The article discusses issues regarding the role of corpus linguistics and interdisciplinary research in contemporary linguistics. The possibilities of using multilingual digital resources in linguistic research have been discussed and the examples of the use of parallel corpora in research on modern vocabulary and phraseology of Slavic languages have been presented. The considerations lead to the conclusion that nowadays, in times when the need to apply natural language mechanisms in information and computer systems and human-computer interaction is growing, it is necessary to develop resources and language processing tools to effectively overcome language barriers. This will allow for closer cooperation between researchers representing different sciences.
