Stanford University, specifically its Department of Linguistics, started collaborating with Luxembourg University in 2013, during the sabbatical of prof. Leon van der Torre, who mainly worked with prof. Cleo Condoravdi.
After that, Stanford University hosted several PhD students and post-doc of the University of Luxembourg as visiting researchers. Stanford University is a partner of the H2020 project MIREL, coordinated by the University of Luxembourg, bringing its expertise in Natural Language Semantics and Natural Language Processing. Stanford University is internationally recognized as one of the top universities in the world. Its programs in artificial intelligence and computational linguistics rank among the best in the USA.
The sabbatical of prof. van der Torre was intended to integrate his past results in Deontic Logic with the research in Natural Language Semantics done at Stanford, in order to develop machine-readable approaches suitable to represent deontic statements available in natural language, e.g. norms coming from existing legislation.
From October to December 2017, dr Livio Robaldo was an official visiting scholar at Stanford University, advancing his research in the proper representation of deontic statements in natural language in terms of formulae in reified Input/Output logic.
