Abstract
Crowdsourcing in linguistics has the potential of reaching a large number and a large variety of speakers, as well as creating a geographically fine-grained, well-distributed net of data
points. These opportunities, as well as challenges of questionnaire design, data validity and data
processing are discussed here in reference to the project AlpiLinK (Rabanus et al. 2025). The
citizen science project VinKiamo Südtirol connected to AlpiLinK shows how involvement of
schools in the crowdsourcing effort can help improve data quantity and quality and have an
impact on the participants also in terms of the dissemination of scientifically grounded concepts
of linguistic diversity.
