BabelNet 1.1: an encyclopedic dictionary and a multilingual ontology

BabelNet was created by mapping Wikipedia to the most popular computational lexicon of English (WordNet), producing an "encyclopedic dictionary" that provides babel synsets - concepts and named entities in many languages, connected with semantic relations.

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 1.1.

BabelNet is an "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.

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 1.1 comes with the following features:

  • a fully renovated, appealing Web interface at
  • 5.5 million Babel synsets!
  • increased coverage of nominal and named entities
  • improved Wikipedia-WordNet mapping and sense translations
  • coverage of 6 European languages (coming soon: 40+ languages!)
  • millions of pictures and Wikipedia categories associated with babel synsets
  • linked to DBpedia


  • BabelNet as Linked Open Data
  • coverage of 40+ languages (expected this spring)


The Linguistic Computing Laboratory at Universita di Roma is hiring! A Ph.D. position is open in the field of multilingual lexical semantics for highly qualified candidates with an excellent Master's degree in computer science, computational linguistics or related areas. The successful candidate will join a young, dynamic research team (made up of 2 faculty members, 2 post-docs and 6 Ph.D. students) with solid experience and proven excellence in NLP research. If interested, please send inquiries to Prof. Roberto Navigli,

Note that the Sapienza deadline for submitting applications is July 20 (, but candidates who apply earlier, and are successful, could start a research fellowship (about 1500 euros net per month) immediately and then apply for Ph.D.
