Диалектометрический подход к диалектной классификации восточнославянских языков на материале сборника «Восточнославянские изоглоссы»
The article proposes a new dialectometric approach to the division of East Slavic languages. Our dialectometry is based on the material from the collection of articles “Vostochnoslavyanskie izoglossy” (“East Slavic isoglosses”, 1995–2006), which is a generalization of data from atlases of East Slavic languages (Dialectological atlas of the Russian language, Dialectological atlas of the Belarusian language, Atlas of the Ukrainian language). We transferred the VSI maps to electronic format, with each feature presented on the original map stored as a separate image. This procedure made it possible to construct a matrix of features contained in East Slavic atlases. The k-means method was used to construct clustering. New variants of dialect divisions of the East Slavic languages have been obtained, and significant dialectal features that are differential have been identified for the areas. This dialect division is compared with existing ones. The materials of “Vostochnoslavyanskie izoglossy” contain homogeneous data for all three languages, which allows to analyze the territory of the atlases as a single linguistic area and to study the East Slavic languages not only discretely, but also continuously. The article offers an analysis of cross-border dialects of the presented dialect division.
