This article deals with the problem of development of the dialectological base of the Machine fund of the Bashkir language. Along with the written monuments, folklore material, dialect is one of the most important sources for the study of the historical development and formation of the literary language. The main task of dialectologists is not only the collection but also the storage of dialect materials of the Bashkir language. Taking into account the importance of translation of dialect materials in electronic format and opening of free access to a wide audience to the information provided, the staff of the Laboratory of Linguistics and Information Technologies of the Institute of History, Language and Literature of the Ufa Scientific Center established a dialectological base as a part of the Machine fund of the Bashkir language consisting of three separate databases — lexical database, the database of dialectological atlas and textological database. The lexical database includes information about the dialectal lexicon of the Bashkir language. The database was developed on the basis of dialectal dictionaries compiled and published by the staff of the Institute of History, Language and Literature. The volume of the database is more than 52 000 dialectal units. The database of dialectological atlas is developed on the basis of materials of Dialectological atlas of the Bashkir language. The database allows to select the types of linguistic phenomena (phonetic, morphological, syntactic, lexical), for each type specific isoglosses were identified. Isoglosses allocated 250 strong points of the republic and neighboring regions. The textological database represents illustrative materials collected during numerous expeditions by the staff of the Institute of History, Language and Literature. To date, the database contains more than 500 texts in all dialects of the Bashkir language. Introduced in dialectological base material forms the basis of synchronic and diachronic study of the language features of dialects and sub-dialects of the Bashkir language.
