Widespread deployment of Semantic Web technologies is accompanied with thousands of vocabularies used in practice. The research community has explored various vocabulary-oriented research topics but suffers from the lack of a large freely accessible vocabulary repository for conducting experiments in real-world settings. To meet the challenge, we release the NanJing Vocabulary Repository (NJVR), which has collected 2,996 vocabularies and instantiations thereof distributed in 4.1 billion RDF triples, all crawled from the real Semantic Web. This paper describes its construction and characterization and also, to illustrate its potential applications, presents experimental results obtained on it about the two research topics, namely, vocabulary matching and ranking.
