Russian Learner Translator CorpusСвободное произведение культуры

Russian Learner Translator Corpus (RusLTC) is a bi-directional multiple corpus, which stores English-Russian translations done by university translation students.

The project was initiated in 2011 by enthusiasts from the Translation Studies Department, University of Tyumen (Russia) and enjoyed support from computational linguists with the National Research University Higher School of Economics (Moscow, Russia). It has been unveiled as a fully functional online resource in 2014 at Text. Speech. Dialogue conference in Brno. In 2017 a research proposal partially based on this corpus data received support from the Russian Foundation for Basic Research (RFBR), which gave the project a boost and helped to continue making it publicly available.

Russian

RusLTC includes translations collected from 14 Russian universities, which offer specialist, BA and MA translation programmes. Most translations are produced as part of their routine and exam assignments by (often senior) students in these programmes. There are, however, translations that were submitted to translation contests held by the partner universities, translations from trainees who stu dy translation as a supplementary professional course or have chosen translation as their second higher education (part-time and continuous learning programmes). These student populations and levels of study are reflected in the searchable corpus metadata. Translations and metadata are anonymised.

As of October 16, 2018 RusLTC counts more than 2.3 mln word tokens in total. The English-Russian subcorpus has multiple translations to 402 sources, while Russian-English part includes 125 source-targets sets. The number of translations to a single source averages at 8 (min=1, max=67). Many texts are translations of excerpts from larger sources; the median lengths of translations in the English-to-Russian subcorpus is 380 words. Detailed and automatically updated statistics.


Genres in the corpus

RusLTC is aligned at sentence-level with LF Aligner; the errors in its output are corrected manually. Since September 2018 the query interface is based on a customized version of Arkhangelskiy's Tsakorpus. It supports lexical and PoS search for both sources and targets and returns sentences with the query item along with their targets/sources. The query results can be filtered by 10 metadata fields, including the translator’s gender and affiliation, education type and level, grade for the translation, year and conditions of translation (routine/exam; home/classroom) and source text genre. RusLTC includes texts in 10 genres: academic, informational, educational, essay, technical, fiction, educational, speech, letters, advertisement – see the figure on the right for their distribution). Give it a try! Explore renditions of the challenging lemmas lacking immediate counterparts such as overqualified or lock-in. See how weird analytical passives can get in translated Russian.

RusLTC has an associated translation error annotation project, which uses brat text annotation framework (Stenetorp et al 2012). The annotator follows a pre-defined error typology of 30 hierarchical tags, including good_solution and note (see the typology description and annotation guidelines (in Russian)). As of October 2018 we have annotated 765 translations, including 599 translations (230 K tokens) to 72 sources in English-to-Russian direction. The annotation environment is in everyday classroom use, and this data is growing each year.

RusLTC is downloadable as a customized TMX-file and a plaintext archive.

The corpus structure is based on the following filename conventions. Each text in the corpus receives a unique name starting with the source language code (EN or RU), the number indicating the contributor, the unique number of the source and (in case of translations) the number of an individual translation for the same source. For example, RU_1_35.txt and EN_1_35_3.txt are a Russian source and its third English translation respectively. If a source has only one translation, it still receives number 1 after the third underscore in the filename to identify that it is a translation.

We use separate header and annotation files to store metadata and error annotations. For example, RU_1_35.head.txt is a file containing metadata for the respective text; EN_1_35_3.ann is a file containing the error annotation. The current error statistics is shown in the figure to the left.

We stick to open knowledge philosophy in choosing corpus-building technology, and are happy to make the Corpus available online. To the best of our knowledge RusLTC is the third multiple learner translator corpus available online after MeLLANGE LTC (see Table 1 which outlines LTC-related research as of March 2014).

Error types

Except for its direct classroom applications, RusLTC is used as a source of data for research in Translation Studies, primarily dealing with linguistic properties of translations, translation quality assessment, variation in translation and translational competence.
