the Data and Web Science group at University of Mannheim is happy to announce the first release of the WebIsA database  as a Linked Open Data endpoint. The dataset contains 11.7 million hypernym or subsumption relations ("is a") collected from the Web (e.g., "iPhone 4 is a smartphone"), using a set of Hearst-like patterns (see the paper  for details). We provide the data together with confidence scores, rich provenance information, as well as interlinks to DBpedia and YAGO. All in all, the dataset contains more than 470M triples.
The dataset is available at  as a Linked Data endpoint, a SPARQL endpoint, and downloadable dumps.
All the best, Sven Hertling Heiko Paulheim
