The article discusses the stages of formation of the Department of Applied Linguistics and Dialectology. This department was created on the basis of the Laboratory of Linguistics and Information Technologies of the Institute of Nuclear Physics of the Ural Federal Research Center of the Russian Academy of Sciences. Over the years of its existence, the laboratory has made a significant contribution to the support of the Bashkir language in computer technology. Standards for the code table and keyboard layout for the Bashkir language were developed, a number of software products were localized that created an «infrastructure» for the national language in IT technologies. The employees of the division created linguistic information systems: a machine fund of the Bashkir language, corpus projects, a terminological data bank, which operate on the Internet in the public domain. Significant work was done by Bashkir dialectologists in the early and middle of the 20th century: field material was collected on the reference points of dialects, dialectological dictionaries were published, the dialect system was described, and an atlas of dialects of the national language was prepared. But due to the departure of the generation of dialectologists and the mistakes made by the previous leaders of the IIL in the personnel issue, from the 90s to the present, a systematic scientific study of the Bashkir dialects and dialects has not been conducted at the IIL. The number of expeditions with a unified program for collecting the materials themselves has sharply decreased. The materials of previous expeditions were not digitized, most of them were lost. For more than 30 years, there have been shifts and changes in dialects and dialects that have not been recorded or studied. Modern dialectology puts forward new approaches to the study of dialects, a new methodology for processing field materials has appeared. Taking into account the need to restore research on Bashkir dialectology, in particular, the immediate start of collecting field materials, since the process of the disappearance of the speakers themselves is underway, creating information resources on dialects on their basis, the directorate of the institute and the leadership of the UFIC, it was decided to strengthen the staff of the unit with specialists in dialectology and transform the laboratory to the department. The article deals with new scientific tasks facing the department.
