The Russian National Corpus is a representative collection of texts in Russian, counting more than 2 bln tokens and completed with linguistic annotation and search tools

We continue to develop the functionality of the corpus for teaching Russian in schools. Five new rules related to vowel alternation in the root have been added to the Practice Example Generator:

• The letters А and О in root -лаг-/ -лож-
• The letters А and О in root -гар-/-гор-
• The letters А and О in root -раст-/-рос-/-ращ-
• The letters А and О in root -клан-/-клон-
• The letters А and О in root -скак-/-скоч-

You can access the generator page from the RNC for school page by clicking on the corresponding banner.

The English-Russian MultiPARC has been expanded to nearly 253,000 tokens. The addition includes two versions of Anton Chekhov’s play The Cherry Orchard.

The Russian version is a 1983 television production by the State Academic Maly Theatre of the USSR, directed by Igor Ilyinsky. The English version is the 1981 BBC television film The Cherry Orchard, directed by Richard Eyre.

The English version was transcribed at Moscow State Linguistic University. We extend our gratitude to Professor Olga Iriskhanova, Vice-Rector for Research at MSLU, and to Andrey Petrov, research fellow at the SKoDis Center, for their valuable contribution.

By tradition, on the last working day of the year the RNC team sums up the results and reflects on what new features have appeared in the Corpus.

In 2025, the Corpus grew by more than 47 million words. The capabilities of a number of subcorpora were expanded - from historical corpora to the Dialect and Syntactic corpora. Neural-network-based annotation of lemmas and morphology was significantly improved in the Main, Media, Educational corpora, the “Russian classics” and the “From 2 to 15” corpora. Researchers, developers, and teachers now have access to a public API that makes it possible to run search queries programmatically.

The Corpus also continued to develop as a tool for a broad audience - a new service, the “Practice Example Generator”, was launched, along with several new widgets in the Word at a Glance.

We have collected in the image the new features and improvements introduced over the past year that will make your work with the Corpus even more productive and enjoyable. May the New Year bring you many interesting finds and discoveries!

With best wishes for the New Year,
The Russian National Corpus Team
