Dear all,
the Data and Web Science group at University of Mannheim is happy to
announce the first release of the WebIsA database [1] 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 [2] 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 [3] as a Linked Data endpoint, a SPARQL
endpoint, and downloadable dumps.
All the best,
Sven Hertling
