This is the main page of the website where linguistic corpora of Meadow Mari language are located. Currently, two corpora are available: the corpus of contemporary written literary Meadow Mari (“the Main corpus”) and the corpus of social media in Meadow Mari. They differ in what kind of texts the contain, but have mostly identical annotation and search capabilities. Here is a brief comparison:
|Main corpus||Social media corpus|
|Language||Meadow Mari||Meadow Mari and Russian|
|Size||2.63 million words||3.59 million words (the Mari part)
15.11 million words (the Russian part)
|Texts||contemporary press, Wikipedia (up to May 2019)||open posts and comments by Mari-speaking vkontakte users (up to May 2019)|
|Language variety||in most cases, standard written literary Meadow Mari or close to it||language of digital communication: closer to the spoken variety, influenced by the dialects and Russian language, contains numerous code switching instances|

A language corpus is a collection of texts in that language which has been enriched with additional linguistic information, called annotation, and, preferably, equipped with a search engine. Here you will find a short list of frequently asked questions about the Meadow Mari corpora.
— Who needs corpora?
First of all, corpora are used by linguists. The search engine and annotation of corpora are designed in such a way that you can make linguistic queries such as “find all nouns in the genitive case” or “find all forms of the word пырыс followed by a verb”. Apart from linguists, corpus can be a useful tool for language teachers, language learners, and even the native speakers.
— Can I use the corpus as a library?
No, these corpora are not designed for that. When you work with a corpus, you make a query, i.e. search for a particular word, phrase or construction, and get back all sentences that contain what you searched for. By default, the sentences are showed in random order. You can expand the context of each of the sentences you get, i.e. look at their neighboring sentences. However, you may do so only a limited number of times for each sentence. Therefore, it is impossible to read an entire text in the corpus. This is done for copyright protection.
— Can I use the corpus as a dictionary?
Each Mari word in the corpus has Russian translation (no English translations are available at the moment). However, they are only provided as auxiliary information for users who do not speak Mari. The translations in the corpus are kept short and simple by design, they do not list all senses and do not provide usage examples like real dictionaries. If you want to know how to translate a word, the right way to do so is consulting a dictionary, e.g. here.
— What is morphological annotation and how do you get it?
The corpora located here are lemmatized and morphologically annotated. Lemmatization means that each word in the texts is annotated with its lemma, i.e. dictionary/citation form. Morphological annotation means that each word is annotated for its grammatical features, such as part of speech, number, case, tense, etc. Since the corpora in question are too large for manual annotation to be feasible, they were annotated automatically with a program called morphological analyzer. The analyzer uses a manually compiled grammatical dictionary and a formalized description of Meadow Mari inflection. The analyzer together with the necessary materials is freely available in my bitbucket repository. Automatic annotation unfortunately means that, first, out-of-vocabulary words are not annotated, and, second, that some words have several ambiguous analyses. Russian sentences in the social media corpus were annotated with the mystem analyzer.
Meadow (or Eastern) Mari is one of several Mari languages, which form a group in the Uralic family. The number of Meadow Mari speakers is estimated at 356,000. Mari languages use Cyrillic orthography based on the Russian alphabet, with several additional letters. There is limited vowel harmony in Mari. Almost all morphological markers are suffixes that mostly attach to the stem agglutinatively. Nominal grammatical categories are number, case, and possessiveness. The direct object can be marked either in the nominative or in the accusative (DOM). The default word order in the sentence is SOV (subject – object – verb).
If you have questions, would like to propose collaboration, or noticed an error in the corpusexcept typos in blogs and social media: these text are left "as is", please contact Timofey Arkhangelskiy. You can also use the Meadow Mari morphological analyzer and the tsakorpus corpus platform, which are open source and freely available.
