corus 0.10.0

Links to publicly available Russian corpora + code for loading and parsing. 20+ datasets, 350Gb+ of text.

Usage

For example lets use dump of lenta.ru by @yutkin. Manually download the archive (link in the Reference section):

wget https://github.com/yutkin/Lenta.Ru-News-Dataset/releases/download/v1.0/lenta-ru-news.csv.gz

Use corus to load the data:

>>> from corus import load_lenta

>>> path = 'lenta-ru-news.csv.gz'
>>> records = load_lenta(path)
>>> next(records)

LentaRecord(
    url='https://lenta.ru/news/2018/12/14/cancer/',
    title='Названы регионы России с\xa0самой высокой смертностью от\xa0рака',
    text='Вице-премьер по социальным вопросам Татьяна Голикова рассказала, в каких регионах России зафиксирована наиболее высокая смертность от рака, сооб...',
    topic='Россия',
    tags='Общество'
)

Iterate over texts:

>>> records = load_lenta(path)
>>> for record in records:
...     text = record.text
...     ...

For links to other datasets and their loaders see the Reference section.
