As an output of the "MultiJEDI" Starting Grant, funded by the European Research Council and headed by Prof. Roberto Navigli, the Linguistic Computing Laboratory of the Sapienza University of Rome is proud to announce the release of BabelNet 2.0.

BabelNet is a multilingual "encyclopedic dictionary" and a multilingual ontology created by mapping the largest multilingual Web encyclopedia - i.e., Wikipedia - to the most popular computational lexicon of English - i.e., WordNet, and by integrating other lexical resources such as OmegaWiki and the Open Multilingual WordNet. The integration is performed via an automatic linking algorithm and by filling in lexical gaps with the aid of Machine Translation. The result is an "encyclopedic dictionary" that provides Babel synsets, i.e., concepts and named entities lexicalized in many languages and connected with large amounts of semantic relations.

Version 2.0 comes with the following features:

  • 50 languages now covered!
  • seamless integration of WordNet, Open Multilingual WordNet, Wikipedia and OmegaWiki
  • 9.3M Babel synsets
  • 50M Babel senses
  • 18M textual definitions
  • 262M semantic relations
  • 17M synset-associated images
  • Available for download together with Java APIs for programmatic access
  • Also available in RDF/Lemon format and via a public SPARQL endpoint
