Abstract

I present a novel (pilot) approach to mapping regional dialects in American English using data collected by the Yale Grammatical Diversity Project. The dataset analyzed consists of acceptability judgment surveys administered online. I use interpolation and tessellation in ArcGIS to project a uniform geographic set of data points, and then the Gabmap clustering tool to identify broader dialect regions. The results correspond closely to traditional dialect boundaries, which is striking, given that (a) the way data was collected, (b) the kind of data collected, (c) the way it was analyzed, and (d) the time period it came from are all very different from the projects that led to previous regions. I then show how Gabmap can be used to explore how regions exhibit varying degrees of distinctiveness, and I emphasize that regions can be characterized not only by the syntactic features they possess, but also by those that they lack.
