We developed a lightweight crowdsourcing platform, Bisame, that aims at collecting part-of-speech (POS) annotations for less-resourced languages, testing it on a regional language from France: Alsatian (about 550,000 speakers). We hypothesized that the speakers of a less-resourced language like Alsatian would be motivated to help developing linguistic resources for their own language, without the need to develop a full-fledged game.
