The Russian National Corpus (Russian: Национальный корпус русского языка||National Corpus of the Russian language) is a corpus of the Russian language that has been partially accessible through a query interface online since April 29, 2004. It is being created by the Institute of Russian language, Russian Academy of Sciences.
It currently contains more than 1 billion word forms[1] that are automatically lemmatized and POS-/grammeme-tagged, i.e. all the possible morphological analyses for each orthographic form are ascribed to it. Lemmata, POS, grammatical items, and their combinations are searchable. Additionally, 6 million word forms are in the subcorpus with manually resolved homonymy.
The subcorpus with resolved morphological homonymy is also automatically accentuated. The whole corpus has a searchable tagging concerning lexical semantics (LS),[2] including morphosemantic POS subclasses (proper noun, reflexive pronoun etc.), LS characteristics proper (thematic class, causativity, evaluation), derivation (diminutive, adverb formed from adjective etc.).
The RNC includes also the following subcorpora:
All the texts have tags bearing metatextual information - the author, his/her birth date, creation date, text size, text genres (general fiction, detective story, newspaper article etc.); all these categories are browsable and searchable separately. It is possible to define a user's subcorpus to search lemmata/POS-grammeme/semantic tags combinations only within this subset.
