#' Lemmatization Table based on OpenCorpora Morphological Dictionary
#'
#'  A lemmatization table generated from filtered OpenCorpora morphological dictionary. This table can be useful for simple and fast
#'  "word form-to-lemma" replacement, for example using \code{\link[textstem]{lemmatize_strings}} from \pkg{textstem} package.
#'  Table contains \Sexpr{nrow(rulexicon::hash_lemmas_opencorpora)} words forms of
#'  \Sexpr{length(unique(rulexicon::hash_lemmas_opencorpora$lemma))} lemmas.

#' @details The lemmatization table was generated from original OpenCorpora morphological dictionary
#' after filtering unique pairs of token-lemma and unique tokens (first occurrence for both).

#' @format A data table with \Sexpr{nrow(rulexicon::hash_lemmas_opencorpora)} rows
