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

In February, we welcomed a new “Definitions” widget in the Word at a Glance for 5,500 words. Now, automatically generated definitions are available in the Word at a Glance function within the Main corpus for approximately 96,000 words. This makes the RNC a much more powerful reference tool. These definitions are featured for nouns, adjectives, verbs, and adverbs represented in the corpus.

Definitions are provided for both commonly used words and neologisms, for example, the words кидалт 'kidult' and байопик 'biopic' recently borrowed into Russian. In creating the definitions, we followed four key principles: accuracy, accessibility for middle school students, grammaticality, and conciseness.

Experiments in automatic definition generation have been conducted with the support of the Yandex Cloud Center for Social Technologies. Currently, this feature is available in beta for authorized users. We invite you to leave feedback using the “Rate” button. This will help us improve the quality of the definitions.

In the Word at a Glance’s “Word sketch difference” section, you can now add new words directly on the comparison page, without having to return to the Word at a Glance page. The search fields are located at the top of the page, above the comparison tables.

This functionality is fully available only to authorized users. Unregistered users can view existing comparisons, but must log in to perform their own word comparisons.

The Educational corpus has been expanded by nearly one million word usages. The new update adds a collection of popular science and educational texts: three dictionaries from a well-known series of encyclopedic reference works aimed at middle and high school students (the Young Philologist’s Dictionary, the Young Literary Scholar’s Dictionary, and the Young Artist’s Dictionary), along with widely recognized popular science publications on Russian language and literature.

This addition will increase the proportion of academic texts, enrich the vocabulary with terminology from the humanities, broaden coverage of the history of the language, and provide material for developing exercises and creative assignments in Russian language and literature.

The second part of the update consists of texts from children’s literature, including those recommended for extracurricular reading. The collection features stories and novellas for children and adolescents by V. Inber, T. Alexandrova, Yu. Tomin, A. Usachev, as well as contemporary young authors such as S. Vostokov, A. Ignatova, Yu. Kuznetsova, A. Nikolskaya, and D. Sirotin.

A new feature of the Educational corpus is search by morphemic structure (prefixes, roots, suffixes) within words. Morphemic structure is now available by clicking on words in search results and appears within the corresponding pop-up window.
