Mapping, synthesis and visualization of Czech dialects

Abstract

ABSTRACT Dialects became a traditional research subject of linguists who collect and analyse data from a linguistic perspective and a spatial perspective. Detailed research on the distribution of dialects and their specifics is an important part of preserving every nation's cultural heritage. With the gradual disappearance of dialects in society, this topic is very relevant. The presented paper briefly describes the history of dialect research and the most important outcome in recent years, the Czech Linguistic Atlas (CLA). CLA presents the data only in a very simple form from a cartographic point of view, so a new approach has been applied. A new atlas was created from this data, focusing on a specific area of dialectology – vowels shortening. This new atlas’ internal structure corresponds to the cartographic atlas theory as a system and contains both analytical and synthetic maps. Synthetic maps show areas with similar (and unique in the case of regionalisation) combinations of evaluated attributes. The concept of map synthesis is described, and further research questions are designed.
