The project
MultiJEDI is a 5-year ERC Starting Grant (2011-2016) headed by Prof. Roberto Navigli at the Linguistic Computing Laboratory of the Sapienza University of Rome. The project has two main objectives: creating large-scale lexical resources for dozens of languages, and enabling multilingual text understanding.
Research work
The research work follows many directions each addressing one of the project's goals:
  • BabelNet: a wide-coverage multilingual semantic network (currently in 6 languages)
  • Multilingual Word Sense Disambiguation
  • OntoLearn Reloaded: Ontology learning from scratch
  • WiSeNet: Ontologization of semantic relations
  • Unsupervised Domain Word Sense Disambiguation
  • Multilingual Semantic Relatedness
People
The research team currently consists of the following members: We foster international collaborations with other teams whose competences are relevant to the project.

We are hiring post-docs: if you are interested in computational lexical semantics and statistical machine translation and have a proven publication track record, contact us!
