On this page you will find interactive dialectometric visualizations for the linguistic domains of Italian (and Rhaeto-Romance), French and British English. The visualizations are based on digital representations and calculations of the Salzburg dialectometry team around Prof. Hans Goebl.
Basics of dialectometry
Dialectometry (DM) is concerned with finding hidden (ie underlying) structures in geolinguistic networks that are as high-ranking as possible. It is assumed that the dialectal interaction in space is carried out in a law-conform and not chaotic way: see the theorem of "basilectal management of space by man", which is a supporting pillar of the Salzburg-DM.
From an empirical point of view, the DM works primarily with data from linguistic atlases, since these have generally been collected according to a uniform measurement scheme and thus contain intercomparable data.
From a methodological point of view, the Salzburg DM has a numerical and a cartographic (visual) pillar. In numerical terms, the methods of Salzburg-DM have been borrowed from those of "Numerical Classification" and "Quantitative Geography"; in cartographic terms, the focus is on the target-oriented use of all methods used in the field of quantitative and computer-aided cartography. In both cases, care was and is always taken to select methods that fit to the needs of geolinguistics (or linguistic geography).
In addition to the spatial distribution of dialectal similarities and distances, the DM is also interested in the quantitative recording (and subsequent visualization) of the small and large scale interaction between greater dialect domains, whereby these are understood as higher ranking typologically relevant constructs.
The Salzburg DM methods can also be applied to diachronically relevant data. It is also possible to process (in numerical and graphical way) successfully extra-linguistic data with VDM, provided that their basic structure corresponds to that of linguistic atlases.
