The colloquium will take place in Montpellier. It is co-organised by two research groups - ReSO (Univ. Paul-Valéry Montpellier 3) and CLLE (CNRS & University Toulouse Jean-Jaurès) - and it relates to the following themes:

• “Linguistic and discursive representation and variation” / “Plurilingualism and linguistic transfer” of the research group ReSO (Recherches sur les Suds et les Orients) ;
• “Occitan, Roman Languages, European languages : description, formalisation, tooling and comparison” (OCRE) of the research group CLLE (Cognition, Langues, Langage, Ergonomie).

This colloquium draws on the two previous meetings (Montpellier, 2016 and 2019) that gathered researchers from several universities, and whose main theme was plurilingualism. The 2023 edition aims to draw particular attention to data and representations, and their link to lexicon and grammar in use.
