Roberto Navigli. Roberto Navigli (born 1978) is an Italian computer scientist and professor in the Department of Computer, Control and Management Engineering "Antonio Ruberti" at the Sapienza University of Rome, where he is also the director of the Sapienza NLP Group. His research focuses on Artificial Intelligence, specifically on enabling computers to understand and represent meaning across hundreds of languages, making significant contributions to various fields within Natural Language Processing, including Word Sense Disambiguation, Entity Linking, Semantic Role Labeling and semantic parsing. He created BabelNet, a multilingual knowledge graph that brings together knowledge from resources including WordNet, Wikipedia, Wiktionary and Wikidata. At the core of his research lies the goal of making semantic representations of words and sentences independent of the language in which they are written. More recently, he has focused on Large Language Models (LLMs), leading the Minerva project, the first Italian effort for pretraining a LLM from scratch.

Education 

Navigli obtained his Master of Science degree in Computer Science in 2001 at Sapienza University of Rome, followed, in 2007, by a PhD from the same institution, under the supervision of Paola Velardi. Navigli's doctoral thesis focused on devising and evaluating an innovative knowledge-based algorithm for Word Sense Disambiguation, named Structural Semantic Interconnections.

Career and research 

Navigli was a visiting research fellow and visiting professor of the School of Informatics, University of Edinburgh, the University of Sussex, the University of Wolverhampton and the Center for Advanced Studies of Ludwig Maximilian University of Munich
He then obtained academic positions as researcher, and later associate and full professor, at the Sapienza University of Rome, where he established the Sapienza NLP group. Between 2017 and 2023, Navigli served as a member of the ERC Starting Grant panel for Computer Science and Informatics (PE6).

Navigli was granted a European Research Council (ERC) Starting Grant to fund his work on the creation of BabelNet and multilingual Word Sense Disambiguation, most notably Babelfy, and a subsequent ERC Consolidator Grant to work on sentence-level, language-independent semantic representations, leading to the BabelNet Meaning Representation and its semantic parser, with the goal of creating 'the DNA of language'. These two grants have been highlighted among the 15 projects through which the ERC transformed science.

In 2016, Navigli founded Babelscape, a successful university spinoff company, focused on multilingual neuro-symbolic Natural Language Understanding.
