_RUSSIAN_SPELLCHECK_BENCHMARK_DESCRIPTION = """
                Russian Spellcheck Benchmark is a new benchmark for spelling correction in Russian language.
                It includes four datasets, each of which consists of pairs of sentences in Russian language. 
                Each pair embodies sentence, which may contain spelling errors, and its corresponding correction. 
                Datasets were gathered from various sources and domains including social networks, internet blogs, github commits, 
                medical anamnesis, literature, news, reviews and more.

_MULTIDOMAIN_GOLD_DESCRIPTION = """
                MultidomainGold is a dataset of 3500 sentence pairs 
                dedicated to a problem of automatic spelling correction in Russian language. 
                The dataset is gathered from seven different domains including news, Russian classic literature,
                social media texts, open web, strategic documents, subtitles and reviews.
                It has been passed through two-stage manual labeling process with native speakers as annotators
                to correct spelling violation and preserve original style of text at the same time.

                The sentences with "ru" tag attached to them have been extracted from GitHub Typo Corpus
