In this article, we present the results of a research project aiming to produce annotated resources for three regional languages of France: Alsatian, Occitan, and Picard. These languages cover three different language families (Germanic and two subfamilies of Romance, Oïl and Oc languages) and different sociolinguistic situations. Yet, they all face issues common to many under-resourced languages: lack of human and financial resources and presence of geolinguistic variation. The originality of this project is that it brought together researchers from different fields (sociolinguistics, descriptive linguistics, dialectology, natural language processing, digital humanities) to work together towards the common goal of developing annotated corpora for Alsatian, Occitan, and Picard. This created a favorable and stimulating working environment which could not have been achieved had different research groups worked independently, each on a single language. This article details the annotation process, with a special focus on the delimitation of the tokens and the definition of the part-of-speech tags.42 pagesen-USCreative Commons Attribution-NonCommercial 4.0 InternationalAttribution-NonCommercial 3.0 United Statescorpusannotationstokenizationpart-of-speechAlsatianOccitanPicardArticle
