikipedia articles aligned to a taxonomy over Wikipedia categories. The application also enables users to explore and convert the taxonomic information into RDF format. The system is publicly accessible at wibitaxonomy.org and all the data is freely downloadable and released under a CC BY-NC-SA 3.0 license
