This chapter demonstrates the validity of crowdsourced data by comparing the crowdsourced data from the VinKo project with traditionally collected data from the AThEME project. Both datasets target non-standard language varieties of the South Tyrol, Trentino, and Veneto regions in north-eastern Italy. Three different morphosyntactic phenomena are discussed, each relating to a particular language variety, providing evidence that the crowdsourced data is of comparable quality to the traditionally gathered data and has the added advantage of yielding a larger overall dataset covering a denser location network.
