We present here the results of an experiment aiming at crowdsourcing part-of-speech annotations for a less-resourced French regional language, Alsatian. We used for this purpose a specifically-developed slightly gamified platform, Bisame. It allowed us to gather annotations on a variety of corpora covering some of the language dialectal variations. The quality of the annotations, which reach an averaged F-measure of 93%, enabled us to train a first tagger for Alsatian that is nearly 84% accurate. The platform as well as the produced annotations and tagger are all freely available. The platform can easily be adapted to other languages, thus providing a solution to (some of) the less-resourced languages issue.
