Russian data from the SynTagRus corpus.

The SynTagRus dependency treebank is being developed by the Computational Linguistics Laboratory, A.A.Kharkevich Institute of Information Transmission Problems, Russian Academy of Sciences, located in Moscow.

Currently the treebank contains over 1,000,000 tokens (over 66,000 sentences) belonging to texts from a variety of genres (contemporary fiction, popular science, newspaper and journal articles dated between 1960 and 2016, texts of online news etc.)

SynTagRus is a human-corrected corpus of Russian supplied with comprehensive morphological annotation and syntactic annotation in the form of a complete dependency tree provided for every sentence. Additionally, the original version of SynTagRus contains other types of annotation, first of all lexical functional annotation in terms of lexical functions as defined in the Meaning-Text model.

It is an integral but fully autonomous part of the Russian National Corpus developed in a nationwide research project and can be freely consulted on the Web: http://www.ruscorpora.ru/instruction-syntax.html
